Flavonolignans are the main components of silymarin, which represents 1.5-3% of the dry fruit weight of Milk thistle (Silybum marianum L. Gaernt.). In ancient Greece and Romania, physicians and herbalists used the Silybum marianum to treat a range of liver diseases. Besides their hepatoprotective action, silymarin flavonolignans have many other healthy properties, such as anti-platelet and anti-inflammatory actions. The aim of this study was to evaluate the toxic effect of flavonolignans on blood platelets, peripheral blood mononuclear cells (PBMCs) and human lung cancer cell line-A549-using different molecular techniques...

The development of advanced cervical cancer therapies is a particularly urgent need due to the strong side effects and toxicities of current treatments. Caffeic acid phenethyl ester (CAPE) exhibits broad-spectrum antitumor activities and little toxicity or side effects. In our previous study, caffeic acid para-nitro phenethyl ester (CAPE-pNO2) significantly improved the effect of anti-platelet aggregation and attenuated myocardial ischemia. Based on this finding, we aimed to further explore the antitumor activity of CAPE-pNO2 in cervical cancer cells and tumor xenografts...

Deep vein thrombosis (DVT) associates with considerable morbidity, functional disability and mortality. Due to the lack of suitable inhibitor the correlation of various factors in DVT onset remains unknown. In this context we analyzed the structure of anti-platelet aggregation agent, P-selectin down-regulator, GPIIb/IIIa down-regulator and anti-inflammatory agent, thereby designed N-(3S-1,2,3,4-tetrahydroisoquinoline-3-carbonyl)- Thr-Ala-Arg-Gly-Asp(Val)-Val (IQCA-TAVV) as an inhibitor of DVT to receive evaluations...

The present study was designed to explore the anti-inflammatory activity of an anti-platelet agent crinumin, by various in vitro and in vivo inflammation models. Firstly, crinumin protein was purified through cation exchange chromatography; then, in vitro activity was estimated by albumin denaturation assay and HRBC membrane stabilization assay. Carrageenan-induced paw oedema and cotton pellet-induced granuloma models were used for in vivo anti-inflammatory activity assessment in rats. In both models, rats were pre-treated for 7 days with crinumin (25-50 µg/ml) and diclofenac sodium (50 µg/ml)...

BACKGROUND/AIMS: Platelets affect endothelial progenitor cell (EPC) functionality, inducing their differentiation into mature endothelial cells. However, it remains to be established whether EPCs can influence platelet functionality. METHODS: Mononuclear proangiogenic cells (MPCs) and early outgrowth cells (EOCs) were prepared from peripheral blood mononuclear cells, whereas late-outgrowth endothelial cells (OECs) were prepared from cord blood CD34+ cells. The effect of the above cells and their supernatants on washed platelet aggregation was studied...

REVIEW
Martin W Bergmann, Carsten W Israel
In Europe left atrial appendage occluders (LAAO) are most frequently used in patients with contraindications for oral anticoagulation (OAC); therefore, the classical therapeutic OAC scheme from the PROTECT-AF trial (vitamin K antagonist plus acetylsalicylic acid) is usually changed to dual anti-platelet therapy (DAPT) after implantation of a Watchman® or Amulet® LAAO (St. Jude Medical/Abbott, Eschborn, Germany). For many years, patients with an LAAO received DAPT for 1-6 months. The current standard comprises DAPT for 3 months, followed by permanent acetylsalicylic acid monotherapy if the transesophageal echocardiogram excludes a thrombus at the site of the LAAO...

The classic Virchow theory suggests that blood stasis, hypercoagulability and endothelial dysfunction are three major factors that cause venous thrombosis (VT). It is a complicated biological process involved multi-factors. Platelet plays a central role and participates in multiple links of this process. Panax notoginseng saponins (PNS), the principal constituents derived from panax notoginseng, has been widely described for its anti-platelet activity. However, its potential mechanism against platelet aggregation has not been clarified...

BACKGROUND: The benefit of antiplatelet medication in confirmed acute coronary syndrome (ACS) is well established. In the Emergency Department (ED) diagnostic uncertainty may lead to over-treatment, with consequent risks (e.g., bleeding), or under-treatment, compromising clinical outcomes. Clinicians must subjectively balance the anticipated risks and benefits with their perceived probability of ACS in order to decide whether to prescribe these medications. We aimed to construct a clinical model to optimise and personalise recommendations for anti-platelet prescription in this context...

BACKGROUND: The optimal management of minor head injured patients with brain injury identified by CT imaging is unclear. Some guidelines recommend routine hospital admission of GCS13-15 patients with traumatic brain (TBI) injury identified by CT imaging. Others argue that selected lower-risk patients can be discharged from the Emergency Department (ED). OBJECTIVE: To estimate the risk of death, neurosurgery and clinical deterioration minor head injured patients with TBI identified by CT imaging, and assess which factors affect the risk of these outcomes...

BACKGROUND: Platelet activation and subsequent accumulation at sites of vascular injury perform a central role in thrombus formation, which is believed to be the trigger of several cardiovascular diseases, such as atherosclerosis, myocardial infarction and strokes. In this sense, the search for agents that are capable of blocking platelets aggregation has important implications for these diseases. Callicarpa nudiflora (C. nudiflora) Hook is a traditional Chinese medicine herb for eliminating stasis to subdue swelling and hemostasis...

In atherosclerotic animal models, the cyclo-oxygenase (COX)-inhibitor aspirin counteracts downregulation of endothelial-derived netrin-1, thus reducing arterial inflammation. We here explored the effect of aspirin on netrin-1 in healthy subjects undergoing influenza immunisation, which is an established experimental model of inflammation-related endothelial dysfunction. Our data showed that netrin-1 undergoes reduction (-29.25% from baseline; p=0.0017) in the presence of endothelial activation (VCAM-1 rose by 9...

Objective: Acute subdural hematoma (ASDH) is generally considered a condition that should be managed surgically. However, some patients initially receive conservative treatment, a subset of whom require surgical intervention later. This study aimed to evaluate the predictors of delayed surgical intervention in ASDH patients who are initially managed conservatively. Methods: From January 2007 to December 2015, 842 patients diagnosed with ASDH were treated at our institution...

OBJECTIVE: Facing mild traumatic brain injury, clinicians must decide whether to perform a computed tomography (CT) scan to detect a potential intracranial hemorrhage. Many useful guidelines have been developed for the general population, but there is no general consensus about the best practice to adopt when dealing with patients on antiplatelet or anticoagulation drugs. The relatively recent introduction of new anticoagulants and second-generation antiplatelet drugs poses new challenges in this field...
