Performance of early weaned calves fed lasalocid
Twenty-two newborn, bull calves were used to determine the effects of
lasalocid on growth and feed intake of early-weaned calves from week 1 to 12.
Calves were assigned to lasalocid or control groups on day 3. Lasalocid-fed group
received lasalocid in milk from day 4 to 7 and in milk and pre-starter from days 7
to 14 and in starter feed from weeks 2 to 12. Lasalocid-fed calves had a
significantly higher feed consumption and greater weight gain than calves that did
not receive lasalocid. The difference became apparent only after 6 wk of age.
Lasalocid appears to be a beneficial feed additive for newborn calves
Effect of ruminal protozoa on performance of early-weaned calves
Twenty newborn bull calves assigned to two groups, protozoa-free or protozoa-inoculated, were used to determine the effects of ruminal protozoa on performance of early weaned calves. Calves in the protozoa group were inoculated via stomach tube with a suspension of ruminal protozoa at weekly intervals until a viable population was established. Calves were evaluated weekly for weight gain and feed intake. Feed intake and weight gain were not significantly different between the groups but tended to be higher in protozoa-inoculated than protozoa-free calves.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987

Age-Dependent Defects of Regulatory B Cells in Wiskott-Aldrich Syndrome Gene Knockout Mice.
The Wiskott-Aldrich syndrome (WAS) is a rare X-linked primary immunodeficiency characterized by recurrent infections, thrombocytopenia, eczema, and high incidence of malignancy and autoimmunity. The cellular mechanisms underlying autoimmune complications in WAS have been extensively studied; however, they remain incompletely defined. We investigated the characteristics of IL-10-producing CD19+CD1dhighCD5+ B cells (CD1dhighCD5+ Breg) obtained from Was gene knockout (WKO) mice and found that their numbers were significantly lower in these mice compared to wild type (WT) controls. Moreover, we found a significant age-dependent reduction of the percentage of IL-10-expressing cells in WKO CD1dhighCD5+ Breg cells as compared to age-matched WT control mice. CD1dhighCD5+ Breg cells from older WKO mice did not suppress the in vitro production of inflammatory cytokines from activated CD4+ T cells. Interestingly, CD1dhighCD5+ Breg cells from older WKO mice displayed a basal activated phenotype which may prevent normal cellular responses, among which is the expression of IL-10. These defects may contribute to the susceptibility to autoimmunity with age in patients with WAS
Digital Design Considerations for Volunteer Recruitment: Making the Implicit Promises of Volunteering More Explicit
Non-profit organisations may find it difficult to demonstrate to potential volunteers what is required in their voluntary role-resulting in a mismatch between expectations and reality for volunteers. This mismatch could be perceived as a psychological contract breach. We interviewed 18 volunteers and 7 coordinators about their experiences and expectations in order to understand how the experience of volunteers can better be captured and communicated. Further, we wished to consider how future digital platforms might capture important elements of the volunteer experience to better support recruitment, retention and recognition. We present our findings and discuss digital platform implications around the four implicit 'promises' of volunteering: the social promise, the opportunity promise, the value promise and the organisational citizenship promise. We add to literature exploring the voluntary sector by assessing the feasibility of digital interventions to support various aspects of volunteer and coordinator roles
Exploring the Quality of Life of People in North Eastern and Southern Thailand.
The assumption that development brings not only material prosperity but also a better overall quality of life lies at the heart of the development project. Against this, critics assert that development can undermine social cohesion and threaten cultural integrity. Rarely, however, is the impact of development on wellbeing rigourously analysed using empirical data. This is what the Wellbeing in Developing Countries Group at the University of Bath aims to do drawing on fieldwork carried out in four developing countries, which addresses the themes of resources, needs, agency and structure, and subjective Quality of life (QoL). The first phase of the QoL research in Thailand aimed to explore the categories and components of quality of life for people from different backgrounds and locations with the aim of developing methods for QoL assessment in the third phase of the WeD QoL research. The study presents data obtained from rural and peri-urban sites in Southern and Northeastern Thailand (two villages in Songkhla and three in Khon Kaen, Mukdaharn, and Roi-et). Participants were divided into six groups by gender and age, and were divided again by religion (Buddhist and Muslim) and wealth status in the South. Data collection was conducted between October and December 2004 using focus group discussions, semi-structured interviews, and the Person Generated Index. Content analysis was used for data analysis. The use of a qualitative approach enabled the gathering of empirical data that reflects the sources of difficulty and happiness in the lives of participants. Respondents identified 26 aspects to their quality of life, including family relations, health and longevity, income and having money, jobs, housing, education, debt, and so on. The results reveal clear similarities and differences in the role of traditions, religious beliefs, and values in the lives of people living in remote rural or peri-urban areas in Northeastern and Southern Thailand. These results, together with the findings from Peru, Ethiopia, and Bangladesh, will inform the rest of the WeD research and be used to develop measures to assess the quality of life of people living in developing countries
Microevolution during the emergence of a monophasic Salmonella Typhimurium epidemic in the United Kingdom
Microevolutionary events associated with the emergence and clonal expansion of new 27 epidemic clones of bacterial pathogens hold the key to understanding the drivers of 28 epidemiological success. We describe a comparative whole genome sequence and 29 phylogenomic analysis of monophasic Salmonella Typhimurium isolates from the UK 30 and Italy from 2005-2012. Monophasic isolates from this time formed a single clade 31 distinct from recent monophasic epidemic clones described previously from North 32 America and Spain. The current UK monophasic epidemic clones encode a novel 33 genomic island encoding resistance to heavy metals (SGI-3), and composite transposon 34 encoding antibiotic resistance genes not present in other Typhimurium isolates, that 35 may have contributed to the epidemiological success. We also report a remarkable 36 degree of genotypic variation that accumulated during clonal expansion of a UK 37 epidemic including multiple independent acquisitions of a novel prophage carrying the 38 sopE gene and multiple deletion events affecting the phase II flagellin locus
Irish athletes’ attitudes towards seeking sport psychology consultation
The aim of this study was to replicate previous research examining attitudes to sport psychology consultation conducted in the United States, Germany, and United Kingdom (Martin, Lavallee, Kellmann & Page, 2004), and New Zealand (Anderson, Hodge, Lavallee, & Martin, 2004). The study employed the Sport Psychology Attitudes-Revised (SPA-R) questionnaire (Martin, Kellman, Lavallee & Page, 2002) in order to develop an understanding of the attitudes elite Irish athletes (N=240) hold toward sport psychology and also compare these attitudes with those found in other countries. Irish athletes in this study reported a generally positive attitude toward sport psychology provision overall, and also were identified as being open to receiving sport psychology assistance, reported moderately high levels of confidence in sport psychology, and indicated the lack of accessibility and availability to these services as distinguishing factors. Comparison of results with athletes from other countries suggested that positive attitudes toward sport psychology may be based on factors not directly associated with personal experiences of sport psychology. As the provision of sport psychology increases, practitioners need to better understand athletes' attitudes toward sport psychology so they can tailor their services to best meet the needs of athletes. In order to do this, further research related to cultural and national differences is required
Backward pion-nucleon scattering
A global analysis of the world data on differential cross sections and
polarization asymmetries of backward pion-nucleon scattering for invariant
collision energies above 3 GeV is performed in a Regge model. Including the
, , and trajectories, we
reproduce both angular distributions and polarization data for small values of
the Mandelstam variable , in contrast to previous analyses. The model
amplitude is used to obtain evidence for baryon resonances with mass below 3
GeV. Our analysis suggests a resonance with a mass of 2.83 GeV as
member of the trajectory from the corresponding Chew-Frautschi
plot.Comment: 12 pages, 16 figure
