Ēšanas traucējumu pazīmes, attieksme pret lieko svaru un ķermeņa tēla uztvere veģetāriešiem

2017

Maģistra darba mērķis ir noteikt kādas ir saistības un atšķirības ēšanas traucējumu pazīmēm attieksmē pret lieko svaru un ķermeņa tēla uztveri gaļas ēdājiem un veģetāriešiem. Pētījumā piedalījās 205 respondenti vecumā no 18-76 gadiem. Respondenti sastāv no divām izlasēm. Pirmājā ietilpst cilvēki, kuri ir gaļas ēdāji, bet otrā, cilvēki, kuri ir veģetārieši. Pētījuma izlases veidoja 127 gaļas ēdāji un 78 veģetārieši. 85 no dalībniekiem ir vīrieši un 120 ir sievietes. Pētījumā ir iekļautas trīs aptaujas. Tika izmantota aptauja par attieksmi pret ēšanu, lai mērītu ēšanas traucējumu pazīmes. Lai mērītu rezultātus attieksmē pret lieko svaru, tika izmantota anti-tukluma attieksmju, bet ķermeņa tēl…

An arthritogenic alphavirus uses the α1β1 integrin collagen receptor

2005

Ross River (RR) virus is an alphavirus endemic to Australia and New Guinea and is the aetiological agent of epidemic polyarthritis or RR virus disease. Here we provide evidence that RR virus uses the collagen-binding alpha1beta1 integrin as a cellular receptor. Infection could be inhibited by collagen IV and antibodies specific for the beta1 and alpha1 integrin proteins, and fibroblasts from alpha1-integrin-/- mice were less efficiently infected than wild-type fibroblasts. Soluble alpha1beta1 integrin bound immobilized RR virus, and peptides representing the alpha1beta1 integrin binding-site on collagen IV inhibited virus binding to cells. We speculate that two highly conserved regions with…

α-Conotoxins EpI and AuIB switch subtype selectivity and activity in native versus recombinant nicotinic acetylcholine receptors

2003

The Xenopus laevis oocyte expression system was used to determine the activities of alpha-conotoxins EpI and the ribbon isomer of AuIB, on defined nicotinic acetylcholine receptors (nAChRs). In contrast to previous findings on intracardiac ganglion neurones, alpha-EpI showed no significant activity on oocyte-expressed alpha3beta4 and alpha3beta2 nAChRs but blocked the alpha7 nAChR with an IC50 value of 30 nM. A similar IC50 value (103 nM) was obtained on the alpha7/5HT3 chimeric receptor stably expressed in mammalian cells. Ribbon AuIB maintained its selectivity on oocyte-expressed alpha3beta4 receptors but unlike in native cells, where it was 10-fold more potent than native alpha-AuIB, had…

I MONUMENTI AI SOVRANI SPAGNOLI IN SICILIA NELLA SECONDA METÀ DEL SEICENTO: IL CASO DI FILIPPO IV A PALERMO E DI CARLO II A MESSINA

2018

I MONUMENTI AI SOVRANI SPAGNOLI IN SICILIA NELLA SECONDA METÀ DEL SEICENTO: IL CASO DI FILIPPO IV A PALERMO E DI CARLO II A MESSINA-Nella seconda metà del Settecento vennero eretti in Sicilia due grandiosi monumenti per celebrare gli ultimi re di Spagna della Casa d'Asburgo: il “teatro” di Filippo IV nel piano del palazzo Reale di Palermo (dal 1661) e il gruppo scultoreo con la statua equestre di Carlo II (dal 1680) nella piazza della cattedrale di Messina. I due monumenti rendevano omaggio in Sicilia, nei luoghi eletti simbolo del potere della corona spagnola, i trionfi di sovrani ancora in vita e secondo parametri compositivi articolati e meritevoli di attenzione. L’adozione di un reperto…
