Immune Tolerance Induction in Hemophilia A: A Review
2003
In this article, a comparative analysis of the data stemming from the studies conducted in the field of immune tolerance treatment (ITT) of hemophilia A was attempted. Comparisons are difficult because previous studies differ in many respects, including the dosage of factor (F) VIII, the number of FVIII administrations per day, the association with immunosuppressive drugs (prednisone, cyclophosphamide), and, most importantly, the definition of success in terms of the reacquisition of tolerance. However, a number of variables consistently influenced outcome: the inhibitor titer, either the maximum one or the one assayed before immune tolerance (IT) start and age. As to the FVIII dose, result…
Modulation of oestrogen excretion profiles by adjuvant chemotherapy in pre- and postmenopausal breast cancer.
1985
Modulation of steroid status by conventional chemotherapy was studied in 31 breast cancer patients receiving CMF and in 31 age-matched breast cancer patients without any therapy, taken as controls. This was achieved through the study of oestrogen excretion profiles using previously identified parameters and referring not only to classical but also to the “other”, namely catechol and unusual, oestrogen metabolites. After CMF treatment the premenopausal patients exhibit a modified excretion pattern, mainly concerning a marked and significant reduction of classical oestrogens, as shown by pattern indices. Because there is evidence that oestriol metabolism is not markedly affected by CMF treatm…
Alemtuzumab (Campath-1H) and CHOP chemotherapy as first-line treatment of peripheral T-cell lymphoma: results of a GITIL (Gruppo Italiano Terapie Inn…
2007
To evaluate in a prospective multicenter trial the feasibility and clinical efficacy of the combination of alemtuzumab (Campath-1H) with the cyclophosphamide/doxorubicin/vincristine/prednisone (CHOP) regimen (CHOP-C) as the primary treatment for patients with peripheral T-cell lymphoma (PTCL), between January 2003 and December 2005, 24 consecutive patients with PTCL entered the study and received 8 CHOP courses. Alemtuzumab was added at 30 mg subcutaneously at day −1 initially to the first 4 courses (4 patients), and then to all 8 courses (20 patients). Complete remission (CR) was achieved in 17 (71%) patients, 1 had partial remission, and 6 had stable/progressive disease. At a median follo…
Does self‐compassion help to deal with dietary lapses among overweight and obese adults who pursue weight‐loss goals?
2021
Objectives Self-compassion can facilitate self-improvement motivation. We examined the effects of self-compassion in response to dietary lapses on outcomes relevant to weight-loss strivings using a longitudinal design. The indirect effects of self-compassion via guilt and shame were also explored. Design An Ecological Momentary Assessment methodology was employed with a sample of adults who were overweight or obese attempting to lose weight via dietary restriction (N = 56; Mage = 34.88; SD = 13.93; MBMI = 32.50; SD = 6.88) and who responded to brief surveys sent to their mobile phones twice daily for two weeks. Methods Dietary temptations and lapses were assessed at each diary entry, and se…
hs-CRP Predicts Improvement in Depression in Patients With Type 1 Diabetes and Major Depression Undergoing Depression Treatment: Results From the Dia…
2016
hs-CRP is elevated in depression (1), but evidence on decreases of hs-CRP during depression treatment or the role of hs-CRP in the prediction of response to depression treatment is still controversial (2,3). To date, no study has examined this association in patients with diabetes. As elevated hs-CRP increases the risk of diabetes complications in diabetes (4), we aimed to explore hs-CRP in patients with diabetes and major depression undergoing depression treatment based on the data of the Diabetes and Depression (DAD) study (5). Participants were randomized to 12 weeks (short-term phase) of diabetes-specific group cognitive behavioral therapy or sertraline treatment and followed up for 15 …
Cytogenetic effects of promutagens in genetically engineered V79 Chinese hamster cells expressing cytochromes P450.
1993
Abstract V79 Chinese hamster cell lines genetically engineered to express rat CYP2B1, CYP1A1, CYP1A2, and their parental cell lines V79-MZ, without acetyltransferase, and V79-NH, with acetyltransferase, were studied for chromosome aberrations and sister chromatid exchange induced by aflatoxin B 1 , cyclophosphamide, benzo[a]pyrene, 7,12-dimethylbenz[a]anthracene and dimethylnitrosamine. The parental V79 cell lines did not show clastogenic effects. Significant clastogenic effects were observed after an 18 h exposure to aflatoxin B 1 and cyclophosphamide in CYP2B1 expressing cells, to benzo[a]pyrene in CYP1A1 and CYP1A2 expressing cells, to 7,12-dimethylbenz[a]anthracene and dimethylnitrosami…
Characterization of an epithelial, nearly diploid liver cell strain, from Chinese hamster, able to activate promutagens
1987
Epithelial liver cells of the Chinese hamster (CHEL cells) were propagated in culture for 35 passages. At favourable cell densities, the population doubling time in normal medium, was 20 h. L-Tyrosine amino transferase activity was retained at a measurable level, but its enhancement by dexamethasone was detected solely in cells of early passages. Pyruvate kinase was strongly activated by fructose-1,6-biphosphate at low substrate concentrations. These enzymatic properties suggest that the CHEL cells are derived from a sub-population of parenchymal hepatocytes or from cells closely related to parenchymal hepatocytes. With a lag period of a few hours, CHEL cultures metabolized benzo[a]pyrene. …
Stable expression of rat cytochrome P-450IIB1 cDNA in Chinese hamster cells (V79) and metabolic activation of aflatoxin B1.
1988
V79 Chinese hamster fibroblasts are widely used for mutagenicity testing but have the serious limitation that they do not express cytochromes P-450, which are needed for the activation of many promutagens to mutagenic metabolites. A full-length cDNA clone encoding the monooxygenase cytochrome P-450IIB1 under control of the simian virus 40 early promoter was constructed and cointroduced with the selection marker neomycin phosphotransferase (conferring resistance to G418) into V79 Chinese hamster cells. G418-resistant cells were selected, established as cell lines, and tested for cytochrome P-450IIB1 expression and enzymatic activity. Two cell lines (SD1 and SD3) were found that stably produc…
Maintenance Operation on AGN-201 “COSTANZA” Nuclear Research Reactor of Palermo University
2015
During operations with AGN-201 “COSTANZA” nuclear research reactor of Palermo University a failure of a compensated boron-lined ionization chamber provided with a measurement channel was highlighted. A maintenance program aimed to verify the operative conditions of all measurement systems was then started. It was easy to identify as cause of the malfunction a seepage of water inside the container of a Westinghouse WL 6377 ion chamber due to a lack of watertight closure. This can be attributed to corrosion of the container due to parasitic currents circulating between the container, the chamber and the reactor tank that acts as electrical ground of the system. In this work we refer over main…
A rhamnose-binding lectin from sea bass (Dicentrarchus labrax) plasma agglutinates and opsonizes pathogenic bacteria
2014
Abstract The discovery of rhamnose-binding lectins (RBLs) in teleost fish eggs led to the identification of a novel lectin family characterized by a unique sequence motif and a structural fold, and initially proposed to modulate fertilization. Further studies of the RBL tissue localization and gene organization were also suggestive of role(s) in innate immunity. Here we describe the purification, and biochemical and functional characterization of a novel RBL (DlRBL) from sea bass (Dicentrarchus labrax) serum. The purified DlRBL had electrophoretic mobilities corresponding to 24 kDa and 100 kDa under reducing and non-reducing conditions, respectively, suggesting that in plasma the DlRBL is p…
