Background: It is known that Aflatoxin M1 (AFM1) contamination in milk can have carcinogenic, teratogenic, and mutagenic activities especially in liver for both children and adults. The main aim of this survey was to investigate the incidence of AFM1 in human and cow milk in Kashan, Iran. Methods: A total of 42 breast milk samples were collected from a central hospital in Kashan city during 3-...
background a fall in plasma concentration of energy status related hormones (leptin, insulin-like growth factor-1 (igf-1) and insulin) and body energy expenditure occurs in response to short term fasting. nevertheless, the relations of the fasting-induced changes in energy related hormones and metabolites with fasting energy expenditure (fee) under extended fasting condition have received littl...
Nowadays, demand for energy is one of the important and applicable issues in different countries. Energy demand is of great importance from the viewpoints devastating impact on the environment and in terms of economic costs. The household sector is the major consumer of energy study of the factors influencing the energy consumption can have beneficial results in terms of the application of appr...
Circle of Willis (CoW) plays a significant role in maintaining the blood supply for the brain. Specifically, when the stenosis occurs in the internal carotid artery (ICA), abnormal structures of CoW would decrease the compensatory capacity, leading to the local insufficiency of cerebral blood supply. The present paper built a series of lumped parameter models for CoW, and simulated the blood re...
The objective of this study was to determine the effects of feeding an increased amount of extruded flaxseed with high proportions of n-3 fatty acids (FA) to transition dairy cows on performance, energy balance, and FA composition in plasma, adipose tissue, and milk fat. Multiparous Israeli-Holstein dry cows (n = 44) at 256 d of pregnancy were assigned to 2 treatments: (1) control cows were fed...
Twenty-four mature, nonpregnant crossbred cows were used in a 42-d feeding study to evaluate the effects of dietary cation-anion difference (DCAD) on performance, dry matter intake, and pH of blood, urine, and uterine flushing. All cows were housed individually and provided free-choice access to bahiagrass hay and a corncottonseed meal supplement. Two treatments were randomly allocated to cows ...

BACKGROUND Addition of capsaicin (CAPS) to the diet has been shown to increase energy expenditure; therefore capsaicin is an interesting target for anti-obesity therapy. AIM We investigated the 24 h effects of CAPS on energy expenditure, substrate oxidation and blood pressure during 25% negative energy balance. METHODS Subjects underwent four 36 h sessions in a respiration chamber for measu...
Background and Aims: Immunohistochemical tests are one of the most important tests, which are under study to determine the prognosis of the cancers such as transitional cell carcinoma. By the time, flexible cystoscopy and urine cytology are the routine tests for following up the patients with transitional cell carcinoma, which are both operator dependent. On the other hand, cystoscopy is an inv...
