Wines' Volatile and Non-Volatile Characterization
Phenolic and volatile compounds have been the most common variables studied in wines due to their importance in chemical, physical and sensory properties. Phenolic compounds come from grapes and oak wood of the barrels where wines are aged and affect color and gustatory properties of wines, such as astringency, bitterness and structure.

Oxidative Stress in NAFLD
Oxidative stress is defined as an imbalance between the cellular levels of antioxidants and that of pro-oxidants, including ROS and reactive nitrogen species, which causes cellular damage and, in most cases, cell death. Non-alcoholic fatty liver disease (NAFLD) is often the hepatic expression of metabolic syndrome and its comorbidities that comprise, among others, obesity and insulin-resistance. At the molecular level, several models have been proposed for the pathogenesis of NAFLD. Most importantly, oxidative stress and mitochondrialdamage have been reported to be causative in NAFLD initiation and progression.

Endophytic Bacterial in Rice Plant
Endophytic bacterial communities are beneficial communities for host plants that exist inside the surfaces of plant tissues, and their application improves plant growth. They benefit directly from the host plant by enhancing the nutrient amount of the plant’s intake and influencing the phytohormones, which are responsible for growth promotion and stress. Endophytic bacteria play an important role in plant-growth promotion (PGP) by regulating the indirect mechanism targeting pest and pathogens through hydrolytic enzymes, antibiotics, biocontrol potential, and nutrient restriction for pathogens.

PCSK9 Inhibitors
Proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors are a novel group of hypolipidemic drugs that are recommended particularly for high-risk hypercholesterolemia patients, including those with primary hypercholesterolemia (PH), where lifelong exposure to high low-density lipoprotein (LDL) cholesterol levels results in an elevated risk of atherosclerosis at an early age. The onset and progression of atherosclerosis is significantly influenced by activated platelets. Oxidized LDL influences platelet activation by interacting with their surface receptors and remodeling the composition of their cell membrane. This results in platelet aggregation, endothelial cell activation, promotion of inflammation and oxidative stress, and acceleration of lipid accumulation in atherosclerotic plaques. PCSK9 inhibitors reduce platelet activation by both significantly lowering LDL levels and reducing the LDL receptor-mediated activation of platelets by PCSK9. They also work synergistically with other hypolipidemic and antithrombotic drugs, including statins, ezetimibe, acetylsalicylic acid, clopidogrel, and ticagrelor, which enhances their antiplatelet and LDL-lowering effects.

List of Amphibians
List of amphibians organizes the class of amphibian by family and subfamilies and mentions the number of species in each of them. The list below largely follows Darrel Frost's Amphibian Species of the World (ASW), Version 5.5 (31 January 2011). Another classification, which largely follows Frost, but deviates from it in part is the one of AmphibiaWeb, by the University of California, Berkeley. The major differences between these two classifications are:

Yao Syndrome
Yao syndrome (formerly called NOD2-associated autoinflammatory disease) is a disorder involving episodes of fever and abnormal inflammation affecting many parts of the body, particularly the skin, joints, and gastrointestinal system.

Microbial Enzyme Applied to Plastic Depolymerization
The accumulation of synthetic plastic waste in the environment has become a global concern. Microbial enzymes (purified or as whole-cell biocatalysts) represent emerging biotechnological tools for waste circularity; they can depolymerize materials into reusable building blocks, but their contribution must be considered within the context of present waste management practices.

Advances of Microneedles in Biomedical Applications
A microneedle (MN) is a painless and minimally invasive drug delivery device initially developed in 1976. As microneedle technology evolves, microneedles with different shapes (cone and pyramid) and forms (solid, drug-coated, hollow, dissolvable and hydrogel-based microneedles) have been developed.

Chemical Speciation of Iodine and Practical Applications
Iodine is one of the 30 essential elements for life, and its chemical speciation defines its biological activities. Both inorganic and organic chemical species have crucial roles in the biology of most living organisms. The most relevant inorganic species are iodate (IO3−) and iodide (I−), as the major sources of iodine for living beings, together with molecular iodine (I2) and hypoiodous acid (HIO) as the most reactive performing catalytic activities. Conversely, Thyroid Hormones (THs) are the master regulators of the metabolism of vertebrates and the representative organic species. Mainly inorganic species are exploited in the health science industry to produce disinfectants, supplements, medicines, and X-ray contrast media.

Nikolaas Tinbergen
Nikolaas "Niko" Tinbergen FRS (/ˈtɪnbɜːrɡən/; Dutch: [ˈnikoːlaːs ˈnikoː ˈtɪnbɛrɣən]; 15 April 1907 – 21 December 1988) was a Dutch biologist and ornithologist who shared the 1973 Nobel Prize in Physiology or Medicine with Karl von Frisch and Konrad Lorenz for their discoveries concerning organization and elicitation of individual and social behavior patterns in animals. He is regarded as one of the founders of modern ethology, the study of animal behavior. In 1951, he published The Study of Instinct, an influential book on animal behaviour. In the 1960s, he collaborated with filmmaker Hugh Falkus on a series of wildlife films, including The Riddle of the Rook (1972) and Signals for Survival (1969), which won the Italia prize in that year and the American blue ribbon in 1971.
