We report the twining handedness of Codonopsis pilosula, which has either a 9 leftor right-handed helix among different plants, among different tillers within a 10 single plant, and among different branches within a single tiller. The handedness was 11 randomly distributed among different plants, among the tillers within the same plants, 12 but not among the branches within the same tillers. Mo...

Right hemisphere language dominance is rare in right-handed individuals and usually the result of language transfer associated with early left hemisphere pathology. We studied a 33-year-old right-handed man, with a normal MRI scan, who developed left frontal lobe seizures at age 15 years. Language lateralization testing by intracarotid amobarbital injection and dichotic listening showed the pat...

Existing laparoscopic box trainers consist only of static tasks and do not adequately prepare surgeons to navigate the dynamic surgical environment. This paper describes an innovative design using controlled motorized target movements to enhance the training of dynamic motor skills. The prototype was tested using 15 subjects with different surgical experience levels. The task required accurate ...

Well-trained experts in pearl grading have been thought to evaluate pearls according to their glossiness, interference color, and shape. However, the characteristics of their evaluations are not fully understood. Using pearl grading experiments, we investigate the consistency of novice (i.e., without knowledge of pearl grading) and expert participants' pearl grading skill and then compare the n...

The purpose of this study was to compare endurance time and accompanying neuromuscular adjustments when left- and right-handed subjects used the dominant and nondominant arms to sustain submaximal contractions that required either force or position control. Ten left-handed and 10 right-handed healthy adults (21 ± 5 yr) participated in the study. Each subject exerted a similar net torque about t...

Fraternal birth order (FBO) appears as a prenatal cause of 15% of homosexual males (gays) through mnemonic maternal anti-male factors. Non-right-handed men seem to be protected from homosexuality. Four hypotheses are proposed: (1) androgenic factors of non-right-handedness neutralize anti-male factors; (2) non-right-handedness and homosexuality are lethal or produce mental impairment; (3) non-r...

Research on the extent and nature of commonly misunderstood fundamental biomedical concepts across a medical curriculum is scarce. These misunderstandings could point toward robust misconceptions. We examined first whether common persist throughout curriculum, followed by fine-grained analysis to identify their nature. designed administered 2-tier test 987 students our with 8 questions covering...

OBJECTIVE There is no ambiguity when a patient presents their medications in the correct packaging during a consultation and declares, "this is what I am taking, doctor, I take this many, at this time". The aim of this study was to establish the prevalence of consultations in which patients attend both "empty handed" and unsure of their treatment. A re-evaluation was made after a simple interve...
