Retinal Glial (Müller) Cells : Sensing and responding to tissue stretch
Purpose. To test whether Müller glial cells sense, and respond to, mechanical tension in the retina. Methods. A device was designed to stretch the retina at right angles to its surface, across retinal layers. Pieces of retina were mounted between two hollow tubes, and uniaxial force was applied to the tissue using a micrometer-stepping motor. Müller cells were selectively stained with the fluoresc
Inheritance of acquired behaviour adaptations and brain gene expression in chickens
Background: Environmental challenges may affect both the exposed individuals and their offspring. We investigated possible adaptive aspects of such cross-generation transmissions, and hypothesized that chronic unpredictable food access would cause chickens to show a more conservative feeding strategy and to be more dominant, and that these adaptations would be transmitted to the offspring. Methodo
Extremely different behaviours in high and low body weight lines of chicken are associated with differential expression of genes involved in neuronal plasticity
Long-term selection (>45 generations) for low or high body weight from the same founder population has generated two extremely divergent lines of chickens, the low (LWS) and high weight (HWS) lines, which at the age of selection (56days) differs by more than nine-fold in body weight. The HWS line chickens are compulsive feeders, whereas, in the LWS line, some individuals are anorexic and others ha
Room-temperature InP/InAsP Quantum Discs-in-Nanowire Infrared Photodetectors
The possibility to engineer nanowire heterostructures with large bandgap variations is particularly interesting for technologically important broadband photodetector applications. Here we report on a combined study of design, fabrication, and optoelectronic properties of infrared photodetectors comprising four million n+–i–n+ InP nanowires periodically ordered in arrays. The nanowires were grown b
Optimization of Current Injection in AlGaInP Core−Shell Nanowire Light-Emitting Diodes
Core–shell nanowires offer great potential to enhance the efficiency of light-emitting diodes (LEDs) and expand the attainable wavelength range of LEDs over the whole visible spectrum. Additionally, nanowire (NW) LEDs can offer both improved light extraction and emission enhancement if the diameter of the wires is not larger than half the emission wavelength (λ/2). However, AlGaInP nanowire LEDs h
Brand Equity and the Brand Value Chain : What it is and How to Use it in Practice
Many brand managers have long since established the desired core values for their brand, but are still not sure whether they differentiate themselves enough from their most daunting competitors, and whether their brand actually helps to boost sales of their products. This chapter describes a basic brand equity framework for understanding how brand management can create customer value and sharehold

Rural Livelihood Diversification in Sub-Saharan Africa: A Literature Review
This article provides a comprehensive review of the literature on the nature and evolution of rurallivelihood diversification in sub-Saharan Africa, and the situation regarding smallholders. It reveals mixedfindings about the causes and consequences of livelihood diversification on rural smallholders adopting thisstrategy. A lot of evidence from the literature suggests that it is relatively better
Patterns and Determinants of Household Income Diversification in Rural Senegal and Kenya
Income diversification is considered one of the important household strategies for securing rural livelihoods. We investigate its patterns and determinants using data on 1,747 farm households collected in 2007-2008 from six regions in rural Senegal and Kenya. The empirical investigation shows that the regional variation in income diversification does not follow any clear patterns, with push and pu
Household Livelihood Diversification and Gender: Panel Evidence from Rural Kenya
There are high hopes that livelihood diversification could contribute to goals of poverty reduction in Sub-Saharan Africa (SSA). This study uses household panel data collected in 2008 and 2013, combined with a mixed methodology to examine the regional and gender disparities, as well as the determinants of change in livelihood diversification in the regions of Nyeri and Kakamega in rural Kenya.

Deletion of ribosomal protein genes is a common vulnerability in human cancer, especially in concert with TP53 mutations
Heterozygous inactivating mutations in ribosomal protein genes (RPGs) are associated with hematopoietic and developmental abnormalities, activation of p53, and altered risk of cancer in humans and model organisms. Here we performed a large-scale analysis of cancer genome data to examine the frequency and selective pressure of RPG lesions across human cancers. We found that hemizygous RPG deletions
Global binding pattern of the Wilms' tumor gene 1 (WT1) +17AA -KTS isoform in leukemic cells
The aim of this study was to investigate the global DNA-binding pattern of Wilms' tumor gene 1 (WT1) in leukemic cells. Clinical and preclinical data indicate the zinc finger transcription factor WT1 as an oncogene, but the full target gene repertoire of WT1 in leukemic cells has not been previously characterized. The -KTS isoforms (excluding the three amino acid (KTS) insert between zinc finger t
