Search for pair production of third-generation scalar leptoquarks and top squarks in proton-proton collisions at v root s=8 TeV

A search for pair production of third-generation scalar leptoquarks and supersymmetric top quark partners, top squarks, in final states involving tau leptons and bottom quarks is presented. The search uses events from a data sample of proton-proton collisions corresponding to an integrated luminosity of 19.7 fb(-1), collected with the CMS detector at the LHC with root s = 8 TeV. The number of observed events is found to be in agreement with the expected standard model background. Third-generation scalar leptoquarks with masses below 740 GeV are excluded at 95% confidence level, assuming a 100% branching fraction for the leptoquark decay to a tau lepton and a bottom quark. In addition, this mass limit applies directly to top squarks decaying via an R-parity violating coupling. lambda(') (333). The search also considers a similar signature from top squarks undergoing a chargino-mediated decay involving the Rparity violating coupling. lambda(')(3jk). Each top squark decays to a tau lepton, a bottom quark, and two light quarks. Top squarks in this model with masses below 580 GeV are excluded at 95% confidence level. The constraint on the leptoquark mass is the most stringent to date, and this is the first search for top squarks decaying via. lambda(')(3jk). (C) 2014 The Authors. Published by Elsevier B. V.

Ciência e literatura na Itália do século XX

This essay intends to analise the relationship between science and literature in Italy in the 20th century. I will remark the considerations about science and literature made by italian writers like Calvino and Levi.

Performance and parasite control of different genetic groups of lambs finished in irrigated pasture

The aim of this study was to compare the following four genetic groups of hair sheep: Santa Inês (SI), Morada Nova (MN), Brazilian Somali (BS), and the F1 1/2Dorper x 1/2Morada Nova crossbreed on traits related to growth and parasitic infection. Thirty-three male lambs of the same age and of simple birth, under the same pre-weaning management conditions were used in the experiment. After weaning the animals were housed in a completely randomized design in paddocks made of Panicum maximum cv. Tanzania. Along the course of the research, the performance of the four groups of sheep was observed to be negatively affected by gastrointestinal parasites, but there was a genotype effect to the average daily weight gain (ADWG), where the SI and F1 genotypes presented higher values. The effects of genotype, time and genotype x time interaction were significant in weight and corporal score (CS) measurements. The BS lambs had the highest CS values throughout the experiment despite not presenting greater weight gain when compared to the SI and F1 breeds. There were also significant effects of time and genotype x time interaction for packed cell volume (PCV) and FAMACHA© score (FAM) and only the time effect was significant in the total number of eggs per gram (EPG) and total plasma protein (TPP). The MN lambs showed higher PCV values and unlike the other groups, presented a FAMACHA© score below 3 and PCV above 23% even having a higher EPG tendency, especially in the initial phase, indicating a possible higher resilience to infection caused by gastrointestinal parasites.

Response to Chemotherapy in Overweight/Obese Patients With Low-Risk Gestational Trophoblastic Neoplasia

Objective Despite rising global obesity rates, the impact of obesity on gestational trophoblastic neoplasia (GTN) remains uninvestigated. This study aimed at investigating whether overweight/obesity relates to response to chemotherapy in low-risk GTN patients.Methods This nonconcurrent cohort study included 300 patients with International Federation of Gynecology and Obstetrics-defined postmolar low-risk GTN treated with a single-agent chemotherapymethotrexate or actinomycin-D (actD)between 1973 and 2012 at the New England Trophoblastic Disease Center. Chemotherapy dosing was based on actual body weight regardless of obesity status, except for 5-day courses or pulse regimens of actD. Patients were classified as overweight/obese (body mass index [BMI] 25 kg/m(2)) or non-overweight/obese (BMI <25 kg/m(2)). Information on patient characteristics and response to chemotherapy (need for second-line chemotherapy, reason for changing to an alternative chemotherapy, number of cycles, need for combination chemotherapy, and time to human chorionic gonadotropin remission) was obtained.Results Of 300 low-risk GTN patients, 81 (27%) were overweight/obese. Overweight/obese patients were older than the non-overweight/obese patients (median age: 30 vs 28 years, P = 0.004). First-line therapy using actD was more frequent in overweight/obese patients (6.2% vs 1.4%, P = 0.036). Resistance and toxicity were similar between groups. No significant difference in the number of chemotherapy cycles needed for remission or time required to achieve remission was found between groups.Conclusions No association between overweight/obesity and low-risk GTN outcomes was found. Current chemotherapy dosing using BMI seems to be appropriate for overweight/obese patients with low-risk GTN.

Evaluation of dietary intake of calcium in adult subjects with idiopathic arterial hypertension

The calcium-intake relationship with other alimentary and anthropometric variables was investigates in a group of 60 adult (19-75 year-old) subjects, 50 females and 10 males, with essential arterial hypertension (DAP > 90 mmHg). The calcium intake was assessed by three different protocols: 24-hour food intake recall, food-frequency questionnaire and 3 day self-food intake register, repeated along with anthropometric measurements on three different occasions (2-15 month-intervals). The calcium intake assessed by the three methods, as well as the anthropometric data, were statistically similar on all three occasions. The mean data were then compared with those form the control, composed of 75 healthy subjects matched with the hypertensive group by age and sex. The patients ingested less calcium (mean +/- SD) than the controls on the daily (517 +/- 271 x 740 +/- 353 mg/d) and body-weight (8.1 +/- 5.0 x 11.4 +/- 5.9 mg/kg/d) basis. Among the males the calcium intake was the only difference found between groups and could be attributed to the lower intake of calcium-rich foods. The hypertensive females showed also higher lean-body mass (Body-mass index and arm muscle circumference). Thus the calcium intake discriminated both groups being associated with changes in other nutritional parameters only in females.
