One hundred and sixty seven Droughtmaster cows with calves were used in two experiments to evaluate the effect of early weaning and creep feeding on cow reproduction rates. Weaning of calves that weighed 48-92 kg instead of the conventional weaning weight of about 180 kg improved cow live weights and increased pregnancy rates by 48% at weaning. The early weaned calves were raised on Stylosanthe...

Introduction: Vitamin D deficiency is a reemerging public health issue and is thought to increase the risk of developing complications in pregnancy such as gestational hypertension. Objective: To determine if vitamin D deficiency plays a role in determining whether or not a mother will develop complications of pregnancy and delivery methods. Methods: A chart review of 165 charts was performed a...

Background In recent years, the Internet has become one of the most popular sources of health information for users, and pregnant women are no exception. This study aimed to investigate Internet usage among pregnant women for achieving health information on the finding of related studies. Materials and Methods This review study was conducted by searching databases such as IranMedex, Magiran, ...

Fertilization is triggered by changes in intracellular calcium concentration. In mammals, these transients in ooplasmic calcium concentration take the form of repetitive spikes, so called calcium oscillations (Ca-oscillations). These oscillations are important for relieve of meiotic arrest and to induce all the other events of oocyte activation. Although a surface mediated way of oocyte activat...

The paper presents the research results of varying severity experimental hypoxia influences on the content of cytokines (IGF-1, TNF-α, IL-1β, IL-4, IL-6, IFN-γ) in organs, tissues and cells (blood, liver, brain, uterus, adrenal glands, placenta, placental lymphocytes and macrophages) of pregnant rats. The results showed the increase of pro-inflammatory cytokines synthesis on the local and syste...

Inherited thrombophilia has been implicated as a possible cause of recurrent pregnancy loss. Although numerous studies are available in literature, thrombophilia rate seems to vary from study to another. The aim of our study was to determine the frequency of FII Prothrombin (G20210A), Factor V Leiden (G1691A), as well as methyl tetrahydrofolate reductase (MTHFR C677T) polymorphisms, protein C, ...

The genus Cyrtopodion is the most widely distributed of the four gekkonid genera of the angular-toed geckos that inhabit Pakistan and the contiguous Palearctic Region (Szczerbak & Golubev 1996), from the Indus Valley to the eastern borders of the Caspian Sea. Longitudinal rows of trihedral tubercles characteristically line the dorsum of these angular-toed geckos. They primarily inhabit arid bad...

the current study conducted a finite element (fe) and experimental investigation on tubular channel angular pressing as a noble severe plastic deformation technique for producing ultrafine grained and nanostructure tubular components. to examine the effects of the tcap process on the strain distribution and deformation behavior, fe simulations were employed. the fe results demonstrated that equ...
