How ligand binds to the type 1 insulin-like growth factor receptor.

Human type 1 insulin-like growth factor receptor is a homodimeric receptor tyrosine kinase that signals into pathways directing normal cellular growth, differentiation and proliferation, with aberrant signalling implicated in cancer. Insulin-like growth factor binding is understood to relax conformational restraints within the homodimer, initiating transphosphorylation of the tyrosine kinase domains. However, no three-dimensional structures exist for the receptor ectodomain to inform atomic-level understanding of these events.

Diagnosis and Treatment of Listeria monocytogenes Endophthalmitis: A Systematic Review.

Purpose: Describe patient characteristics, treatment, and vision outcomes of Listeria monocytogenes endophthalmitis, an exceedingly rare form of listeriosis.

Methods: L. monocytogenes endophthalmitis cases in human adults, located through Medline (32) and from disease surveillance centers (11).

Realising resource efficiency in the management of healthcare waste from the Cornwall National Health Service (NHS) in the UK.

The quantities of waste generated by the healthcare sector in the United Kingdom (UK) have been shown to be amongst the highest in Europe. Based on a case study undertaken within the Cornwall NHS (National Health Service) in the UK, this paper reports on the results of waste minimisation trials. The schemes were able to achieve significant waste reductions in both clinical and domestic waste quantities.

Oxygen initiation of respiration and mitochondrial biogenesis in rice.

Rice growth under aerobic and anaerobic conditions allowed aspects of mitochondrial biogenesis to be identified as dependent on or independent of an oxygen signal. Analysis of transcripts encoding mitochondrial components found that a subset of these genes respond to oxygen (defined as aerobic), whereas others are relatively unaffected by oxygen availability. Mitochondria formed during growth in anaerobic conditions had reduced protein levels of tricarboxylic acid cycle components and cytochrome-containing complexes of the respiratory chain and repressed respiratory functionality.

Healthcare waste management: a case study from the National Health Service in Cornwall, United Kingdom.

This paper looks at steps taken towards the development of a 10-year strategy for the management of healthcare waste from the National Health Service (NHS) in Cornwall, United Kingdom. The major issues and challenges that affect the management of waste by the NHS, including its organisational structure and collection infrastructure, are outlined. The waste flows of the main acute medical site are detailed, using waste audits of domestic and clinical bags, redundant equipment, bulky waste, and special waste.
