Complete genome sequence of strain H905, a planktonic isolate among squid symbiotic congeners.

Here we describe the genome sequence of () H905, a non-symbiotic isolate from Kaneohe Bay, Hawaii. Despite its close phylogenetic relationship to squid symbiont strains, H905 is not adept at colonization. Its genome serves as a valuable comparator, illustrating the complex evolutionary dynamics within clades.

Diazotroph diversity and nitrogen fixation in the coral Stylophora pistillata from the Great Barrier Reef.

Diazotrophs, both Bacteria and Archaea, capable of fixing nitrogen (N), are present in the tissues and mucous, of corals and can supplement the coral holobiont nitrogen budget with fixed nitrogen (N) in the form of ammonia (NH). Stylophora pistillata from Heron Island on the Great Barrier Reef collected at 5 and 15 m, and experimentally manipulated in the laboratory, showed that the rates of net photosynthesis, steady state quantum yields of photosystem II (PSII) fluorescence (∆F/F') and calcification varied based on irradiance as expected. Rates of N fixation were, however, invariant across treatments while the amount of fixed N contributing to Symbiodinium spp.

HEALS: A Faith-Based Hypertension Control and Prevention Program for African American Churches: Training of Church Leaders as Program Interventionists.

Background. A 12-session church-based HEALS program (healthy eating and living spiritually) was developed for hypertension control and prevention program in African Americans (AAs). This study presents specifics of training lay health educators to effectively deliver HEALS to high-risk AAs.

A pilot clinical trial of varenicline for smoking cessation in black smokers.

Introduction: Varenicline, a first-line non-nicotine medication, has not been evaluated in Black smokers, and limited attention has been paid to pharmacotherapy adherence in smoking cessation trials. This pilot study estimated quit rates for Black smokers treated with varenicline and tested a behavioral intervention to aid varenicline adherence.

Methods: Seventy-two Black smokers (>10 cigarettes per day; cpd) were randomly assigned to adherence support (AS; n = 36) or standard care (n = 36).

School nurses' perceived barriers to discussing weight with children and their families: a qualitative approach.

Background: Previous studies have documented the presence of specific barriers to school nurses' communications with families about weight-related health. The purpose of the present study was to contribute to the literature by further analyzing, using focus group methodology, school nurses' perceived barriers to addressing weight-related health issues with children and their families.

Methods: Twenty-two school nurses from urban and rural school districts in the Midwestern United States participated in 7 focus groups during the spring semester of 2008.
