Some barley mutants can synthesize neither anthocyanins nor proanthocyanidins in the seed coat, which is related to several genes in locus Ant13, but the exact model of action remains unknown. We used the cDNA microarray technology with barley transcription-deficient mutant (ant13-152) that does not synthesize proanthocyanidins as the tester, and its wild(More)
AIM Studies on synthesis and antibacterial activity of new heterocycles. METHODS The cyclocondensation of [(3-pyridyl)-1,3,4-oxadiazol-2-yl] thio acetic acid with various aroyl hydrazines in the presence of POCl3 and xylene gave the corresponding titled compounds, and the in vitro antibacterial activity was primarily evaluated by the method of cupplate(More)
Src family of protein tyrosine kinases (SFKs) play key roles in regulating signal transduction in cellular processes. However, hyper-activated SFKs lead to uncontrolled cell proliferation and cancers. Many SFKs inhibitors were designed and synthesized as anticancer agents in the past several years and great progress has been made. Herein, some predominant(More)
Metastatic temporal bone tumors are rare, and tend to be asymptomatic. The clinical symptoms consist of aural discharge, bleeding, hearing loss and facial nerve paresis. The most common origin of the metastasis is breast cancer, and other sites of the primary tumor include the thyroid gland, brain, lungs, prostate and blood. Clinical reports of hearing loss(More)
A system of virus-induced post-transcriptional gene silencing for studying rbcS gene function was established and optimized using tobacco rattle virus vector and Nicotiana benthamiana as experimental materiaes. The following analyses were conducted: phenotypic characterization of rbcS gene silenced plants, transcription levels of rbcS gene by RT-PCR;(More)
A series of N-(3-cyano-6-methyl-4-anilinoquinoline-7-yl) amide derivatives 13a-13n have been synthesized, their structures were confirmed with 1H NMR, EI-MS, IR and elemental analysis. Antitumor activities of all the synthesized compounds in vitro were tested with MTT. Compound 13j showed better than or equal antitumor activity on Bosutinib and EKB-569.

Pulmonary tuberculosis is a serious complication of anthracosilicosis and a promoting factor for death. It is very difficult to distinguish the advanced stage of atypical anthracosilicosis from anthracosilicosis associated with tuberculosis by the chest radiograph when the tubercule bacili is negative in sputum, but it is necessary for physician to treat(More)
