The role of TERT C228T and KDM6A alterations and TME in NMIBC treated with BCG.

We aimed to investigate the genomic and tumor microenvironmental (TME) profiles in non-muscle invasive bladder cancer (NMIBC) and explore potential predictive markers for Bacillus Calmette-Guérin (BCG) treatment response in high-risk NMIBC patients (according to European Association of Urology (EAU) risk stratification). 40 patients with high-risk NMIBC (cTis-T1N0M0) who underwent en bloc resection followed by BCG instillation were retrospectively enrolled. Surgical samples were subjected to Next Generation Sequencing (NGS) and multiplex immunofluorescence (mIF) assay. Genomic profiling revealed high prevalences of alterations in TERT (55%), KDM6A (32.5%), FGFR3(30%), PIK3CA (30%), TP53(27.5%) and ARID1A (20%). TME analysis showed different proportions of macrophages, NK cells, T cells subsets in tumoral and stromal compartment. Multivariate analysis identified TERT C228T and alteration in KDM6A as two independent factors associated with inferior RFS. The study comprehensively depicted the genomic and TME profiles in NMIBC and identified potential predictive biomarkers for BCG treatment.

Xiaobugan decoction prevents CCl4-induced acute liver injury by modulating gut microbiota and hepatic metabolism.

BACKGROUND: The liver plays a crucial role in detoxification and metabolism. When its capacity to metabolize foreign substances is exceeded, it can lead to acute liver injury (ALI). Therefore, preventing liver disease and maintaining daily liver health are of utmost importance. Xiaobugan Decoction (XBGD), a traditional Chinese medicine (TCM) formula, is recorded in 'Fuxingjue', is used in folk practice to promote liver health and regulate respiration. However, the hepatoprotective mechanisms of XBGD remained unclear. PURPOSE: We investigated the prophylactic and hepatoprotective effects of XBGD and explored its related molecular mechanisms using a mouse model of carbon tetrachloride (CCl4)-induced ALI. STUDY DESIGN AND METHODS: XBGD composition was determined using analytical methods, and the main compounds were identified using ultra-high-performance liquid chromatography coupled with Q-Exactive focus mass spectrum (UHPLC-QE-MS) and high-performance liquid chromatography (HPLC). A CCl4-induced L02 cell injury model was employed to explore the protective effects of XBGD on liver cells, and a CCl4-induced ALI mouse model was used to investigate the hepatoprotective effects of XBGD. RESULTS: Cellular experiments demonstrated that XBGD had a protective function against L02 cell damage by increasing cell viability, restoring alanine aminotransferase (ALT), aspartate aminotransferase (AST), and superoxide dismutase (SOD) levels, reducing malondialdehyde (MDA) content, and improving mitochondrial membrane potential (ΔΨm). In the mouse ALI model, XBGD prevented ALI by reducing ALT, AST, and alkaline phosphatase (ALP) levels and inhibiting oxidative stress. Quantitative real-time polymerase chain reaction (qPCR), immumohistochemical staining and western blotting results revealed that XBGD exerted hepatoprotective effects by reducing inflammatory responses and inhibiting cell apoptosis. Furthermore, 1H-NMR metabolomics indicated that XBGD regulates hepatic and intestinal metabolism, whereas 16S rDNA sequencing demonstrated the regulatory effects of XBGD on the gut microbiota. Correlation analysis highlighted the close relationship among gut microbiota, metabolites, and ALI indicators. CONCLUSIONS: XBGD is a promising TCM for the prevention of CCl4-induced ALI via regulation of microbiota and metabolism. This study provides a new perspective on the development of hepatoprotective measures and the prevention of liver disease in daily life.

Degradation characteristics and effect mechanisms of estrogens during aerobic composting of chicken manure based on the orthogonal test.

Environmental estrogens are currently a significant research topic, and poultry manure serves as a crucial source. This study investigated the degradation characteristics and effect mechanisms of six estrogens (E1, 17α-E2, 17ß-E2, E3, 17α-EE2, and DES) during the aerobic composting of chicken manure. An orthogonal test comprising four factors (aeration rate, calcium-magnesium-phosphorus fertilizer (Ca-Mg-P fertilizer), coconut shell biochar, initial moisture content) and three levels of aerobic composting was conducted over a 45-day period to monitor the changes in estrogens and basic parameters. The results indicated that the factors influencing the estrogen degradation rate ranked as: initial moisture content (MC) > Ca-Mg-P fertilizer > aeration rate > coconut shell biochar. These factors significantly influenced the abundance of estrogen-degrading genera. Optimal composting conditions for estrogen degradation were identified as the addition of 10% coconut shell biochar, maintaining an initial moisture content of 60%, and using an aeration rate of 0.08 L min-1∙kg-1DM (dry matter), with an average degradation rate of 86.88% for the six estrogens under these conditions. During the composting process under various treatments, five known estrogen-degrading genera were observed with high relative abundance (max 31.08%), and the predominant genera were Staphylococcus and Brachybacterium for 17α-E2, 17ß-E2, E3, 17α-EE2, and DES, and Pusillimonas for E1. The composition of microbial community structure changed significantly, and the dominated environment factors effecting the composition and succession of these genera were carbon to nitrogen ratio (C/N) and MC. The research results can provide both a theoretical basis and practical reference for the effective degradation of estrogens during the composting of chicken manure.

Lauric acid improved the quality of fresh noodles with/without sodium bicarbonate by altering physical properties and structure of wheat starch.

To know the influence of lauric acid (LA) on wheat flour fresh noodles (WFN) quality and the latent mechanism, the effect of LA on cooking properties, digestibility and structure of WFN with/without sodium bicarbonate (SB) and the properties of wheat flour (WF) with/without SB were studied. The results indicated that LA reduced cooking loss and digestibility of WFN with SB and slightly decreased water adsorption and increased the free water binding ability and hardness of WFN without SB. Furthermore, LA increased the degree of short- and long-range order and molecular weight of starch in cooked WFN with/without SB and it had greater effect on the degree of short- and long-range order and molecular weight of starch in cooked WFN with SB than that without SB. Differential scanning calorimeter (DSC) and rapid viscosity analysis (RVA) displayed that WFN with LA and SB formed more starch-LA or/and starch-LA-protein complexes than WFN with LA. Additionally, the impact of LA on WFN quality and WF properties was influenced by SB concentration. This study will provide theoretical basis and new thoughts for the design of high-quality fresh noodles with low digestibility, low cooking loss and high hardness.

WTAP weakens oxaliplatin chemosensitivity of colorectal cancer by preventing PANoptosis.

As the most abundant post-transcriptional modification in eukaryotes, N6-methyladenosine (m6A) plays a crucial role in cancer cell proliferation, invasion and chemoresistance. However, its specific effects on chemosensitivity to oxaliplatin-based regimens and the impact of these drugs on m6A methylation levels in colorectal cancer (CRC) remain largely unexplored. In this study, we demonstrated that the m6A methyltransferase Wilms tumor 1-associating protein (WTAP) weakens oxaliplatin chemosensitivity in HCT116 and DLD1 cells. Mechanistically, oxaliplatin treatment upregulated WTAP expression, preventing multiple forms of cell death simultaneously, a process known as PANoptosis, by decreasing intracellular oxidative stress through maintaining the expression of nuclear factor erythroid-2-related factor 2 (NRF2), a major antioxidant response element, in an m6A-dependent manner. In addition, high WTAP expression in CRC patients is associated with a poor prognosis and reduced benefit from standard chemotherapy by clinical data analysis of The Cancer Genome Atlas (TCGA) database and patient cohort study. These findings suggest that targeting WTAP-NRF2-PANoptosis axis could enhance the antitumor efficacy of oxaliplatin-based chemotherapy in CRC treatment.

Trend and driving factors in burden of age-related macular degeneration in older adults aged 60-89 years: a global analysis over three decades.

BACKGROUND: To explore temporal trends and determine driving factors of age-related macular degeneration (AMD) burden in older adults aged 60-89 years at global, regional and national levels from 1990 to 2019. METHODS: Prevalence and years lived with disability (YLDs) were extracted. Joinpoint regression analysis was adopted to calculate average annual percentage change and to identify the year with the most significant changes. Global trends were stratified by sex, age and sociodemographic index, and regional and national trends were explored. Decomposition analysis was conducted to determine what extent the forces of population size, age structure and epidemiologic change driving alterations of AMD burden. RESULTS: Globally, prevalence rate slightly increased whereas YLDs rate decreased. The year 2005 marked a turning point where both prevalence and YLDs started to decline. Regionally, Western Sub-Saharan Africa had the highest prevalence and YLDs rates in 2019, with East Asia experiencing the most notable rise in prevalence from 1990 to 2019. Global decomposition revealed that the increased case number was primarily driven by population growth and ageing, and epidemiological change was only detected to lessen but far from offset these impacts. CONCLUSIONS: Although there was only slight increase or even decrease in prevalence and YLDs rates of AMD in older adults, the case number still nearly doubled, which may be primarily attributed to population growth and ageing, coupled with the emerging growing pattern of prevalence rate from 2015, collectively suggesting a huge challenge in control and management of AMD.

Treatment effect of ultra-pulse dynamic CO2 laser and comedone extractor in dense comedones: a prospective, randomized, split-face, evaluator-blind, controlled clinical trial.

Clearance of comedone is challenging in the treatment of acne, as it is very likely to develop into inflammatory lesions. However, there is lack of effective treatments for dense comedones. Comedone extractor has been widely employed by dermatologists, but the effect is temporary and may cause irritation. CO2 laser is a potential method for dense comedones, but the efficacy and safety need to be explored. In this single-center, randomized, single-blind, self-controlled study, the faces of patients with dense comedones were randomly assigned into two sides receiving either ultra-pulse dynamic CO2 laser or comedone extraction at an interval of 2 weeks for 4 sessions. After 4 treatments, the average comedone reduction rate of the CO2 laser was 64.49%, which was higher than that by the extractor (46.36%) (P < .001). 79.16% of the patients reached over 50% reduction by CO2 laser, while only 37.5% on extractor treated side reached 50% clearance. Texture index, porphyrin index, red zone, erythema index, and transepidermal water loss decreased after both treatments, and CO2 laser showed more improvement. There was no difference in hydration index and melanin index between the two treatments. No permanent or severe side effects were observed on both sides. The CO2 laser showed higher comedone clearance with lower pain scores than the comedone extractor.

Polystyrene microplastics alleviate the developmental toxicity of silver nanoparticles in embryo-larval zebrafish (Danio rerio) at the transcriptomic level.

Since silver nanoparticles (AgNPs) and polystyrene microplastics (PS-MP) share common environmental niches, their interactions can modulate their hazard impacts. Herein, we assessed the developmental toxicity of 1 mg/L PS-MP, 0.5 mg/L AgNPs and the mixtures of AgNPs and PS-MP on embryo-larval zebrafish. We found that AgNPs co-exposure with PS-MP remarkably decreased mortality rates, malformation rates, heart rates and yolk sac area, while it increased hatching rates and eye size compared to the AgNPs group. These phenomena revealed that the cell cycle, oxidative stress, apoptosis, lipid metabolism, ferroptosis and p53 signalling pathway were obviously affected by single AgNPs exposure at 96 hpf (hours post fertilization). Interestingly, all these effects were effectively ameliorated by co-exposure with PS-MP. The combination of transcriptomic and metabolomic analyses showed that the imbalance of DEGs (differentially expressed genes) and DEMs (differentially expressed metabolites) (PI, phosphatidylinositol and TAG-FA, triacylglycerol-fatty acid) disturbed both the cell cycle and lipid metabolism following single AgNPs exposure and co-exposure with PS-MP. These findings suggest that PS-MP attenuates the developmental toxicity of AgNPs on embryo-larval zebrafish. Overall, this study provides important insight into understanding the transcriptional responses and mechanisms of AgNPs alone or in combination with PS-MPs on embryo-larval zebrafish, providing a reference for ecological risk assessment of combined exposure to PS-MP and metal nanoparticles.

Analysis of the potential profile and influencing factors for oral frailty in olderly patients with dental implants.

OBJECTIVE: To investigate the current state of oral frailty in oldely patients with require dental implants, analyze influencing factors in the characteristics of oral frailty across different patient categories, and provide a reference for clinical staff to identify high-risk groups and develop proactive management strategies. METHODS: Between January 2024 and March 2024, 654 patients with dental implants were selected using convenience sampling from six secondary and tertiary stomatological hospitals in Jiangsu and Zhejiang provinces. Data were collected via a general information questionnaire and the Oral Frailty Index-8. The latent profiles of oral frailty were examined, and univariate and Logistic regression analyses were conducted to determine the impact of various factors on these profiles. RESULTS: In this cross-sectional study, 605 valid questionnaires were returned, yielding an effective rate of 92.58%. The mean oral frailty score was 6.64 ± 1.21, with the sample comprising 223 males and 382 females, averaging 72.54 ± 6.33 years old. Oral frailty was categorized into three latent profiles: high (20.50%), moderate (53.72%), and low (25.78%) frailty groups. Factor analysis indicated that age, gender, education level, family income, number of implants, and dyslipidemia significantly predicted the classification of these profiles (P < 0.05). CONCLUSION: Oral frailty in oldely patients with dental implants exhibits heterogeneity and is influenced by age, sex, education level, family income, number of implants, and dyslipidemia. Clinical staff should recognize the characteristics of different patient categories and implement proactive measures for those at high risk of oral frailty to enhance their quality of life.

Endothelial epoxyeicosatrienoic acid release is intact in aldosterone excess.

BACKGROUND AND AIMS: Endothelial dysfunction (ED) is considered to be a major driver of the increased incidence of cardiovascular disease in primary aldosteronism (PA). The functionality of the epoxyeicosatrienoic acid (EET) pathway, involving the release of beneficial endothelium-derived lipid mediators, in PA is unknown. Evidence suggests this pathway to be disturbed in various models of experimental hypertension. We therefore assessed EET production in primary human coronary artery endothelial cells exposed to aldosterone excess and measured circulating EET in patients with PA. METHODS: We used qPCR to investigate changes in the expression levels of essential genes for the synthesis and degradation of EET, calcium imaging to address the functional impact on overall endothelial function, as well as mass spectrometry to determine endothelial synthetic capacity to release EET upon stimulation. RNA-seq was performed to gain further mechanistic insights. Eicosanoid concentrations in patient's plasma were also determined by mass spectrometry. RESULTS: Aldosterone, while eliciting proinflammatory VCAM1 expression and disturbed calcium response to acetylcholine, did not negatively affect stimulated release of endothelial EET. Likewise, no differences were observed in eicosanoid concentrations in plasma from patients with PA when compared to essential hypertensive controls. However, an inhibitor of soluble epoxide hydrolase abrogated aldosterone-mediated VCAM1 induction and led to a normalized endothelial calcium response probably by restoring expression of CHRNE. CONCLUSION: EET release appears intact despite aldosterone excess. Epoxide hydrolase inhibition may revert aldosterone-induced functional changes in endothelial cells. These findings indicate a potential new therapeutic principle to address ED, which should be explored in future preclinical and clinical trials.

Detailed analysis of learning phases and outcomes in robotic and endoscopic thyroidectomy.

BACKGROUND: Thyroid surgery has undergone significant transformation with the introduction of minimally invasive techniques, particularly robotic and endoscopic thyroidectomy. These advancements offer improved precision and faster recovery but also present unique challenges. This study aims to compare the learning curves, operational efficiencies, and patient outcomes of robotic versus endoscopic thyroidectomy. METHODS: A retrospective cohort study was conducted, analyzing 258 robotic (da Vinci) and 214 endoscopic thyroidectomy cases. Key metrics such as operation duration, drainage volume, lymph node dissection outcomes, and hypoparathyroidism incidence were assessed to understand surgical learning curves and efficiency. RESULTS: Robotic thyroidectomy showed a longer learning curve with initially longer operation times and higher drainage volumes but superior lymph node dissection outcomes. Both techniques were safe, with no permanent hypoparathyroidism or recurrent laryngeal nerve damage reported. The study delineated four distinct stages in the robotic and endoscopic surgery learning curve, each marked by specific improvements in proficiency. Endoscopic thyroidectomy displayed a shorter learning curve, leading to quicker operational efficiency gains. CONCLUSION: Robotic and endoscopic thyroidectomies are viable minimally invasive approaches, each with its learning curves and efficiency metrics. Despite initial challenges and a longer learning period for robotic surgery, its benefits in complex dissections may justify specialized training. Structured training programs tailored to each technique are crucial for improving outcomes and efficiency. Future research should focus on optimizing training protocols and increasing accessibility to these technologies, enhancing patient care in thyroid surgery.

Construction and verification of a risk prediction model for cognitive frailty in older patients with chronic obstructive pulmonary disease and diabetes mellitus.

OBJECTIVE: We explored risk factors for cognitive frailty in older patients with chronic obstructive pulmonary disease (COPD) and diabetes mellitus to develop and verify a risk prediction model for cognitive frailty. METHODS: This was a cross-sectional study. Convenience sampling was used to randomly select 378 patients hospitalized between February 2022 and December 2023. We allocated 265 patients who visited between February 2022 and February 2023 to a modeling group to analyze risk factors for cognitive frailty and create a logistic regression model for risk prediction. Another 113 patients who visited between March 2023 and December 2023 were included in a validation group for model verification. RESULTS: The cognitive frailty incidence in the 265 patients was 35.09% (93/265). Regression analysis showed that age >80 years (odds ratio [OR] = 4.576), regular exercise (OR = 0.390, polypharmacy (OR = 3.074), depression (OR = 2.395) duration of COPD combined with diabetes (OR = 1.902), Family APGAR index score (OR = 0.428), and chronic pain (OR = 2.156) were factors influencing the occurrence of cognitive frailty in older patients with COPD accompanied by diabetes. CONCLUSIONS: The constructed risk prediction model for cognitive frailty in older patients with COPD and diabetes showed good predictive value, aiding in the clinical identification of high-risk patients and facilitating timely intervention and guidance.

[Retracted] Salidroside mitigates hypoxia/reoxygenation injury by alleviating endoplasmic reticulum stress­induced apoptosis in H9c2 cardiomyocytes.

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that certain of the cell apoptotic assay data shown in Fig. 1D on p. 3763 were strikingly similar to data that had already been submitted for publication in Fig. 3A in different form in another article written by different authors at different research institutes. Owing to the fact that the contentious data in the above article had already been submitted for publication prior to its submission to Molecular Medicine Reports, the Editor has decided that this paper should be retracted from the Journal. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a reply. The Editor apologizes to the readership for any inconvenience caused.

Acute Aerobic Exercise Intensity on Working Memory and Vigilance After Nap Deprivation: Effects of Low-Intensity Deserve Attention.

Background: Napping deprivation in habitual nappers leads to cognitive impairment. The ameliorative effect of acute aerobic exercise has been demonstrated for this post-cognitive impairment. However, it is still unclear which intensity of aerobic exercise is the most effective and how long this improvement can be sustained. Methods: Fifty-eight healthy adults with a chronic napping habit were randomly assigned to four intervention groups after undergoing nap deprivation: a sedentary control group, a low-intensity exercise group (50-59% maximum heart rate, HRmax), a moderate-intensity exercise group (60-69% HRmax), and a high-intensity exercise group (70-79% HRmax). Working memory (N-back task), vigilance (Psychomotor Vigilance Task, PVT), and response inhibitory capacity (Go/NoGo task) were measured. Results: Regression analyses showed a quadratic trend between exercise intensity and working memory reaction time and accuracy (F =3.297-5.769, p < 0.05, R2 =10.7-18.9%). The effects of exercise were optimal at low-intensity. There was a significant quadratic trend between exercise intensity and PVT lapse (F =4.314, p =0.042, R² =7.2%). The effect of exercise increased with higher intensity. Prolonged observation found that the effect of low-intensity exercise on working memory was maintained for 2 hours. Conclusion: The effect of low-intensity exercise might be underestimated. Low-intensity exercise significantly improved working memory performance, and the effects could be maintained throughout the afternoon. In contrast, the effects of high-intensity exercise were unlikely to be maintained and might even have negative effects. Future researchers can broaden the categories of participants to enhance the external validity and collect diverse physiological indicators to explore related physiological mechanisms.

[Pollution Characteristics, Source Analysis, and Health Risk Assessment of Heavy Metals in Soil and Crops in a Typical molybdenum Mining Area of Qinling Mountains].

This study focused on a molybdenum mining area in the Qinling Mountains （Shaanxi segment）. Crop and corresponding soil samples were collected from the vicinity of the mining area, and the concentrations of six heavy metals （Cr, Cu, Zn, As, Cd, and Pb） were determined. Soil heavy metal pollution was assessed using single-factor, comprehensive pollution, and geo-accumulation index methods. The primary sources of soil heavy metals were analyzed using the PMF model. A health risk assessment for soil and crops was conducted using the USEPA model. The results revealed severe pollution of agricultural soils by Cr, Cu, Zn, Cd, and Pb. Among these, Cr may have been primarily sourced from chrombismite nearby mining activities, contributing to 85.1% of the pollution. Cu and As were mainly sourced from agriculture, contributing 50.3% and 70.6%, respectively. Zn and Cd were primarily sourced from natural sources such as metal slag dust and rainwash from the mining area, contributing 73.5% and 48.7%, respectively. Pb was primarily sourced from transportation sources, contributing to 54.7% of the pollution. Crop metal contamination was especially severe for Cr, followed by Pb, whereas As and Cd contamination was relatively lower. Crops were significantly impacted by heavy metal pollution in agricultural soils. The health risk assessment indicated non-carcinogenic and carcinogenic risks for children due to soil heavy metals, whereas adults faced acceptable levels of risk. Both adults and children were exposed to highly significant non-carcinogenic and carcinogenic risks from heavy metals in the crops. Moreover, it is essential to implement effective measures to control heavy metal pollution from tailings to safeguard nearby residents, especially children, from adverse health risks.

Aspiration catheter tip flutter is a reliable indicator of successful clot aspiration in ADAPT.

BACKGROUND: A direct aspiration first pass technique (ADAPT) has emerged as a fast, safe, and efficacious method for treating acute large vessel occlusion. However, successful clot aspiration is not guaranteed in every ADAPT procedure. We have observed that when the catheter effectively ingested the clot, the catheter tip displayed a distinct fluttering motion, referred to herein as tip flutter. Thus this study aimed to assess whether this catheter tip flutter can be used as a sign of successful clot aspiration. METHODS: This retrospective study included 231 consecutive patients admitted to our institution due to acute ischemic stroke and treated with ADAPT between October 2018 and November 2023. We obtained baseline and procedural data from all patients. Additionally, we assessed the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy of the tip flutter in predicting clot aspiration. RESULTS: The incidence of embolus translocation was significantly higher in the tip flutter positive group than in the tip flutter negative group (P<0.001). Also, hyperdense artery presentation was more prevalent in the positive group (P<0.001), whereas the clot burden score was higher in the negative group (P=0.002). Clot aspiration in the first pass occurred in 83 (96.5%) and 37 (25.5%) patients in the positive and negative groups, respectively (P<0.001). Multivariable logistic regression analysis showed the tip flutter sign (OR 1.09, 95% CI 0.16 to 1.29; P<0.001) was an independent predictor of successful clot aspiration. Sensitivity, specificity, PPV, NPV, and accuracy of the tip flutter for predicting clot aspiration were 69.2%, 97.3%, 96.5 %, 74.5%, and 82.7%, respectively. CONCLUSIONS: In this study, we found that tip flutter was a reliable indicator of successful clot aspiration during ADAPT.

Relationship between postpartum psychological disorders and emotion regulation strategies: A cross-sectional study.

To explore the relationship between postpartum psychological disorders and emotion regulation strategies and analyze the influencing factors of postpartum psychological disorders. This study was conducted using a cross-sectional design. A total of 230 postpartum women hospitalized in the Second Affiliated Hospital of Xuzhou Medical University from October 2022 to March 2023 were selected as the investigation objects. A general data questionnaire, Hamilton Anxiety Scale, Hamilton Depression Scale, Pittsburgh Sleep Quality Index, and Emotion Regulation Questionnaire were administered to the enrolled women. Pearson correlation analysis was used to assess the association between the Hamilton Anxiety Scale, Hamilton Depression Scale, Pittsburgh Sleep Quality Index, and Emotion Regulation Questionnaire. Furthermore, logistic regression was employed to assess the influencing factors of postpartum psychological disorders. Pearson correlation analysis showed that cognitive reappraisal was negatively correlated and expression inhibition was positively associated with anxiety, depression, and sleep quality symptoms (all P < .05). Logistic regression results demonstrated that the mode of delivery, number of births, feeding method, and pressure to breastfeed were risk factors affecting postpartum psychological disorders (P < .05). Cognitive reappraisal is an effective emotion regulation strategy that can relieve postpartum psycho-neurological symptoms by reducing the symptoms of anxiety, depression, and sleep disorders. Along with encouraging pregnant women to adopt positive emotional regulation strategies, medical personnel should focus on the stress associated with cesarean section, artificial feeding, and pressure to breastfeed and adopt required intervention measures to decrease the occurrence of postpartum psychological and neurological symptoms.

A clinical evaluation of robotic-assisted radical prostatectomy (RARP) in located prostate cancer: A systematic review and network meta-analysis.

Prostate cancer (PCa) is a prevalent malignant tumor affecting the male reproductive system and there are mainly three widely accepted PCa surgery types in current clinical treatment: open radical prostatectomy (ORP), laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RARP). Here, we aimed to evaluate the clinical effect of RARP for PCa patients compared with ORP and LRP based on the context of PCa encompass two dimensions: oncological outcomes (biochemical recurrence (BCR) and positive surgical margin (PSM)) and functional outcomes (urinary continence and recovery of erectile function) in this network meta-analysis (NMA). PubMed, Embase and Cochrane databases were systematically searched in January 7, 2024. 4 randomized controlled trials (RCTs) and 72 non-RCTs were included. RARP displayed significant positive effect on lower BCR and better recovery of erectile function but no significant differences existed among three surgery types for PSM and urinary continence.

Enhancing the color and astringency of red wines through white grape seeds addition: Repurposing wine production byproducts.

The clear juice fermentation technique for white wines suggests that white grape seeds, rich in flavan-3-ols and proanthocyanidins, are not effectively utilized in the winemaking process. This study incorporated 'Gewürztraminer' grape seeds into 'Cabernet Sauvignon' must before cold soak to investigate how the resultant red wines' phenolic compound profiles, color, and astringency were affected. The results showed that adding seeds primarily inhibited the leaching of flavan-3-ols from both skins and seeds. A significant increase in the levels of flavan-3-ols, tannins, and phenolic acids, as well as direct and aldehyde-bridged flavan-3-ol-anthocyanin polymers, were observed in the wines with additional seeds. This led to the improvement in the wine' red hue and its resistance to SO2 bleaching. Furthermore, the wine added with seeds exhibited stronger astringency compared to those without. The findings provide a promising winemaking strategy to improve color stability and intensify the astringency of red wines through the utilization of grape seeds.

Fast and reliable quantification of aldosterone, cortisol and cortisone via LC-MS/MS to study 11ß-hydroxysteroid dehydrogenase activities in primary cell cultures.

Cell culture experiments can support characterization of enzymatic activities in healthy and tumorous human tissues. Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) enables simultaneous measurement of several steroids from a single sample, facilitating analysis of molecular pathways involved in steroid biosynthesis. We developed a reliable but fast method for quantification of cortisol, cortisone and aldosterone in cell culture supernatant. Validation, including investigation of matrix-matched calibration, was performed for two different cell types. Utility of the method was demonstrated in the study of 11ß-hydroxysteroid dehydrogenase type 2 (HSD11B2) activity under conditions of glucocorticoid and mineralocorticoid excess in different cell types. Aldosterone, cortisol and cortisone were extracted by liquid-liquid extraction (LLE) with methyl tert-butyl ether from 1 mL of cell culture supernatant. Steroids were separated on a Kinetex biphenyl column (50 ×2.1 mm, 2.6 µm) with gradient elution of water and methanol containing 2 mM ammonium format and analysed in multiple reaction monitoring mode after positive electrospray ionization. Application of the method included cell culture experiments with two different primary cell types, human coronary artery smooth muscle cells (HCSMC) and human coronary artery endothelial cells (EC). Cells were treated with different concentrations of cortisol, aldosterone and mifepristone, a glucocorticoid receptor antagonist and quantitative PCR was performed. The method exhibits high precision (CV ≤ 6 %) and accuracy (deviation from nominal concentration ≤ 6 %) for concentrations above the limit of quantification (LoQ) which is 0.11, 0.56 and 0.69 nmol/L for aldosterone, cortisone and cortisol, respectively. Calibration curves did not differ when prepared in media or solvent. The method enabled us to confirm activity of HSD11B2 and concentration dependent conversion of cortisol to cortisone in HCSMC (median conversion ratio at 140 nM cortisol = 1.46 %). In contrast we did not observe any HSD11B2 activity in EC. Neither addition of high aldosterone, nor addition of 1 µM mifepristone had impact on glucocorticoid concentrations. Quantitative PCR revealed expression of HSD11B1 and HSD11B2 in HCSMC but not in EC. We present a fast and reliable method for quantification of cortisol, cortisone and aldosterone in cell culture supernatants. The method enabled us to study HSD11B2 activity in two different cell types and will support future experiments investigating mechanisms of target organ damage in conditions of glucocorticoid and mineralocorticoid excess.
