Interface Controlled Oxidation States in Layered Cobalt Oxide Nanoislands on Gold

Layered cobalt oxides have been shown to be highly active catalysts for the oxygen evolution reaction (OER; half of the catalytic "water splitting" reaction), particularly when promoted with gold. However, the surface chemistry of cobalt oxides and in particular the nature of the synergistic effect of gold contact are only understood on a rudimentary level, which at present prevents further explor

Transfer of human α-synuclein from the olfactory bulb to interconnected brain regions in mice.

α-Synuclein (α-syn) is a protein prevalent in neural tissue and known to undergo axonal transport. Intracellular α-syn aggregates are a hallmark of Parkinson's disease (PD). Braak and collaborators have suggested that in people who are destined to eventually develop PD, α-syn aggregate pathology progresses following a stereotypic pattern, starting in the olfactory bulb (OB) and the gut. α-Synuclei

Do we know enough? A scientific and ethical analysis of the basis for genetic-based personalized nutrition

This article discusses the prospects and limitations of the scientific basis for offering personalized nutrition advice based upon individual genetic information. Two divergent scientific positions are presented, with an ethical comment. The crucial question is whether the current knowledge base is sufficiently strong for taking an ethically responsible decision to offer personalized nutrition adv

Anisotropic dynamic changes in the pore network structure, fluid diffusion and fluid flow in articular cartilage under compression

A compression cell designed to fit inside an NMR spectrometer was used to investigate the in situ mechanical strain response, structural changes to the internal pore structure, and the diffusion and flow of interstitial water in full-thickness cartilage samples as it was deforming dynamically under a constant compressive load (pressure). We distinguish between the hydrostatic pressure acting on th

Renal stem cells and their implications for kidney cancer.

The renal cell carcinomas (RCC) denote a diverse set of neoplasias with unique genetic and histological features. The RCCs emanate from the renal tubule, a highly heterogeneous epithelial structure, and depending on which cell is malignified the resulting cancer displays unique characteristics. Notwithstanding this, the cells of origin for the RCC forms are far from established, and only inferred

Coupling planktonic and benthic shifts during a bloom of Alexandrium catenella in southern Chile: Implications for bloom dynamics and recurrence

Cell abundances and distributions of Alexandrium catenella resting cysts in recent sediments were studied along time at two locations in the Chilean Inland Sea exposed to different oceanographic conditions: Low Bay, which is much more open to the ocean than the more interior and protected Ovalada Island. The bloom began in interior areas but maximum cyst concentrations were recorded in locations m

Invasive pneumococcal disease in patients with an underlying pulmonary disorder.

Chronic pulmonary disease is a recognized risk factor for invasive pneumococcal disease (IPD). However, previous studies have often not been large enough to allow detailed analyses of less prevalent pulmonary diseases, and findings regarding case fatality have been inconsistent. We examined the associations between an underlying pulmonary disease and IPD, and the impact of these diseases on the ca

How melanism affects the sensitivity of lizards to climate change

The impact of climate change on global biodiversity is firmly established, but the differential effect of climate change on populations within the same species is rarely considered. In ectotherms, melanism (i.e. darker integument due to heavier deposition of melanin) can significantly influence thermoregulation, as dark individuals generally heat more and faster than bright ones. Therefore, darker

Comprehensive analysis of RNA binding motif protein 3 (RBM3) in non-small cell lung cancer

Aims: High expression of the RNA-binding motif protein 3 (RBM3) correlates with improved prognosis in several major types of cancer. The aim of the present study was to examine the prognostic value of RBM3 protein and mRNA expression in non-small cell lung cancer (NSCLC). Methods and results: Immunohistochemical expression of RBM3 was evaluated in surgically treated NSCLC from two independent pati

Nanoscale structural and mechanical characterization of thin bicontinuous cubic phase lipid films

The mechanical response of lipid membranes to nanoscale deformations is of fundamental importance for understanding how these interfaces behave in multiple biological processes; in particular, the nanoscale mechanics of non-lamellar membranes represents a largely unexplored research field. Among these mesophases, inverse bicontinuous cubic phase QII membranes have been found to spontaneously occur

Involvement of the tumor suppressor gene p53 in tumor necrosis factor-induced differentiation of the leukemic cell line K562

The cDNA of the human wild-type p53 tumor suppressor gene was constitutively overexpressed in the leukemic cell line K562 (which lacks detectable amounts of p53 protein) in order to investigate the consequences for growth and differentiation. Several stable clones were established by transfection of the expression vector pc53SN3. Expression of p53 protein was characterized by biosynthetic labeling

The cardiorenal syndrome: Structural and functional aspects including associations with the shrunken pore syndrome

Mild to moderate renal impairment affects 10% of the general population. Renal impairment is difficult to detect because of the lack of symptoms, but it can be estimated by calculating the estimated glomerular filtration rate (eGFR) on the basis of plasma creatinine and/or cystatin C concentrations. Chronic kidney disease (CKD) is associated with an increased risk of development of cardiovascular

Workplace incivility and bystanders’ helping intentions

Purpose: Using observational and experimental designs, the purpose of this study was to explore if the power relation between the offender and the victim of incivility and the level of perceived severity of the incivility were associated with bystanders’ intentions to help when witnessing workplace incivility. Design/methodology/approach: In Study 1, 160 participants completed a questionnaire wher

Multipotent Adult Progenitor Cells suppress homeostatic driven activation of T cells in vivo

In the setting of transplantation, T cells are deliberately depleted to prevent allograft rejection. However, this IL-7 activates the accelerated proliferation of effector memory T cells, which are the predominant mediators of graft rejection. Multipotent adult progenitor cells (MAPC) have been previously shown to modulate the response of T cells to IL-7, in vitro but not in vivo. Here, for the fi
