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…

Efficacy of stem cells in bone rehabilitation in patients with alveolar bone atrophy: a systematic review
2023
Background: Biomedical engineering proposes the use of stem cells as a bone rehabilitation treatment in patients with alveolar bone defects. Many authors suggest that this innovative technique could represent the future of bone regeneration in dentistry. The present study systematically reviewed the efficacy of stem cells in bone regeneration in patients with alveolar bone atrophy. Material and methods: The study was developed following the criteria of the PRISMA guideline (2020). The literature review was conducted in Pubmed, Medline Complete, and Scopus. The search algorithms used the following key words: stem cells, bone regeneration, and alveolar ridge augmentation. To assess the risk o…
Critical behavior of a tumor growth model: directed percolation with a mean-field flavor.
2012
We examine the critical behaviour of a lattice model of tumor growth where supplied nutrients are correlated with the distribution of tumor cells. Our results support the previous report (Ferreira et al., Phys. Rev. E 85, 010901 (2012)), which suggested that the critical behaviour of the model differs from the expected Directed Percolation (DP) universality class. Surprisingly, only some of the critical exponents (beta, alpha, nu_perp, and z) take non-DP values while some others (beta', nu_||, and spreading-dynamics exponents Theta, delta, z') remain very close to their DP counterparts. The obtained exponents satisfy the scaling relations beta=alpha*nu_||, beta'=delta*nu_||, and the general…
Extreme ameloblastoma of the mandible with hypoproteinemia. A case report and review of clinicopathological features
2011
Ameloblastoma is a tumor of odontogenic epithelium. It has an intermediate malignant potential, thus positioning it in a gray zone between benign and malignant neoplasms. Invasive ameloblastomas of excessive size are rarely confronted. Although these ameloblastomas are benign, they are life threatening. Many have eventuated in death due to airway obstruction, starvation from restriction of feeding, and complications of hypoproteinemia. These tumors cause significant expansion of skin and lips [tissue expanders]. Due to its metabolic demands, a tumor of enormous size will have numerous feeding vessels. Patients with extreme ameloblastomas are usually from rural areas of developing countries …
Routine Coronary Angiography is Still the Key Test for Patients Eligible for Lung Transplantation Also for Those With No Symptoms and With High Risk …
2022
Background. Coronary artery disease (CAD) has a considerable morbidity and mortality effect on the outcomes of a lung transplant. Currently, coronary angiography is performed as part of the pretransplant evaluation process. Unfortunately, there are no clear guidelines about performing cardiac angiography in lung transplant candidates. Background. The aim of our work is to find a correlation between cardiovascular risk and coronary arterial status to optimize the selection of patients for coronary angiography prior transplantation. Methods. We retrospectively analyzed 48 patients in whom coronary angiography and cardiac catheterization was performed during assessment for bilateral lung trans…
Pulmonary contusion: CT vs plain radiograms.
1989
In experimentally induced pulmonary contusions, CT (n = 27) and chest X-ray (n = 24) findings were compared with the findings at autopsy. Twenty-seven of 27 (100%) pulmonary contusions were visible by CT immediately after trauma compared with 9 of 24 (37.5%) in the chest X-ray. After 30 min follow-up, 18 of 24 (75%) lesions were seen on the plain film. Five of 24 (21%) contusions escaped detection on conventional radiographs. Computed tomography underestimated lesion size in 5 of 60 (8%) measurements, conventional radiographs in 21 of 36 (58%) measurements. Pathological examination never revealed a pulmonary contusion that was not demonstrated by CT. Therefore, pulmonary contusion seems unl…
Predictors of early dropout in treatment for gambling disorder: The role of personality disorders and clinical syndromes
2017
Several treatment options for gambling disorder (GD) have been tested in recent years; however dropout levels still remain high. This study aims to evaluate whether the presence of psychiatric comorbidities predicts treatment outcome according to Millon's evolutionary theory, following a six-month therapy for GD. The role of severity, duration of the disorder, typology of gambling (mainly online or offline) and pharmacological treatment were also analysed. The recruitment included 194 pathological gamblers (PGs) to be compared with 78 healthy controls (HCs). Psychological assessment included the South Oaks Gambling Screen and the Millon Clinical Multiaxial Inventory-III. The "treatment fail…
Endoureterotomy with the Lovaco technique for treatment of ureterointestinal strictures: outcomes in an experienced center and factors associated wit…
2021
INTRODUCTION The study aimed to present the outcomes of an endoureterotomy series using the Lovaco technique for the treatment of ureterointestinal strictures. Factors influencing the success or failure of this technique were also determined. MATERIALS AND METHODS Data were collected from all endoureterotomies for ureterointestinal strictures performed in a single-center between 2017 and 2020. Clinical variables and characteristics of the stricture were recorded in each case, and success was defined as the complete resolution of ureterohydronephrosis. Univariate analysis was used to correlate the variables recorded with procedural success or failure. RESULTS A total of 25 patients were recr…
Vascular Endothelial Growth Factor, a Key Modulator of the Anti-Tumor Immune Response
2021
During tumor growth, angiogenesis is required to ensure oxygen and nutrient transport to the tumor. Vascular endothelial growth factor (VEGF) is the major inducer of angiogenesis and appears to be a key modulator of the anti-tumor immune response. Indeed, VEGF modulates innate and adaptive immune responses through direct interactions and indirectly by modulating protein expressions on endothelial cells or vascular permeability. The inhibition of the VEGF signaling pathway is clinically approved for the treatment of several cancers. Therapies targeting VEGF can modulate the tumor vasculature and the immune response. In this review, we discuss the roles of VEGF in the anti-tumor immune respon…
