Article Synopsis
- To achieve carbon neutrality by 2050, capturing carbon dioxide from the atmosphere is essential, and direct air capture (DAC) using amine-based compounds is being researched for effectiveness.
- Researchers developed thermosetting DAC nanofibers that show strong performance with low-temperature desorption and heat resistance by polymerizing amines with epoxy, using poly(vinyl alcohol) (PVA) for easier fabrication.
- The resulting nanofiber webs demonstrated high CO adsorption capacity and efficient desorption, allowing for sustainable and low-energy recovery of CO while also maintaining stability over prolonged use.
Article Synopsis
- Adult colonic intussusceptions are uncommon and often related to organic lead points, but the exact causes and mechanisms remain unclear.
- A case study of a 74-year-old woman showed retrograde colonic intussusception linked to previous colonoscopies, despite no identifiable lead point found during examination.
- This finding is significant as it is the first reported case of colonoscopy-related retrograde intussusception without visible abnormalities, suggesting new avenues for understanding how this condition can occur.
Introduction: Diabetes mellitus (DM) is known to be a cause of cervical internal carotid artery stenosis (ICS). In this study, we investigated the natural history of asymptomatic ICS in DM patients without surgical intervention.
Methods: We conducted a retrospective study of 148 DM patients with asymptomatic ICS treated medically at the Kansai Electric Power Hospital from April 2013 to March 2023, inclusive.
Article Synopsis
- The study aimed to assess the effectiveness and safety of MR-guided focused ultrasound (MRgFUS) treatment for patients with essential tremor, particularly focusing on those with a low skull density ratio (SDR).
- Real-world data from 101 patients treated between July 2019 and March 2022 were analyzed, categorizing patients into four quartiles based on their mean SDR and evaluating treatment outcomes, parameters, and adverse events.
- Results showed that MRgFUS significantly improved tremor severity across all SDR groups, but individuals with very low SDR experienced lower temperature and coagulation volume during treatment, along with more frequent adverse events, which mostly resolved by the 3-month follow-up.
Background: Twig-like middle cerebral artery (T-MCA) is reported as a rare vascular anomaly characterized by reconstitution of the M1 segment of the middle cerebral artery (MCA) by a plexiform network of small vessels. Although it is generally believed that the etiology of T-MCA is an embryological persistence, some investigators have suggested that T-MCA may be a secondary consequence. Here, the authors report a second case of de novo T-MCA formation and reconsider the concept of T-MCA in connection with isolated MCA disease.
