The abdominal wall incisional hernia repair in cirrhotic patients
2018
BACKGROUND: The incidence of abdominal wall hernia in cirrhotic patients with ascites is between 20 and 40%. Controversies regarding the treatment modality and surgical timing of abdominal wall incisional hernia repair in cirrhotic patients remain. The study proposed wants to analyze the abdominal incisional hernia repair in cirrhotic patients with ascites performed in a single center to determine post-operative morbidity, mortality and complication rate. PATIENTS AND METHODS: Cirrhotic patients with abdominal incisional hernia that underwent surgical operation for abdominal wall hernia repair at the "Policlinico Paolo Giaccone" at Palermo University Hospital between January 2015 and Decemb…
MRI abnormalities following repeated and incoming seizures.
2010
Abstract Neuroimaging, an important diagnostic tool frequently used in the evaluation of patients with epilepsy, has mainly the aim to identify structural abnormalities needing a treatment and to contribute to the definition of the aetiology. Brain magnetic resonance imaging (MRI) in epilepsy is more sensitive than computerized tomography (CT) scan for detecting abnormalities. Status epilepticus (SE) and repeated incoming seizures may determine extensive and transient or long lasting pronounced MRI changes. We describe a case of a 41-year-old woman with a history of brain neoplasm, whose contrast-enhanced MRI images following repeated and incoming seizures were characterized either by rever…
Clinical, immunological, and molecular analysis in a large cohort of patients with X-linked agammaglobulinemia: an Italian multicenter study
2002
A questionnaire-based retrospective clinical and immunological survey was conducted in 73 males with a definite diagnosis of X-linked agammaglobulinemia based on BTK sequence analysis. Forty-four were sporadic and 29 familial cases. At December 2000, the patients' ages ranged from 2 to 33 years; mean age at diagnosis and mean duration of follow-up were 3.5 and 10 years respectively. After the mid-1980s all but 2 were on intravenous immunoglobulin (IVIG) substitution therapy, with residual IgG >500 mg/dl in 94% of the patients at the time of enrollment. Respiratory infections were the most frequent manifestation both prior to diagnosis and over follow-up. Chronic lung disease (CLD) was prese…
Chemoprotective effect of carotenoids from Lycium barbarum L. on SH-SY5Y neuroblastoma cells treated with beauvericin
2020
Goji berry has recently been introduced in Mediterranean diet and its consumption is increasing. This study aims to determine cytoprotection of lutein (LUT), zeaxanthin (ZEAX) and goji berry extract (GBE) rich in carotenoids against Beauvericin (BEA)-induced cytotoxicity on SH-SY5Y neuroblastoma cells. Both carotenoids and GBE showed cytoprotective effects. Cytoprotection was evaluated by simultaneous combination of the two xanthophylls LUT and ZEAX with BEA, as well as using pre-treatment assays. The highest protective effect occurred in 16%, 24% and 12% respectively for LUT, ZEAX and LUT + ZEAX incubating simultaneously with BEA, while by pre-treatment assay LUT showed a cytoprotection ef…
Cytoprotective effects of carotenoids-rich extract from Lycium barbarum L. on the beauvericin-induced cytotoxicity on Caco-2 cells.
2019
Abstract In this work, the cytotoxicity of Beauvericin (BEA), lutein (LUT), zeaxanthin (ZEAX) and goji berries extract (GBE) rich in carotenoids, was investigated, as well as cytoprotective effects of these carotenoids against BEA induced-cytotoxicity on Caco-2 cells. Cytotoxicity was carried out using MTT and protein content (PC) assays during 24 and 48 h of exposure. Only BEA showed cytotoxic effect obtaining a reduction in cell proliferation range from 6.5 to 92.8%. Simultaneous combination of LUT and ZEAX with BEA slightly increased cell proliferation compared to BEA tested alone. LUT, ZEAX and GBE showed cytoprotective effects against cytotoxicity induced by BEA on Caco-2 cells. Pre-tr…
Immune pathway upregulation and lower genomic instability distinguish EBV-positive nodal T/NK-cell lymphoma from ENKTL and PTCL-NOS
2022
Primary Epstein-Barr virus (EBV)-positive nodal T/NK-cell lymphoma (PTCL-EBV) is a poorly understood disease which shows features resembling extranodal NK/T-cell lymphoma (ENKTL) and is currently not recognized as a distinct entity but categorized as a variant of primary T-cell lymphoma not otherwise specified (PTCL-NOS). Herein, we analyzed copynumber aberrations (n=77) with a focus on global measures of genomic instability and homologous recombination deficiency and performed gene expression (n=84) and EBV miRNA expression (n=24) profiling as well as targeted mutational analysis (n=16) to further characterize PTCL-EBV in relation to ENKTL and PTCL-NOS. Multivariate analysis revealed that …
mTORC1 activation in B cells confers impairment of marginal zone microarchitecture by exaggerating cathepsin activity
2018
Mammalian target of rapamycin complex 1 (mTORC1) is a key regulator of cell metabolism and lymphocyte proliferation. It is inhibited by the tuberous sclerosis complex (TSC), a heterodimer of TSC1 and TSC2. Deletion of either gene results in robust activation of mTORC1. Mature B cells reside in the spleen at two major anatomical locations, the marginal zone (MZ) and follicles. The MZ constitutes the first line of humoral response against blood‐borne pathogens and undergoes atrophy in chronic inflammation. In previous work, we showed that mice deleted for TSC1 in their B cells (TSC1(BKO)) have almost no MZ B cells, whereas follicular B cells are minimally affected. To explore potential underl…

Foaming in membrane bioreactor: identification of the causes
2012
The biological foaming was related to the metabolism of certain microorganisms that synthesize and excrete hydrophobic compounds. Recently, by the attention of many researchers the biological foaming in the MBR has attracted, because MBR foam has been also observed in the absence of foam-forming microorganisms, contrarily to conventional activated sludge systems. In this paper the authors investigate the role of EPS and filamentous bacteria analyzing different samples from different MBR pilot plants. In particular, in order to define the macroscopic features and the role of EPS and filamentous bacteria a modified Scum Index (MSI) test was applied. Further a multiple classification of SI was…
Monocyte Distribution Width (MDW) as a biomarker of sepsis: An evidenced-based laboratory medicine approach.
2023
Monocyte Distribution Width (MDW) is a new generation cell blood count parameter providing a measure of monocyte anisocytosis. In the last decades, it has emerged as a reliable biomarker of sepsis in the acute setting, especially emergency department, and intensive care unit. MDW has several advantages over commonly used sepsis biomarkers, including low-cost, ease and speed of measurement. The clinical usefulness of MDW has been established in several studies and some clinical laboratory medicines have already implemented it in their routine. In this article, we describe the analytical and clinical features of MDW to guide its appropriate use in clinical practice by integrating the research…
