The approximately 200,000-mile fuel pipeline system in the U.S. operates at flow rates up to 2.5 x 10 gallons per hour (GPH). Most commercial technologies only provide on-line leak detection at about 0.3% of flow rate, i.e., about 7,500 GPH or larger. Detection of leaks at about 1 GPH or so is desirable both from a regulatory and leak-prevention standpoint. Brookhaven’s commercially-accepted pe...

Secretion of the pituitary glycoprotein hormones (GpH) follitropin, lutropin, and thyrotropin in vertebrates is the main mechanism by which neuroendocrine signals are propagated at the level of the peripheral glands, gonads and thyroid. Receptors of these hormones (glycoprotein hormone receptors, GpH-R) evolved from a common ancestor through gene duplication and subsequent functional divergence...

A full-length transcript encoding a functional lamprey glycoprotein hormone receptor I (lGpH-R I, GenBank AY750688) was cloned from the testes of the sea lamprey, Petromyzon marinus, using the GpH-R protein fingerprint GLYCHORMONER from the PRINTS database. The present study is the first to identify a GpH-R transcript in an agnathan, which is one of the only two representatives of the oldest li...

There are species differences between human histamine H(1) receptor (hH(1)R) and guinea pig (gp) histamine H(1) receptor (gpH(1)R) for phenylhistamines and histaprodifens. Several studies showed participation of the second extracellular loop (E2-loop) in ligand binding for some G protein-coupled receptors (GPCRs). Because there are large species differences in the amino acid sequence between hH...

Background: Self-reports of health provide useful information about function and well-being that can improve communication between patients and clinicians. Global health items provide summary information that are predictive of health care utilization and mortality. There is a need for parsimonious global health scales for use in large sample surveys. This study evaluates the reliability and val...

D-glucose derivatives of dihydropyrido-[2,3-d:6,5-d']-dipyrimidine-2, 4, 6, 8(1H,3H, 5H,7H)-tetraone (GPHs) have been synthesized and investigated as corrosion inhibitors for mild steel in 1M HCl solution using gravimetric, electrochemical, surface, quantum chemical calculations and Monte Carlo simulations methods. The order of inhibition efficiencies is GPH-3 > GPH-2 > GPH-1. The results furth...

Hagfish, which lack both jaws and vertebrae, are considered the most primitive vertebrate known, living or extinct. Hagfish have long been the enigma of vertebrate evolution not only because of their evolutionary position, but also because of our lack of knowledge on fundamental processes. Key elements of the reproductive endocrine system in hagfish have yet to be elucidated. Here, the presence...

Although restricted transhepatic portal flow is necessary for development of generalized portal hypertension (GPH), increased splanchnic arterial inflow also contributes to GPH and its clinical sequelae. In this context, we describe 7 male and 6 female patients (mean age 48 years) in whom the lesser splanchnic (gastrosplenic) system played a key role in the signs and symptoms of GPH. These 13 p...
