"NDR: Prototype of National Dose Register for Latin America. Main experiences in their design and implementation".

J Radiol Prot 2021 May 5. Epub 2021 May 5.

Department of Nuclear Safety and Security, International Atomic Energy Agency, Vienna, AUSTRIA.

Several national regulations and good international practices promote the existence of a central register with the results of individual radiological monitoring. In the majority of the countries (Latin American region), dosimetry data were neither harmonized, nor managed by a unique database, therefore the possibility of using such data, for proper characterization of the radiological conditions, integrally at national level, in a territory or a sector, and by practices or occupational categories, was very limited. All these considerations justified the need for developing a prototype of National Dose Register (NDR) for Latin America. Read More

Odor sampling strategies in mice with genetically altered olfactory responses.

PLoS One 2021 3;16(5):e0249798. Epub 2021 May 3.

Princeton Neuroscience Program, Princeton University, Princeton, NJ, United States of America.

Peripheral sensory cells and the central neuronal circuits that monitor environmental changes to drive behaviors should be adapted to match the behaviorally relevant kinetics of incoming stimuli, be it the detection of sound frequencies, the speed of moving objects or local temperature changes. Detection of odorants begins with the activation of olfactory receptor neurons in the nasal cavity following inhalation of air and airborne odorants carried therein. Thus, olfactory receptor neurons are stimulated in a rhythmic and repeated fashion that is determined by the breathing or sniffing frequency that can be controlled and altered by the animal.
