(1979)The relationship between the time in the menstrual cycle when a TCu-200 or Cu-7-200 is inserted and subsequent IUD-related events was evaluated. For women who had either TCus or Cu-7s inserted, the pregnancy, expulsion and ...
-
(2009)The aims of these recommendations were to develop clinical guidelines for evaluation and mana-gement of patients with differentiated thyroid cancer applicable to Latin American countries. The panel was composed by 13 members ...
-
(Blackwell Publishing Ltd, 2009)It is well known that nonlinear electrostatic instabilities can be triggered in a plasma with streaming ion species in the presence of finite-amplitude Alfvén cyclotron waves. The instability occurs when the phase velocity ...
-
(2009)Background. Thermotolerant Campylobacter is among the more prevalent bacterial pathogens that cause foodborne diseases. This study aimed at evaluating the occurrence of thermotolerant Campylobacter contamination in chicken ...
-
(Kluwer Academic Publishers-Plenum Publishers, 1978)The genetics of the digging behavior of Drosophila melanogaster larvae was studied through selective breeding. Selection for low digging activity was successful, but selection for high digging activity was not. Selection ...
-
(2009)Thyroid Hormone Receptor β (THRB) defects, typically transmitted as autosomal dominant traits, cause Resistance to Thyroid Hormone (RTH). We analyzed the THRB gene in thirteen South American patients with clinical evidence ...
-
(2009)Antiviral antibody production during respiratory syncytial virus (RSV) infection in infants is poorly understood. Tocharacterize localBlymphocyte responses, lung tissue and secretions from infants withRSVbronchiolitis were ...
-
(2008)We present a new map of the spatial variations in effective elastic thickness, Te, along the Andes estimated using Bouguer coherence. The Te variations reflect interactions between subducting slab and preexisting terrane ...
-
(2009)Little evidence exists on the possible adverse effects of styrene on the central part of the auditory system. The present investigation aimed to study the possible association between styrene exposure and temporal processing ...
-
(2007)Recently, we reported that oxidative stress due to 3,3′,5- triiodothyronine (T3)-induced calorigenesis up-regulates the hepatic expression of mediators promoting cell protection. In this study, T3 administration in rats ...
-
(2009)Background. Interfant-99 was an international collaborative treatment protocol for infants with acute lymphoblastic leukemia (ALL). Procedure. We collected data on 103 infants at the time of their first treatment with ...
-
(John Wiley and Sons Ltd, 2009)Objective: To determine the prevalence rates of the different HPV types in cervical cancer lesions in Chile to facilitate the development of prophylactic human papillomavirus (HPV) vaccines effective for that country. ...
-
(1997)We study the modulational instability of an electron-positron plasma with relativistic temperatures and phonon damping. It is shown that when the phonon damping is O (1) or O (ε), a modulational instability appears even ...
-
(1997)We study the parametric decays of an electromagnetic wave propagating along an external magnetic field in an electron-positron plasma. We include weakly relativistic effects on the particle motions in the wave field, and ...
-
(1978)Two cases of gallbladder disease found in Chilean mummies are presented. The cholesterol gallstones in these cases produced in one individual a localized peritonitis and in the other a probable duct obstruction. No cases ...
-
(1977)The onset of acid and alkaline phosphatase activity is determined by means of Burstone's azo dye coupling methods in oocytes and embryos of the mouse, rat and hamster, and in mouse embryos cultured in vitro. Acid phosphatase ...
-
(Elsevier, 2009)The urine field osmolality in Zonotrichia capensis along a latitudinal gradient in rainfall and temperature in Chile was examined. We also investigated latitudinal variation in the renal traits that mediate how these birds ...
