Discrimination by Gender and Disability Status: Do Worker Perceptions Match Statistical Measures?

We explore whether perceptions of discrimination are related to ordinary statistical measures. The majority of disabled respondents report feeling some discrimination due to their disability, the majority of women feel some discrimination because of their gender, and a surprising number of men also report some discrimination. We do not find a strong link between perceptions of discrimination and measured discrimination perhaps because those who perceive discrimination feel that it occurs along other dimensions than pay. However, we do find a connection between whether a person feels his or her income is inadequate and measured discrimination for all groups studied

Post Closure Inspection and Monitoring Report for Corrective Action Unit 110: Area 3 Waste Management Division U-3ax/bl Crater, Nevada Test Site, Nevada

This inspection and monitoring report has been prepared for the Area 3 Waste Management Division (WMD) U-3ax/bl Crater Corrective Action Unit (CAU) 110 in accordance with the Federal Facility Agreement and Consent Order (FFACO) of 1996. This inspection and monitoring report provides an analysis and summary for site inspections, meteorological information, and soil moisture monitoring data obtained at CAU 110, located in Area 3 of the Nevada Test Site (NTS), Nye County, Nevada. This report is the first post-closure report on the Area 3 WMD U-3ax/bl Crater, and covers the period January 2001 to June 2002. Inspections of the Area 3 WMD U-3ax/bl Crater cover area are conducted to determine and document the physical condition of the cover, facilities, and any unusual conditions that could impact the proper operation of the waste unit cover. The objective of the soil moisture monitoring program is to monitor the stability of soil moisture conditions within the upper 2.4 meters (m) (8 feet [ft]) of the cover and detect changes that may be indicative of moisture movement exceeding the design's performance expectations

The role of Tyr(605) and Ala(607) of thimet oligopeptidase and Tyr(606) and Gly(608) of neurolysin in substrate hydrolysis and inhibitor binding

The physicochemical properties of TOP (thimet oligopeptidase) and NEL (neurolysin) and their hydrolytic activities towards the FRET (fluorescence resonance energy transfer) peptide series AbzGFSXFRQ-EDDnp [where Abz is o-aminobenzoyl; X = Ala, Ile, Leu, Phe, Tyr, Trp, Ser, Gln, Glu, His, Arg or Pro; and EDDnp is N-(2,4-dinitrophenyl)-ethylenediamine] were compared with those of site-mutated analogues. Mutations at Tyr(605) and Ala(607) in TOP and at Tyr(606) and Gly(608) in NEL did not affect the overall folding of the two peptidases, as indicated by their thermal stability, CD analysis and the pH-dependence of the intrinsic fluorescence of the protein. the kinetic parameters for the hydrolysis of substrates with systematic variations at position P-1 showed that Tyr(605) and Tyr(606) of TOP and NEL respectively, played a role in subsite S-1. Ala(607) of TOP and Gly(608) of NEL contributed to the flexibility of the loops formed by residues 600-612 (GHLAGGYDGQYYG; one-letter amino acid codes used) in NEL and 599-611 (GHLAGGYDAQYYG; one-letter amino acid codes used) in TOP contributing to the distinct substrate specificities, particularly with an isoleucine residue at P-1. TOP Y605A was inhibited less efficiently by JA-2 {N-[1-(R,S)-carboxy-3-phenylpropyl]Ala-Aib-Tyr-p-aminobenzoate}, which suggested that the aromatic ring of Ty,105 was an important anchor for its interaction with wild-type TOP. the hydroxy groups of Tyr 605 and Tyr.. did not contribute to the pH-activity profiles, since the pKs obtained in the assays of mutants TOP Y605F and NEL Y606F were similar to those of wild-type peptidases. However, the pH-k(cat)/K-m dependence curve of TOP Y605A differed from that of wild-type TOP and from TOP Y606F. These results provide insights into the residues involved in the substrate specificities of TOP and NEL and how they select cytosolic peptides for hydrolysis.Universidade Federal de São Paulo, Dept Biofis, BR-04044020 São Paulo, BrazilInst Butantan, Lab Especial Toxinol Aplicada, CAT, CEPID, BR-05467010 São Paulo, BrazilUniv São Paulo, Inst Ciencias Biomed, Dept Biol Celular & Desenvolvimento, Programa Biol Celular, BR-05508900 São Paulo, BrazilUniv São Paulo, Lab Neurociencias, BR-03071000 São Paulo, BrazilUniv Mogi das Cruzes, CIIB, BR-08780911 Mogi Das Cruzes, SP, BrazilUniversidade Federal de São Paulo, Dept Biofis, BR-04044020 São Paulo, BrazilWeb of Scienc

Modulation of subventricular zone oligodendrogenesis: a role for hemopressin?

Neural stem cells (NSCs) from the subventricular zone (SVZ) have been indicated as a source of new oligodendrocytes to use in regenerative medicine for myelin pathologies. Indeed, NSCs are multipotent cells that can self-renew and differentiate into all neural cell types of the central nervous system. In normal conditions, SVZ cells are poorly oligodendrogenic, nevertheless their oligodendrogenic potential is boosted following demyelination. Importantly, progressive restriction into the oligodendrocyte fate is specified by extrinsic and intrinsic factors, endocannabinoids being one of these factors. Although a role for endocannabinoids in oligodendrogenesis has already been foreseen, selective agonists and antagonists of cannabinoids receptors produce severe adverse side effects. Herein, we show that hemopressin (Hp),a modulator of CB1 receptors, increased oligodendroglial differentiation in SVZ neural stem/progenitor cell cultures derived from neonatal mice. The original results presented in this work suggest that Hp and derivates may be of potential interest for the development of future strategies to treat demyelinating diseases

Widespread forest vertebrate extinctions induced by a mega hydroelectric dam in lowland Amazonia

Mega hydropower projects in tropical forests pose a major emergent threat to terrestrial and freshwater biodiversity worldwide. Despite the unprecedented number of existing, underconstruction and planned hydroelectric dams in lowland tropical forests, long-term effects on biodiversity have yet to be evaluated. We examine how medium and large-bodied assemblages of terrestrial and arboreal vertebrates (including 35 mammal, bird and tortoise species) responded to the drastic 26-year post-isolation history of archipelagic alteration in landscape structure and habitat quality in a major hydroelectric reservoir of Central Amazonia. The Balbina Hydroelectric Dam inundated 3,129 km2 of primary forests, simultaneously isolating 3,546 land-bridge islands. We conducted intensive biodiversity surveys at 37 of those islands and three adjacent continuous forests using a combination of four survey techniques, and detected strong forest habitat area effects in explaining patterns of vertebrate extinction. Beyond clear area effects, edge-mediated surface fire disturbance was the most important additional driver of species loss, particularly in islands smaller than 10 ha. Based on species-area models, we predict that only 0.7% of all islands now harbor a species-rich vertebrate assemblage consisting of ≥80% of all species. We highlight the colossal erosion in vertebrate diversity driven by a man-made dam and show that the biodiversity impacts of mega dams in lowland tropical forest regions have been severely overlooked. The geopolitical strategy to deploy many more large hydropower infrastructure projects in regions like lowland Amazonia should be urgently reassessed, and we strongly advise that long-term biodiversity impacts should be explicitly included in pre-approval environmental impact assessments

A Cross-Cultural Evaluation of Liking and Perception of Salted Butter Produced from Different Feed Systems

peer-reviewedPerception and liking among Irish, German and USA consumers of salted butter produced from different feed systems—outdoor grass (FS-GRSS), grass/clover (FS-CLVR), and indoor concentrate (FS-TMR)—was investigated. A consumer study was conducted in all three countries. Irish and German assessors participated in ranking descriptive analysis (RDA), whereas descriptive analysis (DA) was carried out by a trained panel in the USA. Volatile analysis was conducted to identify differences in aroma compounds related to cow diet. Overall, there was no significant difference in overall liking of the butters, among USA, German and Irish consumers, although cross-cultural preferences were evident. Sensory attribute differences based on cow diet were evident across the three countries, as identified by German and Irish assessors and trained USA panelists, which are likely influenced by familiarity. The abundance of specific volatile aromatic compounds, especially some aldehydes and ketones, were significantly impacted by the feed system and may also contribute to some of the perceived sensory attribute differences in these butters

Evidence for distinct coastal and offshore communities of bottlenose dolphins in the north east Atlantic.

Bottlenose dolphin stock structure in the northeast Atlantic remains poorly understood. However, fine scale photo-id data have shown that populations can comprise multiple overlapping social communities. These social communities form structural elements of bottlenose dolphin (Tursiops truncatus) [corrected] populations, reflecting specific ecological and behavioural adaptations to local habitats. We investigated the social structure of bottlenose dolphins in the waters of northwest Ireland and present evidence for distinct inshore and offshore social communities. Individuals of the inshore community had a coastal distribution restricted to waters within 3 km from shore. These animals exhibited a cohesive, fission-fusion social organisation, with repeated resightings within the research area, within a larger coastal home range. The offshore community comprised one or more distinct groups, found significantly further offshore (>4 km) than the inshore animals. In addition, dorsal fin scarring patterns differed significantly between inshore and offshore communities with individuals of the offshore community having more distinctly marked dorsal fins. Specifically, almost half of the individuals in the offshore community (48%) had characteristic stereotyped damage to the tip of the dorsal fin, rarely recorded in the inshore community (7%). We propose that this characteristic is likely due to interactions with pelagic fisheries. Social segregation and scarring differences found here indicate that the distinct communities are likely to be spatially and behaviourally segregated. Together with recent genetic evidence of distinct offshore and coastal population structures, this provides evidence for bottlenose dolphin inshore/offshore community differentiation in the northeast Atlantic. We recommend that social communities should be considered as fundamental units for the management and conservation of bottlenose dolphins and their habitat specialisations

The four pillars of HFrEF therapy : is it time to treat heart failure regardless of ejection fraction?

The syndrome of heart failure (HF) has historically been dichotomized based on clinical trial inclusion criteria into patients with a reduced or preserved left ventricular ejection fraction (LVEF) using a cut-off of above or below 40%. The majority of trial evidence for the benefits of disease-modifying pharmacological therapy has been in patients with HF with reduced ejection fraction (HFrEF), i.e. those with an LVEF ≤40%. Recently, the sodium-glucose co-transporter 2 inhibitors empagliflozin and dapagliflozin have been shown to be the first drugs to improve outcomes in HF across the full spectrum of LVEF. There is, however, growing evidence that the benefits of many of the neurohumoral modulators shown to be beneficial in patients with HFrEF may extend to those with a higher LVEF above 40% but still below the normal range, i.e. HF with mildly reduced ejection fraction (HFmrEF). Whether the benefits of some of these medications also extend to patients with HF and preserved ejection fraction (HFpEF) is an area of ongoing debate. This article will review the evidence for HF treatments across the full spectrum of LVEF, provide an overview of recently updated clinical practice guidelines, and address the question whether it may now be time to treat HF with some therapies regardless of ejection fraction

Advanced solid state nano-electrochemical sensors and system for agri 4.0 applications

Global food production needs to increase in order to meet the demands of an ever growing global population. As resources are finite, the most feasible way to meet this demand is to minimize losses and improve efficiency. Regular monitoring of factors like animal health, soil and water quality for example, can ensure that the resources are being used to their maximum efficiency. Existing monitoring techniques however have limitations, such as portability, turnaround time and requirement for additional reagents. In this work, we explore the use of micro- and nano-scale electrode devices, for the development of an electrochemical sensing platform to digitalize a wide range of applications within the agri-food sector. With this platform, we demonstrate the direct electrochemical detection of pesticides, specifically clothianidin and imidacloprid, with detection limits of 0.22 ng/mL and 2.14 ng/mL respectively, and nitrates with a detection limit of 0.2 µM. In addition, interdigitated electrode structures also enable an in-situ pH control technique to mitigate pH as an interference and modify analyte response. This technique is applied to the analysis of monochloramine, a common water disinfectant. Concerning biosensing, the sensors are modified with bio-molecular probes for the detection of both bovine viral diarrhea virus species and antibodies, over a range of 1 ng/mL to 10 µg/mL. Finally, a portable analogue front end electronic reader is developed to allow portable sensing, with control and readout undertaken using a smart phone application. Finally, the sensor chip platform is integrated with these electronics to provide a fully functional end-to-end smart sensor system compatible with emerging Agri-Food digital decision support tools
