Transcendental meditation for lowering blood pressure: An overview of systematic reviews and meta-analyses.

Background: Transcendental meditation (TM) is a stress reduction technique that can potentially lower blood pressure (BP) safely. The American Heart Association recommends that TM may be considered in clinical practice.

Objective: To provide an overview of all systematic reviews and meta-analyses of TM on BP for evidence-informed clinical decision making.

A Risk Score Derived from the Analysis of a Cluster of 27 Serum Inflammatory Cytokines to Predict Long Term Outcome in Patients with Acute Myocardial Infarction: a Pilot Study.

Background: The aim of our study was to evaluate the clinical utility and prognostic significance of a cluster of 27 serum cytokines for risk stratification after myocardial infarction.

Materials And Methods: We enrolled 33 consecutive patients admitted to our institution for acute myocardial infarction and prospectively followed. We evaluated traditional cardiovascular risk factors and assayed, during the acute phase, 27 serum cytokines (IL-1, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL -7, IL-8, IL-9, IL-10, IL-12, IL-13, IL-15, IL-17, EOTAXIN, FGF, G-CSF, GM-CSF, IFN-γ, IP-10, MCP-1, MIP-1α, MIP-1β, PDGF, RANTES, TNF-α, VEGF) potentially associated with cardiovascular risk.

Lattice expansion of highly oriented 2D phthalocyanine covalent organic framework films.

Expanding into application: covalent organic framework (COF) films are ideally suited for vertical charge transport and serve as precursors of ordered heterojunctions. Their pores, however, were previously too small to accommodate continuous networks of complementary electron acceptors. Four phthalocyanine COFs with increased pore size well into the mesoporous regime are now described.

Atherosclerosis, inflammation and Chlamydia pneumoniae.

Coronary heart disease is the single most common cause of illness and death in the developed world. Coronary atherosclerosis is by far the most frequent cause of ischemic heart disease, and plaque disruption with superimposed thrombosis is the main cause of the acute coronary syndromes of unstable angina, myocardial infarction, and sudden death. Atherosclerosis is the result of a complex interaction between blood elements, disturbed flow, and vessel wall abnormality, involving several pathological processes: inflammation, with increased endothelial permeability, endothelial activation, and monocyte recruitment; growth, with smooth muscle cell proliferation, migration, and matrix synthesis; degeneration, with lipid accumulation; necrosis, possibly related to the cytotoxic effect of oxidized lipid; calcification/ossification, which may represent an active rather than a dystrophic process; and thrombosis, with platelet recruitment and fibrin formation.

Cytostatic activity of paclitaxel in coronary artery smooth muscle cells is mediated through transient mitotic arrest followed by permanent post-mitotic arrest: comparison with cancer cells.

The anti-cancer agent paclitaxel (PTX) is an effective anti-restenosis agent on drug eluting stents, primarily due to growth inhibition of coronary artery smooth muscle cells (CASMC) across a wide dose range. In this study, we compared the effects of PTX on CASMC to apoptotic-prone HL60 leukemia cells and apoptotic-reluctant A549 lung cancer cells to assess cell survival mechanisms. In comparison to HL60 and A549 cells, CASMC had a shorter mitotic arrest and a lower mitotic index.
