Lymphocyte heterogeneity was studied in peripheral blood and salivary gland lesions in 24 patients with Sjögren's syndrome. Peripheral blood B cells, measured by immunofluorescence with specific antiserum to immunoglobulins or by rosette assay with complementcoated erythrocytes, were increased in most patients. Peripheral blood T cells, measured by immunofluorescence with rabbit antiserum to hu...

OBJECTIVE The aim of this study was to determine micronucleus (MN) frequencies in exfoliated cervical cells and peripheral blood lymphocytes of women with polycystic ovarian syndrome (PCOS). MATERIALS AND METHODS Fifteen patients with PCOS and 11 healthy control patients were included in the study. Cervical smears and peripheral blood were collected from all patients. Specimens were analyzed ...

Gas chromatography (GC) and immunoassay techniques applied to blood and urine specimens were compared for the screening of benzodiazepines in postmortem forensic toxicology. Five hundred and six such successive postmortem cases in which both urine and peripheral blood was sent for toxicological analysis by the medical examiners were selected. The urine specimens were tested by the Emit((R)) d.a...

The presence of tumor cells in peripheral blood is being regarded increasingly as a clinically relevant prognostic factor for colorectal cancer patients. Current molecular methods are very sensitive but due to low specificity their diagnostic value is limited. This study was undertaken in order to systematically identify and validate new colorectal cancer (CRC) marker genes for improved detecti...

Feline immunodeficiency virus (FIV) infection in cats results in life-long viral persistence and progressive immunopathology. We have previously described a cohort of experimentally infected cats demonstrating a progressive decline of peripheral blood CD4+ T-cell over six years in the face of apparent peripheral viral latency. More recently we reported findings from this same cohort that reveal...

This study investigated the correlation between biochemical markers and viral load among 38 measles cases, including 15 immunologically naive patients 23 with secondary vaccine failure (SVF). We examined four markers, namely, aspartate aminotransferase, alanine C-reactive protein, lactate dehydrogenase (LDH) their relationship virus genome copy numbers in peripheral blood mononuclear cells (PBM...

A novel, easy to perform PCR-based method employing specific DNA methylation biomarkers to detect B-cell neoplasms in a variety of B-cell lines and B lymphoblastic leukemia (B-ALL) patient specimens has been developed. This method detects as few as 5 B-ALL cells, or 1 B-ALL cell in 1,000,000 normal background blood cells using a single marker, DLC-1 gene CpG island (CGI) methylation. By adding ...

Colonies that contain granulopoietic and erythropoietic cells can be grown in specimens of human bone marrow, peripheral blood, and cord blood. Growth of these colonies is promoted by media conditioned by leukocytes in the presence of phytohemagglutinin (PHA-LCM) and the addition of erythropoietin on days 4 or 5 to the cultures. Sedimentation velocity profiles for these granuloerythrocytic colo...

Subspecific typing of clinical meningococcal strains is important in the investigation of outbreaks and for disease surveillance. Serogrouping, typing, and subtyping of strains currently require isolation of a meningococcus from one or more clinical specimens. However, the increasing widespread practice of preadmission administration of parenteral antibiotics has resulted in a decrease in the f...
