a study was carried out to evaluate the secondary sexual characteristics of four strains of cocks, comprising of two (2) exotics; bovan nera black (bnb) and isa brown (isb), one (1) improved local strain, shika brown (sb) and one (1) unimproved local strain, normal feathered cock (nfc). a total of 64 birds (16 for each strain) at 36, 38, 40 and 42 weeks were used for the study. the result indic...
objective: an experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens. methods: one hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. each replicate contains 15 chicks. the t...
This study was designed to determine the technical and economic efficiency levels of the commercial basal feeds enriched with 10%, 5% and 0% rates of LNA (LNA10, LNA5 and LNA0) on the growth performance of brown trout by analyzing the marginal factor cost (MFC) and the marginal revenue of physical product (MRPP). A total of 300 brown trout with an initial individual weight of 4±0.05 g were rand...

There are two different types of fat present in mammals: white adipose tissue, the primary site of energy storage, and brown adipose tissue, which is specializes in energy expenditure. Factors that specify the developmental fate and function of brown fat are poorly understood. Bone morphogenic proteins (BMPs) play an important role in adipogenesis. While BMP4 is capable of triggering commitment...

Brown adipose tissue (BAT) is specialized to burn lipids for heat generation as a natural defense against cold and obesity. Previous studies established microRNAs (miRNAs) as essential regulators of brown adipocyte differentiation, but whether miRNAs are required for the feature maintenance of mature brown adipocytes remains unknown. To address this question, we ablated Dgcr8, a key regulator o...
Leishmaniasis is a infectious disease with broad spectrum of clinical features from typical noduloulcerative lesion to atypical lesions. In this article, we presented 4 cases with atypical presentation of cutaneous leishmaniasis lesions (including eczematous, sporotrichoid and lichenoid) in an endemic area in Iran, Kerman. The first case was a 28- year- old man presented with a pruritic purplis...
