Targeting the Endothelin-1 pathway to reduce invasion and chemoresistance in gallbladder cancer cells.

Background: Gallbladder cancer (GBC) is a prevalent and deadly biliary tract carcinoma, often diagnosed at advanced stages with limited treatment options. The 5-year survival rate varies widely from 4 to 60%, mainly due to differences in disease stage detection. With only a small fraction of patients having resectable tumors and a high incidence of metastasis, advanced GBC stages are characterized by significant chemoresistance.

Characteristics of fungemia in a peruvian referral center: 5-year retrospective analysis.

Retrospective descriptive study carried out to determine the characteristics of fungemia in 285 cancer patients hospitalized from 2012 to 2016 at the Instituto Nacional de Enfermedades Neoplásicas (INEN). Demographic, clinical and microbiological information was evaluated. Fungemia by C.

A Thyroid Genetic Classifier Correctly Predicts Benign Nodules with Indeterminate Cytology: Two Independent, Multicenter, Prospective Validation Trials.

Although most thyroid nodules with indeterminate cytology are benign, in most of the world, surgery remains as the most frequent diagnostic approach. We have previously reported a 10-gene thyroid genetic classifier, which accurately predicts benign thyroid nodules. The assay is a prototype diagnostic kit suitable for reference laboratory testing and could potentially avoid unnecessary diagnostic surgery in patients with indeterminate thyroid cytology.

Prefrontal working memory activity predicts episodic memory performance: A neuroimaging study.

Working memory (WM) and long term memory (LTM) are different neuropsychological processes, although distinction between these domains is an area of debate. LTM is thought to rely on hippocampal circuitry. Cognitive neuroscience models imply that WM processing may at least partially support LTM within regions of the prefrontal cortex (PFC).

Alterations to task positive and task negative networks during executive functioning in Mild Cognitive Impairment.

Poor executive functioning increases risk of decline in Mild Cognitive Impairment (MCI). Executive functioning can be conceptualized within the framework of working memory. While some components are responsible for maintaining representations in working memory, the central executive is involved in the manipulation of information and creation of new representations.
