Curcumin was complexed with β-CD using co-precipitation, freeze-drying and solvent evaporation methods. Co-precipitation enabled complex formation, as indicated by the FT-IR FT-Raman techniques via shifts in peaks that were assigned to aromatic rings of curcumin. In addition, photoacoustic spectroscopy X-ray diffraction, disappearance band related rings, Gaussian fitting, modifications spectral lines, respectively, also suggested formation. The possible complexation had an efficiency 74%...
Peripheral arterial disease (PAD) is a threatening complication of diabetes. As endothelial progenitor cells (EPCs) are involved in neovasculogenesis and maintenance vascular homeostasis, their impairment may have role the pathogenesis diabetic vasculopathy. This study aimed to establish whether number function EPCs correlate with PAD severity type 2 patients.EPCs were defined by expression CD34, CD133 KDR, quantified flow cytometry 127 patients without PAD. has been assessed as carotid...
Disruption of the endothelial layer is first step in atherogenic process. Experimental studies have shown that progenitor cells (EPCs) are involved homeostasis and repair. Conversely, EPC depletion has been demonstrated setting established atherosclerotic diseases. With this background, we evaluated whether variations number EPCs associated with subclinical atherosclerosis healthy subjects.Carotid intima-media thickness (IMT), high-sensitive C-reactive protein (hsCRP), levels circulating...
The time-resolved and steady-state mode-mismatched thermal lens technique has been used to determine the temperature coefficient of optical path length ds/dT at different wavelengths soda lime glasses (72 wt % SiO2, 18 Na2O, 10 CaO, 70.5 17.5 2 Fe2O3). aberrant model, which takes into account thickness change sample is more realistic than parabolic treatment when describe effect, was as theoretical model. results showed that (2.1±0.1)×10−6 K−1 632.8 nm (2.4±0.1)×10−6 442 for undoped...
Endothelial progenitor cells (EPCs) participate in vascular homeostasis and angiogenesis. The aim of the present study was to explore EPC number function relation cardiovascular risk, gender, reproductive state.As measured by flow-cytometry 210 healthy subjects, CD34(+)KDR(+) EPCs were higher fertile women than men, but not different between postmenopausal age-matched men. These gender gradients mirrored differences profile, carotid intima-media thickness, brachial artery flow-mediated...
Abstract The effect of radiation forces at the interface between dielectric materials has been a long-standing debate for over century. Yet there so far only limited experimental verification in complete accordance with theory. Here we measure surface deformation air–water induced by continuous and pulsed laser excitation match this to rigorous theory forces. We demonstrate that results are quantitatively described numerical calculations Helmholtz force is used pressure. resulting pressure...
Safranine-O (Sf) is a photosensitizer (PS) displaying remarkable potential for photodynamic therapy (PDT). In this work, we have used the combination of Sf with F127 Pluronic and Carbopol (C934P) to obtain stimuli-responsive hydrogel (SR-Sf). This thermoresponsive-photoactive nanostructured system was prepared by two different methods: direct addition (DA) solid dispersion (SD). Both SR-Sf had their physical chemical properties evaluated veterinary applications, especially considering...
Patients with chronic severe lung disease are prone to develop pulmonary vascular remodeling, possibly through endothelial dysfunction. Circulating progenitor cells (EPCs) involved in maintenance of homeostasis. The aim this study was assess whether obstructive and restrictive diseases associated modification EPC number peripheral blood. cross-sectional patients (n = 15) on oxygen therapy 15 control subjects. EPCs were defined by the surface expression CD34, CD133, kinase-insert domain...
OBJECTIVE The loss of myenteric neurons in the lower esophageal sphincter (LES) characterizes achalasia, an motor disorder. Because presence lymphocytic infiltrates suggests immuno-mediated mechanism ongoing at sites disease, we investigated T-cell receptor (TCR) repertoire and ability to recognize human herpes virus type 1 (HSV-1) antigens LES-infiltrating T lymphocytes achalasia patients. METHODS Fifty-nine patients with idiopathic 38 heart-beating cadaveric multiorgan donors (controls)...
The purpose of the present work was to investigate possible inhibitory effect a pinhão coat extract rich in condensed tannin on activity α-amylases (human salivary and porcine pancreatic). Experiments with classic α-amylase inhibitor acarbose from Acacia mearnsii were done for comparative purposes. Fourier transform-infrared spectroscopy analysis revealed higher proportion procyanidins prodelphinidins when compared A. tannin. an effective both human pancreatic α-amylase. Inhibition mixed...
An absolute thermal lens method to determine fluorescence quantum efficiency and concentration quenching of solids is described in this work. The low silica calcium aluminate glasses doped with different concentrations neodymium dioxide melted under vacuum conditions remove water has been measured by using mode-mismatched spectrometry. It shown that the signal amplitude linearly dependent on up 4.0 wt %, changing significantly from 4.5 5.0 indicating there was only above % dioxide....
Purpose: The chronic exposure at high altitude (HA) represents an ideal model for evaluating the in vivo effects of hypobaric hypoxia. Taking advantage EV-K2-CNR Pyramid, this study was designed to evaluate whether acute and hypoxia differently modulates immune responses. Methods: includes 13 healthy female moderately active volunteers participating Italian HA project EV-K2-CNR. Peripheral blood lymphocytes, collected sea level Pyramid Laboratory CNR, Nepal (5050 m), were immunologically...
An unexplained paradox puzzles diabetologists: diabetic patients must face both poor vessel growth in ischemic heart and limbs increased angiogenesis retinal complications (1,2). Endothelial progenitor cells (EPCs) are marrow-derived involved adult neovascularization endothelial homeostasis (3,4). It has been postulated that low EPCs peripheral blood may have a role cardiovascular disease, we demonstrated reduced macrovascular diabetes (5,6). On the other hand, an excess of be pathologic...
Conventional thermal lens spectrometry theory assumes that the sample is an infinite medium, and only radial temperature rise heat flow in are considered. This approach not suitable for thin-film samples. Considering axial boundary conditions of sample, a three-dimensional model cw laser-induced mode-mismatched presented. However, its mathematical expression so convenient as conventional to deal with experimental data. The shows that, besides ratio excitation laser spot size thickness ωe/l...
