Psychometric properties of Indonesian slums dwellers' place attachment.

Social scientists have long considered place attachment to be an important factor in promoting environmentally sustainable behaviours among individuals. Raymond and colleagues have developed a five-factor place attachment measure, comprising place dependence, nature dependence, place attachment, family bonding, and friendship bonding, that encompasses most of the differentiations made and that has been amply tested for validity and reliability. However, the bulk of these confirmatory studies have been conducted in Western societies, neglecting people in the Global South and particularly people living in unstable, environmentally fragile regions such as slum areas.

Current Methods for Identifying Plasma Membrane Proteins as Cancer Biomarkers.

Plasma membrane proteins are a special class of biomolecules present on the cellular membrane. They provide the transport of ions, small molecules, and water in response to internal and external signals, define a cell's immunological identity, and facilitate intra- and intercellular communication. Since they are vital to almost all cellular functions, their mutants, or aberrant expression is linked to many diseases, including cancer, where they are a part of cancer cell-specific molecular signatures and phenotypes.

Fishing against the odds: fishers' motivations to carry on fishing in the wake of the hindering EU Common Fishery Policy-a case study in North Shields, UK.

The UK's fishing industry has contracted considerably since 1972 due to overfishing, increased fuel prices, and implementation of the European Union (EU) Common Fisheries Policy (CFP). Despite this decline affecting the industry at large and the incomes of fishers, some fishers have carried on, or even freshly started or returned to the business. Why have these fishers done so despite the challenges they encounter in the fishing industry? In this article, we investigate why some fishers still choose to fish in the wake of all the EU regulations designed to control overfishing by reducing the size of the industry and discouraging entry by taking measures that affect revenues.

The effectiveness of a low-dose esketamine versus an alfentanil adjunct to propofol sedation during endoscopic retrograde cholangiopancreatography: A randomised controlled multicentre trial.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most complex gastrointestinal endoscopic procedures. Currently, it is still unclear which sedation regimen best facilitates an ERCP. The N-methyl-D-aspartate receptor antagonist esketamine has anaesthetic, analgesic and sympathomimetic properties and is known to cause less cardiorespiratory depression than other sedatives.

Climbing droplets driven by mechanowetting on transverse waves.

Many applications in modern technology, such as self-cleaning surfaces and digital microfluidics, require control over individual fluid droplets on flat surfaces. Existing techniques may suffer from side effects resulting from high electric fields and high temperatures. Here, we introduce a markedly different method, termed "mechanowetting," that is based on the surface tension-controlled droplet motion on deforming surfaces.

Pillars or Pancakes? Self-Cleaning Surfaces without Coating.

Surfaces that stay clean when immersed in water are important for an enormous range of applications from ships and buildings to marine, medical, and other equipment. Up until now the main strategy for designing self-cleaning surfaces has been to combine hydrophilic/hydrophobic coatings with a high aspect ratio structuring (typically micron scale pillars) to trap a (semi)static water/air layer for drag and adhesion reduction. However, such coating and structuring can distort optical properties and get damaged in harsh environments, and contamination, i.

A filter-free blood-brain barrier model to quantitatively study transendothelial delivery of nanoparticles by fluorescence spectroscopy.

The delivery of therapeutics to the brain is greatly hampered by the blood-brain barrier (BBB). The use of nanoparticles that can cross the BBB via the process of receptor-mediated transcytosis at blood-brain barrier endothelial cells seems a promising strategy to transport therapeutics into the brain. To screen for suitable nanocarriers, and to study the process of transcytosis, a cultured polarized monolayer of brain microvascular endothelial cells on an extracellular matrix-coated porous membrane filter is widely used as an in vitro BBB model.

Sedation with propofol during ERCP: is the combination with esketamine more effective and safer than with alfentanil? Study protocol for a randomized controlled trial.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a gastrointestinal procedure that requires a relatively motionless patient during the intervention. Deep sedation by intravenous propofol combined with an opioid has recently become the preferred sedation technique. However, when high doses of propofol are used, side effects, namely respiratory depression, may occur.

Entry of PIP3-containing polyplexes into MDCK epithelial cells by local apical-basal polarity reversal.

The polarized architecture of epithelium presents a barrier to therapeutic drug/gene carriers, which is mainly due to a limited (apical) internalization of the carrier systems. The bacterium Pseudomonas aeruginosa invades epithelial cells by inducing production of apical phosphatidylinositol-3, 4, 5-triphosphate (PIP3), which results in the recruitment of basolateral receptors to the apical membrane. Since basolateral receptors are known receptors for gene delivery vectors, apical PIP3 may improve the internalization of such vectors into epithelial cells.

Anticancer effects of 15d-prostaglandin-J2 in wild-type and doxorubicin-resistant ovarian cancer cells: novel actions on SIRT1 and HDAC.

15-Deoxy-delta-12,14-prostaglandin-J(2) (15d-PGJ(2)), an arachidonic metabolite and a natural PPARγ agonist, is known to induce apoptosis in tumor cells. In this study, we investigated new therapeutic potentials of 15d-PGJ(2) by determining its anticancer effects in wild-type and doxorubicin-resistant ovarian carcinoma cells. Despite high expression of resistance-inducing genes like MDR1, Bcl2 and Bcl-xl, 15d-PGJ(2) strongly induced apoptosis in doxorubicin-resistant (A2780/AD) cells similar to the wild-type (A2780).

Synergistic induction of profibrotic PAI-1 by TGF-β and radiation depends on p53.

Radiation-induced fibrosis is a severe side effect of radiotherapy. TGF-β and radiation synergistically induce expression of the profibrotic PAI-1 gene and this cooperation potentially involves p53. Here, we demonstrate that p53 is both indispensable and sufficient for the radiation effect inducing synergistic activation of PAI-1 by radiation and TGF-β.

A novel approach to deliver anticancer drugs to key cell types in tumors using a PDGF receptor-binding cyclic peptide containing carrier.

Tumor stromal cells have been recently recognized to contribute to tumor growth. Therefore, we hypothesized that delivery of anticancer drugs to these cells in addition to the tumor cells might treat cancer more effectively. Stromal cells abundantly expressed Platelet-Derived Growth Factor Receptor-beta (PDGFR-beta) in different human tumors as shown with immunohistochemistry.

Conformational studies of peptides representing a segment of TM7 from H+-VO-ATPase in SDS micelles.

The conformation of a transmembrane peptide, sMTM7, encompassing the cytoplasmic hemi-channel domain of the seventh transmembrane section of subunit a from V-ATPase from Saccharomyces cerevisiae solubilized in SDS solutions was studied by circular dichroism (CD) spectroscopy and fluorescence spectroscopy of the single tryptophan residue of this peptide. The results show that the peptide adopts an alpha-helical conformation or aggregated beta-sheet depending on the peptide-to-SDS ratio used. The results are compared with published data about a longer version of the peptide (i.

Segment TM7 from the cytoplasmic hemi-channel from VO-H+-V-ATPase includes a flexible region that has a potential role in proton translocation.

A 900-MHz NMR study is reported of peptide sMTM7 that mimics the cytoplasmic proton hemi-channel domain of the seventh transmembrane segment (TM7) from subunit a of H(+)-V-ATPase from Saccharomyces cerevisiae. The peptide encompasses the amino acid residues known to actively participate in proton translocation. In addition, peptide sMTM7 contains the amino acid residues that upon mutation cause V-ATPase to become resistant against the inhibitor bafilomycin.

A monotonic archive for pareto-coevolution.

Coevolution has already produced promising results, but its dynamic evaluation can lead to a variety of problems that prevent most algorithms from progressing monotonically. An important open question therefore is how progress towards a chosen solution concept can be achieved. A general solution concept for coevolution is obtained by viewing opponents or tests as objectives.

Reconstruction of a functional human gene network, with an application for prioritizing positional candidate genes.

Most common genetic disorders have a complex inheritance and may result from variants in many genes, each contributing only weak effects to the disease. Pinpointing these disease genes within the myriad of susceptibility loci identified in linkage studies is difficult because these loci may contain hundreds of genes. However, in any disorder, most of the disease genes will be involved in only a few different molecular pathways.

Ideal evaluation from coevolution.

In many problems of interest, performance can be evaluated using tests, such as examples in concept learning, test points in function approximation, and opponents in game-playing. Evaluation on all tests is often infeasible. Identification of an accurate evaluation or fitness function is a difficult problem in itself, and approximations are likely to introduce human biases into the search process.
