Relati ve viscosities of some mineral salts viz; sodium sulphate, potassium sulphate, ammon ium sulpha te and magnes iu m sulphate, at di ffe rent concentrations have been determined in binary aqueous solutions of urea (mole-frac tions of urea, XII!""" = 0.0 10, 0.025 , 0. 040, 0.055 and 0.070) at 308. 15K and in XII!""" = 0.025 at di fferent temperatures. The data have been evaluated using l o...

Dehydroepiandrosterone sulphate is one of the most important neurosteroids. In the present paper, we studied the effect of dehydroepiandrosterone sulphate on persistent sodium currents and its mechanism and functional consequence with whole-cell patch clamp recording method combined with a pharmacological approach in the rat medial prefrontal cortex slices. The results showed that dehydroepiand...

Two bio salt minerals, potassium sulphate, sodium sulphate and a mixture of both bio salts at the effective concentration of 1% which were added to the mulberry leaves of silkworm B. mori L., to evaluate their effect on the differential haemocyte counts (DHC) and absolute differential haemocyte counts (ADHC). Daily changes of five haemocyte types were investigated as, prohaemocytes, plasmatocyt...

The purification and properties of a hyaluronate lyase secreted by Streptococcus agalactiae, which is believed to facilitate the invasion of host tissues by the organism, have been described previously [Pritchard, Lin, Willingham and Baker (1994) Arch. Biochem. Biophys. 315, 431-436]. The specificity of the limited cleavage of chondroitin sulphate by the enzyme is the subject of this report. To...

Two simple, accurate and precise methods are described for the determination of propranolol hydrochloride with cerium(IV) sulphate. The titrimetric method is based on the oxidation of the drug by a known excess amount of cerium(IV) sulphate and back titration of the unconsumed oxidant with ammonium ferrous sulphate. In the spectrophotometric method, the unreacted cerium(IV) sulphate is treated ...

natural organic wastes contain considerable amounts of nutritional elements. the availability and uptake of nutrient elements in soil) especially in alkali and calcareous soils) increase due to high content of organic matter, and reduce the micro-elements deficiencies. organic wastes have pathogenic contaminations that come from waste type and transmitted by microorganisms such as bacteria, fun...

The SLC51 organic solute transporter family of transporters is a pair heterodimeric proteins which regulate bile salt movements in the small intestine, duct, and liver, as part enterohepatic circulation [2, 5, 1]. OSTα/OSTβ also expressed steroidogenic cells brain adrenal gland, where it may contribute to steroid sulphate movement [6]. Bile acid transport suggested be facilitative independent s...

Interactions between fluorine (as F) and aluminum (as Al) have recently attracted much attention following reports of their possible involvement in Alzheimer’s disease (AD). An inverse correlation has been demonstrated between the incidence and severity of AD and the level of fluorine in drinking water.1-4 Aluminum has long since been implicated in the etiopathology of AD, and neurotoxicity stu...

BACKGROUND Interstital cystitis is often treated with exogenous glycosaminoglycans such as heparin, chondroitin sulphate (Uracyst), hyaluronate (Cystistat) or the semi-synthetic pentosan polysulphate (Elmiron). The mechanism of action is presumed to be due to a coating of the bladder surface to replace the normally present chondroitin sulphate and heparan sulphate lost as a result of the diseas...

Successful long-term bioremediation of mining-influenced water using complex organic matter and naturally-occurring microorganisms in sub-surface flow constructed wetlands requires a balance between easily and more slowly degrading material. This can be achieved by combining different types of organic materials. To provide guidance on what mixture combinations to use, information is needed on h...
