Knowledge of age as a function of depth in glacial ice is important for both glaciology and paleoclimatology. For sites near a ridge or dome, an ice flow model together with information on accumulation rate provides a first approximation. If the accumulation rate is high enough, annual layering of isotopes and dust measured in a solid core can provide a precise age vs depth relationship. For So...

Type 2 diabetes is associated with increased risks for several cancers, including colon,1 postmenopausal breast,2 pancreatic,3 liver,4 endometrial,5 and bladder6 cancers and non-Hodgkins lymphoma.7 Type 2 diabetes is also linked to a modest decrease in the risk for prostate cancer.8 However, diabetes does not reduce aggressive forms, and prostate cancer mortality rates are higher among men with...

Sir—In response to the letter of Drs. Frederiksen and Tønning [1], we note that ATCC 13361 is used as the standard strain for Pasteurella gallinarum identification. The biological features of the strains of ATCC 13361 and P. gallinarum isolated from our patient were the same. Both types of bacteria were gram-negative rods that were unable to grow on MacConky agar, and neither of them produced i...
