In ecosystems with high fish species endemicity, such as Mediterranean-type rivers, biogeographical differences among ecoregions present serious obstacles to developing broadly-applicable river bioassessment indices. This impediment has contributed to a serious time-lag in developing EU policy-relevant fish-based indices in the Eastern Mediterranean countries. Here we present the first model-based fish index for the Eastern Mediterranean (the Hellenic Fish Index, HeFI) in an effort to overcome biogeographic differences among the area's biotically heterogeneous rivers...

Cardiovascular toxicity of lead (Pb) manifests primarily as an effect on blood pressure and eventual increased risk of atherosclerosis and cardiovascular events. Therefore, we investigated vascular inflammatory biomarkers and cardiovascular effects of Pb-exposed children. A total of 590 children (3-7 years old) were recruited from Guiyu (n = 337), an electronic waste (e-waste)-exposed group, and Haojiang (n = 253), a reference group, from November to December 2016. We measured child blood Pb levels (BPbs), and systolic and diastolic blood pressure...

BACKGROUND: Hospital-acquired pressure injuries are a costly and largely preventable complication occurring in a variety of acute care settings. Patients admitted to the intensive care unit are at greater risk of developing pressure injuries. OBJECTIVE: To determine whether the efficiency of scales to measure pressure injury risk increase when a continuously updated 3-day moving average method is used. METHODS: With a retrospective cohort design we recruited 3085 patients treated between June 2011 and February 2015 in the intensive care unit of a tertiary level university hospital...

BACKGROUND: Female survivors of sexual violence in conflict experience not only physical and psychological sequelae from the event itself, but often many negative social outcomes, such as rejection and ostracisation from their families and community. Male relatives - whether husbands, fathers, brothers - play a key role in determining how the family and community respond to a survivor of sexual violence. Understanding these perspectives could help improve services for survivors of sexual violence, as well as their families and communities...

Jun-Sik Sin
In this paper, we study electrostatic properties between two similar or oppositely charged surfaces immersed in an electrolyte solution by using the mean-field approach accounting for solvent polarization and non-uniform size effects. Applying a free energy formalism accounting for unequal ion sizes and orientational ordering of water dipoles, we derive coupled and self-consistent equations to calculate electrostatic properties between charged surfaces. Electrostatic properties for similarly charged surfaces depend on the counterion size but not on the coion size...

One of the most significant challenges in contemporary lipidomics lies in the separation and identification of lipid isomers that differ only in double bond unsaturation site(s) or geometric configuration. While analytical separation techniques including ion mobility spectrometry (IMS) and liquid chromatography (LC) can separate isomeric lipids under appropriate conditions, conventional tandem mass spectrometry cannot provide unequivocal identification. To address this challenge, we have implemented ozone-induced dissociation (OzID) in-line with LC, IMS and high resolution mass spectrometry...

Shi Liu, R E Cohen
Piezoelectrics with negative longitudinal piezoelectric coefficients will contract in the direction of an applied electric field. Such piezoelectrics are thought to be rare, but there is no fundamental physics preventing the realization of negative longitudinal piezoelectric effect in a single-phase material. Using first-principles calculations, we demonstrate that several hexagonal ABC ferroelectrics possess significant negative longitudinal piezoelectric effects. The data mining of a first-principles-based database of piezoelectrics reveals that this effect is a general phenomenon...

Understanding adaptation to complex environments requires information about how exposure to one selection pressure affects adaptation to others. For bacteria, antibiotics and viral parasites (phages) are two of the most common selection pressures and are both relevant for treatment of bacterial infections: increasing antibiotic resistance is generating significant interest in using phages in addition or as an alternative to antibiotics. However, we lack knowledge of how exposure to antibiotics affects bacterial responses to phages...

BACKGROUND: Esophageal perforations and postoperative leakage of esophagogastrostomies are considered to be life-threatening conditions due to the potential development of mediastinitis and consecutive sepsis. Vacuum-assisted closure (VAC) techniques, a well-established treatment method for superficial infected wounds, are based on a negative pressure applied to the wound via a vacuum-sealed sponge. Endoluminal VAC (E-VAC) therapy as a treatment for GI leakages in the rectum was introduced in 2008...

Lack of hunting and predators and proximity to human communities make suburban forests prone to high deer abundance and non-native plant invasions. I investigated these likely drivers of community structure in the herb layers of six suburban forests in one region of New Jersey, USA. In 223 plots I assessed the herb layer response to 2.5 years with or without deer fencing and the early stage of invasion from seed additions of Microstegium vimineum, an invasive, annual grass. Non-native plants and herbaceous native plants were affected very little by fencing or M...

A ten-year-old boy presented to the hospital with body ache and joint pains for two months and headache, vomiting, and skin rash for three days. He was drowsy and lethargic at admission. Physical examination revealed bilateral papilledema. There were no cranial nerve involvement, neuromotor deficit, or signs of meningeal irritation. Computed tomography and magnetic resonance imaging of the brain did not reveal any evidence of cerebral edema or space occupying lesion. In view of the high endemicity of brucellosis in the area, Brucella agglutination test (BAT) was done at the time of admission and was negative...

OBJECTIVE: Asthma is known as a chronic inflammatory lung disease which has also systemic features. Insulin-like growth factor I (IGF-I) plays a role for asthma pathogenesis. Controversially, IGF-binding protein 3 (IGFBP3) blocks asthma development. That is why IGF-I and IGFBP3 are targeted for future therapeutic treatments of asthma. We aimed to investigate serum level of IGF-I and IGFBP3 in patients with asthma. This study was performed in 27 asthma and 23 healthy individuals. Serum levels of IGF-I and IGFBP3 were measured by human ELISA assay kits...

Hypertension is the major risk factor for cardiovascular diseases and is one of the primary causes of morbidity and mortality worldwide. Apelin levels and NO bioavailability are impaired in older hypertensive patients. Exercise is an effective intervention for treating hypertension. Our purpose was to evaluate the effect of high-intensity interval training on blood pressure, apelin, and NOx plasma levels in older treated hypertensive individuals. Thirty treated hypertensive subjects (61.70 ± 5.78 years, 17 males, 13 females) were randomly divided into 6 weeks of high-intensity interval training (n = 15) and control (n = 15)...
