The spaceM of nondegenerate, properly embedded minimal surfaces in R3 with finite total curvature and fixed topology is an analytic lagrangian submanifold of Cn, where n is the number of ends of the surface. In this paper we give two expressions, one integral and the other pointwise, for the second fundamental form of this submanifold. We also consider the compact boundary case, and we show tha...

vestigated in the study by Kim et al. were between 40 and 59 years of age. The overall prevalence of polyps (31.4%) is high in comparison with recent data from Rundle et al. [4] . A possible explanation is the exclusive male population that was studied. Regula et al. [5] have already shown a sex-related difference in polyp prevalence. The prevalence was equivalent in a cohort of men between 40 ...

The study of ideals in polynomial rings over fields is absolutely central to algebraic geometry. We think of an affine variety (usually called affine algebraic set without an irreducibility hypothesis) in n dimensions as defined to be the common zero set of a collection of polynomials f1(x1, . . . , xn), . . . , fm(x1, . . . , xn) with coefficients in some field k. We see that if a point (c1, ....

Nitriles play a key role as molecular precursors in prebiotic experiments based on the RNA-world scenario for origin of life. These chemical compounds could have been partially delivered to young Earth from extraterrestrial objects, stressing importance establishing reservoir nitriles interstellar medium. We report here detection towards cloud G+0.693?0.027 several nitriles, including cyanic ac...

BACKGROUND Charcot neuroarthopathy (CN), a rare foot and ankle condition usually complicating diabetes mellitus, leads to deformity, poor quality of life, and increased mortality and morbidity. The prevalence of this condition in the diabetic patient population is not currently known but has been reportedly misdiagnosed in up to 95% of cases. METHODS We sought to evaluate general knowledge re...

Nitriles have been shown to be effective vibrational probes of local environments in proteins but have yet to be fully utilized for the study of nucleic acids. The potential utility of 5-cyano-2'-deoxyuridine ( 1) as a probe of local nucleic acid environment was investigated by measuring the dependence of the IR nitrile stretching frequency (nu CN), line shape, and absorbance on solvent and tem...

BACKGROUND Congenital nystagmus (CN) is characterized by conjugated, spontaneous, and involuntary ocular oscillations. It is an inherited disease and the most common inheritance pattern is X-linked CN. In this study, our aim is to identify the disease-causing mutation in a large sixth-generation Chinese family with X-linked CN. METHODS It has been reported that mutations in four-point-one, ez...

BACKGROUND Contrast nephropathy (CN) is a common cause of renal dysfunction after cardiac angiography. Recently, N-acetylcysteine (NAC) has been found to reduce the risk of CN after CT imaging with contrast enhancement. The purpose of the current study was to evaluate the efficacy of NAC for the prevention of CN in the setting of cardiac angiography. METHODS Eligible patients were those under...
