Comparison of DeLorme with Oxford resistance training techniques: effects of training on muscle damage markers

Aim: The purpose of this study was comparing DeLorme with Oxford methods through ten repetition maximum (10 RM) performance and serum creatine kinase (CK) and lactate dehydrogenase (LDH) activity. Methods: Before and after four weeks of training with the DEL (n=16) or OXF (n=16) resistance training (RT) methods, rest and post exercise serum CK activity, serum LDH activity and 10 RM performance were measured and compared. Results: Both methods provide higher 10 RM results after training without significant differences between groups (p<0.05). Rest and post exercise CK and LDH activity was less after training with DeLorme (DEL) and Oxford (OXF), but the magnitude of the relative peak response (48-hr our 72-hr post exercise, respectively) was higher after each training protocol. Comparisons of CK activity between groups display non-significant differences. Conclusion: DEL or OXF training methods cause the same improvement on muscle performance and both alters CK activity without differences between methods in a 4-week RT program

Domestic feline cutaneous leishmaniasis in the municipality of Ribas do Rio Pardo, Mato Grosso do Sul state, Brazil: a case report

Cutaneous leishmaniases are anthropozoonoses that involve many species of Leishmania and a wide variety of wild mammalian hosts, thus presenting high importance to public health. This study reports the second case of feline leishmaniasis in Mato Grosso do Sul state, in which Leishmania (Leishmania) amazonensis was found in a domestic cat from Ribas do Rio Pardo. Clinical signs were similar to those observed in other diseases commonly diagnosed in cats, such as cryptococcosis and sporotrichosis. Cutaneous leishmaniasis should, therefore, be added to differential diagnoses by feline veterinary practitioners, and also adequate investigations should be carried out to verify the relevance of domestic cats as L. amazonensis reservoirs

Ratio of the Isolated Photon Cross Sections at \sqrt{s} = 630 and 1800 GeV

The inclusive cross section for production of isolated photons has been measured in \pbarp collisions at $\sqrt{s} = 630$ GeV with the \D0 detector at the Fermilab Tevatron Collider. The photons span a transverse energy ($E_T$) range from 7-49 GeV and have pseudorapidity $|\eta| < 2.5$. This measurement is combined with to previous \D0 result at $\sqrt{s} = 1800$ GeV to form a ratio of the cross sections. Comparison of next-to-leading order QCD with the measured cross section at 630 GeV and ratio of cross sections show satisfactory agreement in most of the $E_T$ range.Comment: 7 pages.

Performance of the CMS Cathode Strip Chambers with Cosmic Rays

The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns

Regional movements of the tiger shark, Galeocerdo cuvier, off northeastern Brazil: inferences regarding shark attack hazard

An abnormally high shark attack rate verified off Recife could be related to migratory behavior of tiger sharks. This situation started after the construction of the Suape port to the south of Recife. A previous study suggested that attacking sharks could be following northward currents and that they were being attracted shoreward by approaching vessels. In this scenario, such northward movement pattern could imply a higher probability of sharks accessing the littoral area of Recife after leaving Suape. Pop-up satellite archival taus were deployed on five tiger sharks caught off Recife to assess their movement patterns off northeastern Brazil. All tags transmitted from northward latitudes after 7-74 days of freedom. The shorter, soak distance between deployment and pop-up locations ranged between 33-209 km and implied minimum average speeds of 0.02-0.98 km.h(-1). Both pop-up locations and depth data suggest that tiger shark movements were conducted mostly over the continental shelf. The smaller sharks moved to deeper waters within 24 hours after releasing, but they assumed a shallower (< 50 m) vertical distribution for most of the monitoring period. While presenting the first data on tiger shark movements in the South Atlantic, this study also adds new information for the reasoning of the high shark attack rate verified in this region,State Government of Pernambuco and Petrobras (Brazil); Fundacao para a Ciencia e Tecnologia (Portugal) [MCTES/FCT/SFRH/BD/37065/2007

Questionnaire Hearing Handicap Inventory for the Elderly - Screening version (HHIE-S): sensitivity and specificity study

PURPOSE: To investigate the sensitivity and specificity of the questionnaire Hearing Handicap Inventory for the Elderly - Screening version (HHIE-S) in the hearing screening of elderly people who seek for different health care services (audiological clinic and other clinics). METHODS: The hearing of 78 elderly - 23 attended at the Discipline of Geriatrics and Gerontology of the institution who did not, necessarily, have complaints regarding their hearing, and 55 attended at the Audiology Clinic of the same institution with complaints related to the auditory and/or vestibular systems - was assessed. The HHIE-S questionnaire was applied, and its total score was divided into three categories, according to the handicap perception. RESULTS: A statistically significant relationship was found between handicap and degree of hearing loss in both patients from the Audiology Clinic (p=0.009*) and from the Geriatrics Clinic (p=0.002). In the first group, the HHIE-S questionnaire showed low sensitivity (23.5%) and high specificity (73.7%). In the group of patients from the Geriatrics Clinic, the values of sensitivity (94.7%) and specificity (75%) were both high. CONCLUSIONS: There was positive association between the degree of hearing loss and the handicap referred by both groups of subjects. The HHIE-S questionnaire is a hearing screening instrument with high sensitivity and specificity in identifying hearing loss in elderly people that seek health care services that are not specific for attention related to hearing disorders.OBJETIVO: Investigar a sensibilidade e especificidade do questionário Hearing Handicap Inventory for the Elderly - Screening version (HHIE-S) na triagem auditiva de idosos que procuram diferentes serviços de atenção à saúde (clínica audiológica e outras clínicas). MÉTODOS: Foi avaliada a audição de 78 idosos - 23 atendidos na disciplina de Geriatria e Gerontologia da instituição de origem, que não tinham, necessariamente, queixas relacionadas à audição, e 55 atendidos no Ambulatório de Audiologia da mesma instituição, com queixas relacionadas aos sistemas auditivo e/ou vestibular. Foi aplicado o HHIE-S, cujo escore total foi dividido em três categorias, de acordo com a percepção do handicap. RESULTADOS: Houve relação estatisticamente significante entre handicap e grau de perda auditiva no grupo de pacientes do Ambulatório de Audiologia (p=0,009), e no grupo de pacientes do Ambulatório de Geriatria (p=0,002). No primeiro grupo, o questionário HHIE-S revelou baixa sensibilidade (23,5%) e alta especificidade (73,7%). No grupo de pacientes do setor de Geriatria, foram altos os valores de sensibilidade (94,7%) e de especificidade (75%). CONCLUSÕES: Há associação positiva entre o grau de perda auditiva e o handicap referido em ambos os grupos. O questionário HHIE-S é um instrumento de triagem auditiva com alta especificidade e sensibilidade na identificação de perdas auditivas em idosos que procuram serviços de saúde que não são específicos para atendimentos relacionados às alterações auditivas.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Irmandade da Santa Casa de Misericórdia de São PauloUniversidade Federal de São Paulo (UNIFESP)Universidade Federal de São Paulo (UNIFESP) Departamento de FonoaudiologiaUNIFESP, Depto. de FonoaudiologiaSciEL

Asteroseismology and Interferometry

Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies of solar-like pulsators, have boosted the impact of this field of research within Astrophysics and have led to a significant increase in the size of the research community. In the present paper we start by reviewing the basic observational and theoretical properties of classical and solar-like pulsators and present results from some of the most recent and outstanding studies of these stars. We centre our review on those classes of pulsators for which interferometric studies are expected to provide a significant input. We discuss current limitations to asteroseismic studies, including difficulties in mode identification and in the accurate determination of global parameters of pulsating stars, and, after a brief review of those aspects of interferometry that are most relevant in this context, anticipate how interferometric observations may contribute to overcome these limitations. Moreover, we present results of recent pilot studies of pulsating stars involving both asteroseismic and interferometric constraints and look into the future, summarizing ongoing efforts concerning the development of future instruments and satellite missions which are expected to have an impact in this field of research.Comment: Version as published in The Astronomy and Astrophysics Review, Volume 14, Issue 3-4, pp. 217-36

Understanding the chronology and occupation dynamics of oversized pit houses in the southern Brazilian highlands

A long held view about the occupation of southern proto-Je pit house villages of the southern Brazilian highlands is that these sites represent cycles of long-term abandonment and reoccupation. However, this assumption is based on an insufficient number of radiocarbon dates for individual pit houses. To address this problem, we conducted a programme of comprehensive AMS radiocarbon dating and Bayesian modelling at the deeply stratified oversized pit Houe 1, Baggio 1 site (Cal. A.D. 1395-1650), Campo Belo do Sul, Santa Catarina, Brazil. The straigraphy of House 1 revealed an unparalleled sequence of twelve well preserved floors evidencing a major change in occupation dynamics including five completely burnt collapsed roofs. The results of the radiocarbon dating allowed us to understand for the first time the occupation dynamics of an oversized pit house in the southern Brazilian highlands. The Bayesian model demonstrates that House 1 was occupied for over two centuries with no evidence of major periods of abandonment, calling into question previous models of long-term abandonment. In addition, the House 1 sequence allowed us to tie transformations in ceramic style and lithic technology to an absolute chronology. Finally, we can provide new evidence that the emergence of oversized domestic structures is a relatively recent phenomenon among the southern proto-Je. As monumental pit houses start to be bulit, small pit houses continue to be inhabited, evidencing emerging disparities in domestic architecture after AD 1000. Our research shows the importance of programmes of intensive dating of individual structures to understand occupation dynamcis and site permanence, and challenges long held assumptions that the southern Brazilian highlands were home to marginal cultures in the context of lowland South America

Measurement of the t(t)over-bar production cross section in the dilepton channel in pp collisions at √s=8 TeV

The top-antitop quark (t (t) over bar) production cross section is measured in proton-proton collisions at root s = 8 TeV with the CMS experiment at the LHC, using a data sample corresponding to an integrated luminosity of 5.3 fb(-1). The measurement is performed by analysing events with a pair of electrons or muons, or one electron and one muon, and at least two jets, one of which is identified as originating from hadronisation of a bottom quark. The measured cross section is 239 +/- 2 (stat.) +/- 11 (syst.) +/- 6 (lum.) pb, for an assumed top-quark mass of 172.5 GeV, in agreement with the prediction of the standard model

Limits on WWZ and WW\gamma couplings from p\bar{p}\to e\nu jj X events at \sqrt{s} = 1.8 TeV

We present limits on anomalous WWZ and WW-gamma couplings from a search for WW and WZ production in p-bar p collisions at sqrt(s)=1.8 TeV. We use p-bar p -> e-nu jjX events recorded with the D0 detector at the Fermilab Tevatron Collider during the 1992-1995 run. The data sample corresponds to an integrated luminosity of 96.0+-5.1 pb^(-1). Assuming identical WWZ and WW-gamma coupling parameters, the 95% CL limits on the CP-conserving couplings are -0.33<lambda<0.36 (Delta-kappa=0) and -0.43<Delta-kappa<0.59 (lambda=0), for a form factor scale Lambda = 2.0 TeV. Limits based on other assumptions are also presented.Comment: 11 pages, 2 figures, 2 table
