Anti-inflammatory, anti-oxidant and anti-ulcer activities of aqueous lyophilizate of (Bignoniaceae).

Objectives: This work was carried out with a view to determining the antioxidant, anti-inflammatory and anti-ulcer properties of the aqueous lyophilized extract of .

Methods: proteinases inhibition, albumin denaturation, hemolysis of red blood cells by heat, inhibition of the proton pump H/KATPase, FRAP (Ferric reducing antioxidant power) and DPPH (1,1-diphenyl-2-picrylhydrazyl) assays were performed. , cold water immersion-induced ulceration and methylene blue-induced ulceration was used to determine the anti-ulcer properties of the lyophilizate (100, 200 and 300 mg/kg).

Species climatic niche explains post-fire regeneration of Aleppo pine (Pinus halepensis Mill.) under compounded effects of fire and drought in east Spain.

Fire and drought are two major agents that shape Mediterranean ecosystems, but their interacting effects on forest resilience have not been yet fully addressed. We used Pinus halepensis to investigate how compound fire-drought regimes determine the success of post-fire regeneration. We measured the density of P.

Copper Content and Resistance Mechanisms in the Terrestrial Moss Ptychostomum capillare: A Case Study in an Abandoned Copper Mine in Central Spain.

We present a case study on the tissue absorption of copper of a widely distributed moss species, Ptychostomum capillare in the polluted soil of an abandoned copper mine in central Spain. We studied the soil properties in a copper soil pollution gradient and sampled the moss tufts growing on them in four plots with contrasted soil copper levels. We determined the copper content in the soil and in the moss tissues.

Effect of oseltamivir on catecholamines and select oxidative stress markers in the presence of oligoelements in the rat brain.

The effect that osteltamivir has on the metabolism of catecholamines and oxidative damage in the brains of young patients remains unclear. The purpose of this study was to measure the effects of oseltamivir, in the presence of oligoelements, on biogenic amines and select oxidative biomarkers in the brains of uninfected, young rats under normal conditions. The study was conducted using male Wistar rats intraperitoneally treated for three days with either a control dose of 0.
