Novel Use of a Catheter-Based Device Retrieval System for Percutaneous Treatment of Recurrent Atrial Myxoma.

Surgical resection is standard of care for the treatment of atrial myxoma. However, the optimal management strategy for recurrent cardiac tumors is less clear. Here we report the novel use of a catheter-based device retrieval system for the removal of a recurrent cardiac myxoma.

Imaging features and management of tuberculomas: a review of cases and literature.

Aims: To describe the imaging features of patients presenting with soft tissue masses and a provisional diagnosis of soft tissue tumours, for whom biopsy confirmed the presence of necrotising granulomata consistent with tuberculoma.

Material And Methods: A review of the histopathology database for patients who had a diagnosis of necrotising granulomata in nonspinal sites. Patients with bone and joint-based pathology were excluded.

Brain-derived tau oligomer polymorphs: distinct aggregations, stability profiles, and biological activities.

Aggregation of microtubule-associated tau protein is a distinct hallmark of several neurodegenerative disorders such as Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and progressive supranuclear palsy (PSP). Tau oligomers are suggested to be the primary neurotoxic species that initiate aggregation and propagate prion-like structures. Furthermore, different diseases are shown to have distinct structural characteristics of aggregated tau, denoted as polymorphs.

Blarcamesine for the treatment of Early Alzheimer's Disease: Results from the ANAVEX2-73-AD-004 Phase IIB/III trial.

Background: There are no approved oral disease-modifying treatments for Alzheimer's disease (AD).

Objectives: The objective of this study was to assess efficacy and safety of blarcamesine (ANAVEX®2-73), an orally available small-molecule activator of the sigma-1 receptor (SIGMAR1) in early AD through restoration of cellular homeostasis including autophagy enhancement.

Design: ANAVEX2-73-AD-004 was a randomized, double-blind, placebo-controlled, 48-week Phase IIb/III trial.

Facile Synthesis of Oxazolidinones as Potential Antibacterial Agents.

An efficient microwave-assisted synthesis route for novel oxazolidinone analogues has been developed. The general synthesis of these compounds began with an L-proline-mediated three-component Mannich reaction between commercially available 3-fluoro-4-morpholinoaniline, aqueous formaldehyde and α-hydroxyacetone. This was followed by a one-step cyclisation to form the core structure of oxazolidinone antibiotics which was subsequently derivatized.
