Tandem occlusions, characterized by the simultaneous occurrence of both extracranial and ipsilateral intracranial arterial occlusions, represents a challenging subset of large vessel occlusion (LVO) strokes. Currently, the treatment choice for tandem infarcts involves intravenous thrombolysis (IVT) followed by endovascular thrombectomy (EVT). In current literature, direct head-to-head comparisons between Alteplase and Tenecteplase for IVT in patients with tandem occlusions remain limited.

The imbalance between the overproduction of reactive species and antioxidant mechanisms can result in astrogliosis and oxidative stress associated with neurodegeneration. Based on the described antioxidant activity of naturally occurring flavonoids, this study evaluated the antioxidant mechanisms of the flavonoid naringenin and the senecioic acid ester derivatives in cortical astrocytes. Naringenin and ()-naringenin were purified from , and from them 7,4--disenecioic ester naringenin, ()-7,4--disenecioic ester naringenin, and 7--senecioic ester naringenin were synthesized and tested for antioxidant activity by the free-radical scavenging reaction with DPPH.

Purpose: We aimed to conduct a systematic review and meta-analysis comparing the outcomes of subdermal implants and levonorgestrel intrauterine system (LNG-IUS) in reproductive-aged women.

Methods: In April 2024, we searched Pubmed, Embase and Cochrane trials using the search terms: "etonogestrel", "levonorgestrel" and "randomized controlled trials". We identified 2862 results comparing the LNG-IUS to subdermal implants.
