Fourteen Gram-stain-positive bacterial strains were isolated from Chinese traditional pickle and yogurt. The strains were characterized using a polyphasic taxonomic approach, including 16S rRNA gene sequence analysis, gene sequence analysis, gene sequence analysis, fatty acid methyl ester analysis, determination of DNA G+C content, determination of average nucleotide identity (ANI), DNA-DNA hybridization (DDH) and an analysis of phenotypic features. The data demonstrated that the 14 strains represented ten novel species belonging to the genus , strains 73-4, 247-3, 143-4(a), 33-1, 143-6, 247-4, 17-4, 143-1, 735-2 and M1530-1 were designated as the type strains.

Thirty Gram-stain-positive bacterial strains were isolated from Chinese traditional pickle. The strains were characterized using a polyphasic taxonomic approach, including 16S rRNA gene sequence analysis, pheS gene sequence analysis, rpoA gene sequence analysis, fatty acid methyl ester analysis, determination of DNA G+C content, determination of average nucleotide identity (ANI), in silico DNA-DNA hybridization (isDDH), determination of average amino acid identity (AAI) and an analysis of phenotypic features. The data demonstrated that the 30 strains represented 11 novel species belonging to the genus Lactobacillus, strains 159-4, 47-3, 257-1, 187-3, 220-4, 151-2B, 137-3, 244-4, 218-10, 218-6 and 112-3 were designated as the type strains.

Intercropping of maize and potato, as an important intercropping planting pattern, has a prominent advantage of resource utilization and yield. However, contribution of nutrient uptake and utilization to crop yield advantage and its response to N application rates remain unclear. Through a 2-year plot experiment, including maize monoculture, potato monoculture and maize intercropping with potato at 4 N-fertilized levels of N(0 kg·hm), N(125 kg·hm), N(250 kg·hm) and N(375 kg·hm), nutritional contribution of yield advantage of intercropping was studied.

To explore the effects of light intensity on photosynthetic characteristics and light adaptation of the shade-demanding species Panax notoginseng, the responses of photosynthesis to photosynthetic photon flux density, CO and sunflecks in the two-year-old Panax notoginseng were investigated under different levels of light intensity (29.8%, 9.6%, 5.

Unlabelled: Although dietary fibers contribute to health and physiology primarily via the fermentative actions of the gut microbiota of the hosts, few studies have focused on how these interactions influence the metabolic status of sows. Here, the effects of inclusion of konjac flour (KF) in a gestation diet on oxidative stress status, insulin sensitivity, and gut microbiota were investigated to elucidate the correlation between the microbiota and metabolic changes in sows. Sows were assigned to either control or 2.

Ratoon sugarcane plantlets in southern China have suffered a serious chlorosis problem in recent years. To reveal the causes of chlorosis, plant nutrition in chlorotic sugarcane plantlets and the role of manganese (Mn) in this condition were investigated. The study results showed that the pH of soils growing chlorotic plantlets ranged from 3.

Fifty-four multiparous large white sows were used to determine the effects of supplementing oregano essential oil (OEO) to the gestation and lactation diets on oxidative stress status, lactation feed intake, and their piglet performance. Two groups were fed diets with (OEO; n = 28) or without (Control; n = 26) supplemental 15 mg/kg OEO during gestation and lactation. The serum levels of reactive oxygen species (ROS) (P < 0.

Aims: Calcification in adamantinomatous craniopharyngioma (ACP) is troublesome for surgical intervention. The aim of this study was to examine the osteogenic proteins that play important roles in the calcium deposition of the odontogenic/osteogenic tissues in craniopharyngioma.

Methods And Results: Craniopharyngiomas (n = 89) were investigated for the presence and expression pattern of the osteoinductive/odontoinductive factor bone morphogenetic protein-2 (Bmp2) and two osteoblastic differentiation makers, Runt-related transcription factor-2 (Runx2) and Osterix, using immunohistochemistry and Western blotting.

Background: Development of efficient therapies of lung cancer and deep understanding of their anti-tumor mechanism are very important. The aim of the present study is to investigate the therapeutic effect of microRNA-22 (miR-22) on lung cancer using in vitro and in vivo methods.

Methods: Expression level of miR-22 in lung cancer specimens and relative normal tissues was detected by microRNA-specific quantitative real-time PCR (Q-PCR).

Background: To investigate the effects of matrine on the vascular smooth muscle cell (VSMC) migration modulated by disturbed flow and their underlying molecular mechanisms in vitro.

Methods: Isolated rat aortic VSMCs were grown to confluence on 20- × 80-mm fibronectin-coated glass cover slides, and then, denuded zones were made at the position calculated to be the oscillating flow-reattachment zone and also in the downstream laminar flow region. VSMCs were treated with different doses of matrine (0, 10, 20, 30, and 40 mg/L), or PD98059 (30 μM), ML-7 (10 μM) combined with matrine (40 mg/L) for 30 minutes before and during the experiments.

Mesenchymal stem cells (MSC) derived from bone marrow can potentially reduce the acute inflammatory response in spinal cord injury (SCI) and thus promote functional recovery. However, the precise mechanisms through which transplanted MSC attenuate inflammation after SCI are still unclear. The present study was designed to investigate the effects of MSC transplantation with a special focus on their effect on macrophage activation after SCI.

Aims: It is generally accepted that the oxidative stress and the proliferative activity of vascular smooth muscle cells (VSMCs) contribute to the pathogenesis of neointimal hyperplasia after vascular injury. Although β-elemene (β-1-methyl-1-vinyl-2, 4-diisopropenyl-cyclohexane) has been used as an antitumour drug, its therapeutic effect on vascular diseases has not yet been determined. In this study, we investigated whether β-elemene could inhibit oxidative damage of vascular endothelial cells, suppress VSMCs growth and prevent neointimal hyperplasia.

Aim: To investigate the effect of matrine on proliferation of vascular smooth muscle cells (VSMCs) and elucidate the underlying mechanisms.

Methods: Rat aortic VSMCs were cultured in medium supplemented with 10% fetal bovine serum and treated with various concentrations (0, 5, 10, 15, and 20 mg/L) of matrine for 72 h. VSMCs proliferation and cell cycle profiling were assessed using a methylene blue incorporation assay and flow cytometry, respectively.

The aim of this study was to determine the molecular mechanism underlying the inhibition of vascular restenosis by Radix Sophorae Flavescentis (RSF) extract after balloon dilatation injury. In a rat carotid model of balloon dilatation injury, the RSF extract showed a significant inhibitory effect on vascular restenosis. Immunohistochemistry showed that the expression of tumor necrosis factor-alpha (TNF-alpha) in the vascular focus was markedly reduced upon treatment with the RSF extract, whereas the expression of proliferating cell nuclear antigens (PCNA) was mostly unaffected.

The synthetic compound NO-1886 is a lipoprotein lipase activator that lowers plasma triglycerides and elevates high-density lipoprotein cholesterol (HDL-C). Recently, the authors found that NO-1886 also had an action of reducing plasma glucose in high-fat/high-sucrose diet-induced diabetic rabbits. In the current study, we investigated the effects of NO-1886 on insulin resistance and beta-cell function in rabbits.
