Growth of MoS Nanosheets on Brush-Shaped PI-ZnO Hybrid Nanofibers and Study of the Photocatalytic Performance.

The design and preparation of advanced hybrid nanofibers with controllable microstructures will be interesting because of their potential high-efficiency applications in the environmental and energy domains. In this paper, a simple and efficient strategy was developed for preparing hybrid nanofibers of zinc oxide-molybdenum disulfide (ZnO-MoS) grown on polyimide (PI) nanofibers by combining electrospinning, a high-pressure hydrothermal process, and in situ growth. Unlike simple composite nanoparticles, the structure is shown in PI-ZnO to be like the skeleton of a tree for the growth of MoS "leaves" as macro-materials with controlled microstructures.

Electronic spectroscopy and excited state mixing of OThF.

Electronic spectra for OThF have been recorded using fluorescence excitation and two-photon resonantly enhanced ionization techniques. Multiple vibronic bands were observed in the 340-460 nm range. Dispersed fluorescence spectra provided ground state vibrational constants and evidence of extensive vibronic state mixing at higher excitation energies.

Microfluidic platforms for monitoring cardiomyocyte electromechanical activity.

Cardiovascular diseases account for ~40% of global deaths annually. This situation has revealed the urgent need for the investigation and development of corresponding drugs for pathogenesis due to the complexity of research methods and detection techniques. An in vitro cardiomyocyte model is commonly used for cardiac drug screening and disease modeling since it can respond to microphysiological environmental variations through mechanoelectric feedback.

Comparative toxicity study of hyaluronic acid fillers crosslinked with 1,4-butanediol diglycidyl ether or poly (ethylene glycol) diglycidyl ether.

Dermal fillers comprising injectable hyaluronic acid (HA) are widely used for soft tissue augmentation, often using crosslinking agents such as 1,4-butanediol diglycidyl ether (BDDE) or poly (ethylene glycol) diglycidyl ether (PEGDE). Here, we assessed the physical properties, toxicity, and inflammatory reactions of HA fillers crosslinked with either BDDE (HA-BDDE filler) or PEGDE (HA-PEGDE filler) in in vitro and in vivo investigations. The HA-PEGDE filler exhibited higher G', tan δ, G*, and complex viscosity values compared to the HA-BDDE filler, while maintaining similar cohesivity.

The SGLT2 inhibitor remogliflozin induces vasodilation in the femoral artery of rabbits via activation of a Kv channel, the SERCA pump, and the cGMP signaling pathway.

This study explored the vasodilatory mechanisms of the sodium-glucose cotransporter-2 inhibitor remogliflozin using femoral arteries of rabbits. Remogliflozin dilated femoral arterial rings pre-contracted with phenylephrine in a concentration-dependent manner. Pretreatment with the Ca-sensitive K channel inhibitor (paxilline), the ATP-sensitive K channel inhibitor (glibenclamide), or the inwardly rectifying K channel inhibitor (Ba) did not alter the vasodilatory effect.
