Occurrence of Inoceramus in the South Atlantic and oxygen isotopic paleotemperatures in DSDP Hole 75-530A

Inoceramus occurs in every DSDP hole that penetrated Cretaceous sediments in the South Atlantic Ocean, and specimen occurrence has been mapped in detail for each core. Oxygen and carbon isotope measurements were completed on 18 Inoceramus specimens from Hole 530A. Textural evidence of diagenesis is accompanied by depletion in 18O. Paleotemperature results were obtained from 11 well-preserved specimens. Bottom water temperatures in the Angola Basin decreased from 23°C during the Coniacian to 13°C near the end of the Campanian.

An elevated systolic blood pressure response at 8 minutes in full contact exercise may identify hypertensive subjects

The aim of this study was to identify hypertension (HT) in karate competitors (KCs) in high intensity exercise. Values were compared with an exercise control group (EC). The 84 subjects were randomly divided into two groups: KC and EC. Resting blood pressure (BP) was measured the day before and immediately precompetition. A further three measurements were taken postexercise for all subjects at 1-, 2-, and 8- minute intervals. At rest, day one, mean BP of KC was 134/84 ± 3/2 mmHg vs. EC, 124/72 ± 1/2 mmHg and on day 2, was 141/79 ± 3/2 mmHg vs. EC, 125/72 ± 1/2 mmHg, respectively. Eight minutes postcompetition, BP of KCs was 140/77 ± 2/1 mmHg vs. EC 135/75 ± 2/1 mmHg. High blood pressure (HBP) was recorded in 60.5% of KCs on day 2, and essential HT that required medical therapy was subsequently diagnosed in 5% of KCs. Five percent of EC also had HBP, but subsequent medical examination reported normal values.

Toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the developing male Wistar(Han) rat I: no decrease in epididymal sperm count after a single acute dose

It has been reported that fetal exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes defects in the male reproductive system of the rat. We set out to replicate and extend these effects using a robust experimental design. Groups of 75 (control vehicle) or 55 (50, 200 or 1000 ng of TCDD kg-1 bodyweight) female Wistar(Han) rats were exposed to TCDD on Gestational Day (GD) 15, then allowed to litter. The high dose group dams showed no sustained weight loss compared to control, but four animals had total litter loss. Pups in the high dose group showed reduced body weight up till day 21, and pups in the medium dose group showed reduced body weight in the first week post partum. Balano-preputial separation (BPS) was significantly delayed in the high dose group male offspring. There were no significant effects of treatment when the offspring were subjected to a functional observational battery, or mated with females to assess reproductive capability. 25 males per group were killed on post natal day (PND) 70, and ~60 animals per group (~30 for the high dose group) on PND120 to assess seminology and other endpoints. At PND120, the two highest dose groups showed a statistically significant elevation of sperm counts, compared to control; however, this effect was small (~30%), within the normal range of sperm counts for this strain of rat, was not reflected in testicular spermatid counts nor PND70 data, and is therefore postulated to have no biological significance. Although there was an increase in the proportion of abnormal sperm at PND70, seminology parameters were otherwise unremarkable. Testis weights in the high dose group were slightly decreased at PND 70 and 120, and at PND120, brain weights were decreased in the high dose group, liver to body weight ratios were increased for all three dose groups, with an increase in inflammatory cell foci in the epididymis in the high dose group. These data show that TCDD is a potent developmental toxin after exposure of the developing fetus, but that acute developmental exposure to TCDD on GD15 caused no decrease in sperm counts.

Caracterização físico-química e ações farmacológicas hepatoprotetora, antiinflamatória, pró-angiogênica, antioxidante e anticoagulante da fração rica em fucana 0,8FRF 0,8 da alga marrom Lobophora variegata

This study examines the physical and chemical composition and the pharmacological effects of brown seaweed FRF 0.8 Lobophora variegata. Fractionation of the crude extract was done with the concentration of 0.8 volumes of acetone, obtaining the FRF 0.8. The physicochemical characterization showed that it was a fucana sulfated. Anti-inflammatory activity was assessed by paw edema model by the high rates of inhibition of the edema and the best results were in the fourth hour after induction (100 ± 1.4% at the dose of 75 mg / kg) and by the strong inhibitory activity of the enzyme myeloperoxidase (91.45% at the dose of 25 mg / kg). The hepataproteção was demonstrated by measurements of enzymatic and metabolic parameters indicative of liver damage, such as bilirubin (reduction in 68.81%, 70.68% and 68.21% for bilirubin total, direct and indirect, respectively at a dose of 75 mg / kg), ALT, AST and γ-GT (decrease of 76.93%, 44.58% and 50% respectively at a dose of 75 mg / kg) by analysis of histological slides of liver tissue, confirming that hepatoprotective effect the polymers of carbohydrates, showing a reduction in tissue damage caused by CCl4 and the inhibition of the enzyme complex of cytochrome P 450 (increasing sleep time in 54.6% and reducing the latency time in 71.43%). The effectiveness of the FRF 0.8 angiogenesis was examined in chorioallantoic membrane (CAM) of fertilized eggs, with the density of capillaries evaluated and scored, showing an effect proangigênico at all concentrations tested FRF (10 mg- 1000 mg). The FRF showed antioxidant activity on free radicals (by inhibiting Superoxide Radical in 55.62 ± 2.10%, Lipid Peroxidation in 100.15 ± 0.01%, Hydroxyl Radical in 41.84 ± 0.001% and 71.47 Peroxide in ± 2.69% at concentration of 0.62 mg / mL). The anticoagulant activity was observed with prolongation of activated partial thromboplastin time (aPTT) at 50 mg (> 240 s), showing that its action occurs in the intrinsic pathway of the coagulation cascade. Thus, our results indicate that these sulfated polysaccharides are an important pharmacological target

Validación de un score de neumonía bacteriana como métodos para predecir etiología en pacientes de 1 mes a 8 años de edad, ingresados en Hospital Nacional de Niños Benjamín Bloom, Mayo - Diciembre 2009.

Determinar la etiología de las neumonías para decidir su tratamiento, no es simple, sin una prueba confirmatoria los médicos se apoyan de evaluaciones clínicas, radiológicas, de laboratorio y edad de pacientes, es por ello, que se estudió una regla de predicción clínica que combinó varios elementos que incrementaron la capacidad diagnóstica de dicha patología. Objetivo: Se evaluó la capacidad diagnóstica de una escala de puntaje para predecir etiología en niños con neumonía (Bacterial Pneumonia Score), y otras variables no incluidas en el score que resultaron asociadas a las neumonías. Estudio descriptivo, transversal, retrospectivo de evaluación de prueba diagnóstica, en Hospital Benjamin Bloom, desde mayo a diciembre 2009, incluyendo ≥1 mes a 8 años de edad, hospitalizados por neumonía, con datos de temperatura, radiografía torácica, hemograma, hisopado nasofaríngeo, se excluyeron los pacientes que necesitaron cuidados en UCI o intermedios, con patologías respiratorias crónicas, cuerpo extraño o aspiración, enfermedades oncológicas, inmunodeficiencias o neumonía con radiografía 8 semanas previo al ingreso en estudio. Resultados: Se incluyeron 275 pacientes, de ellos 120 diagnosticados con patología viral y 180 con etiología bacteriana, se registraron datos del expediente clínico a través de un cuestionario que contempló variables del BPS además de otras que resultaron estadísticamente asociadas por Chi cuadrado. Según el score ≥ 4 puntos se calculó una sensibilidad de 79% (IC 95%: 75-82), especificidad de 91% (IC 95%: 85-96), valor predictivo positivo de 94% (IC 95% 90-97) y valor predictivo negativo de 69% (IC %: 61-78).y una eficacia diagnostica bajo curva ROC de 0.88. Conclusión: El BPS resultó tener buena capacidad para identificar la mayoría de pacientes con neumonía acteriana, pero se mostró más preciso para descartarla.

Serie de documentos Facultad de Jurisprudencia N° 75. Estado del arte del proyecto de invstigación. "Los daños antijurídicos producidos por los agentes de las Fuerzas Militares: límites al ejercicio de la fuerza del Estado como función pública"

La concepción de Estado moderno está íntimamente vinculada al ejercicio del monopolio legítimo de la fuerza, en tanto supone que la violencia es una de las principales prerrogativas que el Estado pretende detentar, para constituirse en una organización política de poder que perdure en la sociedad en la que se instaura. En este sentido, el proyecto de investigación tiene como uno de sus objetivos específicos, identificar, caracterizar y analizar los daños antijurídicos por los cuales el Comité de Conciliación del Ministerio de Defensa Nacional autoriza el ejercicio de la acción de repetición contra los funcionarios o ex-funcionarios de las Fuerzas Militares, limitando el análisis al periodo transcurrido durante los años 2010 a 2016. Lo anterior, con el fin de establecer cuáles son las causas generadoras de responsabilidad más frecuentes en las que han incurrido los agentes de la entidad, para luego observar su impacto en el erario de la nación y verificar cómo se constituyen en una necesidad de imposición de límites al ejercicio de la fuerza del Estado.

Up-regulation Of Dnam-1 And Nkp30, Associated With Improvement Of Nk Cells Activation After Long-term Culture Of Mononuclear Cells From Patients With Ovarian Neoplasia.

This study aimed at evaluating the functional activation and activating receptors expression on resting, short- and long-term NK and NK-like T cells from blood of ovarian neoplasia patients. Blood from patients with adnexal benign alterations (n = 10) and ovarian cancer (grade I-IV n = 14) were collected after signed consent. Effector cells activation was evaluated by the expression of the CD107a molecule. Short-term culture was conducted overnight with IL-2 and long-term culture for 21 days, by a method designed to expand CD56(+) lymphocytes. Short-term culture significantly increased NK cells activation compared to resting NK cells (p<0.05), however, the long-term procedure supported an even higher increase (p<0.001). Resting NK-like T cells showed poor activation, which was not altered by the culture procedures. The long-term culture effectively increased the expression of the activating receptors on NK and NK-like T cells, either by increasing the number of cells expressing a given receptor and/or by up-regulating their expression intensity. As a conclusion, the long-term culture system employed, resulted in a high number of functional NK cells. The culture system was particularly efficient on the up-regulation of NKp30 and DNAM-1 receptors on NK cells.

Icatibant, An Inhibitor Of Bradykinin Receptor 2, For Hereditary Angioedema Attacks: Prospective Experimental Single-cohort Study.

Hereditary angioedema (HAE) with C1 inhibitor deficiency manifests as recurrent episodes of edema involving the skin, upper respiratory tract and gastrointestinal tract. It can be lethal due to asphyxia. The aim here was to evaluate the response to therapy for these attacks using icatibant, an inhibitor of the bradykinin receptor, which was recently introduced into Brazil. Prospective experimental single-cohort study on the efficacy and safety of icatibant for HAE patients. Patients with a confirmed HAE diagnosis were enrolled according to symptoms and regardless of the time since onset of the attack. Icatibant was administered in accordance with the protocol that has been approved in Brazil. Symptom severity was assessed continuously and adverse events were monitored. 24 attacks in 20 HAE patients were treated (female/male 19:1; 19-55 years; median 29 years of age). The symptoms were: subcutaneous edema (22/24); abdominal pain (15/24) and upper airway obstruction (10/24). The time taken until onset of relief was: 5-10 minutes (5/24; 20.8%); 10-20 (5/24; 20.8%); 20-30 (8/24; 33.4%); 30-60 (5/24; 20.8%); and 2 hours (1/24; 4.3%). The time taken for complete resolution of symptoms ranged from 4.3 to 33.4 hours. Adverse effects were only reported at injection sites. Mild to moderate erythema and/or feelings of burning were reported by 15/24 patients, itching by 3 and no adverse effects in 6. HAE type I patients who received icatibant responded promptly; most achieved improved symptom severity within 30 minutes. Local adverse events occurred in 75% of the patients.
