Evaluation of the Prognosis of Neuroglioma Based on Dynamic Magnetic Resonance Enhancement.

This paper explores the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for the prognosis of glioma, and judges the relevant factors affecting the prognosis of glioma. This paper used a Cox proportional hazards model to retrospectively analyze clinical data of 81 patients with complete neuroglioma from the same neurosurgery medical team from January 2012 to November 2018, including DCE-MRI data. To determine the prognostic factors, P < 0.

MicroRNA-18a regulates invasive meningiomas via hypoxia-inducible factor-1α.

The aim of the present study was to investigate the effects of microRNA-18a (miR-18a) on the invasiveness and metastasis of invasive meningiomas and the underlying mechanism. A total of 69 patients with meningiomas (30 patients in the invasive meningioma group and 39 patients in the non-invasive meningioma group) and 48 cases in the control group were enrolled. Samples of meningioma tissues, serum and cerebrospinal fluid were collected.

Dynamic behaviors of approximately ellipsoidal microbubbles photothermally generated by a graphene oxide-microheater.

Thermal microbubbles generally grow directly from the heater and are spherical to minimize surface tension. We demonstrate a novel type of microbubble indirectly generated from a graphene oxide-microheater. Graphene oxide's photothermal properties allowed for efficient generation of a thermal gradient field on the microscale.

Graphene oxide-deposited microfiber: a new photothermal device for various microbubble generation.

This study makes a claim of utilizing the photothermal effect of graphene oxide nanosheets (GONs) to effectively produce various microbubbles in an optical microfiber system at infrared optical communications band. A low power continuous-wave light at wavelength of 1527-1566 nm was launched into the microfiber to form GONs-deposition which acted as a linear heat source for creating various microbubbles. Both thermal convection flow and optical gradient force were responsible for the driving force to assemble GONs onto the microfiber.
