CONTEXT Mothers recall early-onset constipation in children attending gastroenterology clinics. OBJECTIVES To study the bowel habit of young children in the community to determine, first, whether early-onset constipation is confirmed in this setting and, second, the agreement between recalled and recorded bowel habit. METHODS Defecation data of 57 children aged 6.0-40.7 mo were obtained by ...
some lesions in the oral cavity and mostly on gingiva have predominant predilection towards females, and mostly occur in the first four decades of life when changes in sex hormone levels in blood are obvious. the present study aimed to investigate the presence and distribution of estrogen and progesterone receptors in peripheral giant cell granuloma (pgcg), pyogenic granuloma (pg) and periphera...
We previously showed that most VD and DJ gene combinations from newborn surface Ig- pre-B cells had one to three predominant junctions, all of which occurred at the sites of short sequence homologies between the two coding ends. Because the majority of sequences that are present in pre-B cells are in-frame, however, the possibility existed that the frequency of occurrence of predominant IgH jun...
Prolactin, an important polypeptide hormone, is secreted by specialized cells in the anterior pituitary gland and is predominantly under inhibitory influence of the hypothalamus. This hormone plays a crucial role in incubation signaling and egg production in avian. The aim of this study was to determine the polymorphisms at situation +2402 bp (PRL5) and a 24-bp nucleotide in/del at nucleot...
Background: Transfusion is the mainstay treatment of patients with thalassemia major and occasionally in thalassemia intermediate. Alloimmunization is an unwanted side effect of blood transfusion. The present study intended to determine the frequency of alloimmunization in patients with β- thalassemia major and thalassemia intermediate in Southwest Iran. Patients and Methods: This was a cross-...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
abstract background: economy, lack of welfare and social services, aids and civil war, and also substance abuse are predominant factors that attributes with street children. method: 576 street children of 10-19 years were evaluated. data were gathered by demographic and substance use check list. theses check lists were designed by the researchers and included some simple question about type...
BACKGROUND Short-term variability of RR interval and blood pressure occurs predominantly at low frequency (LF; approximately 0.1 Hz) and high frequency (approximately 0.25 Hz). The arterial baroreflex is thought to be the predominant determinant of the LF component of RR variability. Patients with severe congestive heart failure (CHF) have an attenuated or absent LF oscillation in RR variabilit...
