background: the lori-bakhtiari sheep breed is one of the most common native breed in the south-western parts of iran. the peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. objectives: this study was carried out to compare the serum concentrations of glucose, non-esterified f...
negative energy balance in pregnant ewes during last two month of gestation could result in fatal pregnancy toxemia and affects ewe and lamb health. the understanding of variations of energy related metabolites during this critical period may cast light upon to a better management of the situation. this study describes the variations of serum energy related biochemical metabolites at a period o...

Abstract In the present study, 180 Persian sturgeon fries at releasing weight with average weight of 1.8 ± 0.6 g were exposed to three different salinity levels including 0 (fresh water), 6 and 12 ppt in 96-hour and 10-day periods for measuring their gill metabolites by H-NMR based metabolomics. The results showed that changes in salinity caused changes in the metabolites involving in osmotic ...
IIn order to study the effects of increasing level of metabolizable energy and protein on feed intake, improve nutrient digestibility, performance and blood metabolites of Zell pregnant ewes at late gestation, 32 pregnant ewe (mean body weight 42.1 kg, 2.5 years-old, multiparous, 100 days of pregnancy) were used in completely randomized design with 4 treatments and 8 replicates. Treatments were...
Sunlight provides energy for photosynthesis and help in synthesis of carbohydrates required for the regulation of plant development. Plant scientists are studying the role of light in plant development, in the biogenesis of chloroplast and in signalling between chloroplast and nucleus. The simple carbohydrates produced during photosynthesis are used as energy by plant for biosynthesis of primar...
A strategy known as diapause (developmental arrest) has evolved in insects to increase their survival rate under harsh environmental conditions. Diapause causes a dramatic reduction in the metabolic rate and drastically extends lifespan. However, little is known about the mechanisms underlying the metabolic changes involved. Using gas chromatography-mass spectrometry, we compared the changes in...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
Introduction: The high prevalence of Alzheimerchr('39')s disease (AD) in todaychr('39')s societies indicates an urgent need for the development of methods that will help the early diagnosis of the disease. In this study, using proton nuclear magnetic resonance spectrometry (1H-NMR) metabolomics, identification of altered and distinct metabolites in serum of the rat model of AD was performed com...
Changes in the metabolite profiles of Lactobacillus sakei and its growth media, based on different culture times (0, 6, 12, and 24 h), were investigated using gas chromatography-mass spectrometry (MS) and liquid chromatography-MS with partial least squares discriminant analysis, in order to understand the growth characteristics of this organism. Cell and media samples of L. sakei were significa...
