Development of efficient biodegradable, environmentally responsive, biocompatible and non-toxic delivery system is needed for efficient gene delivery. As well known, properties of the vehicle are determined by the structure of carrier components. The aim of the current study was to estimate in vitro transfection efficacy of aliphatic di-, tri- and tetrapeptide-based cationic lipoplexes loaded with siRNA in function of a number of cationic groups using 2D (monolayer culture) and 3D (multicellular tumor spheroids) in vitro models...

Carbendazim is a fungicide commonly used as active substance in plant protection products and biocidal products, for instance to protect facades of buildings against fungi. However, the subsequent occurrence of this fungicide and potential endocrine disruptor in the aqueous environment is a major concern. In this study, high resolution mass spectrometry shows that carbendazim can be detected with an increasing abundance from the source to the mouth of the River Rhine. Unexpectedly, the abundance of carbendazim correlates poorly with that of other fungicides used as active ingredients in plant protection products (r2 of 0...

INTRODUCTION: Diagnosing lymphoma continues to prove challenging in the clinical practice. Composite lymphoma (CL) is defined by the coexistence of different lymphoma subtypes in the same anatomical location. This condition has seldom been witnessed in the gastrointestinal (GI) tract. We weren't able to find previous cases in the literature about small bowel CL with follicular lymphoma (FL) and classical Hodgkin lymphoma (CHL). Surgery is the treatment of choice to obtain accurate histology, to manage and prevent acute complications...

Out-of-hospital cardiac arrest (OHCA) is considered an important public health issue but its incidence has not been examined in France. The aim of this study is to define the incidence of OHCA in France and to compare this to other neighbouring countries. Data were extracted from the French OHCA registry. Only exhaustive centres during the period from January 1, 2013, to September 30, 2014 were included. All patients were included, regardless of their age and cause of OHCA. The participating centres covered about 10% of the French population...

Gestational Diabetes Mellitus is a condition strongly related to the development of type 2 diabetes later in life, although the risk and the onset have not been fully identified yet. Although glucose tolerance returns to normal levels after delivery in the majority of women with GDM, this condition represents an early stage in the natural history of T2DM. In addition, women with previous GDM exhibit an increased cardiovascular risk profile and a raised incidence of cardiovascular diseases. Lifestyle changes and pharmacological interventions might be able to reduce the incidence of type 2 diabetes in pGDM women, although results are still not conclusive...

In the last few years, molecular targeted therapies have replaced traditional cytotoxic chemotherapy in the fight against many cancers to the extent that our understanding of tumor biology has become more sophisticated. This shift has markedly changed adverse event profiles, compared to cytotoxic chemotherapy, affecting a diverse range of organ systems. Everolimus was approved by the FDA in 2011 for the treatment of progressive pancreatic NE tumors (Yao, 2011; Jensenn, 2012). It is an inhibitor of mammalian target of rapamycin (mTOR) and exhibits antitumor activity via disruption of various signaling pathways and it's used in the treatment of advanced renal cell cancer, breast cancer and neuroendocrine tumors (NET); it's used also as anti-rejection agent for transplantation but with lower doses for anti-rejection (1...

Huntington's disease (HD) is a devastating, progressive neurodegenerative disease with a distinct phenotype characterized by chorea and dystonia, incoordination, cognitive decline and behavioral difficulties. The precise mechanisms of HD progression are poorly understood; however, it is known that there is an expansion of the trinucleotide cytosine-guanosine-guanine (CAG) repeat in the Huntingtin gene. Herein DI/LC-MS/MS was used to accurately identify and quantify 185 metabolites in post mortem frontal lobe and striatum from HD patients and healthy control cases...

Plant cystatins are involved in the regulation of protein turnover and play important roles in defense mechanisms. We cloned the ApCystatin gene from Agapanthus praecox ssp. orientalis, a famous ornamental and medical plant. The complete cDNA sequence of ApCystatin is comprised of 1446 nucleotides with a 420 bp ORF encoding 140 amino acids. The mRNA level of ApCystatin was significantly up-regulated under various abiotic stress, such as salt, osmosis, oxidative and cold stresses, which suggested that ApCystatin participated in the plant's resistance to stress...

Engineered fluorescent indicators for visualizing mercury ion (Hg2+ ) are powerful tools to illustrate the intracellular distribution and serious toxicity of the ion. However, the sensitive and specific detection of Hg2+ in living cells and in vivo is challenging. This paper reported the development of fluorescent indicators for Hg2+ in green or red color by inserting a circularly permuted fluorescent protein into a highly mercury-specific repressor. These sensors provided a rapid, sensitive, specific, and real-time read-out of Hg2+ dynamics in solutions, bacteria, subcellular organelles of mammalian cells, and zebrafish, thereby providing a useful new method for Hg2+ detection and bioimaging...

The transcription factor nuclear factor E2-related factor 2 (Nrf2) is known to control the expression of antioxidant response elements and cytoprotective genes and modulate inflammatory response, helping to ameliorate damage in many diseases. Exactly how Nrf2 regulates innate inflammatory homeostasis remains unclear. In this study, we provide in vitro and in vivo evidence that Nrf2 plays a crucial role in macrophage polarization and acute respiratory distress syndrome (ARDS). We conducted in vitro experiments using a mouse alveolar macrophage cell line as well as primary cultures of macrophages in which cells were exposed to lipopolysaccharide (LPS) or interferon-γ in order to mimic ARDS, in the presence or absence of the Nrf2 activator tert-butylhydroquinone (tBHQ)...

Antimicrobial peptides, also called Host Defence Peptides (HDPs), are effectors of innate immune response found in all living organisms. In a previous report, we have identified by chemical fragmentation, and characterized the first cryptic antimicrobial peptide in PD-L4, a type 1 ribosome-inactivating protein (RIP) from leaves of Phytolacca dioica L. We applied a recently developed bioinformatic approach to a further member of the differently expressed pool of type 1 RIPs from P. dioica (PD-L1/2), and identified two novel putative cryptic HDPs in its N-terminal domain...

Tr1 cell therapy is considered an emerging approach to improve transplant tolerance and enhance allogeneic graft survival. However, it remains unclear how Tr1 cells promote transplant tolerance and whether they will be safe and stable in the face of an acute viral infection. By employing a mouse model of pancreatic islet transplantation, we report that Tr1 cell therapy promoted transplant tolerance via de novo induction of Tr1 cells in the recipients. Acute viral infection with lymphocytic choriomeningitis virus (LCMV) had no impact on Tr1 cell number and function, neither on the Tr1 cells infused nor on the ones induced, and that was reflected in the robust maintenance of the graft...

Eltrombopag is an oral thrombopoietin-receptor-agonist (TPO-RA) approved for the treatment of patients with chronic idiopathic thrombocytopenic purpura (ITP), who are more than one year old, and show poor response to first-line therapy. ITP is a hematological disorder characterized by isolated thrombocytopenia in the absence of secondary causes or disorders. Eltrombopag is generally well tolerated in the pediatric population, therefore therapeutic drug monitoring (TDM) is not usually performed in clinical practice...

Totally implantable venous access device (TIVAD) lumen occlusion is a long-term complication of central venous catheters, associated with risks of infection, therapy interruptions and increased healthcare costs. The role of flushing and locking in maintaining TIVAD patency is paramount. Most flushing protocols are based on manufacturers' recommendations, which indicate that 4 weeks is the safest interval between two consecutive flushing procedures during periods when TIVADs are not in use. Conversely, results of several studies suggest that extended flushing intervals (FIs) do not increase the rate of obstructive or infective complications...

Cyclodextrin (CD) complexation is a convenient method to sequester surfactants in a controllable way, for example, during membrane-protein reconstitution. Interestingly, the equilibrium stability of CD/surfactant inclusion complexes increases with the length of the nonpolar surfactant chain even beyond the point where all hydrophobic contacts within the canonical CD cavity are saturated. To rationalize this observation, we have dissected the inclusion complexation equilibria of a structurally well-defined CD, that is, heptakis(2,6-di-O methyl)-CD (DIMEB), and a homologous series of surfactants, namely, n alkyl-N,N dimethyl-3 ammonio-1 propanesulfonates (SB3 x) with chain lengths ranging from x = 8 to 14...

The solvation structures of two systems rich in hydrogen and dihydrogen bonding interactions have been studied in detail experimentally through neutron diffraction with hydrogen/deuterium isotopic substitution. The results were analysed by an atomistic Monte Carlo simulation employing refinement to the experimental scattering data. The systems studied were the hydrogen storage material ammonia borane (NH3BH3, AB) dissolved in tetrahydrofuran (THF), and liquid ammonia (NH3), the latter in which AB shows unusually high solubility (260 g AB per 100 g NH3) and potential regeneration properties...

Two flavone di-C-glycosides, a pair of isomers, were isolated from Scutellaria baicalensis. The structures of compounds 1 and 2 were elucidated by means of physical data, including 1D and 2D NMR and HR-ESI-MS. Supporting theoretical calculations of the compound conformational landscape has also been conducted for geometry optimization. This is the first report of the natural occurrence of β-furanoarabinoside. In addition, the effects of compounds 1 and 2 on NO, pro-inflammatory cytokines, PGE2 and COX-2 levels were measured in lipopolysaccharide (LPS)-stimulated RAW264...
