Microglial Morphometric Parameters Correlate With the Expression Level of IL-1&#x3b2;, and Allow Identifying Different Activated Morphotypes.
Microglia are the resident macrophages in the brain. Traditionally, two forms of microglia have been described: one considered as a resting/surveillant state in which cells have a highly branched morphology, and another considered as an activated state in which they acquire a de-ramified or amoeboid form. However, many...

Independent Validation of the Colloid Cyst Risk Score to Predict Symptoms and Hydrocephalus in Patients with Colloid Cysts of the Third Ventricle.
The Colloid Cyst Risk Score (CCRS) was devised to identify patients with symptomatic colloid cyst and stratify risk of hydrocephalus. The CCRS considers patient age, presence of headache, colloid cyst diameter, fluid-attenuated inversion recovery hyperintensity, and location within the third ventricle.</AbstractText>Th...

MicroRNA-429 inhibits bone metastasis in breast cancer by regulating CrkL and MMP-9.
Bone metastasis is common in late-stage breast cancer patients and leads to skeletal-related events that affect the quality of life and decrease survival. Numerous miRNAs have been confirmed to be involved in metastatic breast cancer, such as the miR200 family. Our previous study identified microRNA-429 (miR-429) as a ...

Influence of wide opening of the lateral ventricle on survival for supratentorial glioblastoma patients with radiotherapy and concomitant temozolomide-based chemotherapy.
The prognosis for glioblastoma (GBM) varies among patients. Ventricular opening during surgery has been reported as a prognostic factor for GBM patients, but the influence of ventricular opening itself on patient prognosis remains controversial. We presumed that the degree of ventricular opening would correlate with th...

Diffused light attenuation at 664 nm for PDT in salted cadaver brain.
We investigated light attenuation at 664&#x2009;nm, which is the excitation wavelength of photodynamic therapy (PDT) using talaporfin sodium, in a salted cadaver brain. Estimation of therapeutic lesions is important to ensure the effectiveness and safety of brain tumor PDT. Previously reported optical properties of the...
