Gli intellettuali e la riforma della scuola: un dibattito sulle pagine di «Rinascita»

2010

The author analyzes, from the Second World War, the debate around school reform born on the pages of «Rinascita». The protagonists were scholars of the caliber of Marchesi L. Lombardo Radice, Banfi and enlargement of the main issues focused around education for the working classes as a means of social ascent (and here he became interested Lombardo Radice). They discussed also the opportunity to bring the school post primary the model of classical humanistic culture or adapt to technical requirements of the manufacturing world. On the pages of «Rinascita» these issues were discussed for many years with great interest.

Adolescenze in territori ad alta densità mafiosa: il punto di vista degli insegnanti

Autophagic response to strenuous exercise in mouse skeletal muscle fibers.

1984

Strenuous physical exercise induces necrosis of skeletal muscle fibers and increases lysosomal enzyme activities in surviving muscle fibers. This study examines the ultrastructural basis of the stimulation of the lysosomal system in mouse vastus medialis muscle during the appearance and repair of exercise-induced (9 h of running) injuries. Necrotic fibers appeared the day after exercise and an inflammatory response with the replacement of necrotic fibers by phagocytes was highest 2-3 days after exertion. Ultrastructural study of surviving muscle fibers revealed numerous autophagic vacuoles, residual bodies, and spheromembranous structures at the periphery of myofibers, especially in fibers …

Childhood neuromuscular disease with rimmed vacuoles

1986

A 5-year-old boy suffered from a slowly progressive non-familial neuromuscular disease, clinically marked by generalised muscle weakness, atrophy and hypotonia, a "myopathic" EMG and mildly elevated CK values. His gastrocnemius muscle showed marked myopathy, type I fibre predominance, and numerous "rimmed" vacuoles. This boy's condition is regarded as a childhood neuromuscular disease with rimmed vacuoles.

Studies on vinblastine-induced autophagocytosis in mouse liver

1980

The origin of the membranes of autophagic vacuoles (AV) and acquisition of acid phosphatase into AV's were studied in vinblastine-induced autophagocytosis (VBL, 50 mg/kg, i.p.) in mouse hepatocytes. Using unbuffered OsO4, very intense staining was observed in the outer cisternae of the Golgi apparatus and also frequently in the cavity between the double membranes obviously destined to form AV's as well as in the cavity between the double membranes of newly formed AV's. There may occur a transformation process in the membranes limiting an AV analogous to that observed at the Golgi cisternae. The transformation of the outer AV membrane occurs independently of fusion with lysosomes. Inosine di…

A multi-centre clinico-genetic analysis of the VPS35 gene in Parkinson disease indicates reduced penetrance for disease-associated variants

2012

Abstract: Background Two recent studies identified a mutation (p.Asp620Asn) in the vacuolar protein sorting 35 gene as a cause for an autosomal dominant form of Parkinson disease. Although additional missense variants were described, their pathogenic role yet remains inconclusive. Methods and results We performed the largest multi-center study to ascertain the frequency and pathogenicity of the reported vacuolar protein sorting 35 gene variants in more than 15,000 individuals worldwide. p.Asp620Asn was detected in 5 familial and 2 sporadic PD cases and not in healthy controls, p.Leu774Met in 6 cases and 1 control, p.Gly51Ser in 3 cases and 2 controls. Overall analyses did not reveal any sig…

Determination of cytokeratins 1, 13 and 14 in oral lichen planus

2014

Cytokeratins (CK) are molecules of the cytoskeleton that contribute to the cellular differenciation. We studied the expression of CK1, CK13 and CK14 in thirty-three patients with OLP. The biopsied lesions were located in the dorsal surface of the tongue, the palatal keratinized mucosa and the nonkeratinized buccal mucosa. Objectives: This study aimed to determine the expression of CK1, CK13 and CK14 in oral lichen planus (OLP) and its relations with: clinical patterns, prognosis, drugs and tobacco intake and histopathological features. Study Design: Immunohistochemical analysis, retrospective, descriptive, observational and no randomized study. Results: No significant difference was observe…

Ultrastructural Pathology of Eccrine Sweat Gland Epithelial Cells in Globoid Cell Leukodystrophy

1993

Three of four children were recognized by deficient β-galactocerebrosidase activities as having globoid cell leukodystrophy inclusions in sweat gland epithelial cells, similar in ultrastructure to those seen in Schwann cells. This observation in globoid cell leukodystrophy emphasizes the need to include sweat gland epithelial cells in examinations of skin in globoid cell leukodystrophy, as well as in any neurometabolic disorder. ( J Child Neurol 1993;8:171-174).

Fine structural features of the cerebral microvasculature in hydrocephalic human infants: correlated clinical observations.

1989

Four of 30 human cerebral cortex biopsies from infants ranging from four days to about ten years treated for hydrocephalus by shunt operations are described paying special attention to the vascular structures. The biopsy specimens were studied in semi-thin and ultrathin sections. Attention is drawn to the role of pinocytotic vesicles found in capillaries and smaller vessels as a possible transcellular route for the hydrocephalic oedema resolution. No intercellular dehiscences or the so called blisters were observed. With the passage of time, the number of membrane bound vesicles increased and arrays of pinocytotic vesicles were discernible both on the abluminal as well as luminal aspect of …
