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. The

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

Incidental findings and their handling in the Swedish CArdioPulmonary bioimage study (SCAPIS)

The Swedish CArdioPulmonary bioImage Study (SCAPIS) combines the use of new imaging technologies, large-scale proteomics/metabolomics/genomics, and epidemiological analyses to extensively characterize a Swedish cohort of 30,000 men and women aged between 50 and 64 years. Its main aims are to improve risk prediction and to optimize our ability to study mechanisms of cardiopulmonary diseases. SCAPIS
