Intradialytic hypotension (IDH) is common in children during conventional, 4 hour haemodialysis (HD) sessions. The declining blood pressure (BP) was originally believed to be caused by ultrafiltration (UF) and priming of the HD circuit, however emerging data now supports a multifactorial aetiology. Therefore strategies to improve haemodynamic stability need to ...

Many spiders possess myrmecomorphy, and species of the jumping spider genus Myrmarachne exhibit nearly perfect ant mimicry. Most salticids are diurnal predators with unusually high visual acuity that prey on various arthropods, including conspecifics. In this study, we tested whether predation pressure from large jumping spiders is one possible driving ...

There are many theories about why selective inhibitors of the second isoform of cyclooxygenase (COX-2) increase cardiovascular risk. Although torcetrapib raises blood pressure and cardiovascular risk, it has been difficult to prove such a link for COX-2 inhibitors in randomized clinical trials. This review shows a significant correlation in placebo-controlled ...
