The present need for an energy transition in the wake of a global climate catastrophe led to the “EU green deal” which requires a transition of the energy system in all countries. This study aimis survey aims to identify strategies within such an energy transition based on global trend analyses and reports on available technologies for implementation. Based on a literature analysis of over 300 pieces (of feasibility studies and technology implementation reports with a focus on Central Europe) and a statistical anal [...]

A range of corrective surgical procedures may be required in adult renal transplant recipients who sustain loss of integrity of the abdominal wall in the first month postoperatively. Where this involves the fascia, such as in acute fascial dehiscence or in renal allograft compartment syndrome, more sophisticated reconstructive procedures may also be required, particularly in the setting of surgical site infection. There is limited data on the use of prosthetic or biologic mesh for this type of scenario, where urgen [...]

In the recent past, laser therapy has made immense progress as it is known to change microcirculation, modulate vegetative parameters, and stimulate mitochondrial activity in the human body. This editorial briefly describes a new laser watch prototype (generation 2021), which can be used to perform continuous and simultaneous blood irradiation at the radial and/or ulnar artery of the wrist with different wavelengths of laser light. In a preliminary measurement, the increase in regional oxygen saturation at the croo [...]

Flows in multi-branch piping systems are modeled for linear Newtonian and nonlinear Power Law, Bingham Plastic and Herschel-Bulkley fluids. The nonlinear models are often used to describe multiphase fluids consisting of liquid and solid phases, including cement slurries and drilling muds in petroleum engineering. Rheological and heterogeneous multiphase effects are important to blood flows in single and bifurcated arteries, capillaries and veins – biological applications are also emphasized to highlight their incre [...]

Anthropometric measurements are frequently used to assess changes in body composition in different populations. Despite being a cheap, in-field, and relatively valid technique, the COVID-19 pandemic has impulse research on digital anthropometry across the globe. Machine learning, as the convergence of artificial intelligence and data mining, has the potential to improve data collection and analysis in the applications of kinanthropometry. Far from replacing conventional methods, digital anthropometry is a powerful [...]

Background: The present study evaluates the effects of selective directed forgetting (SDF) and directed forgetting (DF) on subsequent memory retrieval and investigate whether acute exercise can facilitate the effects of SDF. Methods: A four-arm (n=20 per group; N=80; Mage=20 yrs), parallel-group, randomized controlled experiment was employed. The four groups included: 1) exercise plus SDF (Ex+SDF), 2) SDF only (SDF), 3) DF only (DF) and 4) R (remember) only (R). Participants viewed two separate word lists (list 1 a [...]

The growing population of older adults with depression is a significant public health concern, and effective treatments are necessary. Mindfulness meditation intervention offers effective treatment for depression, but little research has been conducted on the older population. This study aimed to evaluate if the combination of the Internet Mindfulness Meditation Intervention (IMMI) plus iMINDr application improves well-being in older adults with depressive symptoms. Potential participants were recruited online. IMM [...]

Oxidative stress in cerebral ischemia/reperfusion injury (CIRI) involves reactive oxygen and nitrogen species (ROS and RNS). Despite efficient antioxidant pathways in the brain, hypoxia triggers the production of oxygen free radicals and downregulates ATP, which leads to oxidative stress. Sources of free radicals during CIRI include Ca2+-dependent enzymes, phospholipid degradation and mitochondrial enlargement. Upon reperfusion, the abrupt increase of oxygen triggers a massive radical production via enzymes like xa [...]

Due to the insidious progression of Alzheimer's disease and related dementias (ADRD), surrogate decision-makers typically make medical and long-term-care decisions for a care recipient, most often a family care partner. Unfortunately, many care recipient/care partner dyads have failed to engage in advance care planning or have lost the opportunity to do so due to the cognitive decline of the care recipient. To address this need, our team created a validated dementia-focused advance care planning tool known as t [...]

The incidence of vascular diseases among caregivers of dementia patients is high, and one potential cause is the exacerbation of blood coagulability due to mental strain from caregiving. This study aimed to examine the effects of aerobic exercise on blood coagulability, from the perspective of improving the health of caregivers. Thirty-one healthy elderly caregivers, residing with patients suffering from Alzheimer’s-type dementia, were randomly divided into two groups. In the intervention group, moderate walk [...]
