Background: Lead (Pb) is one of the ubiquitous nonessential haevy metals in the environment. There are evidences, which show that lead toxicity has many undesired effects, including neurological, behavioral, immunological, renal, hepatic, male reproductive, dysfunctions. The objective of the present study was to investigate the effects of aqueous garlic extracts, vitamin E and N-Acetylcysteine ...

Investigations were carried out to establish the total biopotency of the natural vitamin E isomers in barley compared with that of DL-alpha-tocopheryl acetate. The chick was used as an experimental animal. Prevention of nutritional encephalomalacia (NE) and chick liver-storage and plasma-storage assays of vitamin E were the methods used in the study. The individual tocopherols and tocotrienols,...

the genus boswellia is one of the 17 genera belonging to burseraceae family. in this study resin of boswellia carteri birdwoodcollected or purchased from tehram herbal market as a food and non-food for chemical analysis. the essential oils of the resins of boswellia carteri birdwoodobtained by different methods of distillation (water distillation, steam distillation and hydro-steam distillation...

The presence of acetate exceeding 5 g/L is a major concern during E. coli fermentation due to its inhibitory effect on cell growth, thereby limiting high-density cell culture and recombinant protein production. Hence, engineered E. coli strains with enhanced acetate tolerance would be valuable for these bioprocesses. In this work, the acetate tolerance of E. coli was much improved by rewiring i...

This study aimed to identify the chemical composition (ash, cellulose, total chlorophylls, carotenoid, and essential oil (EO) content), antioxidant activity, mineral of lemon balm (Melissa officinalis L) obtained from Bulgaria. The EO was analyzed using gas chromatography-mass spectrometry (GC-MS). major constituents were caryophyllene oxide (33.99%), n-hexadecanoic acid (14.28%), α-citral (6.6...

First published January 4, 2006; doi:10.1152/jn.00842.2005. A severe and chronic deficiency of vitamin E ( -tocopherol) is associated with a characteristic neurological syndrome with typical “clinical,” neurop...

Excess acetate has long been an issue for the production of recombinant proteins in E. coli cells. Recently, improvements in acetate tolerance have been achieved through the use of genetic strategies and medium supplementation with certain amino acids and pyrimidines. The aim of our study was to evaluate an alternative to improve the acetate tolerance of E. coli BL21 (DE3), a popular strain use...

The ability of Escherichia coli to survive at low pH is strongly affected by environmental factors, such as composition of the growth medium and growth phase. Exposure to short-chain fatty acids, such as acetate, proprionate, and butyrate, at neutral or nearly neutral pH has also been shown to increase acid survival of E. coli and Salmonella enterica serovar Typhimurium. To investigate the basi...
