Lingual markings of anterior teeth as seen in human bite marks

A review of the available literature does not reveal a plausible explanation as to why the incisal edges of maxillary anterior teeth do not always mark clearly. Generally, the mandibular incisal edges do mark with some consistency. This paper demonstrates through test bites on skin that the answer lies in the position of the mandible.     

Pete Maravich's incredible heart

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding.

Comparison of fingernail striation patterns in identical twins.

The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images.     

Responding to the global tobacco industry: Canada and the Framework Convention on Tobacco Control

Abstract: In a continuing quest to build and defend world markets for tobacco products, tobacco companies have long been involved in international cooperation and information‐sharing through their own international corporate networks, as well as through national and international industry trade associations. This is evidenced in tobacco industry corporate documents now freely available on the internet. In order to institute effective tobacco control policy, policy‐makers needed to become equally astute at sharing information across national boundaries and at considering the cross‐national implications of policy and legislation. The World Health Organization has been instrumental in developing the Framework Convention on Tobacco Control (FCTC), and Canada has played an important part in this effort. The FCTC contains both demand‐reduction provisions and supply‐side provisions intended to reduce tobacco use worldwide. As a signatory to the FCTC, Canada has pledged to adhere to these provisions, thereby providing Canadian public administrators with effective tools to reduce tobacco use and its associated health burden both nationally and internationally. Sommaire: En cherchant continuellement à développer et à défendre les marchés mondiaux pour les produits du tabac, les sociétés productrices de tabac sont impliquées depuis longtemps dans la coopération internationale et le partage d'informations par le biais de leurs propres réseaux de sociétés internationales et d'associations professionnelles nationales et internationales. C'est ce qui ressort des documents des sociétés productrices de tabac auxquels on peut accéder librement sur Internet. Afin d'instituer une politique efficace de contrôle du tabagisme, les décideurs politiques ont dù devenir astucieux quant au partage d'informations et à l'étude des répercussions transnationales des politiques et des lois. L'Organisation mondiale de la santé a fortement contribuéà l'élaboration de la Convention‐cadre sur la lutte contre le tabagisme (CCLCT), et le Canada a joué un rôle important sur ce plan. La CCLCT contient à la fois des dispositions relatives à la réduction de la demande et d'autres relatives à l'offre qui visent à réduire la consommation de tabac dans le monde entier. En tant que pays signataire de la CCLCT, le Canada s'est engagéà respecter ces dispositions, fournissant ainsi aux administrateurs publics canadiens des outils efficaces pour réduire la consommation de tabac et le fardeau sur la santé qui lui est associéà l'échelle nationale et internationale.
