background: margarine contain trans fatty acids as major sources of dietary free radicals, and oxidative stress. effect of oral administration of margarine on hepatic enzyme was investigated in wistar rats. methods: thirty six (36) adult wistar rats were uniformly divided into three groups of control , margarine 15% and 20%, twelve rats in each groups (6males & 6 females). margarine was added t...

The study was based on the evaluation of positive effect M2c macrophages liver tissue inflammation, pathological changes and damage in lipopolysaccharide/D-galactosamine induced acute hepatitis. Meanwhile, whether anti-inflammatory effects through Janus kinase/signal transducer activator transcription signaling pathway also investigated. Forty institute cancer research female mice same batch wi...

In this work, we examine the chromatographic purification of chiral amide N-(2-methyl-benzylidene)-phenylglycine (NMPA). Specifically, find that its adsorption behavior on an AY polysa...

The extremely halophilic archaeon Natrialba aegyptiaca secretes the L-homo type of poly-g-glutamate (PGA) as an extremolyte. We examined the enzymes involved in glutamate metabolism and verified the presence of L-glutamate dehydrogenases, L-aspartate aminotransferase, and L-glutamate synthase. However, neither glutamate racemase nor D-amino acid aminotransferase activity was detected, suggestin...

Em trabalhos anteriores em nosso laboratório, uma cepa de Pseudomonas aeruginosa demonstrou ter atividade enzimática na conversão de arilaminonitrilas em D-amino ácidos. Essa atividade enzimática aumentou por indução de modo a produzir D-fenilglicina enantiomericamente pura a partir de 2-fenil-2-aminoacetonitrila. No presente trabalho, as melhores condições para essa transformação são descritas...

Background and Objective: Tuberculosis (TB) remains an ongoing major public health problem in the world. In recent years, experimental evidenc suggests a link between TB and Vitamin (Vit) D. This study was conducted to determine serum Vit D, calcium (Ca), phosphorus (P), and parathormone (PTH) levels in untreated pulmonary TB (PTB) patients. Materials and Methods: In this case control study, 5...

Isolation of organelles from broken-cell suspensions of phototrophically grown Euglena gracilis Klebs was achieved by isopycnic centrifugation on sucrose gradients. 2. Equilibrium densities of 1.23g/cm3 for peroxisome-like particles, 1.22g/cm3 for mitochondria and 1.17g/cm3 for chloroplasts were recorded. 3. The enzymes glycollate dehydrogenase, glutamate-glyoxylate aminotransferase, serineglyo...

Metal pollutant adsorbents are an essential material platform for sustainable environmental remediation, but the typically disposable after sorption, which secondarily contaminates environment. We report on recyclable Cu(II) adsorbent of deprotonated poly-N-phenylglycine nanofibers (d-PPG NFs)-grafted reduced graphene oxide (rGO) sheets intercalated with Fe3O4 nanoparticles (NPs), synthesized v...

Background and Objective: Aging is a natural phenomenon which can cause changes in most organs and cells. Numerous mechanisms including oxidative stress and free radical generation is involved in the progression of the aging process. Pomegranate seed oil (PSO), has different therapeutic properties including anti-oxidant and anti-inflammatory effects. In this research, the effect of PSO against ...
