Quality and safety are rarely simple.
I live on an island 70 miles from Boston. I occasionally travel to the US mainland by ferry, but more often via a small airline with nine-passenger planes that are usually flown by a solitary pilot. The pilot’s preflight checklist is a small plastic card, usually reviewed in a matter of seconds—arguably, a simple task. One checklist item is to assure that the flaps are retracted, unlike jetline...
متن کاملChloride channels: often enigmatic, rarely predictable.
Until recently, anion (Cl(-)) channels have received considerably less attention than cation channels. One reason for this may be that many Cl(-) channels perform functions that might be considered cell-biological, like fluid secretion and cell volume regulation, whereas cation channels have historically been associated with cellular excitability, which typically happens more rapidly. In this r...

Patients who recei...
متن کاملDopamine Transporter Is Rarely Endocytosed in Striatum
The dopamine transporter (DAT) limits the spatial and temporal spread of dopaminergic signaling by taking up extracellular dopamine. This function is thought to be modulated by endogenous signaling pathways. For example, phosphorylation of DAT by protein kinase C (PKC) reduces dopamine uptake, whereas phosphorylation by extracellular signal-regulated kinase increases uptake. Although phosphoryl...
