Using a screening risk score that measured each boy's antisocial behavior, boys identified at the top 30 percent within each grade sample on the screening risk measure (n=~250), as well as an equal number of boys randomly selected from the remainder (n=~250), were selected for follow-up.

That payload will measure any potential tenuous atmosphere and ionosphere of the main-belt comet, as well as study the interaction between the solar wind and the two small bodies. (space.com)

FSIS currently collects raw beef manufacturing trimmings verification samples using the N60 excision sampling procedure as described in FSIS Directive 10,010.1 , Sampling Verification Activities for Shiga Toxin-Producing Escherichia coli (STEC) in Raw Beef Products . (usda.gov)

Lastly, the authors believe that the time of persistence of viral DNA in body fluids estimated in this study might not be generalizable to all monkeypox infections, especially asymptomatic ones. (news-medical.net)

The viral DNA was the least persistent in skin lesion samples (5.7 days median time). (news-medical.net)

Given the significant breadth of the areas under study, and the limited human and financial resources of the Organization to carry out the full studies, the Secretariat sought external support. (who.int)

A sample of 151 mothers and fathers was used, the majority with education level up to high school and income up to two minimum wages. (bvsalud.org)
Studies suggest that screening is appropriate in infants of mothers who are diabetic, infants who are large or small for their gestational age, and infants who are premature. (medscape.com)
