Biomedical adhesives have been found to be an attractive alternative suturing in several circumstances. However, date most of the clinically approved formulations are based on synthetic and highly reactive toxic chemicals. In this work, we aimed combine for first time bioactive properties cationic polysaccharide chitosan its intrinsic electrostatic binding negatively charged tissues with biocom...

this study reports the synthesis of chitosan anchored schiff base, ([2-oxo-1h-indol-3-ylidene] amino) chitosan and its cu (ii) metal complex. the complex was characterized by elemental analysis, ft-ir spectrum, thermogravimetry analysis .the crystallinity of the compound was analyzed by powder x-ray diffraction technique. the catalytic efficiency of complex was studied in the oxidation of alcoh...

this article present the result from a study of two sediment cores collected from theenvironmentally distinct zones of ces. accumulation status of five toxic metals: cadmium (cd), chromium(cr), cobalt (co), copper (cu) and lead (pb) were analyzed. besides texture and chns were determined tounderstand the composition of the sediment. enrichment factor (ef) and anthropogenic factor (af) wereused ...

BACKGROUND Bothrops, Crotalus and Lachesis represent the most medically relevant genera of pitvipers in Central and South America. Similarity in venom phenotype and physiopathological profile of envenomings caused by the four nominal Lachesis species led us to hypothesize that an antivenom prepared against venom from any of them may exhibit paraspecificity against all the other congeneric taxa....

Aims: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are serious severe cutaneous adverse reactions with high mortality and morbidity induced by medications. In this cross sectional study, we investigated, suspected drugs, and potential treatments of SJS/TEN. Methods: A cross- sectional descriptive study was conducted on 60 patients admitted with a diagnosis of Stevens-Jo...

Mycotoxins severely threaten the health of humans and animals. For this reason, many countries have enforced regulations and recommendations to reduce the dietary exposure. However, even though regulatory actions must be based on solid scientific knowledge, many aspects of their toxicological activity are still poorly understood. In particular, deepening knowledge on the primal molecular events...
