Laryngeal involvement in relapsing polychondritis: Case report and review of literature

2018

Relapsing polychondritis is a rare multisystem autoimmune disease of unknown origin characterised by recurrent episodes of inflammation and progressive destruction of the cartilaginous structures and connective tissue of the whole body. The diagnosis of relapsing polychondritis is difficult. We present a review of the literature and describe a case of 49-year old woman. Her symptoms began in June 2004 with sore throat, dysphonia, pain in the thoracic wall and some joints, a slightly raised temperature and cough. The objective picture was immediately apparent after carrying out a high definition neck-thorax computed tomography and a laryngoscopy with fiber optics, which showed considerable l…

Importance of endophytic strains Pantoea agglomerans in the biological control of Rhizoctonia solani

2018

Antagonistic activity of microorganisms against phytopathogens is mainly the results of plants’ health improvement due to the inhibition of pathogens growth and the induction of plants resistance against diseases. The aim of the research was to determine antagonistic properties of Pantoea agglomerans against Rhizoctonia solani. The properties of two strains P. agglomerans BC17 and BC45 were assessed according to the following criteria: mycelial growth of R. solani in the presence of bacterial metabolites, an impact of P. agglomerans on the growth of sugar beet in the pots containing soil with and addition of R. solani and without it, the ability to produce indole-3-acetic acid (IAA). It has…

Diversity and composition of the microbiome associated with eggs of the Southern green stinkbug, Nezara viridula (Hemiptera: Pentatomidae).

2022

Although microbial communities of insects from larval to adult stage have been increasingly investigated in recent years, little is still known about the diversity and composition of egg-associated microbiomes. In this study, we used high-throughput amplicon sequencing and quantitative PCR to get a better understanding of the microbiome of insect eggs and how they are established using the Southern green stinkbug Nezara viridula (L.) (Hemiptera: Pentatomidae) as a study object. First, to determine the bacterial community composition, egg masses from two natural populations in Belgium and Italy were examined. Subsequently, microbial community establishment was assessed by studying stinkbug e…

Host glycoprotein Gp96 and scavenger receptor SREC interact with PorB of disseminating Neisseria gonorrhoeae in an epithelial invasion pathway.

2007

Neisseria gonorrhoeae expresses numerous surface proteins that mediate bacterial adherence and invasion during infection. Gonococci expressing serotype A of the major outer membrane porin PorB (PorB(IA)) are frequently isolated from patients with severe disseminating infections. PorB(IA) triggers efficient adherence and invasion under low phosphate conditions mimicking systemic bloodstream infections. Here, we identify the human heat shock glycoprotein Gp96 and the scavenger receptor SREC as PorB(IA)-specific receptors. Gonococci expressing PorB(IA), but not those expressing PorB serotype B instead, bind to purified native or recombinant Gp96. Depletion of Gp96 from host cells prevented adh…

A survey of the weedy communities of Sicily

2007

As Sicily has been a central crossroads of human activity for thousands of years, it offers a major perspective on the Mediterranean weedy plant communities. This syntaxonomical survey of the Sicilian weedy vegetation groups together for the first time 30 plant associations, that have been described from the main and neighboring island in the last three decades. The surveyed vegetation is ascribed to the classes Papaveretea rhoeadis and Stellarietea mediae, whose floristic autonomy is here discussed, and to the orders Aperetalia spicae-venti and Papaveretalia rhoeadis for the former, Polygono-Chenopodietalia polispermi, Solano-Polygonetalia convolvuli, Thero-Brometalia and Urtico-Scrophular…

Position paper on the management of patients with obstructive sleep apnea and hypertension: joint recommendations by the European Society of Hyperten…

2012

This article is aimed at addressing the current state of the art in epidemiology, pathophysiology, diagnostic procedures and treatment options for appropriate management of obstructive sleep apnea (OSA) in cardiovascular (particularly hypertensive) patients, as well as for the management of cardiovascular diseases (particularly arterial hypertension) in OSA patients. The present document is the result of the work done by a panel of experts participating in the European Union COST (COoperation in Scientific and Technological research) ACTION B26 on OSA, with the endorsement of the European Respiratory Society (ERS) and the European Society of Hypertension (ESH). These recommendations are par…

HPLC-DAD-ESI-MS2analytical profile of extracts obtained from purple sweet potato after green ultrasound-assisted extraction

2016

International audience; Ultrasound pre-treatment (UAE) was applied to assist the extraction of valuable compounds (polyphenols (especially anthocyanins), and proteins) from purple sweet potato (PSP). Under optimum conditions (ultrasound time (40 min); supplementary hot extraction (80 °C) up to 120 min; pH: 2.5; ethanol concentration: 58%), the highest concentrations of polyphenols (3.877 mg/g), anthocyanins (0.293 mg/g), and proteins (0.753 mg/g) were found, with minimal specific energy consumption (8406 J/mg).Moreover, anthocyanin and non-anthocyanin polyphenols in PSP extract from optimized extraction temperature were identified using HPLC-DAD-ESI-MS2. The major identified anthocyanins we…

Ultrasound-Assisted Extraction, Centrifugation and Ultrafiltration: Multistage Process for Polyphenol Recovery from Purple Sweet Potatoes

2016

This work provides an evaluation of an ultrasound-assisted, combined extraction, centrifugation and ultrafiltration process for the optimal recovery of polyphenols. A purple sweet potato (PSP) extract has been obtained using ultrasonic circulating extraction equipment at a power of 840 W, a frequency of 59 kHz and using water as solvent. Extract ultrafiltration, using polyethersulfone (PES), was carried out for the recovery of polyphenol, protein and anthocyanin. Pre-treatment, via the centrifugation of purple sweet potato extract at 2500 rpm over 6 min, led to better polyphenol recovery, with satisfactory protein removal (reused for future purposes), than PSP extract filtration without cen…

Retorisko jautājumu lietojums ēdienu gatavošanas emuāros

2022

Retoriskie jautājumi bija seno grieķu un romiešu intereses punkti. Tā kā retoriskajiem jautājumiem ir dažādas funkcijas, to izmantošana ir aktuāla arī mūsdienās. Šī pētījuma mērķis ir novērot retorisko jautājumu lietojumu astoņos dažādos ēdienu gatavošanas emuāros. Šajā pētījumā tika izmantotas divas pētījuma metodes – literatūras apskats un diskursa analīze. Tas ir gadījuma pētījums, jo attiecas uz atlasītu krājumu. Pētījuma rezultāti pierāda, ka nozīme ir cieši saistīta ar nodomu un kontekstu. Tāpat tika secināts, ka retoriskie jautājumi pieder pie sintakstisko izteiksmes līdzekļu grupas un, saskaņā ar dažādām klasifikācijām, pastāv astoņi retorisko jautājumu veidi – dianoeja, ratiocinati…
