Bone marrow-derived mesenchymal stromal cells (BM-MSCs) play a fundamental role in the BM microenvironment (BME) and abnormalities of these cells may contribute to acute myeloid leukemia (AML) pathogenesis. The aim of the study was to characterize the cytokine and gene expression profile, immunophenotype and cytogenetics of BM-MSCs from AML patients compared to normal BM-MSCs from healthy donor...

BACKGROUND Light chain amyloidosis (AL) is a rare deposition disease and is present in 10-15% of patients with myeloma (MM). In contrast to symptomatic AL in MM, presence of bone marrow (BM) amyloid deposits (AD) in MM is not connected to kidney damage. Renal AD but not BM-AD occur mostly in MM with lambda paraprotein (lambda MM). METHODS We investigated amyloid presence in BM clots taken at ...

The aim of the present study was to characterize the effects of BM 208 (N-[4-(5-chloro-2-methoxybenzamidoethyl)benzenesulfonyl]-N'-cyano- N"- cyclohexylguanidine) and BM 225 (1-[4-(5-chloro-2-methoxybenzamidoethyl)benzene sulfonamido]-1-cyclohexylamino-2-nitroethylene), two newly synthesized isosteres of glibenclamide, on ionic and secretory events in rat pancreatic islet cells. Both compounds ...

BACKGROUND The prognosis of breast cancer patients with brain metastasis (BM) is extremely poor, and the survival after development of BM is very short. We aimed to investigate clinicopathological factors related to significant effects on the prognosis after BM development. PATIENTS AND METHODS This is a retrospective study of 75 early breast cancer patients who received the standard of care ...

Characterization of the different lymphocyte populations in normal human bone marrow (BM) was attempted and compared to that in the peripheral blood (PB). B cells comprised 34% +/- 11% of lymphocytes in BM and 23% +/- 9% in PB. The majority of B cells carried IgM in BM and IgG in the PB. In the BM, cells carrying complement or Fc receptors were fewer than cells carrying Ig, but in the PB they w...

Business model (BM) innovation for sustainability is hampered by a lack of tools environmental assessment and guidance at the BM level. Conventional life cycle (LCA) neglects economic socio-technical mechanisms within BM, based on canvas (BMC) cannot provide recommendations substantiated data. Here, new method, BM-LCA, applied to case comparing selling renting jackets, using profit as basis com...

BACKGROUND The prognostic impact of the presence of differentiating neuroblasts in bone marrow (BM) remains unclear in BM metastatic neuroblastoma (NB). We aimed to identify the prognostic impact of differentiating neuroblasts in BM at diagnosis and after chemotherapy. METHODS A total of 51 patients diagnosed with BM metastatic NB at Asan Medical Center between January 1990 and July 2005 were...

PURPOSE Bone-marrow (BM)-derived hematopoietic precursor cells are thought to participate in the growth of blood vessels during postnatal vasculogenesis. In this investigation, multichannel laser scanning confocal microscopy and quantitative image analysis were used to study the fate of BM-derived hematopoietic precursor cells in corneal neovascularization. METHODS A BM-reconstituted mouse mo...

objective(s): nowadays much effort is being invested in order to diagnose the mechanisms involved in neural differentiation. by clarifying this, making desired neural cells in vitro and applying them into diverse neurological disorders suffered from neural cell malfunctions could be a feasible choice. thus, the present study assessed the capability of fetal brain extract (fbe) to induce rat bon...

background infertility is a serious social problem in advanced nations, with male factor in half of all cases of infertility. this study was conducted to determine the regenerative effect of bone marrow-derived stem cells in spermatogenesis of infertile hamster. methods twelve adult male hamsters were equally divided into azoospermic and control groups. busulfan was intraperitoneally used for i...
