Considerable interest has developed recently in naturally occurring phosphatides containing ether groups. Two classes of ether-containing phosphatides can be envisaged, i.e. monoether, monoester phosphatides, and diether phosphatides. To date, t,he only monoether, monoester phosphatides known to occur naturally are analogues of phosphatidylethanolamine (1-4) and phosphatidylcholine (5, 6). A ch...

The role, of microbial agents and the infection of the intestinal mucosa in the carcinogenesis, or the development of colorectal cancer (CRC) is one of the hot topics in the field of CRC where much research has been done. However, this topic has long been underestimated by most of the related books. This chapter is intended to cover the relationship of CRC development with bacteria implicated i...

An n-dimensional lattice is the set of all integral linear combinations of n linearly independent vectors in R m. One of the most studied algorithmic problems on lattices is the shortest vector problem (SVP): given a lattice, nd the shortest non-zero vector in it. We prove that the shortest vector problem is NP-hard (for randomized reductions) to approximate within some constant factor greater ...

In developed countries heart disease is the primary cause of death in men and in women over the age of 60. While premenopausal women have a low incidence of cardiovascular disease as compared to men, the mortality among post-menopausal women rises to the same frequency or even exceeds the rates of men (Adams et al., 1995; Fraser et al., 2000; Gray et al., 2001; Wild & Bartholemew, 1988). This s...

There is evidence that significant changes may take place in the activities ofenzymes present in secreting glands under the influence of regulatory hormones. Gutman & Gutman (1938) reported increases in the acid phosphatase activity of prostate during the development of the epithelia induced by testosterone. According to Fuenzalida (1949), prolonged oestrogen treatment causes an increase in alk...

December 2009 JOURNAL OF ADVERTISING RESEARCH 419 measure their success through user-response metrics such as click-through rate (CTR), conversion rate (Richardson, Dominowski, and Ragno, 2007), and bounce rate (Sculley, Malkin, Basu, and Bayardo, 2009), Google has been exploring how to use STB measurement to design equivalent measures for TV. Past attempts to provide quality scores for TV ads ...

Nuclear magnetic resonance (NMR) spectroscopy analyzes the magnetic properties of an active nucleus for physical and chemical determination. Important information about chemical bonding and molecular structure are provided by chemical shifts (δ) and spin-spin coupling parameters.[1,2] The chemical shift (δ) trends for halogen (X) in different nuclei (Te, C, La, P, etc.) have been investigated e...

Generally, high testosterone levels within the physiological range are associated with a more favourable cardiometa-bolic profile. Although the FDA has approved testosterone for use only in men with hypogonadism, whose sex glands produce extremely low amounts of testosterone, off-label use has dramatically increased in recent years. In the past two decades, there has been a huge increase in tes...

We examined loss of heterozygosity (LOH) for two loci on chromosome 17p (D17S5 and TP53), and erbB-2 gene amplification, in primary breast cancers from 67 Brazilian patients. We identified two distinct regions of LOH on chromosome 17p, one spanning TP53 and the other a more telomeric region (D17S5). Based on a short-term follow-up, Kaplan-Meier analyses of patients' disease-free survival showed...
