Caspase-3 is activated during both terminal differentiation and erythropoietin-starvation-induced apoptosis of human erythroid precursors. The transcription factor GATA-1, which performs an essential function in erythroid differentiation by positively regulating promoters of erythroid and anti-apoptotic genes, is cleaved by caspases in erythroid precursors(More)
Metastatic lymph nodes (LNs) are the major prognostic factor in resected non small cell lung carcinoma (NSCLC). However, almost 50% of pN0 patients relapse, suggesting metastatic cells undetected by current staging procedures. A combination of markers [cytokeratins 19 and 7 (CK19, CK7) and mucin type 1 (MUC1) mRNAs] was therefore evaluated by real-time(More)
The aim of this study was to assess test-retest reliability of a common method for quantifying taste perception and its association with gustatory responses and individual risk for obesity and related health conditions. Forty-six healthy adults rated 20 mixtures comprised of 5 dairy beverages varied in fat content and mixed with sugar concentrations of 0%,(More)
Differentiating agents have been proposed to overcome the impaired cellular differentiation in acute myeloid leukemia (AML). However, only the combinations of all-trans retinoic acid or arsenic trioxide with chemotherapy have been successful, and only in treating acute promyelocytic leukemia (also called AML3). We show that iron homeostasis is an effective(More)
Ochratoxin A is a carcinogen and nephrotoxin which can enter the food chain resulting in human exposure. As pig herds are exposed to ochratoxin A through their feed, their kidneys, livers and pork meat are considered as a possible route of exposure for humans. France, an important producer of pork and pork products, set up a national monitoring programme(More)
BACKGROUND Acupuncture according to the Chinese syndrome is often used in patients with postmenopausal complaints. Often these patients have an increased blood pressure. As experienced therapists report that acupuncture is efficient also in hypertension, our aim was to investigate whether the acupuncture used for the treatment of postmenopausal syndrome(More)
Socioeconomic disadvantage has been linked to elevated blood pressure (BP), and the purpose of this study was to assess whether interpersonal social supports buffer these adverse relations in African-American adults. In three communities matched demographically, a subsample of participants (N = 204) of the Positive Action for Today’s Health trial provided(More)
Estradiol is a steroid hormone secreted by endocrine glands (ovary, testis) [3]. The variation of estradiol levels in blood or urine may be associated with many pathologies such as hormone-dependent cancers and diseases of sexual behaviour [5]. Measurements of the concentration of estradiol in blood or urine is of great importance both for clinical(More)
Mantle cell lymphoma (MCL) is one of the most frequent of the newly recognized non-Hodgkin's lymphomas. The major problem of MCL therapy is the occurrence of relapse and subsequent resistance to chemotherapy and immunotherapy in virtually all cases. Here, we show that one injection of anti-human transferrin receptor (TfR) monoclonal antibody A24 totally(More)
T follicular helper (Tfh) cells play an essential role in the development of antigen-specific B cell immunity. Tfh cells regulate the differentiation and survival of activated B cells outside and inside germinal centers (GC) of secondary lymphoid organs. They act through cognate contacts with antigen-presenting B cells, but there is no current marker to(More)
