Self‐Trapped Hole Migration and Defect‐Mediated Thermal Quenching of Luminescence in α‐ and β‐Ga2O3
Advanced Functional Materials, EarlyView.Temperature‐dependent photoluminescence and first‐principles calculations reveal self‐trapped hole migration as the microscopic origin of thermal quenching in α‐ and β‐Ga2O3. The low migration barrier in α‐Ga2O3 enables defect trapping and enhances blue luminescence, while the higher barrier in β‐Ga2O3 preserves ultraviolet emission at elevated ...

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization
Advanced Functional Materials, EarlyView.Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples
Advanced Functional Materials, EarlyView.Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Trazodone inhibits T-type calcium channels
Neuropharmacology, 2007Trazodone is one of the most commonly prescribed medicines for treating depression and insomnia. However, the pharmacological mechanism of action underlying trazodone's unique effects is unclear. Despite its nanomolar affinity for 5HT(2A) receptors, histamine(1) receptors and alpha(1) adrenoceptors the drug is given at high doses to achieve clinical ...

Molecular Biology of T-Type Calcium Channels
CNS & Neurological Disorders - Drug Targets, 2006This review summarizes recent progress on the molecular biology of low voltage-gated, T-type, calcium channels. The genes encoding these channels were identified by molecular cloning of cDNAs that were similar in sequence to the alpha1 subunit of high voltage-activated Ca2+ channels.

T-type calcium channels and tumor proliferation
Cell Calcium, 2006The role of T-type Ca2+ channels in proliferation of tumor cells is reviewed. Intracellular Ca2+ is important in controlling proliferation as evidenced by pulses, or oscillations, of intracellular Ca2+ which occur in a cell cycle-dependent manner in many tumor cells.

Aldosterone regulation of T-type calcium channels
The Journal of Steroid Biochemistry and Molecular Biology, 2003Voltage-operated calcium channels play a crucial role in signal transduction in many excitable and non-excitable cell types. While a rapid modulation of their activity by hormone-activated kinases and/or G proteins has been recognized for a long time, a sustained control of their expression level has been only recently demonstrated.
