New scenarios for neuronal structural plasticity in non-neurogenic brain parenchyma: the case of cortical layer II immature neurons
2011
The mammalian central nervous system, due to its interaction with the environment, must be endowed with plasticity. Conversely, the nervous tissue must be substantially static to ensure connectional invariability. Structural plasticity can be viewed as a compromise between these requirements. In adult mammals, brain structural plasticity is strongly reduced with respect to other animal groups in the phylogenetic tree. It persists under different forms, which mainly consist of remodeling of neuronal shape and connectivity, and, to a lesser extent, the production of new neurons. Adult neurogenesis is mainly restricted within two neurogenic niches, yet some gliogenic and neurogenic processes a…
"Zasiewający we łzach, w radości żąć będą" (Ps 126,5). Motywy radości w Psałterzu na przykładzie Psalmu 126
2016
Joy is one of the basic human feelings that express emotional, psychological, and spiritual state. Thus the biblical books and especially the Book of Psalms show various motifs of joy among numerous existential situations. Not only joy is the characteristic but its distinct reference to the relation with God as the One who is the source of joy even in the midst of worries and trials. It is exemplified by Psalm 126 which presents the motifs of joy included in the experience of sowing and harvesting. These motifs were raised accurately and meaningfully in the description of the situation of changing man’s lot from the state of sadness, caused by suffering, to joy and happiness of new life.
Protective Effect of Astaxanthin on Primary Retinal Cells of the Gerbil Psammomys Obesus Cultured in Diabetic Milieu
2017
Astaxanthin is a major marine carotenoid with powerful antioxidant and neuroprotective properties. The in vitro protective effect of astaxanthin in adult retinal cells of the type-2 diabetic model Psammomys obesus in hyperglycemic conditions was investigated. Primary retinal cells were cultured in normal (5 mM) or high concentrations of glucose (25 and 40 mM) for 5 days and treated with 1-20 μM astaxanthin for the last 48 h of culturing. Mitochondrial dehydrogenase activity and cell viability were assessed using MTT test and trypan blue exclusion dye. Retinal cells were characterized by immunohistochemistry. The results showed that mitochondrial function increased significantly (P<0.05) …
Seed germination reports for coastal sand dune species from Sicily
2019
This study investigated seed germination in nine psammophilous species occurring in Sicilian sand dunes, some of which, such as Muscari gussonei, Launaea resedifolia and Pancratium maritimum, are endemic and/or rare and very scattered in the area. Different germination protocols were tested for one or more populations and the best germination results per species are provided, reporting experimental conditions and specific comments on the germination behaviour.
Religiöse Haltung und politische Moral im Werk des exilierten deutsch-iranischen Autors SAID
2022
Ein ‚Weltbürger ohne ein eigenes Fenster’ - so bezeichnete sich selbst SAID, einer der wichtigsten zeitgenössischen iranischen Autoren, der seit langer Zeit in Deutschland lebte und publizierte. Obwohl Politik und Exil, zusammen mit Liebe und Religion, die zentralen Themenfelder seines literarischen Schaffens waren, verstand er sich nicht als politischer Autor. Vielmehr sah er sich als Augenmenschen, der die Realität aufmerksam beobachtete und mit seinen Werken das Gewissen seiner Leser in Bezug auf die schon lange andauernde politische und religiöse Unterdrückung im Iran aufrütteln wollte. Da gerade die Religion seit einigen Jahren SAIDs Lieblingsthema war, fokussiert sich der Beitrag auf …
Arka Noego obrazem Kościoła w "Enarrationes in Psalmos" św. Augustyna
2016
St. Augustine is regarded as master of the an allegorical interpretation of the Holy Scriptures. It consists in drawing out from the biblical text the deepest meaning. Using such kind of interpretation, he tried in one of his greatest exegetical works – Enarrationes in Psalmos, to explain for his faithful the mystery of the Church by means of a number of motives from the parables, biblical topographic and cosmic subjects, as well as from many biblical events and personages, interpreted in an allegorical spirit. So, in this article an effort has been made to how only some ideas of Augustine’s ecclesiological reflections that look as fruit of his allegorical interpretation of Noah’s Arc and t…
Symbolika księżyca w Enarrationes in psalmos św. Augustyna
2018
Niniejszy artykuł dowodzi, że Augustyn objaśniając w Enarrationes in Psalmos teksty Psalmów nie traktuje pojawiających się w nich odniesień do księżyca jedynie jako części opisów piękna stworzonego świata, ale stara się w nim dostrzec sens ukryty, którego ujawnienie służy wykładni różnych teologicznych zagadnień. Dla biskupa Hippony księżyc jest bowiem metaforą Boga Stwórcy, Chrystusa, Kościoła oraz człowieka. W odniesieniu do Boga Stwórcy księżyc ma przypominać chrześcijanom, iż Bóg stwarzając wszystko jako dobre i piękne sam jest Dobrem i Pięknem. Ponadto motyw księżyca ma wskazywać na samowystarczalność Boga, Jego wolność i niezależność. Księżyc jako metafora Chrystusa pozwala z kolei do…
Frailty and risk of complications in head and neck oncologic surgery. Systematic review and dose-response meta-analysis
2021
Background There is emerging evidence that frail individuals present a decreased physiological reserve, decreased ability to maintain homeostasis, and increased vulnerability to stressors. The concept of frailty has become increasingly recognized as a valuable measure in oncological surgical patients, including those with head and neck cancer. Preoperative screening for frailty may provide an individualized risk assessment that can be used by an interdisciplinary team for preoperative counseling and to improve outcomes. The aim of this meta-analysis was to evaluate the relationship between frailty and the risk of major postoperative complications in frail individuals submitted to head and n…
Polysarcosine-Based Lipids: From Lipopolypeptoid Micelles to Stealth-Like Lipids in Langmuir Blodgett Monolayers.
2016
Amphiphiles and, in particular, PEGylated lipids or alkyl ethers represent an important class of non-ionic surfactants and have become key ingredients for long-circulating (“stealth”) liposomes. While poly-(ethylene glycol) (PEG) can be considered the gold standard for stealth-like materials, it is known to be neither a bio-based nor biodegradable material. In contrast to PEG, polysarcosine (PSar) is based on the endogenous amino acid sarcosine (N-methylated glycine), but has also demonstrated stealth-like properties in vitro, as well as in vivo. In this respect, we report on the synthesis and characterization of polysarcosine based lipids with C14 and C18 hydrocarbon chains and their end g…
Light and Divine Wisdom: An Alternative Interpretation of the Iconography of the Fuller Brooch
2022
La spilla di Fuller viene considerata una rappresentazione, in ambito inglese, dei cinque sensi. Si ritiene che il personaggio centrale, che rappresenta la vista, presenti anche uno o più significati figurativi, legati a idee e concetti che erano correnti nel contesto culturale di re Alfredo. Questi significati figurativi dovevano presumibilmente essere enfatizzati e chiariti dai due oggetti che questa figura regge. Finora, tuttavia, questi oggetti non sono stati interpretati in modo soddisfacente, anche se la maggior parte degli studiosi ritiene che essi possano rappresentare delle piante o cornucopie. Il presente studio esplora l'ipotesi che questi oggetti siano in realtà delle torce, att…
