Enhanced Dielectric Properties of a Poly(dimethyl siloxane) Bimodal Network Percolative Composite with MXene.

Excellent comprehensive dielectric properties (including dielectric constant and loss) are essential for electromechanical transducers. This work introduced a bimodal network composite with poly(dimethyl siloxane) (PDMS) and delaminated TiCT sheets (-TiCT) modified with hyperbranched polysiloxane (HPSi) (referred to as HPSi--TiCT). Before the final cross-linking, HPSi--TiCT, trapped with short-chain PDMS (C-PDMS) and long-chain PDMS (C-PDMS), was pre-reacted, which formed a distinct bimodal network structure.

[Effect of fasudil of on rat cardiomyocytes acutely exposed to omethoate].

Objective: To investigate the effect of fasudil on in vitro cultured cardiomyocytes (CMs) exposed to omethoate and its possible mechanism.

Methods: Cardiomyocytes were isolated from male SD rats and were then cultured in DMEM conventionally. The CMs were divided into different groups based on the doses of omethoate and fasudil in culture media.

[Effect of methylene blue on traumatic shock in rabbits].

Objective: To observe the effect of methylene blue (MB) on the changes in plasma nitric oxide (NO), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and visceral pathologic changes in rabbits with traumatic shock.

Methods: Eighteen rabbits were randomly assigned into 3 groups (n=6): sham operation group, traumatic shock with normal saline (NS) resuscitation group (NS group), and traumatic shock with MB resuscitation group (MB group). In NS group and MB group, hemodynamics was monitored, and plasma contents of NO, TNF-alpha and IL-6 were determined before shock, after shock, after resuscitation, and 0.
