Empréstimos com arte: criação de valor partilhado multidimensional entre público(s) e privado(s)
Este projeto de Mestrado tem como finalidade criar uma entidade que promova e execute
exposições temporárias em Museus Públicos do país com obras provenientes de coleções privadas,
contribuindo assim para a diversificação de fontes de financiamento e sustentabilidade dos mesmos.
Este projeto insere-se, assim, numa discussão mais vasta que se debruça sobre a relação
entre a sociedade e as empresas e a possibilidade de harmonização dos seus objetivos. Neste
projeto, partir-se-á de um quadro teórico norteado pela teoria de criação de valor partilhado para um
Modelo de negócio que permita articular entre si quatro quadrantes que são parte integrante do
projeto: os públicos visitantes das exposições, os privados colecionadores de obras, o setor público,
no qual se inserem os museus de arte públicos, e o setor privado no seu todo.
Este projeto tem, assim, a finalidade de promover uma forma mais conscienciosa de olhar
para o investimento em arte, apresentando os múltiplos benefícios para os quadrantes acima
mencionados e uma visão holística da criação de valor, ou seja, uma visão que não contempla
apenas as métricas monetárias, mas que apresenta e inclui outros componentes de valor tais como o
social e o cultural.The following Master's degree project aims at creating an entity that is able to promote and run
temporary exhibitions at Portuguese Public Museums, exhibiting works from private collections,
thus contributing to the diversification of funding sources and to the sustainability of those
museums. This project departs from is part of like a more problematic discussion that takes into
account the discussions between company / firm, and its confluence of objectives This is based on a
theoretical framework guided by shared value creation theory for a Business model that allowed
coordinate among themselves four quadrants that are directly related with the project: visitors to the
public exhibitions, private collectors of works, the public sector in which they operate public art
museums, and the private sector as a whole.
This project has a purpose of promoting a more conscientious way of looking at investing in
art thus presenting multiple benefits of various orders and a holistic view of value creation, not only
take into account monetary metrics, but also has several components value components such as
social and cultura
Tumor-associated and immunochemotherapy-dependent long-term alterations of the peripheral blood NK cell compartment in DLBCL patients
Natural Killer (NK) cells are a key component of tumor immunosurveillance and thus play an important role in rituximab-dependent killing of lymphoma cells via an antibody-dependent cellular cytotoxicity (ADCC) mechanism. We evaluated the phenotypic and functional assets of peripheral blood NK cell subsets in 32 newly-diagnosed diffuse large B-cell lymphoma (DLBCL) patients and in 27 healthy controls. We further monitored long-term modifications of patient NK cells for up to 12 months after rituximab-based immunochemotherapy. At diagnosis, patients showed a higher percentage of CD56dim and CD16C NK cells, and a higher frequency of GrzBC cells in CD56dim, CD56bright, and CD16C NK cell subsets than healthy controls. Conversely, DLBCL NK cell killing and interferon g (IFNg) production capability were comparable to those derived from healthy subjects. Notably, NK cells from refractory/relapsed patients exhibited a lower “natural” cytotoxicity. A marked and prolonged therapy-induced reduction of both “natural” and CD16- dependent NK cytotoxic activities was accompanied by the down-modulation of CD16 and NKG2D activating receptors, particularly in the CD56dim subset. However, reduced NK cell killing was not associated with defective lytic granule content or IFNg production capability. This study firstly describes tumor-associated and therapy-induced alterations of the systemic NK cell compartment in DLBCL patients. As these alterations may negatively impact rituximab-based therapy efficacy, our work may provide useful information for improving immunochemotherapeutic strategies
Glucocorticoids and Antivirals for HBV Reactivation in Onco-Hematologic Patients.
Patients with inactive or occult hepatitis B virus infection and onco-hematological malignancies are at risk of hepatitis flare, hepatic failure and death due to chemotherapy-mediated reactivation. Nucleot(s)ide analogues can reduce reactivation risks and/or hepatitis. However, immuno-mediated phenomena combine to determine liver damage and clinical outcome. We describe in this report two patients with onco-hematological malignancies and hepatitis B reactivation after chemotherapy in whom glucocorticoids were added to nucleot(s)ide. Antiviral therapy was effective on replication, while glucocorticoids managed hyperergic response. One patient without underlying liver disease survived, while the second died and the autopsy demonstrated cirrhosis undetected before death. This clinical trial suggests that in patients with onco-hematological malignancies and altered liver function tests in spite of effective antiviral response, glucocorticoids could control the effects of immune response. However prognosis and survival are related to the underlying liver status
MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal
Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%).

Mammals in Portugal: a data set of terrestrial, volant, and marine mammal occurrences in Portugal
Mammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information on their distribution is crucial to delineate and support conservation actions.

Studio multicentrico su un preparato topico ad azione linfodrenante nel trattamento dell’ulcera flebostatica degli arti inferiori
Le ulcere flebostatiche degli arti inferiori rappresentano una tipica complicanza dell’insufficienza venosa cronica e il loro trattamento è tuttora controverso. Infatti le comuni terapie non sono ancora standardizzate e non mostrano una totale efficacia.
Tra il 2005 e il 2007 è stato condotto presso il Dipartimento di Chirurgia Plastica e Ricostruttiva della “Sapienza”, Università di Roma e presso il Dipartimento di Chirurgia Plastica e Ricostruttiva dell’Università di Perugina, uno studio multicentrico volto a valutare l’efficacia della crema linfodrenante Idrastin® in pazienti affetti da ulcere flebostatiche degli arti inferiori.
Lo studio è stato condotto su 80 pazienti, suddivisi in 2 gruppi omogenei di 40 pazienti: il gruppo A è stato trattato unicamente con terapia elastocompressiva, il gruppo B con terapia elastocompressiva associata all’utilizzo di Idrastin®. L’analisi multicentrica ha preso in considerazione parametri quali il dolore locale, la flogosi perilesionale, la comparsa di tessuto di granulazione, il trofismo dei tessuti perilesionali e il tempo di guarigione. I risultati evidenziati nel gruppo B sono: riduzione del dolore locale fino alla scomparsa in 72 ore; decremento dell’infiammazione con scomparsa in una settimana; crescita di tessuto di granulazione in una settimana; guarigione della lesione in 4 settimane.
Questi risultati confermano la significatività statistica delle variabili prese in considerazione. Riteniamo che, relativamente ai composti contenuti nell’Idrastin®, i fitoestratti di luppolo e di edera hanno contribuito all’effetto analgesico; i fitoestratti di Aesculus hippocastanum, di Vitis vinifera e di Ruscus aculeatus hanno mostrato attività antiflogistica; l’allantoina, la Centella asiatica l’acido ialuronico hanno coadiuvato la guarigione delle ulcere. Idrastin® fornisce un efficace supporto al trattamento delle ulcere flebostatiche garantendo un processo di guarigione più veloce e più efficace rispetto alle lesioni trattate con la sola elastocompressione
Hemipelvectomy and reconstruction in a patient with advanced Marjolin's ulcer: a case report.
Patients with squamous cell carcinoma of the lower limb may exhibit locally advanced or metastatic disease. Surgical resection to control the primary tumor is often extensive.The case of a 51-year-old man with squamous cell carcinoma on Marjolin?€™s ulcer affected, rapidly growing, and involving soft and bone tissues is described. Treatment required performing a hemipelvectomy. Immediate reconstruction was chosen as surgical procedure planning the harvest of 4 superficial muscles and 1 deep muscle of the abdomen to protect the pelvic content and to eliminate the dead spaces.The chosen technique minimized postoperative complications, and at 7 years follow-up, the patient is disease free
