A disease can be defined as "any deviation from a normal or healthy condition". As such there are many kinds of disease and a few approaches one may elect to delineate them. By their etiologies (causative mechanisms), treatment approaches, appearances'¦ I have chosen the first. Environmenta...
Plant disease, an impairment of the normal state of a plant that interrrupts or modifies its vital functions. Plant diseases can be classified as infectious or noninfectious, depending on the causative agent. Learn more about the importance, transmission
Myelination is often compromised in ATR-X intellectual disability syndrome patients. Here, the authors show that the causative gene, ATRX, can regulate myelination in mice by modulating systemic thyroxine levels and by supporting oligodendrocyte progenitor differentiation. ...
Diseases of animals remain a concern principally because of the economic losses they cause and the possible transmission of the causative agents to humans. The branch of medicine called veterinary medicine deals with the study, prevention, and treatment of diseases not only in domesticated animals ...
organisms [24]. Risk factors include hypoxia-inducing contact lens wear, while agricultural and other ocular trauma is a more common predisposing factor in resource-poor countries. In a proportion of cases, it is bilateral, notably in neonatal conjunctivitis where the causative pathogen may be...
Sickle cell disease (SCD) is a group of genetic disorders in which an abnormal hemoglobin molecule (hemoglobin S) transforms red blood cells into a “sickle-shaped” cell.
Obesity in Prader–Willi syndrome commonly has a central predisposition (abdomen, hips, thighs) in both genders and is usually the main causative factor behind morbidity and mortality associated with this disease. The current literature reports higher levels for orexigenic hormone (ghrelin) in PWS ...
Cultures for causative organisms for PIDAdditional STI tests: HIV , syphilis Pregnancy test (to rule out ectopic pregnancy )Imaging:Transvaginal ultrasound if clinical and laboratory findings inconclusive or complications suspected May show thickened fallopian tube , free pelvic fluid, or indistinct ...
Unlike the genes that predispose to autoimmunity, the environmental factors that can act as triggers are more difficult to ascertain. One reason is the large number of potentially causative factors given the ubiquity of infective organisms and chemical agents in the environment. The time element is...
