The use of ultrapure molecular hydrogen enriched with atomic hydrogen in apparatuses of artificial lung ventilation in the fight against virus COVID-19.

COVID-19 is a disease caused by the SARS-CoV virus. It stands for severe acute respiratory syndrome, which affects the lungs. The process of replication and progression of the COVID-19 virus causes the formation of an excessive amount of reactive oxygen species and inflammation. Many studies have been carried out that have demonstrated that hydrogen has strong anti-inflammatory properties. It reduces hypotension and other symptoms by reducing inflammation and oxidative stress. Oxygen mixture, enriched with Hydrogen, - helps to reduce the resistance of the respiratory tract and frees up access to the pulmonary alveolus, which improves the penetration of oxygen into the lungs. Since hydrogen is an antioxidant, it helps to reduce the burden on the immune system, helps to maintain the body's health and its ability to quickly recover. When electrolysers are used to produce an oxygen-hydrogen mixture, alkaline mist and other impurities can enter the patient's lungs and cause poisoning and chemical burns. For this reason, the use of atomic hydrogen obtained from metal hydride sources for ventilation of the lungs will be more effective for treating COVID-19 than a molecular hydrogen-oxygen mixture from an electrolyzer. A functional diagram of a metal hydride source of atomic hydrogen to an artificial lung ventilator is shown. It is possible to create a series of hydrogen storage tanks of various capacities.

The stress process of family caregiving in institutional settings.

PURPOSE: This study adapts the Stress Process Model (SPM) of family caregiving to examine the predictors of depression in a sample of caregivers (n = 133) with demented relatives residing in suburban skilled nursing facilities. DESIGN AND METHODS: We interviewed family caregivers of family members residing in skilled nursing homes using a variety of measures to assess primary stressors, secondary strain, nursing home stressors, and caregiver depression. We used block-wise regression analyses to determine the predictors of caregiver depression. RESULTS: Results indicated that positive resident adjustment to placement was best predicted by the closeness of the resident-caregiver relationship and nursing home stressors. Caregiver strain, resident adjustment, and nursing home stressors best predicted caregiver adjustment. In turn, the best predictors of caregiver depression included caregiver age, caregiver adjustment to the nursing home, and nursing home stressors. IMPLICATIONS: These results suggest that caregiver depression is closely linked to how well both the resident and caregiver adjust to the nursing home environment. Results also indicate that by broadening the SPM to include stressors common to the nursing home experience, researchers will be able to understand more clearly the specific components of the stress process that may lead to depression in family caregivers of persons living in nursing homes.

Deformation of liquid crystal droplets under the action of an external ac electric field.

Deformation of liquid crystal droplets suspended in liquid polymer matrix under the action of external electric field was observed in dependence of ion concentration in such system. Experimental dependence of droplet elongation vs electric field demonstrates nonmonotonous character with increase of ion concentration. The theory that provides the basic agreement with experimental observation is developed.
