The secreted autotransporter toxin (Sat) does not act as a virulence factor in the probiotic Escherichia coli strain Nissle 1917 [PDF]

, 2015
BACKGROUND: Escherichia coli Nissle 1917 (EcN) is a probiotic used in the treatment of intestinal diseases. Although it is considered safe, EcN is closely related to the uropathogenic E.

RETINOBLASTOMA‐RELATED Has Both Canonical and Noncanonical Regulatory Functions During Thermo‐Morphogenic Responses in Arabidopsis Seedlings

Plant, Cell &Environment, Volume 48, Issue 2, Page 1217-1231, February 2025.
ABSTRACT Warm temperatures accelerate plant growth, but the underlying molecular mechanism is not fully understood. Here, we show that increasing the temperature from 22°C to 28°C rapidly activates proliferation in the apical shoot and root meristems of wild‐type Arabidopsis seedlings.

Heat application in live cell imaging

FEBS Open Bio, Volume 14, Issue 12, Page 1940-1954, December 2024.
Thermal modulation in live‐cell imaging with a high spatiotemporal resolution allows the investigation of biomolecular reactions like protein deactivation and unfolding, and cellular processes like calcium signaling. Local changes in temperature are induced via infrared (IR) irradiation of water (direct), magnetic or radiative excitation of absorber ...

Molecular mechanisms of thermosensation

Folia Pharmacologica Japonica, 2004
We feel a wide range of temperatures spanning from cold to heat. Within this range, temperatures over about 43 degrees C and below about 15 degrees C evoke not only a thermal sensation, but also a feeling of pain. In mammals, six thermosensitive ion channels have been reported, all of which belong to the TRP (transient receptor potential) super family.

Unlocking the therapeutic potential of TRPV3: Insights into thermosensation, channel modulation, and skin homeostasis involving TRPV3

BioEssays, Volume 46, Issue 7, July 2024.
TRPV3, a warmth sensor, plays a role in maintaining skin homeostasis. The discovery of membrane protein TMEM79 modulation on TRPV3 in keratinocytes underscores their role in warmth sensation. Thus, comprehensive understanding of TRPV3 in physiology and pathology yields insight into skin function.

Heat Resistant Organic Dyes for High Temperature Luminescent Temperature Sensing

Advanced Sensor Research, Volume 3, Issue 4, April 2024.
A blue organic emitter is developed with high heat resistance, due to an offset between thermally populating to high‐lying emissive states and facilitated nonradiative decay. By hybridizing with a yellow ESIPT fluorophore, a sensitive ratiometric high‐temperature film thermometer is demonstrated, which enables large‐area thermal mapping and multiple ...

Measurement and Control of Single Nitrogen-Vacancy Center Spins above 600 K

, 2012
We study the spin and orbital dynamics of single nitrogen-vacancy (NV) centers in diamond between room temperature and 700 K. We find that the ability to optically address and coherently control single spins above room temperature is limited by ...

Cerulenin inhibits unsaturated fatty acids synthesis in Bacillus subtilis by modifying the input signal of DesK thermosensor [PDF]

, 2014
Bacillus subtilis responds to a sudden decrease in temperature by transiently inducing the expression of the des gene encoding for a lipid desaturase, D5-Des, which introduces a double bond into the acyl chain of preexisting membrane phospholipids.

Thermochromic Afterglow from Benzene‐1,4‐Diboronic Acid‐Doped Co‐crystals

Chemistry – A European Journal, Volume 30, Issue 14, March 7, 2024.
The afterglow color of benzene‐1,4‐diboronic acid (BDBA)‐doped co‐crystals with trimethylolpropane (TMP) varied from bluish to greenish color towards an increase of temperature from −132 to 40 °C. Based on the photophysical properties of co‐crystals and TD‐DFT calculations, the molecular distortions at the singlet excited states enhanced the spin‐orbit
