No current non-invasive method is capable of assessing the efficacy of brain tumor therapy early during treatment. We outline an approach that evaluates tumor activity via statistical analysis of vessel shape using vessels segmented from MRA. This report is the first to describe the changes in vessel shape that occur during treatment of metastatic brain tumors as assessed by sequential MRA. In this preliminary study of 16 patients undergoing treatment for metastatic breast cancer we conclude that vessel shape may predict tumor response several months in advance of traditional methods.

Cellular distribution of some intermediate filaments in the rat mammary gland during pregnancy, lactation and involution.

Pol J Vet Sci

Department of Histology and Embryology, Faculty of Veterinary Medicine, University of Dicle, 21280 Diyarbakır, Turkey.

Intermediate filaments (IFs) play a major role in determining and maintaining cell shape and anchoring intracellular organelles in place, in the tissues and organs of several species, starting from the early stages of development. This study was aimed at the immunohistochemical investigation of the presence, cellular localization and temporal distribution of the intermediate filaments keratin 8 (CK8), keratin 18 (CK18), keratin 19 (CK19), vimentin, desmin and laminin, all of which contribute to the formation of the cytoskeleton in the rat mammary gland during pregnancy, lactation and involution. On days 7, 14 and 21 of pregnancy (pregnancy period), on day 7 post-delivery (lactation period) and on day 7 post-weaning (involution period), under ketamine hydrochloride (Ketalar-Pfizer) (90 mg/kg) anesthesia, two mammary glands were fully excised from the abdominal region.

In addition to the usual loads, fixed jacket offshore platforms can be exposed to accidental loads from ship collisions. Indentation of tubular components is a significant defect that occurs when a supply vessel collides with a jacket platform, which can affect the ultimate strength of the offshore platform. This paper performs a nonlinear dynamic analysis using ABAQUS software to evaluate the ultimate strength of a wellhead jacket platform and to investigate its structural response to two consecutive impacts from a 2700-ton ship.

Background Topical steroid-dependent or damaged face (TSDF) is a common condition where the widespread availability of over-the-counter topical corticosteroid (TCS)-containing products leads to their misuse and addiction. Prolonged use of these steroids on the face can result in significant side effects. Early diagnosis and cessation of steroid use are important.

Sex-Based Differences of Thoracic Endovascular Aortic Repair for Stanford Type B Aortic Dissections.

Ann Vasc Surg

December 2024

Department of Surgery, Division of Vascular & Endovascular Surgery, UC San Diego, La Jolla, CA; Center for Learning and Excellence in Vascular and Endovascular Research, UC San Diego, La Jolla, CA. Electronic address:

Objective: There is a paucity of data on sex-based differences in outcomes after thoracic endovascular aortic repair (TEVAR) performed for Stanford type B aortic dissections (TBAD). Examining the predictive role of sex could shape future clinical guidelines for TEVAR. Thus, this study aims to evaluate the association between sex and postoperative outcomes after TEVAR performed for TBAD.

 - a large-scale dataset of 3D medical shapes for computer vision.

Biomed Tech (Berl)

December 2024

Institute for Artificial Intelligence in Medicine (IKIM), University Hospital Essen (AöR), Essen, Germany.

Objectives: The shape is commonly used to describe the objects. State-of-the-art algorithms in medical imaging are predominantly diverging from computer vision, where voxel grids, meshes, point clouds, and implicit surface models are used. This is seen from the growing popularity of ShapeNet (51,300 models) and Princeton ModelNet (127,915 models).
