Sir—We were made aware of the interesting research conducted by Sibai et al. during our literature review. In their casecontrol study they investigated the relation of war stressors to coronary artery disease (CAD) as determined by coronary angiography and in their cohort study war exposures were studied with reference to CVD mortality. We find it difficult to compare their research with ours d...
Selenium deficiency has been suggested by several studies to be associated with cancer risk. We conducted a casecontrol study in Szczecin, a region of northwestern Poland, on 86 cases of lung cancer, 87 cases of laryngeal cancer and an equal number of healthy controls. We studied the serum level of selenium and genotypes for four variants in four selenoprotein genes (GPX1, GPX4, TXNRD2 and SEP1...

This reduction suggested a decrease in the circulation time of used needles among injectors who use the exchange, and this decrease can in t...

The peroxisome proliferator–activated receptor ; (PPAR;) is one of a group of ligand-activated nuclear receptors responsible for regulation of glucose, lipid homeostasis, cell differentiation, and apoptosis. The 12 proline-to-alanine (Pro12Ala) substitution polymorphism in PPARg produces proteins with lower activity. Variation in PPARg expression in the bowel and the role of dietary fatty acids...
were reported in 1954 by Homans (1), interest has recently heightened. Numerous cases have been reported, but controlled studies are few and contradictory. In a series of patients who had died suddenly at Heathrow Airport, this occurred far more often in the arrival than in the departure area (2). Casecontrol studies have yielded conflicting results, with two French studies showing a two to fou...
