We induced mild blunt and blast injuries in rats using a custom-built device and utilized in-house diffusion tensor imaging (DTI) software to reconstruct 3-D fiber tracts in brains before and after injury (1, 4, and 7 days). DTI measures such as fiber count, fiber length, and fractional anisotropy (FA) were selected to characterize axonal integrity. In-house image analysis software also showed ...

Despite a high degree of homonomy in the segmental organization of the ectoderm, the body plan of the leech is divided into two zones based on the distinct cell lineage patterns that give rise to the O/P portion of the segmental ectoderm. In the midbody and caudal segments, each segmental repeat of ectoderm arises in part from one 'o' blast cell and one 'p' blast cell. These two blast cells are...

Background: The vascular response to recurrent tissue hypoxia and reperfusion following red blood cell sickling causes acute chest syndrome and chronic lung disease. The purpose of this study was to determine the pattern of chronic lung lesions and possible risk factors in sickle cell patients in lagos, Nigeria.Methods: From July 2012 to April 2013, Pulmonary function test (PFT) and chest-x-ray...

The classification of myelodysplastic syndromes is based on the morphological criteria proposed by the French-American-British (FAB) and World Health Organization (WHO) groups. Accurate enumeration of blast cells, although essential for diagnosis of myelodysplastic syndrome and for assignment to prognostic groups, is often difficult, due to imprecise criteria for the morphological definition of...

The fate, proliferation, and developmental potentialities of cell suspensions made from white pulp containing large germinal centers have been studied in the mouse by transfer of cells labeled with thymidine-(3)H to lethally irradiated, syngeneic recipients. Radioautographic analyses were made using both smears and sections of a variety of tissues. Thymidine-(3)H-labeling patterns of white pulp...

BACKGROUND: Immune thrombocytopenia (ITP) can precede the onset of systemic lupus erythematosus (SLE) by months to years. CASE PRESENTATION: A 12-year-old girl weighing 46 kg came hospital with complaint 12 days-menstrual bleeding. The patient is weak, pale. Eyes, ENT, heart, lungs, abdomen: within normal limits, no petechiae. Laboratorium: Hemoglobin (Hb) 4.6 g/dL, leukocytes 12,930/uL, platel...

Tiazofurin (2-beta-D-ribofuranosylthiazole-4-carboxamide, NSC 286193), a selective inhibitor of the activity of IMP dehydrogenase (EC 1.1.1.205), the rate-limiting enzyme of de novo GTP biosynthesis, provided in end stage leukemic patients a rapid decrease of IMP dehydrogenase activity and GTP concentration in the blast cells and a subsequent decline in blast cell count. Sixteen consecutive pat...

introduction the continuous and rapid growth of telecommunication industries, along with the common application of cell phones, hasraised debates on the associated risks for humanhealth due to exposure to radiofrequency fields, caused bycell phonesorother sources, and industrial and medical applications. accordingly, in this study, we aimed to investigate the effects of cell phone radiation on ...

In order to elucidate the question of whether the maturation defect in vivo in acute leukemia is due to environmental or cellular factors, we have cultured human leukemic cells in a nonleukemic milieu, i.e., diffusion chambers implanted into the abdominal cavity of normal and irradiated mice. For each harvest, the cell count was measured and differential counts and the number of peroxidase-posi...

Clinics and pathology Disease De novo ANLL; (one case of blast crisis CML). Phenotype / cell stem origin Mainly M2 or M4, but also M1, M5a, M5b, or M7 ANLL; may be preceded by MDS. Epidemiology About 30 reported cases, mainly found in young adults; children cases are described; median age is about 30 yrs; balanced sex ratio. Clinics Blood data: anemia, thrombocytopenia, mild hyperleucocytosis; ...
