A gold standard for the correct rotation of the tibial component has not been established in total knee arthroplasty (TKA). The target parameter of correct rotation is the facilitation of femorotibial rotation over the entire range of motion with no implant overhang. Although the origin of the lateral collateral ligament is a recognized landmark for determining the rotation of the femoral compo...

BACKGROUND Pulling the long head of the biceps tendon into the joint at arthroscopy is a common method for evaluation of tendinopathic lesions. However, the rate of missed diagnoses when using this technique is reported to be as high as 30% to 50%. HYPOTHESIS Tendon excursion achieved using a standard arthroscopic probe does not allow adequate visualization of extra-articular sites of predile...

Fish larvae, like most adult fish, undulate their bodies to propel themselves. A detailed kinematic study of the larval body wave is a prerequisite to formulate a set of functional requirements that the locomotor system must fulfil to generate the observed swimming kinematics. Lateral displacement and curvature profiles were obtained for zebrafish (Danio rerio) larvae at 2-21 days post-fertilis...

Psaroniocompsa incrustata (Lutz) is an antropophilic species widely distributed in Central and South America. It is the vector of Onchocerca volvulus in a Brazilian focus and has been considered a plague in several areas of this country. The objective of this study was to determine the number of larval instars and to describe the morphological variations and teratologies of a population of P. i...

The present study investigated the consistency of the head-turning bias in kissing. In particular we addressed what happens if a person who prefers to kiss with the head turned to the right kisses a person who prefers to kiss with the head turned to the left. To this end, participants (N=57) were required to kiss a life-sized doll's head rotated in different orientations that were either compat...

Hemicriconemoides scottolamassesei n. sp., named after Dr. C. Scotto la Massese, from New Caledonia, is described and illustrated. Primary diagnostic characters are females with a continuous head and three lip annules, the first annule being the smallest, stylet length of 65-75 mum, vulva without lateral flaps, and acute tail terminus; J4 has a smooth cuticle without scales or spines; the male ...

We reviewed the short-term outcome of 171 patients treated with total hip replacement for femoral neck fractures using the lateral (94 patients) or posterior approach (77 patients). The Sernbo score and the Abbreviated Mental Test Score were used to assess patients' pre-injury functional and cognitive status respectively. Patients were uniformly treated with regard to the type of prosthesis, si...
