1. Rats fed on purified synthetic diets have a markedly lower cytochrome P-450 concentration and hydroxylating enzyme activity in liver microsomal fraction than rats fed on stock pellets. 2. When both groups are treated with phenobarbitone the difference is even greater, the purified diet allowing only 50% of the cytochrome P-450 concentrations of controls. 3. Addition of herring oil, linoleic ...

A fluorene-degrading strain named USTB-C was isolated from crude oil of production well in Dagang oil field, southeast of Tianjin, northeast China. The 16S rDNA sequence of USTB-C showed 100% similarity with that of Rhodococcus erythropolis PR4, it was belonged to Rhodococcus. The strain USTB-C could remove 55.8% of fluorene with an initial concentration of 100 mg L in 23 days without other sub...

objective: in patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. we designed a study for comparing the level of ox-ldl in diabetic patients with macro-albuminuria, micro-albuminuria, versus normo-albuminuric. materials and methods: one hundred and thirty five patients with type 2 diabet...

OBJECTIVES Protective effects of different extracts and essential oil from Pimpinella anisum L. seeds were examined against carbon tetrachloride (CCl4)-induced toxicity. The parameters such as serum transaminases, lactate dehydrogenase activity, hepatic glutathione content, liver lipid peroxidation and histopathological changes of liver were assessed as toxicity markers. In the in vitro model o...

Chinese yam with damaged outer skin can be easily oxidized and infected by spoilage fungi. To find preservatives in the storage of yam, Aspergillus niger 103 was isolated, identified, determined as dominant fungus according to Koch’s postulates. Then, strain used a model screen antifungal agents study mechanisms this study. We found that cinnamon essential oil best agent, minimum concentration ...

Background: Several lines of evidence suggest that oxidized LDL (Ox-LDL) scavenger receptors play a crucial role in the genesis and progression of diabetic atherosclerosis. This study aimed to elucidate the effect of vitamin D3 on gene expression of lectin-like oxidized LDL receptor-1 (LOX-1), scavenger receptor-A (SR-A), Cluster of Differentiation 36 (CD36), and Cluster of Differentiation 68 (...

In the first paper of this series (Lea, Parr & Carpenter, 1958) we reported the results of experiments on the effect of storage on the nutritive value of herring meal as a source of protein for chicks. Over a period of 24 months’ storage in air there was extensive oxidation of the lipids, but only a very small drop in ‘available’ lysine (lysine with a chemically reactive E-NH, group) and no sig...
