A computer-assisted analysis of the spatial distribution of neurons having homogeneous characteristics is described in this paper. The camera lucida drawings of sections of a brain nucleus and the points representing the neurons labeled on the basis of a specific behavior of discharge rates were digitized on a personal computer Amiga 2000 or IBM compatible. Our software provided: a) the computerized, stereotaxically oriented reconstruction of the stored sections and of the plotted neurons; b) the identification within each section of the mass center (MC) of the units sharing a given behavior and of the area where the density of such neurons was maximal (MDA). The routine was tested on the spatial distribution of neuronal responses to serotonin in the lateral vestibular nucleus. 相似文献

The CHS2 and CHS3 genes of Candida albicans were disrupted. The double disruptant was still viable. Assessment of chitin and of calcofluor white resistance shows that CHS1 is responsible for septum formation and CHS3 is responsible for overall chitin synthesis otherwise. There were only small differences in virulence to immunocompromised mice of homozygous chs2 delta amd chs3 delta null mutants. 相似文献

The effect of N-methylphosphatidylethanolamine on phase transition and the fluidity of the liposomes made of dipalmitoylphosphatidylcholine or phosphatidylethanolamine was studied by the steady-state fluorescence polarization method and differential scanning calorimetry. N-methylation of phosphatidylethanolamine caused a decrease of fluidity of liposomes made of dipalmitoylphosphatidylcholine, but had little effect on dipalmitoylphosphatidylethanolamine. The liposomes prepared with both phosphatidylcholine and N-methylphosphatidylethanolamine and also phosphatidylethanolamine and N-methylphosphatidylethanolamine could be composed of solid solution and exhibited symmetric phase diagram. 相似文献

Pancreatic tumors are hypovascular, which leads to a poor nutrient supply to support the aggressively proliferating tumor cells. However, human pancreatic cancer cells have extreme resistance to nutrition starvation, which enables them to survive under severe metabolic stress conditions within the tumor microenvironment, a phenomenon known as “austerity” in cancer biology. Discovering agents which can preferentially inhibit the cancer cells’ ability to tolerate starvation conditions represents a new generation of anticancer agents. In this study, geranyl 2,4-dihydroxy-6-phenethylbenzoate (GDP), isolated from Boesenbergia pandurata rhizomes, exhibited potent preferential cytotoxicity against PANC-1 human pancreatic cancer cells under nutrition starvation conditions. GDP also possessed PANC-1 cell migration and colony formation inhibitory activities under normal nutrient-rich conditions. Mechanistically, GDP inhibited PI3K/Akt/mTOR/autophagy survival signaling pathway, leading to selective PANC-1 cancer cell death under the nutrition starvation condition. Therefore, GDP is a promising anti-austerity agent for drug development against pancreatic cancer. 相似文献

Microbial communities in ancient marine sediments composed of clay and silt obtained from the terrestrial subsurface were phylogenetically analyzed based on their 16S rRNA gene sequences. Chloroflexi and Miscellaneous Crenarchaeotic Group were predominant in bacterial and archaeal clone libraries, respectively. Of 44 operational taxonomic units (OTUs) that had close relatives in the database, 30 were close to sequences obtained from marine environments. Some sequences belonged to the candidate groups JS1, ANME-I, and Marine Benthic Group-C, which are typically found in marine sediments. Low chloride concentrations in the sediments suggest that these marine-affiliated sequences may not reflect currently active microbial communities. Our results indicate the existence of long-term preserved DNA or descendants of ancient oceanic microbial components in subsurface muddy sediments in a temperate region, which may reflect indigenous population of paleoenvironments. 相似文献

Dietary plant protein is well known to reduce serum cholesterol levels. Rice bran is a by-product of rice milling and is a good source of protein. The present study examined whether feeding rats a high-cholesterol diet containing 10% rice bran protein (RBP) for 10 d affected cholesterol metabolism. Rats fed dietary RBP had lower serum total cholesterol levels and increased excretion of fecal steroids, such as cholesterol and bile acids, than those fed dietary casein. In vitro assays showed that RBP strongly bound to taurocholate, and inhibited the micellar solubility of cholesterol, compared with casein. Moreover, the bile acid-binding proteins of the RBP were eluted by a chromatographic column conjugated with cholic acid, and one of them was identified as hypothetical protein OsJ_13801 (NCBI accession No. EAZ29742) using MALDI-TOF mass spectrometry analysis. These results suggest that the hypocholesterolemic action of the RBP may be caused by the bile acid-binding proteins. 相似文献
