"City-states" Natural Recordings by Native Speakers
A city-state is a small independent republic or government that is centered in a single city, typically with a defined territory and a degree of sovereignty. City-states are often found in urban areas and are characterized by a strong sense of civic identity and social cohesion. They may be independent and self-governing, or may be part of a larger state or federation. Examples of city-states include Singapore, Monaco, and San Marino.
Citrullination is a post-translational modification of proteins in which an amino acid called citrulline is inserted into the protein in place of the amino acid arginine. This process is often referred to as a "deimination" reaction. Citrullination is a key step in the formation of citrullinated proteins, which have been implicated in various physiological and pathological processes, including autoimmune diseases such as rheumatoid arthritis and cancer.
Citrullinemia is a rare genetic disorder that affects the metabolism of the amino acid citrulline. Individuals with citrullinemia have a deficiency in the enzyme arginase, which is necessary for the breakdown of citrulline into ornithine and urea. As a result, the body accumulates excess citrulline, which can lead to a range of symptoms including intellectual disability, seizures, and vomiting, as well as liver problems and developmental delays. Citrullinemia can be diagnosed through blood tests and genetic analysis, and treatment typically involves a special diet and medication to manage symptoms.
Citruses refers to a group of juicy, sour-tasting fruits that grow on citrus trees, such as oranges, lemons, limes, grapefruits, and tangerines.

A cityscape refers to a visual representation or depiction of an urban area's landscape, typically featuring buildings, streets, and other man-made structures. It can be a two-dimensional image, such as a painting, photograph, or architectural rendering, or a three-dimensional representation, like a diorama or scale model. Cityscapes often aim to capture the character and essence of a place, conveying the urban experience and the relationship between architecture, nature, and human activity.
