A visual impairment characterized by the accumulation of fluid under the retina through a defect in the retinal pigment epithelium.
Hospital department responsible for receiving, storing, and distributing medical and surgical supplies and equipment.
The mechanism, in central lymphoid organs (THYMUS; BONE MARROW), that prevents immature lymphocytes from reacting to SELF-ANTIGENS. This is accomplished by CLONAL ANERGY and CLONAL DELETION.
Catheters that are inserted into a large central vein such as a SUBCLAVIAN VEIN or FEMORAL VEIN.
The blood pressure in the central large VEINS of the body. It is distinguished from peripheral venous pressure which occurs in an extremity.
The coordination of services in one area of a facility to improve efficiency.
The location of the maxillary and the mandibular condyles when they are in their most posterior and superior positions in their fossae of the temporomandibular joint.
Process of using a rotating machine to generate centrifugal force to separate substances of different densities, remove moisture, or simulate gravitational effects. It employs a large motor-driven apparatus with a long arm, at the end of which human and animal subjects, biological specimens, or equipment can be revolved and rotated at various speeds to study gravitational effects. (From Websters, 10th ed; McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Separation of particles according to density by employing a gradient of varying densities. At equilibrium each particle settles in the gradient at a point equal to its density. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
A technique used to separate particles according to their densities in a continuous density gradient. The sample is usually mixed with a solution of known gradient materials and subjected to centrifugation. Each particle sediments to the position at which the gradient density is equal to its own. The range of the density gradient is usually greater than that of the sample particles. It is used in purifying biological materials such as proteins, nucleic acids, organelles, and cell types.
Centrifugation using a rotating chamber of large capacity in which to separate cell organelles by density-gradient centrifugation. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Self-replicating, short, fibrous, rod-shaped organelles. Each centriole is a short cylinder containing nine pairs of peripheral microtubules, arranged so as to form the wall of the cylinder.
The clear constricted portion of the chromosome at which the chromatids are joined and by which the chromosome is attached to the spindle during cell division.
A DNA-binding protein that interacts with a 17-base pair sequence known as the CENP-B box motif. The protein is localized constitutively to the CENTROMERE and plays an important role in its maintenance.
An organelle near the nucleus of the cell consisting (in animals and organisms that have CILIA) of two CENTRIOLES, and the surrounding pericentriolar material. It functions as the primary MICROTUBULE-ORGANIZING CENTER during the eukaryotic CELL CYCLE (https://doi.org/10.1038/nrm2180).

A derivative of 7-aminocephalosporanic acid.
A plant genus of the family RUBIACEAE, order Rubiales, subclass Asteridae. Cephaelis ipecacuanha is the source of IPECAC.
A semisynthetic cephalosporin antibiotic with antimicrobial activity similar to that of CEPHALORIDINE or CEPHALOTHIN, but somewhat less potent. It is effective against both gram-positive and gram-negative organisms.
A subphylum of chordates intermediate between the invertebrates and the true vertebrates. It includes the LANCELETS. Its members are characterized by a NOTOCHORD which extends into the adult stage head.
A cephalorsporin antibiotic.
The measurement of the dimensions of the HEAD.
A condition in which the HEAD of the FETUS is larger than the mother's PELVIS through which the fetal head must pass during a vaginal delivery.
A class in the phylum MOLLUSCA comprised of SQUID; CUTTLEFISH; OCTOPUS; and NAUTILUS. These marine animals are the most highly organized of all the mollusks.
A cephalosporin antibiotic.
Non-susceptibility of an organism to the action of the cephalosporins.
A group of broad-spectrum antibiotics first isolated from the Mediterranean fungus ACREMONIUM. They contain the beta-lactam moiety thia-azabicyclo-octenecarboxylic acid also called 7-aminocephalosporanic acid.
A plant genus of the family TAXACEAE, order Pinales, class Pinopsida, division TRACHEOPHYTA. Members contain homoharringtonine.
A cephalosporin antibiotic.
Naturally occurring family of beta-lactam cephalosporin-type antibiotics having a 7-methoxy group and possessing marked resistance to the action of beta-lactamases from gram-positive and gram-negative organisms.
Cephalosporin antibiotic, partly plasma-bound, that is effective against gram-negative and gram-positive organisms.
A semi-synthetic cephalosporin antibiotic.
Products made by baking or firing nonmetallic minerals (clay and similar materials). In making dental restorations or parts of restorations the material is fused porcelain. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed and Boucher's Clinical Dental Terminology, 4th ed)
Amidohydrolases that are specific for the cleavage of the N-acyl linkage of CERAMIDES. Ceramidases are classified as acidic, neutral or basic according to the optimal pH with which they function.
Members of the class of neutral glycosphingolipids. They are the basic units of SPHINGOLIPIDS. They are sphingoids attached via their amino groups to a long chain fatty acyl group. They abnormally accumulate in FABRY DISEASE.
A species of fruit fly originating in sub-Saharan Africa but widely distributed worldwide. One of the most destructive fruit pests, its larvae feed and develop on many different fruits and some vegetables.
A family of biting midges, in the order DIPTERA. It includes the genus Culicoides which transmits filarial parasites (e.g., MANSONELLA PERSTANS) causing MANSONELLIASIS. Culicoides paraensis is the primary vector for OROPOUCHE VIRUS INFECTION in the Americas.
The free-swimming larval forms of parasites found in an intermediate host.
