Parkinson's disease (PD) is a neurodegenerative condition featured by motor dysfunction, death of midbrain dopaminergic neurons and accumulation α-synuclein (αSyn) aggregates. Growing evidence suggests that PD diagnosis happens late in the progression pathology may originate much earlier enteric nervous system (ENS) before advancing to brain, via autonomic fibers. It was recently described specific cell type from gut epithelium named enteroendocrine cells (EECs) possess many neuron-like...
Synopsis The aim of this work was to evaluate the correlation between in vitro and vivo determinations sun protection factors (SPF) sunscreen lotions containing synthetic octyl methoxycinnamate. Three either 2, 4.5 or 7.5% methoxycinnamate were prepared. SPFs these determined according spectrophotometric method Mansur et al. SPF values Food Drug Administration (FDA) method. results indicate that there a good for examined.
Genome-wide profiling of rare tumors is crucial for improvement diagnosis, treatment, and, consequently, achieving better outcomes. Desmoplastic small round cell tumor (DSRCT) a type sarcoma arising from mesenchymal cells abdominal peritoneum that usually develops in male adolescents and young adults. A specific translocation, t(11;22)(p13;q12), resulting EWS WT1 gene fusion the only recurrent molecular hallmark no other genetic factor has been associated to this aggressive tumor. Here, we...
Redox-related plasma proteins are candidate reporters of protein signatures associated with endothelial structure/function. Thiol-proteins from disulfide isomerase (PDI) family unexplored in this context. Here, we investigate the occurrence and physiological significance a circulating pool PDI healthy humans. We validated an assay for detecting individuals. Our results indicate high inter-individual (median = 330 pg/mL) but low intra-individual variability over time repeated measurements....
We compared the impregnation techniques for globules according to Manual of Technical Norms Homeopathic Pharmacies (MNTFH) Association Pharmacists (ABFH), Brazilian Pharmacopoeia (FHB) and variations these techniques. The variables were evaluated in this procedure, three different sizes (N o . 3, 5 7), hydroalcoholic solution 70% (v/v) Minoxidil 2% (w/v) was used impregnate concentrations 2, 4, 5% (v/w) at 10 %(v/w) solutions 70, 80 90% (v/v), four various ( A -glass, B -paper, C -cup D...
A characterization of the magnetic superconductors RuSr2GdCu2O8 [Ru-(1212)] and RuSr2(Gd1.5Ce0.5)Cu2O10 [Ru-(1222)] through resistance measurements as a function temperature field is presented. Two peaks in derivative resistive curves are identified intra- intergrain superconducting transitions. Strong intragrain granularity effects observed, explained by considering antiphase boundaries between structural domains coherently rotated RuO6 octahedra Josephson-junctions. different dependence...
The monoclinic double perovskite Sr2YRuO6 has recently gained a renewed interest in order to get deeper insight into the exotic magnetic ground states associated with geometric frustration. Striking discrepancies between spin derived from neutron diffraction refinements and macroscopic thermal responses is major challenge that must be addressed. In this work, detailed measurements as function of temperature yield completely different interpretation patterns. We show at low temperatures...
The most common way to perform succussions is place a liquid preparation inside glass vessel and beat it vigorously against hard elastic surface, either manually or using mechanical apparatus. This procedure has been assumed able transfer energy the molecular level, where becomes available chemical work. Such interpretation enforced by observed changes in electrical conductivity (EC) of High Dilutions (HD) due succussion. In order address this question, we compared HD prepared from...
Among double perovskites, the interpretation of magnetic, thermal and transport properties Sr2YRuO6 remains a challenge. Characterization using different techniques reveals variety features that are not understood, described as anomalous, yields contradictory values for several relevant parameters. We solved this situation through detailed susceptibility, specific heat, expansion x-ray diffraction measurements, including quantitative correlation parameters characterizing so-called anomalies....
Abstract There is a constant interest in blood‐based protein biomarkers, which can help to improve diagnosis and treatment outcomes of multifactorial human pathologies. In this regard, proteomic studies usually employ plasma immunoaffinity fractionation deplete the most abundant proteins, due high dynamic concentration range proteins. The depletion proteins allows obtain less and, oftentimes, more interesting However, removal fraction ‐ depletome may co‐elute many unintended protein‐protein...
Amylin is a pancreatic hormone involved in the regulation of glucose metabolism and homeostasis. Restoration post-prandial basal levels human amylin diabetic individuals key controlling glycemia, glucagon, reducing insulin dose increasing satiety, among other physiologic functions. Human has high propensity to aggregate. We have addressed this issue by designing liposomal formulation. Nanoparticles multilamellar liposomes comprising were obtained with 53% encapsulation efficiency. The vitro...
