Early neurovascular changes in the retina in preclinical diabetic retinopathy and its relation with blood glucose

BMC Ophthalmology, 2021
Background To investigate the changes in retinal nerve fiber layer thickness and macular blood flow density during the preclinical stage of diabetic retinopathy and their relationship with blood glucose. Methods In this cross-sectional study, 97 diabetic

Fluids confined in wedges and by edges: From cluster integrals to thermodynamic properties referred to different regions [PDF]

, 2015
Recently, new insights in the relation between the geometry of the vessel that confines a fluid and its thermodynamic properties were traced through the study of cluster integrals for inhomogeneous fluids.

BMPER regulates cardiomyocyte size and vessel density in vivo [PDF]

Cardiovascular Pathology, 2013
BMPER, an orthologue of Drosophila melanogaster Crossveinless-2, is a secreted factor that regulates bone morphogenetic protein activity in endothelial cell precursors and during early cardiomyocyte differentiation. Although previously described in the heart, the role of BMPER in cardiac development and function remain unknown.

2D modeling of electromagnetic waves in cold plasmas [PDF]

, 2014
The consequences of sheath (rectified) electric fields, resulting from the different mobility of electrons and ions as a response to radio frequency (RF) fields, are a concern for RF antenna design as it can cause damage to antenna parts, limiters and ...

Glaucomatous vertical vessel density asymmetry of the temporal raphe detected with optical coherence tomography angiography. [PDF]

, 2020
Changes in retinal vasculature and ocular circulation may play an important role in the glaucoma development and progression. We evaluated the vertical asymmetry across the temporal raphe of the deep retinal layer vessel density, using swept-source ...
