Rising sea levels and the increase of shoreline wave energy at American Samoa.

American Samoa is experiencing rapid relative sea level rise due to increases in global sea level and significant post-2009 earthquake land subsidence, endangering homes and critical infrastructure. Wave and water-level observations collected over a fringing reef at Faga'itua Bay, American Samoa, in 2017 reveal depth-limited shoreline sea-swell wave heights over the range of conditions sampled. Using field data to calibrate a one-dimensional, phase-resolving nonhydrostatic wave model (SWASH), we examine the influence of water level on wave heights over the reef for a range of current and future sea levels.

Sixteen years of bathymetry and waves at San Diego beaches.

Sustained, quantitative observations of nearshore waves and sand levels are essential for testing beach evolution models, but comprehensive datasets are relatively rare. We document beach profiles and concurrent waves monitored at three southern California beaches during 2001-2016. The beaches include offshore reefs, lagoon mouths, hard substrates, and cobble and sandy (medium-grained) sediments.

Public/private interactions during emergency preparedness situations.

The establishment of person to person communications between first responders in both the public and private sectors in advance of an emergency is essential to avoid a catastrophic outcome, according to the author, a member of the Homeland Security Unit of the Chicago. IL, Police Department. He stresses that 85 % of the country's critical infrastructure is protected by private security.

Weak substrate binding to transport proteins studied by NMR.

The weak binding of sugar substrates fails to induce any quantifiable physical changes in the L-fucose-H+ symport protein, FucP, from Escherichia coli, and this protein lacks any strongly binding ligands for competitive binding assays. Access to substrate binding behavior is however possible using NMR methods which rely on substrate immobiliza-tion for detection. Cross-polarization from proton to carbon spins could detect the portion of 13C-labeled substrate associated with 0.

Absorption of doxycycline from a controlled release pellet formulation: the influence of food on bioavailability.

A three-way crossover study was performed to compare the bioavailability of a new pelletised doxycycline product administered either with food or without food and a reference product taken without food. Four different methods were used to calculate pharmacokinetic parameters from the data. The sums of squares, Akaike's Information Criterion (AIC), and the ranges for the parameters obtained were used for comparison.

Obstetric outcomes at the birth place in Menlo Park: the first seven years.

During its first seven years of operation, the Birth Place, a free-standing birth center in California, registered 898 women, of whom 690 (77%) were admitted in labor and 150 (17%) were referred for hospital birth prior to onset of labor. Using carefully delineated screening criteria, the center had an overall 18% intrapartum transport rate to the hospital, primarily for prolonged or arrested labor, a 3% cesarean section rate, no maternal mortality, and one neonatal death resulting from Cornelia de Lange syndrome, a congenital mental retardation-malformation syndrome of unknown etiology, which in this case was incompatible with life. Deliveries at the Birth Place were associated with low cost, a high level of maternal satisfaction, a low cesarean section rate, low neonatal mortality, and no maternal mortality.

Intensive induction treatment of small cell bronchogenic carcinoma with cyclophosphamide, methotrexate, and etoposide.

Fifty-six patients with histologically confirmed small cell bronchogenic carcinoma were treated with cyclophosphamide, methotrexate, and etoposide. While methotrexate doses were modified for mucositis during the 6-week induction period, none of the drug doses were modified for hematologic toxicity. The overall response rate was 66%, with 16% complete remissions; median survival duration was 28 weeks.

Hairy-cell leukemia associated with Hodgkin's disease: a case report.

A 56-year-old man who had easy bruising, an enlarged left supraclavicular lymph node, and splenomegaly was diagnosed as having hairy-cell leukemia. Treatment consisted of splenectomy. Because of progressive lymphadenopathy in the following months, the patient required reevaluation.

Determination of the acetylator phenotype and pharmacokinetics of some sulphonamides in man.

The pharmacokinetics of sulphamethizole, sulphamethoxazole, sulphadiazine, sulphapyridine and sulphadimidine have been studied in man. Renal clearance values of the metabolite N4-acetylsulphonamide are 6 to 20 times higher than those of the corresponding parent compound. The renal clearance of sulphonamides is dependent on the urine flow.

Pharmacokinetics of N1-acetyl- and N4-acetylsulphamethoxazole in man.

The pharmacokinetics of N1-acetylsulphamethoxazole and N4-acetylsulphamethoxazole in man are described. N1-Acetylsulphamethoxazole is deacetylated to sulphamethoxazole and acetylated to N4-acetylsulphamethoxazole. N4-Acetylsulphamethoxazole is excreted almost unchanged in the urine.

Hexobarbital pharmacokinetics in rats after ligation of the common bile duct.

Rats, with and without bile duct ligation (BDL), were injected with hexobarbital (i.p. and i.

Bioavailability of phenytoin from various pharmaceutical preparations in children.

In children, the blood level of phenytoin was found to be significantly higher when 100 mg capsules rather than 100 mg tablets were administered. When, on the other hand, 30 mg capsules and tablets were compared; the situation was reversed; tablets produced significantly higher blood levels of phenytoin than did the capsules. The significance and possible explantation of these findings are discussed.

Plasma phenytoin levels produced by various phenytoin preparations.

A cross-over study was conducted to compare the plasma phenytoin levels produced by different phenytoin preparations available in Australia. The preparations were found not to be equivalent, a liquid suspension product producing higher levels compared with capsule and tablet formulations. The clinical significance and possible explantation are discussed.

Pharmacokinetic model for the successive demethylation and biliary secretion of methyl orange in the rat.

1. A one-compartment pharmacokinetic model was developed in which a drug underwent two successive metabolical reactions (for example, metabolism followed by conjugation) and free drug and both metabolites were excreted.2.

Magnetic properties of lunar samples.

The magnetic properties of samples of rock, fines, and magnetic separate from the fines from Apollo 11 have been measured. Native iron, or possibly nickel-iron, of submicroscopic particle size is the most important constituent, with minor contributions from ilmenite, paramagnetic iron minerals, and other iron-titanium oxides. The remanent magnetization of a sample of the micro-breccia rapidly acquires a viscous magnetization and does not appear to have a significant stable remanence.
