Strontium titanate (STO), a cubic perovskite material, has gained recent attention as a supercapacitor active material with its pseudocapacitive energy storage attributed to anion intercalation. However, very few in-depth studies have been conducted to understand the anion storage properties of STO and its metal-doped derivative compounds. In this study, we explored the anion-insertion storage mechanism of Mn-doped strontium titanate (Mn-STO) compared to pristine STO.

Methods: We conducted a retrospective analysis of patients admitted with acute ischaemic stroke from January 2014 to April 2024. The mRS was dichotomised with favourable outcome (0-2) and unfavourable outcome (3-6).
Celiac artery compression syndrome (CACS) is an elusive cause of postprandial abdominal pain, commonly mistaken for conditions such as gall bladder disease. A 36-year-old male presented with postprandial abdominal pain. Imaging studies revealed compression of the celiac artery by the median arcuate ligament and an incidentally detected narrow aortomesenteric angle, indicating superior mesenteric artery (SMA) syndrome.
