Several novel animal models that represent the pathophysiological process of endolymphatic hydrops (ELH) of Meniere's disease (MD) have been developed. Animal models are important to identify and characterize the pathophysiology of ELH and to corroborate molecular and genetic findings in humans. This review of the current animal models will be useful in understanding the pathophysiology of and developing proper treatments for MD. Surgical animal models will be replaced by medication-induced animal models. Study models previously developed in guinea pigs will be developed in several smaller animals for ease of conducting molecular analysis. In this review, we provided updated resources including our previous studies regarding the current and desirable animal models for MD.

Tibet orbivirus (TIBOV) was identified as a novel orbivirus in 2014. Antibodies against TIBOV were detected in cattle, Asian buffalo, and goats, while all the sequenced TIBOV strains were isolated from mosquitos and Culicoides. The known TIBOV strains have been classified into four putative serotypes. In this study, two TIBOV strains isolated from Culicoides spp. in Shizong County of Yunnan Province, China, were fully sequenced. The phylogenetic analysis of outer capsid protein 2 (VP2) indicated that these two viral strains belong to two novel putative serotypes of TIBOV. The updated putative serotypes may help in an investigation of the distribution and virulence of TIBOV.

Three-dimensional (3D) culture system is useful technique for study of in vivo environment and it was used various experiments. This study was investigated to establish of embryo co-culture system and changes of PAs activity in 3D cultured endometrial cells of pigs. In results, growth of stromal cells into gel matrix were detected only with endometrial and myometrial cells. The most rapid growth of stromal cells were confirmed in $2.5{\times}10^5cells/ml$ and gel matrix containing 15% FBS. Expression of urokinase-PA (uPA) after treatment of hCG (0.5, 1.0, 1.5 and 2.0 IU/ml) were higher than without hCG, but, there are not significant difference among the treatment. On the other hand, expression of uPA after treatment of $IL-1{\beta}$ (0.1, 1, 10 and 100 ng/ml) were higher than without $IL-1{\beta}$, but, there are not significant difference. Expression of uPA after treatment of estrogen (0.2, 2, 20 and 200 ng/ml) were not difference, but PA activity was significantly decreased (p<0.05). Blastocyst was producing in PZM-3 medium containing FBS and endometrial cells were grown in PZM-3 medium. When embryos development with cultured endometrial cells, cleavage rates were not significant difference and blastocyst were not produced in co-culture with stromal cells and 3D culture system. 3D culture system had similar activity to in vivo tissue and these features are very useful for study of in vivo physiology. Nevertheless 3D culture system was not proper in embryo co-culture system. Therefore, we suggest that 3D culture system with embryo co-culture need continuous research.

Background: The physiologic characteristics of the cashmere trait and many of the differentially expressed genes relevant to hair cycling have been extensively studied, whereas genes involved in the prenatal development of hair follicles have been poorly investigated in cashmere goats. The aim of this study, therefore, was to quantify the time-course changes in the expressions of $TR{\alpha}$ and CRABPII genes in the fetal skin of Chinese cashmere goats at the multiple embryonic days (E70, E75, E80, E90, E100, E120 and E130) using real-time quantitative PCR (RT-qPCR). Results: RT-qPCR showed that $TR{\alpha}$ was expressed at E70 with relatively high level and then slightly decreased (E75, E80, and E90). The highest expression of $TR{\alpha}$ mRNA was revealed at E130 (P > 0.05). The expression pattern of CRABPII mRNA showed an 'up-down-up' trend, which revealed a significantly highest expression at E75 (P < 0.05) and was down-regulated during E80 to E120 (P < 0.05) and mildly increased at E130, subsequently. Conclusion: This study demonstrated that $TR{\alpha}$ and CRABPII genes expressed in different levels during prenatal development of cashmere. The present study will be helpful to provide the comprehensive understanding of $TR{\alpha}$ and CRABPII genes expressions during cashmere formation and lay the ground for further studies on their roles in regulation of cashmere growth in goats.

Objective: Pigs, an ideal biomedical model for human diseases, suffer from about 50% early embryonic and fetal death, a major cause of fertility loss worldwide. However, identifying the causal variant remains a huge challenge. This study aimed to detect single nucleotide polymorphisms (SNPs) and candidate genes for the number of mummified (NM) piglets using the imputed whole-genome sequence (WGS) and validate the potential candidate genes. Methods: The imputed WGS was introduced from genotyping-by-sequencing (GBS) using a multi-breed reference population. We performed genome-wide association studies (GWAS) for NM piglets at birth from a Landrace pig populatiGWAS peak located on SSC11: 0.10 to 7.11 Mbp (Top SNP, SSC11:1,889,658 bp; p = 9.98E-13) was identified in cyclin dependent kinase on. A total of 300 Landrace pigs were genotyped by GBS. The whole-genome variants were imputed, and 4,252,858 SNPs were obtained. Various molecular experiments were conducted to determine how the genes affected NM in pigs. Results: A strong GWAS peak located on SSC11: 0.10 to 7.11 Mbp (Top SNP, SSC11:1,889,658 bp; p = 9.98E-13) was identified in cyclin dependent kinase 8 (CDK8) gene, which plays a crucial role in embryonic retardation and lethality. Based on the molecular experiments, we found that Y-box binding protein 1 (YBX1) was a crucial transcription factor for CDK8, which mediated the effect of CDK8 in the proliferation of porcine ovarian granulosa cells via transforming growth factor beta/small mother against decapentaplegic signaling pathway, and, as a consequence, affected embryo quality, indicating that this pathway may be contributing to mummified fetal in pigs. Conclusion: A powerful imputation-based association study was performed to identify genes associated with NM in pigs. CDK8 was suggested as a functional gene for the proliferation of porcine ovarian granulosa cells, but further studies are required to determine causative mutations and the effect of loci on NM in pigs.

This study aimed to investigate the functional and physicochemical properties of yogurt, supplemented with germinated brown rice (GBR) containing γ-aminobutyric acid (GABA), during storage. GBR was produced by soaking brown rice at 30℃, and saccharified germinated brown rice (SGBR) was produced by treating brown rice with α- and β-amylase for 1 h, at 80℃ and 60℃, respectively. Yogurt was manufactured using a commercial starter (YC-X11, CHR. Hansen, Denmark) at 37℃ for 12 h. The fatty acids and GABA contents were analyzed using GC and HPLC, respectively. The fatty acids in the cereal samples consisted of oleic, linoleic, and palmitic acid. The portion of oleic acid was the highest, at 35.65% in GBR, and 32.16% in SGBR. During germination, the oleic acid content increased, whereas linolenic and palmitic acid contents from GBR tended to decrease. Although the portion of saturated fatty acids, such as stearic and myristic acid, decreased significantly (p<0.05), that of unsaturated fatty acids, such as oleic and linoleic acid, increased with an increase in supplementation of BR, GBR, or SGBR in the yogurt. The yogurt, supplemented with cereal samples, showed a tendency of an increase in the concentration of GABA with an increase in the supplementation of the cereal samples. However, yogurt supplemented with GBR showed the highest concentration of GABA, regardless of the supplementation of the cereal samples. These results indicated that yogurt supplemented with BR, GBR, or SGBR could be a promising dairy product.

Mammal microsomal glutathione transferase 1 (MGST1) can conjugate many toxic or carcinogenic substances and depress oxidative stress. In this study, Chicken MGST1 and its variants were cloned for the first time and were composed of 956 or 944 nucleotides. The 12 nt deletion in the exon 2 did not alter the GT-AG rule and the ORFs for the two MGST1 variants were the same, which both comprised 465 nucletides and encoded a peptide with 155 amino acids. It was found that the two different splice variants identified using RT-PCR expressed in all three organs investigated of Dwarf Brown Chicken, namely liver, spleen and shell gland. Moreover, the expression level of MGST1 mRNA in the liver of Dwarf Brown chickens was the highest (p<0.01), and there were no significant differences between the spleen and the shell gland. These results provide a base for studying the biological function of Chicken MGST1.

This study was conducted to investigate the development and gene expression in miniature pig nuclear transfer (mNT) embryos produced under different osmolarity culture conditions. Control group of mNT embryos was cultured in PZM-3 for 6 days. Treatment group of mNT embryos was cultured in modified PZM-3 with NaCl (mPZM-3, 320 mOsmol) for 2 days, and then cultured in PZM-3 (270 mOsmol) for 4 days. Blastocyst formation rate of the treatment group was significantly higher than the control and the apoptosis rate was significantly lower in treatment group. Bax-$\alpha$ and caspase-3 mRNA expression were significantly higher in the control than the treatment group. Also, the majority of imprinting genes were expressed aberrantly in in vitro produced mNT blastocysts compared to in vivo derived blastocyst H19 and Xist mRNA expression were significantly lower in the control than the treatment group or in vivo. IGF2 mRNA expression was significantly higher in the control than the treatment group or in vivo. IGF2r mRNA expression was significantly lower in the control. Methylation profiles of individual DNA strands in H19 upstream T-DMR sequences showed a similar methylation status between treatment group and in vivo. These results indicate that the modification of osmolarity in culture medium at early culture stage could provide more beneficial culture environments for mNT embryos.
