Cryopreservation of achenes of caju-de-árvore-docerrado (Anacardium othonianum Rizz)

The aim of the present study was to determine the water content limit for the cryopreservation of cajude-árvore-do-Cerrado (Anacardium othonianum Rizz) achenes and assess the effect of the thawing method on their performance. Achenes were dried in silica gel until water contents of 14, 12, 8 and 4% w.b. (wet basis) were reached and then were stored in cryogenic cylinders in direct contact with liquid nitrogen (-196°C) for 20 days; then, the achenes were subjected to slow, fast and microwave thawing. After thawing, the achenes underwent physiological evaluation and vigor tests. The water content limit for the cryopreservation of A. othonianum Rizz achenes was determined to be between 14 and 12% w.b. Water contents of less than 12% reduced the physiological quality and vigor of the achenes. The thawing method used did not affect the viability of the achenes for most features assessed; however, when thawed in a microwave, the achenes exhibited poorer performance, especially those that had 8% water content.Keywords: Preservation, desiccation, cryogeny, liquid nitrogenAfrican Journal of Biotechnology Vol. 12(22), pp. 3537-354

CONSORT compliance in randomized surgical trials assessing the analgesic and anti-inflammatory effectiveness of preoperative drug management of patients undergoing mandibular third molar surgery:a scoping review

Investigate methodological quality of clinical trials in mandibular third molar surgery and its compliance with the consort statement. An electronic search was performed in five journal websites, chose the five scientific journals with the greatest impact factor in oral and maxillofacial surgery according to the SCImago Journal Rank. The compliance of studies with the CONSORT statement was assessed. Also, the risk of bias of each study was evaluated. Twenty-nine studies were included. The average CONSORT compliance score was 25.50 (79.68%). Most studies were performed in the Americas (n = 14, 48.3%) and Asia (n = 10, 34.5%). Parallel-group (n=15, 51.7%) and split-mouth RCTs (n=11, 38%) were the most prevalent study design. An inverse correlation was observed between the year of publication and the number of Scopus citations (p<0.001), time between acceptance and publication (p<0.001), and time between study completion and publication (p=0.040). Understanding the correct use of guidelines, such as the CONSORT statement, is necessary to reduce methodological errors and possible bias, thereby ensuring reliable knowledge dissemination

Association between blood lactate and heart rate variability in type 2 diabetics during resistance exercise / Associação entre o lactato de sangue e a variabilidade da frequência cardíaca em diabéticos do tipo 2 durante o exercício de resistência

Introduction: During exercise, the branchs sympathetic and parasympathetic, central and peripheral mechanisms interact inducing adjustments on of heart rate (HR) responses according to the intensity, which can be changed in the presence of type 2 diabetes mellitus. Those changes may occur during the time after resistance exercise recovery. Objective: To to compare the method of determining the LA by the blood lactate dosage and HRV, RMSSD and SD1 rates, in individuals with DM2. Results and conclusion: The results of our study show that you have more than 30% of 1RM for the GC as well as for the DM2 group, the latter containing more expressive when compared also with as 40 and 50% loads of 1RM. What is a HRV was observed a significant reduction in relation to the rest in the RMSSD and SD1 indices of CG and soon without a GM2 group, showing in both groups a tendency of stabilization after 30% of 1RM and not being possible to find the LA, determined by HRV, in this specific population submitted to an incremental protocol of resisted lower limb exercise

Quality assessment of systematic reviews regarding the effectiveness of zygomatic implants : an overview of systematic reviews

Oral rehabilitation of atrophic maxillae features high complexity, for which there are several therapeutic modalities reported on scientific literature. Zygomatic implant placement is a viable option that features low morbidity and allows immediate prosthetic loading. The purpose of the present study was to determine the methodological quality of systematic reviews that assessed the effectiveness of zygomatic implants placed in atrophic maxillae. Searches were conducted on Medline via Pubmed, LILACS, Dare Cochrane, Scopus, and Sigle via Open Grey up to June 2019. Seven systematic reviews were eligible for Overview and comprised a total of 2313 patients, 4812 zygomatic implants, and a 96,72% success rate. Common surgical complications, in decreasing order, were: maxillary sinusitis, peri-implant mucositis, prosthetic fracture, and infections. Methodological quality was assessed using the AMSTAR 2 tool, which revealed that six systematic reviews showed critically low methodological quality and one review was assessed as of low methodological quality. Zygomatic implants seem to be an adequate option for atrophic maxilla rehabilitation, however, new studies with a higher methodological rigor are needed to provide more reliable results to professionals and patients undergoing this modality of oral rehabilitation

Secreted extracellular vesicle molecular cargo as a novel liquid biopsy diagnostics of central nervous system diseases

Secreted extracellular vesicles (EVs) are heterogeneous cell-derived membranous granules which carry a large diversity of molecules and participate in intercellular communication by transferring these molecules to target cells by endocytosis. In the last decade, EVs role in several pathological conditions, from etiology to disease progression or therapy evasion, has been consolidated, including in central nervous system (CNS)-related disorders. For this review, we performed a systematic search of original works published, reporting the presence of molecular components expressed in the CNS via EVs, which have been purified from plasma, serum or cerebrospinal fluid. Our aim is to provide a list of molecular EV components that have been identified from both nonpathological conditions and the most common CNS-related disorders. We discuss the methods used to isolate and enrich EVs from specific CNS-cells and the relevance of its components in each disease context.This research was funded by the MindGaP-H2020-FETOPEN-2018-2020, Grant agreement ID: 829040.

Análise econométrica da previsão do fluxo de passageiros no terminal aeroviário após privatização - Estudo de caso do aeroporto de Fortaleza/ Econometric analysis of the forecast of passenger flow at the air terminal after privatization - Fortaleza airport case study

O desenvolvimento de um terminal aeroportuário deve ser essencialmente orientado pelas demandas projetadas nos seus diversos segmentos (passageiros domésticos, internacionais, carga paga). O presente estudo visa desenvolver uma previsão da demanda de passageiros no aeroporto de Fortaleza, que foi privatizado pelo governo federal. A gerência da nova concessionária propiciou novas conexões internacionais, a expansão aeroportuária, o hub aéreo, em parte o incentivo ao turismo na cidade de Fortaleza e no estado do Ceará. Inicialmente apresenta-se uma breve revisão de literatura, que conta com modelos de regressão linear. Sendo usada a mesma ferramenta da econometria, a regressão linear, com o intuito de fazer uma análise de demanda futura. Utilizando-se uma série de dados observacionais econômicos do estado e do país, a movimentação aeroportuária e outras variáveis inerentes à aviação civil. Foi possível fazer uma estimativa para os próximos anos, levando-se em conta o atual cenário econômico brasileiro. Também foram reportados alguns fatores que poderiam ter influenciado de forma contraditória a literatura em algumas das variáveis independentes na modelagem tanto de forma positiva quanto negativa nessa estimativa. Por fim com os resultados obtidos do estudo, foram realizadas comparações da previsão de demanda com as estimativas do relatório de estudos de mercado, para cinco anos a partir do ano em análise e também ao final da concessão. Em que foi observado uma aproximação para a estimativa após os cinco primeiros anos da concessão, enquanto foi notória uma expressiva diferença para a tendência de fluxo ao fim da concessão.

Can intraoperative electrocorticography patterns predict surgical outcome in patients with temporal lobe epilepsy secondary to unilateral mesial temporal sclerosis?

Introduction: Intraoperative electrocorticography (ECoG) can be performed in cases of temporal lobe epilepsy due to hippocampal sclerosis (TLE-HS). However, its significance and correlation with surgical outcome are still controversial.Objectives: To analyze the electrophysiological characteristics of temporal lobe structures during ECoG of patients with TLE-HS, with emphasis on the comparison between pre- and post-resection recordings and surgical outcome.Patients and methods: Seventeen patients with refractory TLE-HS submitted to corticoamigdalohipocampectomy were included in the study. Clinical variables included age at the onset, duration of epilepsy and seizure outcome. the postoperative follow-up ranged from 24 to 36 months. According to outcome subjects were divided in two subgroups: (A) individuals free of seizures (Engel 1A), and (B) individuals not-free of seizures (Engel 1B-IV). Four patterns of ECoG findings were identified: isolated discharges; high frequency spikes (HFS); continuous discharges; combination of isolated discharges and HFS. According to predominant topography ECoG was classified as mediobasal, lateral (or neocortical), mediobasal and lateral.Results: the progressive removal of the temporal pole and the hippocampus was associated with significant decrease of neocortical spikes. No correlation between clinical variables and seizure outcome was observed. Patients who only had isolated spikes on intraoperative ECoG presented a statistical trend for excellent surgical control. Patients who presented temporal pole blurring on MRI also had better post-surgical seizure outcome.Conclusions: This study showed that out of diverse clinical and laboratory variables, only isolated discharges on intraoperative ECoG and temporal pole blurring on MRI predicted excellent post-surgicat seizure outcome. However, other studies with larger number of patients are stilt necessary to confirm these findings. (C) 2006 British Epilepsy Association. Published by Elsevier B.V.

FIRE EFECT ON THE SEASONAL FOREST STRUCTURE IN THE CERRADO BIOME

There are few studies on the effects of fire on the seasonal semideciduous forest of the Cerrado region. This study aimed to assess the effect of fire on Semideciduous forest fragments located in the Altamiro Moura Pacheco State Park (AMPSP). The study area is located in the central state of Goiás. A total of 10 plots (50 x 20 m; 1,000 m2) were drawn in the remaining forests seeking to portray two areas: area which underwent forest fire (burned area; B) and unburned area (unburned; UB). A total of 771 individuals with DBH (≥ 5 cm) were identified. A total of 303 individuals were recorded in the burned area (B), comprising 28 families, 41 genera and 47 species, while the unburned area (UB) had 468 individuals comprising 25 families, 43 genera and 50 species. The species Anadenanthera colubrina (Vell.) Brenan, Emmotum nitens (Benth.), Zanthoxylum rhoifolium Lam, Tapirira guianensis Aubl., Myracrodruon urundeuva Allemão and Luehea candicans Mart. had the highest Importance Value Index (IVI) values and occur in both areas. The percentage of dead trees differed between the areas, where the burned area had a mortality of 12.69% and the unburned area of 7.29% in regards to the number of individuals. Density per plot was the only parameter that differed between the areas, where the burned area (B) had the lowest values. The fire affected all diameter classes, demonstrating the fragility of this vegetation type in regards to fire. The fire had a greater effect on trees in the smaller diameter classes, reducing the frequency of individuals in the burned area and changing height distribution, which may have favored the establishment of lianas and invasive species.
