Neurovascular Contacts in the Pathophysiology of Neuralgic Amyotrophy: An Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuralgic amyotrophy (NA) is a prevalent, monophasic, multifocal immune‐mediated neuropathy. A distinctive characteristic of the disease is the occurrence of nerve or fascicle constrictions and torsions (NA‐associated focal nerve lesions, NAFL). The pathophysiology underlying this phenomenon remains to be fully elucidated.

Re‐Purposing Sapropterin (Kuvan) for ACTA2‐Related Multisystemic Smooth Muscle Dysfunction Syndrome: A Translational Mechanistic and First‐In‐Human Therapeutic Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Multisystemic smooth muscle dysfunction syndrome (MSMDS) is an ultra‐rare, ACTA2‐related disorder characterized by severe cerebrovascular disease, aortic aneurysms, and smooth muscle dysfunction. Using molecular dynamics simulations and in silico drug screening, we identified that sapropterin dihydrochloride (Kuvan) is a candidate capable of ...

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

Arthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Doppler Ultrasonography and Contrast-Enhanced Ultrasonography

Choonpa Igaku, 2006
胆道疾患に対する超音波カラー・パワードプラ法と造影超音波に関する最近の知験をレビューした. 超音波カラー・パワードプラ法は脈管と胆管の鑑別に有用であり, これは閉塞性黄疸時における経皮経肝的胆道ドレナージを安全に施行するために有用である. 一方, 胆嚢内腫瘤の鑑別にも超音波カラー・パワードプラ法は有用であり, 胆嚢癌では腫瘍血管および胆嚢動脈の最高流速が上昇する. 胆嚢癌のhigh risk groupである膵胆管合流異常は, 胆嚢壁の動脈流速が上昇するといわれ, カラードプラ法が診断の契機となる. 胆嚢ポリープの鑑別においては, 胆嚢癌は造影超音波で樹枝状の血管構築を呈することが多い点が他のポリープとの鑑別点になる.

98: DOPPLER ULTRASONOGRAPHY [PDF]

Pediatric Research, 1988
Prediction by cerebral artery Doppler ultrasonography of neurological outcome in 20 term infants with hypoxic-ischemic encephalopathy (HIE) after perinatal asphyxia and in 20 normal babies (control group) was evaluated. The infants with HIE were divided in 3 groups, grated I to III, according to Sarnat's classification.
