The functional capacity of human breast milk phagocytes was evaluated with both bactericidal and biochemical assays. Acridine orange was used as a vital stain for bacteria to directly visualize phagocytosis and killing. Bactericidal capabilities were further examined by colony count and chemiluminescent methods. Cytocentrifuged specimens stained for myeloperoxidase exhibited enzyme activity in ...

BACKGROUND Wound healing is a complex and dynamic process following damage in tissue structures. Due to extensive skin damage caused by burn injuries, this study determined the role of human adult peripheral and umbilical cord blood platelet-rich plasma on proliferation and migration in human skin fibroblasts. METHODS Platelet-rich plasma (5, 10, 15, 20 and 50% PRP) from human umbilica...

background one-third of the world’s population is infected with mycobacterium tuberculosis. investigation of toll-like receptors (tlrs) has revealed new information regarding the immunopathogenesis of this disease. toll-like receptors can recognize various ligands with a lipoprotein structure in the bacilli. toll-like receptor 2 and tlr-4 have been identified in association with tuberculosis in...

objectives the cause of rheumatoid arthritis (ra) as a chronic inflammatory autoimmune disease is still unknown. it appears that both genetic and environmental factors play a role in its pathogenesis. recent studies reveal that in addition to the cns, immune cells synthesis neurotransmitters so that these catecholamines can regulate immune functions. the aim of this study is to evaluate the dop...

Molecular analysis of clinical samples has been hampered by the lack of fresh or frozen specimens and the presence of contaminating background cells within samples obscuring the molecular analysis of the pathological cells of interest. Routine cytology specimens are a ubiquitous and abundant, yet largely untapped, source of clinical samples for molecular analysis. Morphologically defined single...

This paper presents an effective color normalization method for thin blood film images of peripheral blood specimens. Thin blood film images can easily be separated to foreground (cell) and background (plasma) parts. The color of the plasma region is used to estimate and reduce the differences arising from different illumination conditions. A second stage normalization based on the database-gra...

the aim of this study was to assess the predictive effect of the ebmt risk score on the outcomes of allogeneic stem cell transplantation in a relatively homogenous group of acute myelogenous leukemia (aml) patients regarding the occurrence of acute and chronic graft versus host disease (gvhd). this historical cohort study included adult patients (≥ 15 years old) with aml (n=363) who received al...

Previously, we demonstrated that replication in restenotic coronary atherectomy specimens was an infrequent and modest event. In general, this data was interpreted with caution, as immunocytochemistry for the proliferating cell nuclear antigen (PCNA) was used to subjectively assess proliferation and most of the tissue specimens were resected more than 3 months after the initial interventional p...

BACKGROUND Most cutaneous T-cell lymphomas demonstrate a malignant population with a CD4(+) phenotype. In rare cases, CD8(+) phenotypes have been described based on immunostaining of skin specimens. Although some CD8(+) lymphomas have an indolent course, others, such as CD8(+) epidermotropic cytotoxic T-cell lymphomas, are typically more aggressive. To our knowledge, involvement of peripheral b...
