Thalamic hemorrhage due to ruptured aneurysm at the feeder of a tentorial dural arteriovenous fistula in the Galen region mimicking a hypertensive hemorrhage.

Introduction: Thalamic hemorrhage caused by cerebrovascular disease is unusual. We describe a rare case of thalamic hemorrhage due to rupture of an aneurysm at the feeder of a tentorial dural arteriovenous fistula in the Galen region mimicking a hypertensive hemorrhage.

Case Presentation: A 78-year-old woman with sudden-onset right hemiparesis was diagnosed with left thalamic hemorrhage.

Long-term outcomes of the first prospective study of active surveillance for prostate cancer in Japan.

Background: Active surveillance for prostate cancer was initiated in the early 2000s. We assessed the long-term outcomes of active surveillance in Japan.

Methods: This multicenter prospective observational cohort study enrolled men aged 50-80 years with stage cT1cN0M0 prostate cancer in 2002 and 2003.

Outcomes of active surveillance for Japanese patients with prostate cancer (PRIAS-JAPAN).

Objective: To report the outcomes of repeat biopsies, metastasis and survival in the Prostate Cancer Research International: Active Surveillance (PRIAS)-JAPAN study, a prospective observational study for Japanese patients, initiated in 2010.

Patients And Methods: At the beginning, inclusion criteria were initially low-risk patients, prostate-specific antigen (PSA) density (PSAD) <0.2, and ≤2 positive biopsy cores.

Two Cases of Mechanical Thrombectomy in Patients with Fenestration of the M1 Segment of the Middle Cerebral Artery.

M1 fenestration of the middle cerebral artery is rare. We present two patterns of acute thromboembolic conditions in M1 fenestrations treated with mechanical thrombectomy. Case 1 was a male in his 60s presenting with right hemiparesis and aphasia.

Chemically Recyclable Unnatural (1→6)-Polysaccharides from Cellulose-Derived Levoglucosenone and Dihydrolevoglucosenone.

Unnatural polysaccharide analogs and their biological activities and material properties have attracted considerable research interest. However, these efforts often encounter challenges, especially those related to synthetic complexity and scalability. Here, we report the chemical synthesis of unnatural (1→6)-polysaccharides using levoglucosenone (LGO) and dihydrolevoglucosenone (Cyrene), which are derived from cellulose.
