The maximal oxygen uptake (VO2max) constitutes an indicator of an organism's capacity to integrate oxygen into the metabolism to obtaining energy. The aim of this study was to determine the relationship between VO2max and oxidative stress (OxS) and chronic inflammation in the elderly individuals. A cross-sectional and exploratory study was conducted in a sample of 52 older persons. We measured plasma lipid peroxides (LPO), red blood cell glutathione peroxidase, red blood cell superoxide dismutase, and total antioxidant status...

In Mexico more than 40% of reported snakebites are due to rattlesnake species. In general, the venoms of these snakes are characterized by the presence of highly enzymatic components that could provoke coagulopathies, local and systemic tissue damage and some cases neurotoxicity. In northwestern Mexico (Baja California Peninsula, Gulf of California and Pacific islands), 15 species of Crotalus are distributed. Such a biodiversity implies a high variability in venom compositions that in turns would results in high variability in clinical manifestations...

Two cases of children diagnosed with renal tubular acidosis (RTA) associated with autoimmune hypothyroidism are presented. Case 1 developed an intestinal ileus at the age of five in the context of a respiratory problem. The tests performed confirmed metabolic acidosis, hyperchloraemia, hypokalaemia and nephrocalcinosis. Case 2 was diagnosed with hypothyroidism at the age of 11, and with RTA two years later. In both patients, the diagnosis of RTA was verified when decreased maximum urinary pCO2 was found. In case 2, a proximal bicarbonate leak (type 3 RTA) was also confirmed...

Currently available treatment options for non-infectious scleritis, including non-steroidal anti-inflammatory drugs, systemic corticosteroids and immunosuppressive therapies, have both efficacy and side effect limitations. Iontophoretic delivery of corticosteroids has been demonstrated to be effective for anterior uveitis and represents a potential new approach to scleritis therapy. We hypothesised that iontophoretic delivery would provide effective and precise medication delivery to the sclera, while limiting systemic exposure and side effects...
