Meldonium Inhibits Cell Motility and Wound-Healing in Trabecular Meshwork Cells and Scleral Fibroblasts: Possible Applications in Glaucoma.

Meldonium (MID) is a synthetic drug designed to decrease the availability of L-carnitine-a main player in mitochondrial energy generation-thus modulating the cell pathways of energy metabolism. Its clinical effects are mostly evident in blood vessels during ischemic events, when the hyperproduction of endogenous carnitine enhances cell metabolic activities, leading to increased oxidative stress and apoptosis. MID has shown vaso-protective effects in model systems of endothelial dysfunction induced by high glucose or by hypertension.

Extremely low-frequency electromagnetic fields (ELF-MF) can modify the cell viability and regulatory processes of some cell types, including breast cancer cells. Breast cancer is a multifactorial disease where a role for ELF-MF cannot be excluded. ELF-MF may influence the biological properties of breast cells through molecular mechanisms and signaling pathways that are still unclear.

Accurate Analysis of Lipid Building Blocks Using the Tool LipidOne.

LC/MS-based analysis techniques combined with specialized lipid platforms allow the qualitative and quantitative determination of thousands of lipid molecules. Each individual molecule can be considered as an assembly of smaller parts, often called building blocks that are the result of a myriad of biochemical synthesis and transformation processes. LipidOne is a new lipidomic tool that automatically highlights all qualitative and quantitative changes in lipid building blocks both among all detected lipid classes and between experimental groups.

Effects of the Exposure of Human Non-Tumour Cells to Sera of Pancreatic Cancer Patients.

Pancreatic ductal adenocarcinoma (PDAC) has high metastatic potential. The "genometastasis" theory proposes that the blood of some cancer patients contains elements able to transform healthy cells by transferring oncogenes. Since findings on genometastasis in PDAC are still scarce, we sought supporting evidence by treating non-tumour HEK293T and hTERT-HPNE human cell lines with sera of PDAC patients.

Possible risk factors involved in psychological and emotional stress and depression among forensic medicine workers.

Introduction: Different forms of rationalization are introduced through work, which result from economic, political, and social changes that increase the need for labor force. Within this context, there are institutions that neglect the effects of poor work environments on workers' health, such as the development of work-related mental and psychological disorders.

Objectives: To understand what it means to work as an official expert at a forensic medicine institute and investigate occupational and workplace factors that may contribute to emotional and psychological stress and/or depression.

However, the existing tools have the limitation to treat only the assembled lipid molecules.

Conceptual Analogies Between Multi-Scale Feeding and Feedback Cycles in Supermassive Black Hole and Cancer Environments.

Adopting three physically-motivated scales ("micro" - "meso" - "macro", which refer to mpc - kpc - Mpc, respectively) is paramount for achieving a unified theory of multiphase active galactic nuclei feeding and feedback, and it represents a keystone for astrophysical simulations and observations in the upcoming years. In order to promote this multi-scale idea, we have decided to adopt an interdisciplinary approach, exploring the possible conceptual similarities between supermassive black hole feeding and feedback cycles and the dynamics occurring in human cancer microenvironment.

Role of primary cilium in pancreatic ductal adenocarcinoma (Review).

The primary cilium is a non‑motile cellular structure extending from the apical membrane of epithelial cells that is involved in several processes due to its ability to receive and elaborate different signals. Ciliogenesis and its obliteration are essential for proliferating cells, and several signalling pathways are responsible for their regulation. In fact, the primary cilium is a central hub for numerous signalling pathways implicated in a variety of biological processes, such as the Hedgehog, mammalian target of rapamycin and Wnt pathways.
