Anti-microbial cetylpyridinium chloride suppresses mast cell function by targeting tyrosine phosphorylation of Syk kinase.

Cetylpyridinium chloride (CPC) is a quaternary ammonium antimicrobial used in numerous personal care products, human food, cosmetic products, and cleaning solutions. Yet, there is minimal published data on CPC effects on eukaryotes, immune signaling, and human health. Previously, it was shown that low-micromolar CPC inhibits rat mast cell function by inhibiting antigen (Ag)-stimulated Ca mobilization, microtubule polymerization, and degranulation.

Recovery opioid overdose team (ROOT) pilot program evaluation: A community-wide post-overdose response strategy.

Effective interventions for overdose survivors are needed in the emergency departments (EDs). One promising model is the use of peer recovery coaches to engage with survivors in EDs, followed by partnering with community case management navigators to connect survivors to recovery support and treatment services. This paper describes the evaluation of a pilot program, the Recovery Opioid Overdose Team (ROOT), a warm hand-off system that links survivors to treatment services post-ED discharge.

How Might We Assess and Manage the Effects of Underwater Noise on Populations of Marine Animals?

The European Union Marine Strategy Framework Directive (MSFD) aims to achieve good environmental status (GES) in European seas by 2020. One of the features of GES is that underwater sound should not adversely affect the marine environment. Direct injury of marine life may occur, but a more pervasive effect is likely to be through the cumulative indirect effects on behavior.

The European Marine Strategy: Noise Monitoring in European Marine Waters from 2014.

The European Marine Strategy Framework Directive requires European member states to develop strategies for their marine waters leading to programs of measures that achieve or maintain good environmental status (GES) in all European seas by 2020. An essential step toward reaching GES is the establishment of monitoring programs, enabling the state of marine waters to be assessed on a regular basis. A register for impulsive noise-generating activities would enable assessment of their cumulative impacts on wide temporal and spatial scales; monitoring of ambient noise would provide essential insight into current levels and any trend in European waters.

What caused the UK's largest common dolphin (Delphinus delphis) mass stranding event?

On 9 June 2008, the UK's largest mass stranding event (MSE) of short-beaked common dolphins (Delphinus delphis) occurred in Falmouth Bay, Cornwall. At least 26 dolphins died, and a similar number was refloated/herded back to sea. On necropsy, all dolphins were in good nutritive status with empty stomachs and no evidence of known infectious disease or acute physical injury.

The magnitude of global marine species diversity.

Background: The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species of the world and used this baseline to estimate how many more species, partitioned among all major eukaryotic groups, may be discovered.

Results: There are ∼226,000 eukaryotic marine species described.

Intragastric infusion of pea-protein hydrolysate reduces test-meal size in rats more than pea protein.

Because protein hydrolysates are digested faster than the corresponding proteins, they may increase or hasten the acute eating-inhibitory effect of protein. Potential mediating mechanisms include accelerated or greater release of satiating gut peptides and activation of metabolic signals that inhibit eating. We tested these hypotheses in adult male rats that were surgically equipped with intragastric (IG) cannulas and adapted to 30-min test meals at dark onset after 14-h food deprivation.

Changes in cerebral arterial, tissue and venous oxygenation with evoked neural stimulation: implications for hemoglobin-based functional neuroimaging.

Little is known regarding the changes in blood oxygen tension (P(O2)) with changes in brain function. This work aimed to measure the blood P(O2) in surface arteries and veins as well as tissue with evoked somato-sensory stimulation in the anesthetized rat. Electrical stimulation of the forepaw induced average increases in blood flow of 44% as well as increases in the tissue P(O2) of 28%.

Protein hydrolysates induce CCK release from enteroendocrine cells and act as partial agonists of the CCK1 receptor.

Protein has been reported to be the most satiating of all macronutrients. Upon gastrointestinal digestion, peptides are generated that stimulate the release of satiety hormones such as cholecystokinin (CCK) from enteroendocrine cells. As such, bioactive peptides could be the target of Functional Food ingredients with satiating effects.

Ecosystem objectives to support the UK vision for the marine environment.

European Maritime States already have commitments to protect species and habitats and maintain quality standards in coastal and offshore waters. These are a direct response to environmental legislation in Europe and commitments made to biodiversity conservation in OSPAR and at the World Summit on Sustainable Development. An integrated approach to management requires that these are consistent with the requirements for sustainable development, and include wider social considerations and active stakeholder participation.

Source of nonlinearity in echo-time-dependent BOLD fMRI.

Stimulation-induced changes in transverse relaxation rates can provide important insight into underlying physiological changes in blood oxygenation level-dependent (BOLD) contrast. It is often assumed that BOLD fractional signal change (DeltaS/S) is linearly dependent on echo time (TE). This relationship was evaluated at 9.

Is it possible to predict or prevent third degree tears?

Objectives: This paper reviews the causes anal sphincter injury during vaginal delivery. It emphasises that they are not usually the result of poor obstetric care. The role of the colorectal surgeon in their management is discussed.

Anal function following third degree tears.

Objective: To assess the anal function of women who have suffered a third degree perineal tear during parturition.

Patients: Fifty-three consecutive women who sustained a third degree tear, between January 1998 and March 2000, at the Princess Anne Maternity Unit, Royal Bolton Hospital were assessed.

Methods: Women were assessed at 3 months post partum using the Cleveland Clinic Incontinence Score, digital assessment of anal sphincter and endo-anal ultrasound scan.

Medical treatment of miscarriage in a district general hospital is safe and effective up to 12 weeks' gestation.

The findings are reported of a retrospective study of 207 women undergoing medical evacuation of the uterus for first trimester miscarriage, using mifepristone followed by a single dose of oral misoprostol. All women had the diagnosis confirmed by ultrasonography. Complete medical evacuation was achieved in 88% of cases.

Mifepristone and misoprostol for medical termination of pregnancy: the effectiveness of a flexible regimen.

Background: Mifepristone, followed 48 hours later by administration of misoprostol, is a well-established regimen for medical termination of pregnancy (TOP). Although this regimen is effective, its inflexibility may limit its provision in an outpatient service.

Objective: To confirm that misoprostol administration is effective whether administered 24, 48 or 72 hours after oral mifepristone.

Cytochrome oxidase subunit VI of Trypanosoma brucei is imported without a cleaved presequence and is developmentally regulated at both RNA and protein levels.

Mitochondrial respiration in the African trypanosome undergoes dramatic developmental stage regulation. This requires co-ordinated control of components encoded by both the nuclear genome and the kinetoplast, the unusual mitochondrial genome of these parasites. As a model for understanding the co-ordination of these genomes, we have examined the regulation and mitochondrial import of a nuclear-encoded component of the cytochrome oxidase complex, cytochrome oxidase subunit VI (COXVI).
