Plants have long been used in traditional medicine to treat illnesses. Nevertheless, their chemical diversity requires studies to establish the extract dosage and its safe use. Pseudobombax parvifolium, an endemic species of the Brazilian Caatinga biome, is commonly used in folk medicine, due to its anti-inflammatory properties related to cellular oxidative stress; however, its biological properties have scarcely been studied. In this study, we chemically characterized the P. parvifolium hydroalcoholic bark extract (EBHE) and evaluated its cytotoxic, mutagenic, and preclinical aspects, as well as its antioxidant effect. Our phytochemical analysis revealed a significative total polyphenol content and identified loliolide for the first time in this species. Cytotoxicity, mutagenicity, and acute oral and repeated dose indicated no toxic effects on cell culture, Drosophila melanogaster, and Wistar rat exposure to different EBHE concentrations, respectively. Furthermore, we observed a significant decrease in lipid peroxidation and a mild hypoglycemic and hypolipidemic effect with repeated oral dosing of EBHE. Although there were no significant changes in glutathione content, we did observe a significant increase in superoxide dismutase at a dose of 400 mg/kg and in glutathione peroxidase at doses of 100, 200, and 400 mg/kg. These findings suggest that EBHE has potential as a source of bioactive molecules, and it can be used safely in traditional medicine and in the development of herbal medicines for application in the public health system.

LRP5 ,rs3736228 ,T%22">4037C>T ,Type 1 diabetes mellitus - Abstract
Objective: The present study has investigated the association between low-density lipoprotein receptor-related protein 5 (LRP5) 4037C>T polymorphism and type 1 diabetes mellitus (T1DM) susceptibility in a Brazilian population. Subjects and methods: A total number of 134 T1DM patients and 180 normoglycemic individuals (NG) aged 6-20 years were studied. Glycated hemoglobin and glucose levels were determined. Genotyping of LRP5 4037C>T (rs3736228) was performed. Results: T1DM patients showed poor glycemic control. Genotypes in the codominant (CT: OR = 2.99 [CI 95%: 1.71-5.24], p < 0.001; TT: OR = 5.34 [CI 95%: 1.05-2702], p < 0.001), dominant (CT + TT: OR = 3.16 [CI 95%: 1.84-5.43], p < 0.001) and log-additive (OR = 2.78 [CI 95%: 1.70-4.52], p < 0.001) models, and LRP5 4037T allele (OR = 2.88, [CI 95%: 1.78-4.77], p < 0.001) were associated with an increased risk of developing T1DM. LRP5 4037CT and CT+TT carriers in T1DM group showed higher concentrations of serum glucose and glycated hemoglobin when compared with CC carriers. Conclusion: The LRP5 4037C>T may represent a candidate for T1DM susceptibility, as well as poor glycemic control.

BONE density ,TYPE 1 diabetes ,ALBUMINURIA ,AGE ,GLOMERULAR filtration rate - Abstract
Aim: To evaluate glycaemic control and its influence on albuminuria and bone mineral density (BMD) in children and adolescents with type 1 diabetes (T1D).Methods: We collectively assessed 84 T1D children/adolescents (T1D group), aged between 6 and 17 years, and then divided them into two groups according to their glycaemic profile (T1D with good glycaemic control (T1DG group) and T1D with poor glycaemic control (T1DP group)). Serum glucose, glycated haemoglobin, serum urea, serum creatinine, urinary albumin-to-creatinine ratio (ACR), estimated glomerular filtration rate and BMD levels were assessed.Results: Of the patients studied, 77% presented with poor glycaemic control. Patients with T1DP showed an increased ACR (P < 0.001) and a low BMD (P = 0.025) when compared to the T1DG group. In addition, five patients in the T1DP group presented with concomitant albuminuria and a low BMD for their chronological age. Significant negative correlations were identified between the ACR and glycated haemoglobin (r = 0.655, P < 0.001), BMD and glycated haemoglobin (r = -0.262, P = 0.047) and BMD and the ACR (r = -0.631, P = <0.001). In linear regression analysis, the ACR showed a negative effect on BMD (P = 0.044) in the T1D patient group.Conclusion: Poor glycaemic control was correlated with albuminuria, suggestive of a negative effect on bone tissue, leading to a low BMD in children and adolescents with T1D.

Os objetivos do presente trabalho foram estudar a associação de polimorfismos e da expressão do mRNA dos genes TLR2, TLR4, MYD88, IL1B, IL6 e TNFA com a nefropatia diabética em crianças e adolescentes com Diabetes mellitus tipo 1 (DM1), assim como investigar o potencial papel do WT-1 nos exossomos urinários como um biomarcador sensível e não invasivo de dano glomerular nestes pacientes. No total, foram incluídos no estudo 144 crianças e adolescentes com DM1 e 173 indivíduos normoglicêmicos (NG) da mesma faixa etária. Foram pesquisados os polimorfismos dos genes IL6 (-634C>G e -174G>C), IL1B (3954C>T e -511C>T), TNFA (-308G>A) e TLR2 (1350T>C), determinadas as expressões gênicas de IL6, IL1B, TNFA, MYD88, TLR2 e TLR4, e quantificado o WT-1 em exossomos urinários. Além disso, foram avaliados o controle glicêmico, os lipídios séricos e parâmetros laboratoriais de função renal. Os indivíduos com DM1 apresentaram um controle glicêmico insatisfatório e valores aumentados de colesterol total, LDL-colesterol e da relação albumina:creatinina (RAC), quando comparados com os NG (pC foi associado com susceptibilidade ao DM1 (pC pode contribuir para o desenvolvimento do DM1 e da nefropatia diabética, que o TNFA -308G>A pode conferir proteção contra a doença renal induzida pelo DM1 e que o WT-1 nos exossomos urinários seria um indicador precoce de dano em podócitos.

- Abstract
Considering that environmental risk factors substantially contribute to the etiology of orofacial clefts and that knowledge about the characteristics and comorbidities associated with oral clefts is fundamental to promoting better quality of life, this study aimed to describe the risk factors, main characteristics, and comorbidities of a group of patients with cleft lip and/or cleft palate (CL/P) from Rio Grande do Norte (RN), Brazil. Data were obtained from 173 patients with CL/P using a form from the Brazilian database on Orofacial Clefts. Most patients were male with cleft lip and palate and had a normal size and weight at birth; presented few neonatal intercurrent events; and had anemia and respiratory and cardiovascular diseases as main associated comorbidities. They also required timely surgical rehabilitation and multidisciplinary care to stimulate their neuropsychomotor development. In addition, a high frequency of familial recurrence and of parental consanguinity was evidenced in the studied population, especially for the cleft lip and cleft palate type. Other relevant findings were the considerable maternal exposure to alcohol, infections, smoking, and hypertension, as well as low supplementation with vitamins and minerals and deliberate consumption of analgesics, antibiotics, and antihypertensives during pregnancy. Characterization of the CL/P patient profile is essential for the planning of health services and integration among the health professionals involved in the diagnosis and treatment of these malformations. Our results reinforce the need for additional research to confirm the association between environmental factors and the development of orofacial clefts. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The negative effects of type 1 diabetes (T1D) on growth factors of bone metabolism lead to a reduction in bone mineral density. This study aimed to evaluate the association between bone mineral density and insulin-like growth factor 1 (IGF1), insulin-like growth factor 1 receptor (IGF1R) and transforming growth factor beta 1 (TGFB1) expressions in children and adolescents with T1D. Moreover, the influences of age at diagnosis, time since diagnosis, glycaemic control and albuminuria on bone mineral density were investigated.Methods: Eighty-six T1D children/adolescents (T1D group) and ninety normoglycaemic controls (normoglycaemic group) were included. T1D patients were analysed as a whole and also in subsets of patients with good glycaemic control (glycated hemoglobin concentration ≤7.5%) and with poor glycaemic control (glycated hemoglobin concentration >7.5%). Bone mineral density was assessed by dual energy x-ray absorptiometry. Glycaemic control, renal function and bone markers were also assessed. IGF1, IGF1R and TGFB1 expressions were determined in peripheral blood mononuclear cells by real-time polymerase chain reaction.Results: Patients with T1D showed low bone mineral density and poor glycaemic control. Serum total calcium and urinary albumin-to-creatinine ratio were higher in patients with poor glycaemic control compared to those with good glycemic control (p = 0.003 and p = 0.035, respectively). There was a reduction of IGF1, IGF1R and TGFB1 expressions in the T1D patients and in the subset with poor glycaemic control compared to normoglycaemic controls (p < 0.05).Conclusions: The decreased IGF1, IGF1R and TGFB1 expressions in the T1D patients, who presented with T1D at an early age, had been diagnosed with T1D for a longer time, had poor glycaemic control and albuminuria may contribute to low bone mineral density.

Estresse oxidativo ,Plantas medicinais ,Toxicidade ,Fitoterápico - Abstract
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES As plantas medicinais apresentam substâncias bioativas que auxiliam no tratamento das mais diversas doenças e sua utilização para fins terapêuticos é tão antiga quanto a civilização humana. No Brasil, a utilização de plantas medicinais para o cuidado primário da saúde é amplamente disseminada devido a sua grande biodiversidade vegetal, ao seu baixo custo, ao fácil acesso e ao amplo conhecimento popular acerca de seu uso. Contudo, vale ressaltar que grande parte das espécies utilizadas na medicina tradicional não apresentam estudos científicos comprovando sua eficácia, segurança, composição química ou possível toxicidade. Nesse contexto, a espécie Licania rigida Benth pertencente à família Chrysobalanaceae é uma espécie vegetal encontrada no semiárido nordestino, sendo usada na medicina popular para o tratamento de processos inflamatórios e Diabetes. Entretanto, apesar da sua utilização, existem poucos estudos para validar seu potencial farmacológico e toxicológico. Em decorrência disso, o objetivo deste estudo foi avaliar as propriedades toxicológicas do extrato aquoso da Licania rigida através de métodos padronizados de toxicidade oral aguda e subcrônica, mutagenicidade e citotoxicidade, bem como o seu possível efeito protetor contra o estresse oxidativo. O extrato não apresentou nenhum efeito tóxico ou genotóxico nos ensaios in vivo e in vitro após a exposição a diferentes concentrações. No que diz respeito ao efeito antioxidante, o extrato exibiu um possível efeito protetor ao diminuir o nível de malondialdeído (MDA) nos animais tratados; nenhuma mudança significativa foi observada para os níveis de glutationa reduzida (GSH), superóxido dismutase (SOD) e glutationa peroxidase (GPX). Portanto, propõe-se que o extrato de folhas de Licania rigida pode tornar-se um futuro medicamento fitoterápico, entretanto, mais estudos são necessários para validar sua aplicação farmacológica e para o desenvolvimento de novas formulações fitoterápicas. Medicinal plants present bioactive substances that help in the treatment of the most diverse diseases and their use for therapeutic purposes is as old as human civilization. In Brazil, the use of medicinal plants for primary health care is widespread due to its large plant biodiversity, low cost, easy access, and wide popular knowledge about their use. However, it is worth noting that most species used in traditional medicine do not present scientific studies proving their efficacy, safety, chemical composition, or possible toxicity. In this context, the species Licania rigida Benth belonging to the Chrysobalanaceae family is a plant species found in the semiarid northeastern Brazil, being used in folk medicine for the treatment of inflammatory processes and diabetes. However, despite its use, there are few studies to validate its pharmacological and toxicological potential. As a result, the objective of this study was to evaluate the toxicological properties of the aqueous extract of Licania rigida through standardized methods of acute and subchronic oral toxicity, mutagenicity and cytotoxicity, as well as its possible protective effect against oxidative stress. The extract did not show any toxic or genotoxic effect in the in vivo and in vitro assays after exposure to different concentrations. With regard to the antioxidant effect, the extract exhibited a possible protective effect by decreasing the level of malondialdehyde (MDA) in treated animals; no significant changes were observed for reduced glutathione (GSH), superoxide dismutase (SOD) and glutathione peroxidase (GPX) levels. Therefore, it is proposed that Licania rigida leaf extract may become a future herbal medicine, however, further studies are needed to validate its pharmacological application and for the development of new herbal formulations.

Insuficiência cardíaca ,Marcadores ,Expressão gênica ,Infarto agudo do miocárdio - Abstract
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq A insuficiência cardíaca (IC) é uma síndrome progressiva caracterizada pela incapacidade do coração bombear sangue suficiente para os demais tecidos, e sua principal causa é o infarto agudo do miocárdio (IAM). Apesar dos avanços na identificação de marcadores associados ao remodelamento do ventrículo esquerdo (VE), o marcador ideal para uma detecção precoce e acurada da IC isquêmica ainda não foi encontrado. Sendo assim, esse estudo tem como objetivo avaliar a expressão de 13 genes previamente associados ao IAM em pacientes com disfunção ventricular após o IAM comparando-os com aqueles que não tiveram complicações após o IAM. Além disso, esse estudo buscou listar os miRNAs mais frequentemente citados na literatura por estarem relacionados ao desenvolvimento da IC isquêmica e verificar a influencia deles na expressão dos genes estudados. Os pacientes que sofreram IAM prévio foram classificados em dois grupos: disfunção do VE [fração de ejeção do VE (FEVE) ≤ 40%, n = 14] e função do VE normal (FEVE > 40%, n = 14). A expressão de ALOX15, AREG, BCL2A1, BCL2L1, CA1, COX7B, ECHDC3, IL18R1, IRS2, KCNE1, MMP9, MYL4 e TREML4 foram avaliados por RT-PCR. Apenas a expressão de KCNE1 diminuiu no grupo FEVE ≤ 40% (p = 0,007). Foi encontrada correlação positiva entre KCNE1 e fração de ejeção (r = 0,557; p = 0,001). Houve um risco de 12,25 vezes (IC 95%: 1,33 - 113,06; p = 0,027) de disfunção do VE para pacientes com menor expressão de KCNE1. A expressão de KCNE1 mostrou alto AUROC (AUROC: 0,811, IC 95%: 0,642-0,979, p = 0,007), indicando a expressão de KCNE1 como um bom preditor em desfechos cardíacos. Análise da literatura mostrou que os miRNAs mais associados com o desenvolvimento da IC isquêmica são miR-499, miR-1, miR-133a, e miR-208b, sendo o miR-1 já descrito como regulador da expressão do KCNE1, de acordo com banco de dados público miRNet. Dessa forma, este estudo sugere que a expressão de KCNE1, bem como seus mecanismo regulatórios como o miR-1, podem estar relacionados com os níveis de FEVE e, portanto, com o risco de desenvolvimento da IC pós-IAM. Heart failure (HF) is a progressive syndrome characterized by the heart's inability to pump enough blood to other tissues, and its main cause is acute myocardial infarction (AMI). Despite advances in identifying markers associated with left ventricular (LV) remodeling, the ideal marker for early and accurate detection of ischemic HF has not yet been found. Therefore, this study aims to evaluate the expression of 13 genes previously associated with AMI in patients with LV dysfunction after AMI, comparing them with those who had no complications after AMI. In addition, this study sought to summarize the miRNAs most frequently cited in the literature as they are related to the development of ischemic HF and to verify their influence on the expression of the 13 genes. Patients who suffered previous AMI were classified into two groups: LV dysfunction [LV ejection fraction (LVEF) ≤ 40%, n = 14] and normal LV function (LVEF > 40%, n = 14). Expression of ALOX15, AREG, BCL2A1, BCL2L1, CA1, COX7B, ECHDC3, IL18R1, IRS2, KCNE1, MMP9, MYL4 and TREML4 were updated by RTPCR. Only KCNE1 expression decreased in the LVEF ≤ 40% group (p = 0.007). A positive correlation was found between KCNE1 and ejection fraction (r = 0.557; p = 0.001). There was a 12.25-fold risk (95% CI: 1.33 - 113.06; p = 0.027) of LV dysfunction for patients with lower expression of KCNE1. KCNE1 expression showed high AUROC (AUROC: 0.811, 95% CI: 0.642-0.979, p = 0.007), indicating KCNE1 expression as a good predictor of cardiac outcomes. Literature analysis showed that miR-499, miR-1, miR-133a, and miR-208b are the miRNAs most associated with the development of ischemic HF. According to miRNet public database, miR-1 is already described as a regulator of KCNE1 expression. Thus, this study suggests that the expression of KCNE1, as well as its regulatory mechanisms such as miR-1, may be related to LVEF levels and, therefore, to the risk of development of post-AMI HF.

Diabetes ,Nanopartículas ,Cloroquina ,Imunidade ,Células mononucleares do sangue periférico - Abstract
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq O Diabetes mellitus tipo 1 (DM1) é uma doença autoimune, caracterizada por hiperglicemia crônica, a qual gera um processo inflamatório que resulta em complicações micro e macrovasculares. O tratamento do DM1 é direcionado para o controle glicêmico através do uso da insulina, entretanto, não tem sido suficiente para controlar ou reduzir o processo inflamatório. Neste sentido, tem surgido terapias adjuvantes associando anti-inflamatórios e nanopartículas (NPs) como estratégia de prevenir e/ou retardar as complicações associadas a esta doença. A Cloroquina (CQ), por possui propriedades anti-inflamatórias torna-se uma das alternativas de tratamento adjuvante para o diabetes. Assim, o objetivo deste estudo foi avaliar o uso da cloroquina, incorporada ou não em nanopartículas de ácido polilático (PLA), em células mononucleares do sangue periférico (PBMC) de pacientes com DM1, afim de observar seu efeito imunomodulador sobre as citocinas IL-1β, IL-12, IFN-γ, TNF-α e IL-10. Foram selecionados 25 indivíduos normoglicêmicos e 25 pacientes com DM1, ambos com idades entre 10 e 16 anos. O controle glicêmico foi avaliado através da hemoglobina glicada (HbA1c) e concentração sérica de glicose. A viabilidade das PBMCs do grupo DM1 foi avaliada pelo teste MTT por exposição a CQ e CQ incorporada as nanopartículas (CQ NPs) em concentrações de 200, 100, 50, 25, 10 e 5 µM. A concentração de CQ de 10µM foi escolhida e os PBMC dos pacientes DM1 foram submetidos a três condições de tratamento: não tratado (NT), tratado com cloroquina (CQ) e tratado com cloroquina incorporada em nanopartículas (CQ NPs). As células foram incubadas por um período de 48 horas e em intervalos de 24 horas as expressões de mRNA das citocinas IL1B, IFNG, TNFA, IL12 e IL10 foram determinadas por quantificação relativa em PCR em tempo real. A expressão de IL1B foi reduzida em células tratadas com CQ em até 48h (p

Antiofídico ,Escorpião (Tityus serrulatus) ,Antiescorpiônico ,Bothrops jararaca - Abstract
Acidentes com animais peçonhentos, principalmente serpentes e escorpiões, são considerados um sério problema de saúde pública. No Brasil, os acidentes ofídicos ocorrem principalmente por serpentes do gênero Bothrops, e os escorpiônicos pela espécie Tityus serrulatus. O tratamento convencional é o uso da soroterapia antipeçonha, que além de apresentar algumas limitações, como difícil acesso em algumas regiões e custo elevado, é capaz de neutralizar apenas as toxinas da peçonha, sendo ineficiente em inibir as reações inflamatórias endógenas. Dentro deste contexto, o estudo tem como objetivo realizar uma análise fitoquímica do suco dos frutos de Hancornia speciosa, bem como avaliar a capacidade do suco de neutralizar os efeitos inflamatórios da peçonha do escorpião Tityus serrulatus e os locais induzidos pela peçonha de Bothrops jararaca. A análise fitoquímica foi realizada através da técnica de cromatografia líquida de alta eficiência acoplada ao espectrômetro de massas (CLAE-DAD-EM/EM). A atividade antiescorpiônica do suco foi avaliada utilizando-se do modelo animal de edema pulmonar agudo induzido pela peçonha do escorpião T serrulatus. Os animais receberam a peçonha por via subcutânea e foram tratados via oral com o suco nas doses de 100 e 200 mg/kg, utilizando-se de protocolos de pré e pós-tratamento. Após 2 horas da administração da peçonha, os animais foram eutanasiados para a coleta dos pulmões, rins e sangue. Com os tecidos dos pulmões tratados foram realizadas as seguintes análises: quantificação de citocinas, concentração de azul de Evans, dosagem da enzima mieloperoxidase (MPO) e porcentagem do peso relativo pulmonar; com os rins, dosagem de nitrito e peroxidação lipídica; e, com o sangue, avaliados parâmetros hematológicos e bioquímicos. Em relação a peçonha botrópica, a capacidade do suco em inibir seus efeitos locais foi avaliada nos modelos de edema de pata, hemorragia, miotoxicidade e dermonecrose. Para tanto, os animais receberam o suco por via oral nas doses de 100 e 200 mg/kg, sendo administrado logo após a peçonha botrópica (pós-tratamento). Através das análises por CLAE-DAD-EM/EM foram identificados 13 compostos, sendo os majoritários identificados como L-bornesitol, ácido quínico, ácido clorogênico e rutina. As observações referentes à inibição dos efeitos antiescorpiônicos demonstraram que o suco de Hancornia speciosa foi capaz de diminuir significativamente alguns importantes parâmetros como a produção das citocinas, a atividade mieloperoxidase, a concentração de azul de Evans no tecido pulmonar, a peroxidação lipídica e a dosagem de nitrito. Em relação aos efeitos botrópicos, o suco foi capaz de diminuir de forma significativa a lesão dermonecrótica, edema, hemorragia e as concentrações das enzimas creatina quinase e lactato desidrogenase. Portanto, é possível concluir que o suco de Hancornia speciosa Gomes apresenta potencial para ser utilizado como adjuvante no tratamento de envenenamentos escorpiônicos e botrópicos. Accidents with venomous animals, mainly snakes and scorpions, are considered a serious public health problem. In Brazil, ophidian accidents are mainly provoked by snakes of the genus Bothrops, and those with scorpions, by the species Tityus serrulatus. The conventional treatment is the use of antivenom serotherapy, which in addition to presenting some limitations, such as difficult access in some regions and high cost, is only able to neutralize the poison toxins, being inefficient in inhibiting the endogenous reactions triggered by their presence. In this context, the aim of this paper was to perform a phytochemical analysis of the fruit juice of Hancornia speciosa and its ability to inhibit the effects of the venom of the scorpion Tityus serrulatus and the snake Bothrops jararaca. The phytochemical analysis was performed using high performance liquid chromatography MS/MS. The antiscorpionic activity of the juice was evaluated using the animal model of acute pulmonary edema induced by the scorpion venom T serrulatus. For this, Swiss mice received venom subcutaneously and were treated orally with juice at doses of 100 and 200 mg / kg, using pre- and post-treatment protocols. Two hours after venom administration, the animals were euthanized to collect lungs, kidneys and blood. The following analyzes were performed with the lungs: cytokine quantification, evans blue concentration, myeloperoxidase enzyme (MPO) dosage and relative lung weight percentage; with the kidneys, nitrite dosage and lipid peroxidation; and with blood, hematological and biochemical parameters were evaluated. Regarding botropic venom, the ability of the juice to inhibit its local effects was evaluated in the models of paw edema, hemorrhage, myotoxicity and dermonecrosis. For this, Swiss mice of both sexes were used. In all models the juice was administered orally at doses of 100 and 200 mg / kg and was administered shortly after the botropic venom (post-treatment protocol). Through HPLC-DAD-MS / MS analyzes 13 compounds were identified, the major ones identified as L-bornesitol, quinic acid, chlorogenic acid and rutin. Observations regarding the inhibition of antiscorpionic effects demonstrated that Hancornia speciosa juice was able to significantly decrease some important parameters such as cytokine production, myeloperoxidase activity, evans blue concentration in lung tissue, lipid peroxidation and nitrite. Regarding the botropic effects, the juice was able to significantly reduce the dermonecrotic lesion, the edematogenic activity, the hemorrhagic activity and the concentrations of the creatine kinase and lactate dehydrogenase enzymes. From the results, it can be concluded that Hancornia speciosa Gomes juice has great potential to be used as adjuvant in the treatment of scorpion and botropic poisonings.

Magnésio ,Crianças ,Exercício ,Sprint ,Suplementação - Abstract
Por participar de reações envolvidas na produção rápida de energia pela via fosfagênica e considerando que em esportes coletivos a performance depende de um adequado suprimento energético durante a realização dos movimentos, em particular nas modalidades coletivas, caracterizados por movimentos de curta duração e alta intensidade, o magnésio surge como elemento de interesse no meio científico. Nesse sentido, a suplementação com magnésio pode se apresentar como estratégia para promover incremento de índices, possibilitando melhorias em diferentes componentes da aptidão física necessários à prática de esportes coletivos. Dessa forma, o objetivo do presente estudo foi verificar o efeito da suplementação com 350mg/dia de óxido de magnésio na capacidade de sprints repetidos de jovens praticantes de vôlei na iniciação esportiva. Participaram do estudo dezoito crianças, de 9 a 14 anos, de ambos os sexos, que foram randomizadas de forma aleatória em dois grupos: o experimental, que recebeu a suplementação, e o controle, que fez uso de placebo por 30 dias. Todos os participantes foram submetidos à coletas sanguíneas para dosagens bioquímicas dos componentes requeridos e teste de capacidade de sprints repetidos no momento pré e pós intervenção. Uma ANOVA de medidas repetidas (tempo x condição) foi utilizada para verificar os efeitos de interação entre os grupos. Os resultados demonstraram que, em jovens com concentrações séricas de magnésio normais, não houve efeito de interação entre os grupos, embora tenha sido observado efeito de tempo para as variáveis de sprint, no grupo experimental. Magnesium appears as an element of interest for scientific community because it’s involved in rapid energy production reactions through phosphagenic pathway. Besides, it’s considered important for collective sports performance since this modality depends on adequate energy supply during the movement, particularly for collective modalities characterized by short duration and high intensity movements. Thus, magnesium supplementation should be a strategy to increase sportive indexes and making different components of physical fitness improvements possible for collective sports. The aim of the present study was to verify the effect of 350mg / day supplementation with oxide magnesium on young volleyball players repeated-sprint ability during sports initiation. Eighteen children, aged 9 to 14 years, both sexes, who were randomized in two groups: the experimental, who received the supplementation, and the control, who ingesed placebo for 30 days took part in the study. All participants were submitted to blood sample collections for required components biochemical dosages and performed repeated sprints-ability test at pre and post intervention moments. Repeated measures ANOVA (time x condition) was used to verify interaction effects between groups. Results showed there was no interaction effect between the groups for subjects with normal serum magnesium concentrations, although non significant time effect for the sprint variables was observed for experimental group.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq A albuminúria é a principal manifestação clínica da lesão glomerular (LG) após o transplante renal (TxR), que pode ser induzida pelo uso de inibidores do mTOR (do inglês, mammalian target of rapamycin) (imTOR). Uma vez que a LG se inicia com a lesão de podócitos, proteínas dessas células encontradas nas vesículas extracelulares urinárias (VEus), como a nefrina e a podocina, são potenciais biomarcadores para a avaliação precoce da LG. Portanto, os objetivos deste estudo foram: avaliar a expressão de nefrina e podocina em VEus de pacientes TxR com ou sem imTOR no esquema terapêutico imunossupressor, por um período de 12 meses, e avaliar o uso dessas proteínas como biomarcadores específicos de LG. Assim, 47 pacientes TxR foram recrutados e distribuídos em dois grupos de acordo com o uso de imTOR (grupos não-imTOR e imTOR). A expressão de nefrina e podocina foi medida aos 3, 6, 9 e 12 meses de pós-TxR. Valores aumentados nas relações nefrina/creatinina e podocina/creatinina urinárias foram encontrados no grupo imTOR [3 (p = 0,004), 6 (p = 0,009) e 9 meses (p = 0,001); e 3 (p = 0,002), 6 (p = 0,030) e 9 meses (p

Expressão de RNAm ,Retinol ,Extensão lesão coronariana ,Doença cardiovascular ,CIENCIAS DA SAUDE::FARMACIA [CNPQ] ,Alfa-tocoferol - Abstract
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) As vitaminas antioxidantes, alfa-tocoferol e o retinol, assim como a expressão de RNAm de possíveis genes candidatos, foram associados ao risco de DCV. Em um estudo realizado anteriormente por nosso grupo de pesquisa foi sugerido que 13 genes são diferentemente expressos em pacientes com síndrome coronariana aguda. Neste trabalho, objetivou-se investigar o perfil sérico destas vitaminas e a expressão de genes candidatos em leucócitos sanguíneos de pacientes de acordo com a extensão da lesão da artéria coronária. Foram selecionados pacientes com doença arterial coronariana (n = 177), idade entre 30 e 74 anos e submetidos a angiografia coronária eletiva. A extensão da lesão coronária foi avaliada pelo índice de Friesinger, o qual foi dividido em três categorias: 0-4, 5-9 e 10-15. Os níveis séricos de alfa-tocoferol e retinol foram determinados por cromatografia líquida de alta performance (HPLC). A expressão de RNAm dos genes ALOX15, AREG, BCL2A1, BCL2L1, CA1, COX7B, ECHDC3, IL18R1, IRS2, KCNE1, MMP9, MYL4 e TREML4 foram analisadas por RT-qPCR. O nível de alfa-tocoferol foi menor no grupo 0-4 em comparação com o grupo 5-9 (p=0,035) e mostrou uma correlação positiva com os genes BCL2A1, COX7B e correlação negativa com o ECHDC3. O RNAm do gene ECHDC3 foi menos expresso enquanto que o RNAm dos genes AREG, BCL2A1, COX7B, IL18R1 e TREML4 foram mais expressos em pacientes do grupo 10-15 comparados ao grupo 0-4 (p

- Abstract
Introduction: Introduction: Low 25-hydroxyvitamin D [25(OH)D] levels occur after kidney transplantation (KTx), and can be associated with increase the risk of graft loss. This longitudinal study aimed to evaluate the vitamin D status and association with biomarkers of the renal graft function after KTx. Methods: this longitudinal study included 42 patients evaluated at baseline, 3 and 6 months after KTx. Biodemographic, clinical, and biochemical parameters such as 25(OH)D and parathyroid hormone (PTH), and biomarkers of renal graft function, such as creatinine, estimated glomerular filtration rate (eGFR), and albumin/creatinine ratio (ACR), were assessed. Sun exposure was also evaluated. Patients were categorized according to their 25(OH)D levels. Results: at baseline, 25(OH)D levels < 30 ng/mL were found in 43 % patients, and 38 % of these patients failed to improve their 25(OH)D levels by 6 months after KTx. Low 25(OH)D levels occurred regardless of sun exposure. Further, 44 % patients developed albuminuria at 6 months. An increased ACR was observed in patients with 25(OH)D levels < 30 ng/mL (p = 0.002) compared to that in patients with 25(OH)D > 30 ng/mL. Additionally, 25(OH)D levels were negatively correlated with ACR at 6 months post-KTx (r = -0.444; p = 0.003). Twelve (28.6 %) patients with 25(OH)D levels < 30 ng/mL showed no eGFR recovery until 6 months after KTx. Conclusion: low vitamin D levels and increased albuminuria were observed at 6 months after KTx, even in a region with high sun exposure. The association between vitamin D status and biomarkers of renal graft function after KTx should be explored in further studies.

- Abstract
Background: The negative effects of type 1 diabetes (T1D) on growth factors of bone metabolism lead to a reduction in bone mineral density. This study aimed to evaluate the association between bone mineral density and insulin-like growth factor 1 (IGF1), insulin-like growth factor 1 receptor (IGF1R) and transforming growth factor beta 1 (TGFB1) expressions in children and adolescents with T1D. Moreover, the influences of age at diagnosis, time since diagnosis, glycaemic control and albuminuria on bone mineral density were investigated., Methods: Eighty-six T1D children/adolescents (T1D group) and ninety normoglycaemic controls (normoglycaemic group) were included. T1D patients were analysed as a whole and also in subsets of patients with good glycaemic control (glycated hemoglobin concentration ≤7.5%) and with poor glycaemic control (glycated hemoglobin concentration >7.5%). Bone mineral density was assessed by dual energy x-ray absorptiometry. Glycaemic control, renal function and bone markers were also assessed. IGF1, IGF1R and TGFB1 expressions were determined in peripheral blood mononuclear cells by real-time polymerase chain reaction., Results: Patients with T1D showed low bone mineral density and poor glycaemic control. Serum total calcium and urinary albumin-to-creatinine ratio were higher in patients with poor glycaemic control compared to those with good glycemic control (p = 0.003 and p = 0.035, respectively). There was a reduction of IGF1, IGF1R and TGFB1 expressions in the T1D patients and in the subset with poor glycaemic control compared to normoglycaemic controls (p < 0.05)., Conclusions: The decreased IGF1, IGF1R and TGFB1 expressions in the T1D patients, who presented with T1D at an early age, had been diagnosed with T1D for a longer time, had poor glycaemic control and albuminuria may contribute to low bone mineral density.
