Studies have demonstrated that both mortality and severe illness rates exist significant difference in different gender COVID-19 patients, but the reasons are still very mysterious to date. Here, we firstly find that the survival outcome of female patients is better to male patients through analyzing the 3044 COVID-19 cases. Secondly, we identify many important master regulators [e.g. STAT1/STAT2 and zinc finger (ZNF) proteins], in particular female patients can express more ZNF proteins and stronger transcriptional activities than male patients in response to SARS-CoV-2 infection. Thirdly, we discover that ZNF protein activity is significantly negative correlation with the SARS-CoV-2 load of COVID-19 patients, and ZNF proteins as transcription factors can also activate their target genes to participate in anti-SARS-CoV-2 infection. Fourthly, we demonstrate that ZNF protein activity is positive correlation with the abundance of multiple immune cells of COVID-19 patients, implying that the highly ZNF protein activity might promote the abundance and the antiviral activity of multiple immune cells to effectively suppress SARS-CoV-2 infection. Taken together, our study proposes an underlying anti-SARS-COV-2 role of ZNF proteins, and differences in the amount and activity of ZNF proteins might be responsible for the distinct prognosis of different gender COVID-19 patients.
Incisional hernia is a frequent postoperative complication after midline laparotomy. Prophylactic mesh augmentation in abdominal wall closure after elective surgery is recommended, but its role in emergency surgery is less well defined.
This prospective randomized trial evaluated the incidence of incisional hernia in patients undergoing urgent midline laparotomy for clean-contaminated surgery. Closure using a slowly absorbable running suture was compared with closure using an additional sublay mesh (Parietex ProGrip™). Patients were randomized just before abdominal wall closure using computer-generated permuted blocks. Patients, care providers, staff collecting data, and those assessing the endpoints were all blinded to the group allocation. Patients were followed up for 24 months by means of clinical and ultrasonographic evaluations.
From January 2015 to June 2018, 200 patients were randomized 100 to primary closure (control group) and 100 to Parietex ProGrip™ mesh-supported closure (mesh group). Eightntaminated wounds was safe and effective in reducing the incidence of incisional hernia, although larger studies with longer follow-up are required.
To evaluate the ability of pathology modules to promote learning of pathology-related course content in a preclinical medical education curriculum.
Pathology modules were created for the "Hematology/Oncology" and "Women's Health" (WH) courses. Students were recruited over 2 consecutive academic years; cohorts 1 and 2 refer to 2 separate groups of students in years 1 and 2, respectively, of the study. Course performance data were collected.
Use of pathology modules resulted in a statistically significant higher correlation between performance on the final examination and pathology-related questions in the Hematology/Oncology course and written examination and pathology-related questions in cohort 1 in the WH course. There was statistically significant improvement (P = .026) on pathology-related laboratory practical examination questions in the WH course for cohort 1, and no other statistically significant improvement for the other cohorts and examinations. The percentage of students completing all or part of the modules was highest in the WH course for cohort 1 (60%) compared with WH course cohort 2 (33%) and Hematology/Oncology cohort 1 (30%) and cohort 2 (39%).
Pathology modules may improve acquisition and retention of pathology-related course content when used appropriately.

When leaf age is taken into account, it is generally considered discontinuous, and leaves are classified into age categories based on qualitative observations. Here, we quantified age-dependent changes in leaf functional traits such as the maximum carboxylation rate of Rubisco (Vcmax), stomatal control (Cgs%), leaf dry mass per area (LMA) and leaf macronutrient concentrations for nine naturally growing Amazon tropical trees with variable phenological strategies. Leaf ages were assessed by monthly censuses of branch-level leaf demography; we also performed leaf trait measurements accounting for leaf chronological age based on days elapsed since the first inclusion in the leaf demography, not predetermined age classes. learn more At the tree community scale, a nonlinear relationship between Vcmax and leaf age existed young, developing leaves showed the locould not be confirmed for all trees.Deoxynivalenol (DON) is one of the most prevalent Fusarium mycotoxins which cause detrimental effects on human and animal reproductive systems by inducing oxidative stress. Increasing evidence has suggested the potential roles of melatonin in protecting granulosa cells from oxidative injury, but the underlying mechanisms remain largely elusive. Here, we demonstrated that suppression of FOXO1 and endoplasmic reticulum (ER) stress was engaged in melatonin-mediated protection against oxidative damage in human granulosa cells upon DON exposure in vitro. DON induced excess reactive oxygen species (ROS) accumulation, cells viability loss, reduced estradiol-17β and progesterone production in human granulosa cells, whereas melatonin ameliorated these phenotypes. Next, we found that the protective effect of melatonin against apoptosis was via reducing ER stress because inhibition of ER stress displayed similar protective effects during DON treatment. Moreover, melatonin provided no additional protection when ER stress was inhibited. We further found that FOXO1 is a pivotal downstream effector of melatonin and ER stress in regulating DON-induced apoptosis in human granulosa cells. Blocking of FOXO1 reduced DON-induced cells death and FOXO1 activation could be suppressed by melatonin or ER stress inhibitor. However, melatonin failed to further restore cells viability in the presence of FOXO1 inhibitor. Collectively, our results reveal a new mechanism of melatonin in protecting against DON-induced apoptosis and dysfunction by suppressing ER stress and FOXO1 in human granulosa cells.
