Biotechnology
|
D001709 |
[Body of knowledge related to the use of organisms, cells or cell-derived constituents for the purpose of developing products which are technically, scientifically and clinically useful. Alteration of biologic function at the molecular level (i.e., GENETIC ENGINEERING) is a central focus; laboratory methods used include TRANSFECTION and CLONING technologies, sequence and structure analysis algorithms, computer databases, and gene and protein structure function analysis and prediction.

Biotin
|
D001710 |
[A water-soluble, enzyme co-factor present in minute amounts in every living cell. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk.

|
Biotinidase
|
D043523 |
[An enzyme which catalyzes the release of BIOTIN from biocytin. In human, defects in the enzyme are the cause of the organic acidemia MULTIPLE CARBOXYLASE DEFICIENCY or BIOTINIDASE DEFICIENCY.

|
Biotinidase Deficiency
|
D028921 |
[The late onset form of MULTIPLE CARBOXYLASE DEFICIENCY (deficiency of the activities of biotin-dependent enzymes propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and PYRUVATE CARBOXYLASE) due to a defect or deficiency in biotinidase which is essential for recycling BIOTIN.

Biotinylation
|
D019921 |
[Incorporation of biotinyl groups into molecules.

|
Biotransformation
|
D001711 |
[The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.

Biperiden
|
D001712 |
[A muscarinic antagonist that has effects in both the central and peripheral nervous systems. It has been used in the treatment of arteriosclerotic, idiopathic, and postencephalitic parkinsonism. It has also been used to alleviate extrapyramidal symptoms induced by phenothiazine derivatives and reserpine.

Biphasic Insulins
|
D061265 |
[An insulin preparation that is designed to provide immediate and long term glycemic control in a single dosage. Biphasic insulin typically contains a mixture of REGULAR INSULIN or SHORT-ACTING INSULIN combined with a LONG-ACTING INSULIN.

|
Bipolaris
|
D000084727 |
[A genus of fungi in the family Pleosporaceae, order Pleosporales and phylum ASCOMYCOTA. Bipolaris fungi are ascomycetes and plant pathogens, mostly on POACEAE and some monocot crops. They are also causative agent for PHAEOHYPHOMYCOSIS and were formerly a part of Bipolaris, Cochliobolus and CURVULARIA complex.

Bird Diseases
|
D001715 |
[Diseases of birds not considered poultry, therefore usually found in zoos, parks, and the wild. The concept is differentiated from POULTRY DISEASES which is for birds raised as a source of meat or eggs for human consumption, and usually found in barnyards, hatcheries, etc.

Bird Fancier's Lung
|
D001716 |
[A form of alveolitis or pneumonitis due to an acquired hypersensitivity to inhaled avian antigens, usually proteins in the dust of bird feathers and droppings.

Birdshot Chorioretinopathy
|
D000080365 |
[A form of chorioretinitis characterized by multiple small, cream-colored LESIONS, symmetrically scattered mainly around the OPTIC DISK. These lesions are the most distinctive sign and often appear at the level of the RETINAL PIGMENT EPITHELIUM but, on occasion, suggest an even deeper infiltration and may ultimately lead to visual loss. An association with HLA-A29 antigen (see HLA-A ANTIGENS) has been observed in nearly all patients.
