The present study was conducted to investigate whether or not protein synthesis in tissues and in the whole body of laying hens would be affected by the position of an ovum passing along the oviduct during egg formation. Protein synthesis in tissues was measured in vivo by a primed-continuous infusion of [15N]methionine for 3 h, finishing at the time when an ovum would have stayed at one of the...

INTRODUCTION For many donor-conceiving heterosexual parents, the process of deciding whether and what to tell children about their genetic origin is challenging. We hypothesized that incomplete couple agreement about disclosure could be associated with parenting stress. The aim of the study was to investigate: (1) parenting stress levels among heterosexual parents of young children following ga...

spontaneous abortion (sab) is the most common complication of early pregnancy. numerous risk factors are associated with an increased risk of pregnancy loss such as: blighted ovum. the aim of this study was to determine the frequency of balanced chromosomal translocations in couples with a history of recurrent spontaneous abortions and ultrasound diagnosed blighted ovum. sixty eight couples wit...

Spontaneous abortion (SAb) is the most common complication of early pregnancy. Numerous risk factors are associated with an increased risk of pregnancy loss such as: Blighted ovum. The aim of this study was to determine the frequency of balanced chromosomal translocations in couples with a history of recurrent spontaneous abortions and ultrasound diagnosed blighted ovum. Sixty Eight couples wit...

background: knowledge of infertile couples about assisted reproductive technology is a fundamental parameter to optimize the infertility treatment and conduct it cooperatively. objective: to evaluate knowledge and attitude of infertile couples about assisted reproductive technology we designed a descriptive cross-sectional study. materials and methods: 400 infertile patients were investigated b...

clinical signs, para-clinical tests and gross lesion can be used for identification of parasite contamination. in most parasite contamination the clinical signs are not obvious. thus, para-clinical tests and gross lesion play important roles in identifying parasite disease as all organs of animals such as skin, eyes, kidneys, liver and digestive tube can be affected by the parasites. consequent...

Objective: Trying to diagnose clinically some suggested causes of unexplained infertility related to ovum picking, fertilization, embryo growth and implantation and to outline the most suitable management needed for these cases. Design: Prospective controlled diagnostic and management study. Setting: 50 fertile cases as control. Patients: Assessment of ovum picking was determined clinically in ...

Cervical pregnancy is defined as an implantation of a fertilized ovum in the cervical canal. It is a very rare and dangerous form of ectopic pregnancy. The incidence ranges from 1/2500 to 1/12,000 pregnancies, which accounts for approximately 0.15% of all ectopic pregnancies. Rapid crossing of the fertilized ovum through the endometrial cavity and the travel speed of the ovum could be the cause...

The two cultivated rice species, Oryza sativa and Oryza glaberrima, are morphologically alike but are reproductively isolated from each other by hybrid sterility. The hybrid is male sterile but partially female fertile. Backcross experiments were conducted to introduce an alien factor controlling hybrid sterility from O. glaberrima (W025) into O. sativa (T65wx) and examine the genetic basis. An...
