Abnormally low plasma concentrations of thyroid hormones during sepsis often occur in the absence of thyroidal illness; however, the mechanisms involved in the "euthyroid sick syndrome" remain poorly understood. Here, we describe a previously unrecognized interaction between the thyroid hormone thyroxine (T(4)) and the proinflammatory cytokine macrophage migration inhibitory factor (MIF), toget...

The olfactory recess - a blind pocket at the back of the nasal airway - is thought to play an important role in mammalian olfaction by sequestering air outside of the main airstream, thus giving odorants time to re-circulate. Several studies have shown that species with large olfactory recesses tend to have a well-developed sense of smell. However, no study has investigated how the size of the ...
Computational Fluid Dynamics (CFD) investigations into water entry problems of a rigid flat plate with air pockets were systematically conducted. The Volume (VOF) model was utilised to capture localised slamming phenomena that occur during, and post-impact events. model's geometry modified include pocket on the impact surface investigate effect entrapment magnitude distribution forces pressures...
Avalanches are one of the major threats to life in high mountain terrain. Once buried by an avalanche, survival chances dramatically drop from 92% after 15 minutes to only 30% after 35 minutes mostly due to the lack of oxygen. It is therefore extremely important to rescue any victims as fast as possible in order to maximize survival chances. Today’s technology, so called electronic avalanche be...
Burden of poor oral health in older age: findings from a population-based study of older British men
OBJECTIVES Evidence of the extent of poor oral health in the older UK adult population is limited. We describe the prevalence of oral health conditions, using objective clinical and subjective measures, in a population-based study of older men. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS A representative sample of men aged 71-92 years in 2010-2012 from the British Regional Heart ...
Methylene blue (MB)- or Curcumin (Cur)-based photodynamic therapy (PDT) has been used as an adjunctive treatment for periodontitis. Its actual clinical efficacy is still in question because the lack of oxygen a deep periodontal pocket might reduce PDT efficacy. We aim to investigate effect on and examine if addition hydrogen peroxide (HP) could improve performance anaerobically. To this end, we...
