Seamless Iterative Semi-Supervised Correction of Imperfect Labels in Microscopy Images [PDF]

arXiv, 2022
In-vitro tests are an alternative to animal testing for the toxicity of medical devices. Detecting cells as a first step, a cell expert evaluates the growth of cells according to cytotoxicity grade under the microscope. Thus, human fatigue plays a role in error making, making the use of deep learning appealing.

Mathematical analysis and simulation study of a phase-field model of prostate cancer growth with chemotherapy and antiangiogenic therapy effects [PDF]

arXiv, 2019
Cytotoxic chemotherapy is a common treatment for advanced prostate cancer. These tumors are also known to rely on angiogenesis, i.e., the growth of local microvasculature via chemical signaling produced by the tumor. Thus, several clinical studies have been investigating antiangiogenic therapy for advanced prostate cancer, either as monotherapy or ...

Gap Junctions: The Claymore for Cancerous Cells [PDF]

BioImpacts, 2011, 1(2), 113-119, 2011
Introduction: Gap junctions play an important role in the cell proliferation in mammalian cells as well as carcinogenesis. However, there are controversial issues about their role in cancer pathogenesis. This study was designed to evaluate genotoxicity and cytotoxicity of Carbenoxolone (CBX) as a prototype of inter-cellular gap junction blocker in MCF7

Cytoxicity and cytostatic drug removal in a membrane bioreactor from wastewater [PDF]

, 2009
The growing use of antineoplastic drugs in cancer therapy is an emerging issue in environmental research. The presence of the anticancer drug cyclophosphamide (CP) in municipal wastewater raises several environmental problems.

Chloroquine-enhanced gene delivery mediated by carbon nanotubes [PDF]

, 2011
Polyethyleneimine-coated double-walled carbon nanotubes (DWCNTs) were used for dual gene and drug delivery, after loading the DWCNTs with the drug chloroquine, a lysosomotropic compound that is able to promote escape from the lysosomal compartment ...

Computational Inference Methods for HIV-1 Selective Sweeps Shaped by Early Cytotoxic T-Lymphocyte Response [PDF]

arXiv, 2012
In this work we develop a stochastic model of acute HIV infection, based on the well-known standard model, that allows us to simulate the complex mutation pathways of HIV escape from multiple CTL responses. Under this model, we describe two computational inference methods. In one, we use a Bayesian approach to construct posteriors for the parameters of
