(1992)Severe clotting defects represent the main contraindication to percutaneous liver biopsy. A transvenous liver puncture technique has been developed for patients suffering from blood coagulation disorders. This approach was ...
-
(1991)G proteins are heterotrimeric proteins involved in the transduction of a variety of external signals in all eukaryotic organisms. This review analyzes the molecular aspects of G protein structure and function. The cloning ...
-
(Oxford University Press, 1992)In this study, we have evaluated the relationship between the acrosome reaction-inducing activity of individual human follicular fluid samples and their steroid content. Eighteen samples of follicular fluid were obtained ...
-
(1992)Sertoli cells in culture produce two isoforms of proteoglycans which are found in the culture medium and associated with the cell membrane. The amount of both types of proteoglycans increased when Sertoli cells were plated ...
-
(Springer-Verlag, 1992)The pharmacokinetics of nifurtimox, a drug used in the treatment of Trypanosoma cruzi infections, has been studied in seven patients with chronic renal failure undergoing haemodialysis, and in seven healthy subjects. Each ...

(1992)This study has assessed the effect of zinc on human sperm motility and the acrosome reaction in vitro. Progressively motile human sperm were selected by swim‐up and by glass bead columns and then incubated in a medium in ...
-
(Kluwer Academic Publishers, 1992)The microtubule-associated protein Tau, a major component of brain microtubules, shares common repeated C-terminal sequences with the high molecular-weight protein MAP-2. It has been shown that tau peptides V187-G204 and ...
-
(1992)Polylysine, polyornithine and, to a lesser extent, polyarginine were found to stimulate the GTPase activity of the purified recombinant α subunit of the human Gi-3 transducing protein αi-3. Optimal stimulation of 4- to ...

(1992)Sealed right-side-out reticulocyte ghosts transported and accumulated iron offered as 59Fe2+-ascorbate (K(m) = 1.1 μM). The uptake of iron by ghosts presented the characteristics of a transporter-mediated process: it ...
-
(1992)Acetaldehyde (AcH) administered intravenously or into the right ventricle induces reflex bradycardia, hypotension, and apnea in the rat. The efferent pathway for this reflex is vagal and probably secondary to pulmonary J ...
-
(1992)A clinicoepidemiological study was undertaken to determine if enterohemorrhagic Escherichia coli (EHEC) was associated with hemolytic- uremic syndrome (HUS) in children in Santiago, Valdivia, and Temuco, Chile. Prospective ...
-
(1992)The protein quality of Lupinus albus cv Multolupa was evaluated in young adult males using the nitrogen balance technique at graded levels of N intake, and compared with egg protein. Lupin protein was consumed at levels ...
-
(1992)Trypanosoma cruzi presents six histones electrophoretically resolved in three gel systems. Indirect evidence shows that one of these histones, name, corresponds to H4 in other species. We present evidence that histones is ...
