Extract mixture of plants (OXYLIA) inhibits fat accumulation by blocking FAS-related factors and promoting lipolysis via cAMP-dependent PKA activation.

Background: Obesity is characterized by an imbalance between energy intake and expenditure, leading to the excessive accumulation of triglycerides in adipose tissue. Objective: This study investigated the potential of Oxylia to prevent obesity in mice fed with a high-fat diet (HFD). Design: C57BL/6J mice were fed with one of the following five diets - AIN93G normal diet (normal control), 60% (HFD; control), HFD containing metformin at 40 mg/kg body weight (b.w.) (Met; positive control), HFD containing Oxylia at 30 mg/kg b.w. (O30), or HFD containing Oxylia at 60 mg/kg b.w. (O60) - for 15 weeks. Results: Mice under an HFD supplemented with Oxylia had decreased body weight gain, adipose tissue weight, and adipose tissue mass. In addition, triglyceride (TG), total cholesterol, and VLDL/LDL cholesterol levels were lower in the O60 groups than in the HFD-fed control group. Moreover, Oxylia supplementation decreased the expression of adipogenesis-related mRNAs and lipogenesis-related proteins while increasing the expression of lipolysis-related proteins in white adipose tissue and thermogenesis-related proteins in brown adipose tissue. Conclusions: These findings suggest that Oxylia has potential as a functional food ingredient for the prevention and treatment of obesity and related metabolic disorders.

Analyses of the Chemical Composition of Plasma-Activated Water and Its Potential Applications for Vaginal Health.

This study aimed to elucidate the unique chemical compositions of plasma-activated water (PAW) and the potential antibacterial efficacy of PAW as a novel vaginal cleanser. We analyzed the ion compositions (four anions: F-, Cl-, NO3-, SO42-; five cations: Na+, NH4+, K+, Mg2+, Ca2+) of several formulations of PAW generated at different electrical powers (12 and 24 V) at various treatment time points (1, 10, and 20 min), and stay durations (immediate, 30, and 60 min). As treatment duration increased, hypochlorous acid (HOCl), Ca2+, and Mg2+ concentrations increased and Cl- concentration decreased. Higher electrical power and longer treatment duration resulted in increased HOCl levels, which acts to prevent the growth of general microorganisms. Notably, PAW had no antibacterial effects against the probiotic, Lactobacillus reuteri, which produces lactic acid and is important for vaginal health. These findings indicate that PAW contains HOCl and some cations (Ca2+ and Mg2+), which should help protect against pathogens of the vaginal mucosa and have a cleansing effect within the vaginal environment while not harming beneficial bacteria.

Exploring the experience of health professionals who cared for patients with coronavirus infection: Hospitalised isolation and self-image.

AIMS AND OBJECTIVES: This study aimed to examine the lived experience of physicians and nurses who underwent hospitalised isolation during the Middle East respiratory syndrome coronavirus outbreak that hit Korea in 2015, and how it may have affected their professional self-image. BACKGROUND: Health professionals caring for patients during infectious outbreaks such as the Middle East respiratory syndrome have reported negative psychological effects. However, little is known about how the experience influences their professional self-image. DESIGN: An interpretive phenomenological approach was applied using individual in-depth interviews. METHODS: Through purposeful and snowball sampling, 11 health professionals who had experienced hospital isolation due to suspicious symptoms of Middle East respiratory syndrome during the outbreak, participated in face-to-face interviews (50-90 min). We adhered to the Consolidated Criteria for Reporting Qualitative Research guideline for reporting. RESULTS: Six themes were identified: (a) engulfed in chaos and exhaustion; (b) feeling hurt and constrained by the rejection and blame; (c) anxiety induced by the enclosed environment; (d) dread of this uncertain and critical disease; (e) sustained by family and colleagues; and (f) reflection at this turning point, expanding self-understanding and seeking a balance. CONCLUSION: Hospitalised isolation was a "turning point" that appeared to change health professionals' sense of identity and direction. RELEVANCE TO CLINICAL PRACTICE: Preparedness for infectious epidemics should ensure tangible assistance, protection, and clear communication with health professionals, with careful attention to their psychological needs and affirmation of their self-image in the aftermath.

Effect of herbal extracts and supplement mixture on alcohol metabolism in Sprague Dawley-rats.

This study aimed to investigate the effect of mixture of herbal extracts and supplementary formula (FNP-C) on hangovers and antioxidant enzymes in alcohol-induced liver damage in rats. HepG2 cells were used as the experimental cells and divided into five groups: non-treated control (normal), alcohol-induced control (control), mixture of herbal extracts (FNP-B), FNP-C, and a commercial treatment of liver diseases (Livers®); inhibition of detoxification and alcohol-induced damage was confirmed in vivo. Blood alcohol and acetaldehyde concentration after alcohol consumption were measured in a timely manner; alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), superoxide dismutase (SOD), glutathione (GSH), glutathione transferase (GST), and lactate dehydrogenase (LDH) levels were measured in the liver. FNP-C exhibited the highest effect. When FNP-C was administered to alcohol-induced animals, blood alcohol and acetaldehyde concentration decreased compared to FNP-B and Livers®. FNP-C reduced ADH levels and improved LDH, GSH, GST, and SOD levels. The FNP-C group was effective in preventing alcohol-induced hangovers and liver damage. Thus, FNP-C improves hangovers and increases antioxidant activity in an alcohol-induced model. Adding amino acids and vitamins to natural ingredients can potentially enhance the effect of improving hangovers.

Senescence-inducible LEC2 enhances triacylglycerol accumulation in leaves without negatively affecting plant growth.

The synthesis of fatty acids and glycerolipids in wild-type Arabidopsis leaves does not typically lead to strong triacylglycerol (TAG) accumulation. LEAFY COTYLEDON2 (LEC2) is a master regulator of seed maturation and oil accumulation in seeds. Constitutive ectopic LEC2 expression causes somatic embryogenesis and defects in seedling growth. Here, we report that senescence-inducible LEC2 expression caused a threefold increase in TAG levels in transgenic leaves compared with that in the leaves of wild-type plants. Plant growth was not severely affected by the accumulation the TAG in response to LEC2 expression. The levels of plastid-synthesized lipids, mono- and di-galactosyldiacylglycerol and phosphatidylglycerol were reduced more in senescence-induced LEC2 than in endoplasmic reticulum-synthesized lipids, including phosphatidylcholine, phosphatidylethanolamine and phosphatidylinositol. Senescence-induced LEC2 up-regulated the expression of many genes involved in fatty acid and TAG biosynthesis at precise times in senescent leaves, including WRINKLED1 (WRI1), which encodes a fatty acid transcription factor. The expressions of glycerol-3-phosphate dehydrogenase 1 and phospholipid:diacylglycerol 2 were increased in the transgenic leaves. Five seed-type oleosin-encoding genes, expressed during oil-body formation, and the seed-specific FAE1 gene, which encodes the enzyme responsible for the synthesis of C20:1 and C22:1 fatty acids, were also expressed at higher levels in senescing transgenic leaves than in wild-type leaves. Senescence-inducible LEC2 triggers the key metabolic steps that increase TAG accumulation in vegetative tissues.

Maternal Psychosocial Factors that Affect Breastfeeding Adaptation and Immune Substances in Human Milk.

PURPOSE: This study was to identify relationships of maternal psychosocial factors including mother's mood state, childcare stress, social support and sleep satisfaction with breastfeeding adaptation and immune substances in breast milk, especially secretory immunoglobulin A (sIgA) and transforming growth factor-beta 2 (TGF-beta2). METHODS: Data were collected from 84 mothers who delivered full-term infants by natural childbirth. Structured questionnaires and breast milk were collected at 2~4 days and 6 weeks postpartum. Data were analyzed using descriptive statistics, Pearson's correlation, multiple linear regression, and generalized estimating equation (GEE). RESULTS: Scores for the breastfeeding adaptation scale were significantly related with child care stress, mood state and social support. Mother's anger was positively correlated with the level of sIgA in colostrum (p<.01). Immune substances of breastmilk was significantly influenced by time for milk collection (p<.001) and the type of breastfeeding (sIgA, p<.001, TGF-beta2, p=.003). Regression analysis showed that breastfeeding adaptation could be explained 59.1% by the type of breastfeeding, childcare stress, the Profile of Mood States, emotional support and sleep quality (F=16.67, p<.001). CONCLUSION: The findings from this study provide important concepts of breastfeeding adaptation program and explanation of psychosocial factors by immune substances in breast milk. Future research, specially, bio-maker research on breast milk should focus on the ways to improve breastfeeding adaptation.
