Interferon is a protein secreted by eucaryotic cells following stimulation by viruses, bacteria, and many other immunogenes. Recent medical studies indicate that interferons have effective role in the treatment of virus infections, immunodeficiency and certain types of cancer such as hairy cell leukaemia (HCL). The aim of the present study is to apply yeast strain for secreting human IFNα2b fol...

proper conditions for producing crude beta-galactosidase from waste materials were de-termined. this enzyme is to be used in the production of lactose-hydrolyzed milk. whey permeate was used as a basic medium. twenty seven treatments were developed by 3 vary-ing factors of: yeast extract (1, 2, and 3 %), wheat steep liquor (1, 2, and 3 %), and whey powder (0.5, 1, and 1.5 %). crude enzyme extra...

Objective(s):Some evidence showed that calcitriol has an important role in regulating growth and differentiation of mesenchymal stem cells (MSCs). However, the interaction between mesenchymal stem cells and macrophage is not clear yet.  The current study was done to investigate the in vitro effects of calcitriol on the interactions between bone marrow-derived MSCs and rat macrophages. Material...

Yeast is widely used for industrial production of various types products, such as ethanol and enzymes. However, its fermentation efficiency strongly reduced by harmful environmental stresses. Specifically, stresses damage important cellular components, cell wall, membrane, proteins, etc. Then, these damages cause metabolic disorders or even death. In the past decades, there has been a portfolio...

The purpose of this work was to evaluate the total phenol content and antioxidant activity different types handcrafted beers (Ego, Alter, Fiat Lux, Triplo Malto, Ubi, Maior), as well starting materials (malts, hops, yeast), intermediate products, waste products (spent malts, in view their use innovative cosmetic formulations. Extractions from spent samples were taken water or 70° alcohol. (Foli...
