- ItemBIOSYNTHESIS OF THE NEUROFILAMENT HEAVY SUBUNIT IN XENOPUS OOCYTES MICROINJECTED WITH RAT-BRAIN POLY(A)+ RNA(1987) CROSS, D; ALLENDE, ML; KRAUSS, RY; FUENTES, ME; KALTWASSER, G; ALVAREZ, J; INESTROSA, NCIn order to study the expression of the major subunit of neurofilaments (NFs), rat brain poly(A)+ RNA was purified by three different procedures and was injected in Xenopus laevis oocytes. This system was able to translate efficiently the 200 kDa NF subunit as shown by a dot-blot immunoassay and by immunoprecipitation of labeled NF polypeptides.
- ItemENZYMATIC DNA AMPLIFICATION (PCR) IN THE DIAGNOSIS OF EXTRAPULMONARY MYCOBACTERIUM-TUBERCULOSIS INFECTION(ACADEMIC PRESS LTD, 1993) KALTWASSER, G; GARCIA, S; SALINAS, AM; MONTIEL, F
- ItemINVITRO SUSCEPTIBILITY TO 10 ANTIBIOTICS OF METHICILLIN-RESISTANT (MRSA) STAPHYLOCOCCUS-AUREUS IN CHILE(1988) MONTIEL, F; KALTWASSER, G; VALDIVIESO, C; LAM, MThe in vitro activity of 10 antibiotics was determined for 231 strains of methicillin resistant (MRSA) Staphylococcus aureus. Oxacillin was a very good antibiotic to determine methicillin-resistance. Its agreement with methicillin-resistance was in all the strains tested. On the contrary, the correlation with nafcillin was established only in 95% of the strains tested. Cloxacillin and flucloxacillin are not good methicillin-resistance indicators. The strains tested against macrolides, such as erythromycin, and lincosamides, such as lincomycin and clindamycin presented a susceptibility of 68, 78, and 80%, respectively. All tested strains were susceptible to vancomycin.
