A genus of aerobic or facultatively anaerobic BACTERIA, in the family Cellulomonadaceae. It is found in the SOIL and capable of hydrolyzing CELLULOSE.
A polysaccharide with glucose units linked as in CELLOBIOSE. It is the chief constituent of plant fibers, cotton being the purest natural form of the substance. As a raw material, it forms the basis for many derivatives used in chromatography, ion exchange materials, explosives manufacturing, and pharmaceutical preparations.
An exocellulase with specificity for the hydrolysis of 1,4-beta-D-glucosidic linkages in CELLULOSE and cellotetraose. It catalyzes the hydrolysis of terminal non-reducing ends of beta-D-glucosides with release of CELLOBIOSE.
A cellulose of varied carboxyl content retaining the fibrous structure. It is commonly used as a local hemostatic and as a matrix for normal blood coagulation.
Extracellular structures found in a variety of microorganisms. They contain CELLULASES and play an important role in the digestion of CELLULOSE.
A genus of aerobic, gram-negative, motile, slightly curved, rod-shaped bacteria. (From Bergey's Manual of Determinative Bacteriology, 9th ed)
A plant genus of the family AMARANTHACEAE. Young leaves are used as vegetables in Asia. Members contain betacyanins, celogentins, betaxanthin, and celosian.

The joining of objects by means of a cement (e.g., in fracture fixation, such as in hip arthroplasty for joining of the acetabular component to the femoral component). In dentistry, it is used for the process of attaching parts of a tooth or restorative material to a natural tooth or for the attaching of orthodontic bands to teeth by means of an adhesive.
The formation of DENTAL CEMENTUM, a bone-like material that covers the root of the tooth.
An odontogenic fibroma in which cells have developed into cementoblasts and which consists largely of cementum.
Injection of BONE CEMENTS into bone to treat bone lesions.
Areas set apart as burial grounds.
A plant genus of the family POACEAE. The common name of buffelgrass is also used for PENNISETUM.
RefSeq NM_001014996
Enumerations of populations usually recording identities of all persons in every place of residence with age or date of birth, sex, occupation, national origin, language, marital status, income, relation to head of household, information on the dwelling place, education, literacy, health-related data (e.g., permanent disability), etc. The census or numbering of the people is mentioned several times in the Old Testament. Among the Romans, censuses were intimately connected with the enumeration of troops before and after battle and probably a military necessity. (From Last, A Dictionary of Epidemiology, 3d ed; Garrison, An Introduction to the History of Medicine, 4th ed, p66, p119)
A plant genus of the family ASTERACEAE. Members contain 5-methyl-8-hydroxycoumarin. The common name of centaury is more often used for CENTAURIUM
A plant genus of the family GENTIANACEAE. Triterpene lactones and other compounds have been isolated from species of this genus. The common name of century plant has also been used for the AGAVE genus.
A non-steroidal anti-fertility agent with anti-hormonal properties.
A plant of the family APIACEAE which is the source of asiatic acid and asiaticoside. Centella asiatica (L.) Urb. = Hydrocotyle asiatica L. is known for effect on peripheral circulation.
An agency of the UNITED STATES PUBLIC HEALTH SERVICE that conducts and supports programs for the prevention and control of disease and provides consultation and assistance to health departments and other countries.
A component of the Department of Health and Human Services to oversee and direct the Medicare and Medicaid programs and related Federal medical care quality control staffs. Name was changed effective June 14, 2001.
A republic in central Africa south of CHAD and SUDAN, north of DEMOCRATIC REPUBLIC OF THE CONGO, and east of CAMEROON. The capital is Bangui.
A region of southern NORTH AMERICA extending from the southern border of MEXICO to the northern border of COLOMBIA. It separates the Caribbean Sea from the Pacific Ocean and is linked to SOUTH AMERICA by the Isthmus of Panama.
A nucleus located in the caudal half of the amygdala. It is a primary region involved in controlling responses and receives many intrinsic GABAergic amygdaloid connections.
A syndrome associated with traumatic injury to the cervical or upper thoracic regions of the spinal cord characterized by weakness in the arms with relative sparing of the legs and variable sensory loss. This condition is associated with ischemia, hemorrhage, or necrosis involving the central portions of the spinal cord. Corticospinal fibers destined for the legs are spared due to their more external location in the spinal cord. This clinical pattern may emerge during recovery from spinal shock. Deficits may be transient or permanent.
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
A class of drugs producing both physiological and psychological effects through a variety of mechanisms. They can be divided into specific agents, e.g., affecting an identifiable molecular mechanism unique to target cells bearing receptors for that agent, and nonspecific agents, those producing effects on different target cells and acting by diverse molecular mechanisms. Those with nonspecific mechanisms are generally further classed according to whether they produce behavioral depression or stimulation. Those with specific mechanisms are classed by locus of action or specific therapeutic use. (From Gilman AG, et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p252)
Bacterial infections of the brain, spinal cord, and meninges, including infections involving the perimeningeal spaces.
Congenital or acquired cysts of the brain, spinal cord, or meninges which may remain stable in size or undergo progressive enlargement.
A very loosely defined group of drugs that tend to reduce the activity of the central nervous system. The major groups included here are ethyl alcohol, anesthetics, hypnotics and sedatives, narcotics, and tranquilizing agents (antipsychotics and antianxiety agents).
Diseases of any component of the brain (including the cerebral hemispheres, diencephalon, brain stem, and cerebellum) or the spinal cord.
MYCOSES of the brain, spinal cord, and meninges which may result in ENCEPHALITIS; MENINGITIS, FUNGAL; MYELITIS; BRAIN ABSCESS; and EPIDURAL ABSCESS. Certain types of fungi may produce disease in immunologically normal hosts, while others are classified as opportunistic pathogens, causing illness primarily in immunocompromised individuals (e.g., ACQUIRED IMMUNODEFICIENCY SYNDROME).
Infections of the BRAIN; SPINAL CORD; or MENINGES caused by HELMINTHS (parasitic worms).
Pathogenic infections of the brain, spinal cord, and meninges. DNA VIRUS INFECTIONS; RNA VIRUS INFECTIONS; BACTERIAL INFECTIONS; MYCOPLASMA INFECTIONS; SPIROCHAETALES INFECTIONS; fungal infections; PROTOZOAN INFECTIONS; HELMINTHIASIS; and PRION DISEASES may involve the central nervous system as a primary or secondary process.
Benign and malignant neoplastic processes that arise from or secondarily involve the brain, spinal cord, or meninges.
Infections of the brain, spinal cord, and meninges caused by parasites.
Infections of the brain, spinal cord, or meninges by single celled organisms of the former subkingdom known as protozoa. The central nervous system may be the primary or secondary site of protozoal infection. These diseases may occur as OPPORTUNISTIC INFECTIONS or arise in immunocompetent hosts.
An increased response to stimulation that is mediated by amplification of signaling in the CENTRAL NERVOUS SYSTEM (CNS).
A loosely defined group of drugs that tend to increase behavioral alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here.
Congenital, inherited, or acquired abnormalities involving ARTERIES; VEINS; or venous sinuses in the BRAIN; SPINAL CORD; and MENINGES.
A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
Viral infections of the brain, spinal cord, meninges, or perimeningeal spaces.
Networks of nerve cells that control the firing patterns of MOTOR NEURONS to produce rhythmic movements such as MASTICATION; WALKING; SWIMMING; RESPIRATION; and PERISTALSIS.
