RESUMEN

This work established a quantitative method to access the shear stability of aerobic granular sludge (AGS) and validated its feasibility by using the mature AGS from a pilot-scale (50 tons/day) membrane bioreactor (MBR) for treating real municipal wastewater. The results showed that the changing rate (ΔS) of the peak area (S) of granule size distribution (GSD) exhibited an exponential relationship (R2≥0.76) with the shear time (y=a-b·cx), which was a suitable indicative index to reflect the shear stability of different AGS samples. The limiting granule size (LGS) was defined and proposed to characterize the equilibrium size for AGS after being sheared for a period of time, whose value in terms of Dv50 showed high correlation (R2=0.92) with the parameter a. The free Ca2+ (28.44-34.21 mg/L) in the influent specifically interacted with polysaccharides (PS) in the granule's extracellular polymeric substance (EPS) as a nucleation site, thereby inducing the formation of Ca precipitation to enhance its Young's modulus, while Ca2+ primarily interacted with PS in soluble metabolic product (SMP) during the initial granulation process. Furthermore, the Young's modulus significantly affected the parameter a related to shear stability (R2=0.99). Since the parameter a was more closely related (R2=1.00) to ΔS than that of the parameter b or c, the excellent correlation (R2=0.99) between the parameter a and the wet density further verified the feasibility of this method.

RESUMEN

BACKGROUND: The sexual interest of postmenopausal women is a crucial aspect of their overall well-being. Despite its importance, factors influencing postmenopausal sexual interest, particularly in Asian women, remain understudied and poorly understood. AIMS: To investigate the various factors influencing sexual interest in postmenopausal women in Malaysia. METHODS: A cross-sectional study was conducted of postmenopausal women attending a gynecology or primary care clinic in a teaching hospital in Malaysia. OUTCOMES: We investigated how interpersonal dynamics and cultural norms-including the physical and mental health of women and their partners, as well as their sexual values-affect menopausal sexual interest as measured by the Menopausal Sexual Interest Questionnaire. RESULTS: Women in the study reported an average sexual interest, with a mean score of 32.8 (SD, 9.4) out of 70 on the Menopausal Sexual Interest Questionnaire. Multivariable analysis results showed that higher personal sexual values (odds ratio [OR], 2.65; 95% CI, 1.26-5.61) and spousal sexual values (OR, 2.68; 95% CI, 1.22-5.86) were significantly associated with higher menopausal sexual interest. There was a positive correlation between the physical fitness of spouses and menopausal sexual interest, with women who rated their spouses as very fit or fit (OR, 3.22; 95% CI, 1.15-9.00) or moderately fit (OR, 2.63; 95% CI, 1.05-6.63) showing higher menopausal sexual interest as compared with those whose spouses were very unfit or unfit. Women with normal stress levels (OR, 5.89; 95% CI, 1.03-33.62) and mild to moderate stress levels (OR, 8.13; 95% CI, 1.53-43.22) reported higher menopausal sexual interest. CLINICAL IMPLICATIONS: This study emphasizes a holistic approach to postmenopausal sexual health, highlighting the significance of promoting positive sexual values, improving physical fitness, and managing stress. Health care providers should educate, counsel, and collaborate interdisciplinarily, ensuring culturally sensitive care tailored to individual needs. STRENGTH AND LIMITATIONS: The study's strength lies in its provision of valuable insights into factors affecting sexual interest among postmenopausal Asian women, enhancing comprehension of holistic sexual health approaches. However, reliance on self-assessments may introduce response bias influenced by social desirability, and limited generalizability stems from single-site data collection. CONCLUSION: Our study highlights the significance of adopting a holistic approach to addressing sexual health in postmenopausal women, which includes promoting positive sexual values, improving physical fitness, and managing stress.

RESUMEN

Patients with hepatic failure are often accompanied by hepatic retinopathy, but the cellular and molecular mechanisms underlying the hepatic retinopathy remain unclear. In this study, we investigated how liver failure leads to hepatic retinopathy using bile duct ligation (BDL) rats as a cholestasis animal model. Light-dark box test was used to assess sensitivity to light, indexed as visual acuity. On D28 post-BDL, rats were subjected to light-dark box test and blood samples were collected for biochemical analyses. The rats then were euthanized. Liver, spleen and both side of eye were quickly harvested. We showed that BDL impaired rat sensitivity to light, significantly decreased the thickness of inner nuclear layer (INL), outer nuclear layer (ONL) and total retina, as well as the retinal cell numbers in ONL and ganglion cell layer (GCL). The expression of rhodopsin (RHO), brn-3a and GPX4 was significantly decreased in retina of BDL rats, whereas the expression of cleaved caspase 3, 8, 9, bax/bcl-2, RIP1, GFAP, and iba-1, as well as TUNEL-positive cells were significantly increased. In cultured retinal explant, we found that NH4Cl (0.2, 1, 5 mM) concentration-dependently impaired activity of retinal explant, decreased thickness of INL and ONL, downregulated expression of brn-3a, RHO and GFAP, increased expression of cl-caspase 3 and TUNEL-positive cell numbers, with NH4Cl (5 mM) almost completely disrupting the structure of the cultured retina; bilirubin (1 µM) significantly upregulated GFAP expression, whereas high level (10 µM) of bilirubin downregulated expression of GFAP. We further demonstrated in vivo that hyperammonemia impaired rat sensitivity to light, decreased thickness of INL and ONL, downregulated expression of RHO, brn-3a, GFAP and increased expression of cl-caspase 3; hyperbilirubinemia impaired rat sensitivity to light, upregulated expression of GFAP and iba-1. In conclusion, BDL impaired rat visual acuity due to the elevated levels of ammonia and bilirubin. Ammonia induced loss of retinal ganglion cells and rod photoreceptor cells via apoptosis-mediated cell death. Bilirubin impaired retinal function via activating microglia and Müller cells.

RESUMEN

Split-hand/foot malformation is a serious congenital limb malformation characterized by syndactyly and underdevelopment of the phalanges and metatarsals. In this study, we reported a case of a fetus with hand-foot cleft deformity. Whole exome and Sanger sequencing were used to filter out candidate gene mutation sites and provide pre-implantation genetic testing(PGT) for family members. Genetic testing results showed that there was a homozygous mutation c.786G>A (p.Trp262*) in the fetal WNT10B, and both parents were carriers of heterozygous mutations. PGT results showed that out of the two blastocysts, one was a heterozygous mutant and the other was a homozygous mutant. All the embryos had diploid chromosomes. The heterozygous embryo was transferred, and a singleton pregnancy was successfully achieved. This study suggests that homozygous mutations in WNT10B are the likely cause of hand-foot clefts in this family. For families with monogenic diseases, preimplantation genetic testing can effectively prevent the birth of an affected child only after identifying the pathogenic mutation.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Cooling Blood and Detoxicating Formular (CBDF) based on the theory of cooling blood and dosing detoxification, is a useful traditional Chinese medicine (TCM) medication for psoriasis with blood-heat syndrome. AIM OF THE STUDY: Investigate the active constituents and mechanisms of the CBDF for the treatment of psoriasis. MATERIALS AND METHODS: UPLC-Q-Orbitrap-HRMS technique was used to analyse the ingredients of CBDF absorbed into plasma and skin tissue. The therapeutic efficacy of CBDF was evaluated in treating an imiquimod (IMQ)-induced mouse model was assessed. Transcriptome analysis and gene enrichment analysis were used to explore the changes in gene expression and pathways following treatment with the CBDF. Validation was performed using western blotting, quantitative RT-PCR, flow cytometry, gene knockout and molecular docking in vitro and in vivo. RESULTS: 26 compounds were identified in the plasma of IMQ-induced psoriasis-like mouse with CBDF treatment, and higher levels of cimifugin in the lesion. CBDF improved the pathological changes of psoriasis, with inhibition of TNF-α, IL-23, and IL-17A and upregulation of IL-10. Gene enrichment analysis showed that the therapeutic effect of CBDF was related to AMPK pathway. In psoriasis lesions, the AMPK and fatty acid oxidation were suppressed, and glycolysis was enhanced. The Prkaa2, encoding AMPKα2 was down-regulated in psoriasis patients. CBDF inhibited glycolysis while stimulating fatty acid oxidation by the activating AMPK, thereby exerting an inhibitory effect on inflammation. CBDF inhibited MHCII, CD80, and CD86 on dendritic cells of skin drainage lymph node. In vitro, CBDF inhibited bone marrow-derived DCs secrete IL-23, TNF-α, and lactate, while enhanced fatty acid oxidation and AMPK activity. However, the therapeutic effect was weakened in AMPKα2 deletion. Additionally, psoriasis lesions and dendritic cells activation were significantly aggravated after AMPKα2 knockout. The key ingredients of the CBDF, cimifugin, rutin, astilbin, quercetin, and prim-O-glucosylcimifugin, all exhibit a notable affinity towards AMPKα2 binding. CONCLUSIONS: CBDF ameliorates psoriasis symptoms and inhibit dendritic cells maturation by regulating metabolic reprogramming in an AMPK-dependent mechanism.

RESUMEN

OBJECTIVE: Diminished ovarian reserve (DOR) encompasses both reproductive and endocrine disorders, resulting in a decline in female fertility. This paper explored the mechanism of Yangjing Zhongyu Decoction (YJZYD) regulating mitochondrial dynamics of ovarian granulosa cells (GCs) to improve DOR. METHODS: DOR patients were treated with YJZYD, with ovarian volume (OV), antral follicle count (AFC), and endometrial thickness (EMT) detected. C57BL/6 female mice were treated by cyclophosphamide (Cy) intraperitoneal injection and YJZYD solution daily gavage, with serum anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels determined. Ovarian GCs (KGN) were interfered with 4-Hydroperoxy-Cyclophosphamide (4-HC) and treated with the MAPK/ERK pathway inhibitor or activator. RESULTS: DOR patients showed increased levels of serum AMH, E2, OV, AFC and EMT, while reduced FSH and LH levels after YJZYD treatment. After Cy induction, DOR mice exhibited irregular estrous cycles, diminished serum AMH and E2 levels, elevated FSH and LH levels, reduced follicle number and atresia follicle number, disorderly arranged GCs, and severe interstitial fibrosis. After 4-HC treatment, KGN proliferation and Bcl-2, MFN1, and MFN2 were suppressed, while apoptotic rate, Bax, Cleaved-caspase-3, and p-Drp1 (Ser616) levels, and mitochondrial fission and quantity increased. YJZYD promoted 4-HC-treated KGN proliferation, boosted mitochondrial fusion, and inhibited apoptosis and mitochondrial fission via the MAPK/ERK pathway. CONCLUSION: YJZYD promoted ovarian GC proliferation and mitochondrial fusion, suppressed cell apoptosis and mitochondrial fission, and effectively improved DOR in mice by activating the MAPK/ERK pathway, providing a theoretical basis for the clinical application value of YJZYD in DOR treatment.

RESUMEN

The development of high-performance metal-free organic X-ray scintillators (OXSTs), characterized by a synergistic combination of robust X-ray absorption, efficient exciton utilization, and short luminescence lifetimes, poses a considerable challenge. Here we present an effective strategy for achieving augmented X-ray scintillation through the utilization of halogenated open-shell organic radical scintillators. Our experimental results demonstrate that the synthesized scintillators exhibit strong X-ray absorption derived from halogen atoms, display efficacious X-ray stability, and theoretically achieve 100% exciton utilization efficiency with a short lifetime (∼18 ns) due to spin-allowed doublet transitions. The superior X-ray scintillation performance exhibited by these organic radicals is not only exploitable in X-ray radiography for contrast imaging of various objects but also applicable in a medical high-resolution micro-computer-tomography system for the clear visualization of fibrous veins within a bamboo stick. Our study substantiates the promise of organic radicals as prospective candidates for OXSTs, offering valuable insights and a roadmap for the development of advanced organic radical scintillators geared towards achieving high-quality X-ray radiography.

RESUMEN

Tumorigenesis and metastasis are highly dependent on the interactions between the tumor and the surrounding microenvironment. In 3D matrix, the fibrous structure of the extracellular matrix (ECM) undergoes dynamic remodeling during tumor progression. In particular, during the late stage of tumor development, the fibers become more aggregated and oriented. However, it remains unclear how cancer cells respond to the organizational change of ECM fibers and exhibit distinct morphology and behavior. Here, we used electrospinning technology to fabricate biomimetic ECM with distinct fiber arrangements, which mimic the structural characteristics of normal or tumor tissues and found that aligned and oriented nanofibers induce cytoskeletal rearrangement to promote directed migration of cancer cells. Mechanistically, caveolin-1(Cav-1)-expressing cancer cells grown on aligned fibers exhibit increased integrin ß1 internalization and actin polymerization, which promoted stress fiber formation, focal adhesion dynamics and YAP activity, thereby accelerating the directional cell migration. In general, the linear fibrous structure of the ECM provides convenient tracks on which tumor cells can invade and migrate. Moreover, histological data from both mice and patients with tumors indicates that tumor tissue exhibits a greater abundance of isotropic ECM fibers compared to normal tissue. And Cav-1 downregulation can suppress cancer cells muscle invasion through the inhibition of YAP-dependent mechanotransduction. Taken together, our findings revealed the Cav-1 is indispensable for the cellular response to topological change of ECM, and that the Cav-1/YAP axis is an attractive target for inhibiting cancer cell directional migration which induced by linearization of ECM fibers.

RESUMEN

BACKGROUND: Depression presents significant challenges to mental health care. Although physical activity is highly beneficial to mental and physical health, relatively few studies have conducted on the relationship between them. AIM: To investigate the association between muscle quality index (MQI) and incidence of depression. METHODS: The data used in this cross-sectional study were obtained from the 2011-2014 National Health and Nutritional Examination Survey, which included information on MQI, depression, and confounding factors. Multivariable logistic regression models were employed, while taking into account the complex multi-stage sampling design. A restricted cubic spline model was utilized to investigate the non-linear relationship between the MQI and depression. Additionally, subgroup analyses were performed to identify influential factors. RESULTS: The prevalence of depression in this population was 8.44%. With the adjusted model, the MQI was associated with depression in females (odds ratio = 0.68, 95% confidence interval: 0.49-0.95) but not in males (odds ratio = 1.08, 95% confidence interval: 0.77-1.52). Restricted cubic spline adjustment of all covariates showed a significant negative non-linear relationship between depression and the MQI in females. The observed trend indicated an 80% decrease in the risk of depression for each unit increase in MQI, until a value of 2.2. Subsequently, when the MQI exceeded 2.2, the prevalence of depression increased by 20% for every unit increase in the MQI. Subgroup analyses further confirmed that the MQI was negatively associated with depression. CONCLUSION: The MQI was inversely correlated with depression in females but not males, suggesting that females with a higher MQI might decrease the risk of depression.

RESUMEN

Background: Cardiac rehabilitation is a beneficial multidisciplinary treatment of exercise promotion, patient education, risk factor management, and psychosocial counseling for people with coronary heart disease (CHD) that is underutilized due to substantial disparities in access, referral, and participation. Empirical studies suggest that cardiac telerehabilitation (CTR) have safety and efficacy comparable to traditional in-person cardiac rehabilitation, however, older adults are under-reported with effectiveness, feasibility, and usability remains unclear. Methods: The study randomized 43 older adults (84 % males) to the 12-week CTR intervention or standard of care. Guided by Social Cognitive Theory, participants received individualized in-person assessment and e-coaching sessions, followed by CTR usage at home. Data were collected at baseline (T0), six-week (T1), and 12-week (T2). Results: Participants in the CTR intervention group showed significant improvement in daily steps (T1: ß = 4126.58, p = 0.001; T2: ß = 5285, p = 0.01) and health-promoting lifestyle profile (T1: ß = 23.26, p < 0.001; T2: ß = 12.18, p = 0.008) across study endpoints. Twenty participants completed the intervention, with 40 % used the website for data-uploading or experiential learning, 90 % used the pedometer for tele-monitoring. Improving awareness of rehabilitation and an action focus were considered key facilitators while physical discomforts and difficulties in using the technology were described as the main barriers. Conclusions: The CTR is feasible, safe and effective in improving physical activity and healthy behaviors in older adults with CHD. Considering the variation in individual cardiovascular risk factors, full-scale RCT with a larger sample is needed to determine the effect of CTR on psychological symptoms, body weight and blood pressure, and quality of life.

RESUMEN

To examine the underlying determinants of ozone (O3) in Yinchuan's urban park during varying seasons and to ascertain the role played by meteorological events and air contaminants in influencing O3 concentrations at high altitudes, data on O3, meteorological factors, and air pollutants were collected through prolonged positional observations carried out at the Ningxia Yinchuan National Urban Ecosystem Research Station. Pearson correlation analysis and a structural equation model were utilized to investigate the spatio-temporal distribution patterns, trends, and the primary factors influencing O3. The findings demonstrated a notable seasonal variability in O3 levels in Yinchuan's urban park, displaying an "unimodal type" with the O3 concentration peaking in summer (131.18 µg·m-3) and bottoming out in winter (71.45 µg·m-3). Among the meteorological factors, the highest impact on O3 was attributed to temperature and wind speed (temperature mainly through direct effects and wind speed mainly through indirect effects). Conversely, air pollutants such as NOx and SO2 greatly affected O3 primarily through direct effects. Wind speed was identified as the primary influencing factor on O3 during spring and summer, potentially contributing 29% and 24.7%, respectively. Conversely, NO2 was implicated as the primary factor during autumn and winter, with an estimated contribution of 26.6% and 29.7%, respectively. Thus, a structural equation model can efficiently reveal the primary determinants behind O3 variations throughout various seasons, which could furnish a scientifically rigorous foundation and technical aid for mitigating and managing O3 levels in high-altitude regions.

RESUMEN

Organic materials with thermally activated delayed fluorescence (TADF) and room-temperature phosphorescence (RTP) dual emission have attracted great attention in recent years, but the regulation mechanism via internal and external heavy atoms is not clear enough. Here, we carry out a systematic theoretical investigation on the photophysical properties of the materials by introducing aliphatic or aromatic bromine atoms. The molecule with aromatic bromine atoms exhibits obvious TADF owing to the effective reverse intersystem crossing (RISC) with matchable energy levels and enhanced spin orbit couplings, the molecule with aliphatic bromine atoms shows a long RTP lifetime because of the reduced nonradiative transition of triplet excitons, and the molecule with both aliphatic and aromatic bromine atoms presents balanced TADF and RTP emissions thanks to the synergy internal and external heavy-atom effects. Besides, the internal and external heavy atoms induce multisite intermolecular interactions, effectively suppressing the nonradiative process in the solid phase. The efficient RISC process and the suppressed nonradiative process of triplet excitons should be key to regulating the dual emission property. These findings and insights are of great importance for revealing the structure-performance relationship, providing theoretical guidance for the design of TADF and RTP dual emission molecules via internal and external heavy-atom effects.

RESUMEN

The proton exchange membrane water electrolyzer (PEMWE) is one of the most promising electrochemical energy conversion devices for hydrogen production, while still limited by performance bottlenecks at high current densities, due to the lack of mass transfer insights. To investigate the mechanisms of oxygen transport inside the PEMWE at high current density and its relation to electrolytic performance. Operational in situ x-ray imaging is utilized to simultaneously characterize the bubble behavior and voltage response in a novel designed visual mini-cell, and it is identified that oxygen evolution and transport in the PEMWE follow the process of bubble nucleation, growth, and detachment. Based on the results of mini-cells with three porous transport layers (PTLs) up to 9 A cm-2 operation, it revealed that critical current densities exist for both carbon-based and titanium-based PTLs. Once exceeding the critical current density, the cell voltage can no longer be stabilized and the cell exhibits a significant oxygen overpotential. To illustrate this, the concept of interfacial separation zone (ISZ) is first proposed, which is an effective pathway for bubble growth and separation and the pattern of the ISZ exhibits specific regimes with the critical current density. Ultimately, a new approach for better understanding the mechanisms of oxygen transport is revealed.

RESUMEN

Brain metastases (BrMs) evade the immune response to develop in the brain, yet the mechanisms of BrM immune evasion remains unclear. This study shows that brain astrocytes induce the overexpression of neuronal-specific cyclin-dependent kinase 5 (Cdk5) in breast cancer-derived BrMs, which facilitates BrM outgrowth in mice. Cdk5-overexpressing BrMs exhibit reduced expression and function of the class I major histocompatibility complex (MHC-I) and antigen-presentation pathway, which are restored by inhibiting Cdk5 genetically or pharmacologically, as evidenced by single-cell RNA sequencing and functional studies. Mechanistically, Cdk5 suppresses MHC-I expression on the cancer cell membrane through the Irf2bp1-Stat1-importin α-Nlrc5 pathway, enabling BrMs to avoid recognition by T cells. Treatment with roscovitine-a clinically applicable Cdk5 inhibitor-alone or combined with immune checkpoint inhibitors, significantly reduces BrM burden and increases tumour-infiltrating functional CD8+ lymphocytes in mice. Thus, astrocyte-induced Cdk5 overexpression endorses BrM immune evasion, whereas therapeutically targeting Cdk5 markedly improves the efficacy of immune checkpoint inhibitors and inhibits BrM growth.

RESUMEN

INTRODUCTION AND OBJECTIVES: Significant fibrosis is an indicator of clinical intervention for both chronic hepatitis B (CHB) and metabolic dysfunction-associated steatotic liver disease (MASLD). There remains a paucity of data regarding the clinical impact of biopsy-defined MASLD on significant fibrosis in CHB patients. The current study aims to elucidate whether patients with concomitant MASLD are at higher risk of significant fibrosis in patients with CHB. PATIENTS AND METHODS: This retrospective research of two tertiary hospitals comprised 1818 patients between 2009 and 2021 with CHB and hepatic steatosis who had not received antiviral therapy. Pathologic findings by liver biopsy were contrasted between CHB group (n = 844) and CHB + MASLD (n = 974) group. METAVIR values of F≥2 were used to categorize significant fibrosis. RESULTS: Patients with CHB + MASLD had more significant fibrosis (35.5 % vs. 23.5 %, p < 0.001) than CHB group. The presence of MASLD [adjusted odds ratio (aOR) 2.055, 95 % confidence interval (CI) 1.635-2.584; p < 0.001] was strongly associated with significant fibrosis in all CHB patients. There was a trend for patients with more cardiometabolic risk factors (CMRFs) to have a higher prevalence of significant fibrosis:(25.7 % in CMRF1 subgroup v.s. 34.9 % in CMRF2 subgroup v.s. 53.7 % in CMRF≥ 3 subgroup, p < 0.001). Patients with CMRF≥3 had a three-fold higher significant fibrosis than those with just one CMRF. CONCLUSIONS: MASLD was associated with higher fibrosis stage in patients with CHB. Early detection and intervention are crucial to patients with three or more cardiometabolic risk factors.

RESUMEN

Background: Globally, early-life adversity (ELA) is linked to an increased risk of developing depression in adulthood; however, only a few studies have examined the specific effects of various types of ELA on depression in children and adolescents. This meta-analysis explores the association between the subtypes of ELA and the risk for youth-onset depression. Methods: We searched three electronic databases for reporting types of ELA, namely, emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, family conflict/violence, divorce, low socioeconomic status, and left-behind experience, associated with depression before the age of 18 years. Our meta-analysis utilized the odds ratio (OR) and relied on a random effects model. Large heterogeneous effects were detected. Some factors moderated the association between ELA and depression in youths. The homogeneity of variance test and meta-regression analysis were used to detect these relationships. Results: A total of 87 studies with 213,006 participants were ultimately identified via several strategies in this meta-analysis. Individuals who experienced ELA were more likely to develop depression before the age of 18 years old than those without a history of ELA (OR=2.14; 95% CI [1.93, 2.37]). The results of the subgroup analysis revealed a strong association between ELA and depression in youth, both in terms of specific types and dimensions. Specifically, emotional abuse (OR = 4.25, 95% CI [3.04, 5.94]) was more strongly related to depression in children and adolescents than other forms of ELA were. For both dimensions, threat (OR = 2.60, 95% CI [2.23, 3.02]) was more closely related to depression than deprivation was (OR = 1.76, 95% CI [1.55, 1.99]). Conclusion: This meta-analysis revealed that the adverse effects of a broader consideration of ELA on the risk of youth-onset depression vary according to the subtypes of ELA.

RESUMEN

Background: Acupuncture is popular in the treatment of mental illness. This study determined its feasibility and role in managing postpartum depression (PPD) using a network meta-analysis. Methods: We systematically searched seven databases up to May 2024 for randomized controlled trials (RCTs) appraising acupuncture's efficacy and safety against waitlist-control, placebo, standard control, or as an add-on treatment. Cochrane criteria were followed. Results: Thirteen studies encompassing 872 participants underwent analysis. Both pairwise and network meta-analysis indicated that acupuncture, psychotherapy, and antidepressants were comparable in clinical efficacy rate and in reducing Hamilton Depression Scale and Edinburgh Postnatal Depression Scale scores. Acupuncture and psychotherapy also effectively mitigated concurrent anxiety symptoms. Combining acupuncture with antidepressants augmented therapeutic efficacy and reduced reported gastrointestinal adverse effects associated with antidepressant use. Acupuncture combined with psychotherapy offered similar benefits with superior safety profile. However, the quality of evidence ranged from very low to low due to significant risks of bias and limited sample sizes. The efficacy of psychotherapy and the combination of acupuncture and psychotherapy might be underestimated, as most RCTs used supportive therapy or individual counseling as positive controls instead of recommended approaches like interpersonal psychotherapy (IPT) or cognitive behavioral therapy (CBT) per PPD guidelines. Conclusion: Current evidence precludes strong recommendations of administering acupuncture in PPD. Rigorous RCTs are essential to validate promising outcomes observed in comparisons between acupuncture, antidepressants, and their combined application. It remains inconclusive whether acupuncture's antidepressive effect is specific or non-specific. Given that psychotherapy is a recommended first-line treatment, investigating the potential efficacy enhancement of combining acupuncture with IPT/CBT is paramount to ascertain the preferred therapeutic approach for PPD.

RESUMEN

Despite their ban, polybrominated diphenyl ethers (PBDEs) are frequently detected in various environmental compartments including marine and coastal ecosystems due to their persistence, bio-accumulative, high production volumes, and widespread use. One of the major concerns from PBDEs is the transformation products, such as hydroxylated polybrominated diphenyl ethers (OH-BDEs), which are more bioactive than the parent compounds. For example, 6-hydroxy-2,2',4',4-tetrabromodiphenyl ether (6-OH-BDE-47) is a typical metabolite of PBDEs and cause endocrine system disruption, developmental toxicity, and neurotoxicity in different species. Despite being widely detected in marine environments, investigations on the toxicological mechanisms of 6-OH-BDE-47 in cetaceans remain scarce. High concentrations of PBDEs accumulate in cetaceans due to the long lifespan and large fat reserve. The accumulated PBDEs have become the major source of OH-BDEs in cetaceans. We exposed immortalized fibroblast cell lines from the skin of pygmy killer whales (PKW-LWHT) and Indo-Pacific finless porpoises (FP-LWHT) to 6-OH-BDE-47 and analyzed changes in cellular function using transcriptomic data, along with enzymatic activity. Exposure to the body-relevant body burdens of 6-OH-BDE-47 (250 and 500 ng mL-1) significantly decreased cell viability. Differentially expressed genes in FP-LWHT exposed to 6-OH-BDE-47 were primarily enriched in the pathways associated with steroid metabolism. Total cholesterol was decreased by 6-OH-BDE-47, whereas low-density lipoprotein cholesterol and triglyceride levels were significantly increased in FP-LWHT cells. In contrast, glycolysis was the main enriched function of differentially expressed genes in PKW-LWHT cells exposed to 6-OH-BDE-47, and the enzyme activity of phosphofructokinase and hexokinase was upregulated. Thus, even though the cell viability of both cell lines from these two species was significantly suppressed by 6-OH-BDE-47, the cellular response or affected cellular function was different between the Pygmy killer whale and the Indo-Pacific Finless Porpoise, suggesting a diverse response towards OH-BDEs exposure.

RESUMEN

BACKGROUND: The purpose of this study was to investigate the effect of folic acid (FA) and vitamin D supplementation on increasing maternal serum folate and 25-hydroxyvitamin D [25(OH)D] concentrations during pregnancy and further reveal its role in reducing the risk of fetal growth restriction (FGR) in patients with preeclampsia (PE). METHODS: A total of 300 preeclamptic patients (treatment group 204 and control group 96) who had undergone routine obstetric examinations were retrospectively analyzed in this study. Data that include maternal serum levels of folate and 25(OH)D detected during early, middle, and late gestational periods from the medical records were analyzed. Multifactorial logistic regression analysis was performed to investigate the correlation of serum folate and 25(OH)D concentrations with the incidence of FGR. RESULTS: Serum folate and 25(OH)D concentrations were similar between the treatment group and control group in the early gestation. During the middle and late gestation, the serum folate and 25(OH)D levels were both continuously increased in the treatment group, but persistently decreased in the control group, leading to significant differences between the two groups (p < .001). In addition, the incidence of FGR was significantly lower in the treatment group than in the control group (p < .001). Logistic regression analysis showed significant correlations of increased serum folate and 25(OH)D levels with lower risk of FGR. CONCLUSIONS: FA and vitamin D supplementations facilitated to lower the risk of FGR in preeclamptic patients. These results would be the solid foundation for the further investigation of approaches to improve adverse outcomes of pregnancy, and have potential guiding implications for clinical practice.

RESUMEN

Anionic nido-carboranes, as open-cage analogues of closo-carboranes with strong hydrophilicity and higher potential in the development of biomedicines, have been notably more challenging because of their strong interaction with transition metals. While the exo-cage B-H activation reactions of nido-carboranes have been widely studied, there are few reports on the direct functionalization of B-H bonds located on a closed polyhedral sphere. Here, we report an efficient palladium-catalyzed regioselective B(2/3)-H alkenylation of nido-carboranes with various alkenes and alkyne coupling partners, enabled by 3-methylpyridine directing groups, to achieve a regiocontrollable functionalization of B(2/3)-H vertices over highly reactive exo-cage B11-H vertex in nido-carboranes.
