over the years, the use of plastics has complicated the problem of disposal of solid wastes. one strategy to reduce plastic waste is the use of biodegradable plastics. a group of these plastics are polyhydroxyalkanoates (phas). to date more than 250 different microorganisms are known to synthesize and accumulate pha. most pseu-domonas strains are able to accumulate mcl-pha. in previous studies,...

cow’s milk whey consists of many protein components and some of them are antigens to human and known to modulate immune responses. enzymatic hydrolysis is a useful method to modify proteins with allergenicity. the objective of this study was to identify whether the in vitro enzymatic hydrolysis could reduce the allergenicity of whey protein concentrates (wpc). in  this study, wpc were hydrolyze...

spirometry has been used as a common diagnostic test in asthma. most of the patients with a mild asthma have a fev1 within normal range. hence, other diagnostic methods are usually used. the aim of this study was to evaluate whether eosinophil cationic protein (ecp) could be an accurate diagnostic marker of mild asthma. in this study diagnosis of asthma was made according to internationally acc...

a key factor in spermatogenesis and disorders associated with this protein have been recognized to be related to male infertility. although it was suggested that this protein could have different functions during germ cell development, no studies have been conducted to uncover the mechanism of this potential function yet. here, we analyzed the expression pattern of rbmy protein isoforms in test...

background: methyl 2-benzimidazole carbamate (carbendazim) is a synthetic fungicide used against organisms that cause different types of plant diseases. it is widely used as a preservative in leather, paint, textile, fruit, and paper industry. it is also used as an anticancer drug in clinical medicine. methods: to evaluate the low dose toxicity of this compound in mammalian tissues, carbendazim...

in the development of neuroinflammatory diseases, alterations of the blood brain barrier (bbb) represent key events. the integrity of the bbb is partially maintained by endothelia cells (ecs), since they actively limit the transmigration of immune cells. however, the factors that cause endothelial cells to develop an immune cell-permissive phenotype are poorly understood. in general, it has bee...

background and objective: as apoptotic cell death is extremely involved in physiological development and many pathological situations such as cancer and neurodegenerative diseases, the understanding of its molecular machinery can be useful in designing new therapeutic strategies. the present study investigated the temporal expression of the proapoptotic protein bax in adult spinal motoneurons. ...

in this study, the energy reserves of prediapause and diapausing adult bugs were examined using colorimetric biochemical techniques to determine carbohydrates, lipids, glycogen, and protein content. to this end, 45-day-old bugs were obtained from three different sources: laboratory colony, cold-stored insects, or natural habitat. the results showed that prediapause males and females had signifi...

nutritive value of rumen epithelial scraping (rep) was assessed using in sacco and in vivo procedures. concentrates were so formulated that 0% (a), 35% (b), 70% (c), and 100% (d) of soybean meal (sbm), were replaced (weight for weight) with rep. in a completely randomized design, 16 west african dwarf (wad) goats were randomly allocated to the experimental diets to assess feed intake and digest...

we assessed the size and composition of the soil seed bank and above-ground vegetation in 52 relevés representing a range of habitats within an old- growth, temperate deciduous forest at hyrcanian region, northern iran. we identified 63 taxa in the seed bank, with an average density of 4202 seeds/spores per m2 by seedling emergence method. hypericum androsaemum, cardamine impatiens, and rub...
