Leptin and leptin receptor gene polymorphisms are correlated with production performance in the Arctic fox
Authors: M. Zhang and X.J. Bai
The polymerase chain reaction-single-strand conformation polymorphism technique was employed to measure mononucleotide diversity in the coding region of the leptin and leptin receptor genes in the Arctic fox. The relationships between specific genetic mutations and reproductive performance in Arctic foxes were determined to improve breeding strategies. We.. Read More»

Association of IL-4 promoter polymorphisms with asthma: a meta-analysis
Authors: L. Tang, H.G. Lin and B.F. Chen
This study aimed to more precisely assess the correlation between interleukin-4 (IL-4) promoter polymorphisms and the susceptibility risk of asthma. We conducted association studies on IL-4 promoter C-33T, C-589T, and G-1098T polymorphisms with asthma using data obtained from MEDLINE up to September 2011. Results showed that t.. Read More»

Variation of plasma levels of endothelin,calcitonin gene-related peptide, nitric oxide,and malondialdehyde in acute myocardial ischemia reperfusion injury in a rabbit model
Authors: Y.B. Zhao, Y.Z. Wang, Y.H. Yue, W.C. Zhao and G.X. Feng
We examined the variation in plasma levels of endothelin (ET), calcitonin gene-related peptide (CGRP), nitric oxide (NO), and malondialdehyde (MDA), as well as superoxide dismutase (SOD) activity, in acute myocardial ischemia reperfusion injury in a rabbit model. Seventy rabbits were randomly assigned into 3 groups. Openchest surgery (OCS) was performed f.. Read More»

Occurrence of natural triploidy in Rhamdia quelen (Siluriformes, Heptapteridae)
Authors: J.R. Tsuda, V.P.O. de Moraes, L. Giuliano-Caetano and A.L. Dias
Five specimens of Rhamdia quelen collected from the Lindóia Stream, PR, Brazil, were cytogenetically analyzed. The diploid chromosome number found was 58, including 30 metacentric, 16 submetacentric, 10 subtelocentric, and 2 acrocentric chromosomes. Supernumerary or B chromosomes, frequently observed in this fish group,.. Read More»

Ammonia concentration and relative humidity in poultry houses affect the immune response of broilers
Authors: F.X. Wei, X.F. Hu, B. Xu, M.H. Zhang, S.Y. Li, Q.Y. Sun and P. Lin
To investigate the effect of ammonia (NH3) and humidity on the immune response of broilers, broilers were exposed to 30 or 70 mg/kg atmospheric NH3 for 21 days. Additionally, birds were exposed to 35, 60, and 85% relative humidity (RH). The relative weights of lymphoid organs, serum total protein, serum globulin, serum albumin, serum lysozyme, proliferati..

Cytogenetic evidence for de novo synthesis of rRNA and involvement of nucleolar material in the organization of cell structures during spermiogenesis of Chariesterus armatus (Heteroptera, Coreidae)
Authors: R.L.M. Arakaki, H.V. Souza, M.M.U. Castanhole, H.E.M.C. Bicudo and M.M. Itoyama
The nucleolar material of Chariesterus armatus was analyzed during spermiogenesis in cell preparations impregnated with silver nitrate. Nucleolar corpuscles were observed in spermatids at the beginning of the process, showing that this organoid is also maintained after meiosis. In addition, nucleoli were seen in the round sper..

Isolation, proliferation, and induction of Bama mini-pig spermatogonial stem cells in vitro
Authors: H.M. Zhao, H. Yang, F.H. Luo, M.X. Li, S. Zhang, X.G. Yang, Y.Q. Lu, S.S. Lu, Y.J. Wu and K.H. Lu
Spermatogonial stem cells (SSCs), the unique seed cells of testes, can undergo meiosis and form spermatozoa, thus transmitting genetic information to offspring. Research concerning these cells explores the mechanism underlying spermatogenesis, making possible the induction of their differentiation into spermatozoa in vitro. SSCs have therefore attracted m..

Association analysis between carcass weight and meat quality of Bamei pigs
Authors: J.P. Zhou, G.F. Wu, A.Q. Xiang, L. Wang, S.D. Sun, C. Yang and F.F. Xu
A total of 48 crossbred Bamei pig carcasses were divided into three groups (A, 60-69 kg; B, 70-79 kg; and C, 80-90 kg) to investigate the influence of carcass weight on meat quality. The intramuscular fat content of the three groups increased from 2.20% (Group A) to 4.14% (Group C). Group B had higher drip loss (6.83%, P < 0.05) than the other two grou.. Read More»

Targeted gene therapy and in vivo bioluminescent imaging for monitoring postsurgical recurrence and metastasis in mouse models of liver cancer
Authors: Q. He, C.L. Yao, L. Li, Z. Xin, Z.K. Jing and L.X. Li
We investigated the effects of combined targeted gene therapy on recurrence and metastasis after liver cancer resection in nude mice. Twenty BALB/C mice were randomly divided into control and treatment groups with 10 mice in each group and a male/female ratio of 1:1. Luciferase gene-labeled human primary hepatic carcinoma cell line MHCC97-H was then used .. Read More»
