BACKGROUND Bovine BSP5 is a multifunctional protein primarily involved in sperm capacitation. BSP5 consists of long N-terminal part followed by two similar and highly conserved fibronectin type II domains designated A and B. METHODS In order to assess the role of these domains in the sperm binding and capacitation processes, we created recombinant individual domains (N, A, B), series of overl...

Introduction Magnesium sulphate (MS), causes bronchodilation by inhibiting bronchial smooth muscle contraction, interferes with parasympathetic stimulation, and prevents acetylcholine release to axon terminals [1]. It reduces inflammation by inhibiting mast cell degranulation and reduces thromboxane, histamine and leukotrienes [2]. Some pediatric studies suggest that MS, b-2-agonists and steroi...

Purpose: To evaluate the effect of vitamin B-complex on the nephrotoxicity of gentamicin in an established rat model. Methods: Adult Swiss albino rats weighing 170±20g were divided into 4 groups of 4 rats each. Each group was given one of the following: placebo injection (Control), 80mg/kg of gentamicin sulphate alone or with 1.5ml/kg/3ml/kg body weight of vitamin B-complex (intramuscular) cont...

1. 3Hand 35S-labelled heparan sulphate was isolated from monolayers of human lung fibroblasts and subjected to degradations by (a) deaminative cleavage and (b) periodate oxidation/alkaline elimination. Fragments were resolved by geland ion-exchangechromatography. 2. Deaminative cleavage of the radioactive glycan afforded mainly disaccharides with a low content of ester-sulphate and free sulphat...

The metabolic fate of potassium dodecyl [(35)S]sulphate was studied in rats. Intraperitoneal and oral administration of the ester into free-ranging animals were followed by the excretion of the bulk of the radioactivity in the urine within 12hr., approximately 17% being eliminated as inorganic [(35)S]sulphate. Similar results were obtained in experiments in which potassium dodecyl [(35)S]sulpha...

Chemical and spectroscopic studies have shown that in agricultural soils most of the soil sulphur (>95%) is present as sulphate esters or as carbon-bonded sulphur (sulphonates or amino acid sulphur), rather than inorganic sulphate. Plant sulphur nutrition depends primarily on the uptake of inorganic sulphate. However, recent research has demonstrated that the sulphate ester and sulphonate-pools...

Proton/sulphate co-transport in the plasma membrane of root cells is the first step for the uptake of sulphate from the environment by plants. Further intracellular, cell-to-cell and long-distance transport must fulfil the requirements for sulphate assimilation and source/sink demands within the plant. A gene family of sulphate transporters, which may be subdivided into five groups, has been id...

The present work was conducted to find out the effect of biofertilizer formulated with four species of bacteria (two species of Azotobacter and two species of Lysobacter) and zinc sulphate. Field experiments with mustard plant were conducted to study the effectiveness of soil application of zinc sulphate and biofertilizer at 0, 10, 20, 30, 40, 50 days after sowing. Plant height and condition of...
