Bioaugmentation of Sewage Sludge with Trametes versicolor in Solid Phase Biopiles Produces Degradation of Pharmaceuticals and Affects Microbial Communities
(2012-10-02)The use of sludge (biosolids) in land application may contribute to the spread of organic micro pollutants as wastewater treatments do not completely remove these compounds. Therefore, the development of alternative strategies ... -
Bioavailability of in-feed tetracyclines is influenced to a greater extent by crude protein rather than calcium
(2014-12)Feed is a common vehicle for tetracycline administration in animal farming. However, veterinarians and farmers often overlook that common feed components, such as proteins and calcium, may interact with these drugs and ... -
Biochemical and biological characterization of Ecuadorian pitviper venoms (genera Bothriechis, Bothriopsis, Bothrops and Lachesis)

Biochemical and biological characterization of two serine proteinases from Colombian Crotalus durissus cumanensis snake venom
(2013-03-01)Two clotting serine proteinases, named Cdc SI and Cdc SII, were isolated and characterized for the first time from Colombian Crotalus durissus cumanensis snake venom. The enzymes were purified using two chromatographic ... -
Biochemical and pharmacological similarities between the venoms of newborn Crotalus durissus durissus and adult Crotalus durissus terrificus rattlesnakes
(1991)A comparative study was performed with the venoms of newborn Crotalus durissus durissus, adult Crotalus durissus terrificus and adult Crotalus durissus durissus snakes. Venom of newborn specimens of C.d. durissus is very ... -
Biochemical characterization and pharmacological properties of a phospholipase A2 myotoxin inhibitor from the plasma of the snake Bothrops asper
(1997-09-15)A protein that neutralizes the biological activities of basic phospholipase A2 (PLA2) myotoxin isoforms from the venom of the snake Bothrops asper was isolated from its blood by affinity chromatography with Sepharose-immobilized ... -
Biochemical characterization of the venom of Central American scorpion Didymocentrus krausi Francke, 1978 (Diplocentridae) and its toxic effects in vivo and in vitro
(2019)non-buthid venoms, for which knowledge is scarce. In this work, we characterized the venom of a Diplocentridae species, Didymocentrus krausi, a small fossorial scorpion that inhabits the Tropical Dry Forest of Central ... -
Biochemical Indicators of nutritional status and dietary intake in Costa Rican Cabécar Indian Adolescents
(2005-03)The purpose of this study was to determine the blood levels of selected nutritional status indicators and the dietary intake of Costa Rican Cabécar Indians aged 10 to 16 years. The results showed that 65% of the adolescents ... -
Biochemistry and toxicology of toxins purified from the venom of the snake Bothrops asper
(2009-12-01)The isolation and study of individual snake venom components paves the way for a deeper understanding of the pathophysiology of envenomings – thus potentially contributing to improved therapeutic modalities in the clinical ... -
Biodegradation of sulfamethazine by Trametes versicolor: Removal from sewage sludge and identification of intermediate products by UPLC–QqTOF-MS
(2011-11-15)Degradation of the sulfonamide sulfamethazine (SMZ) by the white-rot fungus Trametes versicolor was assessed. Elimination was achieved to nearly undetectable levels after 20 h in liquid medium when SMZ was added at 9 mg ... -
Biological and biochemical activities of Vipera berus (European viper) venom
(1993-06)Vipera berus is widely distributed throughout the northern part of Europe and Asia. Characterization of several toxic effects of its venom in the mouse, as well as of in vitro enzymatic activities was performed. Vipera ... -
Biological and proteolytic variation in the venom of Crotalus scutulatus scutulatus from Mexico
(2018-01)Rattlesnake venoms may be classified according to the presence/absence and relative abundance of the neurotoxic phospholipases A2s (PLA2s), such as Mojave toxin, and snake venom metalloproteinases (SVMPs). In Mexico, ... -
Biological and structural characterization of crotoxin and new isoform of crotoxin B PLA2 (F6a) from Crotalus durissus collilineatus snake venom
(2006)A new crotoxin B isoform PLA2 (F6a), from Crotalus durissus collilineatus was purified from by one step reverse phase HPLC chromatography using l-Bondapack C-18 column analytic. The new crotoxin B isoform PLA2 (F6a), ... -
Biophysical and Biochemical Comparison of Extracellular Vesicles Produced by Infective and Non-Infective Stages of Trypanosoma cruzi
(2021-05-13)Extracellular vesicles (EVs) are small lipid vesicles released by either any prokaryotic or eukaryotic cell, or both, with a biological role in cell-to-cell communication. In this work, we characterize the proteomes and ... -
