Background: There currently is a lack of knowledge about the long-term survival of patients with beta thalassemia (BT), particularly in regions with low incidence of the disease. The aim of the present study was to determine the survival rate of the patients with BT major and the factors associated with the survival time.Methods: This retrospective cohort study was performed in Hamadan province...
a camel research station was established in 1990 at the central desert land of iran named kavir-e-loot, to evaluate productivity performance of one humped camel. the data consisted of birth weights (bw), three (w3), six (w6), nine (w9) months and yearling (w12) body weight of animals and the pedigree was registered during a period of 14 years since 1991 to 2004. the body weight traits of birth,...
The rat Kid-1 gene codes for a 66-kDa protein with KRAB domains at the NH2 terminus and two Cys2His2-zinc finger clusters of four and nine zinc fingers at the COOH terminus. It was the first KRAB-zinc finger protein for which a transcriptional repressor activity was demonstrated. Subsequently, the KRAB-A domain was identified as a widespread transcriptional repressor motif. We now present a bio...
In prey species, vigilance is an important behavioural trait with regard to antipredator strategies. It has been studied intensely in animals. However, lile is known about vigilance in animal kids. In this study, I investigated the inuence of various environmental and social factors on Alpine ibex (Capra ibex) and Alpine chamois (Rupicapra rupicapra) kid vigilance behaviour. In the Gran Parad...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
The effect of growth rate from birth through 30 months of age on the reproductive performance of Polled Hereford heifers calving as 2-year-olds was examined. Heifers with high gains during the first winter as weanlings had higher breeding efficiency when bred as yearlings, had larger pelvic areas as 2-year-olds, gave birth to larger calves, had less calving difficulty at first parturition and h...
Purpose: the aim of this study is to analyze the factors contributing to the success of frozen- thawed embryo transfer (ET). Material and method: This retrospective, case-control study was carried out on 700 infertile couples treated with IVF and ICSI and had embryo freezing in Isfahan Fertility and Infertility Center, Iran, from the beginning of July 2000 to the end of June 2003. Results: fa...
Background: There is little information about the survival rate of pediatric peritoneal dialysis (PD) patients and its risk factors. Therefore, the aim of the present study was to assess survival rate and its risk factors in Iranian children undergoing PD. ...
Testosterone profiles and semen characteristics were determined using yearling and adult captive wild-strain Mallard (Anas platyrhynchos) drakes. Wild-strain Mallard hens were artificially inseminated by modifying a technique developed for domesticated poultry. In both adult and yearling drakes, there was a change in the concentration of circulating plasma testosterone during the reproductive s...
