Bidirectional Control of Emotional Behaviors by Excitatory and Inhibitory Neurons in the Orbitofrontal Cortex.

The orbitofrontal cortex (OFC) plays a crucial role in mood disorders; however, its specific role in the emotional behaviors of mice remains unclear. This study investigates the bidirectional control of emotional behaviors using population calcium dynamics and optogenetic manipulation of OFC neurons. Fiber photometry of OFC neurons revealed that OFC excitatory neurons consistently responded to the onset and offset of aversive conditions, showing decreased activation in response to anxiogenic and stressful stimuli, including tail suspension, restraint stress, and exposure to the center of the open field.

The genetically programmed rhythmic alteration of diurnal gene expression in the aged leaves.

Conserved pattern-based classification of human odorant receptor multigene family.

Conserved protein-coding sequences are critical for maintaining protein function across species. Odorant receptors (ORs), a large poorly understood multigene family responsible for odor detection, lack comprehensive classification methods that reflect their functional diversity. In this study, we propose a new approach called conserved motif-based classification (CMC) for classifying ORs based on amino acid sequence similarities within conserved motifs.

Niclosamide attenuates calcification in human heart valvular interstitial cells through inhibition of the AMPK/mTOR signaling pathway.

Calcific aortic valve disease (CAVD) is a considerable health burden with a lack of effective therapeutic options. There is an urgent need to develop interventions that inhibit the osteogenic transformation of valvular interstitial cells (VICs) and delay the calcification process. Niclosamide, an FDA-approved anti-helminthic drug, has emerged as a promising candidate that demonstrates a negative regulatory effect on porcine VICs calcification.

Tailoring-Orientated Deposition of LiS for Extreme Fast-Charging Lithium-Sulfur Batteries.

Precipitation/dissolution of insulating LiS has long been recognized as the rate-determining step in lithium-sulfur (Li-S) batteries, which dramatically undermines sulfur utilization at elevated charging rates.
