In the Alpha Omega Trial, we observed that an additional amount of n-3 fatty acids significantly reduced the number of ventricular arrhythmia–related events and fatal myocardial infarctions (MIs) in post-MI patients with diabetes (1). In their letter, Giordani et al. (2) suggest that an abnormal cardiac repolarization, due to an imbalance of the autonomic nervous system, could be the link betwe...

Radiative transfer is a phenomenon that has importance in a wide range of applications from climatology to astrophysics. Depending on the physical regimes involved, a hierarchy of models may be used, each of which having drawbacks and qualities. However, there are still applications for which no model is fully satisfying. An example is ICF (Inertial Confinement Fusion) where dozens of lasers co...

Objective. To determine the most costeffective treatment for phimosis. Design. The costs of three treatment strategies for treating phimosis were evaluated using a decision-tree analysis. Three therapeutic approaches were considered: circumcision, preputial plasty (the use of plastic surgical techniques to enlarge the preputial opening without removing tissue), and topical therapy with steroids...

Maize (Zea mays L.) germplasm exhibits large genetic variations in tolerance to high temperature (HT) stress under fi eld conditions, but the mechanisms underling this variation are largely unknown. Based on many years of fi eld observation, maize inbred line B76 consistently displays better tolerance to HT than B106. Heat waves during growing season cause leaf fi ring in developing leaves and ...

EDITOR—Germline mutations in the BRCA1 and BRCA2 genes are associated with an increased risk of breast and ovarian cancer. DiVerent patient populations, predominantly with at least some familial aggregation of breast/ ovarian cancer, have been screened to estimate the frequency of mutations and identify women for whom mutation analysis should be considered. The prevalence of BRCA1 and BRCA2 gen...

We investigated the community structure of Synechococcus and Prochlorococcus along a transect in the Arabian Sea during September 2001. The transect spanned contrasting oceanic conditions, allowing investigation of the effects of both horizontal and vertical environmental gradients over relatively large spatial scales on picocyanobacterial population structure. We applied previously developed o...

The correlation between decreased morbidity and mortality of cancer and exposure to sunlight is known. The many biological functions of vitamin D that contribute to cancer prevention have only recently begun to be appreciated. Once activated 1,25-dihydroxyvitamin D [1,25(OH)2D3] functions as a potent inhibitor of normal and cancer cellular proliferation. Vitamin D deficiency in mice led to a 60...

Background: Sjögren’s syndrome (SS) is a chronic, systemic autoimmune disorder characterised by oral and ocular dryness related to lymphocytic infiltration of exocrine glands. 1–3 Extra-glandular manifestations may include fatigue, musculoskeletal pain glomerulonephritis. 1,3 SS can present as primary (pSS) or associated with another (SS+AID). 1 Reported prevalence pSS in the French general pop...

High molecular weight components from Ascaris suum extract suppress ovalbumin-specific immunity in mice. In IFN-γ-deficient mice, ovalbuminspecific delayed-type hypersensitivity reactions are more strongly downregulated by these suppressive components. Here, the cellularity of the delayed-type hypersensitivity reaction in IFN-γ-deficient mice and the increased downregulation induced by Ascaris ...
