Mechanisms of Amplified Arteriogenesis in Collateral Artery Segments Exposed to Reversed Flow Direction
Joshua L. Heuslein,Joshua K. Meisner,Xuanyue Li,Ji Song,Helena Vincentelli,Ryan J. Leiphart,Elizabeth G. Ames,Brett R. Blackman,Richard J. Price +8 more
TL;DR: Reversed flow leads to a broad amplification of proarteriogenic endothelial signaling and a sustained intercellular adhesion molecule 1–dependent augmentation of arteriogenesis.

CFD analysis of the human airways under impedance-based boundary conditions: Application to healthy, diseased and stented trachea
TL;DR: The proposed impedance method represents an attractive tool to compute physiological pressure conditions that are not possible to extract in vivo and can be applied to healthy, pre- and post-operatory tracheas showing the possibility of predicting, through numerical simulation, the flow and the pressure field before and after surgery.

The Relationship of Retinal Vessel Geometric Characteristics to the Incidence and Progression of Diabetic Retinopathy.
Ronald Klein,Kristine E. Lee,Lorraine G. Danforth,Michael Y. Tsai,Ronald E. Gangnon,Stacy E. Meuer,Tien Yin Wong,Carol Y. Cheung,Barbara E.K. Klein +8 more
TL;DR: Retinal vessel geometric characteristics of the retinal venules were associated with progression ofDR; however, most of the RVGCs measured from digitized fundus photographs added little to the assessment of risk of incidence and progression of DR when other risk factors were considered in T1DM and T2DM.

An automated self-similarity analysis of the pulmonary tree of the Sprague-Dawley rat.
Daniel R. Einstein,Blazej Neradilak,Nayak Pollisar,Kevin R. Minard,Christopher Wallis,Michelle V. Fanucchi,James P. Carson,Andrew P. Kuprat,Senthil Kabilan,Richard E. Jacob,Richard A. Corley +10 more
TL;DR: It is shown that branches not segments are the fundamental repeating unit in the rat lung and develop simple mathematical relationships describing these structures for the entire lung as well as both a deterministic and stochastic character.

A Microfabricated Phantom for Quantitative MR Perfusion Measurements: Validation of Singular Value Decomposition Deconvolution Method
TL;DR: A perfusion phantom with unique features and a wide variety of applications in magnetic resonance imaging (MRI) and other imaging modalities is presented, using microfabrication technique to create a network of microchannels.
