Measurement of the Film Thickness, Film Velocity and Entrainment Fraction in a Liquid-Air Annular Flow Using a Conductance Flowmeter [PDF]

open access: yes, 2009
In certain older oil wells in the Middle East, the produced fluid is predominantly natural gas which flows at very high rates (e.g. 50,000 m3 / day ). Smaller quantities of crude oil (e.g. 50m3 / day ) and water (950m3 / day ) are also produced.

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

open access: yesFEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Measurement of Mist to Annular Flow Development in the Discharge of a Compressor [PDF]

open access: yes, 2012
Compressors produce a flow of oil droplets propelled by refrigerant flow while fully developed flow maps predict predominantly annular flow. This discrepancy is rooted in the lack of understanding of flow development.

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

open access: yesFEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

open access: yesFEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...
