The article presents a study which analyzes messenger RNA (mRNA) expression levels of five genes that are said to be related with egg production in the ovary tissue of Zi-goose during prelaying and laying periods including Esterase (EST)4, EST5, and EST6.

The article presents a study on the genome analysis of HUB2, a porcine reproductive and respiratory syndrome virus (PRRSV), which was obtained in HuBei Sheng, China. It states that the virus broke out in 2006 which presented symptoms of high fever. It mentions that the complementary deoxyribonucleic acid (cDNA) analysis of the HUB2 strain revealed a nucleotide identity from the North American strain VR-2332 and the European strain Lelystad.

The article presents a study on the highly pathogenic porcine reproductive and respiratory syndrome (PRRS) virus in China. It notes the large-scale outbreak of PRRS in the country in 2006, and mentions the formation of a research for the virus to fully understand its nature. The study found out that the pathogenic is similar to hemoglobin-1 (HB-1) and it has a unique molecular hallmark on its viral isolates with the continuous deletion of 30 amino acids in nonstructural protein two (Nsp2).

Abstract: LiV3O8 is a very promising cathode material for lithium secondary batteries. An EDTA-sol-gel method was proposed for the first time to obtain LiV3O8 at low temperature. LiAc·2H2O, NH4VO3 and EDTA were used as raw materials to prepare the precursor, and then the precursor was sintered to obtain the layered structure of LiV3O8. The effect of sintering temperature and duration on the quality of LiV3O8 was investigated. We also tested the electrochemical performances of LiV3O8 obtained through the method. The sample heated at 550 °C for 15 h has a single-phase layered structure and it has a first cycle discharge capacity of 251.7 mA h g−1 at the range of 1.8–3.6 V at 0.1 mA and an average capacity decay rate of 0.43% per cycle after 30 cycles.

Objective: This study aimed to evaluate the postoperative complications undergoing dental general anesthesia in children and analyze the prevalence and related factors., Methods: This prospective study involved 292 systematically healthy children (36 to 71 months old) who received extensive dental treatment under general anesthesia. Data about patients' histories, characteristics, dental and anesthesia procedure were collected. Parents or caregivers were interviewed face to face preoperation and 72 h postoperation. Data were analyzed using logistic regression., Results: Approximately 93.5% of the enrolled children reported one or more complications. The most prevalent complication was postoperative pain, followed by weariness, agitation, problem in eating, drowsiness, oral bleeding, cough, fever, etc. The length of operative time and femininity were the risks of the postoperative pain. Nutrition status was the factor probably in association with fever., Conclusions: The children receive longer operative time and girls show to be more susceptible to the postoperative pain. High nutrition status could be the protective factor of postoperative fever.

Getah virus (GETV) is a mosquito-borne alphavirus that is considered to be an emerging pathogen. To date, reverse transcription loop-mediated isothermal amplification (RT-LAMP) has not been used to detect GETV. Therefore, we describe a novel, fast, and sensitive LAMP method to detect GETV. Amplification of GETV RNA can be obtained within 50 min at 65°C. This RT-LAMP method was verified to be highly specific for GETV, with no cross detection of other viruses. The assay was 10 3 and 10 1 times more sensitive than RT-PCR and RT-qPCR, respectively, for the detection of GETV RNA. This novel RT-LAMP method provides a practical and economical alternative for detecting GETV in mosquitoes and serum samples that can be used even in the field.

We propose that locations of genes on chromosomes can contribute to the prediction of gene regulatory relationships. We constructed a time-based gene regulatory network of zebrafish cardiogenesis on the basis of a spatio-temporal neighborhood method. Through the network, specific regulatory pathways and order of gene expression during zebrafish cardiogenesis were obtained. By comparing the order with locations of these genes on chromosomes, we discovered that there exists a reversal phenomenon between the order and order of gene locations. The discovery provides an inherent rule to instruct exploration of gene regulatory relationships. Specifically, the discovery can help to predict if regulatory relationships between genes exist and contribute to evaluating the correctness of discovered gene regulatory relationships.

The title compound, [Mg(C(3)H(10)NO(6)P(2))(2)](n), synthesized by a hydro-thermal method, adopts a one-dimensional polymeric chain structure and is isotypic with the previously reported Cd complex based on the ligand N,N-dimethyl-amino-methane-1,1-diphospho-nic acid (H(4)L). The asymmetric unit contains one half Mg(2+) ion and one H(3)L(-) anion. The unique Mg(2+) ion lies on an inversion center and is octa-hedrally coordinated by O atoms from six phospho-nate groups of four different H(3)L(-) anions. Each H(3)L(-) anion, with one protonated N atom and two phospho-nate OH groups, serves as a tridentate ligand. Two of its six phospho-nate O atoms chelate to a Mg(2+) cation in a bidentate fashion, while a third O atom bridges to a neighbouring Mg(2+) ion. The inter-connection of Mg(2+) ions by the H(3)L(-)anions leads to the formation of a polymer chain along the a axis in which the adjacent Mg(2+) ions are doubly bridged by two equivalent H(3)L(-) anions. These discrete chains are further assembled into a three-dimensional supra-molecular network via O-H⋯O and N-H⋯O hydrogen bonds involving the non-coordin-ated phospho-nate O atoms and the protonated N atoms.
