Stimulation with carbachol alters endomembrane distribution and plasma membrane expression of intracellular proteins in lacrimal acinar cells.
2000
The events that lead to Sjogren's autoimmune processes in the lacrimal gland remain poorly understood. The acinar cell's responses to acute cholinergic stimulation include release of secretory products across the apical plasma membrane (apm) and a number of processes related to traffic between endomembrane compartments and the basal-lateral plasma membranes (blm), such as recruitment of Na, K-ATPase, accelerated recycling, and accelerated transcytosis of secretory IgA. We tested the hypothesis that stimulation-induced acceleration of endomembrane traffic is accompanied by changes in compartmentation and increased blm expression of proteins that are normally sequestered in endomembrane compa…
Lysosomal trafficking in rat cardiac myocytes.
1990
By immunolabeling of cryosections, we have characterized in rat cardiac myocytes the cation-independent mannose-6-phosphate receptor (MPR), a lysosomal membrane glycoprotein, lgp120, and a lysosomal enzyme, MEP (homologous to cathepsin L). Most of the MPR label was located in large membrane-filled structures (MPR structures) in large clusters of mitochondria adjacent to but distinct from the Golgi complex. Lpg120 and MEP showed typical lysosomal localization throughout the cell, often associated with regions that appeared to contain autophagosome-like structures. In addition, MEP and lgp120 co-localized within MPR structures. MEP and MPR were localized inside the lumen of MPR structures. M…

Relationships between stomatognathic and oculomotor systems in the postural determinism
2009
Objectives To establish if oculomotor apparatus, stomatognathic apparatus and postural system are someway related. Materials and methods Ocular deficit, postural stabilization, head inclination and rotation, shoulder position and dental class were assessed by convergence test, cover test, postural and stomatognathic examination in a sample of 22 patients with ocular disease (convergence deficit, strabismus and heterophoria) aged from 10 to 18 years. Results In patients with convergence's deficit, body axis deviated to left (65%) and head inclination to right (65%), right shoulder was higher (68%) and I dental class was observed (49%); in patients with strabismus, body axis deviated to left …
La polizia in Italia. Una storia complessa
2021
I sette contributi che compongono il dossier sono l'esito di un seminario tenutosi presso l'Università degli studi di Milano nell'ambito delle attività del Cepoc (Centro per lo studio delle polizie e del controllo del territorio). In quella occasione si sono discussi quattro volumi di recente pubblicazione (editi tra 2018 e 2019) aventi per oggetto diversi aspetti di storia delle polizie in Italia in età contemporanea, con la partecipazione sia degli autori e curatori dei volumi, sia di studiosi della materia. Ne esce un quadro articolato e problematizzato degli indirizzi secondo i quali in Italia si va consolidando una storiografia dedicata a questi temi, sin qui relativamente trascurati c…
La buona morte di Filippo iv e la proclamazione del suo successore. Un modello di comunicazione in età barocca
2021
Nella prima età moderna, l’importanza attribuita dalla società del tempo al rituale funebre ha portato l’attenzione degli studiosi sulle pratiche funerarie e sugli apparati effimeri commissionati agli artisti di corte, con il susseguirsi di numerosi studi che hanno analizzato il fenomeno sotto vari punti di vista, trovando spesso una contestualizzazione territoriale della produzione effimera, esaminando scrupolosamente le cerimonie funebri della monarchia spagnola: Il trattamento dei corpi, imbalsamazione, l’abito dei monarchi, il tipo di sepoltura, il corteo funebre, le cappelle ardenti o i modi di mostrare il dolore. Un impegno comune inizia ad apparire dalla serie di belle morti, che acc…
In the name of security : Governmentality apparatus in a multilingual mine in Arctic Finland
2021
This critical sociolinguistic study explores how mining work is governed in the name of security in a mine in Arctic Finland. Although the mining industry is dominated by multinational corporations, mines themselves tend to be concentrated in peripheries where a mobile and multilingual workforce is recruited. Mining is a high-risk business: industrial accidents and environmental damage can be severe. Discursive practices play a crucial role in risk management. In this study, the nexus of language, security, and production in mining work is analyzed by applying the Foucauldian concept of 'governmentality'. The data comprise ethnographic observations, work-related documents, and interviews co…

Advances in Nanoliposomes Production for Ferrous Sulfate Delivery
2020
In this study, a continuous bench scale apparatus based on microfluidic fluid dynamic principles was used in the production of ferrous sulfate-nanoliposomes for pharmaceutical/nutraceutical applications, optimizing their formulation with respect to the products already present on the market. After an evaluation of its fluid dynamic nature, the simil-microfluidic (SMF) apparatus was first used to study the effects of the adopted process parameters on vesicles dimensional features by using ultrasonic energy to enhance liposomes homogenization. Subsequently, iron-nanoliposomes were produced at different weight ratios of ferrous sulfate to the total formulation components (0.06, 0.035, 0.02, an…
The ARF GAPs ELMOD1 and ELMOD3 act at the Golgi and Cilia to Regulate Ciliogenesis and Ciliary Protein Traffic
2021
ABSTRACTELMODs are a family of three mammalian paralogs that display GTPase activating protein (GAP) activity towards a uniquely broad array of ADP-ribosylation factor (ARF) family GTPases that includes ARF-like (ARL) proteins. ELMODs are ubiquitously expressed in mammalian tissues, highly conserved across eukaryotes, and ancient in origin, being present in the last eukaryotic common ancestor. We described functions of ELMOD2 in immortalized mouse embryonic fibroblasts (MEFs) in the regulation of cell division, microtubules, ciliogenesis, and mitochondrial fusion. Here, using similar strategies with the paralogs ELMOD1 and ELMOD3, we identify novel functions and locations of these cell regu…
