Gray-White Matter Ratio at the Level of the Basal Ganglia as a Predictor of Neurologic Outcomes in Cardiac Arrest Survivors: A Literature Review.

Loss of gray-white matter discrimination is the primary early imaging finding within of cranial computed tomography in cardiac arrest survivors, and this has been also regarded as a novel predictor for evaluating neurologic outcome. As displayed clearly on computed tomography and based on sensitivity to hypoxia, the gray-white matter ratio at basal ganglia (GWR-BG) region was frequently detected to assess the neurologic outcome by several studies. The specificity of GWR-BG is 72.

MicroRNAs and Target Genes in Pituitary Adenomas.

Pituitary adenomas account for the top three primary intracranial tumors in terms of total incidence rates. The clinical symptoms presented by the disease are often characterized by a series of systemic endocrine disorders, severe occupational lesions, and even some malignant features, and therefore early diagnosis and predicting recurrence would be instructive for clinical treatment of pituitary adenomas. An increasing number of specific microRNA (miRNA) expression signatures have been identified in pituitary, and miRNAs are related with the pituitary tumorigenesis, dysfunction, neurodegeneration, and metastatic non-functioning pituitary carcinoma.

MicroRNA-524-5p Functions as a Tumor Suppressor in a Human Pituitary Tumor-Derived Cell Line.

Clinical nonfunctional pituitary adenomas (NFAs) account for about 40% of pituitary adenomas with almost no clinically relevant hormonal symptoms. Increasing evidence shows that many microRNAs are involved in the development and progression of pituitary adenomas. MicroRNA-524-5p (miR-524-5p) has been reported to cause characteristic alterations in various tumors.
