Metabolite profiling and 'dryness'-like effect analysis of 'Chenpi' plant tea (Citri Reticulatae Pericarpium peel) with and without steaming peocessing.

Citri Reticulatae Pericarpium peel ('Chenpi' tea) is a popular food-medicine functional tea, which mainly existing unsteamed (CRP) and steamed (SCRP) products. In this study, a combination of electronic nose and GC-MS analysis showed that aged SCRP had a more intense aroma, which was attributed to the significant reduction or disappearance of components representing refreshing aroma, such as β-Myrcene and d-Limonene, while some components with thick odors like Valencene were newly formed. For the 'dryness'-like effect, the weaker effect of SCRP relative to CRP was initially confirmed in rats, as characterized by water intake, submandibular gland index, and hemorheology, consistenting with the expression trend of aquaporin (AQP) 2, 3 and 5 mRNA.

Dispersive terahertz metasurface fed by a horn antenna for highly oriented 2D beam steering.

Highly oriented beam steering will enhance power density and field of view (FOV) in terahertz wireless links. Metasurface can be constructed by deliberate arrangement of subwavelength meta-cells to manipulate the wavefront. This paper explores a dispersive metasurface with a specific phase gradient patterned in a 2-inch aperture, allowing for collimated beamforming and two-dimensional (2D) beam steering by a combination of frequency tuning and metasurface rotation.

Identification of potential anti-inflammatory components in Moutan Cortex by bio-affinity ultrafiltration coupled with ultra-performance liquid chromatography mass spectrometry.

Moutan Cortex (MC) has been used in treating inflammation-associated diseases and conditions in China and other Southeast Asian countries. However, the active components of its anti-inflammatory effect are still unclear. The study aimed to screen and identify potential cyclooxygenase-2 (COX-2) inhibitors in MC extract.
