Successful Microsurgical Clipping under Extracorporeal Membrane Oxygenation Treatment for a Poor-Grade Subarachnoid Hemorrhage Patient with Severe Pulmonary Neurogenic Lung.

Hemorrhagic strokes are considered as contraindications of extracorporeal membrane oxygenation (ECMO) therapy because of anticoagulant administration and ECMO-associated coagulopathy. We present a rare case of successful microsurgical clipping under ECMO for a poor-grade subarachnoid hemorrhage (SAH) patient with severe neurogenic pulmonary edema (NPE). A 50-year-old man presenting with the sudden loss of consciousness was diagnosed with poor-grade SAH with severe NPE, and was intubated.

Clinical Characteristics and Outcomes of Aneurysmal Subarachnoid Hemorrhage Patients Who Live Alone.

It has been shown that living alone is one of the risk factors for unfavorable outcomes in ischemic stroke patients, mostly due to delay in receiving appropriate treatment. A single-center retrospective observational study was conducted to evaluate whether living alone was associated with unfavorable outcomes in aneurysmal subarachnoid hemorrhage (SAH) patients. Among 451 SAH patients admitted to our institution between January 2013 and December 2022, 43 patients who lived alone had sustained SAH at home (group A) and 329 patients who lived with family had sustained SAH at home (group F).

A rare case of sacral epidural arteriovenous fistula with concomitant occult multiple lumbar epidural arteriovenous fistulas.

We describe a rare case of sacral epidural arteriovenous fistulas (edAVFs) with atypical clinical course of treatment. A 78-year-old man with a history of spinal surgery presented progressive gait disturbance and urinary incontinence. Spinal angiography demonstrated a sacral spinal AVF fed by bilateral lateral sacral arteries, draining to the venous pouch with subdural drainage.

Air-Stable Thin Films with High and Anisotropic Electrical Conductivities Composed of a Carbon-Centered Neutral π-Radical.

Air-stable thin films (50-720 nm thickness) composed of a carbon-centered neutral π-radical with high and anisotropic electrical conductivities were fabricated by vapor deposition of 4,8,12-trioxotriangulene (). The thin films were air-stable over 15 months and were the aggregate of microcrystals, in which a one-dimensional π-stacking column was formed through the strong singly occupied molecular orbital (SOMO)-SOMO interaction with two-electron-multicenter bond among the spin-delocalized π-planes. The orientations of the one-dimensional column of were changed depending on the deposition rate and substrates, where face-on-oriented thin films were epitaxially grown on the graphite 0001 surface, and edge-on-oriented thin films were grown on glass, SiO, and indium tin oxide substrates under a high-deposition rate condition.

[Intracranial inflammatory pseudotumor resected after transcatheter embolization: a case report].

A 63-year-old man presented with an exceptionally rare case of intracranial inflammatory pseudotumor manifesting as speech and gait disturbance. Magnetic resonance imaging showed a left convexity mass with significant peritumoral edema. The mass was attached to the convexity dura and mimicked meningioma.

Ornithine ingestion improved sleep disturbances but was not associated with correction of blood tryptophan ratio in Japanese Antarctica expedition members during summer.

Members of expeditions to Antarctica may show changes in biological and physiological parameters involved in lipid, glucose, and thyroid hormone metabolism as they adapt to the environment; however, alterations in amino acid (AA) levels and sleep among expedition members in Antarctica have yet to be fully elucidated. We hypothesized that there would be alterations of blood AA levels, and ornithine (Orn) ingestion would affect biological parameters and sleep in Japanese expedition members during the summer in Antarctica. Japanese Antarctica Research Expedition members (22 people) who stayed in Antarctica for 3 months from December 2010 were examined, and a randomized double-blind study of Orn ingestion (400 mg/d) for 4 weeks was performed.
