Axonal damage, a core feature of neurological diseases, induces a retrograde reaction in neurons and surrounding glia. We determined transcriptional profiles of this reaction using Affymetrix oligonucleotide arrays. Gene expression was examined in spinal cord tissue prior to injury and following ventral root avulsion in two inbred rat strains, where the degree of neurodegeneration differs. Stringe

We describe the molecular characterization of the Drosophila gene tenm, a large transcription unit spanning > 110 kb of DNA. tenm encodes a large extracellular protein of 2515 amino acids related to the extracellular matrix molecule tenascin. The Tenm protein is found in seven stripes during the blastoderm stage, and each stripe overlaps with the even-skipped stripes. tenm mutants show a phenotype

Glucagon receptor (Gcgr) signaling maintains hepatic glucose production during the fasting state; however, the importance of the Gcgr for lipid metabolism is unclear. We show here that fasted Gcgr-/- mice exhibit a significant increase in hepatic triglyceride secretion and fasting increases fatty acid oxidation (FAO) in wild-type (WT) but not in Gcgr-/- mice. Moreover fasting upregulated the expre

Resting barley (Hordeum vulgare L.) grains contain acid-proteinase activity. The corresponding enzyme was purified from grain extracts by affinity chromatography on a pepstatin-Sepharose column. The pH optimum of the affinity-purified enzyme was between 3.5 and 3.9 as measured by hemoglobin hydrolysis and the enzymatic activity was completely inhibited by pepstatin a specific inhibitor of aspartic

In this paper, we aim to contribute to an enhanced theoretical ground for Universal Design (UD) by examining the concept of “inclusion”, presenting a conceptual critique of it based on our research on categorisation and UD, and proposing a way forward. This study is based on a comprehensive analysis of a range of photographs related to inclusion and exclusion collected during five recent research

The breakdown of relations between China and the US has prompted Beijing to shore up existing friendships, and seek new ones.

Every year, the world adds more renewable energy production capacity than the year before. But, looking historically, is this growth enough to achieve our climate targets? According to a recent publication in ‘Nature Energy’, the short answer is “no” – to meet the climate goals requires decades of growth in renewables at rates higher than those observed historically in most countries. In this epis

Exhaled SARS-CoV-2-containing aerosols contributed significantly to the rapid and vast spread of covid-19. However, quantitative experimental data on the infectivity of such aerosols is missing. Here, we quantified emission rates of infectious viruses in exhaled aerosol from individuals within their first days after symptom onset from covid-19. Six aerosol samples from three individuals were cultu

Attention deficit hyperactivity disorder (ADHD) is the most prevalent neuropsychiatric disorder in the world. Currently, the diagnosis is based mainly on interviews, resulting in uncertainties in the clinical assessment. While some neuropsychological tests are used, their specificity and selectivity are low, and more reliable biomarkers are desirable. Previous research indicates that ADHD is assoc

PRDM (PRDI-BF1 and RIZ homology domain containing) family members are sequence-specific transcriptional regulators involved in cell identity and fate determination, often dysregulated in cancer. The PRDM15 gene is of particular interest, given its low expression in adult tissues and its overexpression in B-cell lymphomas. Despite its well characterized role in stem cell biology and during early de

Rewetting dry soil induces enormous changes in microbial growth and biogeochemistry. Upon drying-rewetting (D/RW), bacteria have been shown to exhibit two different responses: (1) a more resilient response where bacteria start growing immediately with a quick recovery after rewetting and (2) a less resilient response where there is a pronounced lag-period before bacterial growth starts to increase

The efforts to measure people’s current preferences and values of ecosystem services raise questions about the link to sustainability transformations. The importance of taking social and cultural values of nature into account is increasingly recognised within ecosystem services research and policy. This notion is informing the development and application of social (or socio-cultural) valuation met

Fatal intoxications with opioids are known to be associated with an increased lung weight, as well as with brain and pulmonary edema and urinary retention. However, there is evidence to suggest that fatal intoxications with non-opioid substances are also associated with increased lung weight; however, the latter aspect has not been comprehensively analyzed. To determine to what extent opioid and n
