Cholinergic neurons acquire their neurotransmitter phenotype, in part, by expressing the cholinergic gene locus. Previous studies have indicated that the 5' flanking DNA of the locus contains both positive and negative regulatory elements important for expression in different subsets of cholinergic neurons in Drosophila and other animals. Approximately 300 bases of proximal 5' flanking DNA cont...

BACKGROUND Chemical activation is the most frequently used method for artificial oocyte activation (AOA), results in high fertilization rate. OBJECTIVE This prospective, randomized, unblinded, clinical study aimed to evaluate the efficiency of oocyte activation with calcium ionophore on fertilization and pregnancy rate after intracytoplasmic sperm injection (ICSI) in infertile men suffer from...

Background: The modified WHO partograph is an inexpensive but valuable tool that provides a continuous pictorial overview of progress of labor. It helps to detect the abnormal progress of labor. It guides the obstetrician to decide about the need for augmentation of labor and helps to recognize prolong labour before obstruction occurs. Objectives: The objectives were to study the course of norm...

AIM To evaluate the usefulness, diagnostic accuracy, and cost-effectiveness of transvaginal hydrolaparoscopy (THL) in infertile women with abnormal hysterosalpingogram (HSG) results without obvious pelvic pathology. MATERIAL AND METHODS THIRTY INFERTILE WOMEN (AGE: 20-40 years) who had tubal pathology in HSG were enrolled in the study. All patients underwent THL instead of standard laparoscop...

Crossbred (Bos taurus) yearling beef bulls were assessed for breeding soundness and physical traits prior to multi-sire natural mating at pasture. Bulls (n = 60) were assigned to six groups of nine or 10 bulls and two bull-groups were rotated on 14-day intervals during a 63-day mating season in each breeding herd (n = 3) of 191-196 cows. The remaining bulls (n = 14) were maintained under simila...

Semen characteristics were evaluated every 2 wk from 7 through 13 mo of age in 31 beef bulls representing six breed groups (Hereford, Angus, Hereford x Angus crossbreeds, Angus x Hereford crossbreds, Red Poll and Brown Swiss). Breeds differed in age at puberty, defined as the age at which an ejaculate was first obtained that contained a minimum of 50 x 10(6) total spermatozoa with at least 10% ...

PURPOSE To examine factors contributing to eye-hand coordination deficits in children with amblyopia and impaired stereovision. METHODS Participants were 55 anisometropic or strabismic children aged 5.0 to 9.25 years with different degrees of amblyopia and abnormal binocularity, along with 28 age-matched visually-normal controls. Pilot data were obtained from four additional patients studied ...
