(Universidad de Chile, 1989)
-
(Universidad de Chile, 1989)Se preparó un antígeno por extracción acuosalina en caliente y posterior precipitación por etanol, a partir de Brucella abortus 1119–3, el que se enfrentó por pruebas de inmunodifusión doble con sueros de bovinos infectados ...
-
(Universidad de Chile, 1989)
-
(1990)The leukemic cell line, WEHI-3B presents a latent collagenase-like activity which is activated after trypsin treatment. The enzymatic activity is not released from cells and is specific for the degradation of interstitial ...
-
(1990)A screening of antibodies against strain M‐41 and the Dutch variant strains D‐274 and D‐1466 of infectious bronchitis virus (IBV) using the haemagglutination inhibition test (HI) was carried out in Chile. The presence of ...
-
(1991)Evidence of absence of Trypanosoma cruzi kinetoplast DNA methylation by restriction endonuclease analysis. International Journal for Parasitology bd21: 863-866. Eight kinetoplast DNA samples from very different T. cruzi ...
-
(1991)In order to investigate growth following early severe malnutrition, two groups of 40 children and their mothers were studied, one of patients recovered from early protein energy malnutrition (PEM) at a closed center for ...
-
(1991)To investigate growth following a period of severe malnutrition in early life, we have studied longitudinally 2 groups of children and their mothers: the first one who had suffered protein energy malnutrition early in life ...
-
(BLACKWELL SCIENCE LTD, 1991-12)
-
(1992)A column (CarboPac PA1, Dionex) containing an anion-exchange pellicular resin was used for the separation of phosphoryl-hexoses derived from labeled glucose microinjected into individual frog oocytes or from cultures of ...
-
(1993)Pure 125I-radiolabeled chicken IgG was inoculated intravenously into 2-week old chickens. Radioactivity in lachrymal fluid samples was first detected 10 minutes postinoculation (PI). Radioactivity levels declined up to day ...
-
(1993)DNA synthesis in epimastigote forms of Trypanosoma cruzi was studied autoradiographically by incorporation of [3H]thymidine in the nuclear and kinetoplast DNA. Both DNA were heavily labelled. Three eukaryotic DNA polymerase ...
-
(1994)A rapid, sensitive and highly specific detection method for infectious pancreatic neerosis virus (IPNV), based on reverse transcription (RT) polymerase chain reaction (PCR) has been developed. The specificity of the assay ...
-
(1994)Since circulating antibody titres against infectious bronchitis virus (IBV) often correlate poorly with protection against re‐infection, the lachrymal specific IgA level of IBV vaccinated chickens was evaluated as an ...
-
(1994)Alpaca play a primary role in the Andean peasant economy. Major constraints to productivity include lack of knowledge of relations between reproduction and nutrition and of the potential of alpaca outside their normal ...
-
(1994)An ELISA to detect circulating antibodies against K99 pili, a major attachment factor to intestinal epithelial cells of Escherichia coli in calves, was performed. Two methods of K99 pili purification were attempted. Best ...
-
(Elsevier, 1994)Lachrymal fluid specific IgG and IgA were detected by ELISA in chickens with specific maternal antibodies and in chickens free of antibodies (SPF), after vaccination at 1 day of age with the H-120 vaccine strain of infectious ...
-
(1994)Broiler and layer chicken sera obtained from four different farms in Chile were tested by indirect immunoperoxidase assay for the presence or absence of antibodies against chicken anemia virus (CAV). Tests were conducted ...
-
(Elsevier GmbH, 1995)Multipotential hemopoietic progenitor cells (FDCP-mix) proliferate in culture medium supplemented with horse serum. When transferred to a medium without serum, cells do not proliferate and enter a quiescent state. Both ...
-
(1995)A molecular characterization of tubulin and microtubule‐associated proteins (MAPs) along with their intracellular pool distributions in both unfertilized and fertilized oocytes of the trout Oncorhynchus mykiss was carried ...
