O caso do Jornal de Notícias
A evolução do jornalismo abriu espaço para o surgimento de ramos específicos, espoletando o
interesse dos cidadãos por conteúdos personalizados. É neste ambiente que o jornalismo
desportivo ganhou forma e uma legião de adeptos. Os meios de comunicação ao acompanharem
a par e passo a realidade social, contribuíram de forma acérrima para o desenvolvimento desta
especialização jornalística, dado o protagonismo conferido.
O sucessivo destaque editorial é matéria de análise, uma vez que o Desporto envolve inúmeras
práticas, no entanto o realce parece estar sempre confinado a uma única modalidade: o
futebol. Aquele que é considerado o desporto rei aparenta assaltar as capas e os conteúdos
noticiosos desportivos, relegando as demais modalidades existentes para segundo plano. É
neste seguimento, que o presente estudo procura encontrar fundamentos para esta hegemonia
futebolística.
Será que os critérios de noticiabilidade aplicados variam de modalidade para modalidade? De
forma a encontrar resposta para a questão colocada, bem como para outras que se revelam
pertinentes, baseei-me na recolha e análise de dados, centrados nas capas e nas páginas da
secção de Desporto de um mês do Jornal de Notícias, complementando este estudo com a
realização de entrevistas, nomeadamente ao próprio protagonista, o editor, a quem cabe as
tomadas de decisão editoriais, assumindo-se, por isso, como o responsável pela divisão do
protagonismo desportivo. Após a análise a que me propus levar a cabo, mediante a aplicação
dos vários critérios noticiosos, o futebol sedimentou a posição líder dos destaques, assumindose claramente como o privilegiado. O desporto rei demonstra gozar de uma aplicação de
critérios mais amplos comparativamente com as restantes modalidades desportivas,
dependentes do calendário desportivo anual para se assumirem como matéria de notícia.The evolution of journalism opened space for the emergence of specific branches, triggering
the interest of citizens in personalized content. It is in this environment that Sports Journalism
gained form and a legion of followers. The media, by following the social reality step by step
with each other, have contributed decisively to the development of this journalistic
specialisation, due to the protagonism that has been conferred.
The successive editorial prominence is a matter of analysis, since that sport involves countless
practices, however the emphasis always seems to be confined to a single modality: Football.
The one that is regarded as the king sport seems to steal the covers and the sports news
content, relegating the other existing sports to second place. It is in this context that the
present study seeks to find grounds for this football hegemony.
Do the applied criteria of reportability vary from modality to modality? In order to find an
answer to the question raised, as well as to others that reveal to be pertinent, I based myself
on a collection and analysis of data, assigned to the covers and pages of the Sports section of
a single month of the Jornal de Notícias, complementing this study with interviews, namely to
the protagonist himself, the editor, who is responsible for the editorials decisions, assuming,
therefore, as the responsible for dividing the sports protagonism. Following the analysis that I
proposed to conduct, through the application of various news benchmarks, football
consolidated its leading position in terms of highlights, clearly assuming itself as the privileged
one. The king sport evidences to benefit from an application of wider criteria compared to the
other sports modalities, that are dependent on the annual sports calendar to be assumed as
news matter
Correlations between risk factors for prostate cancer: an epidemiological analysis
Objective: To establish correlations between risk factors for prostate cancer. Method: 155 Medical records of patients with prostate cancer were analyzed regarding the tumor characteristics and risk factors. Results: The patients on average were 70 years of age, incomplete grade school (70%), exposed to pesticides (68,56%), non-smokers (93,8%), and alcohol consumption (71,2%), patients with adenocarcinoma (98,71%) and metastases (12,90%). Positive correlations (0.001) were evidenced with occupational exposure (r= 0,588), use of medications (r= 0,569) and radiation exposure (r= 0.609). No correlations were observed for diet, smoking and alcoholism. Conclusion: The data show that for associations between genetic factors and occupational exposure, with emphasis to the mutagenicity and carcinogenicity
Chromosome 1p36 deletion syndrome: a report on 4 cases
Chromosome 1p36 deletion syndrome (MIM #607872) was first described in 1997 by Shapira et al. This condition is compatible with a monosomy of the 1p36 band in the distal region of the short arm of chromosome 1 and is the most common terminal deletion in humans, with an estimated prevalence of approximately 1 in 5,000 live births. This constitutional deletion is associated with mental retardation, developmental delay, seizures, hypotonia and heart defects. The syndrome is also characterized by several distinct dysmorphic features, including large anterior fontanels, microcephaly, brachycephaly, deep-set eyes, flat nose and nasal bridge, and pointed chin. The 1p36 band is not very clearly visible using classical cytogenetics, and it is therefore difficult to detect these deletions in banded karyotypes. Fluorescence in situ hybridization (FISH) and multiplex ligation-dependent probe amplification (MLPA) analysis have increasingly been used, in addition to classical cytogenetic analysis, in children with mental retardation in order to identify this chromosomal abnormality. The authors present four patients between 1 month and 14 years of age with apparently normal karyotypes. Using molecular cytogenetic techniques, all cases showed a “pure” 1p36 deletion: three were detected by FISH (CEB108/T7, located at 1p36.3, Vysis) and are “de novo”; the fourth was detected by MLPA (P036 and P070, MRC Holland) analysis, and its origin is still unknown. The phenotypes of these patients are described and compared with other cases having this syndrome, described in the literature. We also emphasize the importance of good clinical characterization in order to establish the best cytogenetic strategy to assure accurate diagnosis

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal
Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by
the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration
with more than 50 laboratories distributed nationwide.
Methods By applying recent phylodynamic models that allow integration of individual-based
travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal.
Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from
European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland),
which were consistent with the countries with the highest connectivity with Portugal.
Although most introductions were estimated to have occurred during early March 2020, it is
likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the
first cases were confirmed.
Conclusions Here we conclude that the earlier implementation of measures could have
minimized the number of introductions and subsequent virus expansion in Portugal. This
study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil
The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
Marginal microleakage in Bulk Fill resins
Abstract Introduction Despite advances and innovations in restorative dentistry, microleakage remains one of the main problems in this area. Objective To evaluate in vitro marginal microleakage of Bulk Fill resins in class II cavities, with cervical termination in the dentin. Material and method Cavities, standardized on the mesial and distal surfaces, were prepared in forty top molars and randomly assigned to four groups (n = 10), according to the resin used. G1 (control): Filtek Z350 (3M/ESPE); G2: Filtek Bulk Fill flow (3M/ESPE); G3: Surefill SDR (Dentsply); G4: X-tra (Voco). These were further subdivided into subgroups according to the strategy used to apply the adhesive (self-etch technique and conventional). After storage for 24 hours in an oven (37 °C), the samples were submitted to the thermocycling test (500 cycles: 5 °C/55 °C). They were later waterproofed, immersed in Basic Fuchsin (0.5%) and sectioned in the mesial-distal direction for evaluation using a stereo magnifying glass at 40X (Coleman) Scores from 0 to 3 were assigned according to the microinfiltration observed. The Mann-Whitney and Kruskal-Wallis tests, with a significance level of 5%, were used for statistical analysis. Result There was no statistically significant difference between the Bulk Fill resins when the total acid-etching technique was used. Only the Filtek Bulk fill flow resin presented statistically significant results when the application of the adhesive system strategy was considered, with worse results, in relation to other groups, when it the self-etching strategy was considered. Conclusion The degree of leakage of the bulk fill resins studied, in class II cavities, was not influenced by the method of application of the adhesive system (conventional or two-step self-etching bonding agent), except for the Filtek Bulk fill flow
