Background: The effect of temporary blood flow arrest during endovascular thrombectomy for acute ischemic stroke is uncertain due to the lack of evidence from randomized controlled trials. We aimed to investigate whether temporary blood flow arrest during endovascular thrombectomy using a balloon guide catheter improves intracranial vessel recanalization compared with nonflow arrest.
Methods: The ProFATE trial (Proximal Blood Flow Arrest During Endovascular Thrombectomy) was a multicenter, randomized, participant- and outcome-blinded trial at 4 thrombectomy centers in the United Kingdom.
Undifferentiated pleomorphic sarcoma (UPS) is an uncommon and aggressive soft tissue tumor primarily affecting older adults, often presenting as a rapidly enlarging, painless mass in the extremities or other deep-seated locations. This case involves a 55-year-old woman who experienced a rapidly progressive and painful swelling in her right thigh following trauma. Imaging studies identified a large, lobulated tumor in the adductor muscles, close to the femur and pubic ramus, with no bone involvement or evidence of distant metastasis.

Flight costs should increase with rising temperatures because lift decreases as density decreases, whereas weight remains unchanged. The effects of density are well-established in the context of high-altitude movements and migration.

Recent studies suggest that physicochemical properties of materials can dictate pro-regenerative versus pro-fibrotic responses and have begun to define the key immune cell types and signals governing these divergent effects. This emerging understanding enables the engineering of regenerative biomaterials capable of functional restoration in situ.

The present case is an unusual presentation of a phyllodes tumor with pseudoangiomatous stromal hyperplasia (PASH) which forms an essential part of benign breast disease but is not frequently described in association with phyllodes tumor. A 36-year-old female patient was referred to the hospital with a large breast mass considered to be a benign growth.
