Eye movement intervention facilitates concurrent perception and memory processing.

A widely used psychotherapeutic treatment for post-traumatic stress disorder (PTSD) involves performing bilateral eye movement (EM) during trauma memory retrieval. However, how this treatment-described as eye movement desensitization and reprocessing (EMDR)-alleviates trauma-related symptoms is unclear. While conventional theories suggest that bilateral EM interferes with concurrently retrieved trauma memories by taxing the limited working memory resources, here, we propose that bilateral EM actually facilitates information processing.

Polymorphisms in luteinizing hormone receptor and hypothalamic gonadotropin-releasing hormone genes and their effects on sperm quality traits in Chinese Holstein bulls.

Genes of hypothalamic-pituitary-gonadal axis play a key role in male reproductive performance. This study evaluated the polymorphisms of luteinizing hormone receptor (LHR) and hypothalamic gonadotropin-releasing hormone (GnRH) genes and their effects on sperm quality traits including semen volume per ejaculate (VOL), sperm density (SD), fresh sperm motility (FSM), thawed sperm motility (TSM), acrosome integrity rate (AIR), and abnormal sperm rate (ASR) collected from 205 Chinese Hostein bulls. The study bulls consisted of 205 mature Chinese Holstein, 27 Simmental, 28 Charolais, and 14 German yellow cattle.

Conditioned medium from hypoxia-treated adipocytes renders muscle cells insulin resistant.

Adipose tissue hypoxia is an early phenotype in obesity, associated with macrophage infiltration and local inflammation. Here we test the hypothesis that adipocytes in culture respond to a hypoxic environment with the release of pro-inflammatory factors that stimulate macrophage migration and cause muscle insulin resistance. 3T3-L1 adipocytes cultured in a 1% O2 atmosphere responded with a classic hypoxia response by elevating protein expression of HIF-1α.

Polymorphisms in follicle stimulation hormone receptor, inhibin alpha, inhibin bata A, and prolactin genes, and their association with sperm quality in Chinese Holstein bulls.

Candidate genes follicle stimulation hormone receptor (FSHR), inhibin alpha (INHA), inhibin bata A (INHBA) and prolactin (PRL) were investigated for their association with sperm quality traits of semen volume per ejaculate (VOL), sperm concentration (SCON), motility (MOT), sperm motility in frozen semen (FMOT), acrosome integrity rate (AIR) and abnormal sperm rate (ASR) in a total of 123 normal mature Holstein bulls. Three reported single nucleotide polymorphisms (SNPs) of FSHR A-234500T (rs43676359), IHNA A192G (rs41257116), and IHNBA C7639T (rs43408735), and 3 novel SNPs (G7550A, C7661T, and T8370C) in exons 4 and 5 of bovine PRL gene (NC 007324) were analyzed. Analysis of variance revealed that FSHR A-234500T and INHBA C7639T polymorphisms significantly associated with VOL (P<0.

Effects of MboII and BspMI polymorphisms in the gonadotropin releasing hormone receptor (GnRHR) gene on sperm quality in Holstein bulls.

The hypothalamic gonadotropin-releasing hormone receptor (GnRHR) plays an essential physiological role in reproductive function, which triggers the synthesis and release of luteinizing hormone and follicle stimulating hormone in the pituitary. The objective of this study was to investigate the effects of polymorphisms of GnRHR gene on the quality of fresh and frozen semen in Holstein bulls. The PCR-RFLP method was applied to detect G286A and T340C transitions determining MboII and BspMI polymorphisms, respectively, in the exon I of bovine GnRHR gene and evaluated its associations with sperm quality traits in 131 Holstein bulls.

PKCε regulates contraction-stimulated GLUT4 traffic in skeletal muscle cells.

The signaling pathways that stimulate glucose uptake in response to muscle contraction are not well defined. Recently, we showed that carbachol, an acetylcholine analog, stimulates contraction of C2C12 myotube cultures and the rapid arrival of myc-epitope tagged GLUT4 glucose transporters at the cell surface. Here, we explore a role for protein kinase C (PKC) in regulating GLUT4 traffic.

An MspI polymorphism in the inhibin alpha gene and its associations with superovulation traits in Chinese Holstein cows.

To identify a predictor to forecast superovulation response on the basis of associations between superovulation performance and gene polymorphism, the PCR-RFLP method was applied to detect an A>G transition determining an MspI polymorphism at position 192 in the exon I of the bovine inhibin alpha (INHA) gene and evaluate its associations with superovulatory response in 118 Chinese Holstein cows treated for superovulation. Association analysis showed that cows with the GG genotype resulted in a significant increase in the number of ova (TNO) than AG and AA genotypes in the first (P=0.023), second (P=0.

Polymorphisms in the 5' upstream region of the FSH receptor gene, and their association with superovulation traits in Chinese Holstein cows.

To identify a predictor to forecast superovulation response on the basis of associations between superovulation performance and gene polymorphism, variation in the bovine follicle stimulating hormone receptor (FSHR) gene was investigated using PCR-single-strand conformational (PCR-SSCP) and DNA sequencing. One single nucleotide polymorphism (SNP) of G-278A located in the 5' upstream region of bovine FSHR gene was found in 118 Chinese Holstein cows treated for superovulation. Two SNPs of G-278A (GU253337) and A-320T (rs43676359) were analyzed.
