  • Objective: It is commonly accepted that adiponectin binds to its two receptors to regulate fatty acid metabolism in adipocytes. To better understand their functions in the regulation of intramuscular adipogenesis in goats, we cloned the three genes (adiponectin [AdipoQ], adiponectin receptor 1 [AdipoR1], and AdipoR2) encoding these proteins and detected their mRNA distribution in different tissues. We also determined the role of AdipoQ in the adipogenic differentiation of goat skeletal muscle satellite cells (SMSCs). Methods: SMSCs were isolated using 1 mg/mL Pronase E from the longissimus dorsi muscles of 3-day-old female Nanjiang brown goats. Adipogenic differentiation was induced in satellite cells by transferring the cells to Dulbecco's modified Eagle's medium supplemented with an isobutylmethylxanthine, dexamethasone and insulin cocktail. The pEGFP-N1-AD plasmid was transfected into SMSCs using Lipofectamine 2000. Expression of adiponectin in tissues and SMSCs was detected by quantitative polymerase chain reaction and immunocytochemical staining. Results: The three genes were predominantly expressed in adipose and skeletal muscle tissues. According to fluorescence and immunocytochemical analyses, adiponectin protein expression was only observed in the cytoplasm, suggesting that adiponectin is localized to the cytoplasm of goat SMSCs. In SMSCs overexpressing the AdipoQ gene, adiponectin promoted SMSC differentiation into adipocytes and significantly (p<0.05) up-regulated expression of AdipoR2, acetyl-CoA carboxylase, fatty-acid synthase, and sterol regulatory element-binding protein-1, though expression of CCAAT/enhancer-binding $protein-{\alpha}$, peroxisome proliferator-activated receptor ${\gamma}$, and AdipoR1 did not change significantly. Conclusion: Adiponectin induced SMSC differentiation into adipocytes, indicating that adiponectin may promote intramuscular adipogenesis in goat SMSC.

  • Objective: Ruminants are completely dependent on their microbiota for rumen fermentation, feed digestion, and consequently, their metabolism for productivity. This study aimed to evaluate the rumen bacteria of lactating yaks with different milk protein yields, using high-throughput sequencing technology, in order to understand the influence of these bacteria on milk production. Methods: Yaks with similar high milk protein yield (high milk yield and high milk protein content, HH; n = 12) and low milk protein yield (low milk yield and low milk protein content, LL; n = 12) were randomly selected from 57 mid-lactation yaks. Ruminal contents were collected using an oral stomach tube from the 24 yaks selected. High-throughput sequencing of bacterial 16S rRNA gene was used. Results: Ruminal ammonia N, total volatile fatty acids, acetate, propionate, and isobutyrate concentrations were found to be higher in HH than LL yaks. Community richness (Chao 1 index) and diversity indices (Shannon index) of rumen microbiota were higher in LL than HH yaks. Relative abundances of the Bacteroidetes and Tenericutes phyla in the rumen fluid were significantly increased in HH than LL yaks, but significantly decreased for Firmicutes. Relative abundances of the Succiniclasticum, Butyrivibrio 2, Prevotella 1, and Prevotellaceae UCG-001 genera in the rumen fluid of HH yaks was significantly increased, but significantly decreased for Christensenellaceae R-7 group and Coprococcus 1. Principal coordinates analysis on unweighted UniFrac distances revealed that the bacterial community structure of rumen differed between yaks with high and low milk protein yields. Furthermore, rumen microbiota were functionally enriched in relation to transporters, ABC transporters, ribosome, and urine metabolism, and also significantly altered in HH and LL yaks. Conclusion: We observed significant differences in the composition, diversity, fermentation product concentrations, and function of ruminal microorganisms between yaks with high and low milk protein yields, suggesting the potential influence of rumen microbiota on milk protein yield in yaks. A deeper understanding of this process may allow future modulation of the rumen microbiome for improved agricultural yield through bacterial community design.

  • From the studies on a few specific chapters of Tibetan Medical Painting, following conclusions were obtained. 1. The doctors of Tibet had to be not only academically and morally perfect, but he must show and have respect for his religion and his religous leaders and Gods. 2 The most main causes for all the disease that Tibetan Medicine resumed were hatred, delusion and ignorance of human mind which can make the physiological bile, wind, and phlegm to turn into pathological ones. 3. There is the classification of primary cause, which would be the human mind mentioned above, and the secondary cause which include dietary, behavior, seasonal problems, etc. 4. The Tibetans thought the digestive power is very important in the improvement or degravation of the disease. 5. More chapters were held for explaining the disease of fever, its clssification, stages, and cures which can indirectly show that the Tibetans might have thought it was very serious and could be very harmful. 6. The treatments for all the kinds of disease not only include medication and external therapy but also dietary and behavior regulations.

  • Tibetans are one of the ethnic Chinese minorities, and this research examined the characteristics and features of their traditional costumes by investigating their historical, geographical and cultural background. This research also examined the cultural elements according to their characteristics based on Tibet's nature, religion, arts culture such as the Jang-po, Chin-sam, Kam-kjun and belts, which are used to fix the costumes. Based on such studies the traditional Tibetan costumes were set as a motif and were expressed appropriately into a contemporary style. By studying the composition of its costumes and its costume culture, the characteristics of the Tibetan costumes could be classified into four features. First, the 'variability of form' expresses a new type depending on how it is worn. Second, the 'color contrast' shows a strong visual contrast. Third, the 'difference of materials' combines different materials into one. Fourth, the 'symbolic meaning' grants meaning to the wearer. As a result of this study, by using the characteristics of the Tibetan nature culture, religion culture and art culture as a basis, two suits of clothes for each characteristics and six suits of clothes were produced as a fashion design product.

  • Objective : The aim of this study is to review the historical development and current situation of Mongolian traditional medicine. Method : Systematic literature review for books, journals, governments statistics, reports on mongolian traditional medicine was carried out. Results : The theory of Mongolian traditional medicine is influenced by the philosophy and medical theories of the ancient orient such as India, Tibet and China-theories of hot and cold, principle of yin and yang and five elements. There are very unique treatments like brain tram concussion, fermented horse milk treatment as well as moxibustion, acupuncture, and blood letting. It appears that they are very closed to nomadic life. Training program of each institutes need to be standardized. Mongolian traditional medicine had been almost destroyed by the influence of communist idea from 1930s until the end of the 1980s. Since 1990, Mongolian government put much emphasis on the development of traditional medicine. And now about 3.7% of total beds is traditional medicine one and that there are six TM schools and the total number of traditional medicine in 2012 is 1696. However, there are still the lack of manpower, facilities, standardized training program and scientific research for traditional medicine. Conclusion : Mongolian traditional medicine has been developed over centuries in response to Mongolia's unique geographical and climate conditions and the lifestyles of its people and that made contribution to the health of mongolian people. However, it needs to be strengthened because there are poor infrastructure and training program.

  • Soil moisture, through its dominance in the exchange of energy and moisture between the land and atmosphere, plays a crucial role in influencing atmospheric circulation. To identify the crucial role, it is a common agreement that knowledge of land surface processes and development of remote sensing techniques are of great important scientific issues. This research uses TRMM satellite C band (10.65 GHz) data to retrieve soil moisture on the Tibetan Plateau in Mainland China. Two retrieval schemes that are implemented include the t-(J) model and the R model. The latter one is developed based on a land surface process and radiobrightness (R) model for bare soil and vegetated terrain. Compared with the in situ ground measurements, the soil moisture retrieved from the R model and the t-(J) model with vegetation information obviously appear more accurate than that derived from bare soil model. Retrieved soil moisture contents from the two inversion models, R model and t-(J) model, have a similar trend, but the former appears to be superior in terms of correlation coefficient and bias compared with in situ data. In the future, we will apply the R model with the TRMM 10.65 GHz brightness temperature to monitor long-term soil moisture variation over Tibet Plateau.

  • NCEP reanalysis data were analyzed in order to provide distribution of global wind resource and wind speed in the surface layer for the years 2000-2009. Wind speed at 10 m above ground level (AGL) was converted to wind speed at 80 m above the ground level using the power law. The global average 80 m wind speed shows a maximum value of $13ms^{-1}$ at the storm track region. High wind speed over the land exists in Tibet, Mongolia, Central North America, South Africa, Australia, and Argentina. Wind speed over the ocean increased with a large value in the South China Sea, Southeast Asia, East Sea of the Korea. Sea surface wind in Western Europe and Scandinavia are suitable for wind farm with a value of $7-8ms^{-1}$. Areas with great potential for wind farm are also found in Eastern and Western coastal region of North America. Sea surface wind in Southern Hemisphere shows larger values in the high latitude of South America, South Africa and Australia. The distribution of low-resolution reanalysis data represents general potential areas for wind power and can be used to provide information for high-resolution wind resource mapping.

  • A bacterial strain, 13-$25^T$ with xylanolytic activity isolated from a single soil sample, was characterized with respect to its phenetic and phylogenetic characteristics. The cells of the isolate are Gram-staining variable rods, but spore formation was not observed. This strain is catalase- and oxidase-positive, and able to degrade starch and xylan. The predominant fatty acids are anteiso-$C_{15:0}$, $C_{16:0}$, and iso-$C_{16:0}$. The major respiratory quinone is menaquinone 7(MK-7), with a polar lipid profile consistent with the genus Cohnella. The DNA G+C content is 54.3 mol%. The 168 rRNA gene sequence analysis indicates that this organism belongs to the genus Cohnella, with Cohnella panacarvi as the closest phylogenetic neighbor. Low levels of 168 rRNA gene sequence similarity (<97.0%) with respect to other taxa with published names and the identification of distinctive phenetic features in the isolate indicate that the strain 13-$25^T$ represents a novel species of the genus Cohnella, for which the name Cohnella damensis sp. novo is proposed. The type strain is 13-$25^T$ (=CCTCC AB $208103^T$=KCTC $13422^T$).

  • The engineering background of this article is an ancient wooden building with extremely high historic and cultural values in Tibet. A full understanding of the dynamic behaviour of this historic building under in-service environments is the basis to assess the condition of the structure, especially its responses to earthquake, environmental and operational loading. A dynamic monitoring system has been installed in the building for over one year and the large amounts of high quality data have been obtained. The paper aims at studying the dynamic behaviour of the wooden building in seismic and operational conditions using the field monitoring data. Specifically the effects of earthquake and crowd loading on the structure's dynamic response are investigated. The monitoring data are decomposed into principal components using the Singular Spectrum Analysis (SSA) technique. The relationship between the average acceleration amplitude and frequencies of the principle components and operational conditions has been discussed. One main contribution is to understand the health condition of complex ancient building based on large databases collected on the field.
