Filoviruses, mainly consisting of the two genera of and , are enveloped negative-strand RNA viruses that can infect humans to cause severe hemorrhagic fevers and outbreaks with high mortality rates. However, we still do not have effective medicines for treating these diseases. To search for effective drugs, we have identified three marine indole alkaloids that exhibit potent activities against filovirus infection.

One new gliotoxin derivative fumianthrogliotoxin (), one new indoquizoline alkaloid 3-(methyl propionate) indoquizoline (), and three novel indole alkaloids, anthroxyindole (), (±)-asperfumiindole A (), and (±)-asperfumiindole B (), together with 16 known compounds (-), were isolated from the culture of deep-sea derived fungus AF1. Their chemical structures and absolute configurations were determined through the analysis of NMR data in combination with electronic circular dichroism (ECD) calculations and other spectroscopic analyses. Compounds - and - were evaluated for anti-pulmonary fibrosis activity.

Objective: To investigate the predictive value of machine learning-based PET/CT radiomics and clinical risk factors in predicting interim efficacy in patients with follicular lymphoma (FL).
Methods: This study retrospectively analyzed data from 97 patients with FL diagnosed via histopathological examination between July 2012 and November 2023. Lesion segmentation was performed using LIFEx software, and radiomics features were extracted through the uAI Research Portal (uRP) platform, including first-order features, shape features, and texture features.

A 28-year-old woman was diagnosed with high-risk triple-expressor diffuse large B-cell lymphoma (DLBCL) (stage IV, IPI 4, CNS-IPI 5), with lymph node and extranodal involvement. The patient underwent first-line R-CHOP treatment, achieving a partial response with residual mediastinal uptake. A second-line platinum-based therapy with a transplant plan followed, resulting in stable disease; thus, she was considered refractory and started third-line therapy with CAR-T cells, receiving additional chemotherapy as bridging therapy.

Background: Resistant hypertension (RH) is defined as uncontrolled blood pressure (BP) despite treatment with at least three or more antihypertensive agents. Compelling evidence has shown that such a population has a greater risk of cardiovascular events as well as mortality. Although mineralocorticoid receptor antagonists (MRAs) have been shown to be an effective fourth-line treatment for RH, a significant proportion of RH patients do not achieve their blood pressure target.
