Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

Molecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

A Multiproject Chip Approach to the Teaching of Analog MOS LSI and VLSI [PDF]

, 1981
Multiproject chip implementation has been used in teaching analog MOS circuit design. After having worked with computer simulation and layout aids in homework problems, students designed novel circuits including several high performance op amps, an A/D ...

Inhibition of CDK9 enhances AML cell death induced by combined venetoclax and azacitidine

Molecular Oncology, EarlyView.
The CDK9 inhibitor AZD4573 downregulates c‐MYC and MCL‐1 to induce death of cytarabine (AraC)‐resistant AML cells. This enhances VEN + AZA‐induced cell death significantly more than any combination of two of the three drugs in AraC‐resistant AML cells.

Fully-Differential Multifunctional Electronically Configurable Fractional-Order Filter with Electronically Adjustable Parameters

Elektronika ir Elektrotechnika, 2018
The paper presents a novel solution of a fully-differential 1+α fractional-order filter. The filter can provide low-pass, high-pass, band-pass and band-stop transfer functions without a necessity of a circuitry change (filter is electronically ...

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Desigin of Synthetic Elements with Transimpedance Operational Amplifiers

Advances in Electrical and Electronic Engineering, 2006
One way how to design active filters for wider frequency band is application of transimpedance operational amplifiers (TOAs) based on current mode. For this aim the TOAs exhibit the most suitable properties: large bandwidth, highslew rate, good linearity,
