miR-29a is a negative regulator of influenza virus infection through targeting of the frizzled 5 receptor.

Influenza A virus (IAV) infections result in a large number of deaths and substantial economic losses each year. MicroRNAs repress gene expression and are involved in virus-host interactions. miR-29a is known to have anti-tumor and anti-fibrotic effects.

Factors influencing attrition in a multisite, randomized, clinical trial following traumatic brain injury in adolescence.

Background: Attrition in longitudinal research negatively affects statistical power, disrupts statistical stability, and can produce unwanted bias.

Objective: To investigate factors associated with shorter length of study participation and lower rates of study completion (ie, attrition) in a large, multisite, longitudinal, randomized, clinical trial examining the efficacy of a Web-based family problem-solving treatment following traumatic brain injury (TBI) in adolescence.

Setting: Five major trauma centers in the central and western regions of the United States.

Noncredible effort during pediatric neuropsychological exam: a case series and literature review.

Neuropsychological test interpretation rests upon the assumption that the examinee has exerted full effort. If an individual provides inadequate effort during exam, the resulting data will be invalid and represent an underestimate of the person's true abilities. Although youth have been assumed historically to be less capable of deception than adults, acts of deception in childhood are not uncommon, even in normative populations.

Leaching of diethylhexyl phthalate from polyvinyl chloride bags into intravenous cyclosporine solution.

The release of diethylhexyl phthalate (DEHP) from flexible polyvinyl chloride containers into intravenous cyclosporine solutions was studied. Intravenous cyclosporine solution or solutions containing the vehicle Cremophor EL and alcohol in dextrose were prepared in an all-glass system and stored in polyvinyl chloride (PVC) bags. Four samples were obtained at different time intervals, and DEHP content was analyzed by gas chromatography.

Immunological surveys of diphtheric antitoxic antibodies in some African and Asian countries.

Immunological surveys of diphtheric antitoxic antibodies confirmed the existence of a high circulation of Corynebacterium diphtheriae in some African and Asian countries. The high immunity level in early childhood confirms the well known fact that other forms of diphtheria, in particular the cutaneous forms, participate in the formation of antitoxic antibodies. Immunological surveys can determine relatively exactly the extent of risk of infection in the separate age groups and thus delimit the range of the planned vaccination campaigns.

Enterotoxigenic E. coli in humans.

E. coli strains isolated from persons having diarrhoeal disease were tested for the production of TS enterotoxin. The production of TSE was demonstrated in 2.
