Single-Cell Heterogeneity of EGFR Pathway Is Linked to Unique Signatures of Drug Response and Malignancy in Patient Derived Glioblastoma Stem Cells.

Purpose: In glioblastoma, the therapeutically intractable and resistant phenotypes can be derived from glioma stem cells, which often have different underlying mechanisms from non-stem glioma cells. Aberrant signaling across the EGFR-PTEN-AKT-mTOR pathways have been shown as common drivers of glioblastoma. Revealing the inter and intra-cellular heterogeneity within glioma stem cell populations in relations to signaling patterns through these pathways may be key to precision diagnostic and therapeutic targeting of these cells.

Use of the Superior Thyroid Artery as a Recipient Artery in Head and Neck Free Flap Reconstruction: Effects on Post-Operative Hypothyroidism.

Background: The superior thyroid artery (STA) as a recipient vessel in free flap reconstruction may theoretically impact thyroid function. This study aimed to assess whether the use of the STA has an adverse effect on thyroid function.

Methods: Retrospective review of 101 head and neck reconstructive cases.

Demographic and Clinical Characteristics of Mild, Young and Early COPD: A Cross-Sectional Analysis of 5468 Patients.

Early, mild and young COPD concepts are not clearly defined and are often used interchangeably to refer to the onset of the disease. : To describe and compare the characteristics of mild, young and early COPD in a large sample of COPD from primary and secondary care. : Pooled analysis of individual data from four multicenter observational studies of patients with stable COPD (≥40 years, FEV/FVC < 0.

Colocalization of hedgehog arterivirus 1 (HhAV-1) and histologic lesions in the European hedgehog () with neurological disease.

The European hedgehog () is a protected species of conservation concern in the UK. In recent years, there have been multiple incidents of fatal encephalitis in captive hedgehogs in wildlife rescue centers associated with the molecular detection of a hedgehog arterivirus (HhAV-1). However, it remains unclear whether the virus is the causative agent of the central nervous system (CNS) lesions.

The Presence of Type Va Double Common Bile Duct in a Male Patient: A Case Report.

Double common bile duct (DCBD) is a rare congenital anomaly of the biliary system, characterized by the presence of two common bile ducts. The condition can be classified into five distinct types. Type Va DCBD is one of the rare congenital variations where both bile ducts open separately into the duodenum: one opens normally at the major duodenal papilla, and the second opens independently into the duodenum at a different site, usually proximal to the major duodenal papilla.
