1Spiking neural P systems with neuron division and budding显示文摘Spiking neural P systems are a class of distributed and parallel computing models inspired by spiking neurons.In this work,the features of neuron division and neuron budding are introduced into the framework of spiking neural P systems,which are processes inspired by neural stem cell division. With neuron division and neuron budding,a spiking neural P system can generate exponential work space in polynomial time as the case for P systems with active membranes.In this way,spiking neural P systems can efficiently solve computationally hard problems by means of a space-time tradeoff,which is illustrated with an efficient solution to SAT problem.PAN LinQiang PAUN Gheorghe PEREZ-JIMENEZ Mario J. 2011Science China(Information Sciences)2011,54,8:17
2Probiotic bacteria change Escherichia coli-induced gene expression in cultured colonocytes:Implications in intestinal pathophysiology显示文摘AIM: To investigate the change in eukaryotic gene expression profile in Caco-2 cells after infection with strains of Escherichia coli and commensal probiotic bacteria. METHODS: A 19 200 gene/expressed sequence tag gene chip was used to examine expression of genes after infection of Caco-2 cells with strains of normal flora E. coli,Lactobacillus plantarum,and a combination of the two. RESULTS: The cDNA microarray revealed up-regulation of 155 and down-regulation of 177 genes by E. coli . L. plantarum up-regulated 45 and down-regulated 36 genes. During mixed infection,27 genes were up-regulated and 59 were down-regulated,with nullification of stimulatory/inhibitory effects on most of the genes. Expression of several new genes was noted in this group. CONCLUSION: The commensal bacterial strains used in this study induced the expression of a large number of genes in colonocyte-like cultured cells and changed the expression of several genes involved in important cellular processes such as regulation of transcription,protein biosynthesis,metabolism,cell adhesion,ubiquitination,and apoptosis. Such changes induced by the presence of probiotic bacteria may shape the physiologic and pathologic responses they trigger in the host.Pinaki Panigrahi Gheorghe T Braileanu Hegang Chen O Colin Stine 2007World Journal of Gastroenterology2007,13,47:10

4皮革下脚料回收利用的生态学进展及预测显示文摘人类社会经济发展到一定水平,人类的生物本性开始退化,而逐渐由社会需求所代替,最终转化为对知识的渴求。工业产品的研制开发加强了产品对人类的保护促进。因此,对每一产品都应作出其生态系统方面的评价。忽视生产对生态系统的影响,便造成了生态危机。这种危机显示了人类对其赖以生存的大自然的天理侵犯。几乎整个大自然都受到工业生产的影响,从而打破自然界的平衡,最终又影响人类生存。Viorica Trandafir Gheorghe Trandafir 林涛 林茂楠 1993中国皮革1993,22,7:6

6Studies on Thermal Contraction of Crankshaft Bearings under Extreme Low Temperatures显示文摘This paper presents how the contractions of the main components of a V6 motor with low engine displacement are determined for the cold-start phase under extreme low temperature. Internal combustion engine components have complex geometries and to obtain the thermal contractions, in the research, used the method of finite element analysis. The phenomena of thermal contractions are studied for the cold-start situations at extreme low temperature, knowing that the cold-start phase of an internal combustion engine is the main factor that determines moving rotational and translational parts wear life. Checking the proper choice of clearance is particularly important, as the use of inappropriate values of it leads to rapid operation destruction of the engine group components. The results obtained for the thermal clearances of crankshaft bearings are mathematically modeled and the relations can be used for calculating the clearances. The mathematical models are also useful for implementing in different software tools.Sever-Alexandru Haba Gheorghe Oancea 2015Journal of Thermal Science2015,24,5:3
7Split-dose or hybrid nonsteroidal anti-inflammatory drugs and Nacetylcysteine therapy for prevention of post-retrograde cholangiopancreatography pancreatitis显示文摘BACKGROUND Despite significant technical and training improvements, the incidence of postendoscopic retrograde cholangiopancreatography(ERCP) pancreatitis(PEP) has not significantly dropped. Although many studies have evaluated the efficacy of various agents, e.g. nonsteroidal anti-inflammatory drugs, octreotide,antioxidants, administered via various dosages, routes(oral, intrarectal or parenteral), and schedules(before or after the procedure), the results have been conflicting.AIM To evaluate efficacy of three pharmacologic prophylactic methods for prevention of PEP.METHODS In this prospective, single-center randomized trial, patients who underwent firsttime ERCP for choledocholithiasis were randomly assigned to three groups. The first group received 600 mg N-acetylcysteine 15 min prior to ERCP, and perrectum administration of 50 mg indomethacin both prior to and after completion of the ERCP. The second group was administered only the 50 mg indomethacin per-rectum both prior to and after the ERCP. The third group was administeredper-rectum 100 mg indomethacin only after the ERCP, representing the control group given the guideline-recommended regimen. The primary end-point was PEP prevention.RESULTS Among the total 211 patients evaluated during the study, 186 fulfilled the inclusion criteria and completed the protocol. The percentages of patients who developed PEP in each of the three groups were not significantly different(χ2 =2.793, P = 0.247). Among the acute PEP cases, for all groups, 14 patients developed mild pancreatitis(77.77%) and 4 moderate. No severe cases of PEP occurred, and in all PEP cases the resolution was favorable. No adverse events related to the medications(digestive hemorrhage, rectal irritation, or allergies)occurred.CONCLUSION The efficacies of split-dose indomethacin and combined administration(Nacetylcysteine with indomethacin) for preventing PEP were similar to that of the standard regimen.Laura Pavel Gheorghe Gh Balan Alexandra Nicorescu Georgiana Emmanuela Gilca-Blanariu Catalin Sfarti Stefan Chiriac Smaranda Diaconescu Vasile Liviu Drug Gheorghe Balan Gabriela Stefanescu 2019World Journal of Clinical Cases2019,7,3:3
