Élites locales y sus bases sociales en la América Portuguesa : una tentativa de aplicación de las análisis de redes sociales
As análises de redes sociais (social network analysis) foram desenvolvidas para o estudo das relações existentes entre os agentes, de forma a demonstrar com maior clareza as teias que se formam nas interações humanas. Tal metodologia de análise dá especial atenção às conexões sociais, sejam estas de parentesco, amizade, afinidade, ou quaisquer outros tipos indicados pelo pesquisador que, além de definir a qualidade das relações, aponta sua intensidade, baseado em critérios pré-estabelecidos. Para testar esta metodologia, vamos lançar mão de um caso particular, uma parcela da elite da Capitania do Rio Grande de São Pedro, sul da América Portuguesa, em finais do século XVIII. Neste trabalho, identificamos a existência de um “bando” na fronteira sul do Estado do Brasil, com forte atuação no contrabando. A metodologia empregada e o gráfico gerado foram relevantes, não apenas para a testar algumas hipóteses, mas também para a identificação de novos problemas.Los análisis de redes sociales (social network analysis) fueron desarrollados para el estudio de las relaciones existentes entre los agentes, para demostrar con claridad los vínculos que se forman en las interacciones humanas.

Alternative ways of data visualization in history : some research notes
O objetivo deste artigo é apresentar algumas inquietações teóricas e metodológicas sobre a forma como os historiadores representam o conhecimento histórico, dando especial atenção ao uso de gráficos interativos, mapas dinâmicos e animações. Se o objeto do conhecimento histórico tem diferentes movimentos, distintas intensidades, por que seria o papel impresso o principal (senão único) veículo de divulgação deste conhecimento? Diante de objeto tão escorregadio e de difícil apreensão, os historiadores optaram, desde o século XIX até o presente, por narrar (através da escrita) as dinâmicas sociais, sem preocupação com formas alternativas de representação. Muito recentemente, o fenômeno das mídias digitais e da internet trouxe inspiração para os profissionais do tempo social, permitindo algumas experiências inovadoras. É sobre algumas destas experiências que o texto tratará.The paper presents some theoretical and methodological inquiries about the ways in which historians produced historical scholarship, emphasizing the use of interactive graphs, dynamic maps and animations. If the object of historical research has different flows and diverse intensities, why would be the written paper the main (if not the only) mean of publishing historical knowledge? Historians have chosen, since the nineteenth century, to narrate through writing the social dynamics of the past, barely exploring alternatives ways of representation. Recently, new digital platforms have been inspiring historians and social scientists interested in the historical time to produce some groundbreaking experiments. These experiments, thus, are the object of this paper
Dietary supplementation with chestnut (Castanea sativa) reduces abdominal adiposity in FVB/n mice: a preliminary study
The production of chestnut (Castanea sativa Miller) is mostly concentrated in Europe.
Chestnut is recognized by its high content of antioxidants and phytosterols. This work aimed to
evaluate the e ects of dietary chestnut consumption over physiological variables of FVB/n mice.
Eighteen FVB/n male 7-month-old mice were randomly divided into three experimental groups
(n = 6): 1 (control group) fed a standard diet; 2 fed a diet supplemented with 0.55% (w/w) chestnut;
and 3 supplemented with 1.1% (w/w) chestnut. Body weight, water, and food intake were recorded
weekly. Following 35 days of supplementation, the mice were sacrificed for the collection of biological
samples. Chestnut supplementation at 1.1% reduced abdominal adipose tissue. Lower serum
cholesterol was also observed in animals supplemented with chestnut. There were no significant di erences concerning the incidence of histological lesions nor in biochemical markers of hepatic
damage and oxidative stress. These results suggest that chestnut supplementation may contribute to
regulate adipose tissue deposition.This work is supported by National Funds by FCT - Portuguese Foundation for Science and Technology,

Prototype of an affordable pressure-controlled emergency mechanical ventilator for COVID-19
We present a viable prototype of a simple mechanical ventilator intended as a
last resort to ventilate COVID-19 patients. The prototype implements the
pressure-controlled continuous mandatory ventilation mode (PC-CMV) with
settable breathing rates, inspiration/expiration time ratios and FiO2
modulation. Although safe, the design aims to minimize the use of technical
components and those used are common in industry, so its construction may be
possible in times of logistical shortage or disruption or in areas with reduced
access to technical materials and at a moderate cost, affordable to lower
income countries. Most of the device can be manufactured by modest technical
means and construction plans are provided.Comment: This version differs from version 2 in that it includes toxicological
and bio-safety tests and updated electronic
Toxicological and anti-tumor effects of a linden extract (Tilia platyphyllos Scop.) in a HPV16-transgenic mouse model
Tilia platyphyllos Scop. is a popular broad-leaved tree, native to Central and Southern Europe. Hydroethanolic extracts rich in phenolic compounds obtained from T. platyphyllos Scop. have shown in vitro antioxidant, anti-inflammatory and antitumor properties. The aim of this work was to evaluate the therapeutic properties of a hydroethanolic extract obtained from T. platyphyllos in HPV16-transgenic mice. The animals were divided into eight groups according to their sex and phenotype. Four groups of female: HPV+ exposed to linden (HPV linden; n = 6), HPV+ (HPV water; n = 4), HPV- exposed to linden (WT linden; n = 5) and HPV- (WT water; n = 4) and four groups of male: HPV+ exposed to linden (HPV linden; n = 5), HPV+ (HPV water; n = 5), HPV- exposed to linden (WT linden; n = 5) and HPV- (WT water; n = 7). The linden (Tilia platyphyllos Scop.) extract was orally administered at a dose of 4.5 mg/10 mL per animal (dissolved in water) and changed daily for 33 days. The hydroethanolic extract of T. platyphyllos consisted of protocatechuic acid and (-)-epicatechin as the most abundant phenolic acid and flavonoid, respectively, and was found to be stable during the studied period. In two male groups a significant positive weight gain was observed but without association with the linden extract. Histological, biochemical, and oxidative stress analyses for the evaluation of kidney and liver damage support the hypothesis that the linden extract is safe and well-tolerated under the present experimental conditions. Skin histopathology does not demonstrate the chemopreventive effect of the linden extract against HPV16-induced lesions. The linden extract has revealed a favourable toxicological profile; however, additional studies are required to determine the chemopreventive potential of the linden extract.

Does the white coat influence satisfaction, trust and empathy in the doctor-patient relationship in the General and Family Medicine consultation? Interventional study
Objectives To understand the influence of the white coat on
patient satisfaction, opinions about medical clothing, perception
about confidence, empathy and medical knowledge and the
satisfaction and comfort level of physicians in consultation.
Setting An interventional study was conducted with a
representative sample of the population attending primary care
in central Portugal.
Participants The sample was composed by 286 patients
divided into two groups exposed or not to a doctor wearing a
white coat. The first and last patients in consultation every day
for 10 consecutive days were included.
Interventions Every other day the volunteer physicians
consulted with or without the use of a white coat. At the end
of the consultation, a questionnaire was distributed to the
patient with simple questions with a Likert scale response, the
Portuguese version of the ‘Trust in physician’ scale and the
Jefferson Scale of Patient Perceptions of Physician Empathy
- Portuguese Version (JSPPPE-VP
scale). A questionnaire was
also distributed to the physician.
Outcomes Planned and measured primary outcomes were
patient satisfaction, trust and perception about empathy and
secondary outcomes were opinion about medical clothing,
satisfaction and comfort level of physicians in consultation.
Results The sample was homogeneous in terms of
sociodemographic variables. There were no statistically
significant differences between the groups in terms of
satisfaction, trust, empathy and knowledge perceived by the
patients. There were differences in the opinion of the patients
about the white coat, and when the physician was wearing
the white coat this group of patients tended to think that this
was the only acceptable attire for the physician (p<0.001).
But when the family physician was in consultation without
the white coat, this group of patients tended to agree that
communication was easier (p=0.001).
Conclusions There was no significant impact of the white
coat in patient satisfaction, empathy and confidence in the
family physician.

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.

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.
