Autophagy
2021
In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide…
Specie vegetali mediterranee impiegate nei sistemi di fitodepurazione
2010
L’acqua è un bene essenziale che ha da sempre influenzato la localizzazione degli insediamenti antropici, permettendone lo sviluppo e garantendone sussistenza, igiene e forza motrice. L’utilizzo di questa risorsa, sempre più preziosa e vulnerabile, non sempre risponde a criteri di salvaguardia, conservazione e miglioramento della qualità e della quantità. I frequenti periodi di siccità e i processi di inquinamento hanno determinato nel tempo una progressiva riduzione delle risorse idriche disponibili nei diversi settori di impiego e motivato l’esigenza di trovare nuove soluzioni per una migliore gestione della “risorsa acqua”. Tra le tecnologie proponibili a basso impatto ambientale, soprat…
Imaging features of histological subtypes of hepatocellular carcinoma: Implication for LI-RADS
2021
Background & Aims The histopathological subtypes of hepatocellular carcinoma (HCC) are associated with distinct clinical features and prognoses. This study aims to report Liver Imaging Reporting and Data System (LI-RADS)-defined imaging features of different HCC subtypes in a cohort of resected tumours and to assess the influence of HCC subtypes on computed tomography (CT)/magnetic resonance imaging (MRI) LI-RADS categorisation in the subgroup of high-risk patients. Methods This retrospective institutional review board-approved study included patients with resected HCCs and available histopathological classification. Three radiologists independently reviewed preoperative CT and MRI exams. T…
Case report supporting that the Barber-Say and ablepharon macrostomia syndromes could represent one disorder.
2009
We report on a 7-year-old girl with unequivocal features of Barber-Say syndrome (BSS): generalized hypertrichosis especially at the back, dry lax skin, macrostomia, thin lips, cup-shaped ears, bulbous nose, hypoplastic nipples, and abnormal external genitalia. She also demonstrated conductive hearing impairment and microblepharon. BSS has been reported with ectropion (not present in our patient), but ablepharon and microblepharon (i.e., absent or hypoplastic eyelids) have always been considered as hallmarks of ablepharon macrostomia syndrome (AMS). This is the first report of microblepharon in BSS. Other authors have discussed that BSS and AMS could possibly represent one syndrome, and our …
Canakinumab in systemic juvenile idiopathic arthritis: real-world data from a retrospective Italian cohort
2021
Abstract Objective The objective of this study was to use real-world data to evaluate the effectiveness and safety of canakinumab in Italian patients with systemic JIA (sJIA). Methods A retrospective multicentre study of children with sJIA was performed. Clinical features, laboratory parameters and adverse events were collected at baseline, and 6 and 12 months after starting canakinumab. The primary outcome measure of effectiveness was clinically inactive disease (CID) off glucocorticoids (GCs) treatment at 6 months. Results A total of 80 children from 15 Italian centres were analysed. Of the 12 patients who started canakinumab in CID while receiving anakinra, all maintained CID. Of the 68 …
Toll-like receptor 5 in obesity: The role of gut microbiota and adipose tissue inflammation
2015
Objective This study aimed at establishing bacterial flagellin-recognizing toll-like receptor 5 (TLR5) as a novel link between gut microbiota composition, adipose tissue inflammation, and obesity. Methods An adipose tissue microarray database was used to compare women having the highest (n = 4, H-TLR) and lowest (n = 4, L-TLR) expression levels of TLR5-signaling pathway genes. Gut microbiota composition was profiled using flow cytometry and FISH. Standard laboratory techniques were used to determine anthropometric and clinical variables. In vivo results were verified using cultured human adipocytes. Results The H-TLR group had higher flagellated Clostridium cluster XIV abundance and Firmicu…
n-3 Fatty Acids Modulate T-Cell Calcium Signaling in Obese Macrosomic Rats
2004
Objective: We investigated the effects of a diet containing EPAX-7010, rich in PUFAs such as eicosapentaenoic acid [20:5(n-3)] and docosahexaenoic acid [22:6(n-3)], i.e., a PUFA/EPAX regimen, on T-cell activation in diabetic pregnant rats and their obese pups. Research Methods and Procedures: Mild hyperglycemia in pregnant rats was induced by intraperitoneal injection of streptozotocin on Day 5 of gestation. T-cell blastogenesis was assayed by using 3H-thymidine, whereas intracellular free calcium concentrations ([Ca2+]i) were measured by using Fura-2 in diabetic pregnant rats and their obese offspring. Results: Concavalin-A-stimulated T-cell proliferation was decreased in both pregnant dia…
Age-related changes in cholesterol metabolism in macrosomic offspring of rats with streptozotocin-induced diabetes.
2001
The aim of this study was to determine the impact of diabetic macrosomia on cholesterol and lipoprotein metabolism. Age-related changes in the activities of serum LCAT, hepatic HMG-CoA reductase, cholesterol 7α-hydroxylase, and ACAT, the major enzymes involved in cholesterol metabolism, were determined in macrosomic offspring of streptozotocin-induced diabetic rats. Hepatic, serum, and lipoprotein cholesterol contents were also examined. Mild hyperglycemia in pregnant rats was induced by intraperitoneal injection of streptozotocin (40 mg/kg body weight) on day 5 of gestation. Control pregnant rats were injected with citrate buffer. At birth, macrosomic pups had higher serum, LDL-HDL1, and H…
Changes in serum lipid and lipoprotein concentrations and compositions at birth and after 1 month of life in macrosomic infants of insulin-dependent …
1999
The aim of this study was to determine whether macrosomia related to maternal diabetes alters lipoprotein metabolism and whether these abnormalities still persist or regress after 1 month of life. Serum lipoprotein compositions and concentrations as well as serum lipid fatty acid compositions were investigated in macrosomic infants (birth weight = 4840 +/- 105 g at term) of insulin-dependent diabetic mothers at birth and after 1 month of life, and were compared to those of control infants (birth weight = 3400 +/- 198 g at term) of healthy mothers. Compared to controls, at birth, macrosomic newborns had higher serum lipids, apolipoprotein A-I and B-100, and lipoprotein (very low density lipo…
