Living on the edge: precariousness and why it matters for health
The post-war period in Europe, between the late 1940s and the 1970s, was characterised by an expansion of the role of by the state, protecting its citizens from risks of unemployment, poverty, homelessness, and food insecurity. This security began to erode in the 1980s as a result of privatisation and deregulation. The withdrawal of the state further accelerated after the 2008 financial crisis, as countries began pursuing deep austerity. The result has been a rise in what has been termed âprecariousnessâ. Here we review the development of the concept of precariousness and related phenomena of vulnerability and resilience, before reviewing evidence of growing precariousness in European countries. It describes a series of studies of the impact on precariousness on health in domains of employment, housing, and food, as well as natural experiments of policies that either alleviate or worsen these impacts. It concludes with a warning, drawn from the history of the 1930s, of the political consequences of increasing precariousness in Europe and North America
Insights into APC/C: from cellular function to diseases and therapeutics
Anaphase-promoting complex/cyclosome (APC/C) is a multifunctional ubiquitin-protein ligase that targets different substrates for ubiquitylation and therefore regulates a variety of cellular processes such as cell division, differentiation, genome stability, energy metabolism, cell death, autophagy as well as carcinogenesis. Activity of APC/C is principally governed by two WD-40 domain proteins, Cdc20 and Cdh1, in and beyond cell cycle. In the past decade, the results based on numerous biochemical, 3D structural, mouse genetic and small molecule inhibitor studies have largely attracted our attention into the emerging role of APC/C and its regulation in biological function, human diseases and potential therapeutics. This review will aim to summarize some recently reported insights into APC/C in regulating cellular function, connection of its dysfunction with human diseases and its implication of therapeutics
Auditory event-related potentials
Auditory event related potentials are electric potentials (AERP, AEP) and magnetic fields (AEF) generated by the synchronous activity of large neural populations in the brain, which are time-locked to some actual or expected sound event
Evidence of Clostridium perfringens epsilon toxin associated with multiple sclerosis.
BACKGROUND: It was recently reported that, using Western blotting, some multiple sclerosis (MS) patients in the United States had antibodies against epsilon toxin (Etx) from Clostridium perfringens, suggesting that the toxin may play a role in the disease. OBJECTIVE: We investigated for serum antibodies against Etx in UK patients with clinically definite multiple sclerosis (CDMS) or presenting with clinically isolated syndrome (CIS) or optic neuritis (ON) and in age- and gender-matched controls. METHODS: We tested sera from CDMS, CIS or ON patients or controls by Western blotting. We also tested CDMS sera for reactivity with linear overlapping peptides spanning the amino acid sequence (Pepscan) of Etx. RESULTS: Using Western blotting, 24% of sera in the combined CDMS, CIS and ON groups ( nâ=â125) reacted with Etx. In the control group ( nâ=â125), 10% of the samples reacted. Using Pepscan, 33% of sera tested reacted with at least one peptide, whereas in the control group only 16% of sera reacted. Out of 61 samples, 21 (43%) were positive to one or other testing methodology. Three samples were positive by Western blotting and Pepscan. CONCLUSION: Our results broadly support the previous findings and the role of Etx in the aetiology of MS warrants further investigation.This work was supported by the MS Sciences Ltd and by the NIHR Exeter CRF
Water quality of Loch Leven: responses to enrichment, restoration and climate change
It is usually assumed that climate change will have negative impacts on water quality and hinder restoration
efforts. The long-term monitoring at Loch Leven shows, however, that seasonal changes in temperature and
rainfall may have positive and negative impacts on water quality. In response to reductions in external nutrient
loading, there have been significant reductions in in-lake phosphorus concentrations. Annual measures of
chlorophyll a have, however, shown little response to these reductions. Warmer spring temperatures appear
to be having a positive effect on Daphnia densities and this may be the cause of reduced chlorophyll a
concentrations in spring and an associated improvement in water clarity in May and June. The clearest climate
impact was the negative relationship between summer rainfall and chlorophyll a concentrations. This is
highlighted in extreme weather years, with the three wettest summers having very low chlorophyll a
concentrations and the driest summers having high concentrations. To predict water quality impacts of future
climate change, there is a need for more seasonal predictions from climate models and a greater recognition
that water quality is the outcome of seasonal responses in different functional groups of phytoplankton and
zooplankton to a range of environmental drivers
