Speranza","doi":"10.36253/ijae-13801","DOIUrl":"https://doi.org/10.36253/ijae-13801","url":null,"abstract":"Inflammatory bowel disease (IBD) is a chronic pathology characterized by extensive inflammation, which causes a functional alteration of the intestinal barrier. Today most of the drugs applied for IBD have adverse consequences. In this scenario, the development of new therapeutic agents for the treatment of IBD is necessary. A new approach to develop effective therapeutic strategies is the study of natural compounds with anti-inflammatory properties. Saffron petals contain flavonolic glycosides (kaempferol), carotenoids (crocin and crocetin) and anthocyanin pigments, with antioxidant and anti-inflammatory activity. Recently, kaempferol and crocin identified in Saffron Petal Extract (SPE), has been able to reduce oxidative stress in intestinal epithelial cells. Our aim was to evaluate the therapeutic potential of SPE on inflamed human intestinal Caco2 cells that mimic the intestinal microenvironment. We have demonstrated that SPE, down-regulating the expression of the ubiquitine FBW7, inhibits the degradation of the IKB-α subunit and keeps NF-κB in the inactive state. This leads downstream to a reduced activation of inducible molecules (iNOS, COX-2 and HO-1) involved on intestinal inflammatory process. In conclusion, since FBW7 increases in colon tissue of IBD patients, SPE may represent an attractive and promising supplementary treatment for the therapeutic management of IBD with conventional therapies.","PeriodicalId":14636,"journal":{"name":"Italian journal of anatomy and embryology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49497185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The history of theoretical bone physiology has been evaluated in detail. The modern theory of bone physiology is consistent with the integration among regional acceleratory phenomenon, Utah paradigm, and mechanostat hypothesis: bone modelling and remodelling respond to pleiotropic stimuli. To date, several histologic, in silico and in vitro studies in implant dentistry corroborate the theories about bone physiology. However, each evaluation method has pros and cons, providing analytical data that can only be used to esteem the in vivo behaviour of the bone-implant system. There is the need of further research with highly validated methods and improved measurement devices, to better integrate data form different research types. This would progressively lead to more structured comprehension of the in vivo performance of dental implants and their surrounding bone, and hopefully to a clear definition of the impact of loading on implant failure.","PeriodicalId":14636,"journal":{"name":"Italian journal of anatomy and embryology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46480534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acute hypoxic exposure can result in reversible acclimatization in heart tissue, maintaining a good systemic oxygen supply, while chronic hypoxic exposure leads to tissue damage exacerbating hypoxia-induced cardiac dysfunction. Extracellular vesicles (EVs) are small membrane vesicles, of the order of nanometers, secreted by different cell types. EVs are mediators of intercellular communication in both physiological and pathological conditions. EVs produced by oral-cavity-derived Mesenchymal Stem Cells (MSCs), including human gingival mesenchymal stem cells, have pro-angiogenic and anti-inflammatory effects. For this reason, the EVs can be identify as a new therapeutic potential for tissue regeneration. The aim of the present work was to evaluate the effect of treatment with EVs produced by human gingival mesenchymal stem cells (hGMSCs) on an in vitro model of HL-1 cardiomyocytes cultured under acute hypoxia state (0,2% hypoxia) followed by normoxia conditions. The HIF-1α expression was downregulate with EVs treatment. EVs could represent an innovative platform to prevent the hypoxic damages.","PeriodicalId":14636,"journal":{"name":"Italian journal of anatomy and embryology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46375677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, therefore, a holistic diagnostic-therapeutic approach has been developed in the management of odontogenic infections by carrying out a careful systemic history of the patient who has an infectious condition in the oral cavity. The early detection of systemic sepsis conditions was facilitated using serum biomarkers such as PCR, Procalcitonin (PCT) and Presepsin (PSEP) in hospital emergency rooms. However, even if used in combination, their diagnostic accuracy is such as to suggest the importance of researching new, more specific, and sensitive biomarkers. A total of 9 articles was analyzed to investigate the use of the PSEP as biomarker in the maxillo-facial region infections and including only English-language articles and the electronic search of publications from 1 January 2017 to 31 December 2021.

Helicobacter pylori (Hp) infection is an important risk factor for GC. However, the etiology of the tumor is multifactorial, since only 1-3% of infected patients develop cancer. Therefore, attention should be focused on the role of microbiota in gastric tumorigenesis since in some studies an alteration of the microbiota in GC has been shown. Fusobacterium nucleatum (Fn) has been found in biopsies of patients with GC. However, since its role is not clearly established, this study investigated the effects of Fn infection on the human gastric adenocarcinoma cell line AGS. Our results showed that Fn co-localized at level of the plasma membrane demonstrating the ability of Fn to adhere to AGS cells. In addition, increases in incubation times were associated with its intra-cellular localization with loss of the classic curved rod shape. Interestingly, Fn determined a greater capacity of cell migration compared to untreated AGS cells. Moreover, IL-4 expression significantly increased in Fn infected GC cells. Since cancer cell migration is an integral component of the metastatic process, additional studies are needed to better understand the mechanisms underlying the Fn/host interaction.","PeriodicalId":14636,"journal":{"name":"Italian journal of anatomy and embryology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46561472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the 16th Century, ceroplastic became also an essential tool for medical education thanks to the creation of the first anatomical wax models. For centuries, anatomists have worked with artists with the aim of producing faithful and long-lasting wax artefacts that reproduce physiological and/or pathological conditions. Important figures such as Ercole Lelli and Anna Morandi Manzolini refined the techniques of the anatomical wax modelling and created works that are to date preciously conserved. The scientific and didactic value of these works was indisputable, for wax anatomical models have deeply facilitated the education of medical students in that time. Nowadays, a similar impact on medical education is given by new technologies such as augmented reality, that allows the addition of virtual contents to tangible anatomical 3D models. Under this light, anatomical wax models and augmented reality can be compared as two innovative tools that have changed the history of anatomical teaching.","PeriodicalId":14636,"journal":{"name":"Italian journal of anatomy and embryology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43660889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beyond burials from the tomb owner and his family from the Old Kingdom, the complex was re-used until the Late Period. The excavated material presented the human remains of at least 73 individuals. Unfortunately, initial excavations had collected and mixed individual burials, so that individual identification in most skeletons was not possible. Later excavations presented complete individual burials. The custom typical of the New Kingdom until the Late Period of transnasal trephination offered, even with the mixed burials, a collection of 23 disturbed adults’ skulls (New Kingdom until Late Period) and 33 skulls of undisturbed adults (Old Kingdom). In these two groups sex ratios were fairly balanced. Most adult individuals died between 20 to 30 years. There were relatively few immature burials and a single skeleton was that of a 7th lunar month fetus, an obvious stillbirth; total number of immature was 10 (17.8%). Numerous paleopathological observations indicated the considerable impact of living conditions and health. There were 12 cases with healed traumatic sequelae including one with a healed ankylosed fracture of the knee and another with a fracture of the humerus, three cases of nonspecific osteomyelitis, three cases highly suggestive of spinal tuberculosis, one with evidence of metabolic bone disease from vitamin deficiency, and two cases with malignant bone tumours; one with multiple metastases of the vertebrae, and the other chondrosarcoma of the pelvis. Also, typical pathological changes were seen in teeth and jaws. Finally, the rate of osteoarthrosis of large joints and that of spondylosis suggest significant work load. These findings indicate various ailments either due to heavy work load (arthrosis and spondylosis, traumatic sequelae), or to the living conditions (tooth abrasion by sand ingestion; tuberculosis due to foundation of settlements and townships), metabolic osteopathies possibly due to parasitic diseases and/ or malnutrition. These skeletal remains therefore contribute to our understanding of ancient Egyptian life and diseases.","PeriodicalId":14636,"journal":{"name":"Italian journal of anatomy and embryology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42254353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
