Individuals with dementia frequently report poor quality of life (QOL), which declines as their disease progresses. Some evidence suggests that physical activity may help maintain cognitive function in older age, but it is unclear whether physical activity affects quality of life in older adults with dementia. The purpose of this review paper is to explore whether and how physical activity impacts QOL in patients with diagnosed dementia in different residential settings. To conduct this systematic review, the follo [...]

The process of light-induced C-H oxygenation is of high interest as it can be used for the construction of oxygenated compounds. Herein, we report a mild and general method for the efficient synthesis of aromatic ketones following the process of metal-free C-H oxygenation. With air as the oxidant, high functional tolerance was demonstrated, and the desired ketones were obtained in moderate to excellent yields at room temperature (25 oC). Mechanistic studies suggested that the oxidative transformation potentially oc [...]

Lignin is the most abundant renewable source of aromatics on earth, and conversion of it to chemicals and fuels is needed to build an economically viable renewable biofuels industry. Biological routes to converting lignin to fuels and chemicals involve depolymerizing lignin using lignin-degrading enzymes that catalyze the breaking of ether and carbon-carbon bonds in the phenolic and non-phenolic subunits of lignin. Laccases are a crucial class of lignin-degrading enzymes and are copper-containing enzymes capable of [...]

Metabolic syndrome (MetS) is considered a risk factor for erectile dysfunction (ED), and ED is almost three times more prevalent in men with MetS. Vascular pathologies are a significant factor for the development of ED, and many experts suggest endothelial dysfunction (EnD) as a likely explanation for the association between ED and MetS. Studies also show that corporal vascular and trabecular smooth muscle dysfunction leads ultimately to corporal veno-occlusive dysfunction. Different functional system abnormalities [...]

By virtue of its connections to a myriad of other clocks located both in the brain and in peripheral organs and cells, this clock provides a timing signal based on the light/dark cycle by which organismal physiology and behaviour are governed. Disturbances of these natural rhythms have multiple downstream effects, frequently resulting in dysregulations of sleep and wake cy [...]

Objective: The purpose of this study was to evaluate the common locations of perihepatic fluid collections after liver transplantation, assess their complexity, and understand their natural history and clinical significance. Materials and Methods: A retrospective analysis of 189 postoperative orthotopic liver transplant patients with a mean age 49.6 years was performed using serial CT or MRI to characterize perihepatic fluid collections. Location, size, complexity of the collections, and clinical course were evalua [...]

Cryptic balanced chromosomal aberrations can be an underlying cause of infertility. In 2003 Cockwell and coworkers highlighted the relevance of euchromatic pericentric regions of acrocentric chromosomes that may be a yet ignored genomic region hosting cryptic rearrangements. Here we offer the first follow-up study to further explore this idea. Two specific molecular cytogenetic probe sets were established to elucidate such cryptic rearrangements together with chromosomal heteromorphisms of acrocentric centromeres. [...]

Invasive fungal disease (IFD) is a significant contributor to morbidity and mortality in pediatric patients undergoing hematopoietic stem cell transplantation (HSCT). Early detection and timely initiation of antifungal therapy is important for improved outcome, but diagnosis remains difficult, especially when relying on conventional microbiology methods such as culture and microscopy. Data on the use of fungal biomarkers for screening and diagnosis of IFD in HSCT pediatric patients are limited, precluding the devel [...]
