A family of RNA viruses infecting a broad range of animals. Most individual species are restricted to their natural hosts. They possess a characteristic six-pointed starlike shape whose surfaces have cup-shaped (chalice) indentions. Transmission is by contaminated food, water, fomites, and occasionally aerosolization of secretions. Genera include LAGOVIRUS; NORWALK-LIKE VIRUSES; SAPPORO-LIKE VIRUSES; and VESIVIRUS.
Virus diseases caused by CALICIVIRIDAE. They include HEPATITIS E; VESICULAR EXANTHEMA OF SWINE; acute respiratory infections in felines, rabbit hemorrhagic disease, and some cases of gastroenteritis in humans.

A subfamily in the family CEBIDAE that consists of four genera: CALLITHRIX (marmosets), CALLIMICO (Goeldi's monkey), LEONTOPITHECUS (lion tamarins), and SAGUINUS (long-tusked tamarins). The members of this family inhabit the tropical forests of South and Central America.
Localized hyperplasia of the horny layer of the epidermis due to pressure or friction. (Dorland, 27th ed)
A plant genus of the family ERICACEAE.
A genus of SPONGES in the family Callyspongiidae comprised of a regular ectosomal reticulate skeleton.
A heat-stable, low-molecular-weight activator protein found mainly in the brain and heart. The binding of calcium ions to this protein allows this protein to bind to cyclic nucleotide phosphodiesterases and to adenyl cyclase with subsequent activation. Thereby this protein modulates cyclic AMP and cyclic GMP levels.
Proteins which bind calmodulin. They are found in many tissues and have a variety of functions including F-actin cross-linking properties, inhibition of cyclic nucleotide phosphodiesterase and calcium and magnesium ATPases.
A lectin found in ENDOPLASMIC RETICULUM membranes that binds to specific N-linked OLIGOSACCHARIDES found on newly synthesized proteins. It may play role in PROTEIN FOLDING or retention and degradation of misfolded proteins in the endoplasmic reticulum.
A plant genus of the family CLUSIACEAE. Members contain costatolide, calanolides and 4-phenylfuranocoumarins (FUROCOUMARINS).
Reduction in caloric intake without reduction in adequate nutrition. In experimental animals, caloric restriction has been shown to extend lifespan and enhance other physiological variables.
Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.
The measurement of the quantity of heat involved in various processes, such as chemical reactions, changes of state, and formations of solutions, or in the determination of the heat capacities of substances. The fundamental unit of measurement is the joule or the calorie (4.184 joules). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Differential thermal analysis in which the sample compartment of the apparatus is a differential calorimeter, allowing an exact measure of the heat of transition independent of the specific heat, thermal conductivity, and other variables of the sample.
Calculation of the energy expenditure in the form of heat production of the whole body or individual organs based on respiratory gas exchange.
A plant genus of the family ASCLEPIADACEAE. The downy akund floss fiber from the seeds is used like kapok.
Cysteine proteinase found in many tissues. Hydrolyzes a variety of endogenous proteins including NEUROPEPTIDES; CYTOSKELETAL PROTEINS; proteins from SMOOTH MUSCLE; CARDIAC MUSCLE; liver; platelets; and erythrocytes. Two subclasses having high and low calcium sensitivity are known. Removes Z-discs and M-lines from myofibrils. Activates phosphorylase kinase and cyclic nucleotide-independent protein kinase. This enzyme was formerly listed as EC 3.4.22.4.
A multifunctional protein that is found primarily within membrane-bound organelles. In the ENDOPLASMIC RETICULUM it binds to specific N-linked oligosaccharides found on newly-synthesized proteins and functions as a MOLECULAR CHAPERONE that may play a role in PROTEIN FOLDING or retention and degradation of misfolded proteins. In addition calreticulin is a major storage form for CALCIUM and functions as a calcium-signaling molecule that can regulate intracellular calcium HOMEOSTASIS.
Acidic protein found in SARCOPLASMIC RETICULUM that binds calcium to the extent of 700-900 nmoles/mg. It plays the role of sequestering calcium transported to the interior of the intracellular vesicle.
A plant family of the order Laurales, subclass Magnoliidae, class Magnoliopsida.
A genus of bacteria causing GRANULOMA INGUINALE and other granulomatous lesions.
A plant genus of the family CONVOLVULACEAE. Members contain calystegine and calystegins.
A suborder of nematodes characterized by larvae lacking cephalic hooks and a tail that is generally long and pointed.
A plant genus of the family Asparagaceae that contains steroidal SAPONINS and should not be confused with death camas (ZIGADENUS).
A nematocide effective against a variety of gastrointestinal parasites in cattle, sheep, and horses.
A layer of living cells between the bark and hardwood that each year produces additional wood and bark cells, forming concentric growth rings.
A country located in Southeastern Asia, bordering the Gulf of Thailand, between Thailand, Vietnam, and Laos. The capital is Phnom Penh.
Camelidae of the Americas. The extant species are those originating from South America and include alpacas, llamas, guanicos, and vicunas.
A plant genus in the family THEACEAE, order ERICALES best known for CAMELLIA SINENSIS which is the source of Oriental TEA.
Camellia sinensis L. (formerly Thea sinensis) is an evergreen Asiatic shrub of the THEACEAE family. The infusion of leaves of this plant is used as Oriental TEA which contains CAFFEINE; THEOPHYLLINE; and epigallocatechin gallate.

A plant family of the order Campanulales, subclass Asteridae, class Magnoliopsida
Crystalline saturated MONOTERPENES, precursors of borneols and CAMPHENE.
A bicyclic monoterpene ketone found widely in plants, especially CINNAMOMUM CAMPHORA. It is used topically as a skin antipruritic and as an anti-infective agent.
A soluble cytochrome P-450 enzyme that catalyzes camphor monooxygenation in the presence of putidaredoxin, putidaredoxin reductase, and molecular oxygen. This enzyme, encoded by the CAMC gene also known as CYP101, has been crystallized from bacteria and the structure is well defined. Under anaerobic conditions, this enzyme reduces the polyhalogenated compounds bound at the camphor-binding site.
Living outdoors as a recreational activity.
A congenital disorder of CHONDROGENESIS and OSTEOGENESIS characterized by hypoplasia of endochondral bones. In most cases there is a curvature of the long bones especially the TIBIA with dimpling of the skin over the bowed areas, malformation of the pelvis and spine, 11 pairs of ribs, hypoplastic scapulae, club feet, micrognathia, CLEFT PALATE, tracheobronchomalacia, and in some patients male-to-female sex reversal (SEX REVERSAL, GONADAL). Most patients die in the neonatal period of respiratory distress. Campomelic dysplasia is associated with haploinsufficiency of the SOX9 TRANSCRIPTION FACTOR gene.
