Vascular Risk Factors in Mild Cognitive Impairment Subtypes

2007

<i>Background and Aim:</i> To investigate the role of vascular risk factors in different subtypes of mild cognitive impairment (MCI) in a multicentric, clinic-based, cross-sectional study. <i>Methods:</i> Two-hundred and seven subjects with MCI were included in the study: 33 with single non-memory MCI (snmMCI), 42 with multiple-domain amnestic MCI (mdMCI-a) and 132 with amnestic MCI (aMCI). Several clinical vascular risk factors and magnetic resonance imaging (MRI) brain lesions were evaluated. <i>Results:</i> snmMCI showed a higher frequency of ischaemic heart disease and of transient ischaemic attack (TIA)/stroke, a higher Hachinski ischaemic score and …

Izmantoto disciplinēšanas tehniku saistība ar vecāku kompetences izjūtu pirmsskolas vecuma bērnu vecākiem

2021

Bakalaura darba pētījuma mērķis bija noteikt saistības starp vecāku izmantotajām disciplinēšanas tehnikām un vecāku kompetences izjūtu pirmsskolas vecuma bērnu vecākiem. Pētījumā piedalījās 50 vecāki (44 mātes un 6 tēvi), kuriem vismaz viens bērns ir vecumā no 3 līdz 5 gadiem (25 meitas un 25 dēli: 23 bija 3 gadīgi, 16 bija 4 gadīgi un 11 bija 5 gadīgi). Tika veikts korelatīvs pētījums, izmantojot instrumentus: “Vecāku kompetences izjūtas skala” (Parenting sense of competence scale, Johnston & Mash, 1989). Latviešu valodā skalu adaptējušas I. Skreitule – Pikše, S. Sebre (Skreitule-Pikše, I., Sebre, S., 2008) un “Aptauja par disciplinēšanas tehnikām”, kas ir izveidota šī pētījuma vajadzībām.…

Author Correction: Evaluation of three methods for biomass estimation in small invertebrates, using three large disparate parasite species as model o…

2018

Invertebrate biomass is considered one of the main factors driving processes in ecosystems. It can be measured directly, primarily by weighing individuals, but more often indirect estimators are used. We developed two indirect and non-destructive approaches to estimate biomass of small invertebrates in a simple manner. The first one was based on clay modelling and the second one was based on image analysis implemented with open-source software. Furthermore, we tested the accuracy of the widely used geometric approximation method (third method). We applied these three different methods to three morphologically disparate model species, an acanthocephalan worm, a crustacean and a flatworm. To …

Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.

2011

Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…

Inferring Phytoplankton, Terrestrial Plant and Bacteria Bulk δ¹³C Values from Compound Specific Analyses of Lipids and Fatty Acids.

2015

Stable isotope mixing models in aquatic ecology require δ13C values for food web end members such as phytoplankton and bacteria, however it is rarely possible to measure these directly. Hence there is a critical need for improved methods for estimating the δ13C ratios of phytoplankton, bacteria and terrestrial detritus from within mixed seston. We determined the δ13C values of lipids, phospholipids and biomarker fatty acids and used these to calculate isotopic differences compared to the whole-cell δ13C values for eight phytoplankton classes, five bacterial taxa, and three types of terrestrial organic matter (two trees and one grass). The lipid content was higher amongst the phytoplankton (…

Environmental remediation using nanomaterial as adsorbents for emerging micropollutants

2023

Water shortage and scarcity are issues of global concern. Water pollution caused by organic micropollutants further aggravates the problem, by rendering an already scarce resource unfit for human consumption. The existing conventional wastewater treatment methods and infrastructure were not designed to eliminate micropollutants. Therefore, their inefficiencies call for modern methods for removing emerging micropollutant residues such as Active Pharmaceutical Ingredients (APIs), Endocrine Disrupting Compounds (EDCs), personal care products and pesticides. The use of nanomaterials, for the abatement of micropollutants in water is gaining traction in recent years, due to the abundance of susta…

L’image des légumes

2017

Au sein du vaste champ de recherche qu’est l’alimentation, les légumes et les représentations qu'en ont les mangeurs ont été délaissés malgré la place importante qu'ils occupent dans les discours officiels depuis la mise en place en 2001 du PNNS. Dans un contexte de stagnation de leur consommation, il semble judicieux de tenter de comprendre quels en sont les freins. Notre hypothèse veut que les discours médiatiques sur le sujet, dans la lignée du discours des autorités publiques, présentent les légumes avant tout comme un aliment fonctionnel, dans un pays où le goût et le plaisir restent pourtant des piliers de la culture alimentaire. Pour mettre à l’épreuve ce postulat, notamment à traver…
