Adaptor protein Abelson interactor 1 in homeostasis and disease.

Cell Commun Signal

October 2024

Division of Hematology/Oncology, Department of Medicine, Warren Alpert Medical School of Brown University and Rhode Island Hospital, Providence, RI, USA.

Dysregulation of Abelson interactor 1 (ABI1) is associated with various states of disease including developmental defects, pathogen infections, and cancer. ABI1 is an adaptor protein predominantly known to regulate actin cytoskeleton organization processes such as those involved in cell adhesion, migration, and shape determination. Linked to cytoskeleton via vasodilator-stimulated phosphoprotein (VASP), Wiskott-Aldrich syndrome protein family (WAVE), and neural-Wiskott-Aldrich syndrome protein (N-WASP)-associated protein complexes, ABI1 coordinates regulation of various cytoplasmic protein signaling complexes dysregulated in disease states.

Purpose: We quantified the morphology and angulation of the third metacarpal (MC3) relative to the capitate using three-dimensional computed tomography data to inform surgical procedures such as total wrist arthroplasty and wrist arthrodesis. Specifically, we report the three-dimensional location of the intersections of the long axis of MC3 axis with the capitate cortical surface, the sagittal and coronal angles between the MC3 and capitate axes, and the MC3 shaft angle in the sagittal plane. We tested the hypothesis that these metrics did not differ between women and men.

Article Synopsis
  • The thumb carpometacarpal (CMC) joint's unique biomechanics, influenced by ligaments like the anterior oblique ligament (AOL) and dorsoradial ligament (DRL), enable its power and precision.
  • This study examined the impact of cutting the AOL or DRL on thumb CMC joint biomechanics, including rotational and translational range-of-motion (ROM) and stiffness, using robotic simulations.
  • Results showed that cutting the DRL increased rotational ROM in flexion and internal rotation, while cutting the AOL improved ROM in extension, indicating that both ligaments provide essential stabilizing functions for the thumb joint.

The passive biomechanics of the thumb carpometacarpal joint: An in vitro study.

J Biomech

May 2024

Center for Biomedical Engineering and School of Engineering, Brown University, Providence, RI 02912, USA; Department of Orthopedics, The Warren Alpert Medical School of Brown University and Rhode Island Hospital, Providence, RI 02903, USA. Electronic address:

Article Synopsis
  • The thumb carpometacarpal (CMC) joint allows complex movements of the thumb, crucial for gripping and precision tasks, but traditional measurements focused mainly on basic range-of-motion (ROM) in four directions.
  • Researchers developed a method to measure the thumb's multidirectional motion in 6 degrees-of-freedom using a robotic simulation system on 10 specimens, going beyond basic ROM to include stiffness and combining multiple motion directions.
  • The study revealed that thumb CMC joint movement is most flexible and least stiff in oblique directions, with specific coupling patterns during movements, enhancing our understanding of thumb mechanics for better treatment of pathologies.

Imaging and Management of Radial Scars and Complex Sclerosing Lesions.

Radiographics

October 2023

From the Department of Radiology, Boston Medical Center, Boston, Mass (B.Z.M., J.P.); Department of Diagnostic Imaging, Warren Alpert Medical School of Brown University and Rhode Island Hospital, 593 Eddy St, 3rd Floor, Providence, RI 02903 (E.H.D., A.P.L.); and Department of Pathology, Beth Israel Deaconess Medical Center, Boston, Mass (L.M.Q.).

Radial scars and complex sclerosing lesions, often collectively referred to as radial sclerosing lesions (RSLs), are breast lesions characterized by sclerotic stroma with entrapped epithelial elements. RSLs have imaging features that overlap with those of breast malignancy and often become the target of imaging-guided biopsy given their suspicious imaging appearance. These can be identified in isolation or can also be associated with atypia or other high-risk lesions that have intrinsic malignant potential, increasing the risk of carcinoma and affecting prognosis and management of RSLs.

Despite a rise in women being arrested for domestic violence and court-ordered to batterer intervention, batterer interventions remain limited in their ability to address women's treatment needs. Alcohol use is an important intervention target: one-third of women in batterer interventions have an alcohol-related diagnosis, half engage in at-risk drinking, and alcohol use contributes to intimate partner violence (IPV) and batterer intervention dropout. Research has not evaluated whether adding an alcohol intervention to batterer intervention improves women's alcohol use and IPV outcomes.

In animal models, human bone marrow mesenchymal stem cell-derived extracellular vesicles (MSC-EV) have been found to have beneficial effects in cardiovascular disease, but only when administered via intramyocardial injection. The biodistribution of either intravenous or intramyocardial injection of MSC-EV in the presence of myocardial injury is uncharacterized at this time. We hypothesized that intramyocardial injection will ensure delivery of MSC-EV to the ischemic myocardium, while intravenous injection will not.
