International Society for Extracellular Vesicles: first annual meeting, April 17-21, 2012: ISEV-2012
2012
Extracellular micro- and nano-scale membrane vesicles produced by different cells are recognized as an essential entity of physiological fluids in a variety of organisms and function as mediators of intercellular communication employed for the regulation of multiple systemic and local processes. In the last decade, an exponential amount of experimental work was dedicated to exploring the biogenesis and secretion mechanisms, physiological and pathological functions and potential applications of the extracellular vesicles (EVs). Noteworthy is the large heterogeneity of in vitro and in vivo models applied, technical approaches developed in these studies and the diversity of designations assign…
The determination of trace element concentrations in fly ash samples using ultrasound-assisted digestion followed with inductively coupled plasma opt…
2009
A method of ultrasound-assisted digestion followed by inductively coupled plasma optical emission spectrometry (ICP-OES) used for the determination of trace element (chromium, copper, lead, nickel, vanadium and zinc) concentrations in fly ash samples was developed. All the measurements were performed in robust plasma conditions. Ultrasound-assisted digestion procedures using digestion solutions of aqua regia and hydrofluoric acid (HF) resulted in recovery rates of over 80% for all the analyte elements. Ultrasound-assisted two-step digestion with digestion solutions of 6 mL of HNO₃(Step 1) and 3 mL of HNO₃+ 3 mL of HF (Step 2) resulted in recovery rates of over 92% for all the analyte elemen…
Current Acquaintance on Agronomic Biofortification to Modulate the Yield and Functional Value of Vegetable Crops: A Review
2023
Fresh vegetables and fruits have always been the mainstays of good nutrition as providers of fiber, beneficial phytochemicals (such as vitamins and phenolic compounds), and minerals. Today and in the future, biofortification is a promising strategy to increase the concentration of these compounds. Considering the importance of minerals in human health, the enrichment of fresh produce for consumption has been considered through specific agronomic approaches. This review discusses, in detail, the latest findings on vegetable agronomic biofortification, aimed at increasing the concentration of crucial minerals, such as iron (Fe), zinc (Zn), iodine (I), selenium (Se), molybdenum (Mo), and silic…
Oral contraceptives in the prevention of endometrioma recurrence: does the different progestins used make a difference?
2013
""The primary aim of the study was to analyze the endometrioma recurrence rate in patients who underwent laparoscopic excision followed by postoperative long-term regimen of oral contraceptives (OCs).. . MATERIALS AND METHODS: 168 patients who underwent a conservative laparoscopic surgery for endometrioma, during the period between September 2009 and August 2010 in three university hospitals were studied. A long-term OCs therapy was offered to all women following surgery. Patients were randomly divided into three groups according to different progestins used (desogestrel, gestodene, dienogest). Women who refused a postoperative hormonal therapy served as control. Follow-up visits and transv…

De monstroso partu
1596
1596. g. Rīgā, Nikolausa Mollīna tipogrāfijā nodrukāta humānista Daniela Hermaņa (Daniel Hermann) poēma “De monstroso partu” (Par monstra dzimšanu). Autors precīzi attēlo Livonijā dzimušu bērnu ar iedzimtiem defektiem. Dzejnieks velk paralēles starp bērna deformētajiem orgāniem un valsts politisko un reliģisko stāvokli. Šis monstrs ir zīme jeb simbols Livonijai. Sabiedrībā šie monstri tiek uztverti kā laba vai ļauna zīme, kas pareģo nākotni vai brīdina. 16. gs. tie iegūst simbolisku nozīmi reliģiskās konfrontācijas. Aktuāli jautājumi – vai monstriem ir dvēsele, no kurienes tie cēlušies, kāpēc šādi cilvēki dzimst – izskan poēmas rindās un tiek interpretēti attiecīgi laikmetam. Reizē ar monst…
Theatrum niezwykłości w "Kronice wszytkiego świata" Marcina Bielskiego
2016
Praca dotyczy fenomenu niezwykłości w dawnych wiekach. Przedmiotem analizy stała się XVl-wieczna Kronika wszystkiego świata Marcina Bielskiego, która obfituje w bogaty materiał najrozmaitszych dziwów i cudowności. Struktura Kroniki Bielskiego współtworzy rodzaj theatrum, tj. kręgu wiedzy (gr. enkyklios paideia), gdzie realnie istniejące uporządkowane w przestrzeni rzeczy zostały nic tylko zinterpretowane i sklasyfikowane, ale też podporządkowane kategoriom zarówno systemu moralnego, jak i teologicznego. Wyłania się więc z encyklopedycznego dzieła Bielskiego świat pełen ładu, harmonii oraz sensu, taki, w którym swoje miejsce i znaczenie zyskuje każda nawet najbardziej nietypowa i dziwaczna r…
Active biomonitoring (moss-bags) of volcanic emissions on Mt. Etna
2011
Biomonitoring may be defined as the use of organisms and biomaterials (biomonitors) to obtain information on certain characteristics of a particular medium (atmosphere, hydrosphere etc.). In particular, mosses accumulate large amounts of trace metals, making them good bioaccumulators to estimate atmospheric pollution. The moss-bags technique, introduced in the early 1970’, has become very popular. Such active biomonitoring technique is particularly useful in highly polluted areas and has been extensively used in industrial and/or urban areas to examine deposition patterns and to recognize point sources of pollution. The main objective of this study, which represents the first application of…
A new species within the Centaurea busambarensis complex (Asteraceae, Cardueae) from Sicily
2022
The Centaurea busambarensis group is made up by eight species endemic to Sicily. We statistically evaluated a population found on the Nebrodi Mountain (NE Sicily) to verify if the observed morphological differences with the already known taxa justified the description of a new one. It resulted in being sufficiently distinct to deserve recognition at the species level. Centaurea valdemonensis, a new species endemic to Sicily is described and illustrated here. It is confined to the Nebrodi Mountains (NE Sicily). The distinction of this taxon from the others belonging to the C. busambarensis complex has been supported with the aid of statistical analyses on morphological characters. The differ…
Freedom, Civility and Activeness. On the government of leisure self-formation of Finnish multicultural youth
2012
This article explores the leisure time and civic activities of ‘multicultural youth’ in Finland. The theoretic-conceptual framework is the Foucauldian governmentality approach and Foucault's four step model of the ethical self-formation of the moral subject. This toolkit exposes how the subjectivation of the multicultural youth takes place in their leisure time activities and civic action, and connects and disconnects with the desires and expectations of administration and youth workers. The leisure time subjectivation of the youth implements on the interface of their own ‘self-driven’ activities and interests and more or less programmatic governance of official youth work with its integrat…
