In this study, senescent cell distribution and quantity in vastus lateralis muscle were examined in young human adults after a single bout of resistance exercise. To determine the effects of dietary protein availability around exercise on senescent cell quantity and macrophage infiltration of skeletal muscle, two isocaloric protein supplements (14% and 44% in calorie) were ingested before and immediately after an acute bout of resistance exercise, in a counter-balanced crossover fashion. An additional parallel trial was conducted to compare the outcome of muscle mass increment under the same dietary conditions after 12 weeks of resistance training. The main findings of the study are as follows: 1) No senescent myofibers are detected in the skeletal muscle of young men aged between 20-25 y; 2) Most of the senescent cells found around muscle fibers are endothelial progenitor cells; 3) A single bout of resistance exercise reduces the senescent endothelial progenitor cells by 48% in challenged muscle and maintains at low levels for 48 hours; 4) Resistance exercise with low protein availability is associated with greater increases in macrophage infiltration and further depletion of senescent endothelial progenitor cells in muscle tissue during recovery, but prevents muscle hypertrophy for a long term. Taken together, these data suggest that senescence cell clearance and muscle mass increment are associated with the magnitude of muscle inflammation after resistance exercise,...

Publication date: May 2020Source: Clinica Chimica Acta, Volume 504Author(s): Damian Jacenik, Jakub FichnaAbstractChemerin is a multifunctional protein involved among others in adipogenesis, angiogenesis and lipid as well as glucose metabolism. Chemerin is an essential factor in promotion of chemotaxis of numerous immune cell types and plays an important role in several pathophysiologic conditions. Chemerin receptors are present on monocytes/macrophages, T cells, natural killer and dendritic cells as well as neutrophils. However, the role of chemerin and chemerin receptors in immune response and gastrointestinal diseases is...

ConclusionsPatients with CMS were more likely to present with increased comorbidities. Patients with CMS undergoing CABG were at risk for worse short ‐term secondary postoperative outcomes and reduced long‐term survival. The data supports the need for further investigation for risk reduction surrounding operative revascularization.

AbstractThe first successful human heart transplantation was reported on 3 December 1967, by Christiaan Barnard in South Africa. Since then this life ‐saving procedure has been performed in over 120 000 patients. A limitation to the performance of this procedure is the availability of donor hearts with as many as 20% of patients dying before a donor's heart is available for transplant. Today, hearts for transplantation are procured from indiv iduals experiencing donation after brain death (DBD). Interestingly, this, however, was not always the case as the first heart transplants occurred after circulatory dea...

AbstractCoarctation is rare in patients over 50 years of age; however, if present, it can be associated with complex intracardiac pathologies and represent a formidable surgical challenge. Herein, we report a single ‐stage approach for surgical repair of coarctation associated with aortic, mitral, and tricuspid valve pathology using an ascending‐to‐descending aortic bypass with posterior pericardial access.

Publication date: Available online 17 February 2020Source: Journal of Forensic and Legal MedicineAuthor(s): Roger W. ByardAbstractIn previous years individuals with tattoos were thought to have a higher rate of mental illness and risk taking behaviour. With the widespread adoption of tattoos in Western countries in recent years this negative association has been questioned. An issue which arises, however, is that “tattooing” is a heterogeneous activity that covers a wide spectrum of designs and motivations. To examine the characteristics of individuals presenting to medicolegal autopsy with “expletive tat...

Similar to many Termitidae, this species contains a mixed segment in the intestine, an anatomic distinct region composed of both mesenteric and proctodeal tissues. In Neocapritermes spp., a pair of intestinal protrusions referred to as mesenteric sacs are associated with the mixed segment. In the present study, with the aid of ...
