Blood transfusion centers are under considerable pressure to produce platelet concentrates with high quality and safety due to the short shelf life of 3-5 days as well as possible bacterial and viral contaminations. For a variety of reasons, many Europeans have changed their methods of component production from whole blood using the North American standard platelet-rich plasma method to the buf...
Cord blood DNA methylation is associated with numerous health outcomes and environmental exposures. Whole cord blood DNA reflects all nucleated blood cell types, while centrifuging whole blood separates red blood cells, generating a white blood cell buffy coat. Both sample types are used in DNA methylation studies. Cell types have unique methylation patterns and processing can impact cell distr...
زمینه و هدف: پدیده پلاکت های اقماری (platelet satellitism, ps)، یک شکل رزت مانند از پلاکت ها در اطراف نوتروفیل ها بوده که به شکل وسیعی در نمونه هایcbc همراه با ضدانعقاد edta در دمای محیط مشاهده می شود. در این مطالعه اثر اتوآنتی بادی های ضدپلاکتی بر روی نوتروفیل ها و پلاکت های افراد سالم بررسی گردید. روش بررسی: در این مطالعه مورد - شاهدی، 10 فرد دارای پدیده پلاکت های اقماری انتخاب شدند. برای بر...
AIMS Alterations in mitochondrial DNA (mtDNA) have been implicated in carcinogenesis and tumor progression. We here evaluated the diagnostic and prognostic potential of mtDNA as a biomarker for breast cancer. METHODS Using multiplex real-time polymerase chain reaction, nuclear DNA (nDNA) and mtDNA levels in serum, buffy coat, tumor, and tumor-adjacent tissue samples from 50 breast cancer pati...
OBJECTIVE In this study are evaluated the usefulness of the buffy coat smear and panbacterial polymerase chain reaction (PCR) as diagnostic tests in the early detection of neonatal sepsis. MATERIAL AND METHODS It was studied 49 patients aged up to 28 days who were hospitalized in the Intensive Care Unit (ICUs) of the Neonatology, with a clinical diagnosis of neonatal sepsis and 49 umbilical c...
Sixty-five multiply transfused patients with severe aplastic anemia were given cyclophosphamide followed by grafts anemia were given cyclophosphamide followed by grafts from HLA-identical siblings. The effect of the administration of viable donor buffy coat cells following the marrow inoculum was evaluated with regard to graft rejection and survival. Results in 43 patients so treated are presen...

The greatest variance was seen with a Jamshidi needle were evaluated in the hypercellular or normocellular marin 53 children with leukemia or aplastic rows, as estimated by biopsy, in which anemia. Adequate specimens were ob39% were misinterpreted as moderately tamed in 85%. Results of cellularity estior severely hypocellular by aspirate. Volmat...
OBJECTIVE To analyze the DNA patterns extracted from plasma and nucleated blood cells (lymphocytes) in systemic sclerosis (SSc) with a new MFC DNA extracting kit. METHODS Ten SSc patients and 9 healthy controls were studied. Heparin containing blood samples were separated into plasma and buffy coat fractions and subjected to DNA extraction. The DNA pattern was revealed by 0.4% agarose electro...
The use of Gram type-specific PCR on buffy coat from clinical specimens for the detection of bacteraemia was evaluated for the first time using whole blood culture as the gold standard. In addition, the established buffy coat culture and whole blood PCR were also compared. Gram-positive bacteria belonging to six species and Gram-negative bacteria from 10 species were isolated and identified by ...
زمینه و هدف: پدیده پلاکتهای اقماری (Platelet Satellitism, PS)، یک شکل رزتمانند از پلاکتها در اطراف نوتروفیلها بوده که به شکل وسیعی در نمونههایCBC همراه با ضدانعقاد EDTA در دمای محیط مشاهده میشود. در این مطالعه اثر اتوآنتیبادیهای ضدپلاکتی بر روی نوتروفیلها و پلاکتهای افراد سالم بررسی گردید. روش بررسی: در این مطالعه مورد - شاهدی، 10 فرد دارای پدیده پلاکتهای اقماری انتخاب شدند. برای بر...
