The insulin-like growth factor 1 (IGF1) gene was studied as a candidate gene for high prolificacy in sheep. Polymorphisms of 5′ regulatory region and all four exons of IGF1 gene were detected in Small Tail Han (n = 277), Hu (n = 58), Texel (n = 48) and Dorset (n = 46) sheep by PCR-RFLP and PCR-SSCP analysis. A microsatellite polymorphic site and a(More)
Seven pairs of primers were designed to amplify 5′ promoter region, six exons and partial introns and to detect the polymorphisms of POU1F1 gene in five goat breeds with different prolificacy. The results showed that six mutations were identified in caprine POU1F1 gene including C256T in exon 3, C53T and T123G in intron 3, and G682T (A228S), T723G and C837T(More)
OBJECTIVE This study aimed to investigate whether or not hypoxia-inducible factor-1α (HIF-1α) gene variants are associated with the susceptibility and clinical characteristics of lumbar disc degeneration (LDD). METHODS We examined 320 patients with LDD and 447 gender- and age-matched control subjects. We also determined the HIF-1α gene variants, including(More)
Direct metal laser sintering is a technology that allows the fabrication of titanium (Ti) implants with a functional gradation of porosity and surface roughness according to three-dimensional (3D) computer data. The surface roughness of direct metal laser sintered titanium (DMLS-Ti) implants may provide abundant binding sites for bacteria. Bacterial(More)
BACKGROUND The head circumference growth reference charts for children in China are presently based on urban children. However, the references may not apply to rural children because of the differences between urban and rural areas, such as economy, culture, and dietary habits. Our objective was to provide a reliable continuous set of head circumference(More)
Goat RFRP gene was cloned and its mutations were detected in thirteen goat breeds whose reproductive seasonality and litter size were different. Then sequence characteristics were analyzed and association analyses were performed to reveal the relationships between mutations of RFRP gene and average daily sunshine duration, reproductive seasonality as well(More)
Thyroid stimulating hormone beta chain (TSHB) is mainly expressed in pituitary and its expression is closely related to photoperiodic control of seasonal reproduction in animals. In the present study, ten primer pairs have been used to clone the DNA sequence and to detect genetic mutations of goat TSHB gene. Two DNA fragments of goat TSHB gene were(More)
