BACKGROUND There are limited contemporary data comparing long-term outcomes after cardiac catheterization for ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI). METHODS AND RESULTS We studied patients undergoing cardiac catheterization for STEMI (n=2413) and NSTEMI (n=1974) between 1999 and 2005 with at least 1 significant coronary lesion > or =75%. We compared adjuste...

Maternal vitamin status contributes to clinical spontaneous abortion, but the role of B-vitamin and homocysteine status in subclinical early pregnancy loss is unknown. Three-hundred sixty-four textile workers from Anqing, China, who conceived at least once during prospective observation (1996-1998), provided daily urine specimens for up to 1 year, and urinary human chorionic gonadotropin was as...

Nine hundred fifty-one emergency and 997 nonemergency patients seeking endodontic treatment were the basis of this study. Variables of interest were 10 pain descriptors, percussion and palpation tests, causative factors, and paired pulpal and periapical diagnoses. A higher number of patients suffering from symptomatic pulpal conditions sought emergency care. Odds of caries being a causative fac...

A sequence of positive integers w1, w2, . . . , wn is called an ascending wave if wi+1 − wi ≥ wi − wi−1 for 2 ≤ i ≤ n − 1. For integers k, r ≥ 1, let AW (k; r) be the least positive integer such that under any r-coloring of [1, AW (k; r)] there exists a k-term monochromatic ascending wave. The existence of AW (k; r) is guaranteed by van der Waerden’s theorem on arithmetic progressions since an ...

Frequent sub-graph mining entails two significant overheads. The first is concerned with candidate set generation. The second with isomorphism checking. These are also issues with respect to other forms of frequent pattern mining but are exacerbated in the context of frequent sub-graph mining. To reduced the search space, and address these twin overheads, a weighted approach to sub-graph mining...

The conjoint influence of welding and artificial aging on mechanical properties were investigated for extrusions of aluminum alloy 6063, 6061, and 6005A. Uniaxial tensile tests were conducted on the aluminum alloys 6063-T4, 6061-T4, and 6005A-T1 in both the as-received (AR) and as-welded (AW) conditions. Tensile tests were also conducted on the AR and AW alloys, subsequent to artificial aging. ...

BACKGROUND Numerous studies have compared the outcomes of two competing interventions for multivessel coronary artery disease: coronary-artery bypass grafting (CABG) and coronary stenting. However, little information has become available since the introduction of drug-eluting stents. METHODS We identified patients with multivessel disease who received drug-eluting stents or underwent CABG in ...

The acoustic glitches' signature present in solar-like stars holds invaluable information. Indeed, it is caused by a sharp variation the sound speed, therefore carrying localised One such glitch helium hydrogen and first second partial ionisation region, allowing us to constrain surface abundance. However, function adjusted depends non-linearly on depth at which occurs, He. Retrieving faint est...
