Cells of a high CO(2)-requiring mutant (E(1)) and wild type of Synechococcus PCC7942 were incubated with COS in the light, then suspended in COS-free medium and their CO(2) exchange was measured using an open gas-analysis system under the conditions where photosynthetic CO(2) fixation is inhibited. When the suspension of cells untreated with COS was illuminated, the rate of CO(2) uptake was hig...

BACKGROUND Obesity is a health hazard which is closely associated with various complications including insulin resistance, hypertension, dyslipidemia, atherosclerosis, type 2 diabetes and cancer. In spite of numerous preclinical and clinical interventions, the prevalence of obesity and its related disorders are on the rise demanding an urgent need for exploring novel therapeutic agents that can...

Butyrate, a short-chain fatty acid fiber fermentation product, induces colonocyte apoptosis in part via a Fas-mediated (extrinsic) pathway. In previous studies, we demonstrated that docosahexaenoic acid (DHA, 22:6(Delta4,7,10,13,16,19)) enhances the effect of butyrate by increasing mitochondrial lipid oxidation and mitochondrial Ca(2+)-dependent apoptosis in the colon. In this study, we further...

Methods to enhance crude oil biodegradation by mixed bacterial cultures, for example, (bio)surfactant addition, are complicated by the diversity of microbial populations within a given culture. The physical and metabolic interactions between Rhodococcus sp. strain F9-D79 and Pseudomonas sp. strain JA5-B45 were examined during growth on Bow River crude oil. The effects of a nonionic chemical sur...

fertilizers usually enhance potassium (k) content and other naturally occurring radioactive materials in agricultural fields that eventually enter the human food chain through plants. in this study, pot-grown rice plants planted in soil that is relatively high in natural radioactive content was used to estimate the individual influence of fertilizer applications on the uptake of 226ra, 232th, a...

OBJECTIVE This study examined the in vivo differentiation of mesenchymal stem cells (MSCs) into insulin producing cells (IPCs) on electrospun poly-L-lactide acid (PLLA) scaffolds coated with Matricaria chammomila L. (chamomile) oil. MATERIALS AND METHODS In this interventional, experimental study adipose MSCs (AMSCs) were isolated from 12 adult male New Zealand white rabbits and characterized...

Gerbera(Gerbera jamesonii) from the family of Asteraceae is regarded as one of the best cut flowers in the world. Despite of the publicity of Gerbera’s cut flowers, they have a short postharvest life. The objective of the present study was to study the replacement feasibility and the comparison of thymol (isolated from zataria), and essential oils of peppermint and rosemary (200, 400 and 600 mg...

In this work, biodegradable macroporous stimuli-responsive polypeptide hydrogels based on l-glutamic acid (Glu) and its copolymers with equimolar amounts of l-phenylalanine (Phe) or l-lysine (Lys) were prepared by deprotection the corresponding organogels under acidic conditions. The synthesized ring-opening polymerization N-carboxyanhydride (NCA) derivatives ?-amino acids in oil-in-oil high-in...
