Outer Retinal Tubulation in Geographic Atrophy.

Background And Objective: Outer retinal tubulation (ORT) is observed on optical coherence tomography images from patients with geographic atrophy (GA), but its clinical implications are unclear. The objective of this study was to investigate the prevalence of ORT and its association with GA lesion growth rates.

Materials And Methods: This post hoc longitudinal analysis assessed 62 eyes randomized to sham treatment in the phase 2 FILLY trial.

Loss of TXNIP enhances peritoneal metastasis and can be abrogated by dual TORC1/2 inhibition.

Peritoneal metastasis (PM) is a debilitating consequence of multiple cancers. As cancer cells lose tonic signaling related to attachment dependence, critical morphologic shifts result in alteration of the transcriptome. Identifying key genes associated with this transformation may lead to targeted therapies for this devastating complication.

The large graph limit of a stochastic epidemic model on a dynamic multilayer network.

We consider a Markovian SIR-type (Susceptible → Infected → Recovered) stochastic epidemic process with multiple modes of transmission on a contact network. The network is given by a random graph following a multilayer configuration model where edges in different layers correspond to potentially infectious contacts of different types. We assume that the graph structure evolves in response to the epidemic via activation or deactivation of edges of infectious nodes.

Network-based analysis of a small Ebola outbreak.

We present a method for estimating epidemic parameters in network-based stochastic epidemic models when the total number of infections is assumed to be small. We illustrate the method by reanalyzing the data from the 2014 Democratic Republic of the Congo (DRC) Ebola outbreak described in Maganga et al. (2014).
