BACKGROUND & OBJECTIVES Plasmodium falciparum cerebral malaria remains a major health problem in India. The efficacy of treatment of cerebral malaria lies in its early diagnosis through rapid diagnostic methods. ParaSights-F test detects HRP-2 antigen secreted by parasitised red blood cells and quantitative buffy coat assay (QBC) is examination of buffy coat for the presence of malarial parasit...

A PCR-based protocol for the detection of Leishmania (Viannia) parasites in canine blood, buffy coat, and bone marrow was developed and was then tested with field samples taken from a random sample of 545 dogs from villages in Peru where Leishmania (Viannia) braziliensis and Leishmania (Viannia) peruviana are endemic. Comparative tests with cultured parasites mixed with dog blood showed that th...

Exposure during fetal life may have long-lasting health consequences for the child. Cohorts with biological material are necessary to investigate the possible biological mechanisms behind this potential early programming of disease. The Aarhus Birth Cohort Biobank was established in 2008 as an amendment to an ongoing research database, the Aarhus Birth Cohort. It aims to provide the opportunity...

A cross sectional survey to determine the distribution and prevalence of trypanosomosis was conducted in Kindo Koisha district, in the Wollaita zone in southern Ethiopia. A total of 1 008 adult cattle was examined at eight different localities. Dark field examination of the buffy coat, as well as stained thin blood film examination and packed cell volume (PCV) evaluation were the diagnostic tec...

A high incidence of cytomegalovirus (CMV) infections is observed in Brazil. These viruses are causatives of significant morbidity and mortality among patients with advanced human immunodeficiency virus (HIV) infection. This work, shows the application of a PCR on determination of CMV load in the buffy coat and plasma. We analyzed the samples of 247 HIV infected patients in order to diagnose CMV...

In the leukocyte adherence inhibition (LAI) assay, about 34% of adherent T-cells from patients with breast cancer exhibit nonadherence to glass when incubated with extracts of autologous cancer but not with HLA-A, -B, and -C mismatched extracts of breast cancer. To determine whether the recognition by Tcells of tumor antigen was major histocompatibility complex restricted, major histocompatibil...

OBJECTIVE To compare postoperative complications in patients undergoing major surgery who received non-filtered or filtered red blood cell transfusions. DESIGN Prospective, randomised, double blinded trial. SETTING 19 hospitals throughout the Netherlands (three university; 10 clinical; six general). PARTICIPANTS 1051 evaluable patients: 79 patients with ruptured aneurysm, 412 patients und...

The promise of whole genome amplification (WGA) is that genomic DNA (gDNA) quantity will not limit molecular genetic analyses. Multiple displacement amplification (MDA) and the OmniPlex PCR-based WGA protocols were evaluated using 4 and 5 ng of input gDNA from 60 gDNA samples from three tissue sources (mouthwash, buffy coat, and lymphoblast). WGA DNA (wgaDNA) yield and genotyping performance we...

BACKGROUND Tissue factor (TF), the main activator of blood coagulation, is expressed on platelet surface and, together with procoagulant phospholipids, contributes to the global coagulation potential of these blood components. The present study evaluated, for the first time, the expression of TF on platelet surface during preparation and storage of platelet concentrates (PC) for transfusional u...

BACKGROUND UK Biobank will be collecting blood samples from a cohort of 500 000 volunteers and it is expected that the rate of collection will peak at approximately 3000 blood collection tubes per day. These samples need to be prepared for long-term storage. It is not considered practical to manually process this quantity of samples so an automated blood fractionation system is required. METH...
