Comparative Analysis of miRNA Expression Profiles in Skeletal Muscle of Bian Chickens at Different Embryonic Ages.

MicroRNAs (miRNAs) are widely involved in the growth and development of skeletal muscle through the negative regulation of target genes. In order to screen out the differentially expressed miRNAs (DEMs) associated with skeletal muscle development of Bian chickens at different embryonic ages, we used the leg muscles of fast-growing and slow-growing Bian chickens at the 14th and 20th embryonic ages (F14, F20, S14 and S20) for RNA-seq. A total of 836 known miRNAs were identified, and 121 novel miRNAs were predicted.

[Distribution characteristics of Chinese medicine resources in Turpan Basin, Xinjiang].

Based on the results of the fourth national survey of traditional Chinese medicine resources in Turpan city, Xinjiang, this study counted the types of traditional Chinese medicine resources in Turpan Basin. The spatial distribution differences of traditional Chinese medicine resources in Turpan Basin of Xinjiang were analyzed by using grid technology, trend surface analysis, global spatial autocorrelation analysis, and local spatial autocorrelation analysis, so as to clarify the overall change trend and aggregation degree of traditional Chinese medicine resources in Turpan Basin in horizontal and vertical directions. The results showed the following: in the horizontal direction, the species richness of traditional Chinese medicine resources in the central part of Turpan Basin was high, and there were great differences in the species richness of traditional Chinese medicine resources in Turpan Basin under different grid sizes.

Leukotriene A Hydrolase Is a Candidate Predictive Biomarker for Successful Allergen Immunotherapy.

Background: Allergic rhinitis is a common disorder that affects 10% to 40% of the population worldwide. Allergen immunotherapy (AIT) represents the only therapy that has the potential to resolve clinical symptoms of allergic rhinitis. However, up to 30% of patients do not respond to AIT.

Indoor Allergen Levels and Household Distributions in Nine Cities Across China.

Objective: Chinese allergic subjects have high levels of sensitization to house dust mite (HDM) and other indoor allergens. This study quantifies common indoor allergen levels in Chinese households.

Methods: Dust samples were collected from nine cities.

[Automobile tyre colloidal particle induced allergic damage of respiratory system in traffic policemen and its allergenicity].

Objective: To explore the damage of respiratory system in the traffic policemen induced by automobile tyre colloidal particle and its allergenicity.

Methods: The respiratory system symptoms in 445 traffic policemen working outside their offices and 243 controls were investigated and their pulmonary ventilation function index such as FVC, FEV(1.0), MMF and V(50) were determined.
