1. Outpatient haploidentical hematopoietic stem cell transplant using post-transplant cyclophosphamide and incidence of hemorrhagic cystitis
Abstract Introduction Hemorrhagic cystitis (HC) is a common complication of haploidentical hematopoietic stem cell transplantation (haplo-HSCT), characterized by irritative symptoms of the urinary tract and a higher morbidity and mortality rate. The worldwide incidence is reported between 10% and 70%. The use of alkylating agents and BK viral infection are

3. Pharmacovigilance of patients with multiple myeloma being treated with bortezomib and/or thalidomide
In order to evaluate the main adverse effects of drug protocols using bortezomib and/or thalidomide for the treatment of multiple myeloma, we conducted a prospective study. Data were collected through interviews, clinical observation, and from hospital records. A total of 59 patients were included. There was a predominance of females, 36 (61%) vs 23 (39%) ma

4. Male fertility potential alteration in rheumatic diseases: a systematic review
ABSTRACT Background Improved targeted therapies for rheumatic diseases were developed recently resulting in a better prognosis for affected patients. Nowadays, patients are living longer and with improved quality of life, including fertility potential. These patients are affected by impaired reproductive function and the causes are often multifactorial rel

5. Effects of artichoke (Cynara scolymus) leaf and bloom head extracts on chemically induced DNA lesions in Drosophila melanogaster
The genotoxicity of bloom head (BHE) and leaf (LE) extracts from artichoke (Cynara scolymus L.), and their ability to modulate the mutagenicity and recombinogenicity of two alkylating agents (ethyl methanesulfonate - EMS and mitomycin C - MMC) and the intercalating agent bleomycin (BLM), were examined using the somatic mutation and recombination test (SMART)

6. Synthesis and characterization of methylcellulose from cellulose extracted from mango seeds for use as a mortar additive
Methylcellulose was produced from the fibers of Mangifera indica L. Ubá mango seeds. MCD and MCI methylcellulose samples were made by heterogeneous methylation, using dimethyl sulfate and iodomethane as alkylating agents, respectively. The materials produced were characterized for their thermal properties (DSC and TGA), crystallinity (XRD) and Degree of Sub

7. Karyotypic and fluorescent in-situ hybridization study of the centromere of chromosome 7 in secondary myeloid neoplasms
BACKGROUND: Secondary myeloid neoplasms comprise a group of secondary diseases following exposure to myelotoxic agents or due to congenital diseases. The improvement of anticancer agents and immunosuppressive drugs seem to be associated with an increased incidence of secondary myeloid neoplasms. Karyotyping of bone marrow is essential for diagnosis and progn

8. Synthesis of unnatural α-amino acids, precursors of the inhibitors of thrombin - via Phase Transfer Catalysis (PTC) / Síntese de α-aminoácidos não naturais -precursores de agentes inibidores da trombina - via Catálise de Transferência de Fase (CTF)
Seven novel a-aminoacids precursors were prepared by the alkylation reaction of ethyl acetamidocyanoacetate 112 using bromohexane, benzyl chloride, allyl bromide, 9-(chloro-methyl)antracene, 3-nitrobenzyl bromide, 4-nitrobenzyl bromide, 4-metoxibenzyl bromide and 2-methyl-naphtyl bromide as alkylating agents via Phase Transfer Catalysis (PTC). These reaction

9. Assessment of cellular responses mediated by temozolomide combined with metoxiamina, an inhibitor of DNA repair, in glioblastoma cell lines. / Avaliação da resposta celular mediada pelo quimioterápico temozolomida associada ao inibidor do reparo do DNA metoxiamina em linhagens de glioblastoma.
Gliomas represent more than 70% of primary brain tumors. Even following an aggressive therapies, the mean survival rate of patients with these tumors is less than one year after diagnosis. Chemotherapy based on alkyklating agents, such as temozolomide (TMZ) has been reported to increase the survival rate. N7-metyl-G and N3-metyl-A adducts comprise more than

10. Collection of peripheral blood progenitor cell after administration of cyclophosphamide and granulocyte-colony stimulating factor (GCSF): an analysis of 307 patients / Coleta de células progenitoras hematopoéticas de sangue periférico após administração de ciclofosfamida e fator estimulador de colônias de granulócitos (G-CSF): uma análise de 307 pacientes
Inadequate stem cells mobilization is seen in 10-30% of patients undergoing autotransplantation for hematologic malignancies. Factors affecting peripheral blood progenitor cell (PBSC) mobilization have not been clearly established. We retrospectively reviewed the data of patients treated by autologous bone marrow transplantation (BMT) with the aim to identif

11. Gemcitabina e ifosfamida no tratamento do linfoma de Hodgkin refratário ou recidivado após múltiplas terapias
Patients with Hodgkin's lymphoma relapsed after or refractory to multiple therapies (rHL) have a dismal prognosis. Monotherapy with gemcitabine can promote an overall response rate of about 40% in these patients and its association with alkylating agents can provide better results. We retrospectively evaluated 17 rHL cases. All were treated with the combinat

12. Caracterização espectroscopica de catalisador a base de renio suportado em silica-alumina, modificado com oxido de boro e agentes alquilantes / Spectroscopic characterization of a rhenium oxide catalyst supported on borated silica-alumina and modified whit alkylating agents
Os catalisadores heterogêneos à base de rênio constituem-se importantes sistemas na metátese de ésteres insaturados provenientes dos óleos vegetais. No entanto, os sistemas heterogêneos à base de rênio são ativos na metátese de olefinas funcionalizadas somente se forem combinados com um promotor do tipo SnR4 ou PbR4. Acredita-se que o promotor tem
