Importance: Recent evidence indicates the efficacy of β-amyloid immunotherapy for the treatment of Alzheimer disease, highlighting the need to promote β-amyloid removal from the brain. Cilostazol, a selective type 3 phosphodiesterase inhibitor, promotes such clearance by facilitating intramural periarterial drainage.
Objective: To determine the safety and efficacy of cilostazol in mild cognitive impairment.

We herein report the case of a 45-year-old woman who developed a continuous hemicranial headache subsequent to vertebral artery dissection (VAD). After remission of VAD, the patient repeatedly experienced right forehead and temporal region throbbing headache, accompanied by nausea, ocular hyperemia and lacrimation of the right eye, nasal congestion, and rhinorrhea. Magnetic resonance angiography did not reveal the recurrence of dissection.

The aim of the current investigation is (1) to evaluate the accuracy of calibration (k factor determinations and absorption corrections using a combination of differential X-ray absorption (DXA) and convergent beam electron diffraction (CBED)) by comparing with thermodynamic calculations and (2) to demonstrate the importance of the EDX chemical analysis by taking advantage of its unique capabilities to analyse sub-micron scale chemistries within a mesoscopic field of view under STEM. Our experimental findings show good agreement with the mole fraction ratio of γ' to the disordered γ matrix predicted using the Lever rule on a thermodynamically stabilised unimodal superalloy, RR1000.

Cerebral air embolism (CAE) is a rare cause of stroke. Most cerebral air emboli are caused by iatrogenic factors, such as invasive cardiac and pulmonary procedures. Here, we report an unusual case of CAE not related to any medical intervention.

Carbon quantification and the standardisation in a pure cementite were conducted using pulsed-laser atom probe tomography (APT). The results were analysed to investigate a dependence on three distinct experimental parameters; the laser pulse energy, the cryogenic specimen temperature and the laser pulse frequency. All the measurements returned an apparent carbon content of 25.

The prognosis of the disease in recent years has been improved because chemotherapy is performed before hepatectomy to reduce tumor size (conversion therapy). The purpose of this study was to investigate the safety and efficacy of conversion therapy following HAI immunochemotherapy.

The apparatus consists of a (Bi,Pb)(2)Sr(2)Ca(2)Cu(3)O(10) (Bi-2223) superconducting magnet, an outer dewar, and a variable temperature insert (VTI). The magnet, which is operated in depressurized liquid nitrogen, generates magnetic field up to 1.

The original article describing this condition demonstrated that patients with spinocerebellar ataxia 36 present with tongue atrophy, a finding that had not been seen in previous types of spinocerebellar ataxias. A total of 2121 patients with clinically diagnosed spinocerebellar ataxia participated in the study.

On the night of admission to our hospital, he showed disorientation to places and abnormal eating behavior, indicating a complication of MRSA meningitis. Cerebrospinal fluid (CSF) examination confirmed this diagnosis.

This patient underwent hepatic arterial infusion chemotherapy after low anterior resection for rectal cancer. Hepatic arterial infusion was discontinued due to severe diarrhea, and the administration of UFT (300 mg/day) and LV(75 mg/day) was then begun.

We have examined whether chronic cerebral hypoperfusion accelerates amyloid beta deposition in amyloid protein precursor transgenic (APP-Tg) mouse. At 5, 8, and 11 months of age, C57Bl/6J male mice overexpressing a mutant form of the human APP bearing the both Swedish (K670N/M671L) and the Indiana (V717F) mutations (APPSwInd) and their litterrmates were subjected to either sham operation or bilateral carotid artery stenosis (BCAS) using microcoils with an internal diameter of 0.

In this system, the sample solution is circulated in the route formed by an access path in a split superconducting magnet to maintain a constant protein concentration during the titration experiments. A concentration-control procedure for the ligand/protein ratio is devised, and the ligand/protein ratio is well controlled by this apparatus.

When coculturing endothelial cells and labeled monocytes/macrophages (Mo/Phi) that were collected from peripheral blood and allowed to engulf fluorescent latex beads, some Mo/Phi changed their shapes and became epithelioid cells that were indistinguishable from vascular endothelial cells. This transformation started within several hours of coculturing.

Therefore, we compared the capillary beds in AD and BD brains, using a modified Gallyas silver impregnation method and immunohistochemistry for beta amyloid. Eight autopsied brains with AD and seven with BD were compared with six control brains.

Arundic acid, a novel astroglia-modulating agent, is neuroprotective in acute cerebral infarction, whereas the protective effects remain unknown during chronic cerebral hypoperfusion. Rats undergoing chronic cerebral hypoperfusion were subjected to a bilateral ligation of the common carotid arteries, and were allowed to survive for 3, 7 and 14 days.
View Article and Find Full Text PDFA hydrogen bond formed between the superoxide anion and the ammonium ion (NH4+) accelerates electron transfer from the C60 radical anion to oxygen significantly, whereas the tetra-n-butylammonium ion has no ability to form a hydrogen bond with the superoxidie anion, exhibiting no acceleration of the electron-transfer reduction of oxygen. The second-order rate constant of electron transfer from C60*- to O2 increases linearly with increasing concentration of NH4+. This indicates that O2*- produced in the electron transfer from C60 to O2 is stabilized by 1:1 complex formation between O2*- and NH4+.

The k(et) values of linoleic acid with a series of oxidants are the same as the corresponding k(et) values of methyl linoleate, linolenic acid, and arachidonic acid, leading to the same E(ox) value of linoleic acid, methyl linoleate, linolenic acid, and arachidonic acid (1.76 V vs SCE), which is significantly lower than that of oleic acid (2.
