Coffee Cell Suspensions as a Platform for Transient Gene Expression Analysis.

Coffea arabica L. is a crucial crop globally, but its genetic homogeneity leads to its susceptibility to diseases and pests like the coffee berry borer (CBB). Chemical and cultural control methods are difficult due to the majority of the CBB life cycle taking place inside coffee beans. One potential solution is the use of the gene cyt1Aa from Bacillus thuringiensis as a biological insecticide. To validate candidate genes against CBB, a simple, rapid, and efficient transient expression system is necessary. This study uses cell suspensions as a platform for expressing the cyt1Aa gene in the coffee genome (C. arabica L. var. Catuaí) to control CBB. The Agrobacterium tumefaciens strain GV3101::pMP90 containing the bar and cyt1Aa genes are used to genetically transform embryogenic cell suspensions. PCR amplification of the cyt1Aa gene is observed 2, 5, and 7 weeks after infection. This chapter describes a protocol that can be used for the development of resistant varieties against biotic and abiotic stresses and CRISPR/Cas9-mediated genome editing.

[Tanshinone â ¡_A inhibits ferroptosis via Nrf2 signaling pathway to protect liver in rats of non-alcoholic fatty liver disease].

This study investigated the protective effect of tanshinone Ⅱ_A(TSⅡ_A) on the liver in the rat model of non-alcoholic fatty liver disease(NAFLD) and the mechanism of TSⅡ_A in regulating ferroptosis via the nuclear factor E2-related factor 2(Nrf2) signaling pathway. The rat model of NAFLD was established with a high-fat diet for 12 weeks. The successfully modeled rats were assigned into model group, low-and high-dose TSⅡ_A groups, and inhibitor group, and normal control group was set. Enzyme-linked immunosorbent assay was employed to determine the content of superoxide dismutase(SOD) and malondialdehyde(MDA) in the serum of rats in each group. A biochemical analyzer was used to measure the content of aspartate aminotransferase(AST), alaninl aminotransferase(ALT), total cholesterol(TC), and triglycerides(TG). Hematoxylin-eosin(HE) staining was used to detect pathological damage in liver tissue. Terminal-deoxynucleoitidyl transferase-mediated nick end labeling(TUNEL) was employed to examine the apoptosis of the liver tissue. Oil red O staining, MitoSOX staining, and Prussian blue staining were conducted to reveal lipid deposition, the content of reactive oxygen species(ROS), and iron deposition in liver tissue. Western blot was employed to determine the expression of Nrf2, heme oxygenase-1(HO-1), glutathione peroxidase 4(GPX4), ferroptosis suppressor protein 1(FSP1), B cell lymphoma-2(Bcl-2), and Bcl-2 associated X protein(Bax) in the liver tissue. The result showed that TSⅡ_A significantly reduced the content of MDA, AST, ALT, TC, and TG in the serum, increased the activity of SOD, decreased the apoptosis rate, lipid deposition, ROS, and iron deposition in the liver tissue, up-regulated the expression of Nrf2, HO-1, FSP1, GPX, and Bcl-2, and inhibited the expression of Bax in the liver tissue of NAFLD rats. However, ML385 partially reversed the protective effect of TSⅡ_A on the liver tissue. In conclusion, TSⅡ_A could inhibit ferroptosis in the hepatocytes and decrease the ROS and lipid accumulation in the liver tissue of NAFLD rats by activating the Nrf2 signaling pathway.

Cotton plants overexpressing the Bacillus thuringiensis Cry23Aa and Cry37Aa binary-like toxins exhibit high resistance to the cotton boll weevil (Anthonomus grandis).

The cotton boll weevil (CBW, Anthonomus grandis) stands as one of the most significant threats to cotton crops (Gossypium hirsutum). Despite substantial efforts, the development of a commercially viable transgenic cotton event for effective open-field control of CBW has remained elusive. This study describes a detailed characterization of the insecticidal toxins Cry23Aa and Cry37Aa against CBW. Our findings reveal that CBW larvae fed on artificial diets supplemented exclusively with Cry23Aa decreased larval survival by roughly by 69%, while supplementation with Cry37Aa alone displayed no statistical difference compared to the control. However, the combined provision of both toxins in the artificial diet led to mortality rates approaching 100% among CBW larvae (LC50 equal to 0.26 PPM). Additionally, we engineered transgenic cotton plants by introducing cry23Aa and cry37Aa genes under control of the flower bud-specific pGhFS4 and pGhFS1 promoters, respectively. Seven transgenic cotton events expressing high levels of Cry23Aa and Cry37Aa toxins in flower buds were selected for greenhouse bioassays, and the mortality rate of CBW larvae feeding on their T0 and T1 generations ranged from 75% to 100%. Our in silico analyses unveiled that Cry23Aa displays all the hallmark characteristics of ß-pore-forming toxins (ß-PFTs) that bind to sugar moieties in glycoproteins. Intriguingly, we also discovered a distinctive zinc-binding site within Cry23Aa, which appears to be involved in protein-protein interactions. Finally, we discuss the major structural features of Cry23Aa that likely play a role in the toxin's mechanism of action. In view of the low LC50 for CBW larvae and the significant accumulation of these toxins in the flower buds of both T0 and T1 plants, we anticipate that through successive generations of these transgenic lines, cotton plants engineered to overexpress cry23Aa and cry37Aa hold promise for effectively managing CBW infestations in cotton crops.

Hawthorn leaf flavonoids alleviate the deterioration of atherosclerosis by inhibiting SCAP-SREBP2-LDLR pathway through sPLA2-â ¡A signaling in macrophages in mice.

ETHNOPHARMACOLOGICAL RELEVANCE: Hawthorn leaves are a combination of the dried leaves of the Rosaceae plants, i.e., Crataegus pinnatifida Bge. or Crataegus pinnatifida Bge. var. major N. E. Br., is primarily cultivated in East Asia, North America, and Europe. hawthorn leaf flavonoids (HLF) are the main part of extraction. The HLF have demonstrated potential in preventing hypertension, inflammation, hyperlipidemia, and atherosclerosis. However, the potential pharmacological mechanism behind its anti-atherosclerotic effect has yet to be explored. AIM OF THE STUDY: The in vivo and in vitro effects of HLF on lipid-mediated foam cell formation were investigated, with a specific focus on the levels of secreted phospholipase A2 type IIA (sPLA2-II A) in macrophage cells. MATERIALS AND METHODS: The primary constituents of HLF were analyzed using ultra-high performance liquid chromatography and liquid chromatography-tandem mass spectrometry. In vivo, HLF, at concentrations of 5 mg/kg, 20 mg/kg, and 40 mg/kg, were administered to apolipoprotein E knockout mice (ApoE-/-) fed by high-fat diet (HFD) for 16 weeks. Aorta and serum samples were collected to identify lesion areas and lipids through mass spectrometry analysis to dissect the pathological process. RAW264.7 cells were incubated with oxidized low-density lipoprotein (ox-LDL) alone, or ox-LDL combined with different doses of HLF (100, 50, and 25 µg/ml), or ox-LDL plus 24-h sPLA2-IIA inhibitors, for cell biology analysis. Lipids and inflammatory cytokines were detected using biochemical analyzers and ELISA, while plaque size and collagen content of plaque were assessed by HE and the Masson staining of the aorta. The lipid deposition in macrophages was observed by Oil Red O staining. The expression of sPLA2-IIA and SCAP-SREBP2-LDLR was determined by RT-qPCR and Western blot analysis. RESULTS: The chemical profile of HLF was studied using UPLC-Q-TOF-MS/MS, allowing the tentative identification of 20 compounds, comprising 1 phenolic acid, 9 flavonols and 10 flavones, including isovitexin, vitexin-4″-O-glucoside, quercetin-3-O-robibioside, rutin, vitexin-2″-O-rhamnoside, quercetin, etc. HLF decreased total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and non-high-density lipoprotein cholesterol (non-HDL-C) levels in ApoE-/- mice (P < 0.05), reduced ox-LDL uptake, inhibited level of inflammatory factors, such as IL-6, IL-8, TNF-α, and IL-1ꞵ (P < 0.001), and alleviated aortic plaques with a thicker fibrous cap. HLF effectively attenuated foam cell formation in ox-LDL-treated RAW264.7 macrophages, and reduced levels of intracellular TC, free cholesterol (FC), cholesteryl ester (CE), IL-6, TNF-α, and IL-1ß (P < 0.001). In both in vivo and in vitro experiments, HLF significantly downregulated the expression of sPLA2-IIA, SCAP, SREBP2, LDLR, HMGCR, and LOX-1 (P < 0.05). Furthermore, sPLA2-IIA inhibitor effectively mitigated inflammatory release in RAW264.7 macrophages and regulated SCAP-SREBP2-LDLR signaling pathway by inhibiting sPLA2-IIA secretion (P < 0.05). CONCLUSION: HLF exerted a protective effect against atherosclerosis through inhibiting sPLA2-IIA to diminish SCAP-SREBP2-LDLR signaling pathway, to reduce LDL uptake caused foam cell formation, and to slow down the progression of atherosclerosis in mice.

Characterisation of new in vitro models and identification of potentially active drugs in angiosarcoma.

Angiosarcoma is a rare soft tissue sarcoma originating from endothelial cells. Given that current treatments for advanced disease have shown limited efficacy, alternative therapies need to be identified. In rare diseases, patient-derived cell models are crucial for screening anti-tumour activity. In this study, cell line models were characterised in 2D and 3D cultures. The cell lines' growth, migration and invasion capabilities were explored, confirming them as useful tools for preclinical angiosarcoma studies. By screening a drug library, we identified potentially effective compounds: 8-amino adenosine impacted cell growth and inhibited migration and invasion at considerably low concentrations as a single agent. No synergistic effect was detected when combining with paclitaxel, gemcitabine or doxorubicin. These results suggest that this compound could be a potentially useful drug in the treatment of AGS.

Bioinformatics Analysis of Modified Lugen Formula in the Treatment of Influenza:Perspectives from the Virus-Host Interaction Network / 中药新药与临床药理

Objective To explore the therapeutic mechanism of Modified Lugen Formula(Phragmitis Rhizoma,Cicadae Periostracum,Batryticatus Bombyx,Lonicerae Japonicae Flos,Glycyrrhiza,Menthae Haplocalycis Herba,Notopterygii Rhizoma et Radix,Puerariae Lobatae Radix,Bupleuri Radix)in treating influenza from the virus-host interaction interface.Methods The phytocompounds were first collected from the HERB database,and then potential active compounds were screened out by Lipinski's rules of five.The targets of active compounds were further predicted through the SwissTargetPrediction platform.Differentially expressed genes(DEGs)were determined from the human H1N1 influenza dataset GSE90732 available in the Gene Expression Omnibus database(GEO).H1N1-Homo sapiens-related protein-protein interactions(PPIs)were gathered from the Pathogen-Host Interaction Search Tool(PHISTO).The above mentioned bioinformatic datasets were integrated.Then a PPI network and a Formula-virus-host interaction network were constructed using Cytoscape.Functional enrichment analyses were performed by using R software.Finally,molecular docking was carried out to evaluate the binding activities between the key compounds and targets.Results A total of 1 252 active compounds,1 415 targets,951 influenza-related DEGs,and 10 142 H1N1-Homo sapiens-related PPIs were obtained.There were 72 intersection targets between the Modified Lugen Formula and influenza.Functional enrichment analyses showed that these targets are closely related to host defense and programmed cell death.The network topological analysis showed that active compounds in the Modified Lugen Formula,such as oleanolic acid,γ-undecalactone,and longispinogenin,regulate viral proteins M2,NA,NS1,and HA and/or the host factors HSP90AA1,NRAS,and ITGB1,thus exert therapeutic effect.Molecular docking results confirmed that these compounds had a good binding ability with the targets.Conclusion Multiple active ingredients in Modified Lugen Formula directly target influenza virus proteins and/or host factors,thereby play an anti-influenza role in multiple dimensions,including inhibiting virus replication,regulating host defense and cell death.This study provides a theoretical basis for further experimental analysis of the action mechanism of the Modified Lugen Formula in treating influenza.

Highly oxygenated guaiane-type sesquiterpene lactones from Artemisia sacrorum and their antihepatoma activity.

The ethanol and EtOAc extracts of Artemisia sacrorum exhibited inhibitory effect against HepG2, Huh7, and SK-Hep-1 cell lines with inhibitory ratios of 65.5%, 28.1%, 84.6%, and 93.5%, 82.0%, 89.0% at 200 µg/mL. Twenty-three undescribed guaiane-type sesquiterpene lactones, artemisacrolides A‒W, were isolated from A. sacrorum under the guidance of antihepatoma activity. Their structures were elucidated by spectral data (HRESIMS, IR, UV, 1D and 2D NMR), ECD calculations, and a single-crystal X-ray diffraction. Artemisacrolides A‒U were guaiane-type sesquiterpene lactones possessing α-methylene-γ-lactone and containing acetoxyl groups at C-8, and artemisacrolides V and W represented the first report from the genus Artemisia with a 1,10-rearranged guaiane-type sesquiterpene lactone. Antihepatoma assay suggested that artemisacrolides A‒U demonstrated better inhibitory activity in Huh7 and SK-Hep-1 cells than those of HepG2 cells. Among them, nine compounds exhibited significant inhibitory activity against Huh7 cells with IC50 values of 8.2-14.3 µM, superior or equal to that of sorafenib; seven compounds demonstrated obvious activity against SK-Hep-1 cells with IC50 values of 13.5-19.2 µM, which were equivalent to that of sorafenib. Artemisacrolides B and E were the most active ones in three human hepatoma cell lines with IC50 values of 21.9, 8.2, 16.9 and 22.6, 9.0, 17.3 µM.

[Comparison on blood-prostate barrier permeability of tanshinone extract and corresponding major monomers].

In this study, the transmittance of tanshinone Ⅱ_A(Tan Ⅱ_A) and cryptotanshinone(CTS) through the blood-prostate barrier and their distributions in the prostate tissue were compared between tanshinone extract(Tan E) treatment group and the corresponding monomer composition group under the equivalent dose conversion in vitro and in vivo. First, the human prostate epithelial cell line RWPE-1 was cultured in vitro for 21 days for the establishment of a blood-prostate barrier model, and the transmission of Tan Ⅱ_A and CTS through the barrier model was investigated after administration of Tan E and corresponding single active components. Second, SD rats were administrated with 700 mg·kg~(-1) Tan E, 29 mg·kg~(-1) CTS, and 50 mg·kg~(-1) Tan Ⅱ_A by gavage, and plasma and prostate tissue samples were collected at the time points of 2, 4, 8, 12, and 24 h. The Tan Ⅱ_A and CTS concentrations in the samples were determined. The results showed that in the cell model, the cumulative transmission amounts of CTS and Tan Ⅱ_A in the extract at each time point were higher than those of the corresponding single active components(P<0.01). In rats, after the administration of Tan E, the concentrations of Tan Ⅱ_A and CTS in rat plasma and prostate were higher than those of the corresponding single active components. This study demonstrated that the coexisting components in Tan E promoted the penetration of its main pharmacological components Tan Ⅱ_A and CTS through the blood-prostate barrier. The findings provide a theoretical and experimental basis for the application of Tan E in the clinical treatment of prostate-related diseases.

Complementary and integrative interventions for PTSD.

ABSTRACTTo treat the impact of trauma, most current evidence supports the use of trauma-focused psychotherapy as the first line approach. However, millions of individuals exposed to trauma worldwide seek Complementary and Integrative Health (CIH) therapies in hopes of achieving wellness above and beyond reducing symptoms. But what is the evidence for CIH interventions? What are potential pitfalls? Given the growing popularity of and strong interest in CIH, EJPT is featuring research on these approaches in this special issue. The papers range from common interventions such as mindfulness to the use of service dogs and scuba diving to alleviate trauma related symptoms. A featured editorial highlights the importance of defining when, where, and how placebo responses work. Nonspecific elements of treatment such as positive expectations, therapeutic rituals, healing symbols, and social interactions are identified as factors influencing treatment response and scientists looking to add to the CIH evidence base are encouraged to consider the impact and methodological challenges these elements present. CIH interventions more specifically recognize and harness some of these factors in addition to intervention-specific factors such as attention or emotion regulation along with focus on overall wellbeing. The body of work in this special issue supports the emerging evidence for meditative and relaxation-based interventions and illustrates a creative but nascent state of the field. Cross-intervention mechanisms that may play a role in achieving wellness, such as arousal reduction, emotion regulation, posttraumatic growth, and positive affect are highlighted. The trauma field would benefit from accumulation of evidence for promising CIH interventions, evaluation of potential mechanisms, and examination of health and wellbeing outcomes. With the paucity of high-quality trials, it would be premature to recommend CIH interventions as first-line treatments. However, the emerging literature on CIH continues to advance our understanding of what works and how these interventions exert their effects.

Complementary and Integrative Health (CIH) interventions for trauma that target holistic wellness above and beyond symptom reduction are increasingly used in the real world, though the evidence base lags.Papers in this issue support the emerging evidence for efficacy of mindfulness or other meditative or relaxation-based interventions.This special issue illustrates creative approaches but also the need for continued research establishing efficacy, evaluating more inclusive outcomes (e.g. a sense of wellbeing or ability to pursue valued life goals), and identifying potential mechanisms.

Rod-specific downregulation of omega-3 very-long-chain polyunsaturated fatty acid pathway in age-related macular degeneration.

Docosahexaenoic acid (DHA; 22:6) plays a key role in vision and is the precursor for very-long-chain polyunsaturated fatty acids (VLC-PUFAs). The release of 32- and 34-carbon VLC-PUFAs and DHA from sn-1 and sn-2 of phosphatidylcholine (PC) leads to the synthesis of cell-survival mediators, the elovanoids (ELVs) and neuroprotectin D1 (NPD1), respectively. Macula and periphery from age-related macular degeneration (AMD) donor retinas were assessed for the availability of DHA-related lipids by LC-MS/MS-based lipidomic analysis and MALDI-molecular imaging. We found reduced retina DHA and VLC-PUFA pathways to synthesize omega-3 ELVs from precursors that likely resulted in altered disks and photoreceptor loss. Additionally, we compared omega-3 (n-3) fatty acid with DHA (22:6) and omega-6 (n-6) fatty acid with arachidonic acid (AA; 20:4) pathways. n-3 PC(22:6/22:6, 44:12) and n-6 PC(20:4/20:4, 40:8) showed differences among male/female, macula/periphery, and normal/AMD retinas. Periphery of AMD retina males increased 44:12 abundance, while normal females increased 40:8 (all macula had an upward 40:8 tendency). We also showed that female AMD switched from n-3 to n-6 fatty acids; most changes in AMD occurred in the periphery of female AMD retinas. DHA and VLC-PUFA release from PCs leads to conversion in pro-survival NPD1 and ELVs. The loss of the neuroprotective precursors of ELVs in the retina periphery from AMD facilitates uncompensated stress and cell loss. In AMD, the female retina loses peripheral rods VLC-PUFAs to about 33% less than in males limiting ELV formation and its protective bioactivity.

Neurofeedback for post-traumatic stress disorder: systematic review and meta-analysis of clinical and neurophysiological outcomes.

Background: Posttraumatic stress disorder (PTSD) is a debilitating condition affecting millions of people worldwide. Existing treatments often fail to address the complexity of its symptoms and functional impairments resulting from severe and prolonged trauma. Electroencephalographic Neurofeedback (NFB) has emerged as a promising treatment that aims to reduce the symptoms of PTSD by modulating brain activity.Objective: We conducted a systematic review and meta-analysis of ten clinical trials to answer the question: how effective is NFB in addressing PTSD and other associated symptoms across different trauma populations, and are these improvements related to neurophysiological changes?Method: The review followed the Preferred Reporting Items for Systematic Reviews and Meta analyses guidelines. We considered all published and unpublished randomised controlled trials (RCTs) and non-randomised studies of interventions (NRSIs) involving adults with PTSD as a primary diagnosis without exclusion by type of trauma, co-morbid diagnosis, locality, or sex. Ten controlled studies were included; seven RCTs and three NRSIs with a total number of participants n = 293 (128 male). Only RCTs were included in the meta-analysis (215 participants; 88 male).Results: All included studies showed an advantage of NFB over control conditions in reducing symptoms of PTSD, with indications of improvement in symptoms of anxiety and depression and related neurophysiological changes. Meta-analysis of the pooled data shows a significant reduction in PTSD symptoms post-treatment SMD of -1.76 (95% CI -2.69, -0.83), and the mean remission rate was higher in the NFB group (79.3%) compared to the control group (24.4%). However, the studies reviewed were mostly small, with heterogeneous populations and varied quality.Conclusions: The effect of NFB on the symptoms of PTSD was moderate and mechanistic evidence suggested that NFB leads to therapeutic changes in brain functioning. Future research should focus on more rigorous methodological designs, expanded sample size and longer follow-up.

Neurofeedback (NFB) was found to have moderate beneficial effects on PTSD symptoms, and positive effects on secondary outcomes such as depression and anxiety, according to a meta-analysis of seven randomised controlled trials (RCTs).The beneficial effects of NFB were observed across diverse populations, including those with different types of trauma (military and civilians) and from different ethnic backgrounds.Results suggest that modulation of alpha rhythm might be a viable NFB protocol in patients with PTSD, as changes in neurophysiological functioning, such as connectivity in the Default Mode Network (DMN) and Salience Network (SN), were observed post-NFB and were correlated with a decrease in PTSD severity.

Art at the Start: A controlled trial and close observation of parent-infant art therapy intervention.

This two-part study seeks to evidence art therapy intervention for parent-infant attachment relationships, looking at improvements to wellbeing and relationships. Study one was a controlled trial with 105 participating parent/caregivers and their infants (0-3-years), identified due to concerns about their relationship. They were quasi-randomized to attend a 12-week art therapy group or treatment as usual. Measures focused on parents' wellbeing and their perceptions of their relationship with their infant. In study 2 we analyzed video footage from the first and penultimate sessions of a sample of 37 dyads, looking for observable changes in the different channels of communication upon which attachments are predicated. The controlled trial showed intervention participants had significantly improved parental wellbeing, significant increases in attachment warmth and significant decreases in intrusion. This contrasted with the control sample who showed a significant decrease in wellbeing, stable warmth, and significant increases in intrusion. The observation study showed that there was a significant increase in the communicative behaviors from the parents to the infant which would support attachments between the first and penultimate sessions. We conclude that these results make a robust case for the inclusion of art therapy within the range of interventions available for at risk early relationships.

Este estudio en dos partes busca evidenciar la intervención terapéutica de arte para las relaciones afectivas progenitor-infante, mirando las mejoras al bienestar y las relaciones. El primer estudio se trata de un ensayo controlado con la participación de 105 progenitores/cuidadores y sus infantes (0-3 años), identificados en atención a preocupaciones acerca de su relación. Ellos fueron asignados cuasi al azar para participar en un grupo de terapia de arte o seguir el tratamiento acostumbrado. Las medidas se enfocan en el bienestar de los progenitores y sus percepciones acerca de sus relaciones con sus infantes. En el estudio 2 analizamos grabaciones de video de la primera y penúltima sesiones de un grupo muestra de 37 díadas, buscando cambios observables en los diferentes canales de comunicación sobre los cuales se fundamenta la unión afectiva. El ensayo controlado mostró que los participantes de la intervención habían mejorado significativamente su bienestar como progenitores, mejoras significativas en la calidez de la afectividad y significativas disminuciones en la intrusión. Esto contrastó con el grupo muestra de control que mostró una significativa disminución en el bienestar, una estable calidez y significativos aumentos en la intrusión. El estudio de observación mostró que había un aumento significativo en los comportamientos comunicativos de progenitores a infantes lo cual apoyaría los acoplamientos entre la primera y penúltima sesiones. Concluimos con que estos resultados formulan un caso sólido para la inclusión de la terapia de arte dentro de la gama de intervenciones disponibles para relaciones tempranas bajo riesgo.

Cette étude en deux parties s'est attachée à examinant l'intervention de thérapie artistique pour les relations d'attachement parent-nourrisson, étudiant les améliorations dans le bien-être et les relations. La première étude a consisté en un essai contrôlé avec 105 parents/personnes prenant soin des enfants et leurs bébés (0-3 ans), ayant été identifiés du fait d'inquiétudes à propos de leur relation. Ils ont été quasiment randomisés pour participer à un groupe de thérapie par l'art ou le traitement habituel. Les mesures ont mis l'accent sur le bien-être des parents et leurs perceptions de leur relation avec leur bébé. Dans la deuxième étude nous avons analysé des prises à la vidéo de la première et de la dernière session d'un échantillon de 37 dyades, cherchant des changements observables dans les différentes chaînes de communication sur lesquelles reposent les attachements. L'essai contrôlé a montré que les participants à l'intervention faisaient preuve d'améliorations importantes dans leur bien-être parental, dans la chaleur de l'attachement et de diminutions importantes dans l'intrusion. Cela a contrasté avec le groupe de contrôle qui a fait preuve d'une baisse importante du bien-être, d'une chaleur stable et d'augmentations importantes dans l'intrusion. Cette étude d'observation a montré qu'il y avait une augmentation importante des comportements communicatifs de la part des parents envers les bébés qui soutiendrait les attachements entre la première et la dernière session. Nous concluons que ces résultats présentent des arguments solides en faveur de l'inclusion de la thérapie par l'art au sein d'une éventail d'interventions disponibles pour les relations précoces à risque.

Framing the work: A coparenting model for guiding infant mental health engagement with families.

When working with families of infants and toddlers, intentionally looking beyond dyadic child-parent relationship functioning to conceptualize the child's socioemotional adaptation within their broader family collective can enhance the likelihood that clinical gains will be supported and sustained. However, there has been little expert guidance regarding how best to frame infant-family mental health therapeutic encounters for the adults responsible for the child's care and upbringing in a manner that elevates their mindfulness about and their resolve to strengthen the impact of their coparenting collective. This article describes a new collaborative initiative organized by family-oriented infant mental health professionals across several different countries, all of whom bring expansive expertise assessing and working with coparenting and triangular family dynamics. The Collaborative's aims are to identify a means for framing initial infant mental health encounters and intakes with families with the goal of assessing and raising family consciousness about the relevance of coparenting. Initial points of convergence and growing points identified by the Collaborative for subsequent field study are addressed.

Cuando se trabaja con familias de infantes y niños pequeñitos, el mirar intencionalmente más allá del funcionamiento de la relación diádica niño-progenitor para conceptualizar la adaptación socioemocional del niño dentro de la amplitud del colectivo familiar puede mejorar la posibilidad de que los logros clínicos sean apoyados y mantenidos. Sin embargo, ha habido poca guía de expertos acerca de cómo enmarcar mejor los encuentros terapéuticos infante-familia de salud mental para los adultos que son responsables del cuidado y crianza del niño de una manera que se eleve su estado consciente acerca de y su determinación de reforzar el impacto del colectivo en el proceso de la crianza compartida. Este artículo describe una nueva iniciativa colaborativa organizada por profesionales de la salud mental infantil orientados hacia la familia en varios diferentes países, todos los cuales aportan su conocimiento amplio evaluando y trabajando con las dinámicas familiares de crianza compartida y triangular. Las metas de este esfuerzo Colaborativo son identificar un medio para enmarcar los encuentros y la proporción de salud mental infantil con familias que se proponen evaluar y crear consciencia familiar acerca de la relevancia de la crianza compartida. Se abordan los puntos iniciales de convergencia y puntos de crecimiento identificados por el esfuerzo Colaborativo para subsecuentes estudios en el campo.

En travaillant avec des familles de nourrissons et de petits enfants, le fait de regarder délibérément au- delà du fonctionnement de la relation dyadique enfant-parent afin de conceptualisation l'adaptation socio émotionnelle de l'enfant, au sein de leur collectif familial plus large, peut accroître la probabilité que les gains cliniques seront bien soutenus et prolongés. Cependant il y a eu peu de directive experte concernant la meilleure manière d'encadrer les rencontres thérapeutiques nourrisson-famille de santé mentale pour les adultes responsables du soin de l'enfant et de son éducation d'une manière qui élève la pleine conscience et la détermination qu'il y a à renforcer l'impact de leur coparentage collectif. Cet article décrit une nouvelle initiative collaborative organisée par des professionnels de la santé mentale du nourrisson centrés sur la famille au travers de plus pays différents, tous étant de grands experts évaluant et travaillant avec des dynamiques de coparentage et de famille triangulaire. Les buts de cette collaboration sont d'identifier un moyen d'encadrer des rencontres de santé mentale initiales et les apports des familles avec le but d'évaluer et d'améliorer la conscience de la famille quant à la pertinence du coparentage. Les premiers points de convergence et de développement identifiés par la collaboration pour des études sur le terrain à venir sont discutés.

Placental AA/EPA Ratio Is Associated with Obesity Risk Parameters in the Offspring at 6 Years of Age.

During pregnancy, maternal polyunsaturated fatty acids (PUFA) are transferred to the fetus through the placenta by specific FA transporters (FATP). A higher perinatal exposure to n-6 over n-3 PUFA could be linked to excess fat mass and obesity development later in life. In this context, we aimed to assess the associations between long chain PUFAs (LC-PUFAs) (n-6, n-3, and n-6/n-3 ratios) measured in the placenta at term birth with obesity-related parameters in the offspring at 6 years of age and assess whether these associations are dependent on the placental relative expression of fatty acid transporters. As results, the PUFAn-6/PUFAn-3 ratio was 4/1, which scaled up to 15/1 when considering only the arachidonic acid/eicosapentaenoic acid ratio (AA/EPA ratio). Positive associations between the AA/EPA ratio and offspring's obesity risk parameters were found with weight-SDS, BMI-SDS, percent fat mass-SDS, visceral fat, and HOMA-IR (r from 0.204 to 0.375; all p < 0.05). These associations were more noticeable in those subjects with higher expression of fatty acid transporters. Therefore, in conclusion, a higher placental AA/EPA ratio is positively associated with offspring's visceral adiposity and obesity risk parameters, which become more apparent in subjects with higher expressions of placental FATPs. Our results support the potential role of n-6 and n-3 LC-PUFA in the fetal programming of obesity risk in childhood. For the present study, 113 healthy pregnant women were recruited during the first trimester of pregnancy and their offspring were followed up at 6 years of age. The fatty acid profiles and the expression of fatty acid transporters (FATP1 and FATP4) were analyzed from placental samples at birth. Associations between LC-PUFA (n-6, n-3, and n-6/n-3 ratios) and obesity risk parameters (weight, body mass index (BMI), percent fat mass, visceral fat, and homeostatic model assessment of insulin resistance (HOMA-IR)) in the offspring at 6 years of age were examined.

Implicit States of Connectivity in the Clinical Practice of Jungian Psychoanalysis and Andean Shamanism.

This paper will describe the spiritual states of "oneness" experienced by Andean shamans in relation to oceanic states in early infancy and working with trauma in Jungian analysis. The author's work exploring implicit energetic experience with Andean shamans will be referenced with comparisons made to depth psychology, in both theory and in practice. Definitions of Q'echua terms describing different psychic meditative states that Andean shamans enter into will be provided as Andean medicine people have a much more developed language for conceptualizing these experiences. A clinical vignette will be presented that demonstrates how the spaces of implicit connection that occur between an analyst and analysand in the analytic setting can be a catalyst for healing.

Cet article décrira les états spirituels d'unité dont les chamanes des Andes font l'expérience, en les mettant en lien avec les états océaniques de la petite enfance et le travail avec le traumatisme dans l'analyse Jungienne. Le travail de l'auteur, d'explorer l'expérience énergétique implicite chez les chamanes des Andes, fera référence à des comparaisons avec la psychologie des profondeurs, dans la théorie et dans la pratique. Des définitions de termes Quechua seront fournies pour décrire les différents états psychiques méditatifs dans lesquels entrent les chamanes des Andes, les médecins-chamanes des Andes ayant un langage bien plus développé pour conceptualiser de telles expériences. Une vignette clinique sera donnée pour montrer comment les espaces de connexion implicite qui se produisent entre un analyste et un analysant dans la situation analytique peuvent catalyser les processus de guérison.

Study on the difference and correlation between the contents and toxicity of aristolochic acid analogues in Aristolochia plants.

ETHNOPHARMACOLOGICAL RELEVANCE: The nephrotoxicity and carcinogenicity induced by traditional Chinese medicines (TCMs) containing aristolochic acids (AAs) and related compound preparations have greatly limited their clinical application. While the toxicity of AA-I and AA-II is relatively clear, there are marked differences in the toxic effects of different types of aristolochic acid analogues (AAAs). Thus, the toxicity of TCMs containing AAAs cannot be evaluated based on the toxicity of a single compound. AIM OF THE STUDY: To systematically investigate the toxicity induced by Zhushalian (ZSL), Madouling (MDL) and Tianxianteng (TXT) as representative TCMs derived from Aristolochia. MATERIALS AND METHODS: AAA contents in ZSL, MDL and TXT were determined using HPLC. Subsequently, mice were treated for 2 weeks with high (H) and low (L) dosages of TCMs containing total AAA contents of 3 mg/kg and 1.5 mg/kg, respectively. Toxicity was evaluated using biochemical and pathological examination and was based on organ indices. Correlations between AAA contents and induced toxicity were analysed using multiple methods. RESULTS: Of the total AAA content, ZSL contained mainly AA-I and AA-II (>90%, of which AA-I accounted for 49.55%). AA-I accounted for 35.45% in MDL. TXT mainly contained AA-IVa (76.84%) and other AAAs accounted for <10%. Short-term toxicity tests indicated that ZSL and high-dose MDL induced obvious renal interstitial fibrosis and gastric injury, whereas TXT (high and low dosages) caused only slight toxicity. Correlation analysis suggested that AA-I might be the critical hazard factor for toxicity. CONCLUSIONS: The toxicity of TCMs containing AAAs cannot be generalised. The toxicity of TXT is relatively low compared with those of ZSL and MDL. The toxicity of Aristolochia depends mainly on the AA-I content; therefore, control of AA-I levels in TCMs and related compound preparations is required to reduce the risk of toxicity associated with the use of Aristolochia herbs in clinical settings.

Dual receptor NIR-II organic nanoparticles for multimodal imaging guided tumor photothermal therapy.

The second near-infrared (NIR-II) fluorescence imaging has attracted continuous attention due to its excellent penetration depth and high spatial resolution. Compared with other fluorophores, NIR-II fluorophores, especially NIR-II organic small molecule fluorophores, are favored because of their controllable structure and good biocompatibility. In this study, we designed and synthesized an S-D-A-D-S type small molecule FEA. However, a new molecule was accidentally obtained in the process of synthesis, which was proved to be a double receptor (A-A) type small molecule, namely S-D-A-A-D-S type organic small molecule FEAA. Compared with FEA molecules, FEAA exhibits superior fluorescence performance and can effectively prevent fluorescence quenching. The fluorescence emission of its nanoparticles (NPs) reaches 1109 nm, extends to about 1400 nm, and has a Stokes shift of up to 472 nm. Subsequently, we realized fluorescence/photoacoustic dual-mode imaging (FI/PAI) of nude mouse liver, and finally effectively ablated 4T1 tumor by photothermal therapy (PTT). In general, FEAA NPs exhibit good fluorescence, photoacoustic, and photothermal effects, and are an excellent multifunctional NIR-II organic small molecule fluorophore. As far as we know, there are few reports on A-A type organic small molecules, most of which are cyanines or D-A-D type structures. Therefore, this study has good exploratory significance and reference value for the discovery of NIR-II fluorophores.

Paeoniflorin protects against cisplatin-induced acute kidney injury through targeting Hsp90AA1-Akt protein-protein interaction.

ETHNOPHARMACOLOGICAL RELEVANCE: Paeonia lactiflora Pall has been used in Chinese Medicine for thousands of years, especially having anti-inflammatory, sedative, analgesic and other ethnic pharmacological effects. Moreover, Paeoniflorin is the main active ingredient of the Paeonia lactiflora Pall, and most are used in the treatment of inflammation-related autoimmune diseases. In recent years, studies have found that Paeoniflorin has a therapeutic effect on a variety of kidney diseases. AIM OF THE STUDY: Cisplatin (CIS) is limited in clinical use due to its serious side effects, such as renal toxicity, and there is no effective method for prevention. Paeoniflorin (Pae) is a natural polyphenol which has a protective effect against many kidney diseases. Therefore, our study is to explore the effect of Pae on CIS-induced AKI and the specific mechanism. MATERIALS AND METHODS: Firstly, CIS induced acute renal injury model was constructed in vivo and in vitro, and Pae was continuously injected intraperitoneally three days in advance, and then Cr, BUN and renal tissue PAS staining were detected to comprehensively evaluate the protective effect of Pae on CIS-induced AKI. We then combined Network Pharmacology with RNA-seq to investigate potential targets and signaling pathways. Finally, affinity between Pae and core targets was detected by molecular docking, CESTA and SPR, and related indicators were detected in vitro and in vivo. RESULTS: In this study, we first found that Pae significantly alleviated CIS-AKI in vivo and in vitro. Through network pharmacological analysis, molecular docking, CESTA and SPR experiments, we found that the target of Pae was Heat Shock Protein 90 Alpha Family Class A Member 1 (Hsp90AA1) which performs a crucial function in the stability of many client proteins including Akt. RNA-seq found that the KEGG enriched pathway was PI3K-Akt pathway with the most associated with the protective effect of Pae which is consistent with Network Pharmacology. GO analysis showed that the main biological processes of Pae against CIS-AKI include cellular regulation of inflammation and apoptosis. Immunoprecipitation further showed that pretreatment with Pae promoted the Hsp90AA1-Akt protein-protein Interactions (PPIs). Thereby, Pae accelerates the Hsp90AA1-Akt complex formation and leads to a significant activate in Akt, which in turn reduces apoptosis and inflammation. In addition, when Hsp90AA1 was knocked down, the protective effect of Pae did not continue. CONCLUSION: In summary, our study suggests that Pae attenuates cell apoptosis and inflammation in CIS-AKI by promoting Hsp90AA1-Akt PPIs. These data provide a scientific basis for the clinical search for drugs to prevent CIS-AKI.
