TL;DR: A recent review as mentioned in this paper provides an up-to-date overview on selenium in infectious diseases caused by viruses (e.g., HIV, IAV, hepatitis C virus, poliovirus, West Nile virus) and bacteria (i.e., M. tuberculosis, Helicobacter pylori).

TL;DR: In this paper, the contents of international journals of parasitology dealing with broader topics inside this field show that rather a few papers appear with studies in the discipline of arachno-entomology.
Abstract: Considering the contents of international journals of parasitology dealing with broader topics inside this field show that rather a few papers appear with studies in the discipline of arachno-entomology In the journals Journal of Parasitology, Parasitology Research and Trends in Parasitology, the relations of published papers on protozoology, helminthology and arachno-entomology showed that in all three journals, papers on protozoans were the most common, while those on helminths of any kind reached the second place being rather as common as the protozoan papers in Parasitology Research and in the Journal of Parasitology In Trends of Parasitology, however, the papers on helminths reached only about 25% of the numbers published on protozoan topics But in all three journals—and this is important—the papers on arachno-entomological themes were scarce reaching less than the half of the protozoan papers in Parasitology Research, and only about 15% in the Journal of Parasitology and in the Trends of Parasitology These disproportions between the three great subdivisions of targets in the focus of parasitological research are dangerous, since this lack exists already for several decades and thus led to a backlog of unsolved increasing problems that are caused by ticks, mites, insects and/or parasitic crustaceans especially in times of intensive globalization and global warming Studies on the biology, vectorship, invasion and spreading of wanted vectors and on the control of pests and parasites belonging to the field of arachno-entomology are urgently needed

TL;DR: It can be concluded that purslane is a promising natural product, which could be useful for the prevention of cardiovascular, neurodegenerative and other chronic diseases caused by oxidative stress.
Abstract: Aqueous juice from purslane ( Portulaca oleracea ) was screened for its antioxidant activity in adult male Waster albino rats. The antioxidant activity was determined by measuring reduced glutathione, catalase, superoxide dismutase, glutathione reductase, glutathione-S-transferase and glutathione peroxidase, as well as the inhibition in lipid peroxidation, nitric oxide in liver, kidney and testis of rats. Liver and kidney function were also determined. Administered rats with aqueous juice of purslane, resulted in marked improvement in all studied parameters. On the basis of the above results, it can be concluded that purslane is a promising natural product, which could be useful for the prevention of cardiovascular, neurodegenerative and other chronic diseases caused by oxidative stress.

TL;DR: It is suggested that SeNPs can alleviate hyperglycemia and hyperlipidemia in streptozotocin-induced diabetic rats, possibly by eliciting insulin-mimetic activity.
Abstract: The study was designed to investigate the anti-hyperglycemic activity of selenium nanoparticles (SeNPs) in streptozotocin-induced diabetic rats. Fifty-five mg/kg of streptozotocin was injected in rats to induce diabetes. Animals either treated with SeNPs alone or with insulin (6 U/kg) showed significantly decreased fasting blood glucose levels after 28 days of treatment. The serum insulin concentration in untreated diabetic animals was also enhanced by SeNPs. The results demonstrated that SeNPs could significantly decrease hepatic and renal function markers, total lipid, total cholesterol, triglyceride and low-density lipoprotein cholesterol levels, and glucose-6-phosphatase activity. At the same time, SeNPs increased malic enzyme, hexokinase and glucose-6-phosphate dehydrogenase activity, liver and kidney glycogen contents, and high-density lipoprotein cholesterol levels. In addition, SeNPs were able to prevent the histological injury in the hepatic and renal tissues of rats. However, insulin injection also exhibited a significant improvement in diabetic animals after 28 days of treatment. This study suggests that SeNPs can alleviate hyperglycemia and hyperlipidemia in streptozotocin-induced diabetic rats, possibly by eliciting insulin-mimetic activity.

TL;DR: Pits visualized in the PMD surface conformed to bacterial shapes suggesting active hydrolysis of the hydrocarbon polymer, implying that plastic serves as a novel ecological habitat in the open ocean.
Abstract: Plastics are the most abundant form of marine debris, with global production rising and documented impacts in some marine environments, but the influence of plastic on open ocean ecosystems is poorly understood, particularly for microbial communities. Plastic marine debris (PMD) collected at multiple locations in the North Atlantic was analyzed with scanning electron microscopy (SEM) and next-generation sequencing to characterize the attached microbial communities. We unveiled a diverse microbial community of heterotrophs, autotrophs, predators, and symbionts, a community we refer to as the “Plastisphere”. Pits visualized in the PMD surface conformed to bacterial shapes suggesting active hydrolysis of the hydrocarbon polymer. Small-subunit rRNA gene surveys identified several hydrocarbon-degrading bacteria, supporting the possibility that microbes play a role in degrading PMD. Some Plastisphere members may be opportunistic pathogens (the authors, unpublished data) such as specific members of the genus Vib...
