Self-activating air filtration device for aerosol control during luminal instruments drying in the sterile processing department [PDF]

PLoS One
Background Luminal instruments are characterized by their slender internal lumens, which make them particularly challenging to clean and dry. A common drying method used by Sterile Processing Department (SPD) technicians involves blowing high-pressure air into one end of the lumen to expel moisture. However, this process generates a significant amount

Magnetically controlled microrobotic system for programmable stiffness tuning and active steering of microcatheters. [PDF]

Nat Commun
Surgical tasks in small tortuous lumens demand interventional instruments with controllable mechanical adaptability. However, current microcatheters lack a non-disruptive, integration-ready strategy for dynamic stiffness tuning—critical for meeting the ...

Instrumentation of a self-luminous fixation annulus [PDF]

Behavior Research Methods & Instrumentation, 1975
A simple and inexpensive way of constructing a fixation annulus is described. Such a device is important for experiments in which a fixation spot in the test field area is undesirable or when subjects’ experimental tasks preclude their manipulation of a fixation dot brightness control.

A FACS-Free Purification Method to Study Estrogen Signaling, Organoid Formation, and Metabolic Reprogramming in Mammary Epithelial Cells

Frontiers in Endocrinology, 2021
Few in vitro models are used to study mammary epithelial cells (MECs), and most of these do not express the estrogen receptor α (ERα). Primary MECs can be used to overcome this issue, but methods to purify these cells generally require flow cytometry and

The association between plasma chemokines and breast cancer risk and prognosis: A mendelian randomization study

Frontiers in Genetics, 2023
Background: Despite the potential role of several chemokines in the migration of cytotoxic immune cells to prohibit breast cancer cell proliferation, a comprehensive view of chemokines and the risk and prognosis of breast cancer is scarce, and little is ...

Impact of experimental colitis on mitochondrial bioenergetics in intestinal epithelial cells

Scientific Reports, 2022
Intestinal homeostasis is highly dependent on optimal epithelial barrier function and permeability. Intestinal epithelial cells (IEC) regulate these properties acting as cellular gatekeepers by selectively absorbing nutrients and controlling the passage ...
