Systemic And Mucosal Infection Program Protective Memory Cd8 T Cells In The Vaginal Mucosa., Thandi M. Onami, P. K. Suvas, H. M. Dech, J. Zeng
Systemic And Mucosal Infection Program Protective Memory Cd8 T Cells In The Vaginal Mucosa., Thandi M. Onami, P. K. Suvas, H. M. Dech, J. Zeng

Whether mucosal immunization is required for optimal protective CD8 T cell memory at mucosal surfaces is controversial. In this study, using an adoptive transfer system, we compare the efficacy of two routes of acute lymphocytic choriomeningitis viral infection on the generation, maintenance, and localization of Ag-specific CD8 T cells in tissues, including the vaginal mucosa. Surprisingly, at day 8, i.p. infection results in higher numbers of Ag-specific CD8 T cells in the vaginal mucosa and iliac lymph node, as well as 2-3x more Ag-specific CD8 T cells that coexpress both IFN-gamma and TNF-alpha in comparison to the intranasal route of …

Smallpox, Richard N. Bradley
Richard N Bradley
Description Viral infection of the human respiratory tract. Causes Infection by variola virus. Risk Factors Exposure to a biological warfare or bioterror attack or contact with an infected person. Symptoms
Fever, cough and body aches, followed by a spotted, bumpy rash.
Diagnosis
Confirmed by testing blood or the fluid from the blisters.
Treatments
None currently approved but experts are testing some medications.
Pathogenesis
The virus enters and multiplies in the respiratory passages.
Prevention
Avoid those with the disease. During an outbreak a vaccine is available that will prevent the disease or lessen its severity.
Epidemiology
Completely eradicated from nature, but …
Development Of A Mechanistic Model To Represent The Dynamics Of Liquid Flow Out Of The Rumen And To Predict The Rate Of Passage Of Liquid In Dairy Cattle, S Seo, Cristina Lanzas, L O. Tedeschi, D G. Fox
Development Of A Mechanistic Model To Represent The Dynamics Of Liquid Flow Out Of The Rumen And To Predict The Rate Of Passage Of Liquid In Dairy Cattle, S Seo, Cristina Lanzas, L O. Tedeschi, D G. Fox

A mechanistic and dynamic model was developed to represent the physiological aspects of liquid dynamics in the rumen and to quantitatively predict liquid flow out of the reticulorumen (RR). The model is composed of 2 inflows (water consumption and salivary secretion), one outflow (liquid flow through the reticulo-omasal orifice (ROO), and one in-and-out flow (liquid flux through the rumen wall). We assumed that liquid flow through the ROO was coordinated with the primary reticular contraction, which is characterized by its frequency, duration, and amplitude during eating, ruminating, and resting. A database was developed to predict each component of the model. …
Race, Gender And Stroke Subtypes Mortality In Sao Paulo, Brazil., Paulo A. Lotufo
Race, Gender And Stroke Subtypes Mortality In Sao Paulo, Brazil., Paulo A. Lotufo

Stroke mortality rates have a discrepant distribution according to socioeconomic variables as social exclusion in Brazil. Recently, data from race has been available from the official health statistics considering five categories: White, Mixed, Black, Asian and Native. We addressed in the city of São Paulo, Brazil, an analysis of cerebrovascular mortality according to race (excluding Asian and Native due to small number of events) and gender during 1999-2001 for people aged 30 to 79 years-old. For all cerebrovascular diseases, age-adjusted mortality rates (x 100,000) for men were higher for Black (150.2), intermediate for Mixed (124.2) and lower for White (104.5) …

Production efficiency decreases when diets are not properly balanced for protein. Sensitivity analyses of the protein fractionation schemes used by the National Research Council Nutrient Requirement of Dairy Cattle (NRC) and the Cornell Net Carbohydrate and Protein System (CNCPS) were conducted to assess the influence of the uncertainty in feed inputs and the assumptions underlying the CNCPS scheme on metabolizable protein and amino acid predictions. Monte Carlo techniques were used. Two lactating dairy cow diets with low and high protein content were developed for the analysis. A feed database provided by a commercial laboratory and published sources were used to …

Grain fermentability largely determines the feed value of grains for ruminants. Our objective was to evaluate the variation in kinetics of gas production of cereal grains and the relationship among gas production, chemical composition and feed value. Eighteen barley, 99 corn, 23 sorghum, and 57 wheat samples were fermented in vitro for 48 h. Gas production was measured with a computerized system and an exponential model was fitted to the data. The impact of the variation in composition and kinetics on the feed value of grains in feedlot rations was assessed with the Cornell Net Carbohydrate and Protein System (CNCPS). …

Balancing ruminant diets for appropriate levels and types of dietary carbohydrates (CHO) is necessary to maximize production while assuring the health of the animals. Several feed fractions (i.e., volatile fatty acids (VFA), lactate, sugars, starch) are now being measured in some commercial feed laboratories and this information may assist in better formulating diets. A CHO fractionation scheme based on ruminal degradation characteristics needed for nutritional models is described and its impact on predictions with the Cornell Net Carbohydrate and Protein System (CNCPS) is assessed. Dietary CHO are divided into eight fractions: the CA1 is volatile fatty acids (VFA), CA2 is …
