Robust and highly reactive membranes for continuous disposal of chemical warfare agents: Effects of nanostructure and functionality in MOF and nanochitin aerogel composites.

Developing appropriate disposal of stockpiles of chemical warfare agents (CWAs) has gained significant attention as their lethal toxicity seriously harms humanity. In this study, a novel green-fabrication method with UiO-66 catalysts and amine-functionalized chitin nanofibers (ChNFs) was suggested to prepare durable and highly reactive membranes for decomposing chemical warfare agents (CWAs) in the continuous flow system. The strong interaction between ChNFs and the UiO-66 led to stable loading of the UiO-66 on the continuous nano-porous channel of the ChNF reactive membrane even with high loading of UiO-66 (70 wt% of UiO-66 in the ChNF substrate).

Intraoperative sudden arrhythmias in cervical spine surgery adjacent to the stellate ganglion: A case report.

Background: Atrial arrhythmias such as paroxysmal supraventricular tachycardia (PSVT) and atrial flutter (AF) are common in the perioperative setting. They commonly resolve spontaneously. However, occasionally, they may continually progress to fatal arrhythmias or cause complications.

Conventional or Alternative Mental Health Service Utilization According to English Proficiency Among Asians in the United States.

After the onset of the COVID-19 pandemic in 2020, Asian Americans in the United States have experienced a surge in anti-Asian crimes, leading to heightened psychological distress among this community. Consequently, the mental well-being of Asian Americans demands greater attention than ever. Regrettably, Asians tend to underutilize or delayed mental health care treatments.

Thin Film Composite Membranes as a New Category of Alkaline Water Electrolysis Membranes.

Alkaline water electrolysis (AWE) is considered a promising technology for green hydrogen (H ) production. Conventional diaphragm-type porous membranes have a high risk of explosion owing to their high gas crossover, while nonporous anion exchange membranes lack mechanical and thermochemical stability, limiting their practical application. Herein, a thin film composite (TFC) membrane is proposed as a new category of AWE membranes.

Chemical hazard of robotic hull in-water cleaning discharge on coastal embryonic fish.

In-water cleaning (IWC) involves the removal of biofilms and foulants from the hull of a ship using brush or water jet. During IWC, several factors associated with the harmful chemical contaminants release to the marine environment, which can create "hotspots" of chemical contamination in coastal areas. To elucidate the potential toxic effects of IWC discharge, we investigated developmental toxicity in embryonic flounder, which are sensitive life stage to chemical exposure.

General self-efficacy differentially moderates depressive symptoms in adults with epilepsy depending on seizure severity.

Purpose: We evaluated whether the relationship between general self-efficacy and depressive symptoms in patients with epilepsy differed depending on age, sex, and seizure status.

Methods: This multicenter, cross-sectional study was conducted on 299 adults with epilepsy, using the Beck Depression Inventory (BDI) and the General Self-efficacy Scale (GSES). We performed stepwise linear regression analysis and analysis of covariance with interaction terms.

Global Gender Inequality, Older Women, and the Call for Change in the United States.

Gender inequality that persists through much of their lives, from birth through adulthood, impacts women and their quality of life in their later years. With some variation this holds true in every nation in the global community. In older adults, the most apparent indication of gender inequality-and a linchpin-is the disproportionate impoverishment of older women compared to older men.

Association between sleep apnea severity and symptoms of depression and anxiety among individuals with obstructive sleep apnea.

Objective: We determined whether the severity of sleep apnea is associated with symptoms of depression and anxiety in patients with obstructive sleep apnea (OSA) and whether symptoms of OSA, other than respiratory events, are associated with depression and anxiety symptoms.

Methods: Depressive and anxiety symptoms were defined as a Patient Health Questionnaire-9 score of ≥10 and a Generalized Anxiety Disorder-7 score of ≥8, respectively. Sleep apnea severity and rapid eye movement-related OSA were evaluated using the apnea-hypopnea index (AHI).

Evaluating Indoor Air Phthalates and Volatile Organic Compounds in Nail Salons in the Greater New York City Area: A Pilot Study.

The Greater New York City area ranks highest in the United States in the number of nail salon technicians, primarily Asian immigrant women. Nail salon technicians are exposed to toxic phthalates and volatile organic compounds daily in nail salons. The purpose of this pilot study was to measure a mixture of phthalates and volatile organic compounds in nail salons in the Greater New York City area, and to characterize work-related determinants of indoor air quality in these nail salons.

Development and Modification of a Culturally Tailored Education Program to Prevent Breast Cancer in Korean Immigrant Women in New York City.

Breast cancer (BC) is the most common cancer in Korean American (KA) women. In view of its high prevalence in these women, their low screening rates, and the cultural influence of BC risk factors in their lifestyles, we developed a community-based culturally tailored BC prevention program, the Korean Breast Cancer Risk Reduction Program (KBCRRP). Guided by the PRECEDE-PROCEDE and health belief models, the KBCRRP was developed to achieve four goals: (1) healthy weight, (2) physically active lifestyle, (3) healthy diet, and (4) BC screening and adherence.

Dual burdens of felt stigma and depressive symptoms in patients with epilepsy: Their association with social anxiety, marriage, and employment.

Purpose: The present study evaluated whether patients with epilepsy with dual conditions of felt stigma and depressive symptoms are more strongly associated with social anxiety, being unmarried, and being unemployed than those with depressive symptoms or felt stigma alone.

Methods: This multicenter, cross-sectional study evaluated subjects using the Stigma Scale-Revised, the Patient Health Questionnaire-9, and the six-item versions of the Social Interaction Anxiety Scale, and the companion Social Phobia Scale. Subjects were grouped by depressive symptoms and felt stigma into four groups.

Pore-size control of chitin nanofibrous composite membrane using metal-organic frameworks.

Herein, environmentally benign chitin nanofiber (ChNF) membranes were fabricated by regulating suspension behavior. The introduction of zeolitic imidazole frameworks (ZIF-8) into the composite membranes led to the domain formation of ChNF derived by coordinative interaction, resulting in pore size-tunable membranes. Based on the rheological, morphological, and structural characterizations, the driving force of pore-size control was studied in the aqueous suspension of ChNF and ZIF-8 according to the relative concentration.

Robust Nanocellulose/Metal-Organic Framework Aerogel Composites: Superior Performance for Static and Continuous Disposal of Chemical Warfare Agent Simulants.

Environment-friendly and robust nanocellulose/metal-organic framework aerogel composites were prepared for effective detoxification of chemical warfare agent simulants both in static and dynamic continuous flow systems. For this, we fabricated a durable porous composite of the UiO-66 catalyst and TEMPO-oxidized cellulose nanofibers (TOCN) to examine as a detoxification filter. Even with over 50 wt % UiO-66, the obtained cellulose aerogel composites exhibited high stability without leaking of UiO-66 for 4 weeks under an aqueous state.

Decomposition of the Simulant 2-Chloroethyl Ethyl Sulfide Blister Agent under Ambient Conditions Using Metal-Organic Frameworks.

Metal organic frameworks (MOFs) have been suggested as promising materials for application in the degradation of chemical warfare agents, with the majority of studies to date focusing on nerve agents. One of the most prominent MOFs used in the detoxification of nerve agents is UiO-66, which is of interest as a future nerve agent decontaminant. However, blister agents, which constitute one of the most toxic and highly reactive categories of chemical agents, are yet to be examined as gas-phase decontamination targets using MOF structures.
