Introduction Methylsulfonylmethane (MSM), also known as dimethyl sulfone (DMSO 2 ) and methyl sulfone, is an organic sulfur-containing compound that occurs naturally in a variety of fruits, vegetables, grains, and animals including humans. A white, odorless, slightly bitter-tasting crystalline substance containing 34-percent elemental sulfur, MSM is a normal oxidative metabolite product of dime...

The aim of this work was to verify if chronic administration of the hydroalcoholic extract of stems from Equisetum arvense (HAE) reverses the cognitive impairment in aged rats, as well as, evaluates it in vitro antioxidant properties. Chronic administration of HAE at dose of 50 mg/kg, i.p., improved both short- and long-term retention of inhibitory avoidance task and ameliorated the cognitive p...

The use of high pH anion exchange chromatography combined with pulsed amperometric detection has been established as an effective and sensitive method for the separation, detection and quantification of monosaccharides from a wide range of sources. However, careful examination of the separation conditions required is necessary to ensure that a complete monosaccharide profile can be determined f...

Over 400tons of Pb enters Swiss soils annually at some 2000 military shooting ranges (MSRs). We measured elements in the leaves of 10 plant species and associated rhizospheric soil on the stop butt of a disused MSR. The geometric mean concentrations of Pb, Sb, Cu, Ni in rhizospheric soils were 10,171mg/kg, 5067mg/kg, 4125mg/kg and 917mg/kg. Some species contained Pb, Cu and Ni, above concentrat...

The hypoglycemic effect of a water extract from aerial parts (0.33 g/kg) of Equisetum myriochaetum Schlecht and Cham (Equisetaceae) was analyzed in 11 recently diagnosed type 2 diabetic patients. A single dose of this extract was orally administered. Glucose and insulin were determined at 0, 30, 60, 90,120 and 180 min after administration. The same patients served as the control group and recei...
