Bioengineered Pancreatic Cancer Immunosuppressive Microenvironment Models for Screening Immunotherapies

Advanced Healthcare Materials, EarlyView.
Bioengineering tumor‐stroma pancreatic cancer models with potential to emulate the native immunosuppressive tumor microenvironment. Cancer‐on‐a‐bead models exhibited higher relevance for screening immunotherapies and modulating the protumoral PDAC microenvironment. ABSTRACT Pancreatic cancer is notably resistant to treatment, primarily due to its dense

The relation between parameter curves and lines of curvature on canal surfaces

Kuwait Journal of Science, 2017
A canal surface is the envelope of a moving sphere with varying radius, defined by the trajectory C(t) (spine curve) of its center and a radius function r(t).

Shaping ability of NiTi reciprocating file systems R-motion and waveOne gold in mesial canals of mandibular molars; micro CT study

Scientific Reports
The preservation of the original configurations of root canals during endodontic preparation is crucial for treatment success. Nickel-titanium (NiTi) rotary systems have been refined to optimize canal shaping while minimizing iatrogenic errors.

Design and analysis of a canal section for minimum water loss

Alexandria Engineering Journal, 2011
Seepage and evaporation are the most serious forms of water loss in an irrigation canal network. Seepage loss depends on the channel geometry, while evaporation loss is proportional to the area of free surface.
