a beta-lactam sensor and signal transducer that leads to derepression of genes involved in inducible resistance
Persons having origins in any of the black racial groups of AFRICA. Note that OMB category BLACK OR AFRICAN AMERICAN is available for the United States population groups. Race and ethnicity terms, as used in the federal government, are self-identified social construct and may include terms outdated and offensive in MeSH to assist users who are interested in retrieving comprehensive search results for studies such as in longitudinal studies.
An inland sea between Europe and Asia. It is connected with the Aegean Sea by the Bosporus, the Sea of Marmara, and the Dardanelles.
A venomous New World spider with an hourglass-shaped red mark on the abdomen.
A person having origins in any of the black racial groups of Africa (https://www.federalregister.gov/documents/1997/10/30/97-28653/revisions-to-the-standards-for-the classification-of-federal-data-on-race-and-ethnicity). In the United States it is used for classification of federal government data on race and ethnicity. Race and ethnicity terms are self-identified social construct and may include terms outdated and offensive in MeSH to assist users who are interested in retrieving comprehensive search results for studies such as in longitudinal studies.
A complication of MALARIA, FALCIPARUM characterized by the passage of dark red to black urine.
A congenital diverticulum of the bladder with autosomal dominant inheritance. The diverticulum is usually located near the vesicoureteral junction and SCLEROSIS of the URETHRAL SPHINCTER with a prominent median bar of the PROSTATE occurs consistenly resulting in HEMATURIA in severe cases. Typical symptoms are bladder infection, urinary hesitancy, and DYSURIA. May also occur in EHLERS-DANLOS SYNDROME (OMIM: 130000). OMIM: 109820
A birth defect in which the URINARY BLADDER is malformed and exposed, inside out, and protruded through the ABDOMINAL WALL. It is caused by closure defects involving the top front surface of the bladder, as well as the lower abdominal wall; SKIN; MUSCLES; and the pubic bone.
A hereditary autosomal dominant type of severe bladder exstrophy characterized by the involvement of the infraumbilical abdominal, pelvis, urinary tract, and external genitalia. Affected patients experience URINARY INCONTINENCE; PHYSIOLOGICAL SEXUAL DYSFUNCTION, and chronic or recurring URINARY TRACT INFECTIONS that result in RENAL FAILURE. OMIM: 600057
Insertion of an endosseous implant with a narrow wedge-shaped infrastructure extending through the oral mucosa into the mouth and bearing openings or vents through which tissue grows to obtain retention.
A cardiovascular procedure performed to create a blood supply to the PULMONARY CIRCULATION. It involves making a connection between the subclavian, or carotid branch of the AORTA, or the AORTIC ARCH to the PULMONARY ARTERY.
A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.
An advanced phase of chronic myelogenous leukemia, characterized by a rapid increase in the proportion of immature white blood cells (blasts) in the blood and bone marrow to greater than 30%.
Injuries resulting when a person is struck by particles impelled with violent force from an explosion. Blast causes pulmonary concussion and hemorrhage, laceration of other thoracic and abdominal viscera, ruptured ear drums, and minor effects in the central nervous system. (From Dorland, 27th ed)
A genus of aquatic fungi of the family Blastocladiaceae, order Blastocladiales, used in the study of zoospore formation.
A phylum of flagellated fungi, formerly the order Blastocladiales under CHYTRIDIOMYCOTA.
A post-MORULA preimplantation mammalian embryo that develops from a 32-cell stage into a fluid-filled hollow ball of over a hundred cells. A blastocyst has two distinctive tissues. The outer layer of trophoblasts gives rise to extra-embryonic tissues. The inner cell mass gives rise to the embryonic disc and eventual embryo proper.
The cluster of cells inside a blastocyst. These cells give rise to the embryonic disc and eventual embryo proper. They are pluripotent EMBRYONIC STEM CELLS capable of yielding many but not all cell types in a developing organism.
A suborder of protozoa of the class LOBOSEA.
A genus of protozoa of the suborder BLASTOCYSTINA. It was first classified as a yeast but further studies have shown it to be a protozoan.
Infections with organisms of the genus BLASTOCYSTIS. The species B. hominis is responsible for most infections. Parasitologic surveys have generally found small numbers of this species in human stools, but higher positivity rates and organism numbers in AIDS patients and other immunosuppressed patients (IMMUNOCOMPROMISED HOST). Symptoms include ABDOMINAL PAIN; DIARRHEA; CONSTIPATION; VOMITING; and FATIGUE.
A species of parasitic protozoa found in the intestines of humans and other primates. It was classified as a yeast in 1912. Over the years, questions arose about this designation. In 1967, many physiological and morphological B. hominis characteristics were reported that fit a protozoan classification. Since that time, other papers have corroborated this work and the organism is now recognized as a protozoan parasite of humans causing intestinal disease with potentially disabling symptoms.
A layer of cells lining the fluid-filled cavity (blastocele) of a BLASTULA, usually developed from a fertilized insect, reptilian, or avian egg.
A small whitish spot on the surface of the EGG YOLK where cleavage begins. Upon fertilization the cytoplasm streams from the vegetal pole away from the yolk to the animal pole where cleavage will occur. This germinal area eventually flattens into a layer of cells (BLASTODERM) that covers the yolk completely.
Undifferentiated cells resulting from cleavage of a fertilized egg (ZYGOTE). Inside the intact ZONA PELLUCIDA, each cleavage yields two blastomeres of about half size of the parent cell. Up to the 8-cell stage, all of the blastomeres are totipotent. The 16-cell MORULA contains outer cells and inner cells.
A genus of onygenacetous mitosporic fungi whose perfect state is Ajellomyces (see ONYGENALES). The species Blastomyces dermatitidis (perfect state is Ajellomyces dermatitidis) causes blastomycosis.
A fungal infection by BLASTOMYCES that may appear in two forms: 1, a primary lesion characterized by the formation of a small cutaneous nodule and small nodules along the lymphatics that may heal within several months; and 2, chronic granulomatous lesions characterized by thick crusts, warty growths, and unusual vascularity and infection in the middle or upper lobes of the lung.
An early non-mammalian embryo that follows the MORULA stage. A blastula resembles a hollow ball with the layer of cells surrounding a fluid-filled cavity (blastocele). The layer of cells is called BLASTODERM.
A family of insects in the order Dictyoptera (COCKROACHES), including genera Blattella, Parcoblatta, and Symploce.
Chemicals that are used to oxidize pigments and thus effect whitening.
mutation in P2RY12
Duration of blood flow after skin puncture. This test is used as a measure of capillary and platelet function.
A complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors.
Inflammation of the eyelids.
