Theophylline is able to partially revert cachexia in tumour-bearing rats

UNLABELLED: BACKGROUND AND AIMS: The aim of the present investigation was to examine the anti-wasting effects of theophylline (a methylxantine present in tea leaves) on a rat model of cancer cachexia.METHODS: The in vitro effects of the nutraceuticals on proteolysis were examined on muscle cell cultures submitted to hyperthermia. Individual muscle weights, muscle gene expression, body composition

Patterns of gene expression in muscle and fat in tumor-bearing rats : effects of CRF2R agonist on cachexia

The hypothesis we tested was that administering corticotropin-releasing factor receptor agonists preserves muscle mass during cancer that is related to changes in tissue gene expression. cDNA microarrays were used to compare mRNAs from muscle and adipose tissues of non-treated and agonist-treated tumor-bearing rats. In muscle of non-tumor-bearing agonist-treated animals we observed decreased expre

Towards a framework for holistic contextual design for low-resource settings

Healthcare inequality is ubiquitous globally, but the effects are most striking in low-resource settings. In these settings, current methods for the design of medical devices are failing to address specific needs. The associated publications rarely describe how the context was studied at the front-end of design. There is a latent need for a holistic contextual framework for guiding the design deci

Influence of physical properties of phases on hydrodynamics and mass transfer characteristics of a liquid-liquid circular microchannel

The influences of operating conditions and physical properties of the two phases on the hydrodynamics and mass transfer in a circular liquid-liquid microchannel have been investigated. The polytetrafluoroethylene (PTFE) microchannel has an internal diameter of 0.7 mm and a T-shaped mixing junction. Sodium hydroxide solution was used as the aqueous phase. N-hexane and toluene were employed as the o

Effect of entrainment on liquid film dryout in vertical upward annular flow

This work aims to investigate the effect of liquid entrainment on liquid film dryout in annular flow for flow boiling. Entrainment and deposition rates of droplets were included in mass conservation equations to estimate the local liquid film mass flux in annular flow, and the critical vapor quality at dryout conditions. Different entrainment rate correlations were evaluated using flow boiling dat

Regulating a global value chain with the European Union's sustainability criteria – experiences from the Swedish liquid transport biofuel sector

Despite promises that they can contribute toward more environmentally beneficial transportation there are many sustainability concerns about liquid transport biofuels. In response to pressure from civil society, the European Union (EU) has introduced sustainability criteria for biofuels. A hybrid regulatory system involving state and non-state actors stipulates that retailers and producers must co

SMIM1 variants rs1175550 and rs143702418 independently modulate Vel blood group antigen expression

The Vel blood group antigen is expressed on the red blood cells of most individuals. Recently, we described that homozygosity for inactivating mutations in SMIM1 defines the rare Vel-negative phenotype. Still, Vel-positive individuals show great variability in Vel antigen expression, creating a risk for Vel blood typing errors and transfusion reactions. We fine-mapped the regulatory region located

White to beige conversion in PDE3B KO adipose tissue through activation of AMPK signaling and mitochondrial function

Understanding mechanisms by which a population of beige adipocytes is increased in white adipose tissue (WAT) reflects a potential strategy in the fight against obesity and diabetes. Cyclic adenosine monophosphate (cAMP) is very important in the development of the beige phenotype and activation of its thermogenic program. To study effects of cyclic nucleotides on energy homeostatic mechanisms, mic

Conduction Band Offset and Polarization Effects in InAs Nanowire Polytype Junctions

Although zinc-blende (ZB) and wurtzite (WZ) structures differ only in the atomic stacking sequence, mixing of crystal phases can strongly affect the electronic properties, a problem particularly common to bottom up-grown nanostructures. A lack of understanding of the nature of electronic transport at crystal phase junctions thus severely limits our ability to develop functional nanowire devices. I

Interfacial Structures of Trihexyltetradecylphosphonium-bis(mandelato)borate Ionic Liquid Confined between Gold Electrodes

Atomistic molecular dynamics simulations have been performed to study microscopic the interfacial ionic structures, molecular arrangements, and orientational preferences of trihexyltetradecylphosphonium-bis(mandelato)borate ([P6,6,6,14][BMB]) ionic liquid confined between neutral and charged gold electrodes. It was found that both [P6,6,6,14] cations and [BMB] anions are coabsorbed onto neutral el

Reduction of Abeta amyloid pathology in APPPS1 transgenic mice in the absence of gut microbiota

Alzheimer's disease is the most common form of dementia in the western world, however there is no cure available for this devastating neurodegenerative disorder. Despite clinical and experimental evidence implicating the intestinal microbiota in a number of brain disorders, its impact on Alzheimer's disease is not known. To this end we sequenced bacterial 16S rRNA from fecal samples of Aβ precurso

Relating ICT to organizational change in research and practice

The topic of ICT-enabled organizational change has been a focus of attention in information systems (IS) research for decades. Besson and Rowe (J Strateg Inf Syst 21:103-124, 2012 [17]), however, have identified a lack of description and conceptualization of the transformation process in the main stream of IS research. This paper discusses key IS paradigms in some of the content of commonly and av

The Long Run Behavior of the Income Velocity of Money in Five Advanced Countries, 1870-1976 : An Institutional Approach

The income velocity of money in Canada, the United States, Great Britain, Norway and Sweden displays a U-shaped pattern over the last one hundred years. This paper presents and tests empirically an explanation for this secular pattern emphasizing the influence on velocity of institutional changes. The inclusion into a simple velocity function of institutional developments such as the process of mo

In search of “Muda” through the TKJ diagram

Purpose: Muda is a Japanese term literally meaning futility, uselessness, idleness, superfluity, waste, wastage or wastefulness. The term was introduced by the Japanese engineer Taiichi Ohno of Toyota Motor Corporation in the 1960s. Therefore, reducing and minimizing Muda is an effective way to increase the operational efficiency and productivity of an organization’s processes. In turn, the techni
