Stability of Zr-Based UiO-66 Metal-Organic Frameworks in Basic Solutions.

Although Zr-based metal-organic frameworks (MOFs) exhibit robust chemical and physical stability in the presence of moisture and acidic conditions, their susceptibility to nucleophilic attacks from bases poses a critical challenge to their overall stability. Herein, we systematically investigate the stability of Zr-based UiO-66 (UiO = University of Oslo) MOFs in basic solutions. The impact of 11 standard bases, including inorganic salts and organic bases, on the stability of these MOFs is examined.

Posterior reversible encephalopathy syndrome following uneventful clipping of an unruptured intracranial aneurysm: A case report.

Background: Posterior reversible encephalopathy syndrome (PRES) is characterized mainly by occipital and parietal lobe involvement, which can be reversible within a few days. Herein, we report a rare case of PRES that developed after craniotomy for an unruptured intracranial aneurysm (UIA).

Case Summary: A 59-year-old man underwent clipping surgery for the treatment of UIA arising from the left middle cerebral artery.

Globus pallidus interna deep brain stimulation for chorea-acanthocytosis.

Chorea-acanthocytosis (ChAc) is a rare hereditary disorder characterized by involuntary choreiform movements and erythrocytic acanthocytosis. Pharmacotherapy for control of involuntary movements has generally been of limited benefit. Deep brain stimulation (DBS) has recently been used for treatment of some refractory cases of ChAc.

Corneal epithelial cellular dysfunction from benzalkonium chloride (BAC) in vitro.

Purpose: To investigate the functional and morphological toxicity of benzalkonium chloride (BAC) on corneal epithelial cells in vitro.

Methods: Primary corneal epithelial cells were cultured from rabbit cornea. Corneal epithelial cells containing radioactive 51Cr were exposed for 5 min, 10 min, 30 min and 60 min to concentration of BAC 0.
