Fatal fluorosilicic acid exposure after a motor vehicle crash: a case report - Yorke JA, McNaughton-Filion L, Herath JC.
Fluorosilicic acid (FSA) is a corrosive liquid used in manufacturing and other processes. High-level exposures to FSA cause fluoride toxicity resulting in profound hypocalcemia, potentially leading to sudden death. Prompt recognition of exposure risk allow... (Source: SafetyLit)

A short de novo synthesis of nucleoside analogs
We present a process for rapidly constructing nucleoside analogs from simple achiral materials. Using only proline catalysis, heteroaryl-substituted acetaldehydes are fluorinated and then directly engaged in enantioselective aldol reactions in a one-pot reaction. A subsequent intramolecular fluoride displacement reaction provides a functionalized nucleoside analog. The versatility of this process is highlighted in multigram syntheses of d- or l-nucleoside analogs, locked nucleic acids, iminonucleosides, and C2'- and C4'-modified nucleoside analogs. This de novo synthesis creates opportunities for the preparation of diversi...

Effects of desensitizing products on the reduction of pain sensitivity caused by in-office tooth bleaching: a 24-week follow-up
Conclusion Our results indicate that adding NF/S, NA/S, NF/AC, and NA/AC desensitizers to tooth bleaching protocols reduces pain sensitivity without affecting its effectiveness. (Source: Dental Technology Blog)

Comparison of two caries prevention programs among Thai kindergarten: a randomized controlled trial
ConclusionsThe negligible difference in caries increment between the HRI and HRB groups implies that intensified prevention produced minimal additional benefit. Offering all children only basic prevention could have obtained virtually the same preventive effect with substantially less effort and lower cost. (Source: Dental Technology Blog)

What Causes Tachycardia?
Discussion
Tachycardia is a rapid heart rate that is above normal for age and level of exertion. Tachycardia is common, particularly sinus tachycardia due to normally encountered circumstances such as pain, fever or exercise. It is usually a normal physiologic process but sustained tachycardia often indicates a potentially abnormal underlying cause.
Sinus tachycardia has a rapid heart rate with normal P waves and P-R intervals and variations from moment to moment and respiration. Generally it is not over 200 beats/minute. Vagal stimulation can slow the heart rate; this is a gradual slowing, not an abrupt slowing seen in ...
