Journal of Periodontal Research, EarlyView.This split‐mouth randomized clinical trial showed that platelet‐rich fibrin impregnation of a volume‐stable collagen matrix did not improve clinical, esthetic, or patient‐reported outcomes compared with collagen matrix alone for multiple gingival recession treatment after 6 months. ABSTRACT Aim This split‐mouth randomized clinical trial aimed to assess

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha
New Phytologist, EarlyView.The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

A Microstrip Patch Antenna with Defected Ground Structure(DGS) for WiMAX and WLAN Applications
International Journal of Engineering and Advanced Technology, 2019 A rectangular microstrip patch antenna with defected ground structure with E-shaped and square shaped slot on the patch is proposed here. The proposed antenna design consists of H-shaped defect on the ground plane. The complete antenna system is constructed on 45.4mm X 45.4mm X 1.6mm, FR-4 substrate with dielectric constant of 4.4 and substrate height ...
