V Re, E Sacchi
Salinization and nitrate pollution are generally ascertained as the main issues affecting coastal aquifers worldwide. In arid zones, where agricultural activities also result in soil salinization, both phenomena tend to co-exist and synergically contribute to alter groundwater quality, with severe negative impacts on human populations and natural ecosystems' wellbeing. It becomes therefore necessary to understand if and to what extent integrated hydrogeochemical tools can help in distinguishing among possible different salinization and nitrate contamination origins, in order to provide adequate science-based support to local development and environmental protection...

This article attempts to explore the nexus between oil consumption, economic growth and carbon dioxide (CO2) emissions in three East Asian oil importing countries (i.e. China, South Korea and Japan) over the period 1980-2013, by using the Granger causality, Johansen cointegration test, Generalised Impulse Response functions (GIRF) and variance decompositions. The empirical findings provide evidence for the existence of a long-run relationship between oil consumption and economic growth in China and Japan. The results also point to a uni-directional causality from running from oil consumption to economic growth in China and Japan, and from oil consumption to CO2 emissions in South Korea...

ETHNOPHARMACOLOGICAL RELEVANCE: Organoleptic properties, and more specifically chemosensory cues, have been shown to guide therapeutic applications of medicinal plants. Humoral qualities, on the other hand, are widely believed to be an abstract concept, mainly applied post hoc to validate therapy. However, the nexus between humoral qualities, chemosensory properties, and medicinal plant uses has never been systematically assessed. AIM OF THE STUDY: To systematically analyse the correlations between chemosensory properties, humoral qualities, and medicinal uses of selected botanical drugs...

Public domain and commercial in silico tools were compared for their performance in predicting the skin sensitization potential of chemicals. The packages were either statistical based (Vega, CASE Ultra) or rule based (OECD Toolbox, Toxtree, Derek Nexus). In practice, several of these in silico tools are used in gap filling and read-across, but here their use was limited to make predictions based on presence/absence of structural features associated to sensitization. The top 400 ranking substances of the ATSDR 2011 Priority List of Hazardous Substances were selected as a starting point...

Global differences in the observed causes of chronic kidney disease (CKD) in children are well documented and are attributed to dissimilarities in clime, race, hereditary, and ancestry. Thus, familial clustering and disparities in CKD prevalence rates across ethnic and racial groups indicate that the progression of renal disease has a strong genetic component. Mammalian studies have demonstrated a feasible nexus between nutrition and non-genetic exposure (around the time of conception and in epigenetic changes) in the expression of major genes identified in renal organogenesis...

The failure of pancreatic islet β-cells is a major contributor to the etiology of Type 2 diabetes. β-cell dysfunction and declining β-cell mass are two mechanisms that contribute to this failure, although it is unclear if they are molecularly linked. Here, we show that the cell cycle regulator, cyclin-dependent kinase 2 (Cdk2), couples primary β-cell dysfunction to the progressive deterioration of β-cell mass in diabetes. Mice with pancreas-specific deletion of Cdk2 are glucose intolerant primarily due to defects in glucose-stimulated insulin secretion...

While p53 activity is required for tumor suppression, unconstrained p53 activity on the other hand is detrimental to the organism, resulting in inappropriate cellular death or proliferation defects. Unimpeded p53 activity is lethal in the developing embryo, underlining the need for maintaining a tight control on p53 activity during this period. The critical role of the negative regulators of p53, Mdm2 and Mdm4, in vertebrate development came to light by fatal disruption of embryogenesis that was observed with Mdm2 and Mdm4 gene deletions in mice...

Chitin, a polysaccharide with particular abundance in fungi, nematodes and arthropods is immunogenic. It acts as a threat to other organisms, to tackle which they have been endowed with chitinase enzyme. Even if this enzyme is not present in all organisms, they possess proteins having chitin-binding domain(s) (ChtBD). Many lethal viruses like Ebola, and HCV (Hepatitis C virus) have these domains to manipulate their carriers and target organisms. In keeping with the basic rule of survival, the self-origin (own body component) chitins and chitinases are protective, but that of non-self origin (from other organisms) are detrimental to health...

In virtually all cells, store-operated Ca(2+) entry signals are vital in controlling a spectrum of functions. The signals are mediated by STIM proteins in the ER and Orai channels in the PM which undergo a dynamic coupling process within discrete ER-PM junctional regions. This coupling is initiated by depletion of ER stored Ca(2+) triggering STIM proteins to undergo an intricate activation process. Thereafter, STIM proteins become trapped in the ER-PM junctions where they tether and gate PM Orai Ca(2+) channels...

Delivery room infections are frequent, and many of them could be avoided through higher standards of care. The authors examine this issue by comparing it to English and French reality. Unlike England, in Italy and France the relationship established between health facility, physician and patient is outlined in a contract. In England, the judges' decisions converge towards a better and higher protection of the patient - the actor - and facilitate the probative task. In case of infections, including those occurring in the delivery room, three issues are evaluated: the hospital's negligent conduct, damages if any and causal nexus...

The diverse mechanisms by which the plasmin(ogen) system is involved in human physiology and pathology are constantly being delineated. For many years, the plasmin(ogen) system was chiefly known as the system responsible for vascular fibrinolysis. Although this is an important function of the plasmin(ogen) system, we now recognize that plasmin(ogen) is critically important as a mediator of inflammation and the innate immune system, which impacts upon a diverse set of mechanisms underlying the pathologies of many diseases...

The epidermal growth factor receptor (EGFR) family comprises the ErbB1 (EGFR) and ErbB4 receptors as well as the 'co-receptors' ErbB2 (which does not bind EGF ligands) and ErbB3 (which lack tyrosine kinase activity). This family of receptors is essential for cardiac development, myocardial, renal and vascular function, and cardiac responses to physiological and pathological perturbations. The EGFR appears critical in protecting cardiac cells from injury, while considerable attention has focussed on neuregulin/ErbB4 signalling in potentially ameliorating cardiomyopathy/heart failure...

Glucose plasma measurements for diabetes patients are generally presented as a glucose concentration-time profile with 15-60min time scale intervals. This limited resolution obscures detailed dynamic events of glucose appearance and metabolism. Measurement intervals of 15minutes or more could contribute to imperfections in present diabetes treatment. High resolution data from mixed meal tolerance tests (MMTT) for 24 type 1 and type 2 diabetes patients were used in our present modelling. We introduce a model based on the physiological properties of transport, storage and utilization...

Environmental engineers have played a critical role in improving human and ecosystem health over the past several decades. These contributions have focused on providing clean water and air as well as managing waste streams and remediating polluted sites. As environmental problems have become more global in scale and more deeply entrenched in sociotechnical systems, the discipline of environmental engineering must grow to be ready to respond to the challenges of the coming decades. Here we make the case that environmental engineers should play a leadership role in the development of climate change mitigation technologies at the carbon-water nexus (CWN)...

It took about 30 y after Wilhelm Konrad Roentgen's discovery of x rays and Henri Becquerel's discovery of natural radioactivity for scientists in the civilized world to formulate recommendations on exposure to ionizing radiation. We know of these efforts today because the organizations that resulted from the concerns raised in 1928 at the Second International Congress of Radiology still play a role in radiation protection. The organizations are known today as the International Commission on Radiological Protection and, in the United States, the National Council on Radiation Protection and Measurements (NCRP)...

BACKGROUND: The impact of formulary management strategies on utilization and expenditures in overactive bladder (OAB) treatment has not been extensively investigated. In 2013, step therapy (ST) policies for 2 branded OAB treatments, mirabegron and fesoterodine, were removed from Humana Medicare Advantage Prescription Drug (MAPD) plans and Medicare prescription drug plans (PDP), allowing for an examination of the effect of ST policies on OAB medication use patterns and costs. OBJECTIVE: To assess the impact of removal of formulary restriction policies for mirabegron and fesoterodine on medication utilization patterns and costs associated with OAB treatment in Medicare patients...

There is convincing evidence that many young people who are in the justice system have had contact with child protection services and that victims of childhood maltreatment are at increased risk of subsequent youth justice involvement. In Australia, however, there have been few longitudinal studies that have examined these associations and relatively less is known in this area. This study examines the overlap between the child protection and youth justice involvement in South Australia, and determines how substantiated maltreatment and variations in these experiences (e...

How do we make a difference? This paper traces the connections made between quantified knowledge, population health, and social justice by examining the efforts of population scientists to assess sexuality as a point of difference within population-based data systems, including on national health and social surveys, electronic medical records, and the Census. Population scientists emphasize the importance of measuring social difference in order to identify and remedy structural disadvantage. This evaluation requires the assessment of difference and the comparison of distinct groups across standardized outcome measures...
