BACKGROUND Reduced mouth opening may be a major contributing factor to the deterioration in the view obtained at laryngoscopy when a semi-rigid cervical collar is in place. We set out to assess the degree to which mouth opening is restricted by a cervical collar. METHODS We measured maximal inter-incisor distance in 52 volunteers. It was measured again after application of each of three appro...

OBJECTIVES To examine demographic and substance use factors associated with exclusive smokeless tobacco use (SLT) and dual use of both cigarettes and SLT among blue-collar workers. DESIGN AND SAMPLE This cross-sectional study used data from the United States 2009 National Survey on Drug Use and Health. The sample (n = 5,392) was restricted to respondents who were classified as blue collar wor...

The echinostome metacercariae encysted in Cipangopaludina sp. snails that were purchased from a market in Vientiane Municipality, Lao PDR, were identified as Echinostoma macrorchis (Digenea: Echinostomatidae) through recovery of adult flukes after experimental infection to rats and a cat. The metacercariae were round, 113-128 (121)×113-125 (120) µm, having a thick cyst wall, a head collar armed...

People generally possess a strong desire to construct positive, dignified work identities. However, this goal may be more challenging for some people, such as blue-collar workers, whose occupations may not offer qualities typically associated with workplace dignity. Interviews with 37 people from a blue-collar mining community reveal three central identity discourses about workplace dignity: Al...

The toxic sheep collar is the most selective method known for killing coyotes that prey on domestic sheep. The concept dates back to the early 1900's, and has been studied at the Denver Wildlife Research Center (DWRC) since 1974. Field tests with sodium cyanide (NaCN) in 1975 were unsuccessful due to repellent properties of the toxicant and to the apparent reluctance of coyotes to attack tether...

BACKGROUND Cervical collar brace protection of the cervical spine at the scene of the incident is the first priority for emergency medical technicians treating patients who have sustained trauma. However, there is still controversy between over- or underprotection. The objective of this study was to survey the cervical spine injury of lightweight motorcycle accident victims and further evaluate...

INTRODUCTION In blunt trauma, comatose patients (Glasgow Coma Scale score 3 to 8) with a negative comprehensive cervical spine (CS) computed tomography assessment and no apparent spinal deficit, CS clearance strategies (magnetic resonance imaging [MRI] and prolonged cervical collar use) are controversial. METHODS We conducted a literature review to delineate risks for coma, CS instability, pr...

This study examined the degree to which blueversus white-collar workers differentially conceptualize various job facets, namely the work itself, co-workers, supervisors, and pay. To examine these potential differences, we conducted a series of analyses on job satisfaction ratings from two samples of university workers. Consistent with the study hypothesis, results revealed that blueand white-co...

The flagellar pocket is a bulb-like invagination of the plasma membrane that encloses the base of the single flagellum in trypanosomes. It is the site of all endo- and exocytic activity in the parasite and has thus been proposed to be a therapeutic target. At the neck of the flagellar pocket is an electron-dense cytoskeletal structure named the flagellar pocket collar. The protein BILBO1 was th...
