(Blackwell Publishing Ltd, 2006)Nonlinear ion-acoustic like waves triggered by large-amplitude circularly polarized waves propagating in the direction of a proton beam are studied. The properties are strongly dependent on the nature of the large-amplitude ...
-
(Blackwell Publishing Ltd, 2006)It is shown that nonlinear left-hand polarized waves can either stabilize or destabilize linear right-hand polarized instabilities triggered by an alpha particle beam in a magnetized electron proton plasma. For differential ...

(2009)Background: There is limited information regarding the effects of IGF-I and/or IGFBP-3 on circulating leptin concentrations. Aim: To determine the effects of IGF-I on leptin and insulin concentrations, we examined leptin ...
-
(1971)A new approach to the bound-state problem in the frame of quantum electrodynamics is proposed, with special emphasis on the electron-proton bound states. It is an alternative approach to the usual one, which is based on ...
-
(Editorial Triacastela, 2006)Following the tradition of researchers of the phenomenological- anthropological school such as Straus, von Gebsattel, Tellenbach and Blankenburg, the author attempts to approach the obsessive-compulsive disorder from a ...
-
(1972)Our Chilean colleagues, keenly sensitive to the prevalence of gastric cancer in that country, describe a patient with an antral ulcer which appeared to be highly suspicious of an early gastric carcinoma. Such was not the ...
-
(2002)Thyroid hormone-induced calorigenesis contributes to liver oxidative stress and promotes an increased respiratory burst activity in Kupffer cells, which could conceivably increase the expression of redox-sensitive genes, ...

MHC class II-deficient tumor cell lines with a defective expression of the class II transactivator (Oxford University Press, 2002)MHC class II expression defects have been evidenced in several human tumor cell lines originating from lung cancers or retinoblastoma. Accordingly, the mouse adenocarcinoma and fibrosarcoma cell lines, RAG and L(tk-), do ...

(2001)The human leukocyte antigen (HLA) system plays a crucial role in the autoimmune process leading to childhood diabetes. The purpose of this study was to evaluate the association between type 1 diabetes and the polymorphism ...

(1987)Mutagenesis of Clostridium butyricum ATCC 19398 was best accomplished by u.v. irradiation (254 nm) and methyl methane sulphonate. Nitrosoguanidine was only slightly mutagenic for this organism. Procedures are described ...

(Society for General Microbiology, 2002)Analysis of the 16S rDNAs obtained from cultures of single colonies of either type collection strains or environmental strains of the genus Vibrio revealed the presence of polymorphism in every one of the strains examined. ...

(2001)It is shown that damping effects can destabilize regions that are stable under non-dissipative fluid theory. Damping effects on the ion-acoustic modes are simulated by a collisional-like term in the longitudinal component ...

(American Ornithologist Society, 2001)In vertebrates, enzymatic activity levels in the small intestine are correlated with dietary composition. We examined enzymatic activity levels in juvenile specimens of two flamingo species, Phoenicoparrus andinus and ...
