The accumulation of lactate in tissue microenvironments is associated with atherosclerosis, but its precise role in atherogenesis remains largely unknown. This study demonstrated that lactate accumulation in aortic tissues and blood is correlated with increased monocarboxylate transporter 1 (Mct1) expression in endothelial cells (ECs) within atherosclerotic plaques. Lactate uptake via Mct1 triggers an inflammatory response in ECs.

Since there are no apparent symptoms in the early stages of carotid atherosclerosis onset, it causes a more significant clinical diagnosis. Photoacoustic (PA) imaging provides high contrast and good depth information, which has been used for the early detection and diagnosis of many diseases.

Dysregulated glucose and lipid metabolism is recognized as a hallmark of tumors but has not thoroughly been elucidated in neointima formation. Here, we investigated the cooperative role of glycolysis and fatty acid synthesis in vascular injury-induced VSMC dedifferentiation and neointima formation.

Conventional laboratory indicators require hours for coagulopathy diagnosis, which brings difficulties for appropriate intervention within the optimal window. This study evaluates the possibility of building efficient coagulopathy prediction models using data mining and machine learning algorithms.

Objective: To investigate miR-20a expression in human glioma and normal brain tissues and its effect on the proliferation of glioma cells in vitro.
Methods: The expression of miR-20a was detected in human normal brain tissues and glioma tissues by real-time RT-PCR. miR-20a mimics were synthesized and transfected into U251 cells via liposome, and the cell proliferation were detected using MTT assay and flow cytometry.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gut. It is characterized by positive immunostaining for CD117, and bears mutations in the c-kit or PDGFRA genes. Its origin remains uncertain.

Methods: Fifty two cases of GIST and 28 cases of other tumors were examined. DNA samples were extracted from paraffin sections and fresh blocks.
