Fluorescence Turns on‐off‐on Sensing of Ferric Ion and L‐Ascorbic Acid by Carbon Quantum Dots

Journal of Food Quality, Volume 2023, Issue 1, 2023., 2023
This study used a hydrothermal approach to create a sensitive and focused nanoprobe. Using an “on‐off‐on” sensing mechanism, the nanoprobe was employed to detect and quantify ferric ions and L‐ascorbic acid. Synthesis of the carbon quantum dots was achieved with a single hydrothermal step at 180°C for 24 hours using hot pepper as the starting material.

Engineering vanilloid-sensitivity into the rat TRPV2 channel

eLife, 2016
The TRPV1 channel is a detector of noxious stimuli, including heat, acidosis, vanilloid compounds and lipids. The gating mechanisms of the related TRPV2 channel are poorly understood because selective high affinity ligands are not available, and the ...

Co‐expression networks of deacclimation‐impaired transcription factor mutants identified complex regulation of the cold stress release response

Physiologia Plantarum, Volume 174, Issue 4, July/August 2022., 2022
Abstract Plants adapt to cold, non‐freezing temperatures through cold acclimation and lose acquired freezing tolerance in warmer temperatures in a process called deacclimation. This work identified a hypoxia response during early deacclimation evidenced by increased ADH activity and upregulated gene expression of hypoxia markers.

Structural insights into the mechanism of activation of the TRPV1 channel by a membrane-bound tarantula toxin

eLife, 2016
Venom toxins are invaluable tools for exploring the structure and mechanisms of ion channels. Here, we solve the structure of double-knot toxin (DkTx), a tarantula toxin that activates the heat-activated TRPV1 channel. We also provide improved structures

TRPV3 in skin thermosensation and temperature responses. [PDF]

J Physiol Sci
Human skin, as a sophisticated sensory organ, is able to detect subtle changes in ambient temperature. This thermosensory capability is primarily mediated by temperature-sensitive TRP channels expressed in both sensory neurons and keratinocytes. Among these, TRPV3, which responds to warm temperatures and plays a crucial role in various skin functions ...

The Cellular Code for Mammalian Thermosensation [PDF]

The Journal of Neuroscience, 2013
Mammalian somatosenory neurons respond to thermal stimuli and allow animals to reliably discriminate hot from cold and to select their preferred environments. Previously, we generated mice that are completely insensitive to temperatures from noxious cold to painful heat (−5 to 55°C) by ablating several different classes of nociceptor early in ...

Injury Threshold of Oral Contact with Hot Foods and Method for Its Sensory Evaluation

Safety, 2018
Epidemiological studies indicate an increased risk of esophageal cancer from the consumption of very hot foods and beverages. The contact time and the contact temperature are decisive for the risk of injury.

Plant Thermomorphogenesis: Identifying Plant Thermosensors [PDF]

, 2020
Plants are subjugated to fluctuations in temperature over daily and seasonal temporal scales. Because of their sessile nature, plants have evolved necessary physiological response pathways to temperature fluctuations in order to adapt to their ...

Transmembrane Prolines Mediate Signal Sensing and Decoding in Bacillus subtilis DesK Histidine Kinase

mBio, 2019
Environmental awareness is an essential attribute of all organisms. The homeoviscous adaptation system of Bacillus subtilis provides a powerful experimental model for the investigation of stimulus detection and signaling mechanisms at the molecular level.

A brief history of Thermosense [PDF]

Thermosense: Thermal Infrared Applications XL, 2018
The first Thermosense Conference held at the Chattanooga Choo-Choo Hotel in 1978 was in response to the “Carter Energy Crisis”. There were three sessions with a total of fifteen papers presented. The sessions all dealt with IR thermography with the first devoted to building heat loss, the second giving case studies and the third devoted to progress ...
