Phytochemical Profile and Antioxidant, Antiproliferative, and Antimicrobial Properties of Rubus idaeus Seed Powder
2022
In the context of the contemporary research on sustainable development and circular economy, the quest for effective strategies aimed at revaluation of waste and by-products generated in industrial and agricultural production becomes important. In this work, an ethanolic extract from red raspberry (Rubus idaeus) seed waste (WRSP) was evaluated for its phytochemical composition and functional properties in term of antioxidative, antiproliferative, and antimicrobial activities. Chemical composition of the extract was determined by both HPLC-ESI-MS/MS and spectrophotometric methods. Phytochemical analysis revealed that flavan-3-ols and flavonols were the major phenolic compounds contained in W…
Constituents of leaves and flowers essential oils of Helichrysum pallasii (Spreng.) Ledeb. growing wild in Lebanon.
2009
The chemical compositions of the essential oils obtained from leaves and flowers of Helichrysum pallasii were analyzed by gas chromatography and gas chromatography-mass spectrometry. Among the 102 identified constituents, hexadecanoic acid (16.2%), (Z,Z)-9,12-octadecadienoic acid (6.8%), tetradecanoic acid (2.6%), and (Z)-caryophyllene (4.2%) were the main constituent of the oil from leaves, while in the oil from flowers hexadecanoic acid (14.7%), (Z,Z)-9,12-octadecadienoic acid (14.2%), (Z)-caryophyllene (3.6%), and delta-cadinene (3.1%) predominated. The oils were both characterized by sesquiterpenes (33.4% for leaves and 33.7% for flowers, respectively) and fatty acids and esters (30.3% …
The inhibitory effect of a novel neem paste against cariogenic bacteria
2021
Background Dental caries is a major oral health problem, which associates with cariogenic bacteria. Streptococcus mutans and Lactobacillus acidophilus are facultative anaerobic bacteria that are found in tooth decay. Accordingly, neem leaf extract was developed due to its great anti-microbial property against many bacteria. The aim of this study was to determine anti-cariogenic properties of neem leaf extract in a novel paste preparation. Material and Methods The neem extract was derived from maceration of dry neem leaves in ethanol for 48 h. The ethanolic extract was subjected to chemical identification using GC-MS. Neem pastes were prepared from ethanolic extract mixed with polyethylene g…
Computer-aided detection of cerebral microbleeds in susceptibility-weighted imaging.
2014
Susceptibility-weighted imaging (SWI) is recognized as the preferred MRI technique for visualizing cerebral vasculature and related pathologies such as cerebral microbleeds (CMBs). Manual identification of CMBs is time-consuming, has limited reliability and reproducibility, and is prone to misinterpretation. In this paper, a novel computer-aided microbleed detection technique based on machine learning is presented: First, spherical-like objects (potential CMB candidates) with their corresponding bounding boxes were detected using a novel multi-scale Laplacian of Gaussian technique. A set of robust 3-dimensional Radon- and Hessian-based shape descriptors within each bounding box were then ex…
The “λ-medial axis”
2005
Medial axis is known to be unstable for nonsmooth objects. For an open set O, we define the weak feature size, wfs, minimum distance between Oc and the critical points of the function distance to Oc. We introduce the "lambda-medial axis" Mλ of O, a subset of the medial axis of O which captures the homotopy type of O when λ < wfs. We show that, at least for some "regular" values of λ, Mλ remains stable under Hausdorff distance perturbations of Oc.
Carbon input threshold for soil carbon budget optimization in eroding vineyards
2016
Abstract Previous studies have documented that, relative to conventional tillage (CT), alternative soil management (reduced tillage, mulching, or cover crops) decreases soil erosion and increases soil organic matter (SOM) in vineyards. These previous studies, however, failed to consider the loss of soil organic carbon (SOC) with erosion that could occur with the adoption of agro-environmental measures (AEM) in a semiarid environment. Accordingly, the aims of this study were to determine whether changes in SOC content under AEM management are always positive and to develop a conceptual model for estimating the “SOC threshold”. The SOC threshold was defined as that level of SOC in an AEM-mana…
Darba samaksas aprēķināšanas kārtība un ar to saistīto nodokļu ieturēšanas nianses un analīze
2017
Diplomdarba mērķis ir, pamatojoties uz izstrādāto Nodokļu politikas stratēģiju 2011. – 2014. gadam un Nodokļu politikas stratēģiju 2015. – 2017. gadam, identificēt problēmas un izstrādāt priekšlikumus darbaspēka nodokļu sloga samazināšanai Latvijā. Diplomdarbā izpētīti darba samaksas veidi, analizēti ieturējumus no darba algas, izvērtētas darbaspēka nodokļu izmaiņas, salīdzināti darbaspēka nodokļi Baltijas valstīs, izvērtēta algas nodokļu izmaiņu ietekme uz ieņēmumiem, novērtēts darbaspēka nodokļu slogs. Pētījuma rezultātā atklātas problēmas un izstrādāti priekšlikumi, lai mazinātu augsto nodokļu slogu iedzīvotājiem ar zemiem ienākumiem un risinātu darbaspēka nodokļu nākotnes attīstību. Dip…
Iedzīvotāju ienākuma nodoklis Latvijā un ES
2020
Bakalaura darba tēma ir “Iedzīvotāju ienākuma nodoklis Latvijā un ES”. Iedzīvotāju ienākuma nodoklis, pēc Valsts Ieņēmumu Dienesta datiem, ir viens no ienesīgākajiem nodokļiem. IIN maksātāji ir visi iedzīvotāji, kuriem ir oficiāli ienākumi, tāpēc ir svarīgi visiem nodokļa maksātājiem sekot līdzi šim būtiskam izdevumu postenim. Balstoties uz izvirzīto hipotēzi, ka Ienākuma nodokļa slogs Latvijā ir augsts, salīdzinot ar Eiropas Savienības valstīm, tika izvirzīti sekojoši uzdevumi: 1. Izanalizēt Iedzīvotāju ienākuma nodokļa saistošos noteikumus, likumu, Valsts ieņēmumu dienesta sniegtos materiālus. 2. Veikt IIN aprēķinus nodokļu maksātājiem. 3. Izanalizēt IIN sistēmu, nodokļu apmērus un piemēr…
A Synthetic View of Different Concepts of Creditor Protection - Or a High-Level Framework for Corporate Creditor Protection
2006
Protection of corporate creditors has become an important topic within the European Union. At EU level, discussion has been sparked by widespread dissatisfaction with some very rigid and cumbersome provisions, and even with the whole concept of the Second Company Law Directive. At EU Member State level, three landmark decisions by the European Court of Justice — Centros, Uberseering, and Inspire Art — opened the way for an all-out competition between the different company forms provided for by national company laws. At both levels, albeit for different reasons, British company law — and in particular the absence of any legal capital in the private limited company — acts as the main driving …
Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.
2016
Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…
