Transcatheter Mitral Valve Implantation: TMVI Status in 2024

open access: yesKardiyovasküler Tıp E Dergisi/E Journal of Cardiovascular Medicine
Today, it is almost 22 years since the first transcatheter aortic valve implant (TAVI) and 11 years since the first transcatheter mitral valve implantation (TMVI) was implanted. TMVI never escalated like TAVI. So far, only one transcatheter mitral valve (

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Sizing the aortic annulus.

open access: yesAnnals of cardiothoracic surgery, 2012
Transcatheter aortic valve implantation (TAVI) is a valuable alternative for aortic valve replacement in selected high-risk candidates. Accurate preoperative assessment of the aortic annular dimensions is crucial for the success of TAVI, since choice of an incorrectly sized prosthesis may result in catastrophic complications.

On the annulus conjecture [PDF]

open access: yesProceedings of the American Mathematical Society, 1966
The annulus conjecture states that the closure of the region between two locally flat (n-1)-spheres in Rn is homeomorphic to SnX [-1, 1]. The annulus conjecture is fundamental to geometric topology (see [5, p. 579]); for example its truth in dimensions 6 using the hcobordism theorems of [7] and [6].
