Comparison of Antibiotic Resistance Profile and Biofilm Production of
2019
Background: The diffusion of antimicrobial resistance is a significant concern for public health worldwide. Staphylococcus aureus represents a paradigm microorganism for antibiotic resistance in that resistant strains appear within a decade after the introduction of new antibiotics. Methods: Fourteen S. aureus isolates from human specimens and twenty-one from samples of animal origin, were compared for their antimicrobial resistance and biofilm capability. In addition, they were characterized at the molecular level to detect the antimicrobial resistance mecA gene and genes related with enterotoxin, toxin, and biofilm production. Results: Both phenotypic and molecular analysis showed main di…
Canopy Architecture Appraisal by Fractal Dimension of 'Flordastar' Peach Trees Grafted onto Different Rootstocks
2007
The objective of this research was to evaluate the modification of canopy architecture of ''Flordastar'' peach (Prunus persica L. Batsch) grafted onto rootstocks with different vigour, by the use of fractal dimension (D). The hypothesis was that different vigour rootstocks are able to modify the complexity of the branching pattern and that this effect can be assessed by a geometric parameter such as the fractal dimension (D) of the 2D projection of tree branching structure. The observations were carried out in a four-year-old experimental orchard of cv. ''Flordastar'' peach trees grafted onto Ishtara, Barrier, GF677 and MrS 2/5 rootstocks. On digital pictures of leafless, dormant peach tree…
Staphylococcus aureus rezistence pret antimikrobajām vielām
2017
Darba aktualitāte: Staphylococcus aureus ir viens no būtiskākajiem plaša spektra infekciju izraisītājiem visā pasaulē. Tā mikrobioloģiskās īpašības un izraisītās slimības mūsdienās ir labi izpētītas, taču nav pieejama ne vakcīna, ne citi pietiekami efektīvi drošības pasākumi. Mikroorganismu multirezistentie celmi veido nozīmīgu ar veselības aprūpi saistīto infekciju daļu, ar ko ikdienā nākas sastapties stacionāros esošajiem pacientiem un personālam. S.aureus meticilīnrezistentais (MRSA) celms, pateicoties savām īpašībām, ir rezistents pret visiem beta laktāmu grupas antimikrobajiem līdzekļiem un ir plaši izplatīts kā Eiropā, tā citur pasaulē. Tas sadārdzina veselības aprūpes izmaksas, pagar…
No sejas ādas mikrobiotas izdalīto Staphylococcus aureus jutība pret antibakteriālajiem līdzekļiem
2021
Darba aktualitāte: Pēdēja laikā Staphylococcus aureus rezistence pret zālēm nemitīgi palielinājās. Pret antibiotikām rezistentas baktērijas tiek uzskatītas par vienu no mūsdienu nopietnākajiem draudiem cilvēku veselībai. Darba mērķis: Noteikt baktēriju sejas ādas kolonizāciju veseliem cilvēkiem un noskaidrot izolēto S.aureus celmu jutību pret antibakteriāliem līdzekļiem. Pielietotas metodes: Tika pielietoti BBL™ disku difūzijas testi un Crystal™ ID metode, E-testi. Datu analīzei tika izmantota Microsoft Excel 2019 datorprogramma. Rezultāti: S.aureus izolātiem tika noteikta 100% jutība pret cefoksitīnu (MSSA), vankomicīnu un rezistence pret klindamicīnu – 6,7%, eritromicīnu – 6,7%, ciproflok…
MRSA ST22-IVa (EMRSA-15 clone) in Palermo, Italy
2010
Summary: Epidemic spread of methicillin-resistant Staphylococcus aureus (MRSA) strains carrying the Staphylococcal Chromosomal Cassettes (SCC) mec type IV is being increasingly reported in many geographical areas. A survey to determine the prevalence and characteristics of MRSA SCCmec IV isolates identified in four general hospitals in Palermo, Italy, was carried out. During the period February–June 2009, SCCmec type IVa has been found in 12 out of 94 isolates. Nine isolates from all hospitals and all strains from a NICU outbreak occurring in the same period were attributed with the ST22-IVa (EMRSA-15) clone. In our setting, due to the changing MRSA epidemiology, detection of SCCmec IV coul…
PLASMA MEMBRANE REDOX SYSTEM IN THE ERYTHROCYTES OF ROWERS: PILOT STUDY
2015
Background: The oxidative stress results from a change in the physiological balance between oxidant and antioxidant species. The purpose of this study is twofold: first, to investigate the effects of long-term training in sports with high energy requirements on the redox balance which exists between the plasma vs. the erythrocytes; second, to study the activity of the PMRS (Plasma Membrane Redox System), which is a compensatory mechanism of cellular redox homeostasis, in the rowers’ erythrocytes in order to determine the rowers’ counteraction to oxidative stress. Methods: Venous blood samples was collected from rowers and control group; then FRAP (Ferric Reducing Activity Power) method has …
Glioma Grading: The Role of Combined Perfusion MR Imaging and Single-Voxel MR Spectroscopy Compared to Conventional MR Imaging
2011
Abstract Body: Purpose To assess the contribution of combined perfusion MR imaging (MRI) and single-voxel MR spectroscopy (MRS) in grading primary gliomas compared with conventional MRI. Materials & Methods Thirty-two patients with primary cerebral glioma underwent conventional MRI, dynamic contrast-enhanced T2*-weighted perfusion MRI and single-voxel proton MRS. Gliomas were graded as low or high based on conventional MRI. The rCBV measurements were obtained from regions of maximum perfusion normalized between tumor and healthy tissue. Metabolite ratios ( [Cho]/[Cr], [Cho]/[NAA], [NAA]/[Cr]) were measured with TE: 34 ms. Tumor grade determined with the three methods then was compared with …

Adenosine A2A and A2B Receptors Differentially Modulate Keratinocyte Proliferation: Possible Deregulation in Psoriatic Epidermis
2017
Adenosine is a potent regulator of inflammation and immunity, but the role of adenosine receptors in keratinocytes remains controversial. We determined that in addition to A2B receptors, human epidermal keratinocytes also express A2A receptors, although to a lower extent. Through the use of selective adenosine receptor agonists and antagonists, we showed that physiological concentrations of adenosine activate A2B receptors in normal human keratinocytes, inducing cell cycle arrest through the increase of intracellular calcium but not through cAMP signaling. In contrast, the selective activation of A2A receptors by CGS-21680 induces keratinocyte proliferation via p38–mitogen-activated protein…
Evidence for Human Adaptation and Foodborne Transmission of Livestock-Associated Methicillin-Resistant Staphylococcus aureus
2016
We investigated the evolution and epidemiology of a novel livestock-associated methicillin-resistant Staphylococcus aureus strain, which colonizes and infects urban-dwelling Danes even without a Danish animal reservoir. Genetic evidence suggests both poultry and human adaptation, with poultry meat implicated as a probable source.
