Isoflavone-enriched soybean leaves (IESLs) were processed for drying, steaming, and fermentation, and bioactive compounds and biological activities were analyzed. During food processing, the content of fatty acids, water-soluble vitamins, total phenolics, total flavonoids, and isoflavone-aglycones increased from dried IESLs (DrIESLs) to fermented IESLs (FeIESLs). Especially, oleic acid (53.

Article Synopsis
  • This study analyzed the nutrients and antioxidant activities of different ratios (0%, 2.5%, 5%, and 10%) of mountain-cultivated ginseng (MCG) fermented with specific microorganisms.
  • It found that fermentation altered the content of isoflavones and ginsenosides, generally decreasing certain types while increasing others, particularly beneficial compounds like ginsenoside Rg3 and compound K.
  • The results suggest that higher ratios of MCG enhance the overall quality, antioxidant properties, and potential health benefits, making it valuable for food and pharmaceutical uses.

This study examines how functional disability worsens among older adults exposed to extreme heat, particularly those socially isolated. Analyzing data from over 35,000 older adults aged 50 or older from the Health and Retirement Study from 1996-2018, this study found that more frequent exposure to extreme heat is associated with an increase in the number of instrumental activities of daily living (IADL) that older adults find difficulty in performing over time. This heat-related disability progression is greater among those living alone and not working.

Article Synopsis
  • Incomplete resection rates vary among endoscopists, making it important to evaluate different removal techniques for small colorectal polyps.
  • This study compared the effectiveness and safety of cold snare endoscopic mucosal resection (CS-EMR) and hot snare endoscopic mucosal resection (HS-EMR) on polyps sized 6-9 mm.
  • Results showed that CS-EMR had a 0% rate of residual adenomas and similar efficacy in resection compared to HS-EMR, suggesting CS-EMR can be a standard method for removing small colorectal polyps.

  • This study investigates how extreme heat affects cognitive function in older adults, focusing on risk and protective factors using a social-ecological model.
  • Data from the Health and Retirement Study (1996-2016) was analyzed to see how extreme heat days impact fluid and crystallized intelligence scores in older adults aged 50 and up, considering factors like education and social interaction.
  • Results indicated that extreme heat negatively impacted fluid intelligence, with educational level, physical activity, and social engagement helping to mitigate these effects, suggesting the need for policies to enhance resilience in older adults during heat events.

Article Synopsis
  • - This study examined how solid-state fermentation with various fungi affects the nutritional components, isoflavones, and antioxidant activities of Apios americana Medikus (AAM), highlighting significant increases in fatty acid and amino acid content post-fermentation.
  • - The fermentation process, particularly with the fungus Monascus purpureus, resulted in a remarkable increase in total fatty acids (up to 26.3 times) and improved mineral contents, demonstrating notable nutritional enhancement.
  • - Isoflavone glycosides in unfermented AAM were converted to more beneficial aglycone forms during fermentation, leading to higher total phenolic and flavonoid contents, which suggests that fermented AAM could be a valuable ingredient for food and medicinal

Background And Aims: Colorectal endoscopic submucosal dissection (ESD) is challenging despite its usefulness. Underwater ESD (UESD) provides better traction and a clearer view of the submucosal layer than conventional ESD (CESD). This study compared the efficiency of UESD and CESD for large (20-50 mm) laterally spreading tumors (LSTs).

Article Synopsis
  • * The main source of this thermogenesis is the exothermic oxygen reduction reaction, which generates heat that can be transferred to other cellular organelles, including the nucleus.
  • * This heat activates the heat shock response in the nucleus, including the formation of stress granules and the relocation of heat shock factor 1 (HSF1), leading to increased gene expression that helps cells cope with thermal stress.

Introduction: A Monoplace hyperbaric chamber delivers oxygen to the patient's tissues through breathing. Gas monitoring inside the chamber is important because oxygen (O) is consumed, and carbon dioxide (CO) is increased because treatment is performed in a closed volume. This study aimed to advance the safety and efficacy of the monoplace hyperbaric chamber (MHC) through mechanical improvement in a gas monitoring system (GMS).

The current research was the first to prove the existence of fluctuations in the metabolite constituents and antioxidant properties in different organs (leaves, stems, and roots) of the mountain-cultivated ginseng (MCG) plant during a two-month maturation period. Four metabolites, including fatty acids, amino acids, ginsenosides, and phenolic phytochemicals, exhibited considerable differences in organs and maturation times with the following order: leaves > stems > roots. The predominant metabolite contents were found in leaves, with fatty acid (1057.

Background: Hodgkin lymphoma (HL) survivors who received chest radiotherapy are at risk for breast cancer and cardiovascular disease, but screening adherence is low. We assessed the acceptability/feasibility of a web-based educational intervention and its impact on knowledge of health risks and screening.

Methods: HL survivors were randomized to either an interactive online educational intervention or handouts only.

  • Ecological momentary assessment (EMA) is a method that helps capture the real-time experiences of family caregivers, particularly for those caring for adults with chronic conditions.
  • A systematic review identified 12 studies focused mainly on caregivers of individuals with Alzheimer's or dementia, revealing a 75% average compliance rate, which is below the ideal standard.
  • The review highlighted that while EMA is a feasible approach for collecting caregiver data, many studies lack essential information on caregivers' daily activities and emotional experiences, indicating a need for further research in this area.

Bridging the healthcare access gap and addressing COVID-19 vaccine hesitancy among rural-dwelling Black American adults residing in the Deep South require involvement of faith-based leaders in the community. This study explored perceived barriers and resources to meeting community needs, including vaccination, during the COVID-19 pandemic as reported by 17 Black American church leaders in the rural West Alabama Black Belt geographic region in May 2022. The main themes that emerged included (1) attending to community impact of COVID-19 illness and death; (2) maximizing health literacy and diminishing vaccine hesitancy through engaging in preventive health practices and sharing public health information; (3) addressing challenges created or exacerbated by COVID-19, including reduction in in-person attendance (particularly among adolescents and young adults), limited access to and literacy with technology, and political perceptions influencing engagement in preventive health behaviors; (4) maximizing technological solutions to increase attendance in the church; and (5) engaging in solution-focused and innovative initiatives to meet the identified needs in the congregation and community.

  • Researchers developed high isoflavone-enriched soy leaves (IESLs) using the chemical inducer ethephon at varying concentrations (0, 150, and 300 μg/mL) to enhance the nutritional properties of underutilized soy leaves.
  • The study found that, while proximate composition and fatty acids showed minimal differences, free amino acids and water-soluble vitamins increased significantly with higher ethephon concentrations, with isoflavone levels rising dramatically.
  • The findings suggest that soy leaves treated with ethephon could serve as valuable ingredients for functional foods, cosmetics, and natural medicinal products due to their increased nutritional components.

Despite the rapid rise in opioid prescription medication usage, little research has examined the role of early life adversity, such as childhood abuse, particularly in the context of race, in opioid prescription usage in adulthood. Guided by the life course perspective, the current study investigates whether experiencing childhood abuse increases the risk of opioid prescription use in adulthood and whether this association varies by race. Data were sourced from the second wave of the Midlife in the United States (MIDUS) study (2004-2005).
