Abstract: A novel Lactobacillus rhamnosus KBL2290 strain exhibits various activities such as improving intestinal flora, anti-inflammatory, and strengthening intestinal tight junctions. The strain may increase intestinal flora of Akkermansia genus, Lactobacillus genus, Ruminococcus genus or Prevotella genus, suppress an expression of interleukin 1-beta (IL-1B), interleukin 2 (IL-2), interleukin 4 (IL-4), interleukin 12p40 (IL-12p40), interleukin 13 (IL-13), or interleukin 17A (IL-17A), suppresses an expression of chemokine ligand 2 (CCL2) or chemokine ligand 1 (CXCL1), suppress an expression of cyclooxygenase 2 (Cox-2) or nitric oxide synthase (iNOS), promote an expression of interleukin 10 (IL-10) or transforming growth factor-β (TGF-β), and increase an expression of Zo-1 or Occludin. A pharmaceutical composition including the strain may prevent or treat inflammatory bowel disease.

Abstract: An exemplary embodiment attempts to provide a full transmission device for wide-angle mode conversion of elastic waves which can realize mode conversion of elastic waves with high energy efficiency over a wide range of angle of incidence by a single filter. A full transmission device for wide-angle mode conversion of elastic waves includes an incidence medium where elastic waves including longitudinal waves and transverse waves enter obliquely within a preset wide angle range, a transmission medium that transmits elastic waves when the elastic waves enter the transmission medium within the wide angle range through the incidence medium, and a filter that is formed so as to satisfy a wide-angle mode conversion full-transmission condition when the filter is interposed between the incidence medium and the transmission medium, such that elastic waves entering the incidence medium within the wide angle range are completely converted without being reflected so as to be transmitted to the transmission medium.
