The Natural Antherea pernyi Sericin Protein Suppresses Gastric Cancer Formation by Inhibiting Cell Proliferation and Inducing Cell Apoptosis
Published on 2025-02-22 by Qiong-Qiong Wei, Yu Xiao, Qiao Wu, Cai Jing, Zhan-Qi Dong, Peng Chen, Min-Hui Pan @MDPI
Abstract: Sericin, a natural macromolecular protein and the main component of silkworm cocoons, exhibits biocompatibility, excellent mechanical properties, and biodegradability. Previous research has confirmed that the sericin protein possesses anticancer properties. Gastric cancer (GC) poses a serious hazard to human health, with a low rate of early diagnosis and a poor prognosis. Investigating the safety and effectiveness of drugs for their used in treatment is imperative. In this study, we confirmed th[...]
Our summary: The study confirms that Antherea pernyi sericin suppresses gastric cancer formation by inhibiting cell proliferation and inducing cell apoptosis, showing minimal toxicity and adverse side effects. It also demonstrates the potential of sericin as a natural macromolecular polypeptide drug for tumor treatment.

ZnO-Embedded Carboxymethyl Cellulose Bioplastic Film Synthesized from Sugarcane Bagasse for Packaging Applications
Published on 2025-02-22 by Anand Vyas, Sun-pui Ng, Tao Fu, Ifrah Anum @MDPI
Abstract: This research explores the synthesis of carboxymethyl cellulose (CMC) for the development of a cost-effective bioplastic film that can serve as a sustainable alternative to synthetic plastic. Replacing plastic packaging with CMC-based films offers a solution for mitigating environmental pollution, although the inherent hydrophilicity and low mechanical strength of CMC present significant challenges. To address these limitations, zinc oxide nanoparticles (ZnO NPs) were employed as a biocompatible[...]
Our summary: Synthesis of CMC-based bioplastic film with ZnO NPs for sustainable packaging, improved mechanical properties and thermal stability, enhanced water-related properties, high biodegradability.

Effects of Granulated Cork with Bark on the Microstructure and Resistance to Extreme Environmental Conditions of Concrete for Non-Structural Precast Elements
Published on 2025-02-21 by María Concepción Pacheco Menor, María José Arévalo Caballero, Antonio Macías García, Pedro Serna Ros @MDPI
Abstract: The building sector is responsible for major environmental impacts. Utilising bio-based raw materials, such as bio-aggregates, in concrete production could address to this environmental challenge. While the physical and mechanical properties of various bio-based concretes have been explored, research on their microstructure and resistance to extreme conditions is limited. Cork is a light, renewable and biodegradable material. Cork industries produce a considerable number of solid wastes, among t[...]

Stackable planar adsorptive devices
Patent published on the 2025-02-19 in EP under Ref EP4509829 by SPF TECH LLC [US] (De Los Reyes Gaston [us])
Abstract: Adsorptive bed devices include a scaffold in housing having a stress absorbing rigid structure and open cells filled with adsorptive beads. The scaffold restricts movement of the plurality of adsorptive beads, absorbs stress induced by a hydraulic pressure gradient along a direction of liquid flow and transfers a portion of the induced compressive stress to the housing. In one embodiment the adsorptive bed is packed into a chromatography column, and in another embodiment the adsorptive bed is se[...]
