Effects of marine noise pollution on Mediterranean fishes and invertebrates: A review.

Marine noise pollution (MNP) can cause a multitude of impacts on many organisms, but information is often scattered and general outcomes difficult to assess. We have reviewed the literature on MNP impacts on Mediterranean fish and invertebrates. Both chronic and acute MNP produced by various human activities - e.

Influence of prior appendectomy and cholecystectomy on Clostridioides difficile infection recurrence and mortality.

Background: Remote appendectomy was linked to increased incidence of Clostridioides difficile infection (CDI). We evaluated the effect of absence of vermiform appendix and/or gallbladder on recurrence rate and severity of CDI.

Methods: We assessed a systemwide patient cohort diagnosed with initial CDI in 2014 (n = 250).

Assessment of the use of Oblada melanura (L. 1758) otolith fluctuating asymmetry as environmental disturbance indicator.

Human impact on the environment is of widespread concern. The majority of anthropogenic impacts are centred on coastal ecosystems, so surveying them is an important step in the protection of the marine environment. We have tested Oblada melanura (L.

American hybrid: Donald Trump and the strange merger of populism and plutocracy.

Any effort to situate Trump's ascendance in the broader currents of cross-national developments, or in the longer course of American political development, must begin by recognizing it as a curious hybrid of populism and plutocracy. Although American right-wing populism has real social roots, it has long been nurtured by powerful elites seeking to undercut support for modern structures of economic regulation and the welfare state. American political institutions offered a distinctive opportunity for a populist figure to draw on this fury to first capture the nomination of the GOP, and from that position to ascend to the White House.

Task2 potassium channels set central respiratory CO2 and O2 sensitivity.

Task2 K(+) channel expression in the central nervous system is surprisingly restricted to a few brainstem nuclei, including the retrotrapezoid (RTN) region. All Task2-positive RTN neurons were lost in mice bearing a Phox2b mutation that causes the human congenital central hypoventilation syndrome. In plethysmography, Task2(-/-) mice showed disturbed chemosensory function with hypersensitivity to low CO(2) concentrations, leading to hyperventilation.

5-hydroxyindole-2-carboxylic acid amides: novel histamine-3 receptor inverse agonists for the treatment of obesity.

Obesity is a major risk factor in the development of conditions such as hypertension, hyperglycemia, dyslipidemia, coronary artery disease, and cancer. Several pieces of evidence across different species, including primates, underscore the implication of the histamine 3 receptor (H(3)R) in the regulation of food intake and body weight and the potential therapeutic effect of H(3)R inverse agonists. A pharmacophore model, based on public information and validated by previous investigations, was used to design several potential scaffolds.

Immunogenicity and safety assessments after one and two doses of a refrigerator-stable tetravalent measles-mumps-rubella-varicella vaccine in healthy children during the second year of life.

Background: Measles, mumps, and rubella (MMR) and varicella (V) vaccines are often coadministered at 1 clinic visit. This study (104389/NCT00127023) was undertaken to assess the immunogenicity and safety of a new refrigerator-stable tetravalent MMRV vaccine after 1 dose and after 2 doses administered during the second year of life.

Methods: Nine hundred seventy healthy children aged 10-21 months received 2 doses of MMRV vaccine (Priorix-Tetra; GlaxoSmithKline Biologicals, Rixensart, Belgium) 42 days apart (MMRV group; N = 732) or 1 dose of MMR vaccine (Priorix) coadministered with varicella vaccine (Varilrix) followed by a second dose of only MMR vaccine 42 days later (MMR + V group; N = 238).

Pituicyte stellation is prevented by RhoA-or Cdc42-dependent actin polymerization.

Our aim was to shed light on different steps leading from metabotropic receptor activation to changes in cell shape, such as those that characterize the morphological plasticity of neurohypophysial astrocytes (pituicytes). Using explant cultures of adult rat pituicytes, we have previously established that adenosine A1 receptor activation induces stellation via inhibition of RhoA monomeric GTPase and subsequent disruption of actin stress fibers. Here, we rule out RhoA phosphorylation as a mechanism for that inhibition.

Engaging staff in the Magnet journey: the key is communication.

A Midwestern acute care facility shares its successful internal communication plan to engage stakeholders and describes its significance in achieving designation as a Magnet hospital. This plan remains a framework for ongoing communications toward sustaining a Magnet culture, completing annual interim reports, and preparing for redesignation in 4 years.

A(2b) receptor mediates adenosine inhibition of taurine efflux from pituicytes.

Background Information: Recent work suggests that part of the control of vasopressin output is mediated by taurine released from pituicytes, the astroglial cells of the neurohypophysis. Taurine release, in turn, is stimulated by hypotonic conditions and by vasopressin itself. As adenosine is generated from ATP co-released with vasopressin, it appeared important to study its effects on taurine efflux from pituicytes.

Assessing Heterodera glycines-Resistant and Susceptible Cultivar Yield Response.

The soybean cyst nematode Heterodera glycines (SCN) is of major economic importance and widely distributed throughout soybean production regions of the United States where different maturity groups with the same sources of SCN resistance are grown. The objective of this study was to assess SCN-resistant and -susceptible soybean yield responses in infested soils across the north-central region. In 1994 and 1995, eight SCN-resistant and eight SCN-susceptible public soybean cultivars representing maturity groups (MG) I to IV were planted in 63 fields, either infested or noninfested, in 10 states in the north-central United States.

Suppression of potassium channels elicits calcium-dependent plateau potentials in suprachiasmatic neurons of the rat.

By using whole-cell recordings in acute and organotypic hypothalamic slices, we found that following K+ channel blockade, sustained plateau potentials can be elicited by current injection in suprachiasmatic neurons. In an attempt to determine the ionic basis of these potentials, ion-substitution experiments were carried out. It appeared that to generate plateau potentials, calcium influx was required.

The stress axis, stanniocalcin, and ion balance in rainbow trout.

In teleosts, the stress hormone cortisol and the calcium regulatory hormone stanniocalcin (STC) are both involved in the regulation of ion balance. Under stressful conditions, ion balance is easily disturbed as stressors via the stress signals they evoke disturb easily and primarily gill function. The gills are key in fish gas exchange and ion regulation.

Myodulin is a novel potential angiogenic factor in skeletal muscle.

We examined the expression and function of a gene we previously cloned from its downregulation in a muscle atrophy model. The encoded protein was named myodulin because of sequence homologies with the cartilage-specific chondromodulin-I (ChM-I) protein, its restricted expression in skeletal muscle tissue, and its modulating properties on vascular endothelial cells described here. We investigated the expression of myodulin in muscle fibers and cultured muscle cells.

Retrenchment and restructuring in an age of austerity: what (if anything) can be learned from the affluent democracies?

The article discusses some difficulties of drawing implications from welfare state reform in the Organisation for Economic Co-operation and Development for "middle-income countries", and whose welfare states have been less well institutionalized. It is argued that globalization's role in contemporary social policy dynamics were not unimportant, but social processes occurring within national contexts were probably more important. There is not a single "new politics of the welfare state" but distinct political dynamics in different "regimes" or "configurations", which are characterized by different problem loads and different structures of political opportunity.

Effect of vasopressin on the input-output properties of rat facial motoneurons.

Vasopressin can directly excite facial motoneurons in young rats and mice. It acts by generating a persistent inward current, which is Na(+)-dependent, tetrodotoxin-insensitive and voltage-gated. This peptide-evoked current is unaffected by Ca(++) or K(+) channel blockade and is modulated by extracellular divalent cations.

Neurohypophysial hormone receptors and second messengers in trout hepatocytes.

Neurohypophysial hormone receptors and second messengers were studied in trout (Oncorhynchus mykiss) hepatocytes. Arginine vasotocin (AVT) and isotocin (IT) elicited a concentration-dependent inhibition of cAMP accumulation in the presence of 5x10(-8) M glucagon (maximal effect for 4.5x10(-7) M and 1.

Soybean Cyst Nematode Reproduction in the North Central United States.

An experiment was conducted in Heterodera glycines-infested fields in 40 north central U.S. environments (21 sites in 1994 and 19 sites in 1995) to assess reproduction of this nematode.

Vasopressin and oxytocin action in the brain: cellular neurophysiological studies.

During the last two decades it has become apparent that vasopressin (VP) and oxytocin (OT), in addition to playing a role as peptide hormones, also act as neurotransmitters. Morphological studies and electrophysiological recordings have shown a close anatomical correlation between the presence of these receptors and the neuronal responsiveness to VP or OT. These compounds have been found to affect membrane excitability in neurons located in the hippocampus, hypothalamus, lateral septum, brainstem, spinal cord and superior cervical ganglion.

Action of a metabotropic glutamate receptor agonist in rat lateral septum: induction of a sodium-dependent inward aftercurrent.

The mechanism by which (1S,3R)-ACPD, a metabotropic glutamate receptor agonist, induces burst firing in lateral septal neurons of the rat was investigated in coronal brainstem slices. Membrane currents were characterized in voltage clamp using whole-cell recordings. In the presence of (1S,3R)-ACPD, following depolarizing voltage jumps, repolarization towards the holding potential generated an inward aftercurrent.

Effect of Soybean Cyst Nematode (Heterodera glycines) on Yield of Resistant and Susceptible Soybean Cultivars Grown in Ohio.

Soybean (Glycine max) producers in Ohio rarely use soybean cyst nematode (Heterodera glycines, SCN)-resistant cultivars because of concerns over limited yield potential and lack of resistance to Phytophthora sojae. A two-year study was initiated to determine grain yield and nematode population increase on soybean cyst nematode-resistant cultivars in maturity groups II and III in production fields. Sites differed in soil texture, nematode densities, and P.

Distribution of Heterodera glycines in Ohio.

A 4-year systematic survey for the presence of soybean cyst nematode Heterodera glycines in Ohio soybean fields was initiated in 1992. A total of 667 soybean fields in 63 counties was sampled. Heterodera glycines was present in 91 fields in 40 counties based on soil samples collected, and in one field in each of three additional counties based on soil samples submitted to the Plant and Pest Diagnostic Clinic or through a preliminary survey conducted in 1991.

A V1-type receptor for mediating the neurohypophysial hormone-induced ACTH release in trout pituitary.

We analysed the effects of specific neurohypophysial analogues for pharmacological characterization of the type of vasotocin receptor involved in the control of the adrenocorticotrophin hormone (ACTH) release from the perifused pituitary in the rainbow trout, Oncorhynchus mykiss. Mammalian corticotrophin releasing factor (CRF) and teleostean neurohypophysial peptides (arginine vasotocin (AVT) and isotocin (IT)) stimulated ACTH release. Analysis of concentrations giving half-maximal effects (D50) showed that these peptides affected ACTH release in the following order of potency: CRF (8 x 10(-13) M) > AVT (2 x 10(-10) M) > IT (10(-7) M).
