objectives microscopy of giemsa-stained thick and thin peripheral blood smear (pbs) remains as the standard laboratory method for the diagnosis of symptomatic malaria. this study was done to compare pbs with polymerase chain reaction (pcr) method for detecting asymptomatic malaria parasitemia. patients and method blood samples were collected from 900 asymptomatic school children between 7-11 ye...

UNLABELLED Ochratoxin A (OTA) is a toxic secondary metabolite of fungi belonging to the Aspergillus and Penicillium genera, its presence in human blood being the primary indicator of exposure. AIM In the present study we determined OTA in 38 blood samples collected from healthy Romanian subjects of both genders. MATERIAL AND METHODS The OTA was determined through the direct, competitive, so...

Both prereduced molten agar and broth and aerobic molten agar and broth were inoculated with blood samples collected from patients with periodontitis, but in otherwise good health, both before and after extraction of two or more teeth. Postoperative blood samples from 23 of 25 patients sampled yielded anaerobic and facultative species. Colony counts from nine samples yielded from less than 1 to...

conclusions in samples stored in plastic syringes, overestimation of pao2 levels should be noted if samples cooled before analysis. in samples stored in plastic syringes, it is not necessary to store samples in iced water when analysis delayed up to one hour. results pao2 of the samples stored at 0°c was increased significantly after 60 minutes (p = 0.007). the paco2 of the samples kept for 30 ...

The detection of infective endocarditis (IE) of oral origin has been previously discussed. However, there are few reports confirming this infection using molecular biological techniques. We herein describe the case of a 67-year-old man who developed IE. Blood culture samples and strains obtained from the gingival and buccal mucosa showed 100% identity to Enterococcus faecalis JCM 5803 on sequen...

equine piroplasmosis is a tick-borne disease caused by intra-erythrocyte protozoa, theileria equi and babesia caballi. the present study aimed to detect piroplasm infection in horses in kurdestan province, iran, through molecular and microscopic approaches.n this study, 186 blood samples were randomly collected from horses of five regions of kurdestan province. the tbs-s/tbs-a primer set was us...

Evidence suggests that non-domesticated felids inherited the same AB-erythrocyte antigens as domestic cats. To study the possible compatibility of tiger blood with that of other endangered felidae, blood samples from captive tigers and domestic cats were subjected to an in vitro study. The objectives of this study were to (1) identify whether the captive tigers had blood type AB and (2) determi...

Diagnosis and treatment of circadian rhythm sleep-wake disorders both require assessment of circadian phase of the brain's circadian pacemaker. The gold-standard univariate method is based on collection of a 24-hr time series of plasma melatonin, a suprachiasmatic nucleus-driven pineal hormone. We developed and validated a multivariate whole-blood mRNA-based predictor of melatonin phase which r...
