three hundred twin births from a hospital in tehran, iran have been analyzed for seasonal variation at birth and physical measurements. the results show that the highest twinning rates for mm (5.61), ff (7.73) and mf (5.36) were seen in april, january and september, respectively. the four physical measurements at birth showed non-significant differences among the male and female twins, but mm a...

The aim of this study was to determine the physical growth of healthy full-term neonates during the first month of life. for this porpuse 789 Kermanian healthy full-term singeltone infants were prospectively studied at birth,on the 10th and the 30th day of life for increase in weight(WT),crown heel lenght (CHL),head circumference(HC),chest circumference(CC), and mid arm circumference(MAC).at bi...

A total body plethysmograph is descirbed which was used to study thoracic gas volume (TGV) in infants and young children from birth to 2 1/2 years, and was suitable for use even in very sick babies. Normal TGV values were obtained in 42 studies of 35 healthy infants and young children, and 16 children with abnormal lung volume are described. TGV correlated well with length, weight, chest circum...

Recently, the number of health-related car accidents in Japan has been increasing. Most health conditions leading to traffic are detectable by analyzing fluctuation blood pressure. In addition, cardiopulmonary arrest is an important condition that linked and should be studied along with respiration. Therefore, this study proposes a noncontact measurement system for cardiac dynamics respiration ...

The delta-like 2 homolog (DLK2) modulates adipogenesis, hematopoiesis, osteogenesis, and other cell-differentiation processes. In the present study, we detected potential polymorphisms in the DLK2 gene in 604 individuals of Qinchuan cattle by using PCR-RFLP and DNA-sequencing methods. Herein, we identified five novel single-nucleotide polymorphisms (SNPs) (g.888G>A, g.910A>G, g.995G>A, g.4321A>...

BACKGROUND The World Health Organisation has recommended the use of anthropometric measurements as birth weight surrogates. However, it has been found that cut-off points for these anthropometric measurements vary across nations and ethnic groups. OBJECTIVES To determine the predictive values of chest circumference (CC), occipito-frontal circumference (OFC) and their combinations for low birt...

Case 3. He was born in April 1964 after a normal 40 weeks' gestation and spontaneous delivery. When 4 months old it was noticed that growth and development were retarded, and that chest deformities and contractures of the lower extrenities were appearing. The clinical picture was identical to that of Case 2 (see Table and Fig. 2). At 4j years he was admitted to hospital with pneumonia; at that ...
