ABSTRACT

Rod-like bolapolyphiles with highly branched carbosilane-based side-chains self-assemble into several honeycomb structures if the oligo(p-phenylene ethynylene) core is polyfluorinated, whereas for the non-fluorinated series an A15 type cubic network of rod-bundles was observed instead, suggesting a brand new pathway for the transition between triangular and square honeycomb phases.

ABSTRACT

OBJECTIVE: To determine whether application of a commercially available static magnetic field would alter the signs and/or symptoms of delayed onset muscle soreness (DOMS) produced by exhaustive eccentric exercise. DESIGN: A double-blinded, randomized, and placebo-controlled study, with subjects serving as their own controls. SETTING: An outpatient physical therapy and performance center. PARTICIPANTS: Twenty-three healthy volunteers (18 women; mean age, 30 y; range, 18-40 y; 5 men; mean age, 29 y; range, 19-39 y). INTERVENTION: After exhaustive eccentric exercise of both the right and left elbow flexor muscle groups, subjects received daily treatment with either a 350G magnet or a placebo device for 5 consecutive days. MAIN OUTCOME MEASURES: Outcome variables, including anthropometric measurements, perceived discomfort, and muscle force production, were compared using linear mixed models. RESULTS: Arm circumference, relaxed elbow flexion angle, and pain increased, whereas active elbow flexion angle and maximal isometric torque decreased transiently before returning to near baseline. No significant difference in outcome variables existed between the treated and control arms. Participants reported less pain in both treated and control arms after each session, suggesting a placebo effect. CONCLUSIONS: Static magnetic fields were no more effective than placebo in preventing DOMS.

ABSTRACT

BACKGROUND: No reliable statistics exist for injury rates among occasional woodcutters as opposed to professional loggers. Study objectives were to assess woodcutting injuries seen in emergency rooms and identify risk factors. METHODS: Individuals with woodcutting related injuries were identified in 14 emergency and urgent care departments in central and northern Wisconsin. A telephone survey was conducted within 3 weeks of presentation to determine number and types of injuries, causes, and characteristics of the injured. RESULTS: Three times as many woodcutting-related injuries occurred in non-logger survey participants (54 vs. 17). There was no significant difference in age or type of injury. Loggers were more likely to wear personal protective equipment. Younger individuals attributed their accidents to human errors, whereas older individuals felt their injuries were unavoidable. CONCLUSIONS: Occasional woodcutting activities result in comparable, but more frequent injuries than professional logging activities. Further data are needed to assess impact on public safety.

ABSTRACT

The project goal was to collaborate with veterinarians in delivering skin cancer information to a farming population. Two interventions and a control were utilized: in nine Wisconsin counties veterinarians delivered education materials as part of routine dairy herd health visits, veterinarians in nine additional counties provided client lists so education materials could be mailed, and veterinarians in nine control counties provided client lists but farmers received no education materials. A questionnaire was administered by phone to a random sample of farmers in each group, assessing knowledge, sun protection attitudes and behaviors, acceptance of veterinarians in a human health education role. Farmers responded quite favorably to veterinarians in this role. Veterinarians can be regarded as useful agents to disseminate health information to isolated rural populations.
