El asesino silencioso: a methodology for alerting the Spanish-speaking community
Abstract:
Information describing the health status of the Spanish-speaking population, the nation's second largest minority, is extremely scarce. In particular, few studies have attempted to document the prevalence or ascertain the extent of treatment or the level of public awareness of hypertension or other cardiovascular diseases in this minority population. However, before any large scale effort to determine the prevalence or to determine the treatment and awareness needs related to hypertension is initiated, preliminary questions concerning how to reach and motivate the Spanish-speaking population to adopt cardiovascular health risk-reducing behaviors must be answered.

Small interfering RNAs (siRNA)
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...
