BACKGROUND Grass pollens are major triggers of allergic rhinitis and asthma, but the immunological relationships between pollen allergens of the subtropical Bahia grass, Paspalum notatum, and temperate grasses are unresolved. OBJECTIVE To assess serum IgE cross-reactivity between subtropical P. notatum and temperate Lolium perenne (Ryegrass) pollen(More)
BACKGROUND Hepatitis B virus (HBV) reactivation in patients positive for antibody to HB core antigen (anti-HBc), negative for HB surface antigen (HBsAg) and HBV-DNA (potential occult HBV carriers), treated with anti-tumor necrosis factor (TNF)α, is a debated question. The aim of the study was to evaluate the safety of anti-TNFα therapy in anti-HBc(More)
This work addresses the synthesis and biological evaluation of glycosyl diketopiperazines (DKPs) cyclo[Asp-(αGalNAc)Ser] 3 and cyclo[Asp-(αGalNAc)Thr] 4 for the development of novel anti-trypanosomal agents and Trypanosoma cruzi trans-sialidase (TcTS) inhibitors. The target compounds were synthetized by coupling reactions between glycosyl amino acids(More)
Human chorionic gonadotrophin (hCG), human menopausal gonadotrophins (hMG) and somatotrope hormone (STH) were used for three months to induce spermatogenesis in a patient with azoospermia following hypophysectomy for Cushing's syndrome. Azoospermia reappeared when testosterone was substituted for hCG, despite continued treatment with FSH and STH. In a(More)
A pregnancy obtained through in vitro fertilization in a case of male sterility due to oligospermia with high FSH is reported. After a review of controlled studies dealing with classical andrological treatments (repair of varicocele, treatment of prostatitis and immunological sterility), the place of in vitro fertilization is evaluated in relation to(More)
