I. The degree of electrotonic coupling between a given synapse located on a dendrite and the spike trigger zone is a major determinant of the relative influence of that synapse on neuronal firing. The degree of electrotonic coupling between a synapse and the recording site also influences the measurement of the biophysical properties of that synapse. We present theoretical justification for a p...

Eğitim, yalnızca okulla sınırlandırılamayacak kadar geniş kapsamlı bir kurumdur. Bununla
 birlikte eğitim kurumu deyince akla gelen okul, bireylerin yaşamları boyunca edinecekleri pek
 çok becerinin de verilmesi bakımından oldukça değerlidir. K12 süreci bu becerilerin edinilmesi
 hususunda değerli yıllardır. Özellikle toplumsal değişim ve dönüşüm göz önünde
 bulundurulduğund...

Colonization of barley plants by the food-borne pathogens Salmonella enterica serovar typhimurium and three Listeria spp. (L. monocytogenes, L. ivanovii, L. innocua) was investigated in a monoxenic system. Herbaspirillum sp. N3 was used as a positive control and Escherichia coli HB101 as a negative control for endophytic root colonization. Colonization of the plants was tested 1-4 weeks after i...

purpose: to evaluate the properties of cultured limbal stem cells for corneal surface reconstruction. methods: specimens of limbal explants were prepared from the eye bank of i.r. iran. the explants were cultured and expanded on acellular amniotic membrane for 21 days. the cultured cells were evaluated for expression of connexin 43 and keratinine k3 by immunocytochemistry and expression of k12 ...

Surfactant protein (SP) D functions as a soluble pattern recognition molecule to mediate the clearance of pathogens by phagocytes in the innate immune response. We hypothesize that SP-D may also interact with dendritic cells, the most potent antigen presenting cell, to enhance uptake and presentation of bacterial antigens. Using mouse bone marrow-derived dendritic cells, we show that SP-D binds...

Inducible nitric oxide synthase (iNOS)-deficient mice were used to examine the role of iNOS in Escherichia coli-induced urinary tract infection (UTI). The toxicity of nitric oxide (NO)/peroxynitrite to bacteria and host was also investigated. The nitrite levels in urine of iNOS+/+ but not iNOS/ mice increased after infection. No differences in bacterial clearance or persistence were noted betwe...

Flow Microcalorimetry, E. coli K12, Aerobic Chemostat Culture The combination of a 3-liter fermentor with a flow-through calorimeter is described. Minimum time-lags are less than 10 s corresponding to maximum thermal peak disturbances of ~ 4 jiW. The set up shows an excellent long time stability. Aerobic growth of Escherichia coli K12 in batch cultures was used to test the equipment. Precision ...
