5Antibiotic Resistance of Probiotic Strains of Lactic Acid Bacteria Isolated from Marketed Foods and Drugs显示文摘Objective To identify the antimicrobial resistance of commercial lactic acid bacteria present in microbial foods and drug additives by analyzing their isolated strains used for fermentation and probiotics. Methods Antimicrobial susceptibility of 41 screened isolates was tested with disc diffusion and E-test methods after species-level identification. Resistant strains were selected and examined for the presence of resistance genes by PCR. Results Distribution of resistance was found in different species. All isolates were susceptible to chloramphenicol, tetracycline, ampicillin, amoxicillin/clavulanic acid, cephalothin, and imipenem. In addition, isolates resistant to vancomycin, rifampicin, streptomycin, bacitracin, and erythromycin were detected, although the incidence of resistance to these antibiotics was relatively low. In contrast, most strains were resistant to ciprofloxacin, amikacin, trimethoprim/sulphamethoxazole, and gentamycin. The genes msrC, vanX, and dfrA were detected in strains of Enterococcus faecium, Lactobacillus plantarum, Streptococcus thermophilus, and Lactococcus lactis. Conclusion Antibiotic resistance is present in different species of probiotic strains, which poses a threat to food safety. Evaluation of the safety of lactic acid bacteria for human consumption should be guided by established criteria, guidelines and regulations.CHANG LIU, ZHUO-YANG ZHANG, KE DONG, JIAN-PING YUAN, AND XIAO-KUI GUO P1 P Department of Medical Microbiology and Parasitology, Institutes of Medical Sciences, Shanghai Jiao Tong University School of Medicine, Shanghai 200025, China 2009Biomedical and Environmental Sciences2009,22,5:19
6Prediction of atrial fibrillation development and progression:current perspectives显示文摘Atrial fibrillation(AF) is the most common arrhythmia in clinical practice. Several conventional and novel predictors of AF development and progression(from paroxysmal to persistent and permanent types) have been reported. The most important predictor of AF progression is possibly the arrhythmia itself. The electrical, mechanical and structural remodeling determines the perpetuation of AF and the progression from paroxysmal to persistent and permanent forms. Common clinical scores such as the hypertension, age ≥ 75 years, transient ischemic attack or stroke, chronic obstructive pulmonary disease, and heart failure and the congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke/transient ischemic attack, vascular disease, age 65-74 years, sex category scores as well as biomarkers related to inflammation may also add important information on this topic. There is now increasing evidence that even in patients with so-called lone or idiopathic AF, the arrhythmia is the manifestation of a structural atrial disease which has recently been defined and described as fibrotic atrial cardiomyopathy. Fibrosis results from a broad range of factors related to AF inducing pathologies such as cell stretch, neurohumoral activation, and oxidative stress. The extent of fibrosis as detected either by late gadolinium enhancement-magnetic resonance imaging or electroanatomic voltage mapping may guide the therapeutic approach based on the arrhythmia substrate. The knowledge of these risk factors may not only delay arrhythmia progression, but also reduce the arrhythmia burden in patients with first detected AF. The present review highlights on the conventional and novel risk factors of development and progression of AF.Konstantinos Vlachos Konstantinos P Letsas Panagiotis Korantzopoulos Tong Liu Stamatis Georgopoulos Athanasios Bakalakos Nikolaos Karamichalakis Sotirios Xydonas Michael Efremidis Antonios Sideris 2016World Journal of Cardiology2016,8,3:16

11Notch signaling controls chondrocyte hypertrophy via indirect regulation of Sox9显示文摘RBPjk-dependent Notch signaling regulates both the onset of chondrocyte hypertrophy and the progression to terminal chondrocyte maturation during endochondral ossification. It has been suggested that Notch signaling can regulate Sox9 transcription, although how this occurs at the molecular level in chondrocytes and whether this transcriptional regulation mediates Notch control of chondrocyte hypertrophy and cartilage development is unknown or controversial. Here we have provided conclusive genetic evidence linking RBPjk-dependent Notch signaling to the regulation of Sox9 expression and chondrocyte hypertrophy by examining tissuespecific Rbpjk mutant(Prx1Cre;Rbpjkf/f), Rbpjk mutant/Sox9 haploinsufficient(Prx1Cre;Rbpjkf/f;Sox9f/1),and control embryos for alterations in SOX9 expression and chondrocyte hypertrophy during cartilage development. These studies demonstrate that Notch signaling regulates the onset of chondrocyte maturation in a SOX9-dependent manner, while Notch-mediated regulation of terminal chondrocyte maturation likely functions independently of SOX9. Furthermore, our in vitro molecular analyses of the Sox9 promoter and Notch-mediated regulation of Sox9 gene expression in chondrogenic cells identified the ability of Notch to induce Sox9 expression directly in the acute setting, but suppresses Sox9 transcription with prolonged Notch signaling that requires protein synthesis of secondary effectors.Anat Kohn Timothy P Rutkowski Zhaoyang Liu Anthony J Mirando Michael J Zuscik Regis J O'Keefe Matthew J Hilton 2015Bone Research2015,3,3:8
12未固结流砂地层采油过程中出砂情况模拟实验显示文摘为了研究未固结流砂储集层在采油过程中的出砂情况和影响出砂的主要因素,进行了不同条件下的出砂过程模拟实验。使用水洗白砂、黏土(高岭土)和蒸馏水制成未固结流砂地层模型,利用新开发的出砂模拟装置进行了模拟实验,并分析了作用于地层的拖曳力和地层胶结特征对出砂的影响。研究表明,随着拖曳力的增加,出砂速度和产油速度都加快;随着胶结物含量的增加,出砂量和产油量明显降低,甚至在胶结物含量较高的情况下出砂量几乎为零。地层压力大的油藏在开采期间由于产生了较大的拖曳力更可能出砂,而拖曳力和有效地层应力共同影响油藏的总体产油量。可以根据地层黏土含量估计出砂情况,从而通过采取适当的防砂措施尽可能减少出砂量。某些情况下油藏比气藏更容易出砂。PERERA M S A RANJITH P G RATHNAWEERA T D DE SILVA G P D LIU T 2017石油勘探与开发2017,44,5:8

18Species Exclusion Between an Invasive and an Indigenous Whitefly on Host Plants with Differential Levels of Suitability显示文摘The whitefly Bemisia tabaci has risen to international prominence since the 1980s due to the rapid spread around the globe by the two species B and Q within this species complex.The invasion of B has often been associated with the displacement of indigenous whiteflies.As the genetic structure of B.tabaci is diverse,more case studies of the competitive relationships between B and indigenous species of the whitefly species complex will help to understand further the mechanisms underlying the invasion of B.We examined the competitive interactions between B and ZHJ2,a widely distributed indigenous whitefly in Asia,on host plants with differential levels of suitability to the two species in the laboratory,and also tested the effect of insecticide application on the competitive relationships.Three species of plants were tested including cotton,a plant showing similar levels of suitability to both species,squash,a plant showing higher suitability to B than to ZHJ2,and kidney bean,a plant showing higher suitability to ZHJ2 than to B.In the case of no insecticide application,B displaced ZHJ2 on cotton,squash,and kidney bean by the 6th,3rd and 10th generation,respectively.With the application of imidacloprid,the displacement of ZHJ2 by B on cotton occurred by the 5th generation.As the displacement progressed,the proportion of B females increased,and the proportion of ZHJ2 females decreased on cotton and squash.In contrast,on kidney bean the proportion of B females remained unchanged while that of ZHJ2 increased.These results show the strong capacity of the invasive B to displace ZHJ2,and indicate that host plants with differential levels of suitability to the two species may affect the speed but not the trend of displacement and insecticide application may accelerate the process of displacement.LUAN Jun-bo XU Jing LIN Ke-ke Myron P Zalucki LIU Shu-sheng 2012Journal of Integrative Agriculture2012,11,2:6

20Are hyoliths Palaeozoic lophophorates?显示文摘The phylogenetic position of hyoliths has long been unsettled,with recent discoveries of a tentaculate feeding apparatus('lophophore')and fleshy apical extensions from the shell('pedicle')suggesting a lophophorate affinity.Here,we describe the first soft parts associated with the feeding apparatus of an orthothecid hyolith,Triplicatella opimus from the Chengjiang biota of South China.The tuft-like arrangement of the tentacles of T.opimus differs from that of hyolithids:suggesting they collected food directly from the substrate.A reassessment of the feeding organ in hyolithids indicates that it does not represent a lophophore and our analysis of the apical structures associated with some orthothecids show that these represent crushed portions of the shell and are not comparable to the brachiopod pedicle.The new information suggests that hyoliths are more likely to be basal members of the lophotrochozoans rather than lophophorates closely linked with the Phylum Brachiopoda.Fan Liu Christian B Skovsted Timothy P Topper Zhifei Zhang Degan Shu 2020National Science Review2020,7,2:5
