Since 1970 acyclovir (ACV) has been the reference drug in treating herpes simplex virus (HSV) infections. However, resistant herpes simplex virus type 1 (HSV-1) strains have emerged, narrowing the treatment efficacy. The antiviral activity of classical Na, K ATPase enzyme (NKA) inhibitors linked the viral replication to the NKA's activity.

Lipases comprise the third most commercialized group of enzymes worldwide and those of microbial origin are sought for their multiple advantages. Agro-industrial waste can be an alternative culture medium for producing lipases, reducing production costs and the improper disposal of waste frying oil (WFO). This study aimed to produce yeast lipases through submerged fermentation (SF) using domestic edible oil waste as inducer and alternative culture medium.

Broth microdilution and checkerboard methods were used to evaluate the individual and combined activity with fluconazole and itraconazole (ITRA). The antibiofilm effect of the oil was assessed in 96-well plates alone and combined with ITRA and NAC, and cytotoxicity determined by MTT.

Background: Hemodialysis (HD) per se is a risk factor for thrombosis. Considering the growing body of evidence on blood-flow restriction (BFR) exercise in HD patients, identification of possible risk factors related to the prothrombotic agent D-dimer is required for the safety and feasibility of this training model. The aim of the present study was to identify risk factors associated with higher D-dimer levels and to determine the acute effect of resistance exercise (RE) with BFR on this molecule.

The treatment of severe musculoskeletal injuries, such as loss of bone tissue and consolidation disorders, requires bone transplantation, and the success of this bone reconstruction depends on the grafts transplant's osteogenic, osteoconductive, and osteoinductive properties. Although the gold standard is autograft, it is limited by availability, morbidity, and infection risk. Despite their low capacity for osteoinduction and osteogenesis, decellularized bone allografts have been used in the search for alternative therapeutic strategies to improve bone regeneration.

Home-based programs showed to be as effective and less costly than centre-based ones and might address those obstacles. Whether the evidence from international studies can be applied to our population is still unclear.

This study evaluates the relationship between cardiovascular events and pharmacological treatment for Type II Diabetes Mellitus (T2DM).
Methods: We recruited 227 individuals, 191 with T2DM (EG) and 36 pre-diabetics (CG), with a mean age of 70.
Introduction: Faced with lockdowns, it was mandatory the development of supervised home-based RT protocols to keep patients with chronic kidney disease engaged in programs. Nonetheless, there is a lack of scientific literature regarding its effects on patients.
Purpose: To investigate the effects of a supervised home-based progressive resistance training program on functional performance, bone mineral density, renal function, endothelial health, inflammation, glycemic homeostasis, metabolism, redox balance, and the modulation of exerkines in patients with CKD in stage 2.

Prior to clinical use, the corrosion resistance of new prosthesis system must be verified. The fretting-corrosion mechanisms of total hip arthroplasty (THA) implants generate metal debris and ions that can increase the incidence of adverse tissue reactions. For cemented stems, there are at least two interfaces that can be damaged by fretting-corrosion: stem-head and stem-cement.

Muscle weakness is associated with negative outcomes, in addition to being related to the pathogenesis of frailty and functional disability in the older individuals. Muscle strength and functionality are considered biomarkers of aging. Progressive resistance training (PRT) is a type of training that has been the subject of studies as it presents itself as a therapeutic option to fight the reduction of muscle strength and functionality in older individuals.

Anemia is an inherent complication of older individuals with end-stage renal disease (ESRD) that is associated with inflammation which in turn is an important factor in the activation of hepcidin that contributes to the decrease in serum iron. Athough resistance training (RT) seems to reduce inflammation in ESRD, its influence on hepcidin and iron availability in hemodialysis patients is unclear. Therefore, the aim of this study was to exemine the effects of RT in on inflammatory profile, hepcidin, and iron status in older individuals with ESRD.
