This study presents a 7-year retrospective analysis of seasonal variations in the prevalence of Cryptococcus neoformans var. grubii and Cryptococcus gattii in decayed wood inside trunk hollows of 518 trees belonging to 20 species in north-western India during 2000-2007. Of the 1,439 wood samples investigated, 406 (28.2%) were found to be positive for the Cryptococcus neoformans species complex ...

The effect of repetitive stimulation on synaptic transmission was studied in the isolated superior cervical ganglion of the rabbit under conditions of reduced quantal content. Excitatory postsynaptic potentials (EPSP) were recorded with the sucrose gap technique to obtain estimates of transmitter release. Four components of increased transmitter release, with time constants of decay similar to ...

BACKGROUND Several lines of evidence indicate that oral microbial flora play a critical role in the pathogenesis of Behçet disease. Saliva flow rate, buffer capacity and microorganism content are very important in the maintenance of oral health. AIMS We aimed to evaluate saliva flow rate, pH, buffer capacity and Streptococcus mutans and Lactobacilli content along with the decayed, missing, an...

INTRODUCTION Little is known on the prevalence of tooth decay among pregnant women. Better knowledge of tooth decay risk indicators during pregnancy could help to develop follow-up protocols for women at risk, along with better prevention strategies. The aim of this study was to assess the frequency of tooth decay and the number of decayed teeth per woman in a large sample of pregnant women in ...

SUMMARY Sodium azide, 2,4-dinitrophenol and iodoacetate did not inhibit hydrolysis of lactose by cell-free preparations of Sacchuromyces fragilis ,8-galactosidase, but with intact organisms fermentation and hydrolysis were inhibited to a similar extent. This suggests that these inhibitors may interfere with the transport of lactose into the cell. Galactose fermentation was inhibited by sodium a...

The Department of Pedagogy of the University of Pennsylvania conducted during the summer of 1909 a School of Observation for teachers, comprising seven graded classes containing a hundred and fifty-six pupils. These children attended the school usually for the purpose of qualifying for the grade higher than that occupied in June at the closing of the public school. Some of them had failed of pr...

OBJECTIVE The purpose of this study was to analyze dental caries experience of adults living in the southeastern state of São Paulo, Brazil, according to some socio-demographic conditions of this population. MATERIAL AND METHODS The sample consisted of 1,159 school teachers and workers (35 to 44 years old) from 29 cities of the state of São Paulo, Brazil. RESULTS 92.3% were dentate and the ...

The intravascular metabolism of the cholesteryl ester moiety of rat plasma LDL, HDL1, and HDL2 was determined in intact male rats. Biosynthetically labeled lipoproteins were prepared by zonal ultracentrifugation from the plasma of rats injected with [3H]cholesterol. The lipoproteins were concentrated by vacuum ultrafiltration as other procedures were found to alter the biological properties of ...
