The present study aimed to investigate the role of yeast extract and silver nitrate on the enhancement of phenylpropanoid pathway genes and accumulation of rosmarinic acid in Agastache rugosa cell cultures. The treatment of cell cultures with yeast extract (500 mg/L) and silver nitrate (30 mg/L) for varying times enhanced the expression of genes in the phenylpropanoid pathway and the production...

In this study, the culture medium and fermentation modes were studied aiming to improve cell density of Bacillus clausii. Firstly, factorial design method using Minimum Run Resolution IV was used evaluate relative importance components growth The results showed that three peptone, yeast extract malt significantly affecting bacterial biomass. Then, optimization these ingredient concentrations a ...

Factor and multiple regression analysis were used to extract the morphometric variables that contributed to feeding success in three small freshwater fishes. Of the first two factors, factor 1, showed high loading of gut weight (GW), length of the upper (UJ), and lower jaws (LJ) in mola, Amblypharyngodon mola (Hamilton), and GW and vertical mouth opening (VMO) in punti, Puntius ticto (Hamilton)...

Background: In Algeria the date wastes production is estimated at least 85.000 tones. Date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced. Objective: The aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. Materia...

Herpesvirus glycoprotein complex gH/gL provides a core entry function through interactions with the fusion protein gB and can also influence tropism through receptor interactions. The Epstein-Barr virus gH/gL and gH/gL/gp42 serve both functions for entry into epithelial and B cells, respectively. Human cytomegalovirus (HCMV) gH/gL can be bound by the UL128-131 proteins or gO. The phenotypes of ...

This article reports on the bioactivities of citrus extracts (citrus extract, lemon extract, and neroli) toward Saccharomyces cerevisiae, Zygosaccharomyces bailii, Zygosaccharomyces rouxii, Pichia membranifaciens, and Rhodotorula bacarum. The bioactivities of the extracts (from 10 to 100 ppm) were evaluated through a microdilution method; thereafter, citrus extracts (0 to 80 ppm) were tested in...

We refute a recent claim in the literature of a " new " quantum deformation of GL(2). Until the year 2000 it was not clear how many distinct quantum group deformations are admissible for the group GL(2) and the supergroup GL(1|1). For the group GL(2) there were the well-known standard GL pq (2) [1] and nonstandard (Jordanian) GL gh (2) [2] two-parameter deformations. (The dual quantum algebras ...

Wintrobe (1) recently stated that certain patients with typical pernicious anemia could be thrown into complete remission by oral treatment with dried, unautolyzed yeast, and he concluded that there was in the yeast some hematopoietic factor specific for the disease. As further argument for this belief, he stated that the addition of normal human gastric juice did not increase the potency of ye...

Background: Gastric lavage (GL) is one of the most commonly used decontamination method for cholinergic insecticide ingestion in developing countries despite lack of supporting evidence. This study was designed to evaluate the outcome of patients with cholinergic insecticide poisoning treated with GL in regards to timing and frequency of the procedure. Methods: In this prospective observational...
