In many bacteria, LuxS functions as a quorum-sensing molecule synthase. However, it also has a second, more central metabolic function in the activated methyl cycle (AMC), which generates the S-adenosylmethionine required by methyltransferases and recycles the product via methionine. Helicobacter pylori lacks an enzyme catalyzing homocysteine-to-methionine conversion, rendering the AMC incomple...

One is a small, portable printing calculator and the other is a hand-held version without a printer. Both versions feature a "smart" magnetic card reader, and each can run the other's programs. TWO POWERFUL NEW fully programmable per sonal calculators in the tradition of the HP-65 (the first fully programmable pocket-sized scientific calculator)1 are the pocket-sized HP-67, Fig. 1, and the HP-9...

Alzheimer's Disease (AD) is characterized by a stereotypical spatial pattern of hippocampus (HP) atrophy over time, but reliable and precise measurement of localized longitudinal change to individual HP in AD have been elusive. We present a method for quantifying subject-specific spatial patterns of longitudinal HP change that aligns serial HP surface pairs together, cuts slices off the ends of...

OBJECTIVE Haptoglobin (Hp) genotype (Hp 1-1, 1-2, or 2-2) is associated with risk for type 2 diabetes complications, but its relationship with cognitive compromise, a growing concern in type 2 diabetes, has rarely been studied. This study investigated whether Hp genotype is associated with cognitive function in cognitively normal elderly diabetic subjects. RESEARCH DESIGN AND METHODS Relation...

BACKGROUND Total pharyngolaryngoesophagectomy and gastric transposition (TPLEGT) for pharyngoesophageal (PE) tumors may require thyroidectomy (with or without removal of the parathyroid glands) to obtain adequate margins around the tumor. As a result, a considerable number of patients may have hypoparathyroidism (HP) develop. The objective of this article is to report our experience with differ...

BACKGROUND We have recently demonstrated in man that a functional allelic polymorphism in the Haptoglobin (Hp) gene plays a major role in determining survival and congestive heart failure after myocardial infarction (MI). We sought to recapitulate the effect of Hp type on outcomes and cardiac remodeling after MI in transgenic mice. METHODS The Hp 2 allele exists only in man. Wild type C57Bl/6...

Hephaestin (Hp) is a membrane protein with ferroxidase activity that converts Fe(II) to Fe(III) during the absorption of nutritional iron in the gut. Using anti-peptide antibodies to predicted immunogenic regions of rodent Hp, previous immunocytochemical studies in rat, mouse, and human gut tissues localized Hp to the basolateral membranes of the duodenal enterocytes where the Hp was predicted ...

OBJECTIVE Intraplaque hemorrhage increases the risk of plaque rupture and thrombosis. The release of hemoglobin (Hb) from extravasated erythrocytes at the site of hemorrhage leads to iron deposition, which may increase oxidation and inflammation in the atherosclerotic plaque. The haptoglobin (Hp) protein is critical for protection against Hb-induced injury. Two common alleles exist at the Hp lo...
