Lamarck and immunity: Somatic and germline evolution of antibody genes [PDF]

open access: yes, 2009
Current work on the mechanism of hypermutation of somatically rearranged antibody variable (V) genes shows that the most likely mechanism involves both direct DNA modification (deamination of cytosines to uracils by AID deaminase) and strand nicking plus

Water Bridging Dynamics of Polymerase Chain Reaction in the Gauge Theory Paradigm of Quantum Fields [PDF]

open access: yesWater 2017, 9, 339, 2018
We discuss the role of water bridging the DNA-enzyme interaction by resorting to recent results showing that London dispersion forces between delocalized electrons of base pairs of DNA are responsible for the formation of dipole modes that can be recognized by \textit{Taq} polymerase.

Development of a Decellularized Urinary Bladder Matrix and Heparin‐Based Cryogel for Promoting Angiogenesis

open access: yesMacromolecular Bioscience, EarlyView.
A dECM‐based cryogel scaffold with sustained VEGF release is developed to promote angiogenesis in ischemic tissues. Fabricated from decellularized porcine urinary bladder matrix and heparin, the scaffold supports VEGF binding and prolonged release. The cryogel demonstrates enhanced angiogenic potential in vitro and in a murine hindlimb ischemia model ...

A two stage model for quantitative PCR [PDF]

open access: yesarXiv, 2006
PCR (Polymerase Chain Reaction), a method which replicates a selected sequence of DNA, has revolutionized the study of genomic material, but mathematical study of the process has been limited to simple deterministic models or descriptions relying on stochastic processes.
