Prim-O-glucosylcimifugin alleviates influenza virus-induced pneumonia in mice by inhibiting the TGF-β1/PI3KCD/MSK2/RELA signalling pathway.

Prim-O-glucosylcimifugin (POG) is a chromone derived primarily from Saposhnikovia divaricata (Turcz) Schischk and Cimicifuga simplex. Previous research has shown that POG possesses antibacterial, anticancer, anti-inflammatory, antioxidant, anticonvulsant, antipyretic, and analgesic properties. However, the specific impact of POG on influenza-virus-induced pneumonia is not well understood.

Recent Progress of Imprinted Polymer Photonic Waveguide Devices and Applications.

Polymers are promising materials for fabricating photonic integrated waveguide devices. Versatile functional devices can be manufactured using a simple process, with low cost and potential mass-manufacturing. This paper reviews the recent progress of polymer photonic integrated devices fabricated using the UV imprinting technique.

Polymer-Based Device Fabrication and Applications Using Direct Laser Writing Technology.

Polymer materials exhibit unique properties in the fabrication of optical waveguide devices, electromagnetic devices, and bio-devices. Direct laser writing (DLW) technology is widely used for micro-structure fabrication due to its high processing precision, low cost, and no need for mask exposure. This paper reviews the latest research progresses of polymer-based micro/nano-devices fabricated using the DLW technique as well as their applications.

Expression of surfactant protein-A in exhaled breath condensate of patients with chronic obstructive pulmonary disease.

Pulmonary surfactant protein A (SP-A) has been associated with host defense in the lung, and contributes to the pathogenesis of chronic obstructive pulmonary disease (COPD). The present study aimed to determine a non‑invasive method of measurement of SP‑A, and further examine the expression levels of SP‑A in patients with COPD. SP‑A was detected in the exhaled breath condensate (EBC) obtained from patients with COPD and from non‑COPD subjects.
