Insomnia: prevalence and associated factors

Nowadays sleep disorders are very common and affect most of the population, the most common may be insomnia. Insomnia is defined as the difficulty of initiating or maintaining sleep it, may also be reflected in an early wake up and by the presence of a non-restful sleep and it is associated with impairment in social and occupational functioning of the individual. Knowing the prevalence and the associated factors of insomnia. This is a cross-sectional epidemiological study. The population is constituted by 205 individuals of both sexes, aged over 18, who were in public places of a city in the north of the country. We applied a questionnaire to all the people who went through these places between 9 am to 7 pm. Insomnia was evaluated using the DSM-IV (Diagnosis and Statistical Manual of Mental Disorders). We use the Chi-square to study the relation between the independent variables with variable insomnia, adopting a confidence interval of 95%. The prevalence of insomnia was 46.8%. Who suffers more from insomnia are: women in menopause (64.1%), elder people (66.7%) and those with four or fewer years of education (73.9%). There was no significant statistical relationship between the prevalence of insomnia and sex or residence. The causes of insomnia are: concern (48.6%), noise (31.8%) and disease (8.4%). The drugs most consumed by insomniacs are benzodiazepines (79.2%). In this study insomnia affects about half of participants. The presence of insomnia seems to be related with the age increasing, low education and menopausal status in female

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%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

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.

Downregulation of Sirtuin 1 Does Not Account for the Impaired Long-Term Potentiation in the Prefrontal Cortex of Female APPswe/PS1dE9 Mice Modelling Alzheimer’s Disease

Alzheimer’s disease (AD), which predominantly affects women, involves at its onset a metabolic deregulation associated with a synaptic failure. Here, we performed a behavioral, neurophysiological and neurochemical characterization of 9-month-old female APPswe/PS1dE9 (APP/PS1) mice as a model of early AD. These animals showed learning and memory deficits in the Morris water maze, increased thigmotaxis and anxiety-like behavior and showed signs of fear generalization. Long-term potentiation (LTP) was decreased in the prefrontal cortex (PFC), but not in the CA1 hippocampus or amygdala. This was associated with a decreased density of sirtuin-1 in cerebrocortical synaptosomes and a decreased density of sirtuin-1 and sestrin-2 in total cerebrocortical extracts, without alterations of sirtuin-3 levels or of synaptic markers (syntaxin, synaptophysin, SNAP25, PSD95). However, activation of sirtuin-1 did not affect or recover PFC-LTP deficit in APP/PS1 female mice; instead, inhibition of sirtuin-1 increased PFC-LTP magnitude. It is concluded that mood and memory dysfunction in 9-month-old female APP/PS1 mice is associated with a parallel decrease in synaptic plasticity and in synaptic sirtuin-1 levels in the prefrontal cortex, although sirtiun1 activation failed to restore abnormal cortical plasticity

Educomunicação: caminhos entre a pesquisa e a formação, no II Congresso Internacional de Comunicação e Educação

A herança cultural representada pelos papers propostos e aprovados pela comissão científica do II Congresso Internacional de Comunicação e Educação e VIII Encontro Brasileiro de Educomunicação, está na publicação em quatro diferentes e-books, disponibilizados na plataforma de publicações do site da ABPEducom (www.abpeducom.com.br).  O presente volume – o segundo a ser disponibilizado ao público – volta-se, mais especificamente, a dois eixos temáticos, relacionados, respectivamente, à pesquisa e à formação no campo da Educomunicação. Pesquisa e formação são dois eixos fundamentais para garantir o que se define como coerência epistemológica entre teoria e prática. E é sobre esta perspectiva que os artigos reunidos neste e-book devem ser recebidos e confrontados. Falamos inicialmente sobre uma coerência epistemológica no interior do próprio produto analisado. Sinalizamos com isto que os autores podem ter desenvolvido abordagens não necessariamente alinhadas aos referenciais da Educomunicação na perspectiva defendida, por exemplo, pelo NCE-USP. O fato não desautoriza o texto, ao contrário: se foram incluídos no livro é porque trabalham com pensamentos e ações com os quais a Educomunicação pode e deve estar dialogando, especialmente nos âmbito do uso das TIC e na implementação de programas de educação mediática e informacional

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
