In 1971-3 data on smoking habits, cigarette brand smoked, morning phlegm production, and lung function were recorded for factory workers as part of the Heart Disease Prevention Project. These men were reassessed in 1984 and those who had always smoked cigarettes from the same tar group were compared with those who had dropped one tar group (mean decreases of 6.6 mg tar, 0.1 mg nicotine) and two...

The intrasynovial flexor tendons of the hand are critical for normal hand function. Injury to these tendons can result in absent finger flexion, and a subsequent loss of overall hand function. The surgical techniques used to repair these tendons have improved in the past few decades, as have the postoperative rehabilitation protocols. In spite of these advances, intrasynovial flexor tendon repa...

The aim of this study was to document and evaluate the early results of a nationwide series of total ankle replacements (TARs) performed using second- and third-generation implants. METHODS Records of total ankle replacements performed between February 2000 and November 2005 were retrieved from the New Z...

We report a novel task designed to elicit transient attention-lapse induced alienation (ALIA) of agency experiences in normal participants. When attention-related action slips occur during the task, participants reported substantially decreased self control as well as a high degree of perceived agency attributed to the errant hand. In addition, participants reported being surprised by, and anno...

p s t m w t n p a g e r t A procedure to calculate probability limits for the inference that the absence of a taxon from a woodrat (Neotoma) midden implies bsence from the paleolandscape uses paired samples of modern egetation communities and paired samples of paleocommunities. ssumptions are: (1) each member of a sample pair is an indeendent measure of the same vegetation assemblage; (2) behav...

The purpose of this study was to investigate the effect of tooth agenesis on dentofacial structures according to the location of the absent teeth. A total of 74 subjects were classified to three main groups and four subgroups according to the location of the absent teeth. Thirteen subjects without tooth agenesis were selected as the control group. All subjects were evaluated cephalometrically. ...
