Coronavirus disease 2019 (CoViD-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Among many symptoms, cough, fever and tiredness are the most common. People over 60 years old and with associated comorbidities are most likely to develop a worsening health condition. This paper proposes a non-integer order model to describe the dynamics of CoViD-19 in a standard population. The model incorporates the reinfection rate in the individuals recovered from the disease. Numerical simulations are performed for different values of the order of the fractional derivative and of reinfection rate. The results are discussed from a biological point of view.

Radiomics is an emerging area, which presents a large set of computational methods and techniques to extract quantitative characteristics from magnetic resonance images. In the feature extraction stage, its outputs must be well defined and carefully evaluated, to provide imaging diagnostics, prognoses and responses to treatment therapies. In this study, we present the extraction of quantitative characteristics from magnetic resonance images in low-grade gliomas using the Pyradiomics library and, using a multilayer perceptron neural network, we will show the prediction of the deletion of the 1p / 19q chromosomes in these gliomas. Several studies show that 1p / 19q chromosomal codelection is a positive prognostic factor in low-grade gliomas, as they are more sensitive to chemotherapy. Due to the large number of extracted characteristics, it was necessary to use a dimensionality reduction technique, the analysis principal components, which proved to be efficient in this study. After training and testing the characteristics performed by the multilayer perceptron neural network, the results showed to be very promising in detecting the deletion status of chromosomes 1p / 19q, mainly taking into account the possibility of avoiding surgical biopsies for this diagnosis., in Portuguese, Submitted to the XXVII Brazilian Congress of Biomedical Engineering

Rocha leg.; DZUP LEP-017, slide DZUP DID3.83. Description Colonies were found on exposed granitic substrate around 8 m deep. Brazilian specimens form black colonies in situ (Fig. 4 A���B) that when fixed turn whitish brown. Colonies are 2.5���6.0 cm wide and 2���4 mm thick. The tunic is firm, smooth and has no encrustations. Spicules are star-shaped, usually 35 ��m in diameter; however, the larger ones can reach 70 ��m in diameter. The spicules are uniformly distributed in low density in the tunic, with 8���10, usually conical rays in cross section. Between the conical rays there are granulated areas that resemble very short truncated rays (Fig. 4C). Zooids are ~ 1.2 mm long, with a 0.5 mm long thorax and 0.7 mm long abdomen. The thorax has 7���8 longitudinal muscle fibers on each side (Fig. 4D). The oral siphon is 0.25 mm long, tubular and with six short, rounded lobes along the margin. In some zooids the oral siphon is difficult to see, appearing as though it has no lobes. The atrial siphon is tubular and arises from the base of the thorax, with many circular muscle fibers (19���20) along its length. The siphon opens at the level of the fourth row of stigmata, usually downward oriented. In some zooids, the atrial and oral siphons are about the same length. The thoracic organ is circular, not salient, usually less than or the same size as the stigmata and is at the level of the third (sometimes between the third and fourth) row of stigmata. The pharynx has 12���13 stigmata on each side, in the first three rows, and 10���12 in the last row (Fig. 4E). The abdomen is horizontal, the esophagus short and narrow. The stomach is globular and is not overlapped by the intestinal loop. The testis has four, rarely five, follicles, overlain by six tightly coiled turns of the sperm duct. One specimen (DZUP DID-171, from Bahia) had a testis with four follicles and only four turns of the sperm duct. Larvae were only found in specimens from Bahia in August. They were immature and so some structures were not visible. The larval trunk was 0.65���0.75 mm long and the pharynx had 9���10 stigmata per half row. Remarks The type location for L. torosus is Guadalupe (Monniot 1983), and here we report it for the first time in the southern Atlantic. In our samples, the colonies were thinner, and spicules were not distributed in the same way as in Guadalupe (restricted to the level of the abdomens), nor did they have papillae of spicules on the surface as in Monniot (1983). Otherwise, the color of the colony, spicule shape, number of testicular follicles, turns of the sperm duct and larval size all agree with the original description of the species.

Description Colonies were found exposed on granitic substrate between 8 and 15 m. They have an orange and white marbled appearance, and colony shape follows that of the substrate (Fig. 1A). Colonies can be 2���5 cm in diameter and 1���2 mm thick. Color in fixed specimens becomes grayish. Common cloacal apertures are wide, white with conical projections with many spicules along the margin (Fig. 1B). The tunic is cartilaginous with a smooth surface. Spicules are 20���30 ��m in diameter, uniformly, but not densely, distributed throughout the tunic. Spicules are star-like with 6 conical rays in cross section and, at the base, the rays are separated from one another by a matrix covered by small, rounded projections (Fig. 1C). Zooids are about 1.6 mm long, with the thorax twice the length of the abdomen. The oral siphon is tubular, 0.44 mm long, with six short and rounded lobes, sometimes not easily visible. On each side of the thorax there are eight muscular fibers that extend from the oral siphon to just anterior to the rectal esophageal peduncle. The atrial siphon is long and oriented downward (Fig. 1D). Occasionally the atrial opening appears short, probably due to the position of the zooid within the colony. Both siphons have conspicuous circular musculature. The pharynx has 10 stigmata per row on each side, except the last row, which has fewer stigmata (about 8���9). Stigmata are narrowly fusiform and slightly wider at the center. The thoracic organ is round, not raised, normally smaller than the size of the fold and located at the level of the fourth row of stigmata, almost in the middle of the thorax. The thoracic organ is often full of spicules. The abdomen is vertical, with a short and narrow esophagus. The stomach is large, elongate, and it is not overlapped by the intestinal loop (Fig. 1E). The testis has six rounded follicles. The sperm duct is spiral, with 4���6 counter-clockwise turns. The larval trunk is ovoid and ~ 0.7 mm in length. The tail curves �� of the way around the trunk. Three adhesive papillae are equally spaced with short, wide peduncles. Two pairs of large ectodermal ampullae are centrally located, and there is also one single dorsal and ventral ampullae, both smaller, for a total of six ampullae. The sensorial vesicle is posterior and the statocyte either anterior or ventral to the ocellus. Mature larvae have four rows of stigmata in the pharynx, with 10 stigmata in the first three rows and nine stigmata in the last. No pigment or ectodermal vesicles are present. Remarks Leptoclinides coronatus sp. nov. is very distinctive in comparison with the other congeners found in coastal Brazil. Leptoclinides crocotulus and L. latus are orange, but uniformly so and without swaths of white. Leptoclinides crocotulus is also different by the different shape and smaller (12 ��m) size of spicules, the different size and shape of the siphons, smaller lateral thoracic organ and three testicular follicles with two or three turns of the sperm duct (Paiva et al. 2015). It is also different from L. latus, which has a globular-type spicule, an atrial languet and fewer turns of the sperm duct. The Australian L. imperfectus (Kott, 1962) is marbled with orange and gray on a white background, but differs more clearly from L. coronatus sp. nov. in having papillae on the surface of the colony, a very long esophago-rectal peduncle, 6���8 testicular follicles and seven turns of the sperm duct and slightly smaller larvae (trunk ~ 0.6 mm long) with four pairs of ectodermal ampullae (Kott 2001). Also marbled, L. marmoreus Brewin, 1956 differs in having a smooth-margin cloaca and nine turns of the sperm duct (Brewin 1956), while L. marmoratum (Sluiter, 1909) is not orange, but rather gray or dark blue, has longer (3 mm) zooids and spicules in a narrow layer under the bladder cells, in addition to small groups of spicules scattered around the tunic (Sluiter 1909; Millar 1975).

Description Colonies in situ are orangish or salmon in color, with a variation of darker or lighter forms (Fig. 2 A���B), becoming white after fixation. Colonies are encrusting, with an irregular or somewhat oval outline, 3���5 cm wide and 2���4 mm thick and are more often found on the underside of rocks. Common cloacal apertures are large and abundant, round with a smooth border that when not well relaxed is somewhat wavy. The tunic is firm and easily broken due to abundant spicules that tend to be absent in the middle and base of the colony. In fixed colonies, the surface appears wrinkled and the oral siphons tend to become more salient. Spicules are globular, 15���30 ��m in diameter, with cylindrical, relatively short, blunt, irregularly pointed rays (numbering about 14 in cross section, Fig. 2C). Zooids, about 0.8���1.2 mm in length, have equally long thorax and abdomen. The oral siphon is short, tubular, with six rounded lobes around the margin. The atrial siphon is small, circular and smooth, in the middle of the thorax, between the second and third rows of stigmata. Some zooids have a bifurcate, wide, muscular, dorsal languet. The pharynx has 14 stigmata on each side of the first row and 13 stigmata in the remaining rows. There are six to eight muscle fibers in each side of the thorax. The thoracic organ is small, circular and between the second and third rows of the stigmata (Fig. 2D). The abdomen is vertical. The esophagus is short and narrow. The stomach is globular and is not overlapped by the intestinal loop. The testis has 3���4 small, oval follicles surrounded by two and a half or three, widely separated, turns of the sperm duct (Fig. 2E). Oocytes, present in the zooids of specimens DZUP DID-185 (Bahia) and DZUP LEP-014 (Esp��rito Santo), are 0.20���0.33 mm in diameter. Larvae are oval-shaped, with a trunk 0.70���0.85 mm in length. Larvae have three adhesive papillae in a row, with long, slender, equally spaced peduncles, and eight pairs of elongated, ectodermal ampullae (Fig. 2F). The tail curves around �� of the trunk. Larvae were found in specimens collected in November in Santa Catarina and in January to March (in immature state) in Esp��rito Santo. Remarks Leptoclinides latus was first reported in the Caribbean in Guadalupe (Monniot 1983). In Brazil, it was first found at the island Arvoredo, in the state of Santa Catarina (Rocha et al. 2005). Today, the species is known to have a much wider distribution in Brazil, from Bahia to Santa Catarina, and is the most common Brazilian species in the genus Leptoclinides. A few specimens had singular variations in characters when compared to most others. For example, the specimen from Bahia (DZUP DID-185) had a more open aperture and a longer rather than globular stomach, than is usually seen in most zooids. The colony collected in Cabo Frio (DZUP LEP-011) had five testicular follicles and the sperm duct with two turns only. Despite the variability described above, the remaining characters, including colony color, spicule size and shape, bifurcated atrial languet (where observed), and testis and larval shape and size, together clearly identify this species.

Leptoclinides lotufoi sp. nov. urn:lsid:zoobank.org:act: 31D0C00F-2263-4826-8CEC-9782A1704D49 Fig. 3 Etymology The name of this species is in homage to Dr Tito Lotufo for his studies in ascidian diversity in northeastern Brazil. He collected this material and lent it to us for this study. Material examined Holotype BRAZIL ��� 1 colony; Rio de Janeiro, Angra Reis, Ilhota dos Porcos; 22��58���46��� S, 44��19���47��� W; 10 m depth; 10 Oct. 1998; T.M.C. Lotufo leg.; ColBio Tun 1245. Description The only colony found was attached to a exposed granitic substrate around 10 m deep. This colony was encrusting and small (2 cm wide, 1 mm thick), orange, but lost most of its color when fixed in formalin (Fig. 3A). The tunic is malleable and delicate, with a wide cloacal cavity that extends from the thorax to the region of the esophago-rectal peduncle. Only one common cloacal aperture was seen in this specimen; it is broad with a smooth margin. Spicules, in low density, almost unnoticeable, are mainly restricted to the surface layer of the tunic. Spicules are 20 to 30 ��m in diameter, with 10���12 (in cross section) conical, pointed rays (Fig. 3B). SEM images of the spicules could not be made because of their scarcity and the small size of the colony. Zooids are orangish, about 1.5 mm long. Twelve muscle fibers run longitudinally along each side of the thorax. The oral siphon is 0.15���0.33 mm long with six rounded lobes. The atrial aperture is very short and opens between the third and fourth rows of the pharyngeal stigmata. The pharyngeal stigmata formula is 10���12, 10, 10, 9���10 per half row. The lateral thoracic organ is round, not salient, usually at about the third row of stigmata, occasionally at the second row, close to the endostyle (Fig. 3C). The stomach is slightly elongated and is not overlapped by the intestinal loop. The testis has three oval follicles, overlain by three open turns of the sperm duct (Fig. 3D). Most of the larvae we found were immature. Larvae are oval, yellowish, with about 0.8 mm in trunk length, without vesicles. The tail curves about halfway around the trunk. There are three anterior adhesive papillae with long peduncles. Nine to eleven short, digitiform ampullae are on each side of the larva. The sensorial vesicle is mid-dorsal, with the statocyte somewhat anterior and ventral to the ocellus (Fig. 3E). Remarks Although this species is being described from one single colony, its characters were different enough from those of other known species. Leptoclinides lotufoi sp. nov. is different from the other Atlantic congeners by having the following characteristics: few spicules restricted to the surface of the colony, few testicular follicles and turns of the sperm duct, and many ectodermal ampullae in the larvae. A few other species of Leptoclinides can have many ectodermal ampullae. The Australian L. brandi Kott, 2001 has a granular colony surface with a high density of spicules and smaller larvae with eight pairs of ampullae. Leptoclinides durus Kott, 2001 has many spicules and larger larvae with eight pairs of ampullae. Leptoclinides echinus Kott, 2001 has more testicular follicles (about 15) and larger larvae with eight pairs of ampullae. From New Caledonia, L. multipapillatus Monniot, 1989 has more testicular follicles, more turns of the sperm duct and more than 20 ectodermal ampullae (Monniot 1989; Kott 2001).

UID/EEA/00066/203 knowing how to identify terrain types is especially important in the autonomous navigation, mapping, decision making and emergency landings areas. For example, an unmanned aerial vehicle (UAV) can use it to find a suitable landing position or to cooperate with other robots to navigate across an unknown region. Previous works on terrain classification from RGB images taken onboard of UAVs shown that only static pixel-based features were tested with a considerable classification error. This paper presents a computer vision algorithm capable of identifying the terrain from RGB images with improved accuracy. The algorithm complement the static image features and dynamic texture patterns produced by UAVs rotors downwash effect (visible at lower altitudes) and machine learning methods to classify the underlying terrain. The system is validated using videos acquired onboard of a UAV with a RGB camera. publishersversion published

Due to its characteristics, there is a trend in biometrics to use the ECG signal for personal identification. Recent works based on compression models have shown that these approaches are suitable to ECG biometric identification. However, the best results are usually achieved by the methods that, at least, rely on one point of interest of the ECG. In this work, we propose a compression-based non-fiducial method, that uses a measure of similarity, called the Normalized Relative Compression -- a measure related to the Kolmogorov complexity of strings. Our method uses extended-alphabet finite-context models (xaFCMs) on the quantized first-order derivative of the signal, instead of using directly the original signal, as other methods do. We were able to achieve state-of-the-art results on a database collected at the University of Aveiro, which was used on previous works, making it a good preliminary benchmark for the method., arXiv admin note: text overlap with arXiv:1709.07346

Angiogenesis - the growth of new blood vessels from a pre-existing vasculature - is key in both physiological processes and on several pathological scenarios such as cancer progression or diabetic retinopathy. For the new vascular networks to be functional, it is required that the growing sprouts merge either with an existing functional mature vessel or with another growing sprout. This process is called anastomosis. We present a systematic 2D and 3D computational study of vessel growth in a tissue to address the capability of angiogenic factor gradients to drive anastomosis formation. We consider that these growth factors are produced only by tissue cells in hypoxia, i.e. until nearby vessels merge and become capable of carrying blood and irrigating their vicinity. We demonstrate that this increased production of angiogenic factors by hypoxic cells is able to promote vessel anastomoses events in both 2D and 3D. The simulations also verify that the morphology of these networks has an increased resilience toward variations in the endothelial cell's proliferation and chemotactic response. The distribution of tissue cell`s and the concentration of the growth factors they produce are the major factors in determining the final morphology of the network.

© 2016 Taylor & Francis. Huntington disease (HD) is a neurodegenerative condition with prominent motor (including oculomotor), cognitive, and psychiatric effects. While neuropsychological deficits are present in HD, motor impairments may impact performance on neuropsychological measures, especially those requiring a speeded response, as has been demonstrated in multiple sclerosis and schizophrenia. The current study is the first to explore associations between oculomotor functions and neuropsychological performance in HD. Participants with impaired oculomotor functioning performed worse than those with normal oculomotor functioning on cognitive tasks requiring oculomotor involvement, particularly on psychomotor speed tasks, controlling for covariates. Consideration of oculomotor dysfunction on neuropsychological performance is critical, particularly for populations with motor deficits.

A mixed, homogenous and closed group of ten children ages ranging from ten to eleven years, with the same complaint, was gathered and selected according to heir interest in participating in the research and as a result of the semi-directed interview technique of Bleger (1993). They regularly attend the Recrian?a, project of the Instituto Esperan?a in Valinhos-SP which hosts them after their regular school period and aims at developing a preventive work through informal education. Twelve sixty-minute sessions, three times a week, for a month were held. In those sessions, percussive musical instruments were used as a means to encourage them to accomplish the proposed musical task, a recording equipment being used to assist in the transcription of the meetings. The analysis of the content was based on the Mathieu technique (1967) as used in qualitative research - which goes beyond the mere description of the contents with the application of inferences that allow a more detailed interpretation, and which was conducted by two psychoanalysis-group expert psychologists. We conclude that music was a facilitator of the group psychodiagnosis technique in that the children could express and be self conscious about their feelings, develop a sense of belonging, be able to work on their inhibitions, increase their ability to socialize , strength their ego, which enabled to conduct their psychodiagnosis. Compreens?o do funcionamento de um grupo de crian?as, atrav?s da aplica??o da t?cnica grupo de psicodiagn?stico (Ka?s & Anzieu, 1989), onde levantamos a hip?tese do uso da m?sica como facilitadora das express?es emocionais. Foi formado um grupo de dez crian?as, com idades entre dez e onze anos, misto, homog?neo e fechado, com a mesma queixa, selecionados conforme seu interesse na participa??o e a partir da t?cnica de entrevista semidirigida de Bleger (1993). S?o freq?entadores do projeto Recrian?a, do Instituto Esperan?a em Valinhos-SP, que os acolhe no per?odo oposto ao escolar, desenvolvendo um trabalho preventivo atrav?s da educa??o informal. Foram realizadas doze sess?es de sessenta minutos, tr?s vezes por semana durante um m?s, onde foram utilizados instrumentos musicais percussivos como incentivo ? realiza??o da tarefa musical e um gravador de som para auxiliar nas transcri??es dos encontros. A an?lise do conte?do se deu atrav?s da t?cnica de Mathieu (1967) utilizada em pesquisas de cunho qualitativo, que ultrapassa a simples descri??o dos conte?dos com a aplica??o de infer?ncias que possibilitam uma interpreta??o aprofundada, a qual foi realizada por dois psic?logos com conhecimento de psican?lise de grupo. Conclu?mos que a m?sica foi facilitadora da t?cnica de grupo psicodiagn?stico fazendo com que as crian?as expressassem seus sentimentos e se conscientizassem deles, que atingissem o sentimento de pertin?ncia grupal, que elaborassem suas inibi??es, que ampliassem sua capacidade de sociabilidade, que fortificassem seu ego, sendo poss?vel realizar seu psicodiagn?stico.

Journal of molecular biology 433(9), 166899 (2021). doi:10.1016/j.jmb.2021.166899, Retinoic acid receptors (RARs) and retinoid X receptors (RXRs) form heterodimers that activate target gene transcription by recruiting co-activator complexes in response to ligand binding. The nuclear receptor (NR) co-activator TIF2 mediates this recruitment by interacting with the ligand-binding domain (LBD) of NRs trough the nuclear receptor interaction domain (TIF2NRID) containing three highly conserved ��-helical LxxLL motifs (NR-boxes). The precise binding mode of this domain to RXR/RAR is not clear due to the disordered nature of TIF2. Here we present the structural characterization of TIF2NRID by integrating several experimental (NMR, SAXS, Far-UV CD, SEC-MALS) and computational data. Collectively, the data are in agreement with a largely disordered protein with partially structured regions, including the NR-boxes and their flanking regions, which are evolutionary conserved. NMR and X-ray crystallographic data on TIF2NRID in complex with RXR/RAR reveal a multisite binding of the three NR-boxes as well as an active role of their flanking regions in the interaction., Published by Elsevier, Amsterdam [u.a.]
