Here, we described the outcome of thermal grafting of 2-ethynylaniline, 3-ethynylaniline and 4-ethynylaniline respectively on hydrogenated Si(100) surface. Using high resolution X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM), it was found that the grafting of these compounds could be attributed to resonating structures that arises from the position of electron donating NH2 and the electron withdrawing acetylene group. For the ortho- and para-positioned acetylene group, surface reactions were observed to proceed predominantly via the acetylene to form a Si-C bond while the meta-positioned acetylene group was found to have undergone nucleophilic grafting through the NH2 onto the silicon surface to form Si-N bond...

A series of fluorinated pyridines is investigated by ESI (tandem) mass spectrometry and quantum chemical calculations with respect to their capability to bind anions in the gas phase. The pyridines differ in valency, the degree of fluorination, the positions of the fluorine atoms, the rigidity of the spacers and the relative configuration. While the monovalent compounds did not form anion complexes, the divalent analogues exhibit anion binding even to weakly coordinating anions such as tetrafluoroborate. Three different tandem MS experiments were applied to rank the gas-phase binding energies: (i) CID experiments in an FTICR mass spectrometer, (ii) determination of the collision energy required to fragment 50 % of the mass-selected complexes, and (iii) CID of heterodimers formed from two different, competing pyridine receptors and indigo carmine, a dianion with two identical binding sites...

: Carmine is a widely used "natural" food additive that has been reported to provoke both an immediate hypersensitivity and a delayed systemic response with cutaneous expression. Systemic contact dermatitis describes the hypersensitivity reaction following systemic re-exposure of the inciting allergen in previously sensitized individuals. In individuals with recalcitrant dermatitis and a positive carmine intolerance history and/or patch test, it is important to consider a trial topical and dietary elimination of carmine-associated products and foods...

The ratio of NMR relaxation time constants T1/T2 provides a non-destructive indication of the relative surface affinities exhibited by adsorbates within liquid-saturated mesoporous catalysts. In the present work we provide supporting evidence for the existence of a quantitative relationship between such measurements and adsorption energetics. As a prototypical example with relevance to green chemical processes we examine and contrast the relaxation characteristics of primary alcohols and cyclohexane within an industrial silica catalyst support...

The presence and extent of myocardial ischemia are the major determinants of prognosis in patients with coronary artery disease (CAD). Unlike coronary angiography alone, fractional flow reserve (FFR) has enabled interventional cardiologists to accurately determine whether coronary atherosclerotic plaques are responsible for myocardial ischemia, and therefore deserve to be revascularized. Areas covered: An overview on the role of FFR in the diagnosis and treatment of coronary artery disease, as well as the potential related controversies is provided...

Muscle sympathetic nerve activity (MSNA) has shown that sympathetic activation may occur in essential hypertension (EHT). However, the small sample size of the studies, the heterogeneity of the patients examined, and the presence of confounders represented major weaknesses not allowing to draw definite conclusions. Among the 432 studies identified providing information in EHT on MSNA, 63 were eligible (1216 patients) and meta-analyzed grouping them on the basis of clinically relevant questions: (1) Is MSNA increased in hypertension of mild/moderate-to-severe degree? (2) Does sympathetic activation occur in borderline, white-coat, and masked EHT? (3) Is MSNA related to clinic and ambulatory blood pressure and target organ damage? (4) Are heart rate and venous plasma norepinephrine valuable surrogate markers of MSNA in clinical practice? The results show that MSNA was significantly greater (1...

Signal transducers and activators of transcription (STATs) mediate essential signaling pathways in different biological processes, including immune responses, hematopoiesis, and neurogenesis. Among the STAT members, STAT3 plays crucial roles in cell proliferation, survival, and differentiation. While STAT3 activation is transient in physiological conditions, STAT3 becomes persistently activated in a high percentage of solid and hematopoietic malignancies (e.g., melanoma, multiple myeloma, breast, prostate, ovarian, and colon cancers), thus contributing to malignant transformation and progression...

Fish liver is considered as a key organ that controls various life functions. The cellular and stromal elements of liver of eighteen specimens of adult grass carp were investigated by light- and electron- microscopy and enzyme histochemistry. The liver was formed of two lobes with a long process extended from the right lobe. Serial paraffin section of the liver identified different kinds of vascular- biliary structures as follows: 1) pancreatic-venous-biliary-arteriolar tracts (P-VBAT); 2) venous-biliary-arteriolar tracts, (VBAT); 3) pancreatic-venous-biliary tracts (P-VBT); 4) venous-biliary tracts (VBT); 5) venous-arteriolar tracts (VAT); 6) isolated veins named as venous tracts (VT); 7) isolated bile ducts, named as biliary tracts (BT); 8) biliary-arteriolar tracts (BAT); 9) pancreatic-biliary tracts (P-BT); 10) pancreatic- venous tracts (P-VT)...

Borş is a traditional Romanian beverage obtained by naturally fermenting an aqueous suspension of wheat bran and corn flour, used as flavoring enhancer in local gastronomy since ancient times, and more recently consumed as refreshing drink. To investigate the changes in sensory, physico-chemical, phenolic and aroma composition resulted after two successive fermentations, borș samples were subjected to standard, sensory, HPLC and GC/MS analysis. Total phenolic compounds and ferulic acid, the most abundant phenolic compound, were positively influenced by natural starter addition, increase of fermentation temperature, and thermal treatment, whereas the effect on less abundant phenolic acids was not univocal...

The lysosome is a catabolic organelle devoted to the degradation of cellular components, such as protein complexes and whole or portion of organelles that reach the lysosomes through (macro)autophagy. The lysosomes also function as signaling organelles by controlling the activity of key metabolic kinases, such as the mechanistic target of Rapamycin complex 1 (mTORC1). Lysosome dysfunction has dramatic consequences on cellular homeostasis and cause lysosomal storage disorders (LSDs). Here we review the recently proposed mechanisms by which impairment of lysosome/autophagy pathway affects extracellular matrix formation and skeletal development and growth...

G protein-coupled estrogen receptor (GPER) is an estrogen receptor expressed in the cardiovascular system. G1, a selective GPER ligand, exerts cardiovascular effects through activation of the PI3K-Akt pathway and Notch signaling in normotensive animals. Here, we investigated whether the G1/GPER interaction is involved in the limitation of infarct size, and improvement of post-ischemic contractile function in female spontaneous hypertensive rat (SHR) hearts. In this model, we also studied Notch signaling and key components of survival pathway, namely PI3K-Akt, nitric oxide synthase (NOS) and mitochondrial K+ -ATP (MitoKATP) channels...

Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor is the cornerstone of pharmacologic management of patients with acute coronary syndrome (ACS) and/or those receiving coronary stents. Long-term (>1 year) DAPT may further reduce the risk of stent thrombosis after a percutaneous coronary intervention (PCI) and may decrease the occurrence of non-stent-related ischaemic events in patients with ACS. Nevertheless, compared with aspirin alone, extended use of aspirin plus a P2Y12 receptor inhibitor may increase the risk of bleeding events that have been strongly linked to adverse outcomes including recurrent ischaemia, repeat hospitalisation and death...

Background: Oxidative stress is a recognized pathogenic mechanism in chronic obstructive pulmonary disease (COPD). Expression of the NAD+ -dependent deacetylase Sirtuin 1 (SIRT1), an antiaging molecule with a key role in oxidative stress response, has been described as decreased in the lung of COPD patients. No studies so far investigated whether systemic SIRT1 activity was associated to decreased lung function in this disease. Methods: We measured SIRT1 protein expression and activity in peripheral blood mononuclear cells (PBMCs) and total oxidative status (TOS), total antioxidant capacity (TEAC), and oxidative stress index (TOS/TEAC) in the plasma of 25 COPD patients, 20 healthy nonsmokers (HnS), and 20 healthy smokers (HS)...
