Nephrology is a medical specialty that focuses on the study of kidney physiology and diseases. This branch of medicine encompasses a wide range of conditions affecting renal function, including…
Life sciencesNest
A nest is a structure built by animals to hold their eggs or young. These constructions can vary significantly in shape, size, and material, depending on the species that creates them. Nests are…
Life sciencesNesting Site
A nesting site is a specific location where animals build their nests, which is a crucial aspect of their life cycle. These sites can vary significantly depending on the species, environment, and…
Life sciencesNettle
Nettle is a flowering plant belonging to the genus Urtica, known for its stinging hairs that can cause skin irritation upon contact. These plants are commonly found in temperate and tropical regions…
Life sciencesNeurocognitive Disorders
Neurocognitive disorders are conditions that impact an individual's cognitive function, resulting from neurological problems affecting the brain. These conditions can manifest in various forms…
Life sciencesNeuroinformatics
Neuroinformatics is the application of computer science to the field of neuroscience, integrating computational tools for the analysis and modeling of neurobiological data. This discipline aims to…
Life sciencesNeuropathy
Neuropathy is a disorder resulting from damage to the peripheral nerves, which are the nerves connecting the central nervous system to the rest of the body. This damage can lead to a variety of…
Life sciencesNeuroprosthetics
Neuroprosthetics are devices designed to replace or enhance the function of the nervous system, allowing for the restoration of motor or sensory capabilities in individuals who have suffered injuries…
Life sciencesNeutrophil
Neutrophils are a type of white blood cell, specifically a type of leukocyte, that plays a crucial role in the immune system of the human body. They are characterized by their ability to phagocytize…
Life sciencesNext-Generation Sequencing
Next Generation Sequencing (NGS) refers to various modern sequencing technologies that enable the rapid sequencing of large amounts of DNA. Unlike traditional sequencing techniques, which were slower…
Physical and Earth sciencesNitrogen Fixation
Nitrogen fixation is the biological process by which nitrogen gas (N₂) present in the atmosphere is converted into ammonia (NH₃) or other nitrogenous forms that are usable by living organisms. This…
Life sciencesNociceptor
Nociceptors are specialized sensory receptors that respond to stimuli that can cause tissue damage, such as extreme heat, intense pressure, or harmful chemicals. Their primary function is to detect…
Life sciencesNomenclatural Code
A nomenclatural code is a set of rules and recommendations for naming organisms, aimed at providing a standardized and universally accepted system for the identification of species and other…
Life sciencesNon-infectious gastroenteritis
Non-infectious gastroenteritis is the inflammation of the stomach and intestines not caused by infectious agents such as viruses, bacteria, or parasites. Instead, this condition is often the result…
Life sciencesNorovirus gastroenteritis
Norovirus gastroenteritis is a highly contagious viral infection that causes inflammation of the stomach and intestines. This virus, which belongs to the Caliciviridae family, is known for its…
Life sciencesNuclear DNA
Nuclear DNA refers to the genetic material found within the nucleus of eukaryotic cells. This type of DNA is fundamental for biological inheritance, as it contains the instructions necessary for the…
Life sciencesNuclear Envelope
The nuclear envelope is a double membrane that encloses the nucleus of a cell, separating the nuclear content from the cytoplasm. This structure is fundamental for cellular organization, as it not…
Life sciencesNuclear Genome
The nuclear genome is the genetic material contained within the nucleus of a cell. This genome is primarily composed of DNA (deoxyribonucleic acid), which is organized into structures called…
Life sciencesNuclear Pore Complex
The nuclear pore complex is a large protein complex that spans the nuclear envelope and regulates the transport of molecules between the nucleus and the cytoplasm of the cell. This complex is made up…
Life sciencesNuclear Receptor
Nuclear receptors are a class of proteins that regulate gene expression in response to hormones and other signaling molecules. These proteins are located in the cell nucleus and act as transcription…
Life sciencesNuclear Transfer
Nuclear transfer is a technique used in cloning where the nucleus of a donor cell is transferred to an egg cell. This process involves removing the nucleus from an egg, which is the female…
Life sciencesNucleic Acid
Nucleic acids are essential biopolymers for all known forms of life, including DNA and RNA. These complex molecules are composed of chains of nucleotides, which are the basic units containing a…
Life sciencesNucleotide
A nucleotide is the basic unit of nucleic acids, such as DNA and RNA. Each nucleotide consists of three main components: a phosphate group, a five-carbon sugar (ribose in the case of RNA and…
Life sciencesNucleotide Analog
Nucleotide analogs are molecules that resemble nucleotides, the basic units that make up nucleic acids such as DNA and RNA. These molecules can interfere with nucleic acid synthesis by being…
