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...

Temporary mechanical circulatory support (TCS) is recommended for patients with profound cardiogenic shock (CS). Extracorporeal membrane oxygenation (ECMO) and Impella are possible TCS devices, but the device choice and the implantation timing are not definitely established, specifically during acute myocardial infarction. We have analyzed the respective use of ECMO or Impella (2.5, CP, or 5.0) for CS following acute myocardial infarction , from a cohort of patients who underwent TCS within 72 hours after admission for emergency percutaneous coronary intervention (PCI) from January 2009 to April 2015...

Maintenance or reconstruction of interproximal papilla for a successful dental implant restoration can be challenging. To date, the results from various surgical and prosthetic techniques to maintain or regenerate papilla adjacent to dental implants have been unpredictable. To maintain the quality of the soft tissue around an implant, the blood supply must be preserved and formation of scar tissue must be minimized during surgery. Therefore, incision design is vital to producing an esthetic and successful dental implant restoration...

Chimeric antigen receptor (CAR) T cells represent a novel targeted approach to overcome both quantitative and qualitative shortfalls of the host immune system relating to the detection and subsequent destruction of tumors. The identification of antigens expressed specifically on the surface of tumor cells is a critical first step in the ability to utilize CAR T cells for the treatment of cancer. The 5T4 is a tumor-associated antigen which is expressed on the cell surface of most solid tumors including ovarian cancer...

Human milk oligosaccharides (HMOs) afford many health benefits to breast-fed infants, such as protection against infection and regulation of the immune system, through the formation of non-covalent interactions with protein receptors. However, the molecular details of these interactions are poorly understood. Here, we describe the application of catch-and-release electrospray ionization mass spectrometry (CaR-ESI-MS) for screening natural libraries of HMOs against lectins. The HMOs in the libraries were first identified based on molecular weights (MWs), ion mobility separation arrival times (IMS-ATs) and collision-induced dissociation (CID) fingerprints of their deprotonated anions...

Little is known about engagement and retention in care of people diagnosed with chronic hepatitis C (HCV) in England. Establishing a cascade of care informs targeted interventions for improving case-finding, referral, treatment uptake and retention in care. Using data from the Sentinel Surveillance of Blood Borne Virus testing (SSBBV) between 2005-2014 we investigate the continuum of care of those tested for HCV in England. Persons ≥1 years old, with an anti-HCV test and subsequent RNA tests between 2005-2014 reported to SSBBV were collated...

The analysis of leukocytes of peripheral blood is a crucial step in hematologic exams commonly used for disease diagnosis and, typically, requires molecular labelling. In addition, only a detailed, laborious phenotypic analysis allows identifying the presence and stage of specific pathologies such as leukemia. Most of the biochemical information is lost in the routine blood tests. In the present study, we tackle two important issues of label-free biochemical identification and classification of leukocytes using Raman spectroscopy...

Paracetamol is arguably the most commonly used analgesic and antipyretic drug worldwide, however its mechanism of action is still not fully established. It has been shown to exert effects through multiple pathways, some actions suggested to be mediated via N-arachidonoylphenolamine (AM404). AM404, formed through conjugation of paracetamol-derived p-aminophenol with arachidonic acid in the brain, is an activator of the capsaicin receptor, TRPV1, and inhibits the reuptake of the endocannabinoid, anandamide, into postsynaptic neurons, as well as inhibiting synthesis of PGE2 by COX-2...

  Osteoclasts are bone-resorbing giant polykaryons that differentiate from mononuclear macrophage/monocyte-lineage hematopoietic precursors. We have originally established an advanced imaging system for visualizing in vivo behavior of osteoclasts and their precursors with intravital two-photon microscopy. By means of the system, we found that sphingosine-1-phosphate, a lipid mediator enriched in blood, controlled the migratory behavior of osteoclast precursors. We also developed pH-sensing chemical fluorescent probes to detect localized acidification by bone-resorbing osteoclasts on the bone surface in vivo, and identified two distinct functional states of differentiated osteoclasts, 'bone-resorptive' and 'non-resorptive'...

Individuals with prehypertension have a greater risk of developing hypertension and cardiovascular disease than those with normal blood pressure. Good cardiorespiratory fitness has been associated with a reduced risk for cardiovascular diseases, but whether it is related to slower progression of early atherosclerosis is unclear. We evaluated 442 women, aged 40-60 years, with resting systolic blood pressure 120-139 mmHg and diastolic blood pressure 80-89 mmHg, defined as prehypertension in cross-sectional study...

Gastrointestinal stromal tumors (GISTs) are rare life-threatening forms of cancer that may arise anywhere in the GI tract. Herein, we aimed to review the literature to describe the incidence, management, and outcomes of GISTs. We conducted a traditional narrative review using PubMed and EMBASE, searching for English-language publications for GISTs between January 2001 and January 2016 using keywords "gastrointestinal" "stromal tumors." Among 4582 retrieved articles, 50 articles were relevant over the last 15 years...

Recently discovered broadly neutralizing anti-HIV-1 antibodies (bNAbs) demonstrate extensive breadth and potency against diverse HIV-1 strains, and represent a promising approach for the treatment and prevention of HIV-1 infection. The breadth and potency of these antibodies have primarily been evaluated using panels of HIV-1 Env-pseudotyped viruses produced in 293T cells expressing molecularly cloned Envs. Here we report on the ability of 5 bNAbs currently in clinical development to neutralize circulating primary HIV-1 isolates derived from peripheral blood mononuclear cells (PBMC), and compare the results to the pseudovirus panels used to characterize the bNAbs...

During prenatal development the liver is composed of multiple cell types with unique properties compared to their adult counterparts. We aimed to establish multilineage cultures of human fetal liver cells that could maintain stem cell and progenitor populations found in the developing liver. An aim of this study was to test if maturation of fetal hepatocytes in short-term cultures supported by epidermal growth factor and oncostatin M can improve their ability to engraft immunodeficient mice. Fetal liver cultures supported a mixture of albumin+ cytokertin-19+ hepatoblasts, hepatocytes, cholangiocytes, CD14++CD32+ liver sinusoidal endothelial cells (LSECs) and CD34+CD133+ haematopoietic stem cells...
