BACKGROUND To evaluate if, among children aged 3 to 15 years, influenza vaccination for multiple seasons affects the proportion sero-protected. METHODOLOGY/PRINCIPAL FINDINGS Participants were 131 healthy children aged 3-15 years. Participants were vaccinated with trivalent inactivated seasonal influenza vaccine (TIV) over the 2005-06, 2006-07 and 2007-8 seasons. Number of seasons vaccinated ...

The dynamics of 15 taxa pollen seasons in Kraków, in 1991-2008 was monitored using a Burkard volumetric spore trap of the Hirst design. The highest daily pollen concentrations were achieved in the first half of May, and they were caused mainly by Betula and Pinus pollen. The second period of the high concentrations took place from the middle of July to the end of August (mainly Urtica pollen). ...

The effects of seasonal variations and the effects of acute hypothermia (8.0 degrees) and/or physostigmine (PHY) in different seasons have been studied on the tissue glycogen, cardiac acetylcholine (ACh) and blood sugar contents in frogs. Seasonal variations had no significant effect on cardiac cholinergic activity. However, cardiac ACh concentration was significantly reduced by hypothermia in ...

The study was conducted on Vencobb broiler chicks to ascertain the antistress affects of Zist, Zeetress and a combination of Amla and Turmeric during summer, rainy and winter seasons and thereby the haematological changes of birds revealed that during all the three seasons a marked improvement in Haemoglobin was encountered in all the three groups where herbal preparations were supplemented. A ...

Disease activity assessment is one of the most pivotal aspects in the care of RA patients. Composite measures of disease activity are superior to individual measures, since they capture the multiple facets of the disease. Since swollen joint counts correlate with joint damage progression and tender joint counts with physical function, composite scores that include joint counts are preferable. T...

The FoxO family of forkhead transcription factors is at the crossroads of many signal transduction pathways that are evolutionarily conserved. Such pathways have been co-opted in differentiated tissues for a variety of vital and specialized functions, such as differentiation, proliferation, and survival in cells as diverse as adipocytes, hepatocytes, β-cells, myoblasts, thymocytes, and cancer c...

We address the problem of robust visual data association across seasons and viewpoints. The predominant methods in this area are typically appearance–based, which lose representational power in outdoor and natural environments that have significant variation in appearance. After a natural environment is surveyed multiple times, we recover its 3D structure in a map, which provides the basis for ...

this study was aimed to evaluate the effect of gnrh injection on semen ejaculate characteristics in awassi rams collected in breeding and non breeding seasons. the study was conducted in late summer to early autumn when breeding activity commences, and in winter during the non breeding season. twelve mature awassi rams were used in this study. animals were randomly allocated into two equal grou...

Lake Chad, located in the middle of the African Sahel belt, underwent dramatic decreases in the 1970s and 1980s leaving less than ten percent of its 1960s surface water extent as open water. In this paper, we present an extended record (dry seasons 1988–2016) of the total surface water area of the lake (including both open water and flooded vegetation) derived using Land Surface Temperature (LS...

BACKGROUND Estimates of influenza vaccine effectiveness in elderly individuals are largely from observational studies, which are susceptible to bias. Instrumental variable (IV) methods control for overt and hidden biases in observational studies. METHODS We used linked health administrative databases in Ontario to examine the association between influenza vaccination and all-cause mortality a...
