Tumor Necrosis Factor -Related Apoptosis-Inducing Ligand Signaling Pathways
The tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a type II transmembrane protein that undergoes proteolytic cleavage to produce an extracellular ligand. TRAIL can bind to decoy receptor 1 (DcR1) which lacks a death domain (DD) altogether, and DcR2 which has a truncated DD. These decoy receptors are unable to induce DISC (death-inducing signaling complex) formation and act as negative regulators of the apoptotic signaling by competitively binding TRAIL. The canonical TRAIL-induced apoptotic signaling pathway is an example of apoptosis mediated through the extrinsic death pathway, which entails activation of cell-surface receptors by a ligand to induce activation of downstream caspases.

Applications of Chitosan
Public health, production and preservation of food, development of environmentally friendly (cosmeto-)textiles and plastics, synthesis processes using green technology, and improvement of water quality, among other domains, can be controlled with the help of chitosan. This aminopolysaccharide is recognized as safe and produced from an abundant and renewable source (chitin). Chitosan exhibits advantageous properties, such as biocompatibility, biodegradability, antimicrobial effect, mucoadhesive properties, film-forming capacity, elicitor of plant defenses, coagulant-flocculant ability, synergistic effect and adjuvant along with other substances and materials. In part, its versatility is attributed to the presence of ionizable and reactive primary amino groups that provide strong chemical interactions with small inorganic and organic substances, macromolecules, ions, and cell membranes/walls. Hence, chitosan has been used either to create new materials or to modify the properties of conventional materials applied on an industrial scale.

Self-Assembling Peptide
Self-assembling peptides are biomedical materials with unique structures that are formed in response to various environmental conditions. Governed by their physicochemical characteristics, the peptides can form a variety of structures with greater reactivity than conventional non-biological materials. The structural divergence of self-assembling peptides allows for various functional possibilities; when assembled, they can be used as scaffolds for cell and tissue regeneration, and vehicles for drug delivery, conferring controlled release, stability, and targeting, and avoiding side effects of drugs. These peptides can also be used as drugs themselves.  We describe the self-assembling peptide sequences and resultant nanostructures used for disease treatments.

Milk Thistle Seed and Hempseed
In accordance with Commission Regulation (EC) No 726/2004, the use of antibiotics as stimulators of animal growth and performance has been banned in all European Union countries since 2006 (due to the elimination of antibiotic residues from the human food chain). Due to this ban, many scientists are studying alternative approaches to the use of various biologically active substances with a growth-promoting e ect. A promising direction is the use of alternative feeds containing bioactive compounds or mixtures of natural origin, or the use of phytoadditives or plant extracts, probiotics, prebiotics, symbiotics or oilseed by-products, such as hempseed cakes and milk thistle seed cakes in animal nutrition.

Steam Reforming of Glycerol
In the last decades, environmental crises and increasing energy demand have motivated researchers to investigate the practical techniques for the production of clean fuels through renewable energy resources. It is essential to develop technologies to utilize glycerol as a byproduct derived from biodiesel. Glycerol is known as a sustainable and clean source of energy, which can be an alternative resource for the production of value-added chemicals and hydrogen. The hydrogen production via steam reforming (SR) of glycerol using Ni-based catalysts is one of the promising approaches for the entry of the hydrogen economy. The purpose of this review paper is to highlight the recent trends in hydrogen production over Ni-based catalysts using the SR of glycerol. The intrinsic ability of Ni to disperse easily over variable supports makes it a more viable active phase for the SR catalysts. The optimal reaction conditions have been indicated as 650–900 °C, 1 bar, and 15 wt% Ni in catalysts for high glycerol conversion. In this review paper, the effects of various supports, different promoters (K, Ca, Sr, Ce, La, Cr, Fe), and process conditions on the catalytic performance have been summarized and discussed to provide a better comparison for the future works. It was found that Ce, Mg, and La have a significant effect on catalytic performance as promoters. Moreover, SR of glycerol over hydrotalcite and perovskite-based catalysts have been reviewed as they suggest high catalytic performance in SR of glycerol with improved thermal stability and coke resistance. More specifically, the Ni/LaNi0.9Cu0.1O3 synthesized using perovskite-type supports has shown high glycerol conversion and sufficient hydrogen selectivity at low temperatures. On the other hand, hydrotalcite-like catalysts have shown higher catalytic stability due to high thermal stability and low coke formation. It is vital to notice that the primary concern is developing a high-performance catalyst to utilize crude glycerol efficiently.

Minor Intron Splicing
Pre-mRNA splicing is an essential step in gene expression and is catalyzed by two machineries in eukaryotes: the major (U2 type) and minor (U12 type) spliceosomes. While the majority of introns in humans are U2 type, less than 0.4% are U12 type, also known as minor introns (mi-INTs), and require a specialized spliceosome composed of U11, U12, U4atac, U5, and U6atac snRNPs. The high evolutionary conservation and apparent splicing inefficiency of U12 introns have set them apart from their major counterparts and led to speculations on the purpose for their existence.

Copper-Catalyzed Synthesis of Coumarins
Coumarin (2H-chromen-2-one) derivatives have important uses in medicinal and synthetic chemistry, for example, as fluorescent probes. These properties have prompted chemists to develop efficient synthetic methods to synthesize the coumarin core and/or to functionalize it. In this context, many metal-catalyzed syntheses of coumarins have been introduced; among them, copper-catalyzed reactions appear to be very promising owing to the non-toxicity and cheapness of copper complexes.

Bioenergy
Bioenergy is energy made from biomass or biofuel. Biomass is any organic material which has absorbed sunlight and stored it in the form of chemical energy. Examples are wood, energy crops and waste from forests, yards, or farms. Since biomass technically can be used as a fuel directly (e.g. wood logs), some people use the terms biomass and biofuel interchangeably. More often than not, the word biomass simply denotes the biological raw material the fuel is made of. The word biofuel is usually reserved for liquid or gaseous fuels, used for transportation. The U.S. Energy Information Administration (EIA) follows this naming practice. The IPCC (Intergovernmental Panel on Climate Change) defines bioenergy as a renewable form of energy. Researchers have disputed that the use of forest biomass for energy is carbon neutral.

Long Non-coding RNAs
Long noncoding RNAs (lncRNAs) constitute important group of RNA molecules with various biological activities. Despite significant progress in the understanding of lncRNAs, pivotal functions of this class of molecules are emerging. Among these, role in DNA damage response (DDR) seems to be fundamental. Various lncRNAs were found to modulate DNA repair on different levels: through TP53 activity modulation at transcriptional and translational level, through recruitment of chromatin remodelers that modulate the access of DNA repair proteins to the site of damage, and by working as scaffolds and mediators for DNA repair proteins, and acting as sponges for various DNA-damage-associated miRNAs. Considering that, lncRNAs involvement in DDR constitute interesting field of research with numerous future applications, such as development of new targeted anticancer therapies.

Cobalt–Chromium Dental Alloys
Co–Cr dental alloys consist of Co, Cr and also other metals (e.g., gallium, iron, molybdenum, nickel, ruthenium, tungsten). Since the 1990s, regulations have emerged to protect European patients and also monitor recent scientific knowledge. The use of metals and, therefore, dental alloys has been highly regulated by directives and regulations. Europe has, therefore, developed a regulatory package to protect all players involved in alloys, whether they are metal producers, manufacturers of alloys and medical devices, healthcare professionals and patients. Objective information is provided about Co–Cr dental alloys, with regard to both the latest toxicological data and regulatory developments from 2020–2025. The release of metal ions and the problem of wear particles are also discussed. With the recent change of regulatory status of Co, it is necessary to know the many repercussions (economic, technical etc.) of their use precisely in order to then allow actors to modify their daily work. The legislative changes also bring the need to propose new alternatives to Co-Cr dental alloys.

Antibiotics in Avian Species
Bacterial infections are commonly diagnosed and treated with antibiotics in the avian species. Infected birds can spread zoonotic diseases such as influenza, psittacosis, pasteurellosis, and campylobacteriosis to humans, especially if they are in close contact with them, such as pet-owner settings, zoos, or pet shops. The elimination of bacterial infections in birds is therefore important for both human and avian health.
