Determination of volatile flavor compounds in raw and treated duck meats of different body parts.

The compounds in volatile flavor substances in duck meats of three different body parts (breast, leg, and wing) were extracted by headspace solid-phase micro-extraction and determined by gas chromatography-mass spectrometry. A total of 16 main volatile compounds including 4 hydrocarbons, 4 alcohols, 2 acids, 3 aldehydes, and 3 others (N-containing, S-containing) were identified in raw duck meats from three different body parts. The hydrocarbon compounds account for more than 50% of all volatile substances in all three body parts.

Pharmacodynamic elucidation of glutamate & dopamine in ketamine-induced anaesthesia.

General anaesthetics are some of the most widely used and essential therapeutic agents. However, despite over a century of research, the molecular mechanisms of general anaesthesia in the central nervous system remain elusive.

Increase of SOX9 promotes hepatic ischemia/reperfusion (IR) injury by activating TGF-β1.

Ischemia/reperfusion (IR) injury causes damage in aerobically metabolizing organs or tissues, which is an essential injury mechanism in various clinical settings. SRY-related high mobility group-Box gene 9 (SOX9) is a transcription factor of the SRY family, modulating various cellular processes, including fibrosis formation and tumor growth. However, the effects of SOX9 on hepatic IR injury have not been explored.

Valproic acid, targets papillary thyroid cancer through inhibition of c-Met signalling pathway.

Tyrosine kinase receptors such as c-Met and its ligands are interesting therapeutic targets that have been reported to be involved in the progression of several types of cancers. Histone deacetylase inhibitor, valproic acid (VPA) is one such compound with promising anti-cancer properties. The current study was designed to evaluate the c-Met activity of VPA in thyroid carcinoma.

The allele and genotype frequency of nine X-STR loci among 120 unrelated individuals (55 female, 65 male) from Yugur ethnic group were analyzed using PCR and followed by polyacrylamide gel electrophoresis and silver staining. The numbers of alleles in the nine X-STR loci were 8, 6, 6, 5, 6, 7, 6, 4, and 6, respectively; the numbers of genotypes in the nine loci were 16, 14, 13, 6, 13, 20, 11, 6, and 12, respectively.

[Sequence polymorphism of mtDNA HVR Iand HVR II of Oroqen ethnic group in Inner Mongolia].

Venous blood samples from 50 unrelated Oroqen individuals living in Inner Mongolia were collected and their mtDNA HVR I and HVR II sequences were detected by using ABI PRISM377 sequencers. The number of polymorphic loci, haplotype, haplotype frequence, average nucleotide variability and other polymorphic parameters were calculated. Based on Oroqen mtDNA sequence data obtained in our experiments and published data, genetic distance between Oroqen ethnic group and other populations were computered by Nei's measure.

[The role of dopamine D3 receptor in the amphetamine-induced conditioned place preference in mice].

Objective: To study the role of dopamine D3 receptor involved in the amphetamine-induced conditioned place preference (CPP) in mice.

Methods: The CPP was observed in D3 receptor knock-out (D3RKO) mice and C57BL/6 wild-type control mice after administration of amphetamine. The data were analyzed with a two-way ANOVA using the SPSS 13.

[Genetic structure of STR in Naci ethnic group in China].

STR is a universal genetic marker that has changeable polymorphism and stable heredity in human genome. It is a specific DNA segment composed of 2-7 base pairs as its core sequence, and is formed through the repeated connection of the same one. Since it has the characteristics such as numerous allelic genes, highly heterozygosity and easy recognition and short PCR segment, it is employed as an ideal DNA marker in such practical fields as human genetics and forensic medicine.
