Contribution of neutrophil/lymphocyte ratio to the diagnostic efficiency of computed tomography and polymerase chain reaction in COVID-19 patients

SAGE Open Medicine, 2021
Background: 6.5% of the country’s population was diagnosed with COVID-19 disease. Computed tomography scanning and polymerase chain reaction tests are considered reliable methods for the detection of COVID-19.

Validation of a Polymerase Chain Reaction technique for Kidd blood group genotyping [PDF]

, 2015
The Kidd blood group antigens, Jkª and Jkᵇ , are two of the main surface markers which are found on the membrane of red blood cells. The determination of whether a donor or a recipient has the Jkª and/or the Jkᵇ antigens is crucially important to ...

Semi-quantitative digital analysis of polymerase chain reactionelectrophoresis gel: Potential applications in low-income veterinary laboratories [PDF]

Veterinary World, 2016
Aim: The interpretation of conventional polymerase chain reaction (PCR) assay results is often limited to either positive or negative (non-detectable). The more robust quantitative PCR (qPCR) method is mostly reserved for quantitation studies and not a ...

Computing by polymerase chain reaction [PDF]

Mathematical Biosciences, 2008
A mathematical notation is introduced to represent, at a symbolic level, different mechanisms of DNA recombination, and a 'PCR lemma' is proven by analytically describing the combinatorial properties of the polymerase chain reaction process. This approach led to the discovery of novel techniques, based on a form of PCR which we called cross pairing PCR

Efficiency of polymerase chain reaction processes: A stochastic model [PDF]

, 2006
A stochastic model for the efficiency of polymerase chain reaction (PCR) processes is presented. The model is based on the assumption that the i’th nucleotide incorporation on the DNA template takes τi seconds, where τi has an exponential distribution ...
