Test-retest reliability of structural brain networks from diffusion MRI [PDF]

open access: yes, 2014
Structural brain networks constructed from diffusion MRI (dMRI) and tractography have been demonstrated in healthy volunteers and more recently in various disorders affecting brain connectivity.

Posterior Lamellar Graft Preparation: A Prospective Review from an Eye Bank on Current and Future Aspects

open access: yesJournal of Ophthalmology, 2013
Descemet membrane endothelial keratoplasty (DMEK) is a corneal surgical technique which selectively replaces the damaged posterior part of the cornea with a healthy donor graft retaining the rest of the tissue intact.

Transgender Corneal Donors: A Dilemma Worthy of Attention

open access: yesOphthalmology and Therapy, 2018
Currently, there are no specific guidelines in place to direct eye banks on how to deal with donated tissue from transgender individuals. This commentary will examine the history of corneal transplantation and the importance of the corneal tissue donor ...

A study to examine the operation and function of a virtual UK environmental specimen bank (UK-ESB). Final report [PDF]

open access: yes, 2012
Executive Summary: 1. Environmental specimen banking is recognised internationally as an integral part of long-term environmental research and monitoring. Analysis of preserved environmental samples is often needed to detect and quantify patterns and

Postoperative detection of unusual pathology in donor corneal tissue

open access: yesIndian Journal of Ophthalmology, 2019
We present a series of three patients with previously undetected corneal pathology in grafted corneal tissue following keratoplasty for keratoconus. Postoperatively, a faint layer of anterior stromal haze involving the graft was observed in each patient ...

Influence of submerged macrophytes on phosphorus in a eutrophic reservoir in a semiarid region

open access: yesJournal of Limnology, 2020
Phosphorus (P) is the main nutrient responsible for the harmful effects caused by the enrichment of aquatic systems, and submerged macrophytes play an important role in this process, since they can both remove and release this nutrient in environmental ...

Role of heterogeneity in dictating tumorigenesis in epithelial tissues [PDF]

open access: yesarXiv, 2022
Biological systems across various length and time scales are noisy, including tissues. Why are biological tissues inherently chaotic? Does heterogeneity play a role in determining the physiology and pathology of tissues? How do physical and biochemical heterogeneity crosstalk to dictate tissue function?

Systemic Losses Due to Counter Party Risk in a Stylized Banking System [PDF]

open access: yes, 2014
We report a study of a stylized banking cascade model investigating systemic risk caused by counter party failure using liabilities and assets to define banks' balance sheet. In our stylized system, banks can be in two states: normally operating or distressed and the state of a bank changes from normally operating to distressed whenever its liabilities
