Challenges of Soft Tissue Integration Around Dental Implants and Strategies Based on Material Surface Modification

open access: yesAdvanced Materials Interfaces, EarlyView.
Peri‐implant soft tissue integration (STI), weaker than natural teeth, raises peri‐implant disease risk. Gingival‐region material surface properties critically modulate soft‐tissue responses, driving surface modifications to enhance STI. This review provides an in‐depth analysis of the challenges of STI around dental implants, comprehensively reviews ...

Biased Signaling Pathways in β2-Adrenergic Receptor Characterized by 19F-NMR

open access: yesScience, 2012
Choosing a Path The β2-adrenergic receptor (β2AR) is a G protein–coupled receptor that recognizes diverse ligands to trigger signaling in the cell.

Insights into the Dynamics and Binding Mechanisms of the Alkhumra Virus NS2B/NS3 Protease: A Molecular Dynamics Study

open access: yesAdvanced Theory and Simulations, EarlyView.
The ΔRMSF$\Delta {\rm RMSF}$ analysis reveals significant flexibility differences between free NS3 and the NS2B/NS3 complex, with notable deviations in specific regions. Key residues driving NS2B binding are identified, and the protonation state of catalytic serine affects oxyanion hole formation.

Accurate Transcription Factor Activity Inference to Decipher Cell Identity from Single‐Cell Transcriptomic Data with MetaTF

open access: yesAdvanced Science, EarlyView.
MetaTF is a new computational framework that uses single‐cell RNA sequencing (scRNA‐seq) data to infer transcription factor activity with the aim to help in deciphering cells identity starting from a heterogeneous population, and apply it to characterize mouse hematopoietic stem cells and breast cancer epithelial cells, thus identifying a novel subset ...

Postural Orthostatic Tachycardia Syndrome Is Associated With Elevated G‐Protein Coupled Receptor Autoantibodies

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background The etiology of postural orthostatic tachycardia syndrome (POTS) is yet to be established. The disorder is often misdiagnosed as chronic anxiety or a panic disorder because the autonomic failure in these patients is not severe.

Beta 1- and beta 2-adrenergic-receptor subpopulations in nonfailing and failing human ventricular myocardium: coupling of both receptor subtypes to muscle contraction and selective beta 1-receptor down-regulation in heart failure.

open access: yesCirculation Research, 1986
We used radioligand binding techniques and measurement of beta-agonist-mediated positive inotropic responses in isolated cardiac tissue to examine beta-adrenergic-receptor subpopulations in nonfailing and failing human left and right ventricular ...

Exercise without Weight Loss Prevents Seasonal Decline in Vitamin D Metabolites: The VitaDEx Randomized Controlled Trial

open access: yesAdvanced Science, EarlyView.
In people with overweight or obesity, regular exercise even without weight loss or vitamin D supplementation completely prevents the usual winter decline in the vitamin D metabolite that maintains health at a cellular level, 1,25(OH)2D3, and ameliorates the decline in the vitamin D status marker 25(OH)D.

Increased accuracy of ligand sensing by receptor diffusion on cell surface [PDF]

open access: yesPhysical Review E 82, 041902 (2010), 2010
The physical limit with which a cell senses external ligand concentration corresponds to the perfect absorber, where all ligand particles are absorbed and overcounting of same ligand particles does not occur. Here we analyze how the lateral diffusion of receptors on the cell membrane affects the accuracy of sensing ligand concentration.

Cardiomyocyte‐Enriched USP20 Ameliorates Pathological Cardiac Hypertrophy by Targeting STAT3 Deubiquitination

open access: yesAdvanced Science, EarlyView.
Cardiomyocyte‐enriched USP20 regulates the K63‐linked ubiquitination of STAT3, and the cardiomyocyte‐specific USP20‐STAT3‐CARM1 axis exerts a protective role in cardiac hypertrophy. Targeting USP20 through cardiac‐specific gene therapy presents a promising strategy for the treatment of cardiac hypertrophy.

Serum Activity Against G Protein–Coupled Receptors and Severity of Orthostatic Symptoms in Postural Orthostatic Tachycardia Syndrome

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Postural orthostatic tachycardia syndrome (POTS) is characterized by excessive heart rate increase on standing and orthostatic intolerance. Previous data indicate autoimmune involvement.
