Circular Natural Geoforms, Sierras Pampeanas, Argentina  [PDF]
Adolfo Antonio Gutiérrez, Ricardo Mon, Clara Eugenia Cisterna
Open Journal of Geology (OJG) , 2017, DOI: 10.4236/ojg.2017.79086
Abstract: We describe two circular morphological features representing depressed areas. This preliminary work is based on visual interpretations from Landsat ETM satellite images and SRTM Radar scans. The two geoforms are located at the north of the Sierras Pampeanas in Argentina. The La Ciénaga circular indentation is 15 km in diameter and Las Cejas is 34 km in diameter. Until now rings of these characteristics, magnitudes and diameters are unknown and unheard of in Argentina.

Rosa Cangemi de Gutiérrez, Viviana Santos, Marta Cecilia, Clara Silva, María Nader-Macías
Annals of Clinical Microbiology and Antimicrobials , 2004, DOI: 10.1186/1476-0711-3-23
Abstract: Respiratory tract infections are commonly caused by Streptococcus pneumoniae. Extensive antibiotic use for these infections as well as misuse for viral respiratory infections has led to increased penicillin resistance amongst the streptococci [1-6]. Even though there is a very broad description of the pattern of sensibility to antibiotics of this pathogen and other potentially pathogenic microorganisms, there are a small number of publications referred to the lactobacilli sensitivity to these types of compounds [7-10]. The antibiotic treatment modifies the stability of the normal or indigenous microbiota, producing the dominance of certain microorganisms able sometimes to produce a secondary infection [11]. There are a lot of approaches trying to restore the normal microbiota, or to avoid modifications of the different ecosystems to prevent infections, both for human and animal application. One of the main research areas related to the restoration of the indigenous flora is the application of probiotic microorganisms [12-14].Lactic Acid Bacteria (LAB) has been widely used to restore the ecologic equilibrium of different areas [12-14], mainly for the gastrointestinal tract. In the last decade, there is a lot of other research areas referred to the potential application of probiotics in the respiratory tract mainly as vaccine vectors [15-17]. They could be applied for the protection against pathogenic microorganisms as S. pneumoniae which is a frequent nasopharynx colonizer. In previous papers, the isolation and identification of the microorganisms of the normal microbiota of the respiratory tract of mice was reported by our research group. Also, the evolution from the moment they were born up to two months age was published [18]. In the isolated microorganisms, the probiotic or beneficial characteristics were studied, selecting some strains of the genus Lactobacillus that shared some properties [19]. From them, a strain of Lactobacillus fermentum was selected by the

Revista chilena de obstetricia y ginecología , 2010, DOI: 10.4067/S0717-75262010000200010
Abstract: background: the incidence of ectopic pregnancy is 20 per 1,000 pregnancies. the cornual ectopic pregnancy is found in 2-4%. hydatidiform moles occur in 1 per 1000 pregnancies in usa and 1 per 500 in mexico. thus, the incidence of the two occurring together is very rare. only 40 cases have been reported in the medical literature, the incidence estimate is 0.04%. clinic case: we analyzed a 30 year old woman patient case, gravida 1, with 8 weeks? gestation by last menstrual period, came at the hospital universitario ?dr. josé eleuterio gonzález?, monterrey, nuevo león, with complaints of nausea and vomiting for 1 day and abdominal pain, and transvaginal bleeding. a cualitative pregnancy test was positive. physical examination revealed diffuse abdominal tenderness and peritoneal signs. the transvaginal ultrasonography showed a multicystic echogenic mass within the uterus near cornual region consistent with a molar pregnancy. a cornual resection was performed followed by dilation and curettage. pathologic diagnosis was confrmed. the monitoring of ?-hgc titers was negative 7 weeks after surgery.
Efecto tóxico de Verbena officinalis (familia verbenaceae) en Sitophilus granarius (coleoptera: curculionidae)
Arango Gutiérrez,Gloria Patricia; Vásquez Villegas,María Clara;
Revista Lasallista de Investigación , 2008,
Abstract: introduction. sitophilus granarius, or maize beetle, is considered as one of the most important plagues of stored products. objective. to evaluate the effect of verbena officinalis in the sitophilus granarius control in stored corn. materials and methods. two presentations of verbena verbena officinalis were avaluated in the laboratory for the control of sithophilus granarius in stored corn, with concentrations in powder of 0,4 g, 0,8 g, and 1,6 g per every 10 g of corn and manure of 3, 6 and 9 ml per every 10 g of variable maize was the mortality rate of the imagos. the experimental design was done at random, the treatments had four repetitions. results. the highest mortality rate was obtained in powder in concentration of 1,6 gr with a mortality rate of 50%. in the variance analysis made, the kinds of presentation were meaningless and the concentrations used in the verbena extract were too low to generate a higher mortality in sitophilus. conclusion. secondary metabolites have a toxic activity against insects, interfering in their development or their behavior, and thus contributing to plague control.

Clara del Carmen Flores Acosta,Oralia Barboza Quintana,Oscar Vidal Gutiérrez,Felipe Morales Martínez
Revista Chilena de Obstetricia y Ginecología , 2010,
Abstract: Antecedentes: La incidencia de embarazo ectópico es 20/1000 embarazos y en la región cornual se presentan en el 2-4%. La mola hidatiforme ocurre en 1/1000 embarazos en EEUU y 1/500 en México. La presentación simultánea es muy rara. Se han descrito solamente 40 casos en la literatura médica, con una incidencia estimada de 0,04% de localización cornual. Caso clínico: Primigesta de 30 a os, que cursando un embarazo de 8 semanas, acude de urgencia por presentar náuseas y vómitos de 1 día de evolución, con dolor abdominal y sangrado vaginal. Prueba de embarazo positiva. A la exploración física presenta dolor abdominal difuso y signos de irritación peritoneal. El ultrasonido transvaginal mostró imagen ecogénica multiquística intrauterina cercana a la región cornual, por lo que se sospecha embarazo molar. En la laparotomía exploradora se realizó resección cornual y posteriormente dilatación y curetaje de la cavidad uterina. La anatomía patológica confrmó el diagnóstico. Negativizó -hGC a las 7 semanas después de la cirugía. Background: The incidence of ectopic pregnancy is 20 per 1,000 pregnancies. The cornual ectopic pregnancy is found in 2-4%. Hydatidiform moles occur in 1 per 1000 pregnancies in USA and 1 per 500 in Mexico. Thus, the incidence of the two occurring together is very rare. Only 40 cases have been reported in the medical literature, the incidence estimate is 0.04%. Clinic case: We analyzed a 30 year old woman patient case, gravida 1, with 8 weeks’ gestation by last menstrual period, came at the Hospital Universitario “Dr. José Eleuterio González”, Monterrey, Nuevo León, with complaints of nausea and vomiting for 1 day and abdominal pain, and transvaginal bleeding. A cualitative pregnancy test was positive. Physical examination revealed diffuse abdominal tenderness and peritoneal signs. The transvaginal ultrasonography showed a multicystic echogenic mass within the uterus near cornual region consistent with a molar pregnancy. A cornual resection was performed followed by dilation and curettage. Pathologic diagnosis was confrmed. The monitoring of -hGC titers was negative 7 weeks after surgery.

Clara Morales Pérez,Humberto Guanche Garcell,Francisco Gutiérrez García,Carlos Martínez Quesada
Revista Cubana de Enfermer?-a , 2004,
Abstract: Se estudiaron 129 pacientes egresados de la unidad de cuidados intermedios del hospital "Joaquín Albarrán" durante el primer trimestre de 2002. Se registró la edad, sexo, estadía hospitalaria, procederes de riesgo realizados, complicación con infecciones nosocomiales, la localización de las mismas y costo por estadía. Se utilizaron las pruebas estadísticas siguientes: t de homogeneidad y de Wilcoxon y en una segunda etapa, regresión lineal múltiple. Sin controlar la edad, la estadía global en la unidad y otras salas hospitalarias, resultó superior en los pacientes con infección nosocomial. Igual resultado se obtuvo para los costos por estadía y utilización de antimicrobianos (p = 0,00). Al ajustarse por edad, los resultados del estudio no cambiaron lo que sugirió que la infección nosocomial es un predictor independiente del incremento de los costos por estadía y utilización de antimicrobianos.
