Skeletal Muscle Myokines
The skeletal muscle is the largest organ in the body and secretes circulating factors, including myokines, which are involved in various cellular signaling processes. Skeletal muscle is vital for metabolism and physiology and plays a crucial role in insulin-mediated glucose disposal. Myokines have autocrine, paracrine, and endocrine functions, serving as critical regulators of myogenic differentiation, fiber-type switching, and maintaining muscle mass. Myokines have profound effects on energy metabolism and inflammation, contributing to the pathophysiology of type 2 diabetes (T2D) and other metabolic diseases. Myokines have been shown to increase insulin sensitivity, thereby improving glucose disposal and regulating glucose and lipid metabolism.

Phytoremediation
Phytoremediation is defined as the use of plant species as a means of purifying polluted soil, water, and air. The term derives from the Greek word phyto (“plant”) and the Latin word remedium (“to correct or remove an evil”). Phytoremediation is a more economically feasible and efficient remediation option than other techniques, such as washing, flushing, or solidification.

Coping Strategies and Prevention of Cyberbullying
Cyberbullying behaviours begin at primary school, so the actions taken by pre-teachers will play a key role in achieving the goals in the 2030 Agenda for Sustainable Development. More specifically, active coping strategies are essential in reducing victimisation. There is great importance of designing and implementing training programmes to prevent and/or reduce cyberbullying as part of student primary school teachers’ education. One promising way of achieving the Sustainable Development Goals in schools is to encourage pre-service teachers to use active strategies to intervene in cyberbullying and to abandon ineffective strategies in their future professional lives. It is important that pre-service teachers’ knowledge of effective coping strategies is enhanced and that any beliefs justifying cyberbullying are deconstructed.

Microplastic Removal and Degradation Techniques
Plastics are a kind of synthetic or semisynthetic polymer that are made up of long chains of carbon atoms, and they may also have oxygen, nitrogen, or sulfur atoms attached to them. The majority of plastics are produced by factories that use fossil fuels. Microplastics are small particles of fragments and microfibers of plastic that have a diameter of less than 5 mm. Because of the widespread usage of microbeads in a variety of goods as well as the fragmentation of plastics with increasing age, the quantity of microplastic released in the aquatic environment is alarming, and so effluent water needs to be treated in wastewater plants to remove the microplastics. Different biotic and abiotic approaches have been studied in different research over the years.

Fundamental Concepts of Hydrogels
Hydrogels are three-dimensional crosslinked porous networks and can be synthesized from natural polymers, synthetic polymers, polymerizable synthetic monomers, and combination of natural and synthetic polymers. Synthesis of hydrogels involves physical, chemical and hybrid bonding. The bonding is formed via different routes such as solution casting, solution mixing, bulk polymerization, free radical mechanism, radiation method, and interpenetrating network formation. The synthesized hydrogels have significant properties such as mechanical strength, flexibility, biocompatibility, biodegradability, swellability, and stimuli sensitivity. Furthermore, owing to the smart and aqueous medium, robust mechanical strength, adhesiveness, stretchability, strain sensitivity, and self-healability, hydrogels can be potentially used in biomedical, electrochemical, sensors, contact lens, and soft robotic applications.

Adult Play with Character Toys
Character toys are toys identifiable by name, personality, and visual traits. They represent specific characters derived from or associated with popular culture. This entry explores adult engagement with character toys, or toy play, through a multidisciplinary lens, emphasizing playability, materiality, affect, creativity, and sociocultural meaning. Drawing on earlier toy research on dolls, action figures, figurines, and soft toys—those with a face and assigned personality—it considers how adults collect, customize, create stories, and critique societal conditions through toys for personal enrichment, identity work, and community formation. The toy play of adults is framed as a legitimate and complex form of self-expression and cultural participation that intersects with object play, creative fandoms, and political resistance.

Pashupata Shaivism
Pashupata Shaivism (Pāśupata, Sanskrit: पाशुपत) is the oldest of the major Shaivite Hindu schools. The philosophy of the Pashupata sect was systematized by Lakulīśa also called Nakulīśa) in the 2nd century A.D. The main texts of the school are Pāśupatasūtra with Kauṇḍinya's Pañcārthabhāṣya, and Gaṇakārikā with Bhāsarvajña's Ratnaṭīkā. Both texts were discovered only in the twentieth century. Prior to that, the major source of information on this sect was a chapter devoted to it in Vidyāraṇya's Sarvadarśanasaṅgraha.

Sulfonamide
Sulfonamide is a functional group (a part of a molecule) that is the basis of several groups of drugs, which are called sulphonamides, sulfa drugs or sulpha drugs. The original antibacterial sulfonamides are synthetic (nonantibiotic) antimicrobial agents that contain the sulfonamide group. Some sulfonamides are also devoid of antibacterial activity, e.g., the anticonvulsant sultiame. The sulfonylureas and thiazide diuretics are newer drug groups based upon the antibacterial sulfonamides. Allergies to sulfonamides are common. The overall incidence of adverse drug reactions to sulfa antibiotics is approximately 3%, close to penicillin; hence medications containing sulfonamides are prescribed carefully. Sulfonamide drugs were the first broadly effective antibacterials to be used systemically, and paved the way for the antibiotic revolution in medicine.

Technologies for Detecting Oxygen Vacancies
A perovskite catalyst combined with various advanced oxidation processes (AOPs) to treat organic wastewater attracted extensive attention. The physical and chemical catalytic properties of perovskite were largely related to oxygen vacancies (OVs). OVs were able to alter the chemical, physical, and electronic properties of materials, so they became one of the most important research subjects. It was usually necessary to observe and analyze the phenomenon caused by OVs; however, due to their low concentration and short existence time, OVs were normally not visible to the naked eye. The relative concentration of OVs ranged from PPM to tens of atomic percent, a condition that was difficult to find a fitting experimental plan to characterize and distinguish OVs.

Industrial Hemp
Hemp is a type of Cannabis sativa plant and has multiple applications in food, construction, pharmaceuticals, and materials. Hemp was used in fabrics, twine, and paper products in the 1800s and 1900s; however, its production and applications were regulated with the Marijuana Tax Act in 1937 and the Controlled Substances Act in 1970 by the US Congress. In the 2014 Farm Bill, the US Congress defined industrial hemp depending on the level of THC (less than 0.3% THC on a dry weight basis) and allowed its agricultural pilot program by research institution and department of agriculture if the state laws allow.
