Etiologia da peri-implantite

A doença peri-implantar é um processo inflamatório nos tecidos à volta do(s) implante(s), que se pode dividir em duas fases. Inicia-se, sempre, por uma mucosite peri-implantar, que se não for tratada, pode evoluir para peri-implantite. Neste trabalho, visa-se compreender a etiologia da peri-implantite para que seja possível efetuar um diagnóstico correto e tomar decisões clínicas acertadas. Fatores de risco e a prevalência, também serão analisados. Para tal, efetuou-se pesquisa bibliográfica na base de dados eletrónica PubMed. A pesquisa foi restrita aos idiomas: Português, Inglês e Espanhol e apenas estudos realizados em humanos foram considerados. A etiologia da peri-implantite é multifatorial, bastante complexa e controversa. A presença de placa bacteriana é a principal causa das doenças peri-implantares. Outros fatores são considerados de risco mas não são, por si só, causadores de peri-implantite. Mais estudos são necessários para aprofundar este tema e haver maior consenso entre os autores.Peri-implant disease is an inflammatory process that occurs in the tissues around the implant(s). This process can be divided into two stages: the first is the peri-implant mucositis, which, if untreated, progresses to the second stage: peri-implantitis. This study aims to understand the etiology of peri-implantitis in order to perform a better diagnosis and following correct clinical decisions. Risk factos and prevalence will also be analyzed. For this purpose, it was made a bibliographic search in the PubMed database. The research was done in the languages of: Portuguese, English and Spanish. Only human studies were considered. The etiology of peri-implantitis is multifactorial, complex and controversial. The presence of plaque is the main cause of peri-implant diseases, although there are other factos that are associated with increased risk. Further studies are needed to better understand this subject and to seek consensus among authors

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.

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. MAMMALS IN PORTUGAL is a publicly available data set compiling unpublished georeferenced occurrence records of 92 terrestrial, volant, and marine mammals in mainland Portugal and archipelagos of the Azores and Madeira that includes 105,026 data entries between 1873 and 2021 (72% of the data occurring in 2000 and 2021). The methods used to collect the data were: live observations/captures (43%), sign surveys (35%), camera trapping (16%), bioacoustics surveys (4%) and radiotracking, and inquiries that represent less than 1% of the records. The data set includes 13 types of records: (1) burrows | soil mounds | tunnel, (2) capture, (3) colony, (4) dead animal | hair | skulls | jaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8), observation in shelters, (9) photo trapping | video, (10) predators diet | pellets | pine cones/nuts, (11) scat | track | ditch, (12) telemetry and (13) vocalization | echolocation. The spatial uncertainty of most records ranges between 0 and 100 m (76%). Rodentia (n =31,573) has the highest number of records followed by Chiroptera (n = 18,857), Carnivora (n = 18,594), Lagomorpha (n = 17,496), Cetartiodactyla (n = 11,568) and Eulipotyphla (n = 7008).

Objetos de ensino e o patrimônio cultural de ciência e tecnologia no Brasil e em Portugal: contribuições sobre levantamentos e inventários como instrumentos de preservação em escolas de ensino médio

RESUMO O trabalho faz reflexões sobre o patrimônio cultural no âmbito das escolas de ensino médio, analisando algumas iniciativas de levantamentos e de valoração dos objetos de ensino enquanto bens culturais. Para tanto, buscamos traçar um perfil analítico de projetos de inventário desse patrimônio cultural no Brasil e em Portugal. A partir das lentes da ciência e tecnologia, utilizou-se a revisão bibliográfica e os contatos com as instituições como metodologia para comparar o estado de pesquisas de inventário sobre estes objetos. Observou-se que as iniciativas aqui estudadas são assimétricas, necessitando ser padronizadas e aprofundadas de forma a alcançar as diferentes modalidades de ensino e, consequentemente, obter resultados mais consistentes e efetivos do ponto de vista da preservação. No entanto, percebe-se que existe um movimento crescente de identificação e preservação desses artefatos nos dois países

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

A dataset of acoustic measurements from soundscapes collected worldwide during the COVID-19 pandemic

International audiencePolitical responses to the COVID-19 pandemic led to changes in city soundscapes around the globe. From March to October 2020, a consortium of 261 contributors from 35 countries brought together by the Silent Cities project built a unique soundscape recordings collection to report on local acoustic changes in urban areas. We present this collection here, along with metadata including observational descriptions of the local areas from the contributors, open-source environmental data, open-source confinement levels and calculation of acoustic descriptors. We performed a technical validation of the dataset using statistical models run on a subset of manually annotated soundscapes. Results confirmed the large-scale usability of ecoacoustic indices and automatic sound event recognition in the Silent Cities soundscape collection. We expect this dataset to be useful for research in the multidisciplinary field of environmental sciences
