REVIEW
Tatsuro Nakamura, Takahisa Murata
Anaphylaxis is a life-threatening type I allergic reaction. Antigen-antibody complexes lead mast cells, basophils, and neutrophils to release large amounts of histamine and/or platelet activating factor (PAF). These mediators induce hypotension and vascular hyperpermeability and subsequent anaphylaxis dependent on the endothelial production of NO. Here, we have summarised previous studies reporting the mechanisms underlying the functional changes within the vasculature, specifically focusing on vascular permeability triggered by histamine or PAF...

Background: Effects of nonparoxysmal atrial fibrillation (non-PAF) ablation targeting complex fractionated atrial electrogram (CFAE) areas and/or low voltage areas (LVAs) are still controversial. Methods and Results: A recently developed online real-time phase mapping system (ExTRa Mapping) was used to conduct LVA mapping and simultaneous ExTRa and CFAE mapping in 28 non-PAF patients after pulmonary vein isolation (PVI). Nonpassively activated areas, in the form of meandering rotors and/or multiple wavelets assumed to contain non-PAF drivers, partly overlapped with CFAE/LVAs but not always coincided with them...

BACKGROUND: Body mass index (BMI) has been constantly increasing over the last decades in most parts of the world, most notably in transitioning nations such as Brazil. High BMI (>22 kg/m2 ) is associated with an increased risk of 14 types of cancer. We estimated the extent to which reducing high BMI could lower cancer incidence in Brazil, nationally as well as at regional and state levels. METHODS: We calculated fractions of cancer incidence in 2012 attributable to high BMI as well as projections for attributable cases in 2025 using BMI data from representative national surveys and relative risks published in meta-analyses...

A porous aromatic framework of type PAF-6 was synthesized and explored as a coating onto a steel wire for using in solid-phase microextraction of polycyclic aromatic hydrocarbons (PAHs), phthalate plasticizers, and n-alkanes. The extraction temperature, extraction time, salt concentration, agitation speed, desorption temperature, and desorption time were optimized. This method for SPME resulted in the enrichment factors ranging from 122 to 1090 for PAHs (naphthalene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene), from 122 to 271 for plasticizers (diisobutyl phthalate, dibutyl phthalate, benzyl butyl phthalate, dicyclohexyl phthalate), and from 9 to 113 for n-alkanes (n-undecane, n-dodecane, n-tridecane, n-tetradecane, n-pentadecane, n-hexadecane, n-octadecane and n-eicosane)...

The cellular prion protein (PrPC ) acts as a scaffold protein that organises signalling complexes. In synaptosomes, the aggregation of PrPC by amyloid-β (Aβ) oligomers attracts and activates cytoplasmic phospholipase A2 (cPLA2 ) leading to synapse degeneration. The signalling platform is dependent upon cholesterol released from cholesterol esters by cholesterol ester hydrolases (CEH)s. The activation of CEHs depends upon activated cPLA2 and platelet activating factor (PAF) demonstrating a positive feedback system, activated cPLA2 increased cholesterol concentrations, which in turn facilitated cPLA2 activation...

BACKGROUND: Changing population-level exposure to modifiable risk factors is a key driver of changing cancer incidence. Understanding these changes is therefore vital when prioritising risk-reduction policies, in order to have the biggest impact on reducing cancer incidence. UK figures on the number of risk factor-attributable cancers are updated here to reflect changing behaviour as assessed in representative national surveys, and new epidemiological evidence. Figures are also presented by UK constituent country because prevalence of risk factor exposure varies between them...
