Nowadays, many biological data are acquired via images. In this article, we
study the pathological images scanned from 205 patients with lung cancer with
the goal to find out the relationship between the survival time and the spatial
distribution of different types of cells, including lymphocyte, stroma, and
tumor cells. Toward this goal, we model the spatial distribution of different
types of cel... hiện toàn bộ

In this paper we develop a Bayesian analysis to estimate the disease prevalence,
the sensitivity and specificity of three cervical cancer screening tests
(cervical cytology, visual inspection with acetic acid and Hybrid Capture II) in
the presence of a covariate and in the absence of a gold standard. We use
Metropolis-Hastings algorithm to obtain the posterior summaries of interest. The
estimated ... hiện toàn bộ

Circulating biomarkers are of significant interest for cancer detection and
treatment personalization. However, the biophysical processes that determine how
proteins are shed from cancer cells or their microenvironment, diffuse through
tissue, enter blood vasculature, and persist in circulation remain poorly
understood. Since approaches primarily focused on experimental evaluation are
incapable of... hiện toàn bộ
