Reproducibility of Skin Temperature Response after Cold Stress Test Using the Game Ready System: Preliminary Study
2021
The objective of this preliminary study was to determine the reproducibility of lower limbs skin temperature after cold stress test using the Game Ready system. Skin temperature of fourteen participants was measured before and after cold stress test using the Game Ready system and it was repeated the protocol in four times: at 9:00, at 11:00, at 19:00, and at 9:00 h of the posterior day. To assess skin temperature recovery after cold stress test, a logarithmic equation for each region was calculated, and constant (β0) and slope (β1) coefficients were obtained. Intraclass correlation coefficient (ICC), standard error (SE), and within-subject coefficient of variation (CV) were determined. No …
Four color-measuring devices compared with a spectrophotometric reference system
2009
Abstract Objectives The objective of this study was to compare the L*C*h° color coordinates of dental color-measuring devices with those of a spectrophotometric reference system. Methods The International Commission on Illumination (CIE) L*C*h° color coordinates of ceramic samples, matching the colors of the VITA Linearguide, were recorded using four color-measuring devices (VITA Easyshade (A), VITA Easyshade compact (B), Degudent Shadepilot (C), X-Rite Shadevision (D)) and a spectrophotometric reference system under standardized test conditions. The intraclass correlation coefficients, regression lines with coefficients of determination, and mean deviations of the dental color-measuring de…
Dependence of T-lymphocyte activation on the extent of cellular damage
2010
Mechanically damaged cells release intracellular substances, resulting in the activation of CD4- and CD8-positive T-lymphocytes. The goal of this investigation was to quantify and compare fractions of activated CD4- and CD8-positive T-lymphocytes, based on the quantity of damaged cells in a given blood sample. Blood samples were mechanically stressed by vortexing intensely. Subsequently, different quantities of distressed blood samples were mixed with samples of fresh, whole blood. Afterwards, the extent of CD4- and CD8-positive T-cell activation was examined in the mixture by flow cytometry. Sine-like curves of T-cell activation were observed for both CD4- (T-helper mediated) and CD8- (cyt…
Monoclonal antibody TeM 106 reacts with a tonoplast intrinsic protein of 106 kDa from Brassica oleracea L
1995
A monoclonal antibody, designated TeM 106, that recognizes an intrinsic protein from the vacuole membrane (tonoplast) of cauliflower (Brassica oleracea L. var. botrytis) is described. Mice were immunized with a tonoplast fraction that had been purified from differentiating meristematic cells from the cauliflower head. Hybridomas were generated and screened by means of Enzyme Linked Immuno Sorbent Assays for differential reactivity to tonoplast over non-related proteins (bovine serum albumin). One out of 14 reactive murine clones was selected on the basis of its stability, secretory efficiency, and high affinity of the secreted antibodies. TeM 106 is an IgM which was shown by indirect immuno…
Analysis of liver-specific protein LSP using murine monoclonal antibodies.
1987
. We describe twenty murine monoclonal antibodies directed against different antigenic determinants of human and rabbit liver-specific protein LSP. Among them, nine were directed against liver-specific epitopes as judged from immunohistological studies. Immunoelectronmicroscopy revealed that seven of these monoclonals recognized membrane determinants differing in staining of distinct areas of the hepatocellular surface. Eleven antibodies were directed against intracellular structures. Western blot analysis showed that the epitopes detected were displayed on either single or multiple protein bands with apparent molecular weights between 24 000 and 60 000. Further differences were observed wi…
Role of Hemodynamic Forces in Unruptured Intracranial Aneurysms: An Overview of a Complex Scenario.
2017
Background An understanding of the natural history of unruptured intracranial aneurysms (IAs) has always played a critical role in presurgical or endovascular planning, to avoid possibly fatal events. Size, shape, morphology, and location are known risk factors for rupture of an aneurysm, but morphologic parameters alone may not be sufficient to perform proper rupture risk stratification. Methods We performed a systematic PubMed search and focused on hemodynamics forces that may influence aneurysmal initiation, growth, and rupture. Results We included 223 studies describing several hemodynamic parameters related to aneurysm natural history. In these studies, different modalities of aneurysm…
Stimulation with carbachol alters endomembrane distribution and plasma membrane expression of intracellular proteins in lacrimal acinar cells.
2000
The events that lead to Sjogren's autoimmune processes in the lacrimal gland remain poorly understood. The acinar cell's responses to acute cholinergic stimulation include release of secretory products across the apical plasma membrane (apm) and a number of processes related to traffic between endomembrane compartments and the basal-lateral plasma membranes (blm), such as recruitment of Na, K-ATPase, accelerated recycling, and accelerated transcytosis of secretory IgA. We tested the hypothesis that stimulation-induced acceleration of endomembrane traffic is accompanied by changes in compartmentation and increased blm expression of proteins that are normally sequestered in endomembrane compa…
Inhibition of Delta-like 4 mediated signaling induces abortion in mice due to deregulation of decidual angiogenesis.
2013
Objective: To explore whether the Dll4/Notch1 pathway plays a key role in regulating the vascular endothelial growth factor (VEGF)/VEGF receptor 2 (VEGFR2) driven decidual angiogenesis and related pregnancy through induction of a tip/stalk phenotype. Methods: Progesterone-replaced ovariectomized pregnant mice received a single injection of YW152F (Dll4 blocking antibody, BAb) or placebo at embryonic day (E) 4.5. Animals were sacrificed at different time points; blood and uterus were collected for further analysis. Number of embryos and implantation site, uteri weight, and serum progesterone levels were assessed. Alterations in the tip/stalk phenotype were determined by quantitative immunofl…
Flußquantifizierung von intrakardialen Shuntvolumina unter Verwendung der MR-Phasenkontrast-Technik in Atemanhaltephase
1998
PURPOSE Comparison of a breath-hold, velocity-encoded, phase-difference magnetic resonance (MR) sequence for intracardiac shunt flow measurement with the invasive shunt size determination by oximetry. PATIENTS AND METHODS 10 patients with different cardiac shunts (6 ASD/3 VSD/1 PDA) and four healthy individuals were investigated using a 1.5 Tesla Siemens Vision system. For flow measurements a breath-hold, velocity-encoded, phase-difference magnetic resonance (MR) sequence was used ('through plane', FLASH 2D-sequence, TR/TE 110/5 ms, 'velocity encoding' 250 cm/s). Mean flow (ml/R-R interval) in the ascending aorta, the pulmonary trunk, and the right and left pulmonary arteries was determined…
Concept and Treatment of Hydrocephalus in the Greco-Roman and Early Arabic Medicine
2007
In the ancient medical literature hydrocephalus was not often described although its existence and symptomatology were well known. Most detailed descriptions of hydrocephalus including the surgical treatment are extant in the encyclopaedic works on medicine of the physicians Oreibasios and Aetios from Amida from the 4th and 6th centuries AD, respectively. Because of their broad scientific interests, this type of physicians, typical for the late Roman empire, were known as philosophy-physicians (iota alpha tau rho o sigma o phi iota sigma tau alpha iota). They defined hydrocephalus in contrast to our present understanding as a fluid collection excluding abscesses visible as a bulging tumour …
