Cerebral Infarction Due to Occlusion of Main Trunk of Middle Cerebral Artery in Patient with Accessory Middle Cerebral Artery.

The existence of an accessory middle cerebral artery (AMCA) usually has no pathological significance. Three patients developed cerebral infarction due to thromboembolic occlusion of the main trunk of the middle cerebral artery (MCA). In these patients, AMCA originating from the anterior cerebral artery was intact, and ran to the lateral side along the main MCA.

Characteristics and Management of Ruptured Aneurysms Originating from the Penetrating Artery of the Distal Middle Cerebral Artery.

We report a rare case of an aneurysm originating from the penetrating artery of the distal middle cerebral artery (MCA). A 76-year-old man without a notable past history presented with sudden-onset severe headache, left hemiparesis, and a decreased level of consciousness. Computed tomography (CT) revealed subarachnoid hemorrhage (SAH) with intracerebral hemorrhage (ICH) in the right temporal lobe extending into the ventricle.

Hemifacial spasm caused by vertebral artery aneurysm treated by endovascular coil embolization.

Background: Hemifacial spasm (HFS) caused by vertebral artery (VA) aneurysms is rare. Several cases of HFS caused by VA aneurysms treated by endovascular parent artery occlusion (PAO) have been reported. Recently, we treated a rare case of HFS caused by a saccular VA aneurysm at the bifurcation of the posterior inferior cerebellar artery (PICA), which was successfully treated by endovascular coil embolization, preserving the parent artery, and PICA.

Production of bioactive oligopeptide hydrolyzed by protease derived from aerial microalga Vischeria helvetica.

This study focused on a culture system of aerial microalgae with the decomposition of casein protein for obtaining bioactive compounds such as peptides with inhibitory activity against angiotensin-converting enzyme (ACE). The aerial microalga Vischeria helvetica exhibited growth in Bold's basal medium supplemented with casein protein as nitrogen source. The algal cells secreted protease and amino oxidase into the medium, and ammonium ions as a nitrogen source was produced by the conjugated-enzyme reaction.

Development of a whole-cell-based screening method for a carotenoid assay using aerial microalgae.

Non-destructive approaches based on the application of optical spectroscopy are important for monitoring carotenoid accumulation in a whole cell cultured under various conditions. A simple and rapid assay utilizing aerial microalgae helps to identify stress conditions that can efficiently enhance the carotenogenesis in photosynthetic organisms. The spectra of cell suspensions were characterized in the aerial microalga Coelastrella sp.

Metabolic switching: synergistic induction of carotenogenesis in the aerial microalga, Vischeria helvetica, under environmental stress conditions by inhibitors of fatty acid biosynthesis.

Objectives: To investigate the roles of fatty acid biosynthesis in carotenogenesis in the high-lipid accumulating aerial microalga Vischeria helvetica KGU-Y001, we cultured algal cells with fatty acid biosynthesis inhibitors.

Results: Under nitrogen-deficient, high-light (200 µmol photons m(-2) s(-1)) conditions, the alga accumulated 6.2 mg carotenoids g(-1) dry weight cells (DWC) after 1 week of culture.

Fatty acid content and profile of the aerial microalga Coccomyxa sp. isolated from dry environments.

Aerial algae are considered to be highly tolerant of and adaptable to severe conditions including radiation, desiccation, high temperatures, and nutrient deficiency, compared with those from aquatic habitats. There are considerable variations in the fatty acid (FA) composition of aerial microalgae from dry environments. A new species with a high lipid level was found on concrete surfaces and was identified as Coccomyxa sp.

Characteristics of chlorophyll formation of the aerial microalga Coelastrella striolata var. multistriata and its application for environmental biomonitoring.

The growth and ammonium uptake of the aerial microalga Coelastrella striolata var. multistriata, which was isolated from the surface of rocks, were characterized in this study. The specific growth rate of the alga was mu=0.
