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)
BACKGROUND The discovery of fetal DNA in maternal plasma has opened up an approach for noninvasive prenatal diagnosis. Despite the rapid expansion in clinical applications, the molecular characteristics of plasma DNA in pregnant women remain unclear. METHODS We investigated the size distribution of plasma DNA in 34 nonpregnant women and 31 pregnant women,(More)
In the present study, the exon 2 and 3′ end sequence of intron 1 of BoLA-DRB3 gene of 211 Beijing Holstein cows was amplified and a uniform fragment of 284 bp was obtained. The genetic polymorphism was investigated by PCR-RFLP using two restriction endonucleases HaeIII and BstYI. Seven genotypes were detected by digesting the PCR products with HaeIII. The(More)
Ring resonators with TiO 2 core confinement factors from 0.07 to 0.42 are fabricated and measured for thermal sensitivity achieving −2.9 pm/K thermal drift in the best case. Materials used are CMOS compatible (TiO 2 , SiO 2 and Si 3 N 4) on a Si substrate. The under discussed role of stress in thermo-optic behavior is clearly observed when contrasting(More)
Single nucleotide polymorphisms of 5′ regulatory region of follicle-stimulating hormone receptor (FSHR) gene were detected in two high prolificacy sheep breeds (Small Tail Han and Hu sheep) and two low prolificacy sheep breeds (Corriedale and Chinese Merino sheep) by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). The results(More)
We demonstrate real-time, longitudinal, label-free tracking of apoptotic and necrotic cells in living tissue using a multimodal microscope. The integrated imaging platform combines multi-photon microscopy (MPM, based on two-photon excitation fluorescence), optical coherence microscopy (OCM), and fluorescence lifetime imaging microscopy (FLIM).(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)
