Descritores epidérmicos de gramíneas (Poaceae): um guia para identificação da dieta de herbívoros usando o programa Delta.
Este guia tem como objetivo auxiliar os técnicos nas leituras de lâminas fecais a partir da definição de decritores anatômicos da epiderme foliar de gramíneas que foram inseridos no sistema DELTADIET, desenvolvido pela Embrapa Pantanal, Royal Zoological Society of Scotland e apoio de outras Instituições. Essas informações serão úteis não apenas como guia para a identificação da dieta dos animais do Pantanal como também para animais de outras regiões, além de contribuir para a caracterização das forrageiras nativas da região.bitstream/item/79824/1/BP95.pd

Descritores epidérmicos de cyperaceae forrageiras - guia para identificação da dieta de herbívoros usando o programa Delta.
Este Boletim de Pesquisa lista os descritores anatômicos da epiderme das folhas das forrageiras de Cyperaceae. Esta família constitui uma das três famílias de forrageiras mais importantes do Pantanal, com aproximadamente 90 espécies. Como muitas dessas espécies fazem parte da dieta dos diferentes herbívoros domésticos e silvestres que habitam o Pantanal, a definição desses descritores epidérmicos para uso no sistema Delta é de fundamental importância para a leitura de lâminas fecais visando a identificação da dieta. Esta publicação, junto com os boletins de pesquisa números 95 e 96, vai facilitar o uso do programa Delta para estudos da dieta de herbívoros no Pantanal, e também para o desenvolvimento de adaptação para estudos desse tipo em outras regiões do país.bitstream/item/79826/1/BP97.pd

Stability and Clinical Efficacy of Moisturizing Cosmetic Formulations Containing Vitamins C and E
The addition of different active substances in cosmetics, e.g. vitamins and their derivatives, has been quite frequent. In this
way, it is fundamental to evaluate the stability and efficacy of cosmetic formulations containing these ingredients. The
objective of this work was to evaluate the physical stability and the clinical efficacy of moisturizing cosmetic formulations
based on panthenol, and containing ascorbyl tetraisopalmitate and α-tocopherol acetate. Formulations were developed
with panthenol (FA), panthenol and ascorbyl tetraisopalmitate and α-tocopherol acetate (FBC). The latter was submitted
to rheological behavior analysis and all were characterized as stable. Next, they were subjectively and objectively
analyzed for clinical efficacy in 25 volunteers. Sensory evaluation and biophysical and skin imaging techniques were used
to measure stratum corneum water content, transepidermal water loss (TEWL), and skin microrelief. These were carried
out before application of the formulations and then after 3 hours. The formulations studied showed acceptable stability
according to the physical aspects under consideration. In the clinical efficacy studies, both formulations significantly
improved skin hydration and reduced TEWL. There was also improvement in skin microrelief but these results were not
statistically significant. FBC received higher scores than FAin the sensory analysis as there was a significant improvement
in the skin's smoothness, besides being preferred in purchase intent
Glucemia como factor de riesgo en pacientes internados en la Unidad de Cuidados Intensivos de Adultos del Hospital de Clínicas
Objetivo: Determinar la relación entre glucemias al ingreso y la evolución de los pacientesadmitidos a la Unidad de Cuidados Intensivos de Adultos (UCIA). Material y Métodos: estudio de cohorte retrospectivo de pacientes en la UCIA, tomando un muestreo, según distintos estratos de glucemia en mg/dL (Gl65; G2 66 a 79; G3 80 a 199 y G4200). Resultados: 413 pacientes, con edad media 48.89 años ±19; glucemia media al ingreso de 168.8 mg/dL (±93). 11.9% eran diabéticos conocidos. Al ingreso el Apache II fue 16±9, con una mortalidad global de 39.7%. Se constataron infecciones intrahospitalarias en 22.8%. La mortalidad en G4 fue de 49,5% vs. 35.4% en G3 (RR 1,41 p=0.008); en cirugías programadas fue en G4 de 30.6% y 14.7% en G3 (RR 2,07 p=0,04), con una tendencia significativa en las cirugías cardiacas (RR 2,33 p=0,11) y neurológicas (RR 3,33 p=0,26); la mortalidad en las cirugías de urgencia fue en G4 44,4% vs. 44,1% en G3 (RR 1,01 p=0,97). Los cuadros médicos en general presentaron una mortalidad de 76 % en G4 vs. 45% en G3 (RR 1,53 p=0,004). Los cuadros coronarios reportaron una mortalidad en G4 de 42 % vs. 10% en G3 (RR 7,13 p=0,001); en cuanto a hipoglucemia, existió una tendencia a mayor mortalidad general en G1 en comparación a G2 y G3 (35% vs. 63,6%) (RR 1,80 p=0,05) Conclusiones: La mortalidad general, de cirugías programadas y síndromes coronarios agudos fue mayor en forma significativa cuando la glucemia de ingreso fue 200 mg/dL
Variação na produção e valor nutritivo de acessos das gramíneas nativas Paspalum oteroi e Mesosetum chaseae sob condições de seca e solos de baixa fertilidade.
O Pantanal é uma extensa planície caracterizada por diferentes formações vegetais presentes em áreas habitualmente úmidas, sazonais e secas. As áreas habitualmente secas, geralmente são constituídas de formações savânicas e de campo, muitas das quais possuem solos arenosos e de baixa fertilidade natural, o que reflete na baixa produção e qualidades das forrageiras.Edição especial dos Anais V Congresso Brasileiro de Recursos Genéticos
Confusing non-standard neutrino interactions with oscillations at a neutrino factory
Most neutrino mass theories contain non-standard interactions (NSI) of
neutrinos which can be either non-universal (NU) or flavor-changing (FC). We
study the impact of such interactions on the determination of neutrino mixing
parameters at a neutrino factory using the so-called ``golden channels''
\pnu{e}\to\pnu{\mu} for the measurement of \theta_{13}. We show that a certain
combination of FC interactions in neutrino source and earth matter can give
exactly the same signal as oscillations arising due to \theta_{13}. This
implies that information about \theta_{13} can only be obtained if bounds on
NSI are available. Taking into account the existing bounds on FC interactions,
this leads to a drastic loss in sensitivity in \theta_{13}, at least two orders
of magnitude. A near detector at a neutrino factory offers the possibility to
obtain stringent bounds on some NSI parameters. Such near site detector
constitutes an essential ingredient of a neutrino factory and a necessary step
towards the determination of \theta_{13} and subsequent study of leptonic CP
violation.Comment: 23 pages, 5 figures, improved version, accepted for publication in

BDNF and NGF signalling in early phases of psychosis: relationship with inflammation and response to antipsychotics after a 1 year
Previous studies have indicated systemic deregulation of the proinflammatory or anti-inflammatory balance in individuals with first-episode psychosis (FEP) that persists 12 months later. To identify potential risk/protective factors and associations with symptom severity, we assessed possible changes in plasma levels of neurotrophins (brain-derived neurotrophic factor [BDNF] and nerve growth factor [NGF]) and their receptors in peripheral blood mononuclear cells (PBMCs). Expression of the 2 forms of BDNF receptors (active TrkB-FL and inactiveTrkB-T1) in PBMCs of FEP patients changed over time, TrkB-FL expression increasing by 1 year after diagnosis, while TrkB-T1 expression decreased. The TrkB-FL/TrkB-T1 ratio (hereafter FL/T1 ratio) increased during follow-up in the nonaffective psychosis group only, suggesting different underlying pathophysiological mechanisms in subgroups of FEP patients. Further, the expression of the main NGF receptor, TrkA, generally increased in patients at follow-up. After adjusting for potential confounders, baseline levels of inducible isoforms of nitric oxide synthase, cyclooxygenase, and nuclear transcription factor were significantly associated with the FL/T1 ratio, suggesting that more inflammation is associated with higher values of this ratio. Interestingly, the FL/T1 ratio might have a role as a predictor of functioning, a regression model of functioning at 1 year suggesting that the effect of the FL/T1 ratio at baseline on functioning at 1 year depended on whether patients were treated with antipsychotics. These findings may have translational relevance; specifically, it might be useful to assess the expression of TrkB receptor isoforms before initiating antipsychotic treatment in FEP
