Perovskite nanocomposites: synthesis, properties, and applications from renewable energy to optoelectronics.

The oxide and halide perovskite materials with a ABX structure exhibit a number of excellent properties, including a high dielectric constant, electrochemical properties, a wide band gap, and a large absorption coefficient. These properties have led to a range of applications, including renewable energy and optoelectronics, where high-performance catalysts are needed. However, it is difficult for a single structure of perovskite alone to simultaneously fulfill the diverse needs of multiple applications, such as high performance and good stability at the same time.

This study was performed to evaluate the effects of rye silage treated with sodium formate (Na-Fa) and lactic acid bacteria (LAB) inoculants on the ruminal fermentation characteristics, methane yield and energy balance in Hanwoo steers. Forage rye was harvested in May 2019 and ensiled without additives (control) or with either a LAB inoculant or Na-Fa. The LAB () were inoculated at 1.

Quality Characteristics of Meat Analogs through the Incorporation of Textured Vegetable Protein and Larvae in the Presence of Transglutaminase.

Alternative protein sources with greater nutritional value and a lower environmental footprint have recently attracted interest in the production of meat substitutes. However, it is required that these alternatives mimic the texture and structure of meat. This study investigated varying ratios of textured vegetable proteins (TVP) to larvae (brown mealworm; TM) with the addition of transglutaminase (TG) to determine the quality characteristics of these emulsions.

Sustainable management of medical plastic waste through carbon dioxide-assisted pyrolysis.

To address the challenges associated with medical plastic waste and to characterize its heterogeneity, non-recyclability, and potential biohazard risks, this study explored a carbon dioxide (CO)-assisted pyrolysis process as a sustainable disposal method. Medical plastic waste typically includes polypropylene, polystyrene, and polyvinyl chloride. To experimentally evaluate the functional reactivity of CO, we employed three pyrolysis setups (one-stage, two-stage, and catalytic processes).

Measurements of the Branching Fraction, Polarization, and CP Asymmetry for the Decay B^{0}→ωω.

We present a comprehensive study of B^{0}→ωω decays using 772×10^{6}  BB[over ¯] pairs collected with the Belle detector at the KEKB e^{+}e^{-} collider. This process is a suppressed charmless decay into two vector mesons and can exhibit interesting polarization and CP violation. The decay is observed for the first time with a significance of 7.

Optimized method development and validation for determining donepezil in rat plasma: A liquid-liquid extraction, LC-MS/MS, and design of experiments approach.

Donepezil (DPZ), a piperidine-based reversible cholinesterase inhibitor, finds extensive use in treating Alzheimer's disease (AD). Originally designed as an oral formulation, DPZ encounters drawbacks such as a brief duration of action and reduced treatment effectiveness in elderly patients with memory impairment or difficulty swallowing medications. To address these issues and improve patient compliance, researchers are actively exploring alternative DPZ formulations.

Intraocular Concentration of Stem Cell Factor/c-KIT and Galectin-1 in Retinal Diseases.

Purpose: To investigate the intraocular concentration profiles of stem cell factor (SCF)/c-KIT, galectin-1 (GAL-1), and vascular endothelial growth factor (VEGF)-A with regard to retinal disease and treatment response.

Nursing care services to address unmet supportive care needs among cancer survivors: a systematic review.

Background: The increasing population of cancer survivors poses a significant challenge for healthcare systems globally, necessitating comprehensive post-treatment care to address diverse physical, psychological, and social needs.

Objective: This systematic review aims to synthesize and critically evaluate the current evidence concerning the unmet needs for nursing services among cancer survivors, spanning various dimensions of survivorship care.

Methods: A systematic search was conducted across major databases, including PubMed, CINAHL, and PsycINFO, to identify relevant studies investigating the unmet needs and health-related quality-of-life (HRQOL) of nursing services led by nurses among cancer survivors.

Mussel-inspired sulfated hyaluronan cryogel patch with antioxidant, anti-inflammatory, and drug-loading properties for multifunctional wound adhesives.

Wounds, characterized by the disruption of the continuity of body tissues resulting from external trauma, manifest in diverse types and locations. Although numerous wound dressings are available for various wound scenarios, it remains challenging to find an integrative wound dressing capable of addressing diverse wound situations. We focused on utilizing sulfated hyaluronan (sHA), known for its anti-inflammatory properties and capacity to load cationic drugs.

Association between diabetic status and risk of acute pancreatitis: A nationwide population-based study.

Objective: There have been several epidemiologic studies on the association between diabetes mellitus and acute pancreatitis. However, there is no solid evidence, and the effect of diabetes mellitus severity on acute pancreatitis incidence is not well known. This study aimed to evaluate the association between diabetic status and the risk of acute pancreatitis in a nationwide population-based cohort.

Risk of visual impairment according to the comorbidity of systemic and ocular diseases.

Purpose: To investigate the risk of visual impairment (VI) based on the presence or absence of four diseases: hypertension (HTN), diabetes mellitus (DM), glaucoma, and diabetic retinopathy (DR).

Methods: This retrospective population-based study included 1,000,000 randomly selected participants from the National Health Checkup Program database between 2015 and 2016. VI was defined as a presenting visual acuity ≤ 0.

The Effects of Ketogenic Diets and Ketone Supplements on the Aerobic Performance of Endurance Runners: A Systematic Review.

Context: Ketogenic diets and ketone supplements have gained popularity among endurance runners given their purported effects: potentially delaying the onset of fatigue by enabling the increased utilization of the body's fat reserve or external ketone bodies during prolonged running.

Objective: This systematic review was conducted to evaluate the effects of ketogenic diets (>60% fat and <10% carbohydrates/<50 g carbohydrates per day) or ketone supplements (ketone esters or ketone salts, medium-chain triglycerides or 1,3-butadiol) on the aerobic performance of endurance runners.

Data Sources: A systematic search was conducted in PubMed, Web of Science, Pro Quest, and Science Direct for publications up to October 2023.

Still in there-citizens' well-being and PTSD after Seoul Halloween crowd crush in Korea: a cross-sectional study.

The October 29, 2022, Seoul Halloween Crowd Crush (SHCC) caused the loss of 159 lives, making it the deadliest global mass-gathering disaster between 2018 and 2022. Despite the fact that years have passed since the incident, there remains a significant gap in research addressing the mental health of citizens to evaluate their recovery progress. Therefore, in this study, a survey was conducted to assess citizens' anxiety, depression, post-traumatic stress disorder (PTSD), and well-being after the SHCC.

Dexamethasone nanocrystals-embedded hydroxypropyl methylcellulose hydrogel increases cochlear delivery and attenuates hearing loss following intratympanic injection.

Herein, dexamethasone (DEX) nanocrystalline suspension (NS)-embedded hydrogel (NS-G) was constructed using a hydroxypropyl methylcellulose (HPMC) polymer to enhance cochlear delivery and attenuate hearing loss following intratympanic (IT) injection. Hydrophobic steroidal nanocrystals were prepared using a bead milling technique and incorporated into a polysaccharide hydrogel. The NS-G system with HPMC (average molecular weight, 86,000 g/mol; 15 mg/mL) was characterized as follows: rod-shaped drug crystalline; particle size <300 nm; and constant complex viscosity ≤1.
