Monocytosis is an increase in the number of monocytes circulating in the blood. [1] Monocytes are white blood cells that give rise to macrophages and dendritic cells in the immune system. In humans, monocytosis occurs when there is a sustained rise in monocyte counts greater than 800/mm 3 to 1000/mm 3 .
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Thus, the element's natural isotopic abundance is dominated by one isotope that is either stable or very long-lived. There are 19 elements in the first category (which are both monoisotopic and mononuclidic), and 2 ( bismuth [ a ] and protactinium ) in the second category (mononuclidic but not monoisotopic, since they have zero, not one, stable ...
The following is a list of the causes of human deaths worldwide for different years arranged by their associated mortality rates. In 2002, there were about 57 million deaths. In 2002, there were about 57 million deaths.
The population of the mountain chicken frog, once abundant in the Caribbean, has dropped by over 99% in 20 years due to a deadly fungal disease.
This is a list of the deadliest animals to humans worldwide, measured by the number of humans killed per year. Different lists have varying criteria and definitions, so lists from different sources disagree and can be contentious. This article contains a compilation of lists from several reliable sources.
Those viruses became deadly human contagions and spread in animals and people. A number of experts think it’s unlikely this virus will become a deadly global contagion, based on current evidence ...
