Introduction: The lymphatic system is a multifaceted regulator of tissue homeostasis and an integral part of immune responses. Previous studies had shown that subsets of lymphatic endothelial cells (LEC) express , an essential component of humoral innate immunity and tissue homeostasis.
Methods: In the present study using whole-mount imaging and image-based morphometric quantifications, -targeted mice and functional analysis, we investigated the involvement of PTX3 in shaping and function of the lymphatic vasculature.
Objectives: To test the performance of ex vivo fluorescence confocal microscopy (FCM; Vivascope 2500M-G4), as compared to intra-operative frozen section (IFS) analysis, to evaluate surgical margins during robot-assisted radical prostatectomy (RARP), with final pathology as the reference standard.
Methods: Overall, 54 margins in 45 patients treated with RARP were analysed with: (1) ex vivo FCM; (2) IFS analysis; and (3) final pathology. FCM margins were evaluated by two different pathologists (experienced [M.
We designed a phase 3, prospective, randomized trial to evaluate the impact of augmented reality and augmented reality frozen section analysis in reducing the rates of positive surgical margins after robot-assisted radical prostatectomy.

The National Center for Oncological Hadrontherapy (CNAO) is the only Italian facility able to accelerate both protons and carbon ions for oncological treatment and research.
Methods: To summarise and critically evaluate state-of-the-art knowledge on the application of carbon ion radiotherapy in oncological settings, the authors conducted a literature search till December 2022 in the following electronic databases: PubMed, Web of Science, MEDLINE, Google Scholar, and Cochrane.
The recent advancements in breast cancer precision medicine have highlighted the urgency for the precise and reproducible characterization of clinically actionable biomarkers. Despite numerous standardization efforts, biomarker testing by conventional methodologies is challenged by several issues such as high inter-observer variabilities, the spatial heterogeneity of biomarkers expression, and technological heterogeneity. In this respect, artificial intelligence-based digital pathology approaches are being increasingly recognized as promising methods for biomarker testing and subsequently improved clinical management.

Here, we report that D6 is expressed in Kaposi sarcoma (KS), a tumor ontogenetically related to the lymphatic endothelium. Both in human tumors and in an experimental model, D6 expression levels were inversely correlated with tumor aggressiveness and increased infiltration of proangiogenic macrophages.

Objectives: To evaluate the risk factors of liver fibrosis progression (LFP) and to investigate the role of antiretroviral therapy (ARV) in HIV/HCV patients who underwent paired liver biopsy.
We evaluated histologic results for surgical left maze with an high-intensity focused ultrasound (HIFU) energy source. Two patients came to our attention 6 and 48 months, respectively, after ablation concomitant to a valve procedure. Tissue specimens, obtained from the lesion site on the mitral isthmus and from the "box lesion" around the pulmonary veins were analyzed histologically.

Aim: We analysed the effects of HSCT on the immune response of patients treated for moderate-severe Crohn's disease, refractory or intolerant to multiple drugs.
Methods: Unselected peripheral blood stem cells were collected after mobilisation with cyclophosphamide (CTX) and G-CSF.
Vagal activity has protective effects in ischemic heart disease. We tested whether vagal stimulation (VS) could modulate the inflammatory reaction, a major determinant of cardiac injury after ischemia/reperfusion. Four groups of male rats underwent myocardial ischemia (30 minutes) and reperfusion (24 hours).

We used the National UK IBD audit tool to compare the organisation and process of IBD care between services in Oxford (UK) and Milan (Italy), as a pilot study to evaluate its application outside national boundaries.
Methods: Clinical and demographic data of patients with CD and UC, consecutively admitted during a 2month period, were collected and compared between the centres, to each other and to the UK IBD standards obtained by previous audit analyses performed in Oxford in 2006.
We retrospectively evaluated autopsy-proven invasive fungal infections (IFIs) in patients with AIDS who died between 1984 and 2002. IFIs were identified in 297 (18.2%) of 1,630 autopsies.
View Article and Find Full Text PDFJC virus (JCV) is a human polyomavirus that causes progressive multifocal leukoencephalopathy (PML), a fatal demyelinating disease that mainly affects immunocompromised subjects. Since its discovery, PML has been considered a rapidly progressing fatal disease; however, amino acid substitutions in the capsid viral protein have recently been tentatively associated with changes in PML clinical course. In order to provide more insight to PML pathogenesis and identify potential prognostic markers, seven cerebrospinal fluid (CSF) samples and four brain autopsy samples were collected from patients afflicted with PML with different clinical courses (fast- and slow-progressing), and the JCV VP1 coding region was amplified, cloned, and sequenced.

Former results identified low cerebral complement levels as one cause for insufficient immune reaction. Therefore we studied cerebral complement expression after fungal invasion and investigated putative mechanisms of Aspergillus spp to cope with the complement-induced selection pressure.
View Article and Find Full Text PDFThe chemokine system includes at least three "silent" receptors, DARC, D6 and CCX CKR, with distinct specificity and tissue distribution. D6 binds most inflammatory, but not homeostatic, CC chemokines and shuttles in a ligand-independent way from the plasma membrane to endocytic compartments where chemokines are targeted to degradation. In vitro and in vivo evidence, including results with gene-targeted mice, is consistent with the view that D6 acts as a decoy and scavenger for inflammatory CC chemokines.

The modulation of selected genes was validated by real-time PCR, Northern blot, and protein production. IL-10 regulated in DC the expression of a limited number of genes, including IL-7, the receptors for transferrin and vitamin D(3), structural matrix proteins, and signal transduction elements.

The progressive accumulation of GL in tissues results in the clinical manifestations of the disease, that are more evident in hemizygous males, and include characteristic skin lesions (angiokeratomas), neurological symptoms (acroparesthesia), ocular features (cornea verticillata), cardiac involvement (left ventricular enlargement, conduction abnormalities), cerebrovascular manifestations (thromboses, hemorrhage, etc.), and kidney involvement with progression to end-stage renal failure (ESRF).
