CHARACTERIZATION OF MOLECULAR ISOFORMS AND ROLE OF THE SURVIVAL MOTOR NEURON (SMN) IN MOTOR NEURONS DISEASES.

2014

La sclerosi Laterale Amiotrofica (SLA) e l'Atrofia Muscolare Spinale (SMA) sono malattie neurodegenerative caratterizzate dalla perdita progressiva dei motoneuroni. La SMA è generalmente causata da delezione in omozigosi o mutazione del gene SMN, che codifica per una proteina ubiquitaria e multifunzionale, altamente espressa nel midollo spinale. La SLA è una malattia che può essere familiare o sporadica.Il 20% dei casi familiari è causato da una mutazione dominante nel gene SOD1. Inoltre ci sono altri geni coinvolti in questa malattia, tra cui FUS e TDP43. Lo scopo principale della tesi è quello di studiare il gene, le isoforme, la localizzazione subcellulare ed i partners molecolari di SMN…

The ALS-FTLD continuum: clinical, genetic and neuropsychological aspects

Alexithymia, burden and resilience in ALS’ caregivers

2017

Living with a progressively disease such as Amyotrophic lateral sclerosis (ALS) has a strong impact on the people affected and on their relatives, who have to tackle the demanding duties of caring for and assisting them (Tramonti et al., 2014). Many factors modulate the levels of burden in ALS’ caregivers: disease related factors, personality related factors, enviromental factors. Dennison et al (2001) showed that alexithymia could to contribute to increasing distress in ALS’ caregivers, but there are very few studies on this. Other studies supporting the role of resilience such as protective factor (Ripamonti, 2015). The aim of the study is to assess the relationship between alexithymia, r…

The Portrayal of Paul's Outer Appearance in the Acts of Paul and Thecla. Re-Considering the Correspondence between Body and Personality in Ancient Li…

2008

AbstractThis essay claims that Paul's description in Acts Paul Thecl. 3, if read against the background of Graeco-Roman physiognomics, i.e., the belief in the coherence between outer appearance and inner qualities of a person, is not derogative as assumed in older research but agreeable. The positive interpretation of Paul's outer appearance is corroborated by an analysis of the reactions he evokes in followers (Onesiphorus, Thecla) as well as opponents (Theoclia, Thamyris). It is demonstrated that Paul's physiognomy corresponds to his apostolic identity.

Formation of a new cell wall by protoplasts of Candida albicans: effect of papulacandin B, tunicamycin and Nikkomycin.

1987

SUMMARY: Incorporation of polysaccharides into the walls of regenerating protoplasts of Candida albicans was followed in the presence of papulacandin B, tunicamycin and nikkomycin. With the first drug, chitin was incorporated normally whereas incorporation of glucans and mannoproteins was significantly decreased. Tunicamycin decreased incorporation of all wall polymers when added at the beginning of the regeneration process but blocked only mannan and alkali-insoluble glucan incorporation when added after 5 h. Nikkomycin inhibited chitin synthesis, and the walls formed by the protoplasts were enriched in alkali-soluble glucan. Pulse-chase experiments suggested that a precursor-product relat…

Antifungal activity of natamycin and development of an edible film based on hydroxyethylcellulose to avoid Penicillium spp. growth on low-moisture mo…

2022

Abstract This study aimed to investigate natamycin's in vitro antifungal activity against Penicillium strains and determine its antifungal effect on Mozzarella cheese slices contaminated with P. commune. Besides, the residual content of natamycin in the samples was assessed during the storage. Natamycin was either sprayed on the cheese surface or incorporated into an edible hydroxyethylcellulose film at concentrations of 0, 0.25, 0.5, and 1 mg/dm2. Natamycin showed an antifungal effect against all Penicillium strains with MIC values ranging from 1.6 to 3.1 μg/mL and MFC values ranging from 12.5 to 200.0 μg/mL. Moreover, both applied techniques significantly (p ≤ 0.05) reduced the population…

Identification of a mannoprotein present in the inner layer of the cell wall of Saccharomyces cerevisiae.

1997

Cell wall extracts from the double-mutant mnn1 mnn9 strain were used as the immunogen to obtain a monoclonal antibody (MAb), SAC A6, that recognizes a specific mannoprotein--which we have named Icwp--in the walls of cells of Saccharomyces cerevisiae. Icwp runs as a polydisperse band of over 180 kDa in sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of Zymolyase extracts of cell walls, although an analysis of the secretory pattern of the mannoprotein shows that at the level of secretory vesicles, it behaves like a discrete band of 140 kDa. Immunofluorescence analysis with the MAb showed that Icwp lies at the inner layer of the cell wall, being accessible to the antibody on…

Incorporation of specific wall proteins during yeast and mycelial protoplast regeneration in Candida albicans

1994

The kinectics of incorporation of two precursor mannoproteins into the regenerating cell wall of Candida albicans protoplasts have been followed at 28°C and 37°C using two monoclonal antibodies specific for protein epitopes (MAb 1B12 and 4C12) as probes. Both molecules were secreted from the beginning of the regeneration process, and their incorporation was retarded significantly. Analysis of the secreted materials by Western immunoblotting with MAb 1B12 allowed the identification of two closely migrating bands at apparent Mr higher than 170 kDa and significant amounts of a highly polydisperse material of even greater molecular mass. Some of these mannoproteinaceous species carried both N- …

Wall formation by Candida albicans yeast cells: synthesis, secretion and incorporation of two types of mannoproteins.

1993

SUMMARY: The mannoprotein components solubilized from the walls of Candida albicans blastoconidia following degradation of the glucan network with β-glucanase (Zymolyase) have higher molecular masses than their probable precursors present in the supernatant of regenerating protoplasts. It therefore appears that the mannoproteins are released from the walls as part of supramolecular complexes. Immunological analysis using both polyclonal and monoclonal antibodies has demonstrated the probable relationship between molecules found in a mixed membrane preparation, those secreted by regenerating protoplasts, and those present in yeast cell walls. Some mannoproteins secreted by protoplasts incuba…
