Twenty-one populations of the checkerspot butterfly, Euphydryas editha, and ten chalcedona were sampled for genetic variation at eight polymorphic enzyme loci. Both species possessed loci that highly variable from population to virtually identical across all sampled. Our data indicate neutrality hypothesis is untenable studied, therefore selection indicated as major factor responsible producing these patterns. Thorough ecological work allowed gene flow be ruled out (in almost instances) a...

We investigated growth and dispersal of postdiapause Euphydryas editha larvae in a serpentine soil-based grassland, using groups individually marked weighed larvae. Larval weight gain was highly correlated with insolation at ground level which is determined by slope exposure date. Maximum distances were excess 10 m d-l1; greater than 5 d-~ resulted depressed rates during the period dispersal. Larvae disperse such can transfer from cool to warm slopes pupate up two weeks sooner remaining on...

The use of allograft struts and cerclage wire, possibly augmented by plate fixation, for the treatment Vancouver type-B1 peri-prosthetic fractures around a total hip replacement has been strongly advocated.

Background: Patient-reported outcomes are increasingly utilized in routine orthopedic clinical care. Computer adaptive tests (CATs) from the Patient-Reported Outcomes Measurement Information System (PROMIS) offer a brief and precise assessment that is well suited for collection within busy environments. However, software apps support administration scoring of CATs, provide immediate access to patient-reported outcome (PRO) scores, minimize clinician burden not widely available.

Abstract Background Invasive urodynamics is used to investigate the causes of lower urinary tract symptoms; a procedure usually conducted in secondary care by specialist practitioners. No study has yet investigated feasibility carrying out this non-specialist setting. Therefore, aim was explore, using qualitative methodology, and acceptability conducting invasive urodynamic testing primary care. Methods Semi-structured interviews were during pilot phase PriMUS study, which men experiencing...

Fixation of periprosthetic femur fractures around total hip implants without cerclage cables or strut grafts. Periprosthetic stems are challenging because it is difficult to gain proximal fixation in the area femoral stem. The bone often osteoporotic and locking preferred over conventional fixation. Most plates do not have ability angle screws stem still lock into plate. Surgeons resorted use fix plate allograft cortical struts improve strength construct. With advent polyaxial a that wider...
