Antimicrobial resistance is one of the most significant threats to our present and future. Recently, it has been suggested that antibiotic-resistant microorganisms also exhibit resistance to heavy metals and disinfectants, and these resistance profiles may interact with each other. Microorganisms can be exposed to heavy metals and disinfectants in different ways in various environments. They are especially likely to be exposed to quaternary ammonium compounds used in the food industry or heavy metals due to tap wat [...]

The present article describes some characteristics of the effect of essential oil (EO) extracted from Ziziphora clinopodioides harvested from Armenian highlands on microglial cell lines (BV-2 wild-type (WT) and acyl-CoA oxidase1 (ACOX1)-deficient (Acox1–/–) cells). The mutant cell line was used as a model to investigate cellular oxidative damage following EO treatment. The main components of the tested EO were pulegone, isomenthone, 1,8-cineole, piperitone, and neomenthole, with concentrations of 42.1%, [...]

To increase power level in an autonomous microgrid, higher voltage is necessary. In this paper, detailed Matlab/Simulink modeling of a microgrid operated at medium-voltage level and at constant frequency has been conducted. Modified boost converter and medium-frequency transformer isolated DC/DC converter are adopted for both solar energy and wind energy harnessing in order for them to be connected with the microgrid. This paper further adopted a differential evolution (DE)-based method to carry out load flow analy [...]

As the medical world continues to search for ways of improving the swallowing of many millions of Dysphagia sufferers around the world, this paper is devoted to presenting the case for carbonated water to be considered as a potential solution for many. The effectiveness of carbonated water (CW) in the rehabilitation of Dysphagia has been studied periodically over the last thirty years and some significant positive results have been recorded – but it is now proposed that further research should be directed to examin [...]

The water balance is severely disturbed in post-mining landscapes like Lusatia/Germany. Mine waters (amd) enter the environment and spread in groundwater and surface waters. Groundwater containing high amounts of pyrite weathering products flows into receiving waters due to lignite mining for several years. The Chair of Wassertechnik & Siedlungswasserbau at the Brandenburg University of Technology Cottbus-Senftenberg/Germany has developed a subsurface rehabilitation method using microbial sulfate reduction over the [...]

Physical activity is essential to delaying cognitive decline and preventing cognitive impairment in older adults. We designed and implemented two-level 4Active intervention for older adults living in retirement communities. This study aimed to examine the effectiveness of the 4Active intervention in increasing physical activity and cognitive function in older adults. Fifty-eight eligible older adults with a mean age of 83.83 years (76.3% females) living in two retirement communities voluntarily participated in this [...]

This scoping review aims to review the effectiveness of yoga as a complementary intervention for improving mental health outcomes in the geriatric population globally. Yoga is practiced by millions worldwide. Since practitioners of yoga claim to have calmer minds and better psychological and physical health, this topic needs to be reviewed at length. There is a considerable treatment gap worldwide in treating mental disorders, especially in old age, and there is a shortage of low-cost, feasible, and acceptable prev [...]

Depression and mental health-related issues are increasingly prevalent in young adolescents and adults and so is the use of Complementary Therapies (CTs) to treat depression. Systematic reviews have found that, of all CTs, acupuncture, exercise, and the herbal remedy St John’s Wort have the greatest amount of evidence for efficacy in treating depression. We aimed to assess Mental Health Literacy (MHL) levels in the treatment of depression and Complementary Therapy’s (CT) usage in adolescents and adults. Surveys wer [...]

TiO2 photocatalyst was prepared using cellulase as a biotemplate through a hydrothermal process. The as-prepared catalyst was characterized based on physicochemical techniques and was used to remove As(III) from contaminated water. The cellulase templated TiO2 photocatalyst (TiO2-cellulase) had a large specific surface area, which reached 166.6 m2·g–1. It also had a strong oxidation ability and, thus, behaved well in both photocatalytic oxidation of As(III) and dark adsorption. The pH of the solution h [...]
