objective: pulmonary air-leakage especially pneumothorax (ptx), is a severe complication in neonates. the aim of this study was to assess the predisposing factors and frequency of ptx among the low birth weight (lbw) premature infants, under mechanical ventilation. methods: this cross sectional study was performed in 121 lbw intubated premature infants at neonatal intensive care unit of a child...

Cytokinin oxidase (CKX) plays a crucial role in plant growth and development by reversibly inactivating cytokinin (CTK). Twenty-four primer pairs, designed from ESTs of the TaCKX genes family of common wheat, were used to identify their allelic variations associated with grain size, weight, and filling rate in 169 recombinant inbred lines (RIL) derived from Jing 411 × Hongmangchun 21. TaCKX6a02...

background & objectives: cryptorchidism is one of the most common congenital anomalies at birth. cryptorchidism is an abnormally positioned testis. the undescended testis can be located anywhere between the abdominal cavity and just outside the anatomical scrotum. this study was conducted to determine some etiologic factors in cryptorchidism. materials & methods: in an analytical cross-sectiona...

the objective of the present study was to determine chemical composition and fatty acid profile of common kilka ,clupeonella cultriventris caspia, in the caspian sea. the chemical analysis revealed that the protein and lipid content of common kilka were 15.05 and 6.5% of the fresh weight, and total mufa, pufa and sfa were found to be 37.00, 32.89 and 29.03% respectively. palmitic acid (16:0) am...

Data envelopment analysis which is a nonparametric technique for evaluating relative efficiency of the decision making units with multiple inputs and outputs, has been a very popular method among researchers. While this nonparametric technique is popular, it has some drawbacks such as lack of discrimination in efficient units and weights dispersion .The present study, which is a model based on ...

The common wheat relative species are important germplasm for wheat breeding. In the present study, novel allelic variants at Glu-B3 locus were cloned to provide gene resources for wheat quality improvement. Four Glu-B3-locus specific primer sets LB1F/LB1R, LB2F/LB2R, LB3F/LB3R, and LB4F/LB4R were employed to isolate novel allelic variants of GluB3-1, GluB3-2, GluB3-3, and GluB3-4 from seven co...
