Ancient Greeks drew advice from oracles, dreams, entrails, the movements of birds, sneezes, and myriad other sources for divination. Classicists typically study such phenomena as examples of occult religion, or for their use as a social mechanism for managing dissent and forging consensus. Ancient philosophical accounts by contrast go a longer way toward considering them seriously, on their own terms. They take them as an invitation into developing speculative accounts of non-standard epistemological schemes...

Introduction A P2Y12 inhibitor plus aspirin is the most widely used antiplatelet strategy to prevent adverse outcomes in the setting of atherothrombotic vascular disease. Areas Covered A paucity of robust evidence for an optimal dose, gastrointestinal toxicity, ineffectiveness in high-risk patients and interactions with other antiplatelet agents, are major controversies associated with aspirin therapy. Ticagrelor is a reversibly binding oral P2Y12 receptor blocker that mediates potent inhibition of adenosine diphosphate-induced platelet function...

After acute coronary syndromes (ACS), the so-called dual antiplatelet therapy (DAPT), which usually consists of low-dose of aspirin in combination with a thienopyridine (clopidogrel, prasugrel) or with a cyclopentyltriazolopyrimidine (ticagrelor), reduces the risk of ischemic events. Ticagrelor, un particular, is an effective drug as it isn' a prodrug, doesn't require metabolic activation and demonstrates a rapid onset and faster offset of action. Areas covered: This article evaluates the pharmacokinetics, efficacy, safety and tolerability of ticagrelor during DAPT after ACS and its potential use beyond the canonical twelve months after PCI...

The purpose of this study was to evaluate the dosimetric impact of cylinder size in high-dose-rate (HDR) vaginal cuff brachytherapy (VCBT). Sample plans of HDR VCBT in a list of cylinders ranging from 2.5 to 4 cm in diameter at 0.5 cm incre-ment were created and analyzed. The doses were prescribed either at the 0.5cm depth with 5.5 Gy for 4 fractions or at the cylinder surface with 8.8 Gy for 4 frac-tions, in various treatment lengths. A 0.5 cm shell volume called PTV_Eval was contoured for each plan and served as the target volume for dosimetric evaluation...

Ticagrelor is an antagonist of the platelet P2Y12 receptor for ADP, approved for the prevention of thromboembolic events in patients with acute coronary syndrome. Previous studies showed that ticagrelor has no significant activity versus P1 receptors for adenosine and other known P2Y receptors, with the exception of P2Y13, which was not tested. The P2Y12 antagonist cangrelor has been shown to also inhibit P2Y13 and to decrease the P2Y13-regulated capacity of megakaryocytes to produce pro-platelets. We tested whether or not ticagrelor inhibits P2Y13 signalling and function...

BACKGROUND AND PURPOSE: Intensity modulated radiotherapy requires all target areas to be treated by a single radiotherapy plan. In anal cancer, the pelvic nodes, inguinal nodes and primary tumour represent three different targets. We aim to calculate target-specific motion in anal cancer radiotherapy, when delivered using a single pelvic online auto-match. MATERIALS AND METHODS: Twenty consecutive patients treated using IMRT at a single institution were studied...

Oxaliplatin resistance in colorectal cancers (CRC) is a major medical problem, and predictive markers are urgently needed. Recently, miR-625-3p was reported as a promising predictive marker. Herein, we show that miR-625-3p functionally induces oxaliplatin resistance in CRC cells, and identify the signalling networks affected by miR-625-3p. We show that the p38 MAPK activator MAP2K6 is a direct target of miR-625-3p, and, accordingly, is downregulated in non-responder patients of oxaliplatin therapy. miR-625-3p-mediated resistance is reversed by anti-miR-625-3p treatment and ectopic expression of a miR-625-3p insensitive MAP2K6 variant...

BACKGROUND: Melancholia is a kind of depression with the most common symptoms of evident mental disorder, slimness, lack of enjoyment, feeling guilty and having no appetite. In modern medicine, the word "melancholia" only refers to mental and affective symptoms of depression. However, historically, it could have physical symptoms as well as mental symptoms and the atrabilious situations were categorized according to their common reasons rather than their specific characteristics. This study aimed to enlighten the history of this disease...

BACKGROUND & AIMS: Interactions between C-C chemokine receptor types 2 (CCR2) and 5 (CCR5) and their ligands, including CCL2 and CCL5, mediate fibrogenesis by promoting monocyte/macrophage recruitment and tissue infiltration, as well as hepatic stellate cell activation. Cenicriviroc (CVC) is an oral, dual CCR2/CCR5 antagonist with nanomolar potency against both receptors. CVC's anti-inflammatory and antifibrotic effects were evaluated in a range of preclinical models of inflammation and fibrosis...
