Health Effects of Drinking Water Produced from Deep Sea Water: A Randomized Double-Blind Controlled Trial

Global trends focus on a balanced intake of foods and beverages to maintain health. Drinking water (MIU; hardness = 88) produced from deep sea water (DSW) collected offshore of Muroto, Japan, is considered healthy. We previously reported that the DSW-based drinking water (RDSW; hardness = 1000) improved human gut health. The aim of this randomized double-blind controlled trial was to assess the effects of MIU on human health. Volunteers were assigned to MIU (n = 41) or mineral water (control) groups (n = 41). Participants consumed 1 L of either water type daily for 12 weeks. A self-administered questionnaire was administered, and stool and urine samples were collected throughout the intervention. We measured the fecal biomarkers of nine short-chain fatty acids (SCFAs) and secretory immunoglobulin A (sIgA), as well as urinary isoflavones. In the MIU group, concentrations of three major SCFAs and sIgA increased postintervention. MIU intake significantly affected one SCFA (butyric acid). The metabolic efficiency of daidzein-to-equol conversion was significantly higher in the MIU group than in the control group throughout the intervention. MIU intake reflected the intestinal environment through increased production of three major SCFAs and sIgA, and accelerated daidzein-to-equol metabolic conversion, suggesting the beneficial health effects of MIU.

COVID‐19 and dengue infection in Bangladesh: A case of coinfection where hemoptysis as first presentation

Bangladesh recently faced large outbreaks of both COVID‐19 and dengue. We present a case of COVID‐19 and dengue coinfection in a patient who presented with hemoptysis. Our results demonstrate that COVID‐19 and dengue fever are both public health issues in Bangladesh and other dengue‐endemic nations and that they can coexist.     

Chemical,Pharmacological and Computerized Molecular Analysis of Stem’s Extracts of Bauhinia scandens L. Provide Insights into the Management of Diarrheal and Microbial Infections

Bauhinia scandens L. (Family: Fabaceae) is commonly used to treat cholera, diarrhea, asthma, and diabetes disorder in integrative medicine. This study aimed to screen the presence of phytochemicals (preliminary and UPLC-QTOF–M.S. analysis) and to examine the pharmacological activities of Bauhinia scandens L. stems (MEBS) stem extracts. Besides, in silico study was also implemented to elucidate the binding affinity and drug capability of the selected phytochemicals. In vivo anti diarrheal activity was investigated in mice models. In vitro, antibacterial and antifungal properties of MEBS against several pathogenic strains were evaluated using the disc diffusion method. In addition, in silico study has been employed using Discovery studio 2020, UCFS Chimera, PyRx autodock vina, and online tools. In the anti-diarrheal investigation, MEBS showed a significant dose-dependent inhibition rate in all three methods. The antibacterial and antifungal screening showed a remarkable zone of inhibition, of the diameter 14–26 mm and 12–28 mm, by MEBS. The present study revealed that MEBS has remarkable anti-diarrheal potential and is highly effective in wide-spectrum bacterial and fungal strains. Moreover, the in silico study validated the results of biological screenings. To conclude, MEBS is presumed to be a good source in treating diarrhea, bacterial and fungal infections.     

Combined experimental and computational study of Al2O3 catalyzed transamidation of secondary amides with amines

Amides are the most extensively used substances in both synthetic organic and bioorganic chemistry. Unfortunately, the traditional synthesis of amides suffers from some important drawbacks, including low atom efficiency, high catalyst loading, separation of products from the reaction mixture and production of byproducts. Al₂O₃ is an amphoteric catalyst that activates the carbonyl carbon of the secondary amide group and helps the C–N cleavage of the reactant amide group by attacking the N–H hydrogen. By using the concepts of amphoteric properties of Al₂O₃, amides were synthesized from secondary amides and amines in the presence of triethylamine solvent. Several aliphatic and aromatic amines were used for the transamidation of N-methylbenzamide in the presence of the Al₂O₃ catalyst. Moreover, using the Gaussian09 software at the DFT level, HUMO, LUMO and the intrinsic reaction coordinates (IRCs) have also been calculated to find out the transition state of the reaction and energy. In this study, five successful compounds were synthesized by the transamidation of secondary amides with amines using a reusable Al₂O₃ catalyst. The catalyst was reused several times with no significant loss in its catalytic activity. The products were purified by recrystallization and column chromatography techniques. This catalytic method is effective for the simultaneous activation of the carbonyl group and N–H bond by using the Al₂O₃ catalyst.

Functional fitness gain varies in older adults depending on exercise mode

Various exercise modes are available to improve functional fitness (FF) in older adults. However, information on the comparative capability of different exercise modes to improve FF is insufficient. PURPOSE: To compare the effects of aerobic, resistance, flexibility, balance, and Tai Chi programs on FF in Japanese older adults. METHODS: FF was evaluated using a chair stand, arm curl, up and go, sit and reach, back scratch, functional reach, and 12-min walk. One hundred thirteen older adults (73 +/- 6 yr, 64 men, 49 women) volunteered for one of five exercise groups: aerobic (AER), resistance (RES), balance (BAL), flexibility (FLEX), and Tai Chi (T-CHI), or they were assigned to the wait-list control group (CON). Programs were performed for 12 wk, 2 d x wk(-1) (RES, BAL, FLEX, T-CHI) or 3 d x wk(-1) (AER), and 90 min x d(-1). RESULTS: Improvement in cardiorespiratory fitness was limited to AER (16%). Improvements in upper- and lower-body strength and balance/agility were outcomes of RES, BAL, and T-CHI. RES elicited the greatest upper-body strength improvement (31%), whereas BAL produced the greatest improvement in lower-body strength (40%). Improvements in balance/agility were similar across RES (10%), BAL (10%), and T-CHI (10%). Functional reach improved similarly in AER (13%), BAL (16%), and RES (15%). There were no improvements in flexibility. CONCLUSION: Results suggest that a single mode with crossover effects could address multiple components of fitness. Therefore, a well-rounded exercise program may only need to consist of two types of exercise to improve the components of functional fitness. One type should be aerobic exercise, and the second type could be chosen from RES, BAL, and T-CHI.
