Identification of chemical constitutes present in these two SG60 fractions was carried out with a thin-layer chromatography (TLC) and a lichen metabolite database (Wintabolites). The two fractions (SG60-5 and SG60-6) were found to contain compounds belonging to the chemical families depsides, depsidones, anthraquinones, and xanthones. KU0060648 The SG60-5 and SG60-6 fractions were further fractionated with Sephadex LH-20. Over 15% of the 46 LH-20 fractions obtained from the SG60-5 fraction caused 100% cell death, whereas 32% of the LH20 fractions derived from SG60 6 fraction reduced cell survival to below 20%. Further investigations are underway to reveal the full biopharmaceutical potential of U. muhlenbergii.

Atherosclerosis accounts for upwards of 70% mortality in patients with type 2 diabetes and is also a chronic condition that causes atrial stenosis due to a lipometabolism imbalance. The purpose of this article is to consider the inflammatory factors implicated in atherosclerosis and their role in the development and progression of this vascular disease. The inflammasome signaling pathway is an important inflammatory mechanism involved in the development of atherosclerosis. The most important inflammasome pathway in this respect is NLRP3 inflammasome (Nucleotide-binding oligomerization domain (NOD)-like receptor with a pyrin domain 3), whose activation leads to the generation of important inflammatory cytokines including interleukins 1β and 18 (IL-1β and 18). The activities of these mature cytokines and inflammatory factors produced by other inflammatory pathways, lead to arterial inflammation and eventually arterial occlusion, which can result in life-threatening complications such as myocardial infarction and stroke. Therefore, it is essential to seek out more precise mechanisms for activation of inflammasomes and other inflammatory pathways for the development of therapeutic strategies of atherosclerosis.

MicroRNA-126 plays a critical role in angiogenesis via regulating the proliferation, differentiation, migration, and apoptosis of angiogenesis related cells such as endothelial cells, vascular smooth muscle cells and pericytes. OBJECTIVE The aim of this review is to investigate the molecular mechanisms and effects of microRNA-126 in angiogenesis process in pathophysiological conditions. METHODS To conduct this review, related articles published between 2001 and 2019 were collected from the PubMed, Web of Science, Google Scholar, Scopus and Scientific Information Database using search terms such as microRNA-126, angiogenesis, cardiovascular dseases with insufficient angiogenesis. So it is critical to understand its role in governing angiogenesis during pathological and even physiological conditions.

Bisphosphonates (BPs) are now the principal class of medications used for osteoporosis. OBJECTIVE To demonstrate the effect of BPs on treating osteoporosis after SCI. METHODS A comprehensive search in the PubMed, EMBASE, Web of Science and Cochrane Central databases was undertaken for randomized controlled trials (RCTs) exploring the effect of BPs on osteoporosis after SCI. The primary outcome measures were the BMD of different locations, serum bone turnover marker levels, serum biochemistry marker levels and adverse effect (AE) risks. The final search was performed in September 2019. RESULTS Six RCTs were included. A total of 147 patients met the inclusion criteria. BPs were found to statistically prevent bone loss in the total hip, femoral neck and trochanter at the 6- and 12-month follow-up points and to increase the BMD of the lumbar spine at the 12-month follow-up time point. BPs had no clear effect on serum PINP or serum calcium levels at the 12-month follow-up time point. CONCLUSION BP therapy may prevent bone loss in the lumbar spine and hip when administered early after SCI and has relatively high safety.

Besides its well-known activity on arrhythmias, its usefulness in the treatment of myotonia, myotonic distrophy and amyotrophic lateral sclerosis is now widely recognized. Nevertheless, it has been retired from the market in several countries because of its undesired effects. Thus, several papers were reported in the last years about analogues and homologues of mexiletine being endowed with a wider therapeutic ratio and a more selectivity of action. Some of them showed sodium channel blocking activity higher than the parent compound. It is noteworthy that mexiletine is used in therapy as a racemate even though a difference in the activities of the two enantiomers were widely demonstrated, with (-)-(R)-enantiomer being more active this finding led several research groups to study mexiletine and its analogues and homologues in their optically active forms. This review summarizes the different synthetic routes used to obtain these compounds. They could represent an interesting starting point to new mexiletine-like compounds without common side effects related to the use of mexiletine.
