A dengue é causada pelo Vírus da dengue (VDEN - Flaviviridae, Flavivirus) e é considerada a arbovirose mais difundida no mundo. Atualmente, não há um animal que sirva como modelo para estudos sobre a patogênese do VDEN. Para investigar a susceptibilidade da espécie Callithrix penicillata ao VDEN foram inoculados amostras do VDEN-3 e do VDEN-2 de isoladas de casos humanos fatais. Para tal, vinte e dois animais foram infectados com VDEN-3 (3,23 × 103 PFU/mL) e, sessenta dias após a infecção (d.p.i.), 11 deles foram secundariamente infectados com VDEN-2 (4,47 × 104 PFU/mL). Sangue, plasma e soro, foram coletados diariamente durante os primeiros sete dias e em 15, 20, 45 e 60 d.p.i.. Foram investigados a produção de anticorpos IgM e inibidores da hemaglutinação, assim como foram análisados parâmetros hematologicos e bioquímicos e o perfil sérico de citocinas (IL-6, TNF-, IL-2, IFN-α, IL-4 e IL-5). A infecção primária (VDEN-3) revelou anticorpos IgM (15- 20 d.p.i.), anticorpos IH (15-60 d.p.i.), aumento dos níveis de TNF-α e IFN-γ e diminuição da IL-5. Na infecção secundária (VDEN-2), foi detectado anticorpos IgM (15-20 d.p.i.), anticorpos IH (15-60 d.p.i.) e diminuição dos níveis de IL-6, TNF-α, de IFN-γ e IL-5. Além disso, foi observado em ambas infecções leucopenia, neutropenia, linfocitopenia, monocitopenia, trombocitopenia, e aumentou da AST. O aumento dos níveis de INF-γ e TNF- α indicaram a ativação da resposta inflamatória, com a diferenciação para a resposta celular e supressão da proliferação de citocinas características da resposta humoral. A presença de anticorpos neutralizantes pode ter ocasionado a supressão da resposta inflamatória na infecção secundária o que pode ter levado a ausência de sinais de Febre Hemorrágica do Dengue/Sindrome do Choque do Dengue (FHD/SCD) durante a infecção secundária (VDEN- 2). Os resultados indicam que o primatas não humanos da espécie Callithrix penicillata demonstraram susceptibilidade à cepas de VDEN de origem humana, sugerindo que esses animais são um bom modelo para estudos da resposta imunológica da Febre do Dengue (FD), assim como para a avaliação de uma vacina tetravalente.

CONTEXTO:Translocações robertsonianas (TR) estão entre os rearranjos estruturais balanceados mais comuns em humanos e compreendem a fusão da cromatina completa do braço longo de dois cromossomos acrocêntricos. No entanto, são raras as translocações não Robertsonianas envolvendo esses cromossomos.RELATO DE CASO:Nós descrevemos uma translocação não balanceada de novo envolvendo os cromossomos 15 e 21. A recém-nascida era filha de uma mãe de 29 anos e de um pai de 42 anos, casal não consanguíneo. Os achados clínicos levaram ao diagnóstico de síndrome de Down (SD) com defeitos cardíacos congênitos graves (persistência do canal arterial e defeito do septo atrioventricular completo), além de baixos comprimento e peso ao nascimento (< 5o e < 10o percentil em curvas de medidas específicas para SD, respectivamente). A análise citogenética convencional revelou o cariótipo 46,XX,der(15)(15pter→15q26.2

Introduction: The myofascial pain syndrome (SDM) is one of the most common causes of musculoskeletal pain. One of the possible treatments for SDM is the type of physiotherapy myofascial manipulation. Objective: This study aimed to analyze the effect of manipulative technique with myofascial pain threshold before and after applying the technique in athletes during competition period. Methods: Participated in the study 62 subjects of both genders, aged between 14 and 38 (19.64 + 4.89), who had myofascial pain syndrome, 32 oh the treatment group and 30 divided equally between control group and the placebo group. All were athletes and operated by the Department of Sport and Leisure in the city of Marilia – SP and were in competitive period. The volunteers were evaluated according to their musculoskeletal symptoms to prove the necessity of performing the technique of myofascial manipulation. Confi rmed the need to assess the pressure pain threshold (LDP) using a digital dynamometer. After the measurement, patients underwent treatment or using the technique of myofascial manipulation, or a sliding surface for the placebo or no treatment for the control group followed by the immediate reassessment of the LDP. Results: The results were normalized by Kolmogrov-Smirnov test (KS). Through the ANOVA test found no differences between the initial LDP thresholds between groups. To compare pre and post LDP of the three groups we used the paired t test. Signifi cant difference (p=0.0001) between the values of pain threshold before and after application of myofascial manipulation for the treated group and not signifi cant for the control group (p=0.45) and placebo (p=0.16). Conclusion: We conclude then that the myofascial manipulation technique is able to increase pain threshold after micro-musculoskeletal injuries in athletes in competitive period.

The Caudal Cervical Spondylomyelopathy, also known as “Wobbler syndrome” is a neurological disorder that affects mainly breeds of large and giant size, especially Doberman pinsher and Great danes. Its aetiology is multifactorial and leads to a narrowing of the spinal canal by morphological and positional caudal cervical vertebrae (C5, C6 and C7), causing compression of the spinal cord and nerve roots. The clinical signs presented by the affected animals are progressive ataxia of hindlimbs and, later, the forelimbs, sometimes progressing to tetraparesis. Neck pain may be present. The diagnosis is made through the association of clinical signs and diagnostic imaging such as radiography, myelography, computed tomography and magnetic resonance imaging. According to the classification of the lesion obtained by imaging examinations, the conservative or surgical treatment is established and the prognosis is variable in accordance with the degree of affection of the spinal cord

The means of mass communication are powerful tools to the spread of a concept as persuasion is a strong characteristic of discourses that gather around the sphere of communication, especially in advertising discourses. By the end of the 90’s, the advertisement “Down: the worst syndrome is prejudice”, did great success approaching prejudice / pre-concept in a subtle and innovative way, due its outstanding purpose and style inserting two boys in a carousel, one is a street child, the other a Down syndrome patient. The advertisement reveals a speak project of diffusion and spread of ideas that down syndrome patients are capable of dealing and supporting a routine full of activities, making a opposition to the campaigns and ideas that, in spite of raising the respect towards these kids, only contributed with the attenuation of their handicaps. Our objective is to investigate the presence of these social values in the quoted audio-visual material, and for that we’ve searched the contextualization of the advertisement in its own time period. The theory and methodological aspects got their base in Bakhtinian studies and concepts; we used the concepts of discourse gender, chronotope and mainly dialogism and enunciation. We analyzed the style utilized in the advertisement, the dialogue between the politically correct and the prejudice speeches, the verbal discourse of the music that flows with the progress of the enunciation, the non-verbal discourse of the photography (nostalgic, producing effects of sense in its relation with memory), the chronotope present in the utilization of the carousel and its significations. We concluded that the accession of the recipient, in it responsive comprehension of the enunciation at hand, is an effect produced by the well-succeded addition of these different types of discourses

Vulnerability of patients with Down syndrome (DS) to oxidative stress and damage has been attributed to the overexpression of the superoxide dismutase gene, which is located in the triplicated critical region 21q22.2 of chromosome 21. The objective of this study was to investigate enzymatic and non-enzymatic antioxidant systems and levels of biomarkers of oxidative damage in saliva of patients with DS. Saliva samples were collected from 30 patients with DS and 30 controls, ranging in age from 14 to 24 years. The following parameters were analyzed: superoxide dismutase activity, concentration of malondialdehyde, carbonylated proteins, uric acid, vitamin C and total protein, peroxidase activity, and total antioxidant capacity. Patients with DS presented significantly higher superoxide dismutase activity and malondialdehyde levels than controls (p<0.05). On the other hand, no difference in carbonylated proteins or antioxidants (uric acid, vitamin C, peroxidase, and total antioxidant capacity) was observed between DS patients and controls (p>0.05). Patients with DS also presented higher salivary total protein content (p<0.05). In conclusion, despite similar antioxidant levels patients with DS are more vulnerable to oxidative stress in saliva as indicated by a significant increase in malondialdehyde concentration and superoxide dismutase activity
