Hepatocellular carcinoma is one of the most common cancers in the world. Previously, we found that the level of glucocorticoid receptor was significantly higher in hepatocellular carcinoma than in adjacent liver tissues. Moreover, in vitro and in vivo studies showed that glucocorticoid stimulated the growth of hepatoma cells. On the other hand, endogenous metabolites such as 2-methoxyestradiol,...

The purpose of this study was to investigate the therapeutic effects of propolis on biochemical and microbiological parameters in muscle tissues of carp (Cyprinus carpio, Linnaeus 1758) exposed to arsenic. A sublethal concentration of arsenic (0.01 ppm) and/or 0.01 ppm propolis were administered to fish for seven days. Biochemical parameters [pH, lactic acid, total volatile basic nitrogen (TVB-...

Agricultural resources such as barley, wheat, and corn were hydrolyzed by commercial amylolytic enzymes and fermented into lactic acid by Enterococcus faecalis RKY1. Although no additional nutrients were supplemented to those resources, lactic acid productivities were obtained at >0.8 g/l h from barley and wheat. When 200 g/l of whole wheat flour was hydrolyzed by amylolytic enzymes after the p...

The consideration of the manner in which various metabolites are removed from the living cell by the process of oxidation presents a problem which, if it is to be considered quantitatively, necessitates a detailed knowledge of the course of comparable reactions in vitro. I t is, therefore, desirable to consider such reactions from many points of view before attempting to analyze the more compli...

Vegetables may be preserved by fermentation, direct acidification, or a combination of these, along with pasteurization, to yield products with an extended shelf life and enhanced safety.  Effect of lowering the pH, either by adding acid or lactic fermentation, on thermal process requirements for canned vegetables was investigated. Malic acid was preferred for acidification of canned vegetables...

The aim of this work was to study the fermentation of whey for the production of L(+) lactic acid using Lactobacillus casei. The effect of different process parameters such as pH of the medium, temperature, inoculum size, age of inoculum, agitation and incubation time was monitored to enhance the lactose conversion in whey to L(+) lactic acid. Fermentations were performed without any pH control...

For the first time lactic acid was applied as an efficient and green catalyst for the one-pot three-component synthesis of amidoalkyl naphthols via the condensation between arylaldehydes, 2-naphthol and amides or urea under thermal solvent-free conditions in good to excellent yields. We have demonestrated a mild and efficient eco-friendly tandem synthesis of amidoalkyl naphthols using lactic ac...

An environmentally friendly, green, and highly efficient process for the synthesis of biologically and pharmacologically  4H-benzo[b]pyrans  and  3,4-dihydropyrano [c] chromenes  is  developed  by condensing cyclic aromatic aldehydes, malononitrile, and dimedone or 4‐hydroxycoumarin in the presence  of  lactic  acid  as  an  efficient  and  green  catalyst.  The corresponding  products  have  b...

L. amylophilus GV6 was studied for production of L(+) lactic acid in single step fermentation using starchy substrates. Seven types of inexpensive organic nitrogen supplements (flour of pigeon pea, red lentil gram, black gram, bengal gram, green gram, soya bean and baker’s yeast) were evaluated for their potential to replace more expensive commercial nitrogen sources, peptone and yeast extract....
