Nox2 Inhibition Regulates Stress Response and Mitigates Skeletal Muscle Fiber Atrophy during Simulated Microgravity.

Insufficient stress response and elevated oxidative stress can contribute to skeletal muscle atrophy during mechanical unloading (e.g., spaceflight and bedrest).

Bioaerosol emissions from a suburban yard waste composting facility.

The purpose of this study was to assess worker and community exposure to bioaerosols emitted from a suburban yard waste composting facility in northern Illinois, USA. Characterization of on- and off-site viable bioaerosols was undertaken through a total of 288 on- and off-site Andersen samples conducted over 10 sampling days. A total of 46 dust samples and 38 Kramer-Collins spore samples were also collected in this period.

Medical outcome of cocaine bodystuffers.

To describe the clinical course of cocaine "bodystuffers" presenting to regional emergency departments, a descriptive retrospective analysis was performed on all cases of cocaine bodystuffers received by a metropolitan poison control center and associated toxicology service from January 1993 to May 1994. We identified 46 cases of patients classified as bodystuffers. Of these, 34 patients (74%) remained asymptomatic.

Late increase in acetaminophen concentration after overdose of Tylenol Extended Relief.

We report a case demonstrating a late increase in acetaminophen concentration after ingestion of Tylenol Extended Relief (extended-release acetaminophen; McNeil Consumer Products) along with drugs known to slow gastrointestinal motility. Coingestants that slow gastrointestinal motility are known to affect the interpretation of serum drug concentrations. However, this case illustrates potentially significant differences between extended-release and immediate-release acetaminophen and demonstrates an exception to the current manufacturer recommendation for the use of the Rumack-Matthew nomogram in this setting.

Toxicology screening in urban trauma patients: drug prevalence and its relationship to trauma severity and management.

Although toxicology screening is often used when treating trauma patients, its utility and significance remain controversial. Data from 623 toxicology screens performed in urban trauma center patients with mental status alterations are reported. The study patients were predominantly black and male, with a mean age of 32 (+/- 22) years.
