The color image of a selected segment of the ONL was converted to a grayscale image, and a MATLAB built-in function was utilized to extract the part of the image within the contour, thus extracting the image of the region of interest. Contrast-limited adaptive histogram equalization was performed to enhance the contrast of images (emphasize differences between white and nonwhite areas) and highlight the cell edges in the grayscale image. To enable separating photoreceptor nuclei from the rest of the background, the procedure converted the images into black-and-white images by designating all pixels above a threshold as white. In grayscale images, the color of each pixel was described as a number that represents a level of gray between 0 and 255 (0 corresponds to black and 255 to white). On the other hand, black-and-white images used only two color levels to describe the color of each pixel-white or black. The black-and-white (i.e., binary) picture was then filtered to remove noise pixels-all ...

Two unusual pyridones, trichodin A (1) and trichodin B (2), together with the known compound, pyridoxatin (3), were extracted from mycelia and culture broth of the marine fungus, Trichoderma sp. strain MF106 isolated from the Greenland Seas. The structures of the new compounds were characterized as an intramolecular cyclization of a pyridine basic backbone with a phenyl group. The structure and relative configuration of the new compounds were established by spectroscopic means. The new compound 1 and the known compound 3 showed antibiotic activities against the clinically relevant microorganism, Staphylococcus epidermidis, with IC50 values of 24 μM and 4 μM, respectively.

BACKGROUND: Thalassaemia major is a genetic disease characterised by a reduced ability to produce haemoglobin. Management of the resulting anaemia is through transfusions of red blood cells. Repeated transfusions result in excessive accumulation of iron in the body (iron overload), removal of which is achieved through iron chelation therapy. A commonly used iron chelator, deferiprone, has been found to be pharmacologically efficacious. However, important questions exist about the efficacy and safety of deferiprone compared to another iron chelator, desferrioxamine. OBJECTIVES: To summarise data from trials on the clinical efficacy and safety of deferiprone and to compare the clinical efficacy and safety of deferiprone for thalassaemia with desferrioxamine. SEARCH STRATEGY: We searched the Groups Haemoglobinopathies Trials Register, MEDLINE, EMBASE, Biological Abstracts, ZETOC, Current Controlled Trials and bibliographies of relevant publications. We contacted the manufacturers of deferiprone and

TY - JOUR. T1 - Thermodynamics of fluridone adsorption and desorption on three California soils. AU - Mccloskey, William B. AU - Bayer, D. E.. PY - 1987/5. Y1 - 1987/5. N2 - The thermodynamic parameters associated with fluridone [1-methyl-3-phenyl-5-[3-(trifluoromethyl)phenyl]-4(1H)-pyridinone] adsorption and desorption on three California soils were calculated from the temperature dependence of the adsorption reaction. The standard free energy change for the adsorption reaction on all three soils was negative, signifying a spontaneous reaction. The isosteric heat of adsorption and the partial molar enthalpy change indicated that van der Waals or physical forces were involved in fluridone adsorption. The enthalpy changes also showed that fluridone adsorption became weaker as the amount adsorbed increased on Yolo sandy clay loam (Typic Xerorthents) and Hesperia fine sandy loam (Typic Xerorthents) while the reverse was true on Stockton clay (not classified). Fluridone adsorption was correlated ...

Deferiprone (tradenames include Ferriprox) is a drug that chelates iron and is used to treat iron overload in thalassaemia major. It was first approved for use in treating thalassaemia major in 1994 and had been licensed for use in Europe and Asia for many years while awaiting approval in Canada and the United States. On October 14, 2011, it was approved for use in the US under the FDAs accelerated approval program. Deferiprone was at the center of a protracted struggle between Nancy Olivieri, a Canadian haematologist and researcher, and the Hospital for Sick Children and the pharmaceutical company Apotex, that started in 1996 and delayed approval of the drug in North America. Olivieris data suggested deferiprone leads to progressive hepatic fibrosis. Deferoxamine Deferasirox Savulescu, J (2004). Thalassaemia major: The murky story of deferiprone.

Inflammation serves an important role in the pathogenesis of idiopathic pulmonary fibrosis (IPF). Cannabinoid receptor 2 (CB2R) is a receptor predominantly expressed in the immune system. CB2R agonists can be used to treat a wide range of inflammation‑related diseases. Pirfenidone has been demonstrated to be effective for IPF treatment. The aim of present study was to investigate whether CB2R activation mediates the antifibrotic effect of pirfenidone. For that purpose, mice were intravenously injected with bleomycin (BLM; 5 mg/kg/day). pirfenidone (300 mg/kg/day) was then orally administered for 15 days. Lung pathological alterations in the mice were evaluated by Massons trichrome staining. The mRNA and protein levels of CB2R in lung tissues were measured by reverse transcription‑quantitative PCR and western blotting. The levels of inflammatory factors were determined by ELISA. The effect of pirfenidone on WI38 cell viability was evaluated by MTT assay. The results demonstrated that CB2R ...

IPF is a progressive disease for which two antifibrotic drugs have recently been approved, however there is an unmet need to predict responses to antifibrotic treatment, such as pirfenidone. Recent data suggested that up-regulated expression of the C-X-C chemokine-receptor type 4 (CXCR4) is indicative of outcomes in IPF.Can quantitative, molecular imaging of pulmonary CXCR4 expression as a biomarker for disease activity predict response to the targeted treatment pirfenidone and prognosis in patients with IPF?CXCR4 expression was analyzed by immunohistochemistry of lung tissues and RT-PCR of BAL. PET-CT with the specific CXCR4 ligand, gallium-68 (68Ga)-pentixafor, was performed in 28 IPF patients (PET1) and compared with baseline clinical characteristics. In 16 patients, a follow-up scan (PET2) was obtained 6-12 weeks after initiation of treatment with pirfenidone. Patients were followed in our outpatient clinic for ≥12 months.Immunohistochemistry showed high CXCR4 staining of epithelial cells ...

As part of the Distinguished Visiting Lecture series at the University of Texas Humanities Institute, Dr. Emily Greenwood gave an address where she looked at the granular level of words in the works of Aristotle.. Greenwood, chair of the Dept. of Classics at Yale, explained that philology is not merely instrumental in understanding human history: it is a study of how language makes the human. The crux of her talk was to explain a willful anti-human error in Aristotle, namely his description of slaves as an animate piece of property.. She said that Aristotle justifies this with his notorious story of human slavery. In the view of many scholars, Aristotles views on slavery are an embarrassment. In the Eudemian Ethics, Aristotle wrote a slave is as it were a member or tool of his master, a tool is a sort of inanimate slave.. This is an example, she says, showing how Aristotle uses similes and metaphors interchangeably. Here, Greenwood notes, Aristotle is relying on powerful fictions ...

FERRIPROX oral solution is a clear, reddish orange colored solution. Each mL of oral solution contains 100 mg deferiprone and the following inactive ingredients: purified water, hydroxyethylcellulose, glycerin, hydrochloric acid, artificial cherry flavor, peppermint oil, FD&C Yellow No. 6 and sucralose. FERRIPROX (deferiprone) oral solution is provided in amber polyethylene terephthalate (PET) bottles with child resistant closures (polypropylene). Each pack contains one bottle of 500 mL oral solution and a graduated measuring cup (polypropylene).. Deferiprone belongs to the class of medications called iron-chelating agents. It is used to reduce the amount of iron in the blood for people with thalassemia, when other treatments have not worked. Approval is based on a reduction in serum ferritin levels. There are no controlled trials demonstrating a direct treatment benefit, such as improvement in disease-related symptoms, functioning, or increased survival Thalassemia is a condition wherethe body ...

Mitogen-activated protein kinase (MAPK) pathway is known to be involved in the tumorigenesis of cancer cells including non-small cell lung cancer (NSCLC) and kinases involved in this pathway are frequently mutated. The development of new targeted therapies in cancer has led to the evaluation of MEK-inhibitors. Areas covered: This article reviews different studies using trametinib alone, in combination with other targeted therapies or associated with other non-targeted therapies in NSCLC, with a focus on KRAS mutant and BRAF mutant NSCLC. Expert commentary: Trametinib demonstrated activity in association with a BRAF inhibitor when BRAF was mutated. The combination of trametinib and dabrafenib has been approved for this population of BRAF mutant NSCLC patients. For KRAS mutant NSCLC, the combination of trametinib with chemotherapy has showed promising results and should be further assessed. Several clinical trials are ongoing, assessing trametinib in combination with other targeted therapies. In ...

Author(s): Jarvis, Claire L; Richers, Matthew T; Breugst, Martin; Houk, KN; Seidel, Daniel | Abstract: Secondary amines react with thiosalicylaldehydes in the presence of catalytic amounts of acetic acid to generate ring-fused N,S-acetals in redox-neutral fashion. A broad range of amines undergo α-sulfenylation, including challenging substrates such morpholine, thiomorpholine, and piperazines. Computational studies employing density functional theory indicate that acetic acid reduces the energy barriers of two separate steps, both of which involve proton transfer.

In the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial, 831 patients received apixaban 2.5 mg (with 428 patients initially randomised to this dose at baseline) based on at least two of age ≥80, bodyweight ≤60 kg, and serum creatinine ≥132.6 μmol/L.27 In a post hoc analysis on the ARISTOTLE trial data, 790 patients were treated with either apixaban 2.5 mg or warfarin; all were aged ≥75, but no additional information on indication for dose reduction or distribution of patients was given.28 In this subgroup of patients, the outcome of ischaemic stroke or systemic embolism occurred at a lower rate in the apixaban arm than in the warfarin arm (hazard ratio 0.52, 95% confidence interval 0.25 to 1.08). As no information on dose reduction was provided, direct comparisons with the results in the current study would be challenging. Even so, in the subgroup of patients with an indication for dose reduction (age ≥80 and/or renal ...

About the time that Hippocrates died, Aristotle, who may be regarded as the founder of the science of Natural History, was born (B.C. 384) in Stagira, an unimportant Hellenic colony in Thrace, near the Macedonian frontier. His father was a distinguished physician, and, like Hippocrates, boasted descent from the Asclepiadæ. The importance attached by the Asclepiads to the habit of physical observation, which has been already referred to in the life of Hippocrates, secured for Aristotle, from his earliest years, that familiarity with biological studies which is so clearly evident in many of his works.. Both parents of Aristotle died when their son was still a youth, and in consequence of this he went to reside with Proxenus, a native of Atarneus, who had settled at Stagira. Subsequently he went to Athens and joined the school of Plato. Here he remained for about twenty years, and applied himself to study with such energy that he became pre-eminent even in that distinguished band of ...

This study looks at the side effects and best dose of trametinib (targeted chemotherapy) in treating patients with cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment (advanced) with or without liver (hepatic) dysfunction. Trametinib may stop the growth of tumor cells by blocking proteins needed for cell growth. When these proteins are blocked, the growth of cancer cells may be stopped and the cancer cells will then die. Liver dysfunction is frequently found in patients with advanced cancer and usually prevents patients from receiving standard treatments or from participating in clinical trials. Patients may also need dose adjustments or absorb drugs differently. Trametinib may be a better treatment for patients with advanced cancers and liver dysfunction. ...

The safety of this drug will also be studied in both parts of ...

Taking a hint from Rob Hand s commentary, a workable sidereal perspective links Aristotles basic four qualities to the triplicities. However, Aristotle s four qualities of hot, cold, wet and dry have nothing to do with weather, temperature or seasons. They are psychological in nature. Aristotle s Basic Philosophical Principles In order to understand the four basic qualities as applied to sidereal signs, we first have to define their components according to Aristotle: Male and Female: Reflecting the society in which he lived, Aristotle elevated the rational over the passionate or emotional. Aristotle observed the female to be softer in character, more easily moved to tears, more compassionate, but also more jealous and quarrelsome. (That is, the female displays emotion!) Aristotle respected the male characteristics of courage and rationality over inferior emotional traits. Active and Passive: Aristotles Active and Passive dont resemble our contemporary astrological understanding of those ...

Aristotle ( Greek , aristotls, Aristotls 384322BC) was an ancient Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece. His father, Nicomachus, died when Aristotle was a child, whereafter Proxenus of Atarneus be

The criteria used to define marginal decline in the present study were based on the principle that selected cut-off values should facilitate rapid computation in clinical practice. The current ATS criteria for significant change do not exactly capture the reproducibility of individual indices but are a close and user-friendly approximation. However, in pharmaceutical studies in which average population effects are defined rather than change in individual patients, clinical convenience is a lesser consideration and this prompted us to explore lower threshold values for marginal decline in the hope of amplifying the outcome signal. We demonstrated that threshold values of 4, 5 and 6% provided equivalent predictive power, whereas threshold values of 3 and 7% were non-discriminatory.. These findings have implications for the selection of end-points. In therapeutic trials of pirfenidone 8 and N-acetylcysteine 7 in IPF, average treatment effects were not definitive. With pirfenidone treatment, the ...

PURPOSE To derive clinically useful information about the efficacy and tolerability of adjunctive treatment with perampanel for refractory epilepsy in an outpatient setting. METHOD We pooled retrospective casenotes data of adult patients with refractory epilepsy prescribed perampanel from 18 hospitals throughout UK and Ireland. RESULTS Three hundred and ten patients were included (mean age 40.9 [SD=12.0], 50% women, 27.7% with learning disability). The mean duration of epilepsy was 26.7 years (range 2-67 years, SD=13.5) and 91.9% were taking two or more anti-epileptic drugs at the time of perampanel initiation. Mean retention was 6.9 months (range 1 day-22.3 months, SD=4.5). The retention was 86% at 3 months, 71% at 6 months, 47.6% at 12 months and 27% at 18 months. At final follow-up a |50% reduction in seizure frequency was reached in 57.5% of tonic-clonic seizures, 57.4% of complex partial seizures and 43.8% of simple partial seizures. Eleven patients (3.5%) became seizure free. Two hundred and

The European Commission has approved apixaban (Eliquis) in the 27 countries of the European Union (EU) for the prevention of venous thromboembolic events (VTE) in adult patients who have undergone elective hip or knee replacement surgery. This decision marks the first approval for apixaban, a new oral direct Factor Xa inhibitor being developed by the alliance of Bristol-Myers Squibb and Pfizer.

Our results demonstrated that GA, induced by intravenous ketamine or inhalational sevoflurane, disturbed iron homeostasis and caused iron overload in both in vitro hippocampal neuron culture and in vivo hippocampus. Interestingly, ketamine- or sevoflurane-induced cognitive deficits, very likely, resulted from a novel iron-dependent regulated cell death, ferroptosis. Notably, iron chelator deferiprone attenuated the GA-induced mitochondrial dysfunction, ferroptosis, and further cognitive deficits. Moreover, we found that GA-induced iron overload was activated by NMDAR-RASD1 signalling via DMT1 action in the brain.. ...

conductance calcium-activated potassium channels (BKCa), iberiotoxin, and a blocker of KV7 channels, XE991. Patch clamp studies in vascular smooth muscle revealed pirfenidone increased iberiotoxin-sensitive current. In the aorta and mesenteric small arteries from diabetic db/db mice relaxations induced by the endothelium-dependent vasodilator, acetylcholine, were markedly reduced compared to db/db + mice. Pirfenidone enhanced the relaxations induced by acetylcholine in the aorta from diabetic male and female db/db mice. An opener of KV7 channels, flupirtine, had the same effect as pirfenidone. XE991 reduced the effect of pirfenidone and flupirtine and further reduced acetylcholine relaxations in the aorta. In the presence of iberiotoxin, pirfenidone ...

RESULTS: Three trials meeting inclusion criteria were identified. Direct comparison between apixaban 2.5 mg twice daily (BID) versus apixaban 5 mg BID showed no difference for any outcome. Clinically relevant non-major bleeding occurred less with both apixaban 2.5 mg BID (OR 0.23, 95% CI 0.08-0.62, P=0.004) and apixaban 5 mg BID [OR 0.31, 95% CI 0.11-0.82, P=0.019] compared to rivaroxaban 20 mg daily. Apixaban 2.5 mg BID showed less clinically relevant non-major bleeding than dabigatran 150 mg BID [OR 0.4, 95% CI 0.16-0.9, P=0.04], but not apixaban 5 mg BID. There were no differences between rivaroxaban 20 mg daily and dabigatran 150 mg BID. No differences in risk for recurrent VTE, major bleeding, or mortality were observed for any comparison between any pair of NOACs ...

Current clinical practice guidelines for idiopathic pulmonary fibrosis (IPF) conditionally recommend use of pirfenidone and nintedanib. However, an optimal treatment sequence has not been established, and the data of treatment sequence from pirfenidone to nintedanib are limited. This study aimed to evaluate safety, tolerability and efficacy of nintedanib switched from pirfenidone in patients with IPF. Thirty consecutive IPF cases, which discontinued pirfenidone because of a decline in forced vital capacity (FVC) or intolerable adverse event (AE), and newly started nintedanib (150 mg twice daily) from September 2015 to August 2017 (switch-group) were retrospectively reviewed. Subsequently, we compared the characteristics, treatment status, and AEs between the switch-group and other 64 IPF patients newly started nintedanib during the same period without any prior anti-fibrotic treatment (pirfenidone-naïve group). In the switch group, median age, body weight, body mass index (BMI), and %FVC were 72 years

Aristotle 1495 vol 1.. Aristotles Organon was, as Aldus reminded Alberto Pio (1475-1531), Prince of Carpi, who had sponsored its printing, the vital key to unlocking knowledge. It was the basic text used at medieval universities and would certainly have been used by Aldus when instructing Pio when he was the latters tutor at Carpi. Many Latin translations of works by Aristotle (and his commentators) had been printed previously, but in the late fifteenth century an edition of Aristotle in the original Greek, shorn of its medieval interpretative baggage, was a desideratum for humanists throughout Europe. To meet this challenge, Aldus formed a group of editors, the learned men in Venice and Padua. These included international scholars such as the renowned English scholar, Thomas Linacre (1460-1524), part of the English wing of Aldus nascent Republic of Letters, and, closer to home, the Pistoiese humanist Scipione Forteguerra (1466-1515). A prefatory letter from the latter to those pursuing ...

Introduction The direct oral anti-coagulants (DOAC) edoxaban and rivaroxaban are suggested treatment alternatives for cancer associated venous thromboembolism (VTE) together with low molecular-weight heparins. New studies indicate that the DOAC apixaban also is an option for cancer-associated VTE. The current study assessed recurrent VTE, arterial thrombosis, bleedings and adverse events in a cohort of apixaban treated cancer patients with VTE. Materials and Methods Single-arm, interventional study of apixaban as treatment of cancer-associated VTE. Inclusion criteria were cancer with objectively verified VTE. Patients received apixaban 10 mg bid for seven days, then 5 mg bid for six months. Primary efficacy and safety outcomes were recurrent VTE and bleeding respectively. This trial is registered with ClinicalTrials.gov identifier NCT02581176. Results We recruited 298 cancer patients with VTE. During six months treatment, recurrent VTE or death related to VTE occurred in 12 patients (4.0%, 95% ...

This book is about Aristotles account of time in Physics IV.10-14. Aristotle claims that time is not a kind of change, but that it is something dependent on change. He defines it as a kind of number of change with respect to the before and after. It is argued that this means that time is a kind of order (not, as is commonly supposed, that it is a kind of measure). It is a universal order within which all changes are related to each other. This interpretation is used to explain two puzzling claims that Aristotle makes: that the now is like a moving thing, and that time depends for its existence on the soul.

There has possibly been exageration of the Muslim role in transmitting the Greek philosophers to the West, and if that were the only point being made here then fine. However it clearly is not, and there is significant exaggeration happening in the other direction. Anyone who would claim that Aristotles texts came to the West only indirectly would of course be spouting nonsense but who claims that? This is a straw man. What is being ignored here though is that Plato was virtually unknown, and that Europeans themselves, both those for and against Greek learning, clearly associated it with Averroes and Avicenna and the like. Their influence triggered an enormous change in the way in which Aristotle was studied in Europe. Previously Aristotle was known, but in a very filtered understanding. To try to imply that the revolutionary Aristotelianism of Thomas Aquinas and Albertus Magnus is not something which was heavily based upon Moslem interpretations would be nonsense. You just have to read the ...

Aristotle begins the Nicomachean Ethics by asking what the final good for human beings is. He identifies this final good with happiness, and in the rest of Book I, asks what happiness is. In I 7, Aristotle reaches an outline of an answer, claiming that the human good (that is, happiness) is activity of the soul in ...

Apixaban is a fresh dental anticoagulant with a particular inhibitory actions on FXa. and platelet relationships with broken vascular areas in perfusion research (p 0.05 and p 0.01, respectively). Impairments in fibrin development had been normalized by the various concentrates. Just rFVIIa considerably restored degrees of platelet deposition. Modifications in hemostasis induced by apixaban had been variably paid out by the various factor concentrates looked into. However, ramifications of these concentrates werent homogeneous in every the assessments, with PCCs displaying more effectiveness in TG, and rFVIIa becoming far better on TEM and perfusion research. Our outcomes indicate that rFVIIa, PCCs and aPCCs possess the potential to revive platelet and fibrin the different parts of the hemostasis previously changed by apixaban. Launch Regardless of the better protection profile of recently developed dental anticoagulants, blood loss continues to be a protection concern and reversal of their ...

Apixaban is a potent, oral, reversible, direct and highly selective active site inhibitor of factor Xa. It does not require antithrombin III for antithrombotic activity. Apixaban inhibits free and clot-bound factor Xa, and prothrombinase activity. By inhibiting factor Xa, apixaban prevents thrombin generation and thrombus development.

Early in 2018 a book Aristote et Thomas dAquin: les commentaires sur les œuvres majeures dAristote (Les Presses Universitaires de lIPC 2018; publication is available also at Amazon), by Leo Elders (whose other publication, Thomas Aquinas and His Predecessors, was recently discussed at our website). This book is devoted to Aquinas twelve commentaries on Aristotles works. Elders strives to determine whether St. Thomas reported Aristotles thought faithfully or whether his interpretations were permeated by his own theological approach and influenced by the quality of the translations of Aristotles works that were in use at that time.. Elders has been conducting research on Aristotle since the 1960s, later he also began to analyse Aristotles influence on Aquinas theology and philosophy. You may find several of his papers on this topic online:. ...

The history of computers is often told as a history of objects, from the abacus to the Babbage engine up through the code-breaking machines of World War II. In fact, it is better understood as a history of ideas, mainly ideas that emerged from mathematical logic, an obscure and cult-like discipline that first developed in the 19th century. Mathematical logic was pioneered by philosopher-mathematicians, most notably George Boole and Gottlob Frege, who were themselves inspired by Leibnizs dream of a universal concept language, and the ancient logical system of Aristotle ...
