Melanocortin- 4 receptor (MC4R) and agouti- related peptide (AgRP) are involved in energy homeostasis in rats. According to MC4R and AgRP effects on luteinizing hormone (LH) secretion, they may influence the estrous cycle of rats. Therefore, the aim of this study was to investigate the expression of MC4R and AgRP mRNAs at different stages of estrous cycle in the rat’s hypothalamus. The estrous ...

no published information are available on the reproductive indices of local abadeh does reared innorthern fars province, southern iran. this study was conducted to determine the duration of the breedingseason, and the length and duration of the oestrous cycle. twenty single parity 2-year-old does from abadeh(weighing 19–26 kg) were purchased and transferred to the school of veterinary medicine ...

nowadays, economic load dispatch between generation units with least cost involved is one of the most important issues in utilizing power systems. in this paper, a new method i.e. water cycle algorithm (wca) which is similar to other intelligent algorithm and is based on swarm, is employed in order to solve the economic load dispatch problem between power plants. in order to investigate the eff...

life cycle assessment (lca) is one of the decision support systems which can be considered for assessing the different approaches of waste management. however, it only considers environmental effects and ignores other decision making options such as economic and social effects of solid waste management. in this research, we consider a combination of three decision making options including en...

cellular and molecular pathways link thrombosis and innate immune system during sepsis. extrinsic pathway activation of protease thrombin through fviia and tissue factor (tf) in sepsis help activate its endothelial cell (ec) membrane protease activated receptor 1 (par-1). thrombin adjusts the ec cycle through activation of g proteins (g12/13), and later through rho gefs (guanine nucleotide exch...

introdouction: lichen planus is a chronic, relatively common, dermal mucosa disease. the world health organization (who) has introduced lichen planus as a premalignant condition. ki-67 is a protein that can be detected in all active phases of the cell cycle, especially in the g2 and m phases. considering the major role of ki-67 in the regulation of the cell cycle and the fact that it is one of ...

introduction: studying the hydrological cycle, especially in large scales such as water catchments, is difficult and complicated despite the fact that the numbers of hydrological components are limited. this complexity rises from complex interactions between hydrological components and environment. recognition, determination and modeling of all interactive processes are needed to address this i...

matroids are important combinatorial structures and connect close-lywith graphs. matroids and graphs were all generalized to fuzzysetting respectively. this paper tries to study  connections betweenfuzzy matroids and fuzzy graphs. for a given fuzzy graph, we firstinduce a sequence of matroids  from a sequence of crisp graph, i.e.,cuts of the fuzzy graph. a fuzzy matroid, named graph fuzzy matro...

effect of five soybean varieties (sahar, jk, bp, williams and l17) on life cycle and fecundity of the beet armyworm, spodoptera exigua (hã¼bner) was evaluated at temperature of 25 â± 1â°c, 60 â± 5% r.h. and a photoperiod of 16: 8 (l: d) h. the preimaginal development period of males and females was longest on l17 (30.17 â± 0.28 and 29.63 â± 0.23 days) and shortest on bp and sahar. the adult lon...
