BACKGROUND: In the emergency setting, non-traumatic headache is a benign symptom in 80% of cases, but serious underlying conditions need to be ruled out. Copeptin improves risk stratification in several acute diseases. Herein, we investigated the value of copeptin to discriminate between serious secondary headache and benign headache forms in the emergency setting. METHODS: Patients presenting with acute non-traumatic headache were prospectively enrolled into an observational cohort study...

BACKGROUND: Antibody-dependent cell-mediated cytotoxicity (ADCC) may contribute to the antitumor activity of cetuximab. However, the extent of this contribution is unclear. In this study, we investigated the impact of baseline ADCC on the outcome of patients with locally advanced squamous cell carcinoma treated with cetuximab and radiotherapy. METHODS: We determined baseline ADCC in 28 patients treated with cetuximab and radiotherapy and in 15 patients treated with chemoradiation...

Parkinsonian-like state was generated in mice by the administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to study the effects of Atremorine in Parkinson's disease (PD) related neuropathology and behavior deficits. This devastating disease is caused by the progressive degeneration of dopaminergic neurons in the substantia nigra. Numerous therapeutic strategies have been developed to protect neuronal damage, although no effective treatment for PD has been validated yet. This study tested the preventive and therapeutic neuroprotective effect of Atremorine on MPTP parkinsonian mouse model...

BACKGROUND: In plants carotenoids play an important role in the photosynthetic process and photo-oxidative protection, and are the substrate for the synthesis of abscisic acid and strigolactones. In addition to their protective role as antioxidants and precursors of vitamin A, in wheat carotenoids are important as they influence the colour (whiteness vs. yellowness) of the grain. Understanding the genetic basis of grain yellow pigments, and identifying associated markers provide the basis for improving wheat quality by molecular breeding...

High quality thin insulating films on graphene (Gr) are essential for field effect transistors (FETs) and other electronics applications of this material. Atomic Layer Deposition (ALD) is the method of choice to deposit high-κ dielectrics with excellent thickness uniformity and conformal coverage. However, to start the growth on the sp(2) Gr surface a chemical pre-functionalization or the physical deposition of a seed layer are required, which can effect, to some extent, the electrical properties of Gr. In this paper we report a detailed morphological, structural and electrical investigation of Al2O3 thin films grown by a two-steps ALD process on large area Gr membranes residing on an Al2O3/Si substrate...

Antipsychotic drugs are currently used in clinical practice for a variety of mental disorders. Among them, clozapine is the most effective medication for treatment-resistant schizophrenia and is most helpful in controlling aggression and the suicidal behavior in schizophrenia and schizoaffective disorder. Although clozapine is associated with a low likelihood of extrapyramidal symptoms and other neurological side effects, it is well-known for the weight gain and metabolic side effects, which expose the patient to a greater risk of cardiovascular disorders, premature death, as well as psychosocial issues leading to non-adherence to therapy...

The five-factor model (FFM) is a widely used taxonomy of human personality; yet its neuro anatomical basis remains unclear. This is partly because past associations between gray-matter volume and FFM were driven by different surface-based morphometry (SBM) indices (i.e. cortical thickness, surface area, cortical folding or any combination of them). To overcome this limitation, we used Free-Surfer to study how variability in SBM measures was related to the FFM in n = 507 participants from the Human Connectome Project...

Recently, several cases of symptomatic, sometimes fatal bradycardia during the first days of direct-acting antiviral (DAA) (eg, sofosbuvir [SOF]) administration have been reported. We analyzed in detail electrocardiographic (ECG) changes during SOF- or non-SOF-based chronic hepatitis C (CHC) treatment, specifically focusing on bradyarrhythmias. All 39 consecutive patients treated at our center with any interferon-free regimen between June and December 2015 were included in this study (26 SOF-based therapy vs 13 no-SOF interferon-free regimens)...

The influence of obesity on development, severity and prognosis of both asthma and COPD is attracting growing interest. The impact of obesity on the respiratory system ranges from structural modifications (decline of total lung capacity) to humoral alterations. Adipose tissue strongly contributes to the establishment of an inflammatory state being an important source of adipokines. Amongst adipokines, adiponectin is an important component of organ cross talk with adipose tissue exerting protective effects on a variety of pathophysiological processes...

BACKGROUND: While the use of antibiotic prophylaxis is clearly advantageous to prevent streptococcal infection, it alters the composition of the gut microbiota in mothers and infants. Enterococcus faecium L3 is one of the best studied probiotic strains and shows strong antagonistic activity against Streptococcus agalactiae due to the production of bacteriocins able to inhibit common gut and vaginal pathogens. METHODS: We tested an L3-based probiotic formula (iNatal®) on 127 pregnant women attending our gynaecological unit in 2015...

The highly reactive dicarbonyl methylglyoxal (MGO) is mainly formed as byproduct of glycolysis. Therefore, high blood glucose levels determine increased MGO accumulation. Nonetheless, MGO levels are also increased as consequence of the ineffective action of its main detoxification pathway, the glyoxalase system, of which glyoxalase 1 (Glo1) is the rate-limiting enzyme. Indeed, a physiological decrease of Glo1 transcription and activity occurs not only in chronic hyperglycaemia but also with ageing, during which MGO accumulation occurs...

In early mouse pre-implantation development, primitive endoderm (PrE) precursors are platelet-derived growth factor receptor alpha (PDGFRα) positive. Here, we demonstrated that cultured mouse embryonic stem cells (mESCs) express PDGFRα heterogeneously, fluctuating between a PDGFRα+ (PrE-primed) and a platelet endothelial cell adhesion molecule 1 (PECAM1)-positive state (epiblast-primed). The two surface markers can be co-detected on a third subpopulation, expressing epiblast and PrE determinants (double-positive)...

'Privileged scaffolds' are molecular frameworks which have been successfully exploited for small molecule drug discovery. Peptide privileged scaffolds, featuring a strictly conserved multiple-disulfide framework and high variability in the rest of the sequence, display a broad range of biological effects, including antimicrobial and antiviral activity. Unlike small molecules, however, the cost of manufacturing these peptides is high, and their synthesis challenging. We previously described a simplified privileged scaffold corresponding to the γ-core of human β-defensin-3 (HBD3)...

The filamentous Cyanobacterium Arthrospira is commercially produced and is a functional, high-value, health food. We identified 5 low temperature and low light intensity tolerant strains of Arthrospira sp. (GMPA1, GMPA7, GMPB1, GMPC1, and GMPC3) using ethyl methanesulfonate mutagenesis and low temperature screening. The 5 Arthrospira strains grew rapidly below 14 °C, 43.75 μmol photons m(-2) s(-1) and performed breed conservation at 2.5 °C, 8.75 μmol photons m(-2) s(-1). We used morphological identification and molecular genetic analysis to identify GMPA1, GMPA7, GMPB1 and GMPC1 as Arthrospira platensis, while GMPC3 was identified as Arthrospira maxima...

The intestinal epithelium is continuously renewed by intestinal epithelial stem cells (IESCs) positioned at the base of each crypt. Mesenchymal-derived factors are essential to maintain IESCs; however, the cellular composition and development of such mesenchymal niche remains unclear. Here, we identify pericryptal CD34(+) Gp38(+) αSMA(-) mesenchymal cells closely associated with Lgr5(+) IESCs. We demonstrate that CD34(+) Gp38(+) cells are the major intestinal producers of the niche factors Wnt2b, Gremlin1, and R-spondin1, and are sufficient to promote maintenance of Lgr5(+) IESCs in intestinal organoids, an effect mainly mediated by Gremlin1...

OBJECTIVES: Patients receiving glucocorticoid treatment are prone to develop metabolic complications. In preclinical studies, metformin prevented the development of the metabolic syndrome during glucocorticoid excess. We herein investigated the metabolic effect of metformin during glucocorticoid treatment in non-diabetic patients. METHODS: In a double-blind, placebo-controlled trial, patients starting glucocorticoid treatment (prednisone, prednisolone or methylprednisolone) for four weeks were randomised to concomitantly receive metformin (850 mg once daily for one week followed by 850 mg twice daily for three weeks) or placebo...

BACKGROUND: Minimal access surgery for incisional hernia repair is still debated, especially for giant wall defects. Laparoscopic repair may reduce pain and hospital stay. This study was designed to evaluate the feasibility of the laparoscopic technique in giant hernia. MATERIALS AND METHODS: From 2007 to 2013, 35 consecutive patients with giant ventral hernia, according to the Chevrel classification, underwent laparoscopic repair. Fourteen patients were obese, with a body mass index (BMI) > 30 and in 21 patients the mean BMI was 24 (range 22-28)...
