These findings suggest that PA has the similar effect with metformin, which can improve the endocrine environment and oocyte quality of PCOS mice.

The U.S. Army requires community health coalitions to develop targeted action plans in order to more effectively address top public health priorities. Reviews of community action plans indicate that they are often poorly developed and not fully implemented. To date, the U.S. Army has not implemented a standardized tool or process to evaluate action plans and provide recommendations for improvement to local installations. The Plan Quality Index (PQI) is an evidence-based, standardized tool that has been used successfully by technical experts to review and improve community action plans related to the prevention of obesity, injury and violence, and cancer.

The objective of this project was to determine the usability of the PQI and to provide recommendations for improving community health action plans focused on injury prevention for the U.S. Army. Five Health Promotion Project Officers and one Health Promotion Project Assistant at Army Public Health Center were trained on the PQI and reviewed injury preventjury prevention in the U.S. Army. As a result, the PQI may be beneficial as a standard tool for community health improvement planning and consultation throughout the Army Public Health Center.

The coronavirus pandemic (COVID-19) has spread worldwide via international travel. This study traced its diffusion from the global to national level and identified a few superspreaders that played a central role in the transmission of this disease in India.

We used the travel history of infected patients from 30 January to 6 April 6 2020 as the primary data source. A total of 1386 cases were assessed, of which 373 were international and 1013 were national contacts. The networks were generated in Gephi software (version 0.9.2).

The maximum numbers of connections were established from Dubai (degree 144) and the UK (degree 64). Dubai's eigenvector centrality was the highest that made it the most influential node. The statistical metrics calculated from the data revealed that Dubai and the UK played a crucial role in spreading the disease in Indian states and were the primary sources of COVID-19 importations into India. Based on the modularity class, different clusters were shown to form across Indian states were located, and a significant spread was identified in states like Gujarat, Rajasthan, Maharashtra, Kerala and Karnataka. The COVID-19's spread in phase one was traced using the travelling history of the patients, and it was found that most of the transmissions were local.

Alcohol and substance misuse is prevalent among older adults, yet underdiagnosed and undertreated. More substance misuse intervention programs specifically designed for older adults and offered in various settings are needed. This project's objectives were to [1] provide a detailed description of a Geriatric Substance Abuse Recovery Program (GSARP) designed and implemented at post-acute rehabilitation units of a Skilled Nursing Facility; and [2] report findings of a study conducted to evaluate if GSARP participation among post-acute care patients with substance misuse issues can optimize rehabilitation outcomes (i.e., being discharged home vs. another setting).

A pre-post test study design with data obtained from patients' electronic medical record upon facility admission, during post-acute stay, and after discharge (N=271). Based on Andersen's model of health care utilization, we investigated which predisposing factors (e.g., ethnicity), enabling factors (e.g., cognition, social support), and need-related factors (e.g., ADL functioning), as well as health behaviors (e.g., GSARP participation) predicted likelihood of being discharged home versus another discharge setting.

Patients participating in the GSARP and patients who received social support from family members and friends during their post-acute stay were more likely to be discharged home. Patients with severe cognitive impairment were less likely to be discharged home.

The GSARP eliminates some common barriers often encountered in the screening and delivery process of substance misuse interventions for older adults. Findings support the effectiveness of the GSARP in optimizing rehabilitation outcomes for older adults with substance misuse issues.

The Stryker Surgical Simulator is a hybrid, temporal bone simulator that uses both tactile and haptic feedback combined with a computer interface. We sought to validate this simulator as an otolaryngology resident training tool for performing tympanomastoidectomy.

15 residents and staff performed five basic cortical mastoidectomies. Staff surgeons comprised the "expert" cohort and resident surgeons comprised the "trainee" cohort. Subjective evaluation of the face validity and content validity was assessed via pre- and postquestionnaires. Objective evaluation of content validity was assessed through grading of each temporal bone dissection specimen, comparing time to task completion, and calculating the rate of injury to critical structures. Study approved by the Institutional Review Board (2013.0001).

Post hoc questionnaires showed that both staff and residents subjectively rated the simulator favorably on face validity, content validity, and all global assessment categories, though there were no signif.

Despite favorable subjective evaluations by both staff and residents, objective discrimination between experienced and novice participants was not achieved. This was likely in part due to inherent design flaws of the simulator. This emphasizes the potential shortcomings of surgical simulation models for highly technical procedures and points to the importance of intensive study and validation prior to incorporation of commercial training models into surgical training programs.

To demonstrate that early adolescent binge drinking (BD) increases the risk for and/or severity of psychopathology in post-9/11 Veterans and determine if mild traumatic brain injury (mTBI) modifies risk.

Post-9/11 Veterans (n = 375) were classified into two groups 57 Veterans with a history of early adolescent BD (E-BD; age of onset <15) and 318 who did not BD until age 15 or older (late-BD or L-BD; age of onset ≥15). History of military mTBI and mental health disorders were also assessed following military service.

Logistic regression and analysis of variance (ANOVA) analyses revealed that the E-BD's had significantly higher prevalence of alcohol use disorders (AUDs) and more severe symptoms of AUD, substance use disorder (SUD), depression and stress. Two-way ANOVAs showed that history of military mTBI was differentially associated with posttraumatic stress disorder (PTSD) incidence and severity among Veterans who had engaged in early adolescent BD. Specifically, Veterans with a history of both early adolescent BD and military mTBI were at greater risk for a PTSD diagnosis and had more severe symptoms of PTSD than those with only a history of adolescent BD. Bay 11-7085 cell line The greater PTSD symptom severity in the comorbid group was driven by hyperarousal symptoms.

A history of BD during early adolescence is prevalent among Veterans and is related to higher risk for AUD and more severe AUD, SUD, mood and stress symptoms later in life. Veterans with early BD and military mTBI showed greater incidence and severity of PTSD, indicating that mTBI, a common comorbidity among post-9/11 Veterans, exacerbates risk.

Tanshinone IIA (Tan IIA), a pharmacologically active component isolated from the rhizome of the Chinese herb Salvia miltiorrhiza Bunge (Danshen), has been reported to possess an anti-cancer effect in gastric cancer. However, its mechanisms are still not fully understood. In the present study, we found that Tan IIA induced ferroptosis in BGC-823 and NCI-H87 gastric cancer cells. Tan IIA increased lipid peroxidation and up-regulated Ptgs2 and Chac1 expression, two markers of ferroptosis. Ferrostatin-1 (Fer-1), an inhibitor of lipid peroxidation, inhibited Tan IIA caused-lipid peroxidation and Ptgs2 and Chac1 expression. In addition, Tan IIA also up-regulated p53 expression and down-regulated xCT expression. Tan IIA caused decreased intracellular glutathione (GSH) level and cysteine level and increased intracellular reactive oxygen species (ROS) level. p53 knockdown attenuated Tan IIA-induced lipid peroxidation and ferroptosis. Tan IIA also induced lipid peroxidation and ferroptosis in BGC-823 xenograft model, and the anti-cancer effect of Tan IIA was attenuated by Fer-1 in vivo. Therefore, Tan IIA could suppress the proliferation of gastric cancer via inducing p53 upregulation-mediated ferroptosis. Our study have identified a novel mechanism of Tan IIA against gastric cancer, and might provide a critical insight into the application of Tan IIA in gastric cancer intervention.Nitrogen (N) deficiency adversely affects tree growth. Additionally, γ-aminobutyric acid (GABA) is closely associated with growth and stress responses because of its effects on carbon (C) and N metabolism. However, little is known about its roles related to plant adaptations to N-deficient conditions. In this study, we analyzed the effects of GABA (0, 2 and 10 mM) applications on the growth traits and physiological responses of poplar (Populus alba × P. glandulosa '84K') seedlings under high N (HN) and low N (LN) conditions. We found that the added GABA interacted with N to affect more than half of the studied parameters, with greater effects in LN plants than in HN plants. Under LN conditions, the GABA application tended to increase poplar growth, accompanied by increased xylem fiber cell length and xylem width. In stems, exogenous GABA increased the abundance of non-structural carbohydrates (starch and sugars) and tricarboxylic acid cycle intermediates (succinate, malate and citrate), but had the opposite effect on the structural C contents (hemicellulose and lignin). Meanwhile, exogenous GABA increased the total soluble protein contents in leaves and stems, accompanied by significant increases in nitrate reductase, nitrite reductase and glutamine synthetase activities in leaves, but significant decreases in those (except for the increased glutamate synthetase activity) in stems. A multiple factorial analysis indicated that the nitrate assimilation pathway substantially influences poplar survival and growth in the presence of GABA under LN conditions. Interestingly, GABA applications also considerably attenuated the LN-induced increase in the activities of leaf antioxidant enzymes, including peroxidase and catalase, implying that GABA may regulate the relative allocation of C and N for growth activities by decreasing the energy cost associated with stress defense. Our results suggest that GABA enhances poplar growth and adaptation by regulating the C and N metabolic flux under N-deficient conditions.
