Background: In recent years, numerous regulators of gonadal function have been studied. Adenosine deaminase(ADA) is widely distributed throughout human tissues and may contribute in the regulation of menstrual cycle. The purpose of this study was to determine the plasma activities of total adenosine deaminase (ADAT), and its isoenzymes, ADA1 and ADA2, and ADA1/ADA2 ratio during the menses, foll...

Records at the USAF School of Aerospace Medicine, Division of Hyperbaric Medicine, were reviewed to determine the relationship between the incidence of altitude chamber decompression sickness (DCS) in females and menstrual history. The study period spans 11 years, from January 1978 to December 1988. There were 81 records suitable for study. A significant inverse linear correlation was noted bet...

Osteosarcoma (OS), also known as osteogenic sarcoma, is the most common primary malignancy of bone tumor in children and adolescents. However, its underlying molecular pathogenesis is still only vaguely understood. Recently, LIM mineralization protein-1 (LMP-1) was reported to be an essential positive regulator of osteoblast differentiation. In the present study, we found that the expression of...

Menstrual cycle is an endocrine function of the ovary, controlled by the hypothalamus-pituitary-gonadal axis. Variation in menstrual characters across different ages, socioeconomic status, place of residence, ethnic groups and so on suggests that the function of hypothalamus-pituitary-gonadal axis is influenced by some internal and external factors. The objectives of the present study are to un...

PARTICIPANTS One hundred and sixty-five women aged 17 to 19 years entering a local university in 1985. MAIN OUTCOME MEASURES The o...

Preterm birth is commonly defined as any birth before 37 weeks completed weeks of gestation. An estimated 15 million infants are born preterm globally, disproportionately affecting low and middle income countries (LMIC). It contributes directly to estimated one million neonatal deaths annually and is a significant contributor to childhood morbidity. However, in many clinical settings, the infor...

Background: Accurate determination of gestational age has become important for deciding the appropriate time termination pregnancy as well to monitor fetal growth during entire period pregnancy. Objective: The aim study was assess whether trans-cerebellar diameter, placental thickness or combining both them is more accurate assessment in 3rd trimester Patients and Methods: This a cross sectiona...

objective: the purpose of the present study was to examine the impact of menstrual cycle abnormalities among patients with polycystic ovary syndrome (pcos) on biochemical and anthropometric characteristics. materials and methods: we conducted a prospective observational study of patients 17-35 years of age with pcos that attended the department of gynecological endocrinology of our hospital. re...

Introduction: The Parikh’s formula is a calculation method that considers menstrual cycle duration in women who have an unusual interval of menstruation cycle. Since the accurate estimation of gestational age affects pregnancy outcomes, the present study aimed to compare the first trimester ultrasound and Parikh’s formula in determining the Expected Date of Delivery (EDD). Mate...

Background: Accurate estimation of gestational age (GA) is crucial for providing quality health care and need intervention in inadvertent conditions such as fetal growth restriction. Various parameters are used measuring GA, but none them valid 3rd trimester. Recently some studies focused on Fetal kidney length (FKL) measurement correct GA. This study the validation accuracy FKL.Objective: Esti...
