Antimikrobo līdzekļu menedžments stacionārā pnemonijas pacientiem
2019
Bakalaura darbs „Antimikrobo līdzekļu menedžments stacionārā pneimonijas pacientiem”. Tēmas aktualitāti nosaka elpošanas sistēmas saslimšanas gadījumu skaita palielināšanās, ar to saistīto antimikrobo līdzekļu lietošanas biežuma pieaugums un rezistento mikroorganismu attīstība. Darba mērķis ir noskaidrot antimikrobo līdzekļu menedžmenta realizāciju stacionārā pneimonijas pacientiem. Pētniecības metode – kvalitatīvā, instruments - intervija. Pētniecības jautājums: “Kā tiek realizēts antimikrobo līdzekļu terapijas menedžments pneimonijas pacientiem Intensīvās terapijas klīnikā?” Pētījuma rezultāti apliecina, ka Intensīvās terapijas klīnikā praktizējošās māsas izprot un īsteno antimikrobo līdz…
Effect of Three Different Aloe vera Gel-Based Edible Coatings on the Quality of Fresh-Cut “Hayward” Kiwifruits
2020
In recent years, the market for minimally processed fruit has increased. Fresh-cut fruits are characterized by a short shelf life due to the processing phases that accelerate the ripening courses. The aim of this work is to analyze the effect on the quality of fresh-cut Hayward kiwis of three different edible coatings based on (1) Aloe vera gel, (2) Aloe vera gel + hydroxypropyl methylcellulose and (3) Aloe vera gel + lemon essential oil. Fruit firmness, weight loss, color, soluble solids content, titratable acidity, microbial load and sensory analysis were evaluated as fresh after 2, 4, 7 and 10 days. Aloe vera gel and Aloe vera gel + lemon essential oil maintained the best values, as they…
Staphylococcal Biofilms: Challenges in the discovery of Novel Anti-Infective Agents
2011
Novel chemical countermeasures against staphylococcal biofilms
2010
Some natural and synthetic related pyrrolomycins, a family of halogenated pyrrole antibiotics, showed anti-biofilm properties in vitro at low concentration (0.045μg/mL) against preformed staphylococcal biofilms. Moreover, considering the human cell toxicity, the selectivity indexes (ratio of cytotoxicity to antibiofilm activity) of some of them were very interesting. The present study aims to investigate if the pyrrolomycins could also prevent staphylococcal biofilm formation. The evaluation of S.aureus ATCC 25923 biofilm formation inhibition was conducted by safranin staining method. At tested concentrations of 0.18, 0.09, 0.045 μg/mL (concentrations much lower than MIC value determined on…

Pectin: A Long-Neglected Broad-Spectrum Antibacterial.
2020
First reported in the late 1930s and first partly explained in 1970, the antibacterial activity of pectin remained almost ignored until the late 1990s. The concomitant emergence of research on natural antibacterials and on new usages of pectin polysaccharides, including those in medicine widely researched in Russia, has led to a renaissance of research in the physiological properties of this uniquely versatile polysaccharide ubiquitous in plants and fruits. Collecting scattered information, this study provides an updated overview on the subtle factors affecting the behaviour of pectin as antimicrobial. Less degraded pectin extracted via acid-free routes, we argue in the conclusions, will so…
Antimicrobial additives for poly(lactic acid) materials and their applications: current state and perspectives
2018
Poly(lactic acid)-based antimicrobial materials received considerable attention as promising systems to control microbial growth. The remarkable physicochemical properties of PLA such as renewability, biodegradability, and US Food and Drug Administration (FDA) approval for clinical use open up interesting perspectives for application in food packaging and biomedical materials. Nowadays, there is an increasing consumer demands for fresh, high-quality, and natural foods packaged with environmentally friendly materials that prolong the shelf life. The incorporation of antimicrobial agents into PLA-based polymers is likely to lead to the next generation of packaging materials. The development o…
