Cytoprotective effects of the antioxidant phytochemical indicaxanthin in beta-thalassemia red blood cells

2006

Antioxidant phytochemicals are investigated as novel treatments for supportive therapy in beta-thalassemia. The dietary indicaxanthin was assessed for its protective effects on human beta-thalassemic RBCs submitted in vitro to oxidative haemolysis by cumene hydroperoxide. Indicaxanthin at 1.0-10 microM enhanced the resistance to haemolysis dose-dependently. In addition, it prevented lipid and haemoglobin (Hb) oxidation, and retarded vitamin E and GSH depletion. After ex vivo spiking of blood from thalassemia patients with indicaxanthin, the phytochemical was recovered in the soluble cell compartment of the RBCs. A spectrophotometric study showed that indicaxanthin can reduce perferryl-Hb ge…

Delayed onset muscle soreness (DOMS) management: present state of the art

2016

This paper reviews existing theories explaining the delayed onset muscle soreness (DOMS) phenomenon. The authors describe the main symptoms of DOMS and their relation to different kinds of training strategies, and discuss the most popular muscle pain reduction interventions such as stretching, diet, dietary supplements, nonsteroidal anti-inflammatory drugs (NSAIDs), cryotherapy and cold water immersion, concurrent training, and the repeated bout effect.

The Impact of the Progressive Efficiency Test on a Rowing Ergometer on White Blood Cells Distribution and Clinical Chemistry Changes in Paralympic Ro…

2017

Abstract There is a large gap in knowledge regarding research on post-exercise blood changes in disabled athletes. There are relatively few data on adaptive mechanisms to exercise in disabled athletes, including disabled rowers. Two rowers from a Polish adaptive rowing settle TAMix2x that qualified for the Paralympic Games in Rio, 2016 took part in this study. They performed a progressive test on a rowing ergometer until exhaustion. The cardiorespiratory fitness measures, complete blood count, white blood cells’ distribution and 30 clinical chemistry variables describing laboratory diagnostic profiles and general health were determined. The extreme effort induced changes in all studied meta…

CONSEQUENCES OF AAS DOPING: AN OVERVIEW OF SHORT AND LONG TERM EFFECTS

2012

AAS, if taken in overphysiological doses, may increase muscle strenght and lean body mass, while they don't seem to have effects on endurance performance and on fat mass. Because of the widespread use of these substances, the focus is on their related side effects. The effects on the reproductive system seem to be quite important and they may induce some changes as far as libido and (temporary) infertility are concerned. In recent years it has become clear that AAS can have significant impacts on psyche and behaviour. Researches and future studies should focus their attention primarily on the short and long term effects due to the discontinuous use of AAS and on the long term health effects…

Proanthocyanidins and Where to Find Them: A Meta-Analytic Approach to Investigate Their Chemistry, Biosynthesis, Distribution, and Effect on Human He…

2021

Proanthocyanidins (PACs) are a class of polyphenolic compounds that are attracting considerable interest in the nutraceutical field due to their potential health benefits. However, knowledge about the chemistry, biosynthesis, and distribution of PACs is limited. This review summarizes the main chemical characteristics and biosynthetic pathways and the main analytical methods aimed at their identification and quantification in raw plant matrices. Furthermore, meta-analytic approaches were used to identify the main plant sources in which PACs were contained and to investigate their potential effect on human health. In particular, a cluster analysis identified PACs in 35 different plant famili…

A new method to value efficiency of enzyme blends for pancreatic tissue digestion.

2010

Islet transplantation, since the 90’s, has been resulting to be one of the best successful example of human cell therapy. Nevertheless, islet isolation procedure is not completely standardized; in fact, more than fifty percent of islets procedures don’t arrive to their transplantation. This is due both to the variability of donor’s pancreas and to an unpredictable enzymatic blend efficiency. Enzymes used in pancreas digestion are extracted from Clostridium histolyticum bacteria and digest several substrates. In particular they have strong collagenolytic activity compared to vertebrate collagenases. However, several impediments persist in human islet isolation success probably due to the var…
