Albinism has frequently occurred in progeny of Black Tartarian, Bing and Hedelfingen varieties of sweet cherry.Some herbicides (e.g. glyphosate and triazines) can cause partial chlorosis in plants, even several seasons or years after applicating. In human culture
The Albino Squirrel Preservation Society was founded at the University of Texas at Austin in 2001. Members of the society at the University of North Texas petitioned for an election to name their albino squirrel as the universitys secondary mascot. The University of Louisville in Kentucky also has a documented population of albino squirrels.Albino animals are often kept as pets, for example, African clawed frog, guinea pigs and peacocks.

Acute administration of drugs should be followed by several hours of observation to ensure that blood pressure does not fall too much. Aggressive dosing with intravenous drugs or oral agents which lowers blood pressure too rapidly carries risk; conversely there is no evidence that failure to rapidly lower blood pressure in a hypertensive urgency is associated with any increased short-term risk. Epidemiology
Not much is known about the epidemiology of hypertensive urgencies. Retrospective analysis of data from 1,290,804 adults admitted to hospital emergency departments in United States from 2005 through 2007 found that severe hypertension with a systolic blood pressure ≥180 mmHg occurred in 13.8% of patients. Based on another study in a US public teaching hospital about 60% of hypertensive crises are due to hypertensive urgencies.Risk factors for severe hypertension include older age, female sex, obesity, coronary artery disease, somatoform disorder, being prescribed multiple antihypertensive medications, and non-adherence to medication. == References ==
