Lignocellulosic wastes are generally produced in huge amounts worldwide. Peach waste of these obtained from fruit juice industry was utilized as the substrate for laccase production by Pleurotus eryngii under solid state bioprocessing (SSB). Its chemical composition was determined and this bioprocess was carried out under stationary conditions at 28 °C. The effects of different compounds; coppe...

background and objectives: synthetic dyes are recalcitrant to degradation and toxic to different organisms. decolorization of textile wastewaters is one of the major concerns since last decades. physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. biological treatments can be more convenient. in the present study, an attempt has been made for d...

BACKGROUND & AIMS Polyphenols exert a variety of biological properties, including antioxidant, immunomodulatory and antigenotoxic effects. In a randomized crossover study in healthy men, we investigated the effects of orange juice and its major polyphenolic compound hesperidin on a panel of immune cell functions, including cytokine secretion by leukocytes, lytic activity of NK cells, and the Re...

Gentamicin, an aminoglycoside antibiotic used to treat severe bacterial infections, may cause acute renal failure. At therapeutic concentrations, gentamicin accumulates in lysosomes and induces apoptosis in kidney proximal tubular cells. In gentamicin-treated renal LLC-PK1 cells, acridine orange release from lysosomes, previously interpreted as lysosomal membrane permeabilization, precedes the ...

An attempt to synthesize a holmium sulfidotungstate using potassium polysulfides as reactive flux resulted in orange single crystals of K2[WS4], isotypic K2[MoS4] (orthorhombic; Pnma; a=935.10(3), b=694.22(2), c=1221.85(4) pm; Z=4). A similar obtain neodymium with sodium polysulfide yielded violet substance, which underwent hydrolysis yielding orange-yellow Na2[WS4] ⋅ 4 H2O (monoclinic, C2/c, a...

It is well known that eating fruits and vegetables lowers the risk of chronic diseases such as heart disease and cancer. The question of what is/are the active ingredient(s) is still unresolved. The initial hypothesis was that the antioxidant vitamins were responsible. However, recently the polyphenols have been investigated since they have been found to have beneficial properties such as being...
