Nystagmus, Pathologic
|
D009759 |
[Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life. (Adams et al., Principles of Neurology, 6th ed, p272)

Nystagmus, Physiologic
|
D009760 |
[Involuntary rhythmical movements of the eyes in the normal person. These can be naturally occurring as in end-position (end-point, end-stage, or deviational) nystagmus or induced by the optokinetic drum (NYSTAGMUS, OPTOKINETIC), caloric test, or a rotating chair.

O Antigens
|
D019081 |
[The lipopolysaccharide-protein somatic antigens, usually from gram-negative bacteria, important in the serological classification of enteric bacilli. The O-specific chains determine the specificity of the O antigens of a given serotype. O antigens are the immunodominant part of the lipopolysaccharide molecule in the intact bacterial cell.

O(6)-Methylguanine-DNA Methyltransferase
|
D019853 |
[An enzyme that transfers methyl groups from O(6)-methylguanine, and other methylated moieties of DNA, to a cysteine residue in itself, thus repairing alkylated DNA in a single-step reaction. EC 2.1.1.63.

O-Acetyl-ADP-Ribose
|
D038961 |
[An acetyl ester of ADENOSINE DIPHOSPHATE RIBOSE formed during NAD-dependent deacetylation of proteins by SIRTUINS. The acetate group resides on the ribose ring where nicotinamide was cleaved from NAD during the reaction. Several isomers of O-acetyl-ADP-ribose have been isolated from the reaction.

|
ORAI2 Protein
|
D000071741 |
[A calcium release-activated calcium-like (CRAC-like) channel subunit which functions with STROMAL INTERACTION MOLECULE 1 to regulate cell calcium influx and increase (Ca2+)-selective current.

OX40 Ligand
|
D053278 |
[A membrane-bound tumor necrosis family member that is expressed on activated antigen-presenting cells such as B-LYMPHOCYTES and MACROPHAGES. It signals T-LYMPHOCYTES by binding the OX40 RECEPTOR.

Obesity
|
D009765 |
[A status with BODY WEIGHT that is grossly above the acceptable or desirable weight, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).

Obesity Hypoventilation Syndrome
|
D010845 |
[HYPOVENTILATION syndrome in very obese persons with excessive ADIPOSE TISSUE around the ABDOMEN and DIAPHRAGM. It is characterized by diminished to absent ventilatory chemoresponsiveness; chronic HYPOXIA; HYPERCAPNIA; POLYCYTHEMIA; and long periods of sleep during day and night (HYPERSOMNOLENCE). It is a condition often related to OBSTRUCTIVE SLEEP APNEA but can occur separately.

Obesity, Abdominal
|
D056128 |
[Obesity due to excessive deposition of INTRA-ABDOMINAL FAT in the abdominal VISCERA and OMENTUM.
, A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as DIABETES; HYPERTENSION; and METABOLIC SYNDROME.
