Conditions caused by abnormal CILIA movement in the body, usually causing KARTAGENER SYNDROME, chronic respiratory disorders, chronic SINUSITIS, and chronic OTITIS. Abnormal ciliary beating is likely due to defects in any of the 200 plus ciliary proteins, such as missing motor enzyme DYNEIN arms.
A neurotrophic factor that promotes the survival of various neuronal cell types and may play an important role in the injury response in the nervous system.
A ciliary neurotrophic factor receptor subunit. It is anchored to the cell surface via GLYCOSYLPHOSPHATIDYLINOSITOL LINKAGE and has specificity for binding to CILIARY NEUROTROPHIC FACTOR. It lacks signal transducing domains which are found on the other two subunits of the receptor.
A phylum of EUKARYOTES characterized by the presence of cilia at some time during the life cycle. It comprises three classes: KINETOFRAGMINOPHOREA; OLIGOHYMENOPHOREA; and POLYMENOPHOREA.
Infections with protozoa of the phylum CILIOPHORA.
a PET radioligand; structure in first source
A histamine congener, it competitively inhibits HISTAMINE binding to HISTAMINE H2 RECEPTORS. Cimetidine has a range of pharmacological actions. It inhibits GASTRIC ACID secretion, as well as PEPSIN and GASTRIN output.
A family of wingless, blood-sucking insects of the suborder HETEROPTERA, including the bedbugs and related forms. Cimex (BEDBUGS), Heamatosiphon, and Oeciacus are medically important genera. (From Dorland, 28th ed)
A plant genus of the family RANUNCULACEAE that contains triterpenoid saponins. Remifemin from C. racemosa is used to suppress LUTEINIZING HORMONE. It is reclassified by some to ACTAEA. The common name of black snakeroot is also used with ASARUM and SANICULA.
A serotonin antagonist with limited antihistaminic, anticholinergic, and immunosuppressive activity.
A genus of rubiaceous South American trees that yields the toxic CINCHONA ALKALOIDS from their bark; QUININE; QUINIDINE; chinconine, cinchonidine and others are used to treat MALARIA and CARDIAC ARRHYTHMIAS.
Alkaloids extracted from various species of Cinchona.
Motion pictures of the passage of contrast medium through blood vessels.
Motion picture study of successive images appearing on a fluoroscopic screen.
Derivatives of cinnamic acid (the structural formula: phenyl-HC=CH-COO-), including its salts and esters.
A plant genus in the LAURACEAE family. The bark of the trees is used in FOLK MEDICINE and FLAVORING AGENTS.
A plant species of the genus CINNAMOMUM that contains CINNAMATES and has been used in traditional Chinese medicine (DRUGS, CHINESE HERBAL).
A tree, Cinnamomum camphora (L.) J. Presl, known as the source of CAMPHOR.
The tree which is known for its bark which is sold as cinnamon. The oil contains about 65-80% cinnamaldehyde and 10% EUGENOL and many TERPENES.
A piperazine derivative having histamine H1-receptor and calcium-channel blocking activity with vasodilating and antiemetic properties but it induces PARKINSONIAN DISORDERS.
Synthetic antimicrobial related to OXOLINIC ACID and NALIDIXIC ACID and used in URINARY TRACT INFECTIONS.
Vase or tube shaped TUNICATES with a cosmopolitan distribution.
A broad-spectrum antimicrobial carboxyfluoroquinoline.

Biological mechanism that controls CIRCADIAN RHYTHM. Circadian clocks exist in the simplest form in cyanobacteria and as more complex systems in fungi, plants, and animals. In humans the system includes photoresponsive RETINAL GANGLION CELLS and the SUPRACHIASMATIC NUCLEUS that acts as the central oscillator.
The regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs or environmental and physiological stimuli.
A broad category of proteins that regulate the CIRCADIAN RHYTHM of an organism. Included here are proteins that transmit intracellular and intercellular signals in a chronological manner along with proteins that sense light and time-dependent changes in the environment such as the PHOTOPERIOD.
A polygonal anastomosis at the base of the brain formed by the internal carotid (CAROTID ARTERY, INTERNAL), proximal parts of the anterior, middle, and posterior cerebral arteries (ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; POSTERIOR CEREBRAL ARTERY), the anterior communicating artery and the posterior communicating arteries.
A family of very small viruses containing circular, single-stranded DNA and possessing no envelope. The modes of transmission are not known.
Virus diseases caused by the CIRCOVIRIDAE.
