Markovica investīciju portfeļu izveide un analīze

2019

Investēšana akcijās ir ļoti sena un pazīstama investēšanas stratēģija un šī darba ietvaros tiek parādīts, kura investēšanas stratēģija veidojot efektīvu Markovica portfeli nodrošina vislabāko riska un ienesīguma attiecību. Maģistra darba mērķis ir, balstoties uz zinātniskās literatūras un uzņēmumu akcijas analīzi, izveidot trīs diversificētus un efektīvus akciju portfeļus pēc Markovica investīciju portfeļa stratēģijas (B. Grema, Dž. Piotroski un Dž. Grīnblata) un noteikt labāko portfeli pēc riska un ienesīguma attiecības. Darba autors veica B. Grema, Dž. Piotroski un Dž. Grīnblata stratēģiju izpēti un pēc tās atlasīja akcijas ieguldījumu portfelī. Analizējot katru stratēģiju un izvērtējot t…

Toward an International Curricula Network for exchanges and LifeLong Learning

2010

4 pages; International audience; During the last years, an important work has been achieved within the framework of the European programs in order to emphasize and allow the mobility of students, the exchange of teachers, the recognition of diploma (programs ERASMUS, now in the LLP program)... These reflections have been done for classical programs within HEIs throughout Europe and also within the programs dedicated to vocational studies (LEONARDO, ValeurTech, EQF) to emphasize Life Long Learning and credit accumulation all around the life, with an approach based on competences [1]. The main purposes in these programs can be summarized as follows: − Favoring the equality among citizens in E…

Electrochemical treatment of paper mill wastewater by electro-Fenton process

2019

Abstract The electrochemical oxidation of organics in paper mill wastewater belonging to Halfa industries (Tunisia) was performed by galvanostatic electrolyses using electro-Fenton (EF) process. The effect of several operating parameters, such as applied current density, electrodes material, air pressure and the presence of sodium chloride (NaCl) was evaluated. In particular, carbon felt (CF), modified carbon felt (MCF) and gas diffusion electrode (GDE) were used as cathode while Ti/IrO2-Ta2O5 and Boron Doped Diamond (BDD) as anode. Total Organic Carbon (TOC) measure was chosen as reference parameter to assess the extent of the treatment. The experimental results show that, by adopting the …

Metabolic Profile in a Cohort of Young Sicilian Patients with Klinefelter’s Syndrome: The Role of Irisin

2022

Klinefelter’s syndrome (KS) is the main cause of hypogonadism and infertility in men and is often related to obesity, metabolic syndrome, and diabetes. The purpose of our real-life observational study was to investigate the metabolic and anthropometric parameters in a population of patients with Klinefelter syndrome compared to a group of healthy age-matched subjects. Methods. In our study, 25 consecutive Caucasian adult outpatients (age range 21–52 years, mean age 32.9 ± 12.2) with KS in testosterone replacement therapy and 30 healthy men (age range 25–45 years, mean age 32.4 ± 7.62) were studied. In both groups of subjects, anthropometric indices, lipid profile, glucose metabolic paramete…

Trafficking of the human transferrin receptor in plant cells: effects of tyrphostin A23 and brefeldin A.

2006

Plant cells possess much of the molecular machinery necessary for receptor-mediated endocytosis (RME), but this process still awaits detailed characterization. In order to identify a reliable and well-characterized marker to investigate RME in plant cells, we have expressed the human transferrin receptor (hTfR) in Arabidopsis protoplasts. We have found that hTfR is mainly found in endosomal (Ara7- and FM4-64-positive) compartments, but also at the plasma membrane, where it mediates binding and internalization of its natural ligand transferrin (Tfn). Cell surface expression of hTfR increases upon treatment with tyrphostin A23, which inhibits the interaction between the YTRF endocytosis signa…

Licofelone, a novel 5-LOX/COX-inhibitor, attenuates leukocyte rolling and adhesion on endothelium under flow

2005

The main mechanism of action of non-steroidal anti-inflammatory drugs (NSAIDs) is the inhibition of cycloxygenases COX-1 and COX-2. During recent years, combined 5-LOX/COX-inhibition, interfering with the biosynthesis of both prostaglandins and leukotrienes (LTs), has emerged as a possibility to avoid side effects related to COX-inhibition. The aim of the present study was to investigate if there is a contribution of mechanisms other than the reduction of inflammatory prostaglandins and leukotrienes to the anti-inflammatory effect of the LOX/COX inhibitor licofelone. In a flow chamber assay, licofelone (10-30 microM) dose-dependently decreased both the rolling and adhesion of leukocytes on …
