The effects of a program of teaching games in psychobiological aspects of elderly women

OBJECTIVE:To investigate the effects of a program of teaching games (TG) in psychobiological aspects of elderly women.METHODS:53 female elderly volunteers were distributed in two groups: Active group (n=27) participating of a TG program composed by adapted sporting activities for six months, three times a week, for one hour; Control group (n=26) was told not to change their routine and not to start any physical exercise regular program. The mean (±standard-deviation) of height, weight, BMI were: 67.91±6.11years; 1.55±0.06cm; 80.68±8.45kg; and 33.41±2.62kg/m2, respectively. Before and after of program proposed, the volunteers answered a psychobiology battery composed by: mini-mental state examination; Epworth sleepiness scale; Pittsburgh sleep quality index; SF-36; geriatric depression scale; STAI-trait/state; Brunel mood scale; habitual physical activity; and body shape questionnaire.RESULTS:After the intervention period, the Active group showed better human psychobiological answers, represented by lower scores of anxiety and depression, better quality of life with increased functional capacity and vitality, and improved body image, when compared to the Control group.CONCLUSION:These results suggest that a 6-month TG program improves psychobiological aspects of elderly women.OBJETIVO:Investigar o efeito de um programa de jogos pré-desportivos (JPD) nos aspectos psicobiológicos de idosas.MÉTODOS:53 voluntárias idosas foram distribuídas em dois grupos: grupo Ativo (n=27) - submetido a um programa de JPD composto por atividades esportivas adaptadas, por seis meses, três vezes semanais, por uma hora; grupo Controle (n=26) - orientado a não modificar sua rotina, não se engajando em nenhum programa de atividade física sistematizada. A média (±desvio-padrão) da idade, estatura, massa corporal, índice de massa corpórea foram: 67,91±6,11anos; 1,55±0,06cm; 80,68±8,45kg; e 33,41±2,62kg/m2, respectivamente. Antes e após o início do programa proposto, as voluntárias responderam a uma bateria psicobiológica composta por: miniexame do estado mental; escala de sonolência de Epworth; índice de qualidade de sono de Pittsburgh; SF-36; escala geriátrica de depressão; IDATE-Traço/Estado; escala de humor de Brunel; nível de atividade física habitual; e questionário de imagem corporal.RESULTADOS : Após o término do período experimental, o grupo Ativo apresentou melhores respostas psicobiológicas de humor, representadas por menores escores de ansiedade, menores escores de depressão, melhor qualidade de vida com aumento da capacidade funcional e da vitalidade, além de melhora da imagem corporal, quando comparado ao grupo Controle.CONCLUSÃO:Os resultados sugerem que um programa de seis meses de JPD produz impacto positivo nos aspectos psicobiológicos de idosas.Universidade Federal de São Paulo (UNIFESP) Centro de Estudos em Psicobiologia e Exercicio Departamento de PsicobiologiaUniversidade Federal de São Paulo (UNIFESP) Departamento de Ciencias do Movimento HumanoUniversidade Federal de São Paulo (UNIFESP) Laboratorio de Treinamento Fisico Experimental Departamento de BiocienciasUNIFESP, Centro de Estudos em Psicobiologia e Exercicio Depto. de PsicobiologiaUNIFESP, Depto. de Ciencias do Movimento HumanoUNIFESP, Laboratorio de Treinamento Fisico Experimental Depto. de BiocienciasSciEL

A pilot study to evaluate the expression of microRNA‐let‐7a in patients with intestinal‐type sinonasal adenocarcinoma

Despite its histological resemblance to colorectal adenocarcinoma, there is little information about the molecular events involved in the pathogenesis of intestinal-type sinonasal adenocarcinoma (ITAC). The present study investigated the possible role and clinical value of microRNA (miR)-let-7a, a head and neck squamous cell carcinoma-related miR, in a well-characterized and homogeneous cohort of patients with ethmoidal ITAC associated with occupational exposure, treated by primary surgery. miR-let-7a expression levels were analyzed in 23 pairs of ethmoidal ITAC and adjacent normal formalin-fixed paraffin-embedded tissues by reverse transcription-quantitative PCR. The expression was evaluated in tumor and healthy tissues according to: Tumor grade (G) of differentiation and extension, and pTNM stage, and presence/absence of recurrence. Comparisons within and between groups were performed using two-tailed Student's paired t-test and one-way ANOVA with Tukey's post hoc test. P<0.05 was considered to indicate a statistically significant difference. miR-let-7a expression in ethmoidal ITAC tissues was significantly lower than that in adjacent normal tissues (P<0.05; mean expression level +/- SD, 1.452707 +/- 1.4367189 vs. 4.094017 +/- 2.7465375). miR expression varied with pT stage. miR-let-7a was downregulated (P<0.05) in advanced stages (pT3-pT4) compared with earlier stages (pT1-pT2). Furthermore, downregulation of miR-let-7a in ITAC was associated with poorly-differentiated (G3) cancer (P<0.05). No other associations were observed between miR-let-7a expression and the other clinicopathological parameters, including disease-free survival. In conclusion, downregulation of miR-let-7a in ITAC was associated with advanced-stage (pT3 and pT4) and poorly-differentiated (G3) disease, suggesting that the mutation of this gene, combined with additional genetic events, could serve a role in ITAC pathogenesis

Lung structure and function similarities between primary ciliary dyskinesia and mild cystic fibrosis: a pilot study

BACKGROUND: Primary ciliary dyskinesia (PCD) and cystic fibrosis (CF) are increasingly compared. There are no chest magnetic resonance imaging (MRI) comparative studies of PCD and CF. We assessed clinical, functional, microbiological and MRI findings in PCD and mild CF patients in order to evaluate different expression of lung disease. METHODS: Twenty PCD (15.1 years) and 20 CF subjects with mild respiratory impairment (16 years, 70% with pancreatic insufficiency) underwent MRI, spirometry, and sputum cultures when clinically stable. MRI was scored using the modified Helbich system. RESULTS: PCD was diagnosed later than CF (9.9 versus 0.6 years, p = 0.03), despite earlier symptoms (0.1 versus 0.6 years, p = 0.02). In the year preceding the study, patients from both groups underwent two systemic antibiotic courses (p = 0.48). MRI total scores were 11.6 ± 0.7 and 9.1 ± 1 in PCD and CF, respectively. FEV1 and FVC Z-scores were -1.75 (range, -4.6-0.7) and -0.6 (-3.9-1.8) in PCD, and -0.9 (range, -5.4-2.3) and -0.3 (-3.4-2.5) in CF, respectively. No difference was found between lung function or structure, despite a higher MRI subscore of collapse/consolidation in PCD versus CF (1.6 ± 0.1 and 0.6 ± 0.2, p < 0.001). These findings were confirmed after data-control for diagnostic delay. Pseudomonas aeruginosa and Staphylococcus aureus were more frequent in CF than in PCD (p = 0.05 and p = 0.003, respectively). CONCLUSIONS: MRI is a valuable radiation-free tool for comparative PCD and CF lung disease assessment. Patients with PCD may exhibit similar MRI and lung function changes as CF subjects with mild pulmonary disease. Delay in PCD diagnosis is unlikely the only determinant of similarities

Tetrodotoxin-insensitive electrical field stimulation-induced contractions on crotalus durissus terrificus corpus cavernosum

FAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOCNPQ – CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOReptiles are the first amniotes to develop an intromitent penis, however until now the mechanisms involved in the electrical field stimulation-induced contraction on corpora cavernosa isolated from Crotalus durissus terrificus were not investigated. Crotalus and rabbit corpora cavernosa were mounted in 10 mL organ baths for isometric tension recording. Electrical field stimulation (EFS)-induced contractions were performed in presence/absence of phentolamine (10 mu M), guanethidine (30 mu M), tetrodotoxin (1 mu M and 1mM), A-803467 (10 mu M), 3-iodo-L-Tyrosine (1 mM), salsolinol (3 mu M) and a modified Krebs solution (equimolar substitution of NaCl by N-methyl-D-glucamine). Immuno-histochemistry for tyrosine hydroxylase was also performed. Electrical field stimulation (EFS; 8 Hz and 16 Hz) caused contractions in both Crotalus and rabbit corpora cavernosa. The contractions were abolished by previous incubation with either phentolamine or guanethidine. Tetrodotoxin (1 mu M) also abolished the EFS-induced contractions of rabbit CC, but did not affect EFS-induced contractions of Crotalus CC. Addition of A-803467 (10 mu M) did not change the EFS-induced contractions of Crotalus CC but abolished rabbit CC contractions. 3-iodo-L-Tyrosine and salsolinol had no effect on EFS-induced contractions of Crotalus CC and Rabbit CC. Replacement of NaCl by N-Methyl-D-glucamine (NMDG) abolished EFS-induced contractions of rabbit CC, but did not affect Crotalus CC. The presence of tyrosine hydroxylase was identified in endothelial cells only of Crotalus CC. Since the EFS-induced contractions of Crotalus CC is dependent on catecholamine release, insensitive to TTX, insensitive to A803467 and to NaCl replacement, it indicates that the source of cathecolamine is unlikely to be from adrenergic terminals. The finding that tyrosine hydroxylase is present in endothelial cells suggests that these cells can modulate Crotalus CC tone128FAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOCNPQ – CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOCNPQ – CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO2011/11828-4140731/2013-

Behavioral responses in people affected by alcohol use disorder and psychiatric comorbidity: correlations with addiction severity

Aim. In this study, we investigated in people suffering from alcohol use disorder (AUD) with or without dual diagnosis (concomitant psychiatric disability) how they feel their dependence condition. We predicted that AUD people with a dual diagnosis could feel potentiated their addiction.Methods. Alcohol habits and psychiatric conditions of 183 AUD men and 62 AUD women were measured by using the DSM-5, the severity of alcohol dependence questionnaire (SADQ), the alcohol anamnesis and psychiatric examination by the symptom check list 90-R (SCL-90-R).Results. We have shown that alcohol drinking does not correlate with both psychiatric examination and self-reported psychopathology. SADQ shows that severe alcohol dependence correlates with highest psychiatric symptoms and with the levels of alcohol consumption.Conclusions. This finding suggests that high SADQ scores may represent a tool to early disclose only patients with dual diagnosis. SADQ may provide information to address pharmacological interventions because revealing aspects of the dark side of addiction potentiated by AUD associated psychopathology.

Mineralocorticoid Receptor Modulation by Dietary Sodium Influences NAFLD Development in Mice

Introduction and Objectives Nonalcoholic-fatty-liver disease (NAFLD) is considered the hepatic manifestation of metabolic syndrome (MetS). Mineralocorticoid receptor (MR) activation is associated with increased risk of MetS but few studies have assessed the role of liver MR on NAFLD. We aimed to evaluate the effect of MR modulation by sodium intake in liver injury in experimental models of NAFLD. Materials and Methods C57BL/6J mice were fed either a high-fat-diet (HFD) or a choline/methionine deficient (MCD) diet with different sodium concentrations. Hepatic concentration of lipid species, serum aldosterone levels, expression of MR, proinflammatory and profibrotic markers and liver histology were assessed. Results Mice fed with High-Na+/HFD showed a lower MR expression in liver (p = 0.01) and less steatosis on histology (p = 0.04). Consistently, animals from this group exhibited lower levels of serum aldosterone (p = 0.028) and lower hepatic triglyceride content (p = 0.008). This associated to a reduced expression of lipogenic genes, significant changes in lipid subspecies, lower HOMA-IR (p < 0.05), and lower expression of pro-inflammatory and profibrotic markers compared to those mice fed a Low-Na+/HFD. Additionally, mice fed a High-Na+/HFD showed higher expression of salt-inducible kinase (SIK)-1 and lower expression of serum-and-glucocorticoid-inducible kinase (SGK)-1. Similar results were observed with the MCD diet model. Conclusion We identified in two experimental models of NAFLD that High-Na+ diet content is associated to lower serum aldosterone levels and hepatic MR downregulation, associated to decreased steatosis and reduced de novo hepatic lipogenesis, proinflammatory and profibrotic markers. Decreased activation of hepatic MR seems to generate beneficial downstream inhibition of lipogenesis in experimental NAFLD.This work was funded, in part, by grants from the Chilean Government [FONDECYT #1150327 and #1191145 to M.A.; #1200227 to JPA; #1190419 to R.B and #1191183 to F.B.; #1211879 to D.C.) and the Comisión Nacional de Investigación Científica y Tecnológica (CONICYT, AFB170005, CARE Chile UC)].

Why the Mexican Oyster Fishery in the Gulf of Mexico Is Underdeveloped?

The Mexican Oyster fishery in the Gulf of Mexico annually produces only 50,000 MT, 95% of Mexico oyster production. Oyster production has fallen drastically in most coastal lagoons, this decline has been attributed to factors as overfishing, mismanagement of natural oyster beds, environmental degradation and lagoons pollution. This work proposes strategies for oyster fishery management on Gulf of Mexico littoral. In order to achieve this goal oyster fishery diagnose for Tamaulipas, Veracruz, Tabasco and Campeche states were made for evaluation of ecological, economics, legal and social aspects trough information sources as statistical yearbooks, databases, and published information relative to regional oyster fishery, simultaneously visits to landing places where made and inquiries to production units, directives, fishermen and decision makers were done. Collected information was grouped and analyzed with SWOT analysis. Oyster fishery is carried on in 20 coastal ecosystems where works 51 production units with 2,955 active oyster fishermen. In every visited site were observed water pollution, coastal deforestation and or overfishing. National and international oysters markets cannot grow for several reasons including sanitary quality; there are no efficient models for oyster beds administration, no infrastructure for give oyster products additional value. Some of the strategies for solve these difficulties are, to make local diagnosis and promote social organization for control of water quality, market research for oyster products and laboratory seed production, register efficiently and responsibly catch statistics, to make official norms on size catch, fishing gear, fishing, reception, packing, commercialization, culture techniques, and cultured oyster sizes, these strategies and other programs may permit sustainable and biotechnological development in oyster fishery.Keywords: Fisheries Economics, Fish and Aquaculture Sectors Development, Fisheries Dynamic

First report of fibropapillomatosis (FP) and Chelonid alphaherpesvirus 5 (ChHV5) in a green sea turtle (Chelonia mydas) from the historically fibropapillomatosis-free Fernando de Noronha Archipelago, Northeastern Brazil

A fibropapilomatose (FP) é uma doença infecciosa causada pelo Chelonid alphaherpesvirus 5 (ChHV5). No entanto, as manifestações clínicas da doença são consideradas multifatoriais. Esta doença é monitorada atualmente em populações de tartarugas marinhas nos EUA, Austrália, Caribe e Brasil. Desde 2000, o Projeto TAMAR/Fundação Projeto TAMAR analisa a presença de FP em nove estados da costa brasileira e ilhas oceânicas, incluindo o arquipélago de Fernando de Noronha, uma área historicamente livre de FP. Um total de 4.435 indivíduos de Chelonia mydas foram monitorados de 2010 a 2016 e 43 amostras de pele foram analisadas para detectar ChHV5 em 2012 e 2014 com o objetivo de avaliar a presença do vírus em tecidos sem FP, usando uma PCR qualitativa para detecção de sequências do gene da UL30 polimerase. Em 2015, uma tartaruga verde (C. mydas) foi relatada com um nódulo ocular bilateral caracterizado como FP. Amostras de tecido foram coletadas durante sua reabilitação e procedimento cirúrgico para remover o tumor. A caracterização parcial de uma sequência de 454 bp do gene UL30 polimerase detectou ChHV5 anteriormente relatado em outras áreas da costa atlântica brasileira. Após estes achados, de janeiro de 2017 a março de 2020, um total de 360 indivíduos de C. mydas foram monitorados e nenhum caso de FP foi registrado. Este é o primeiro relato de FP e a primeira caracterização de ChHV5 no arquipélago de Fernando de Noronha, uma questão preocupante e que ressalta a importância do monitoramento desta doença em áreas historicamente livres de FP na costa atlântica brasileira. Fibropapillomatosis (FP) is an infectious disease caused by Chelonid alphaherpesvirus 5 (ChHV5). Nevertheless, its clinical manifestations are considered multifactorial. Due to its relevance, FP is currently monitored in sea turtle populations in the United States, Australia, Caribbean, and Brazil. Between 2000 and 2020, the TAMAR Project/ TAMAR Project Foundation analyzed the prevalence of FP in nine states and oceanic islands along the Brazilian coast, including Fernando de Noronha Archipelago (FNA), a historically FP-free area. A total of 4,435 green sea turtles (Chelonia mydas) were monitored from 2010 to 2016. Additionally, in 2012 and 2014, 43 FP-free skin samples were analyzed for ChHV5 using a qualitative PCR for the UL30 polymerase (pol) sequence. In 2015, a bilateral ocular nodule characterized as an FP tumor was reported in one of the monitored individuals undergoing rehabilitation. Tissue samples were collected following surgical removal of the tumor. Characterization of a 454 bp UL30 polymerase gene revealed a ChHV5 sequence previously reported in other areas of the Atlantic Brazilian coast. In the years following this finding from January 2017 to March 2020, a total of 360 C. mydas were monitored in the same area and no FP tumors were detected. This is the first report of FP and the first detection of ChHV5 in FNA, a finding of great concern considering this site’s historical absence of FP occurrence. This study highlights the importance of monitoring this disease in historically FP-free areas of the Brazilian Atlantic coast

Pranlukast Antagonizes CD49f and Reduces Sternness in Triple-Negative Breast Cancer Cells

Introduction: Cancer stem cells (CSCs) drive the initiation, maintenance, and therapy response of breast tumors. CD49f is expressed in breast CSCs and functions in the maintenance of stemness. Thus, blockade of CD49f is a potential therapeutic approach for targeting breast CSCs. In the present study, we aimed to repurpose drugs as CD49f antagonists. Materials and Methods: We performed consensus molecular docking using a subdomain of CD49f that is critical for heterodimerization and a collection of pharmochemicals clini-cally tested. Molecular dynamics simulations were employed to further characterize drug-target binding. Using MDA-MB-231 cells, we evaluated the effects of potential CD49f antagonists on 1) cell adhesion to laminin; 2) mammosphere formation; and 3) cell viability. We analyzed the effects of the drug with better CSC-selectivity on the activation of CD49f-downstream signaling by Western blot (WB) and co-immunoprecipitation. Expressions of the stem cell markers CD44 and SOX2 were analyzed by flow cytometry and WB, respectively. Transactivation of SOX2 promoter was evaluated by luciferase reporter assays. Changes in the number of CSCs were assessed by limiting-dilution xenotransplantation. Results: Pranlukast, a drug used to treat asthma, bound to CD49f in silico and inhibited the adhesion of CD49f+ MDA-MB-231 cells to laminin, indicating that it antagonizes CD49f-containing integrins. Molecular dynamics analysis showed that pranlukast binding induces con-formational changes in CD49f that affect its interaction with β1-integrin subunit and constrained the conformational dynamics of the heterodimer. Pranlukast decreased the clonogenicity of breast cancer cells on mammosphere formation assay but had no impact on the viability of bulk tumor cells. Brief exposure of MDA-MB-231 cells to pranlukast altered CD49f-dependent signaling, reducing focal adhesion kinase (FAK) and phosphatidylinositol 3-kinase (PI3K) activation. Further, pranlukast-treated cells showed decreased CD44 and SOX2 expression, SOX2 promoter transacti-vation, and in vivo tumorigenicity, supporting that this drug reduces the frequency of CSC. Conclusion: Our results support the function of pranlukast as a CD49f antagonist that reduces the CSC population in triple-negative breast cancer cells. The pharmacokinetics and toxicology of this drug have already been established, rendering a potential adjuvant therapy for breast cancer patients
