Todos os Santos Bay (BTS) is the 2nd largest bay in Brazil and an important resource for the people of the State of Bahia. We made measurements of radon and radium in selected areas of the bay to evaluate if these tracers could provide estimates of submarine groundwater discharge (SGD) and flushing times of the Paraguaçu Estuary and BTS. We found that there were a few areas along the eastern and northeastern shorelines that displayed relatively high radon and low salinities, indicating possible sites of enhanced SGD...

OBJECTIVE: The objective of this study was to explore the types of patient safety events that take place during pediatric out-of-hospital cardiac arrest resuscitation. METHODS: Retrospective medical record review from a single large urban EMS system of EMS-treated pediatric (<18years of age) out-of-hospital cardiac arrests (OHCA) occurring between 2008 and 2011. A chart review tool was developed for this project and each chart was reviewed by a multidisciplinary review panel...

A Gram-stain-negative, non-motile, aerobic and ovoid or rod-shaped bacterium, designated SCTF-16T, was isolated from a tidal flat on the Yellow Sea, South Korea. Strain SCTF-16T grew optimally at 30 °C, at pH 7.0-7.5 and in the presence of 2.0 % (w/v) NaCl. In the neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences, strain SCTF-16T clustered with the type strains of two species of the genus Umboniibacter. Strain SCTF-16T exhibited 16S rRNA gene sequence similarities of 99...

A Gram-stain-negative, aerobic, non-spore-forming, motile and ovoid or rod-shaped bacterial strain, JDTF-113T, was isolated from a tidal flat in Jindo, an island of South Korea. Strain JDTF-113T grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 2.0 % (w/v) NaCl. A neighbour-joining phylogenetic tree, based on 16S rRNA gene sequences, revealed that strain JDTF-113T fell within the clade enclosing the type strains of species of the genus Alteromonas. Strain JDTF-113T exhibited 16S rRNA gene sequence similarity values of 97...

Americans are suffering from a culture of taking pills. Six out of ten Americans utilize at least one prescription drug, and more than one in ten use five or more prescription medicines. Although this torrent of taking pills is already high, drug use in the USA has not yet crested. Prescription drugs have specific targets, but often they adversely affect other tissues and organs. In keeping with the mission of the recently named National Center for Complementary and Integrative Health (NCCIH), Brain, Behavior, and Immunity searches for the underlying cause and potential efficacy of both drug and non-drug interventions...

OBJECTIVES: To determine whether end-tidal CO2-guided chest compression delivery improves survival over standard cardiopulmonary resuscitation after prolonged asphyxial arrest. DESIGN: Preclinical randomized controlled study. SETTING: University animal research laboratory. SUBJECTS: 1-2-week-old swine. INTERVENTIONS: After undergoing a 20-minute asphyxial arrest, animals received either standard or end-tidal CO2-guided cardiopulmonary resuscitation...

PURPOSE OF REVIEW: MRI is becoming an indispensable diagnostic tool. The need for prolonged motion-free periods has substantially increased the need for deep sedation or anesthesia in a challenging environment. This review summarises recent literature with respect to pharmacological sedative strategies, nonpharmacological alternative approaches, airway management and safety issues in the ambulatory setting. RECENT FINDINGS: Most literature researches the pediatric patient population...

We investigated the effect of variations in ice shell thickness and of the tiger stripe fractures crossing Enceladus' south polar terrain on the moon's tidal deformation by performing finite element calculations in three-dimensional geometry. The combination of thinning in the polar region and the presence of faults has a synergistic effect that leads to an increase of both the displacement and stress in the south polar terrain by an order of magnitude compared to that of the traditional model with a uniform shell thickness and without faults...

Tidal wetlands contain large reservoirs of carbon in their soils and can sequester carbon dioxide (CO2 ) at a greater rate per unit area than nearly any other ecosystem. The spatial distribution of this carbon influences climate and wetland policy. To assist with international accords such as the Paris Climate Agreement, national-level assessments such as the United States (U.S.) National Greenhouse Gas Inventory, and regional, state, local, and project-level evaluation of CO2 sequestration credits, we developed a geodatabase (CoBluCarb) and high-resolution maps of soil organic carbon (SOC) distribution by linking National Wetlands Inventory data with the U...

BACKGROUND: The latest methacholine challenge testing (MCT) guidelines published by the European Respiratory Society recommend the characterization of nebulizers before their use in clinics and research. Such investigations are necessary for accurately determining the provocative dose of methacholine causing a 20% fall in FEV1 (PD20) delivered by a given device. The standard English Wright (Wright) jet nebulizer recommended in the 1999 guidelines by the American Thoracic Society has become difficult to obtain and possesses some characteristics that complicate the calculation of dose delivery from this device (e...

Reproduction in iteroparous marine organisms is often timed with abiotic cycles and may follow lunar, tidal amplitude, or daily cycles. Among intertidal marine invertebrates, decapods are well known to time larval release to coincide with large amplitude nighttime tides, which minimizes the risk of predation. Such bimonthly cycles have been reported for few other intertidal invertebrates. We documented the reproduction of 6 gastropod species from Panama to determine whether they demonstrate reproductive cycles, whether these cycles follow a 2-week cycle, and whether cycles are timed so that larval release occurs during large amplitude tides...

BACKGROUND: Although hypothyroidism has an insidious onset and relatively asymptomatic, exertional dyspnea and fatigue can be the presenting complaints. OBJECTIVES: The aim is to assess functional lung impairment in hypothyroid patients both at rest and during exercise. METHODS: A case-control study was carried out on 42 patients with newly diagnosed hypothyroidism and 12 control subjects. Hypothyroidism was diagnosed based on high value of thyroid stimulating hormone (TSH) ≥6 μIU/ml, and low value of free thyroxin (FT4) ≤0...

BACKGROUND: Research has shown that increased breathing frequency during cardiopulmonary resuscitation is inversely correlated with systolic blood pressure. Rescuers often hyperventilate during cardiopulmonary resuscitation (CPR). Current American Heart Association advanced cardiac life support recommends a ventilation rate of 8 -10 breaths/min. We hypothesized that a small, turbine-driven ventilator would allow rescuers to adhere more closely to advanced cardiac life support (ACLS) guidelines...

OBJECTIVE: To evaluate three routinely used tidal volumes (VT; 10, 12 and 15 mL kg(-1)) for controlled mechanical ventilation (CMV) in lung-healthy anaesthetized dogs by assessing alveolar ventilation (VTalv) and dead space (DS). STUDY DESIGN: Prospective, randomized clinical trial. ANIMALS: A total of 36 client-owned dogs. METHODS: Dogs were randomly allocated to a VT of 10 (G10), 12 (G12) or 15 (G15) mL kg(-1).

Introduction Ventilation with a bag valve mask (BVM) is a challenging but critical skill for airway management in the prehospital setting. Hypothesis Tidal volumes received during single rescuer ventilation with a modified BVM with supplemental external handle will be higher than those delivered using a standard BVM among health care volunteers in a manikin model. METHODS: This study was a randomized crossover trial of adult health care providers performing ventilation on a manikin. Investigators randomized participants to perform single rescuer ventilation, first using either a BVM modified by addition of a supplemental external handle or a standard unmodified BVM (Spur II BVM device; Ambu; Ballerup, Denmark)...

The goal of this study was to confirm the vasopressor and cardiac effects of POTENAY(®) INJETÁVEL (POT), a mephentermine-based product, given to cattle with induced vascular/cardiac depression. Ten healthy Holstein cattle (206 ± 13 kg) followed a randomized-complete-block design (RCBD) utilizing crossover study design. Each animal randomly received (1 ml/25 kg, IM) of either POT (n = 10) or volume-matched placebo control (0.9%NaCl, CP, n = 10). A subset of animals (n = 5) received POT first (day 0) while the remaining (n = 5) received CP; after a six-day washout period, cattle received the opposite compound...
