Background and Aims: As the incidence of bacteraemia is on rise and it contributes to significant morbidity and mortality, so early diagnosis and appropriate treatment of blood stream infections is essential. The present study was aimed to know the prevalence and antimicrobial susceptibility pattern of blood isolates. methods: A total of 9010 specimens of blood received for culture during one y...

use for each and every act of intercourse.4 The use of condoms is recommended for individuals who have multiple partners, who have a primary partner who is infected, or who have a partner whose serostatus is unknown,5 although the absolute amount of protection they provide has not been accurately established. The effectiveness of the condom as a contraceptive provides insight into its usefulnes...

Volume 29, Number 6, November/December 1997 tive pills (the first 21 of each 28-day cycle) without interruption. Oral contraceptive protection is expected to decrease when two or more consecutive hormonally active pills are skipped.3 It is not uncommon for prolonged intervals to occur between doses of self-administered medication.4 Between one-third and one-half of users of medications in pill ...

The prevalence of antibodies to Toxoplasma gondii was conducted in 300 buffaloes from Ahvaz, Kouzestan province, south west of Iran. Blood sera were screened using a Modified agglutination test (MAT) incorporating 2-mercaptoethanol. Positive reactions in sera dilutions above 1:25 were considered as indicative for the presence of T. gondii antibodies. The overall prevalence of infection in the a...

Objective: The mechanism by which elevated extracellular potassium ion concentration ([K+]o) causes dilation of skeletal muscle arterioles was evaluated. Methods: Arterioles (n = 111) were hand-dissected from hamster cremaster muscles, cannulated with glass micropipettes and pressurized to 80 cm H2O for in vitro study. The vessels were superfused with physiological salt solution containing 5 mM...

Metastasis is the main cause of mortality in individuals with cancer. Thus, the identification of genes that are important for this process is essential. We used Affymetrix gene expression profiling of human colorectal adenocarcinomas to identify genes whose expression characterizes metastatic tumors. Following laser capture microdissection we isolated RNA from metastasizing and non-metastasizi...

Cell-surface F1F0-ATP synthase was involved in the cell signaling mediating various biological functions. Recently, we found that cell-surface F1F0-ATP synthase plays a role on intracellular triacylglycerol accumulation in adipocytes, and yet, the underlying mechanisms remained largely unknown. In this study, we investigated the role of extracellular ATP on the intracellular triacylglycerol acc...
