The effects of mononuclear cells from nontransfused and transfused dogs on the growth of erythroid colonies (EC) from DLA-identical littermates were studied. To this purpose, marrow samples were cultured both before and after one to three transfusions from the DLA-identical littermate. Mononuclear cells obtained before transfusions and cocultured with autologous marrow or marrow from DLAidentic...

Indigenous microflora community changes during six months of co-composting of activated sewage sludge and date palm waste was investigated using two different culture approaches. In order to evaluate the co-composting process evolution for mixture A and B, growth standard media (GSM) and Compost Time Extract Agar (CTEA) are used. Enumeration for indigenous flora abundance on GSM medium shows th...

In this study, the culturability of indoor and outdoor airborne fungi was determined through long-term sampling (24-h) using a Button Personal Inhalable Aerosol Sampler. The air samples were collected during three seasons in six Cincinnati area homes that were free from moisture damage or visible mold. Cultivation and total microscopic enumeration methods were employed for the sample analysis. ...

BACKGROUND The Dijon University Hospital in Dijon, France is involved in a large construction program with heavy truck traffic and a very dusty environment. This study aimed to assess the impact of outdoor hospital construction work on Aspergillus air contamination in the immediate environment of patients at high risk for aspergillosis in the presence of protective measures. METHODS Prospecti...

We investigated Staphylococcus aureus contamination of the hand rims and handles of wheelchairs for common use on hospital wards by wiping with gauze. Examination of the hand rims of a total of 20 wheelchairs revealed methicillin-sensitive S. aureus (MSSA) and/or methicillin-resistant S. aureus (MRSA) on 17 wheelchairs (85.0%), and MRSA on 11 (55.0%). The mean ± SD (range) density of MRSA conta...

The hallmark of chronic myeloid leukemia (CML) is the presence of the bcr-abl oncogene, which is associated with transforming ability and an intrinsic resistance to induction of apoptosis by genotoxic agents. Arachidonic acid (AA), a biologically active fatty acid, plays a crucial role as a mediator of signaling pathways involved in cell proliferation and survival. In this study, we investigate...

The requirement of c-Myb during erythropoiesis spurred an interest in identifying c-Myb target genes that are important for erythroid development. Here, we determined that the neuropeptide neuromedin U (NmU) is a c-Myb target gene. Silencing NmU, c-myb, or NmU's cognate receptor NMUR1 expression in human CD34(+) cells impaired burst-forming unit-erythroid (BFU-E) and colony-forming unit-erythro...
