Cardiomyocytes Contractile Activity on Poly(vinyl-alcohol)/Bioglass Electrospun Scaffolds
Tissue scaffolds are generally used as three-dimensional structural supports destined to mimic the morphological structure and function in regeneration processes. Still, beyond this, they are expected to perform the physiological functions for which each tissue or organ is intended. In the case of cardiac tissue, it brings oxygen through the blood to each part of the body through the contraction of the cardiac muscle cells (cardiomyocytes). This contraction is neurologically stimulated through a voltage and calcium-dependent process denominated excitation-contraction coupling, which is mediated by several factors. In this sense, the composition of the scaffold becomes relevant.

Carica papaya Leaf Extract
Carica papaya (papaya) leaf extract has been used for a long time in a traditional medicine to treat fever in some infectious diseases such as dengue, malaria, and chikungunya. The development of science and technology has subsequently made it possible to provide evidence that this plant is not only beneficial as an informal medication, but also that it has scientifically proven pharmacological and toxicological activities, which have led to its formal usage in professional health care systems.

Carotenoid-Loaded Nanocarriers for Alzheimer’s Disease Therapy
Natural bioactive compounds have emerged as a strategy for Alzheimer’s disease treatment. Carotenoids, including astaxanthin, lycopene, lutein, fucoxanthin, crocin and others are natural pigments and antioxidants, and can be used to treat a variety of diseases, including Alzheimer’s disease. However, carotenoids, as oil-soluble substances with additional unsaturated groups, suffer from low solubility, poor stability and poor bioavailability. Therefore, the preparation of various nano-drug delivery systems from carotenoids is a current measure to achieve efficient application of carotenoids. Different carotenoid delivery systems can improve the solubility, stability, permeability and bioavailability of carotenoids to a certain extent to achieve Alzheimer’s disease efficacy.

Carrageenan-Based Hard Capsules: Review
Carrageenan is used as a gelling agent in products, such as frozen foods, jellies and yogurt. Commercially, carrageenan has been produced in six different types based on their structures. Among the six polymers, κ-carrageenan is the most produced due to its high gelling ability caused by the C4 conformation on the 3,6-anhydro-D-galactopyranosyl that forms a helix-like structure. The formation of the helix structure is supported by the enormous number of –OH groups that form many hydrogen bonds.

Cartilage Lubrication in Osteoarthritis
The remarkable lubrication properties of normal articular cartilage play an essential role in daily life, providing almost frictionless movements of joints. Alterations of cartilage surface or degradation of biomacromolecules within synovial fluid increase the wear and tear of the cartilage and hence determining the onset of the most common joint disease, osteoarthritis (OA).

Caspase-1 Inhibition
The inflammatory protease caspase-1 is associated with the release of cytokines. An excessive number of cytokines (a “cytokine storm”) is a dangerous consequence of COVID-19 infection and has been indicated as being among the causes of death by COVID-19. The anti-inflammatory drug colchicine (which is reported in the literature to be a caspase-1 inhibitor) and the corticosteroid drugs, dexamethasone and methylprednisolone, are among the most effective active compounds for COVID-19 treatment.

Catalyst Design via Colloidal Synthesis
Supported nanoparticles are commonly applied in heterogeneous catalysis. The catalytic performance of these solid catalysts is, for a given support, dependent on the nanoparticle size, shape, and composition, thus necessitating synthesis techniques that allow for preparing these materials with fine control over those properties. Such control can be exploited to deconvolute their effects on the catalyst’s performance, which is the basis for knowledge-driven catalyst design. In this regard, bottom-up synthesis procedures based on colloidal chemistry have proven successful in achieving the desired level of control for a variety of fundamental studies. This article aims to give an overview of recent progress made in this synthesis technique for the application of controlled catalytic materials in gas-phase catalysis. The focus goes to mono- and bimetallic materials, as well as to recent efforts in enhancing their performance by embedding colloidal templates in porous oxide phases.

Catalyst for Carbon Nanomaterials
Metal and metal oxide particles could be easily available in smaller amounts in almost all natural materials and could be used for CNTs synthesis. The growth of carbon nanomaterials employing natural materials as catalyst sources could be a significant solution towards lessening our current dependence on non-renewable and expensive catalyst sources for large-scale production.
