All individuals in MESHD

Label	Id	Description
Neoplasms, Vascular Tissue	D009383	[Neoplasms composed of vascular tissue. This concept does not refer to neoplasms located in blood vessels.]
Neoplastic Cells, Circulating	D009360	[Exfoliate neoplastic cells circulating in the blood and associated with metastasizing tumors.]
Neoplastic Processes	D009385	[The pathological mechanisms and forms taken by tissue during degeneration into a neoplasm and its subsequent activity.]
Neoplastic Syndromes, Hereditary	D009386	[The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the tumor tends to occur at an earlier than average age, individuals may have more than one primary tumor, the tumors may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance.]
Neovascularization, Pathologic	D009389	[A pathologic process consisting of the proliferation of blood vessels in abnormal tissues or in abnormal positions.]
Nephritis	D009393	[Inflammation of any part of the KIDNEY.]
Nephritis, Hereditary	D009394	[A group of inherited conditions characterized initially by HEMATURIA and slowly progressing to RENAL INSUFFICIENCY. The most common form is the Alport syndrome (hereditary nephritis with HEARING LOSS) which is caused by mutations in genes for TYPE IV COLLAGEN and defective GLOMERULAR BASEMENT MEMBRANE.]
Nephritis, Interstitial	D009395	[Inflammation of the interstitial tissue of the kidney. This term is generally used for primary inflammation of KIDNEY TUBULES and/or surrounding interstitium. For primary inflammation of glomerular interstitium, see GLOMERULONEPHRITIS. Infiltration of the inflammatory cells into the interstitial compartment results in EDEMA, increased spaces between the tubules, and tubular renal dysfunction.]
Nephrocalcinosis	D009397	[A condition characterized by calcification of the renal tissue itself. It is usually seen in distal RENAL TUBULAR ACIDOSIS with calcium deposition in the DISTAL KIDNEY TUBULES and the surrounding interstitium. Nephrocalcinosis causes RENAL INSUFFICIENCY.]
Nephrogenic Fibrosing Dermopathy	D054989	[A chronic, acquired, idiopathic, progressive eruption of the skin that occurs in the context of RENAL FAILURE. It is sometimes accompanied by systemic fibrosis. The pathogenesis seems to be multifactorial, with postulated involvement of circulating fibrocytes. There is a strong association between this disorder and the use of gadolinium-based contrast agents.]
Nephrolithiasis	D053040	[Formation of stones in the KIDNEY.]
Nephroma, Mesoblastic	D018201	[A solid, unencapsulated tumor of the KIDNEY composed of spindle mesenchymal cells that resemble FIBROBLASTS or muscle cells. The homogeneous mass typically extends into the renal parenchyma and replaces most of the kidney. In most cases, mesoblastic nephroma is benign and occurs in the fetus or newborn, and rarely in the older child or the adult.]
Nephrosclerosis	D009400	[Hardening of the KIDNEY due to infiltration by fibrous connective tissue (FIBROSIS), usually caused by renovascular diseases or chronic HYPERTENSION. Nephrosclerosis leads to renal ISCHEMIA.]
Nephrosis	D009401	[Pathological processes of the KIDNEY without inflammatory or neoplastic components. Nephrosis may be a primary disorder or secondary complication of other diseases. It is characterized by the NEPHROTIC SYNDROME indicating the presence of PROTEINURIA and HYPOALBUMINEMIA with accompanying EDEMA.]
Nephrosis, Lipoid	D009402	[A kidney disease with no or minimal histological glomerular changes on light microscopy and with no immune deposits. It is characterized by lipid accumulation in the epithelial cells of KIDNEY TUBULES and in the URINE. Patients usually show NEPHROTIC SYNDROME indicating the presence of PROTEINURIA with accompanying EDEMA.]
Nephrotic Syndrome	D009404	[A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.]
Nerve Compression Syndromes	D009408	[Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.]
Nerve Degeneration	D009410	[Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.]
Nerve Sheath Neoplasms	D018317	[Neoplasms which arise from nerve sheaths formed by SCHWANN CELLS in the PERIPHERAL NERVOUS SYSTEM or by OLIGODENDROCYTES in the CENTRAL NERVOUS SYSTEM. Malignant peripheral nerve sheath tumors, NEUROFIBROMA, and NEURILEMMOMA are relatively common tumors in this category.]
Nervous System Autoimmune Disease, Experimental	D020721	[Experimental animal models for human AUTOIMMUNE DISEASES OF THE NERVOUS SYSTEM. They include GUILLAIN-BARRE SYNDROME (see NEURITIS, AUTOIMMUNE, EXPERIMENTAL); MYASTHENIA GRAVIS (see MYASTHENIA GRAVIS, AUTOIMMUNE, EXPERIMENTAL); and MULTIPLE SCLEROSIS (see ENCEPHALOMYELITIS, AUTOIMMUNE, EXPERIMENTAL).]
