LARP7 family proteins have conserved function in telomerase assembly

open access: yesNature Communications, 2018
The telomerase holoenzyme is minimally composed of the reverse transcriptase and the RNA template. Here the authors identify Lar7 as a member of the full complex that helps to stabilise it and protect telomerase RNA from degradation.

Date Palm Fiber-Reinforced Recycled Polymer Composites: Synthesis and Characterization

open access: yesAdvances in Polymer Technology, 2022
In this research study, Recycled Polymer (RP) composites are synthesized by using compression molding process, initial mixtures of RP and Date Palm Fibers (DPF) with four different lengths (e.g., 2.5, 5, 7.5, and 10 mm) and weight ratios (e.g., 5, 10, 15,
