Wharton’s Jelly Mesenchymal Stem Cells as Candidates for Beta Cells Regeneration: Extending the Differentiative and Immunomodulatory Benefits of Adul…
2010
Mesenchymal stem cells (MSC) are uniquely capable of crossing germinative layers borders (i.e. are able to differentiate towards ectoderm-, mesoderm- and endoderm-derived cytotypes) and are viewed as promising cells for regenerative medicine approaches in several diseases. Type I diabetes therapy should potentially benefit from such differentiated cells: the search for alternatives to organ/islet transplantation strategies via stem cells differentiation is an ongoing task, significant goals having been achieved in most experimental settings (e.g. insulin production and euglycaemia restoration), though caution is still needed to ensure safe and durable effects in vivo. MSC are obtainable in …
Sogni erotici e seme femminile nella antica medicina greca
2009
This paper analyses passages of the Hippocratic Corpus, of Aristotle and Galen about oneirogmòs, spermatic emission during sleep, referring specifically to women. Into the Hippocratic texts there is only one gynaecological case among many cases about males: for them this nocturnal emission is symptom of dangerous illness and De genitura gives a causal explanation of such phaenomenon. Instead, in Aristotle and Galen erotic dream is evidence for or against emission of female seed and female contribution to generation. As the argument of Historia animalium book X shows clear theoretical differences from that of De generatione animalium, the topic of erotic dream also concerns issues of authent…

A stress-responsive miRNA regulates BMP signaling to maintain tissue homeostasis
2021
Adult organisms must sense and adapt to environmental fluctuations. In high-turnover tissues such as the intestine, these adaptive responses require rapid changes in gene expression that, in turn, likely involve posttranscriptional gene control. However, intestinal-tissue-specific microRNA (miRNA)-mediated regulatory pathways remain unexplored. Here, we report the role of an intestinal-specific miRNA, miR-958, that non-cell autonomously regulates stem cell numbers during tissue homeostasis and regeneration in the Drosophila adult midgut. We identify its downstream target cabut, the Drosophila ortholog of mammalian KLF10/11 transcription factors, which mediates this miR-958 function by promo…
The Rewilding Approach in Urban Design. The Case Study of Budolfi Plads in the Historic Centre of Aalborg (DK)
2023
Dwelling on Earth responsibly means guaranteeing global environmental well-being, within which the habitable environment for human beings must find a new homeostasis. At the turn of the second and third millennium, tackling environmental degradation and halting the continued loss of biodiversity became a global policy goal. In this context, new approaches to biodiversity conservation and ecosystem restoration are emerging, such as rewilding, an approach that aims to strengthen the adaptive capacity of ecosystems by restoring natural processes and minimizing human management. The article analyses urban rewilding as a design approach aimed at restoring natural processes and reintroducing natu…
Green Spectroscopy: A Scientometric Picture
2009
ABSTRACT The state of the art of green spectroscopy, as a sustainable and friendly alternative to the classical spectrometric methods of analysis, has been established from the evaluation of the scientific literature published about this topic in the frame of the so-called Green Chemistry paradigm. Special attention has been paid to the fact that keywords like Green Analytical Chemistry, environmentally friendly, or clean analytical method or sustainable analytical chemistry are far from being commonly used in analytical studies. In spite of this fact there are numerous studies that provide direct analytical methodologies, or a reduction of reagents consumption or waste generation, the recy…
Online mass flow prediction in CFB boilers with explicit detection of sudden concept drift
2010
Fuel feeding and inhomogeneity of fuel typically cause fluctuations in the circulating fluidized bed (CFB) process. If control systems fail to compensate the fluctuations, the whole plant will suffer from dynamics that is reinforced by the closed-loop controls. This phenomenon causes reducing efficiency and the lifetime of process components. In this paper we address the problem of online mass flow prediction, which is a part of control. Particularly, we consider the problem of learning an accurate predictor with explicit detection of abrupt concept drift and noise handling mechanisms. We emphasize the importance of having domain knowledge concerning the considered case and constructing the…
Piantare alberi. Storie e modelli di crescita nel "Cato maior de senectute" di Cicerone
2019
Is the idea of “growing” and “development” useful to explain a work about senectus? The aim of this paper is to verify if Cicero’s Cato maior may offer a literary portrayal of “growth” in a double way: the biological one, with the human being intended as a mere individual, and the cultural one, relevant to human generations. The use of words and expressions from the rural context seems to enable Cicero to place the elderly in a justified relationship with the others ages of life, as he was rethinking the conflict of generations, because this opposition always talks about the ways every society conceives and describes itself.
NEW GUIDED BONE REGENERATION PROCEDURE USING LEUKOCYTE AND PLATELET RICH FIBRIN (L PRF) IN ORAL SURGERY
2021
Non-transfusional hemocomponents are autogenous products used in several surgical fields obtained by the centrifugation of a blood sample from a patient and able to promote hard and soft tissue regeneration, local haemostasis, and the acceleration of wound healing. The aim of this PhD thesis was the validation of an innovative protocol for the Guided Bone Regeneration (GBR) technique using second-generation autologous platelet concentrates, Leukocytes and Platelet-rich Fibrin (L-PRF), in post-extraction sockets of patients in need of dental avulsions and successive implant prosthetic rehabilitation, evaluating its ability to prevent alveolar bone resorption and promote bone regeneration. Th…
Cystic degeneration of uterine leiomyoma during ulipristal acetate treatment
2016
Degenerative cyst formation is a rare phenomenon in-between uterine leiomyomas, however, both patients and physicians have to be aware of this possibility when using ullipristal acetate as this event may guide to the inaccurate diagnosis of an adnexal malignant pathology.
