The nuclear factor (NF)-kappaB system is a promising anticancer target due to its role in oncogenesis and chemoresistance in preclinical models. To provide evidence in a clinical setting on the role of NF-kappaB in breast cancer, we aimed to study the value of basal NF-kappaB/p65 in predicting resistance to neoadjuvant chemotherapy, and to characterise the(More)
Nasopharyngeal aspirates were obtained on admission from 614 patients younger than 2 years of age who were hospitalized in a ward for acute respiratory infections from June 1988 through October, 1989, in Santiago, Chile. Patients in two rooms were followed during the cold seasons by sampling aspirates every other day during the child's entire hospital stay.(More)
Our goal was to analyze the results of a multicity program offering rapid HIV testing in a mobile unit in central locations. Between October 2006 and December 2007, 7138 persons were tested, providing a finger-prick blood sample and filling out a brief questionnaire while waiting for the results of the Determine((R)) test. Seventy people were classified as(More)
Inhalation anesthesia with halothane, inhibiting hypoxic pulmonary vasoconstriction, causes an increase in intrapulmonary shunt development as well as an increase of alveolar-arterial oxygen tension difference. In contrast, total intravenous anesthesia with propofol, as with other intravenous anesthetics, should not alter pulmonary gas exchange. The present(More)
Five in a series of ten patients with laparoscopically demonstrated salpingitis had cultures positive for Chlamydia trachomatis obtained from tubal and peritoneal surfaces. Spermatozoa were observed in the peritoneal fluid of three of these patients, and two had cultures positive for C trachomatis. C trachomatis was attached to spermatozoa recovered from(More)
We investigated the presence of Chlamydia trachomatis in fallopian tubes of patients undergoing Pomeroy tubal ligation in the immediate postpartum period with culture on cycloheximide-pretreated McCoy cells and with immunofluorescence staining. Two of 20 women were culture positive in both tubes, representing 10% culture positivity. Both patients were(More)
In a study designed to evaluate the genetic variability of adenovirus strains associated with infantile cases of respiratory disease requiring hospitalization, a collection of 136 adenovirus isolates obtained in the Roberto del Rio Children's Hospital of Santiago, Chile between June 1988 and November 1990 was studied by restriction enzyme analysis.(More)
In Spain, approximately 10 years passed between the time when human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) harm-reduction programs should have been developed with sufficient coverage to have an optimum impact on public health (before the HIV/AIDS epidemic's explosion in 1984) and the date of their actual implementation. This(More)
We have investigated the prevalence of antibodies against Toxoplasma gondii, Trypanosoma cruzzi, Hepatitis B virus, cytomegalovirus, rubella virus, and human immunodeficiency virus in 139 adolescent pregnant women and in their high risk newborn children. The methods employed were the Sabin and Feldman reaction, complement fixation reaction, ELISA, and(More)
OBJECTIVE To estimate the percentage of men who have paid for heterosexual sex in Spain and the percentage who used condoms. To identify the main factors associated with these behaviours and to describe opinions about condoms.
