Sex Influence on Autophagy Markers and miRNAs in Basal and Angiotensin II-Treated Human Umbilical Vein Endothelial Cells.

Cardiovascular diseases (CVD) display many sex and gender differences, and endothelial dysfunction, angiotensin II (Ang II), and autophagy represent key factors in the autophagic process Therefore, we studied whether Ang II modulates the mentioned processes in a sex-specific way in HUVECs obtained from healthy male and female newborns. In basal HUVECs, the Parkin gene and protein were higher in FHUVECs than in MHUVECs, while the Beclin-1 protein was more expressed in MHUVECs, and no other significant differences were detected. Ang II significantly increases LAMP-1 and p62 protein expression and decreases the expression of Parkin protein in comparison to basal in MHUVECs.

Moderate red wine intake and cardiovascular health protection: a literature review.

Wine is a complex matrix consisting primarily of water (86%) and ethyl alcohol (12%), as well as other different molecules, such as polyphenols, organic acids, tannins, compound minerals, vitamins and biologically active compounds which play an important role in the specific characteristics of each wine. According to the Dietary Guidelines for Americans 2015-2020, moderate red wine consumption-defined as up to two units of alcohol per day for men and up to one unit of alcohol per day for women-significantly reduces the risk of cardiovascular disease which represents the major causes of mortality, and disability, in developed countries. We reviewed the available literature concerning the potential relationship between moderate red wine consumption and cardiovascular health.

miRNAs as biomarkers of musculoskeletal pain in long-distance runners: the MiMuS study protocol.

miRNAs are involved in the generation and progression of musculoskeletal pain, a condition that causes significant clinical, economic and social burden. In runners, the presence of musculoskeletal pain related to an inflammatory state or ongoing underlying tissue damage may result in poor training ability and performance. This study aims to evaluate the association between circulating and salivary miRNAs and pain in runners with and without musculoskeletal pain and to observe whether dysregulated miRNAs can distinguish between responders and nonresponders to a kinesiological intervention.

Antibacterial Activity on Orthopedic Clinical Isolates and Cytotoxicity of the Antimicrobial Peptide Dadapin-1.

In orthopedic surgery, biomaterial-associated infections represent a complication of serious concern. Most promising strategies to prevent these infections currently rely on the use of anti-infective biomaterials. Desirably, in anti-infective biomaterials, the antibacterial properties should be achieved by doping, grafting, or coating the material surfaces with molecules that are alternative to conventional antibiotics and exhibit a potent and highly specific activity against bacteria, without altering the biocompatibility.

Spectrophotometric analysis of post-mortem lividity: A new objective measure to define time of death.

The correct definition of time of death often represents a key to solving judicial cases. One of the methods for determination of the time interval since death is at present the quantitative and qualitative characteristics of hypostases. However, the simple observation of the degree and fixation of hypostases is based on nonobjective parameters, and is therefore characterized by an intrinsic variability that can compromise their reliability.

Cerebral venous sinus thrombosis after COVID-19 vaccination and congenital deficiency of coagulation factors: Is there a correlation?
