How Dangerous Is the Sodium Cyanide at the Tianjin Explosion Site?This chemical has a particularly unpleasant reputation, but if officials act fast, they should be able to limit its impactBenjamin BurkeThe Conversation UK
Why is high blood pressure dangerous?Strokes:A stroke can make the brain cells necrotic due to a decreased blood supply as a result of blockage or rupture in an artery in the brain. The most common symptoms of a person who is having a stroke are sudden weakness, slurred speech, and ...
Sodium, a chemical found in salt, raises blood pressure by promoting the retention of fluid by the body. This increases the workload on the heart. The American Heart Association recommends an upper daily limit for sodium consumption of 1,500 mg. Checking food labels and menus can help you c...
Kazachia 112, Saratov, 410026, Russia Introduction: The problem of treating the coagulate disor- ders in cases of gestosis remains of topical interest in obstetrics; heparin is dangerous because of the possible development of thrombocytopenia, heparin-induced throm- bosis, osteoporosis, and increased...

120 D. 140 E. None of the above. Compare hypertension and the transient increase in blood pressure caused by exercise. Fill in the blank. ___ causes increased sodium retention and increased blood pressure. Discuss the factors that affect blood flow in the vasculature and their relationship to...
Voltage-gated sodium currents were elicited in whole-cell voltage-clamp by voltage steps from -120 mV to 0 mV in the absence (control, black), presence (drug, red), and after washout (recovery, blue) of 500 nM TTX (scale bar, 10 nA and 25 ms). (b) The electrophysiological recording...
The column was an ET 125/2, Nucleosil 120-5, C-18 reversed phase column (Macherey–Nagel, Düren, Germany) perfused with a mobile phase composed of 75 mM NaH2PO4, 4 mM KCl, 20 μM ethylenediamine tetraacetic acid, 1.5 mM sodium dodecyl sulfate, 100 μl l − 1 diethylamine, 12% ...
Motile and non-motile cilia are associated with mutually-exclusive genetic disorders. Motile cilia propel sperm or extracellular fluids, and their dysfunction causes primary ciliary dyskinesia. Non-motile cilia serve as sensory/signalling antennae on mos
(sylvin). A substitution process often takes place between potassium and sodium, which have geochemically similar properties, in the minerals. Potassium has three isotopes, of which only40K is radioactive and occurs with a relative abundance of 0.012% (Plant and Saunders1996) and a half-life ...
