By binding to nicotinic acetylcholine receptors (nAChRs), nicotine induces the proliferation and apoptosis of non-small cell lung cancer (NSCLC). Previous studies have indicated that α5-nAChR is highly associated with lung cancer risk and nicotine dependence. However, the mechanisms through which α5-nAChRs may influence lung carcinogenesis are far from(More)
An isocratic high-performance liquid chromatographic method is developed for the determination of phospholipids in biological samples using a muPorasil silica column and a mobile phase of acetonitrile-methanol-85% phosphoric acid (90:3:1, v/v/v) at a flow rate of 0.80 mL/min. The effluent is monitored by a UV detector at 203 nm. With the method reported in(More)
Hypertrophic scarring is abnormal proliferation of dermal fibroblasts and excessive deposition of extracellular matrix. To date, despite many studies, treatments have not been satisfactory. Genistein, a potent, specific inhibitor of tyrosine protein kinases (TPKs), has been proved to inhibit many kinds of tumour and some fibrotic diseases. The purpose of(More)
A dwarf mutant from Brassica napus, namely NDF-1, which was derived from a high doubled haploid (DH) line ‘3529’(Brassica napus L.) of which seeds were jointly treated with chemical inducers and fast neutron bombardment, was revealed that dwarfism is under the control of a major gene(designated as ndf1) with a mainly additive effect and non-significant(More)
Duckweed, with rapid growth rate and high starch content, is a new alternate feedstock for bioethanol production. The genetic diversity among 27 duckweed populations of seven species in genus Lemna and Spirodela from China and Vietnam was analyzed by ISSR-PCR. Eight ISSR primers generating a reproducible amplification banding pattern had been screened. 89(More)
BACKGROUND Landoltia punctata is a widely distributed duckweed species with great potential to accumulate enormous amounts of starch for bioethanol production. We found that L. punctata can accumulate starch rapidly accompanied by alterations in endogenous hormone levels after uniconazole application, but the relationship between endogenous hormones and(More)
G protein plays an important role in signal pathways and involved in various signal transduction systems in plant. A full-length cDNA encoding a putative G protein α subunit (Gα), designated as BnGA1, was isolated from Brassica napus. The expression of BnGA1 in different B. napus tissues and developmental stags was analyzed using real-time PCR. The results(More)
NK cells are innate lymphocytes that mediate early host defense against viruses, such as cytomegalovirus. IL-15 is upregulated during viral infections and drives the expansion of NK cells. However, the influence of IL-15 on murine NK cell division and death rates has not been quantitatively studied. Therefore, we developed a series of two-compartment(More)
BACKGROUND Duckweed is a novel aquatic bioenergy crop that is found ubiquitously throughout the world. Uniconazole plays an important role in improving crop production through the regulation of endogenous hormone levels. We found that a high quantity and quality of duckweed growth can be achieved by uniconazole application, although the mechanisms are(More)
OBJECTIVE This study aimed to determine the natural prevalence of variants of tyrosine-methionine-aspartic acid-aspartic acid (YMDD) motif in patients with chronic hepatitis B (CHB), and to explore its relation with demographic and clinical features, hepatitis B virus (HBV) genotypes, and HBV DNA levels. METHODS A total of 1,042 antiviral treatment naïve(More)
