Evaluation of cell proliferation rate in non-dysplastic leukoplakias

2008

Objective: Analyze whether the most frequent cases of non-dysplastic leukoplakias, hyperkeratosis (H), acanthosis (A), and hyperkeratosis with acanthosis (HA) have similar cell proliferation rates and to compare them with epithelial dysplastic (ED) leukoplakias and normal oral epithelium (NOE).Study design: The sample comprised 10 cases of normal oral epithelium, 10 cases of hyperkeratosis, 10 cases of acanthosis, 10 cases of hyperkeratosis with acanthosis and 10 cases of epithelial dysplasia. The mean number of AgNORs per nucleus (mAgNOR) and the mean percentage of cells with 1, 2, 3 and 4 or more AgNORs per nucleus (pAgNOR) were recorded. Results: The results of mAgNOR showed differences …

Antiproliferative agents that interfere with the cell cycle at the G(1)-->S transition: further development and characterization of a small library o…

2008

In this continuation of our research on derivatives containing the stilbene privileged structure or that are derived from it, we report the results of further studies carried out on the previously initiated collection of compounds. We used a parallel synthetic approach to rapidly obtain small sets of compounds and started the annotation of the library in progress by calculating some physicochemical properties to be eventually correlated with biological activities. A pharmacophore for the antiproliferative activity was also built to summarize the features of the library. We evaluated the antiproliferative and pro-apoptotic activities of all compounds as well as the cell-cycle effects of some…

La Valle dei Templi in epoca medioevale. Caratterizzazione antropologica e paleopatologica delle sepolture antistanti in Tempio della Concordia

2021

Riassunto ― Il lavoro presenta i risultati delle analisi bio-archeologiche effettuate su resti scheletrici umani rinvenuti in quattordici sepolture di epoca medioevale rinvenute nel Parco Archeologico della Valle dei Templi di Agrigento (Sicilia). L’obiettivo è stato l’acquisizione delle informazioni necessarie per la ricostruzione del profilo biologico di ciascun individuo, al fine di determinarne il sesso, la stima dell’età biologica alla morte, la stima della statura e la valutazione delle patologie e degli indicatori di stress occupazionale mediante le correnti metodologie e tecniche diagnostiche di tipo antropologico. Sebbene il cattivo stato di conservazione di alcuni individui non ne…

Summary ― The work presents the results of the bio-archaeological analyzes carried out on human skeletal remains found in fourteen burials of Medieval chronology at the Archaeological Park of Valle dei Templi in Agrigentum (Sicily). The aim of the work was the acquisition of the information necessary for the reconstruction of the biological profile of each individual throught the determination of sex the estimate of the biological age at death the estimate of height and the evaluation of pathologies and markers of occupational stress through current anthropological diagnostic methodologies and techniques. Althought the poor state of conservation of some individuals has not allowed their whole anthropological characterization the investigations have highlighted the heterogeneity relating to the age groups and have allowed us to ascertain the presence of pathological alterations in subjects of mature age sometimes of unknown etiology such as DISH (Diffuse Idiopathic Hyperostosis). The sample size is not representative of the entire population but subsequent insights will provide a better understanding of the population dynamics of Medieval Agrigentum.Settore BIO/08 - Antropologia

An anthropological and paleopathological analysis of a peculiar skeleton from the Necropolis of Zancle (1st century BCE – 1st century CE): a case rep…

2022

The work presents the results of the anthropological and paleopathological analysis carried out on human skeletal remains of an individual (T-173) found in a burial from the necropolis “sector 96”, Messina, Sicily, dating back to the Roman Empire (1st century BCE – 1st century CE). The study aimed to acquire the information necessary for the reconstruction of the biological profi le. In fact, T173 is an adult male which is particularly interesting from a paleopathological point of view, showing skeletal anomalies from the cranial to the post-cranial skeleton probably caused by variations of genetic, neoplastic, articular and dental nature. Furthermore, the analyses have highlighted the poss…
