Physical and biological properties of electrospun poly(d,l‐lactide)/nanoclay and poly(d,l‐lactide)/nanosilica nanofibrous scaffold for bone tissue en…
2021
Abstract Electrospun scaffolds exhibiting high physical performances with the ability to support cell attachment and proliferation are attracting more and more scientific interest for tissue engineering applications. The inclusion of inorganic nanoparticles such as nanosilica and nanoclay into electrospun biopolymeric matrices can meet these challenging requirements. The silica and clay incorporation into polymeric nanofibers has been reported to enhance and improve the mechanical properties as well as the osteogenic properties of the scaffolds. In this work, for the first time, the physical and biological properties of polylactic acid (PLA) electrospun mats filled with different concentrat…
Effects of conjugated linoleic acid and endurance training on peripheral blood and bone marrow of trained mice
2007
Fat supplements, es- pecially conjugated linoleic acid (CLA), are increasingly popular ergogenic aids among endurance athletes. To evaluate the im- portance of fat supplementation in the practice of endurance sports, we investigated the effects of CLA supplementation on body weight, muscle hypertrophy, peripheral blood composition, and bone marrow composition in healthy, young, endurance- trained mice. Young, healthy mice were subdivided into control, trained, and treated groups, according to their running atti- tudes. Training was performed over a period of 6 weeks on a treadmill, at a gradually increasing duration and speed. CLA- treated groups were gavaged with 0.425 mg·d 1 CLA supplemen…
The Abundance of Tumor-Infiltrating CD8+ Tissue Resident Memory T Lymphocytes Correlates with Patient Survival in Glioblastoma
2022
Glial tumors alone account for 40% of all CNS tumors and present a low survival rate. The tumor microenvironment is a critical regulator of tumor progression and therapeutic effectiveness in glioma. Growing evidence from numerous studies of human solid tumor-infiltrating CD8(+) T cells indicates that tissue-resident memory T cells (TRM) represent a substantial subpopulation of tumor-infiltrating lymphocytes (TILs). Although it is reported that some types of cancer patients with high immune infiltration tend to have better outcomes than patients with low immune infiltration, it seems this does not happen in gliomas. This study aimed to characterize TRMs cells in the glioma tumor microenviron…
Multicomponent Antibiofilm Lipid Nanoparticles as Novel Platform to Ameliorate Resveratrol Properties: Preliminary Outcomes on Fibroblast Proliferati…
2023
The well-being of skin and mucous membranes is fundamental for the homeostasis of the body and thus it is imperative to treat any lesion quickly and correctly. In this view, polyphenols might assist and enhance a successful wound healing process by reducing the inflammatory cascade and the production of free radicals. However, they suffer from disadvantageous physico–chemical properties, leading to restricted clinical use. In this work, a complex mixture of PEGylated lipid, Glyceryl monoester, 18-β-Glycyrrhetinic Acid and Menthol was designed to entrap Resveratrol (RSV) as the active ingredient and further produce lipid nanoparticles (LNPs) by homogenization followed by high-freq…
IL RANK LIGANDO QUALE TARGET TERAPEUTICO NEL TRATTAMENTO DELLE PAZIENTI ANZIANE CON OSTEOPOROSI
2013
Cortical and trabecular bone undergo a continuous and balanced remodeling process, which consists of a phase of resorption, mediated by osteoclasts, and a phase of neoformation mediated by osteoblasts. The activity of both, osteoblasts and osteoclasts, is regulated by the osteocytes, which are the most abundant cells in bone tissue. An imbalance of this process with an excessive resorption activity causes a loss of bone mass and microarchitectural deterioration of the skeleton, with consequent reduction of bone strength and increased risk of fractures. The ligand for the “Receptor Activator of Nuclear Factor Kappa- B” (RANK-L), a protein expressed by osteoblasts, plays a fundamental role in…

GESTIONE PERIOPERATORIA DEI BAMBINI AFFETTI DA NEUROBLASTOMA E IPERTENSIONE TUMORE-DIPENDENTE: STUDIO DEL GRUPPO ITALIANO DI CHIRURGIA ONCOLOGICA PED…
2015
Il Neuroblastoma (NB) con sintomatologia ipertensiva riveste un’esigua percentuale dei tumori neuroblastici trattati ogni anno, attualmente in letteratura esistono unicamente due studi (1,2), che riportano un’incidenza di sintomatologia ipertensiva del 10-19% dei casi. Il follow-up dei pazienti studiati risulta breve, inoltre il meccanismo fisiopatologico non è stato tuttora dimostrato, ipotizzando una combinazione tra la compressione del peduncolo vascolare renale e la secrezione di catecolamine urinarie. Per quanto riguarda il management intra-operatorio, che può risultare difficoltoso a causa di picchi iper\ipotensivi durante la manipolazione della massa, esistono unicamente case reports…
Congenital malformations.
2012
Congenital malformations are single or multiple defects of the morphogenesis of organs or body districts identifiable at birth or during the intrauterine life. Their global birth prevalence is about 2–3%. Both genetic and environmental factors, as well as their combination in a multifactorial contest, may induce congenital defects. Congenital malformations may be classi- fied on the basis of clinical, etiologic as well as pathogenetic criteria. Relevant diagnostic and therapeutic tools have been progressively improving in the last decades, contributing to a better identification and a reduction of long-term morbidity and mortality of these patients. A correct identification of a congen- ita…
