MRI Features of Multiple Cranial Neuropathies in Guillain-Barré Syndrome Occurring after COVID-19 Vaccination: A Case Report.

Guillain-Barré syndrome (GBS) is an immune-mediated demyelinating polyneuropathy characterized by progressive, ascending, and symmetrical paralysis. It is known to be triggered by an antecedent infection or vaccination. Recently, GBS development following coronavirus disease 2019 (COVID-19) vaccination has been reported.

Large Dolichoectasia Concurrently Involving Both Anterior and Posterior Cerebral Circulation: A Case Report.

Dolichoectasia is an uncommon disorder characterized by the presence of a dilated, elongated, and tortuous cerebral artery. Its main pathologic mechanism is the disruption of the internal elastic lamina. Risk factors for dolichoectasia are advanced age, chronic hypertension, and metabolic disease.

[Brain MRI Findings of the Cri-Du-Chat Syndrome: A Case Report and Summary].

Cri-du-chat syndrome is a rare genetic disorder in which the patient presents with a characteristic high-pitched monotonous cry and recurrent aspiration pneumonia, attributed to abnormalities in the larynx, epiglottis, and nervous system. The most prominent brain MRI findings are the presence of pontine and cerebellar hypoplasia, which primarily involve posterior cranial fossa structures. Although atrophy of supratentorial structures were also a common radiological finding, it was considered to be a secondary change due to pontine hypoplasia.

[Delayed Post-Hypoxic Leukoencephalopathy Induced by an Overdose with Fentanyl Patches: A Case Report].

Fentanyl intoxication has occasionally been reported since fentanyl patches became available for medical use. Delayed post-hypoxic leukoencephalopathy is a complication of hypoxia. However, its neuropsychiatric symptoms can be delayed, and it can progress to leukoencephalopathy even after full recovery from coma due to acute intoxication.

Imaging features of primary peritoneal serous carcinoma: A case report.

Primary peritoneal serous carcinoma (PPSC) is an epithelial tumor that arises from the peritoneum. On histopathologic analysis, it resembles a malignant ovarian surface epithelial stromal tumor. A 62-year-old woman visited the emergency room with low abdominal pain.

Evaluation of antioxidant, antinociceptive, and anti-inflammatory activities of ethanol extracts from Aloe saponaria Haw.

Aloe species are traditionally prescribed for hypertension, burning, and rheumatoid arthritis. To elucidate the mechanism of the antihypertensive and anti-inflammatory activities of this herb, the ethanol fraction from A. saponaria Haw.

Preparation of piperazine derivatives as 5-HT7 receptor antagonists.

Twenty-four compounds of 4-methoxy-N-[3-(4-substituted phenyl-piperazine-1-yl)propyl] benzene sulfonamides and N-[3-(4-substituted phenyl-piperazine-1-yl)propyl] naphthyl sulfonamides were prepared and evaluated as 5-HT(7) receptor antagonists. Most of the compounds showed the IC(50) values of 12-580nM. Four methyl branched analogues were also obtained, but the activity for methyl branched analogues was almost same as its straight chain congeners.

Determination of cholesterol in human hair using gas chromatography-mass spectrometry.

This work describes a sensitive method for determining cholesterol in human hair using GC-MS. In this study, we used a very small amount of hair, only 1 mg, to quantify cholesterol. We also can achieve more effective purification and a good recovery over 92% with solid-phase extraction using an Oasis HLB cartridge.
