Formulación de galletas fortificadas por sustitución parcial de harina de moringa y suero lácteo / Formulation of fortified cookies by partial substitution of moringa flour and whey

El suero lácteo y la moringa poseen alto valor nutricional; sin embargo, su uso en la elaboración de productos alimenticios es una alternativa viable pero poco utilizada. Objetivo. Elaborar una galleta fortificada por sustitución parcial de harina de moringa (HM) y polvo de suero lácteo (PSL). Materiales y métodos. Durante septiembre-diciembre 2021, se desarrollaron cuatro formulaciones con sustitución parcial de harina de trigo por HM y PSL (F0=100:0:0; F1=90:5:5; F2=80:10:10; F3=70:15:15). La aceptación del producto se determinó mediante una evaluación sensorial considerando los atributos sabor, olor, color, textura y aceptación general. Se realizó el análisis químico proximal a la HM, al PSL, a la formulación de mayor aceptación y a F0. Se compararon los distintos parámetros químico proximales y de aceptación mediante una anova de una vía, seguido de una prueba de comparación de medias de Tukey (p<0,05). Resultados. Conforme se incrementa el porcentaje de sustitución de harina de trigo por HM y PSL se obtiene menor aceptación de las galletas, siendo F1 la más aceptada. F1 registró un contenido proteico de 6,90±0,04%, significativamente mayor al observado en F0. Conclusiones. La buena aceptabilidad de F1 indica que la sustitución parcial por HM y PSL no influyen en su aceptación; además, F1 mostró un enriquecimiento de proteinas, lípidos y cenizas, así como contenido adecuado de humedad y carbohidratos(AU)

Introduction. Whey and moringa have high nutritional value; however, their use in the production of food products is a viable but rarely used alternative. Objective. To make a biscuit fortified by partial substitution of moringa flour (MF) and whey powder (WP). Materials and methods. During September-December 2021, four formulations were developed with different degrees of partial substitution of wheat flour for MF and WP (F0=100:0:0; F1=90:5:5; F2=80:10:10; F3=70:15:15). The acceptance of the product was determined through a sensory evaluation considering the attributes taste, odor, color, texture and general acceptance. A proximal chemical analysis was performed on the MF, WP, the most widely accepted formulation and F0. Proximal chemical parameters and acceptance attributes were compared using a one-way anova, followed by a Tukey mean comparison test (p<0.05). Results. As the percentage of substitution of wheat flour by MF and WP increases less acceptance of the biscuits is obtained, with F1 as the most accepted formulation. F1 registered a protein content of 6.90±0.04%, significantly higher than that observed in F0. Conclusions: The good acceptability of F1 indicates that the partial substitution of wheat flour for MF and WP do not influence its acceptance; in addition, F1, showed an enrichment of protein, lipid and ash, as well as adequate moisture and carbohydrate content(AU)

Cytopathological characterization of ascites for the diagnosis of serous ovarian carcinoma / 中华肿瘤杂志

Objective: To investigate the cytomorphological and immunocytochemical features of tumor cells in the ascites of ovarian plasmacytoma (SOC). Methods: Specimens of serous cavity effusions were collected from 61 tumor patients admitted to the Affiliated Wuxi People's Hospital of Nanjing Medical University from January 2015 to July 2021, including ascites from 32 SOC, 10 gastrointestinal adenocarcinomas, 5 pancreatic ductal adenocarcinomas, 6 lung adenocarcinomas, 4 benign mesothelial hyperplasia and 1 malignant mesothelioma patients, pleural effusions from 2 malignant mesothelioma patients and pericardial effusion from 1 malignant mesothelioma. Serous cavity effusion samples of all patients were collected, conventional smears were made through centrifugation, and cell paraffin blocks were made through centrifugation of remaining effusion samples. Conventional HE staining and immunocytochemical staining were applied to observe and summarize cytomorphological characteristics and immunocytochemical characteristics. The levels of serum tumor markers carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) were detected. Results: Of the 32 SOC patients, 5 had low-grade serous ovarian carcinoma (LGSOC) and 27 had high-grade serous ovarian carcinoma (HGSOC). 29 (90.6%) SOC patients had elevated serum CA125, but the difference was not statistically significant between them and patients with non-ovarian primary lesions included in the study (P>0.05); The serum CEA was positive in 9 patients with gastrointestinal adenocarcinoma and 5 patients with lung adenocarcinoma, and the positive rate was higher than that in SOC patients (P<0.001); The serum CA19-9 was positive in 5 patients with gastrointestinal adenocarcinoma and 5 patients with pancreatic ductal adenocarcinoma, and the positive rate was higher than that in SOC patients (P<0.05). The serum CA125, CEA and CA19-9 were within the normal range in 4 patients with benign mesothelial hyperplasia. LGSOC tumor cells were less heterogeneous and aggregated into small clusters or papillary pattern, and psammoma bodies could be observed in some LGSOC cases. The background cells were fewer and lymphocytes were predominant; the papillary structure was more obvious after making cell wax blocks. HGSOC tumor cells were highly heterogeneous, with significantly enlarged nuclei and varying sizes, which could be more than 3-fold different, and nucleoli and nuclear schizophrenia could be observed in some cases; tumor cells were mostly clustered into nested clusters, papillae and prune shapes; there were more background cells, mainly histiocytes. Immunocytochemical staining showed that AE1/AE3, CK7, PAX-8, CA125, and WT1 were diffusely positively expressed in 32 SOC cases. P53 was focally positive in all 5 LGSOCs, diffusely positive in 23 HGSOCs, and negative in the other 4 HGSOCs. Most of adenocarcinomas of the gastrointestinal tract and lung had a history of surgery, and tumor cells of pancreatic ductal adenocarcinoma tend to form small cell nests. Immunocytochemistry can assist in the differential diagnosis of mesothelial-derived lesions with characteristic "open window" phenomenon. Conclusion: Combining the clinical manifestations of the patient, the morphological characteristics of the cells in the smear and cell block of the ascites can provide important clues for the diagnosis of SOC, and the immunocytochemical tests can further improve the accuracy of the diagnosis.

Variations in nutritional profile of honey produced by various species of genus Apis / Variações no perfil nutricional do mel produzido por várias espécies do gênero Apis

Abstract The medicinal attributes of honey appears to overshadow its importance as a functional food. Consequently, several literatures are rife with ancient uses of honey as complementary and alternative medicine, with relevance to modern day health care, supported by evidence-based clinical data, with little attention given to honey's nutritional functions. The moisture contents of honey extracted from University of Veterinary and Animal Sciences, Lahore honey bee farm was 12.19% while that of natural source was 9.03 ± 1.63%. Similarly, ash and protein contents of farmed honey recorded were 0.37% and 5.22%, respectively. Whereas ash and protein contents of natural honey were 1.70 ± 1.98% and 6.10 ± 0.79%. Likewise fat, dietary fiber and carbohydrates contents of farmed source documented were 0.14%, 1.99% and 62.26% respectively. Although fat, dietary fiber and carbohydrates contents of honey taken from natural resource were 0.54 ± 0.28%, 2.76 ± 1.07% and 55.32 ± 2.91% respectively. Glucose and fructose contents of honey taken out from honeybee farm were 27% and 34% but natural source were 22.50 ± 2.12% and 28.50 ± 3.54%. Glucose and fructose contents of honey taken out from honeybee farm were 27% and 34% but natural source were 22.50 ± 2.12% and 28.50 ± 3.54%. Similarly, sucrose and maltose contents of farmed honey were 2.5% and 12% while in natural honey were 1.35 ± 0.49% and 8.00 ± 1.41% respectively. The present study indicates that such as moisture, carbohydrates, sucrose and maltose contents were higher farmed honey as compared to the natural honey. In our recommendation natural honey is better than farmed honey.

Resumo Os atributos medicinais do mel parecem ofuscar sua importância como alimento funcional. Consequentemente, várias literaturas estão repletas de usos antigos do mel como medicina complementar e alternativa, com relevância para os cuidados de saúde modernos, apoiados por dados clínicos baseados em evidências, com pouca atenção dada às funções nutricionais do mel. O teor de umidade do mel extraído da Universidade de Veterinária e Ciências Animais, fazenda de abelhas de Lahore, foi de 12,19%, enquanto o de fonte natural foi de 9,03 ± 1,63%. Da mesma forma, os teores de cinzas e proteínas do mel cultivado foram de 0,37% e 5,22%, respectivamente. Já os teores de cinzas e proteínas do mel natural foram de 1,70 ± 1,98% e 6,10 ± 0,79%. Da mesma forma, os teores de gordura, fibra dietética e carboidratos de origem cultivada documentados foram de 0,14%, 1,99% e 62,26%, respectivamente. Embora os teores de gordura, fibra alimentar e carboidratos do mel retirado dos recursos naturais fossem de 0,54 ± 0,28%, 2,76 ± 1,07% e 55,32 ± 2,91%, respectivamente. Os conteúdos de glicose e frutose do mel retirado da fazenda de abelhas foram de 27% e 34%, mas a fonte natural foi de 22,50 ± 2,12% e 28,50 ± 3,54%. Os conteúdos de glicose e frutose do mel retirado da fazenda de abelhas foram de 27% e 34%, mas a fonte natural foi de 22,50 ± 2,12% e 28,50 ± 3,54%. Da mesma forma, os teores de sacarose e maltose no mel cultivado foram de 2,5% e 12%, enquanto no mel natural foram de 1,35 ± 0,49% e 8,00 ± 1,41%, respectivamente. O presente estudo indica que os teores de umidade, carboidratos, sacarose e maltose foram maiores no mel cultivado em comparação ao mel natural. Em nossa recomendação, o mel natural é melhor que o mel de cultivo.

Clinical characteristics of hypersensitivity pneumonitis: non-fibrotic and fibrotic subtypes / 中华医学杂志(英文版)

BACKGROUND@#The presence of fibrosis is a criterion for subtype classification in the newly updated hypersensitivity pneumonitis (HP) guidelines. The present study aimed to summarize differences in clinical characteristics and prognosis of non-fibrotic hypersensitivity pneumonitis (NFHP) and fibrotic hypersensitivity pneumonitis (FHP) and explore factors associated with the presence of fibrosis.@*METHODS@#In this prospective cohort study, patients diagnosed with HP through a multidisciplinary discussion were enrolled. Collected data included demographic and clinical characteristics, laboratory findings, and radiologic and histopathological features. Logistic regression analyses were performed to explore factors related to the presence of fibrosis.@*RESULTS@#A total of 202 patients with HP were enrolled, including 87 (43.1%) NFHP patients and 115 (56.9%) FHP patients. Patients with FHP were older and more frequently presented with dyspnea, crackles, and digital clubbing than patients with NFHP. Serum levels of carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 153, gastrin-releasing peptide precursor, squamous cell carcinoma antigen, and antigen cytokeratin 21-1, and count of bronchoalveolar lavage (BAL) eosinophils were higher in the FHP group than in the NFHP group. BAL lymphocytosis was present in both groups, but less pronounced in the FHP group. Multivariable regression analyses revealed that older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors for the development of FHP. Twelve patients developed adverse outcomes, with a median survival time of 12.5 months, all of whom had FHP.@*CONCLUSIONS@#Older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors associated with the development of FHP. Prognosis of patients with NFHP was better than that of patients with FHP. These results may provide insights into the mechanisms of fibrosis in HP.

OBJECTIVE@#To investigate the effect of gastric antrum ultrasonography in evaluating gastric emptying after oral administration of 300 mL carbohydrates two hours before cesarean section, and to analyze the risk factors of gastric emptying in pregnant women.@*METHODS@#From August 2020 to February 2021, a total of 80 patients, aged 22-43 years, body mass index (BMI) < 35 kg/m2, gestational age≥36 weeks, falling into American Society of Anesthesiologists (ASA) physical status Ⅰ or Ⅱ, scheduled for cesarean sections in Peking University International Hospital were recruited and divided into two groups: the intervention group (n=40)and the control group (n=40). In the intervention group, solid food was restricted after 22:00, the patients were required to take 300 mL carbohydrates two hours before cesarean section. In the control group, solid food and liquid intake were restricted after 22:00 the night before surgery. All the patients received assessment of preoperative feeling of thirst and starvation with visual analogue scale (VAS). The cross-sectional area (CSA)of gastric antrum was measured in supine position and right supine position before anesthesia, the gastric volume (GV)and the gastric volume/weight(GV/W)of the two groups was further calculated. Perlas A semi-quantitative grading assessments were performed in each patient. The blood pressure and heart rate were recorded at admission(T0), 5 minutes after anesthesia (T1), immediately after fetal delivery (T2) and at the end of the surgery (T3). The occurrence of nausea and vomiting during the operation and 24 hours after the operation were recorded.@*RESULTS@#One case in each group was excluded because the antrum was not clearly identified during the ultrasound assessments. In the semi-sitting position, the CSA was (5.07±1.73) cm2 in the intervention group vs. (5.24±1.96) cm2 in the control group, respectively; in the right lateral decubitus position, CSA was (7.32±2.17) cm2 in the intervention group vs. (7.25±2.24) cm2 in the control group, GV was (91.74±32.34) mL vs. (90.07±31.68) mL, GV/W was (1.27±0.40) mL/kg vs. (1.22±0.41) mL/kg, respectively; all the above showed no significant difference between the two groups (P > 0.05). Perlas A semi-quantitative grading showed 0 in 20 patients (51.3%), 1 in 16 (41%), 2 in 3 (7.7%)in the intervention group and 0 in 22 (56.4%), 1 in 15 (38.5%), 2 in 2 (5.1%)in the control group, the proportion of Perlas A semi-quantitative grading showed no significant difference between the two groups (P > 0.05). For the patients with Perlas A semi-quantitative grade 2 (3 cases in the intervention group and 2 cases in the control group), metoclopramide 0.2 mg/kg was intravenously injected before anesthesia. No aspiration case was observed in this study. The intervention group was endured less thirst and hunger (P < 0.05). There was no significant difference in blood pressure and heart rate between the two groups at each time point (P > 0.05). There was no significant difference in the incidence of intraoperative hypotension between the two groups (P > 0.05). There was no significant difference in the incidence of nausea intraoperatively and postoperatively between the two groups (P > 0.05).@*CONCLUSION@#Ultrasonography of gastric antrum can provide objective basis for evaluating gastric emptying of pregnant women perioperatively. 300 mL carbohydrates intake two hours before surgery, which does not increase GV and the risk of reflux aspiration, and is helpful in minimizing disturbance to the patient's physiological status, therefore leading to better clinical outcome.

Biopelícula cariogénica de Streptococcus mutans y efecto hemostático de ácido tánico en la hemorragia post-exodoncia / Streptococcus mutans cariogenic biofilm and hemostatic effect of tannic acid in post-extraction hemorrhage

La caries dental y la placa dental se encuentran entre las enfermedades más comunes en todo el mundo y son causadas por una mezcla de microorganismos y restos de alimentos. Tipos específicos de bacterias productoras de ácido, especialmente Streptococcus mutans, colonizan la superficie dental y causan daño a la estructura dental dura en presencia de carbohidratos fermentables, por ejemplo, sacarosa y fructosa. Por otro lado, el sangrado posterior a la extracción es una complicación reconocida y frecuente en la práctica dental, que se define como la pérdida de sangre que continúa más allá de las 8 a 12 horas después de la exodoncia. Existe una amplia gama de técnicas sugeridas y sustancias para el tratamiento del sangrado post-extracción, que incluyen intervenciones dirigidas tanto a causas locales como sistémicas. El ácido tánico es una de las sustancias astringente que precipitan proteínas, pero no penetran en las células, por lo que inciden solo en la capa superficial. Su objetivo se enfoca a robustecer la superficie para acrecentar su resistencia mecánica y reducir la exudación. El objetivo de este estudio fue determinar la presencia de S. mutans en las biopelículas dentales y al mismo tiempo evaluar la actividad del ácido tánico como inhibidor del sangrado profuso en las extracciones dentales. S. mutans se aisló en el 92,5% de los pacientes evaluados. Los tiempos de hemostasia post-exodoncia fue significativamente menor en el grupo de pacientes a los que se les aplicó el ácido tánico en comparación a los que no se les aplicó(AU)

Tooth decay and dental plaque are among the most common diseases worldwide and are caused by a mix of microorganisms and food debris. Specific types of acid-producing bacteria, especially Streptococcus mutans, colonize the tooth surface and cause damage to hard tooth structure in the presence of fermentable carbohydrates, for example, sucrose and fructose. On the other hand, post-extraction bleeding is a recognized and frequent complication in dental practice, defined as blood loss that continues beyond 8 to 12 hours after extraction. There is a wide range of suggested techniques and substances for the treatment of post-extraction bleeding, including interventions targeting both local and systemic causes. Tannic acid is one of the astringent substances that precipitate proteins, but does not penetrate the cells, so it affects only the superficial layer. Its objective is focused on strengthening the surface to increase its mechanical resistance and reduce exudation. The objective of this study was to determine the presence of S. mutans in dental biofilms and at the same time to evaluate the activity of tannic acid as an inhibitor of profuse bleeding in dental extractions. S. mutans was isolated in 92.5% of the patients evaluated. Post-extraction hemostasis times were significantly shorter in the group of patients who received tannic acid compared to those who did not(AU)

Vitamin D concentrations and their relationship with iron parameters in patients with chronic kidney disease / Concentrações de vitamina D e sua relação com parâmetros de ferro em pacientes com doença renal crônica

ABSTRACT Objective To investigate the relationship between calcidiol (25(OH)D3) concentrations and iron parameters in patients with chronic kidney disease. Methods This is a cross-sectional, descriptive, and quantitative study. The sample consisted of 86 adult patients of both sexes undergoing dialysis. 25(OH)D3 concentrations were determined by chemiluminescence; food consumption was assessed using 24-hour recalls, and the serum levels of hemoglobin, iron, ferritin, and transferrin saturation were assessed. Data analysis was performed using the program Stata, with a significance level of p<0.05. Results The results pointed to 25(OH)D3 concentrations compatible with sufficiency, iron levels consistent with normality, and ferritin and transferrin saturation above the reference values. The consumption of carbohydrates and lipids was higher in females. There was no relationship between the adequacy of 25(OH)D3 and the presence of anemia and iron parameters. Conclusion Considering that the mean serum levels of iron and 25(OH)D3 were adequate, it is suggested that resistance to erythropoietin and the inflammatory process may have contributed to the percentage of anemic individuals found in the study.

RESUMO Objetivo Investigar a relação entre as concentrações de calcidiol (25(OH)D3) e os parâmetros de ferro em pacientes com doença renal crônica. Métodos É um estudo transversal, descritivo e quantitativo. A amostra foi composta por 86 pacientes, adultos, de ambos os sexos, em terapia dialítica. As concentrações de 25(OH)D3 foram determinadas pelo método de quimioluminescência; o consumo alimentar foi avaliado pela aplicação de Recordatórios de 24 horas e foram avaliados os níveis séricos de hemoglobina, ferro, ferritina e saturação de transferrina. A análise dos dados foi realizada no programa Stata, com nível de significância p<0.05. Resultados Os resultados apontaram para concentrações de 25(OH)D3 compatíveis com suficiência, níveis de ferro compatíveis com a normalidade e ferritina e saturação de transferrina superiores à referência. O consumo de carboidratos e lipídios foi superior no sexo feminino. Não foi verificada relação entre a adequação de 25(OH)D3 e a presença de anemia e parâmetros de ferro. Conclusão Tendo em vista que os níveis médios séricos de ferro e 25(OH)D3 estavam adequados, sugere-se que a resistência à eritropoietina e o processo inflamatório podem ter contribuído para o percentual de anêmicos constatado no estudo.

Carbohydrate-based gold nanoparticles as colorimetric sensor for cysteine

Background@#Gold nanoparticles have been studied extensively for their potential application in the detection of important analytes. Their relative ease of synthesis through numerous procedures makes possible their implementation in a variety of assays. Cysteine (cys), a thiol-containing amino acid implicated in numerous pathologies such as obstructive sleep apnea (OSA), has been routinely detected through expensive fluorometric assay kits. @*Objectives@#As such, this study aimed to develop a carbohydrate-based gold nanoparticle colorimetric assay for the convenient and straightforward detection of cys. @*Methodology@#Carbohydrate-based gold nanoparticles (c-AuNPs) were synthesized following a microwaveassisted procedure. The as-prepared c-AuNPs were used to detect cys by plotting the ratio of the absorbances of the aggregated and dispersed gold nanoparticles against the concentration of cys. @*Results@#The c-AuNP solutions were able to detect cys in the micromolar range, with the glucose-based AuNPs (glc-AuNPs) showing the widest linear range (16.7 μm to 167 μm), and the fructose-based gold nanoparticles (frc-AuNPs) exhibiting the lowest detection limit (9.0 μm) for cys. Aside from being able to detect cys, the c-AuNPs were also responsive to tyr and lys.@*Conclusion@#This study demonstrates that carbohydrate-based gold nanoparticles prepared following a microwave-assisted procedure using sugars as reducing agents and capping agents can be used successfully in the detection of cysteine.

Chemical synthesis of a synthetically useful L-galactosaminuronic acid building block / 中国天然药物

Most bacterial cell surface glycans are structurally unique, and have been considered as ideal target molecules for the developments of detection and diagnosis techniques, as well as vaccines. Chemical synthesis has been a promising approach to prepare well-defined oligosaccharides, facilitating the structure-activity relationship exploration and biomedical applications of bacterial glycans. L-Galactosaminuronic acid is a rare sugar that has been only found in cell surface glycans of gram-negative bacteria. Here, an orthogonally protected L-galactosaminuronic acid building block was designed and chemically synthesized. A synthetic strategy based on glycal addition and TEMPO/BAIB-mediated C6 oxidation served well for the transformation of commercial L-galactose to the corresponding L-galactosaminuronic acid. Notably, the C6 oxidation of the allyl glycoside was more efficient than that of the selenoglycoside. In addition, a balance between the formation of allyl glycoside and the recovery of selenoglycoside was essential to improve efficiency of the NIS/TfOH-catalyzed allylation. This synthetically useful L-galactosaminuronic acid building block will provide a basis for the syntheses of complex bacterial glycans.

The application of carbohydrate binding module-Thermobifida fusca cutinase fusion protein in polyethylene terephthalate degradation / 生物工程学报

With the development of global economy, the dramatically increased production of polyethylene terephthalate (PET) plastics has led to a remarkably increased amount of plastic waste. PET waste can be treated by landfill, incineration, or biodegradation. While landfilling and incineration may cause secondary pollution, biodegradation has since received increased attentions due to its environmental friendliness. Recent studies have indicated that the carbohydrate binding module (CBM) can effectively enhance the binding of PET degrading enzymes to PET, and consequently increasing PET degradation rate. Here we constructed a fusion protein BaCBM2-Tfuc containing the BaCBM2 from Bacillus anthraci and the cutinase Tfuc from Thermobifida fusca, by megaprimer PCR of whole plasmids (MEGAWHOP). Notabaly, the PET film degradation efficiency (at 60 ℃) of BaCBM2-Tfuc was 2.8 times that of Tfuc. This study may provide technical support for constructing fusion proteins capable of efficiently degrading PET.

Anafilaxia a alfa-gal: um relato de caso paraibano / Alpha-gal anaphylaxis: a case report from Paraíba, Brazil

O presente relato apresenta um caso de anafilaxia tardia ao carboidrato alfa-gal em um adolescente da cidade de Belém, na Paraíba, Brasil. O paciente desenvolveu reação tardia à ingesta de carne e vísceras de animais. Ele mora em fazenda e tem contato próximo com animais potencialmente contaminados por carrapatos. Essa causa de reação alérgica é nova, e estudos começaram a atribuí-la a casos antes ditos idiopáticos. A anafilaxia é uma reação potencialmente fatal, que deve ser prontamente diagnosticada e tratada. Sendo assim, a descoberta de seu fator desencadeante é um dos principais itens que direcionam o tratamento. No Brasil, nenhum caso de anafilaxia por alfa-gal foi antes descrito na literatura local.

This report presents a case of late anaphylaxis to alpha-gal carbohydrate in a teenager living in the city of Belém, Paraíba, Brazil. The patient developed a late reaction to eating meat and offal of animals; he lives on a farm and has close contact with animals potentially contaminated by ticks. This cause of allergic reaction is new, and studies have started to attribute it to cases previously said to be idiopathic. Anaphylaxis is a potentially fatal reaction that must be promptly diagnosed and treated. Thus, the discovery of its triggering factor is one of the main items that guide treatment. In Brazil, no case of alpha-gal anaphylaxis had been described in the local literature.

Niveles séricos de interleucina-6 en pacientes con diabetes tipo 2 y su correlación con el perfil lipídico / Serum levels of interleukin-6 in patients with type 2 diabetes and its correlation with the lipid profile

La diabetes mellitus es una enfermedad metabólica caracterizada por hiperglucemia, a consecuencia de defectos en la producción, secreción y/o acción de la insulina, produciendo alteraciones en el metabolismo de los hidratos de carbono, lípidos y proteínas; asociado a un proceso inflamatorio crónica en un plazo variable, que provocara lesiones macro y microvasculares. Objetivo: Evaluar los niveles séricos de interleucina-6 (IL-6) en pacientes diabéticos tipo 2 y su correlación con el perfil lipídico. Métodos: Se realizó estudio descriptivo analítico y transversal, comprendido por 60 adultos de ambos sexos entre 30 a 60 años, con diabetes mellitus tipo 2 que acudieron a consulta de Endocrinología del Hospital Militar Universitario Dr. Carlos Arvelo. Se les determino glucemia basal, interleucina-6, perfil lipídico, resultados relacionados con parámetros antropométricos, composición corporal, la edad y tiempo de evolución de la diabetes. Resultados: La edad promedio de 51,60 años ± 6,51, donde el 71,6% correspondieron al sexo femenino y el 28,3% al masculino, tiempo de evolución de la diabetes entre 1 mes y 37 años, con un promedio de 10,97 años. Se presentó correlación positiva baja y estadísticamente significativa entre interleucina 6 y los parámetros de triglicéridos, VLDL y no-HDL Conclusión: Se encontró valores elevados de IL-6 en todos los pacientes diabéticos tipo 2, así como una correlación positiva entre IL-6 y las lipoproteínas ricas en triglicéridos. Esto respalda la idea de que la hipertrigliceridemia puede causar cambios inflamatorios en pacientes diabéticos y esto elevaría el riesgo cardiovascular de estos pacientes(AU)

Hormônio do crescimento versus treinamento de força: alterações nas estruturas colágenas, lipídicas e glicídicas / Growth hormone (gh) versus strength training: changes in collagen, lipid and glucidic structures

O objetivo deste estudo foi avaliar o efeito da aplicação de hormônio do crescimento (Growth Hormone - GH) e treinamento de força (TF) na composição do tecido ósseo de ratos Wistar a partir da Espectroscopia Raman. 40 ratos machos foram distribuídos de forma aleatória em quatro grupos: controle (C [n=10]), controle a aplicação de GH (GHC [n=10]), treinamento de força (T [n=10]) e treinamento de força e aplicação de GH (GHT [n=10]). O treinamento foi composto por quatro séries de 10 saltos aquáticos, realizados três vezes por semana, com sobrecarga correspondente a 50% do peso corpóreo e duração de quatro semanas. O GH foi aplicado na dose de 0,2 UI/Kg em cada animal, três vezes por semana e em dias alternados. Ao final do experimento, os animais foram eutanasiados e coletados os fêmures direitos para realização da análise da composição óssea. A espectroscopia Raman (ER) foi utilizada para observar os seguintes compostos a partir de suas respectivas bandas: colágeno e fosfolipídio (1445 cm-1), colesterol (548 cm-1), glicerol (607 cm-1), glicose (913 cm-1), Pico de carboidrato (931 cm-1 ) e prolina (918 cm-1 ). Para a análise estatística, foram realizados os testes de normalidade de Shapiro-Wilk e análise de variâncias ANOVA one-way, seguida pelo pós-teste de Tukey. Os resultados revelaram aumento nas concentrações de colágeno e fosfolipidio, colesterol, glicerol, glicose, pico de carboidrato e prolina em todos os grupos experimentais, associados ou não à realização do ST e/ou aplicação de GH. Porém, somente o grupo T diferiu significativamente do grupo C (p<0,05). Conclui-se que todas intervenções puderam promover ganho no tecido ósseo, porém, somente o grupo T demonstrou diferença significativa nos compostos minerais analisados. (AU)

The objective of this study was to evaluate the effect of the application of growth hormone (GH) and strength training (TF) on the bone tissue composition of Wistar rats using Raman Spectroscopy. 40 male rats were randomly assigned to four groups: control (C [n = 10]), control the application of GH (GHC [n = 10]), strength training (T [n = 10]) and training of strength and application of GH (GHT [n = 10]). The training consisted of four series of 10 water jumps, performed three times a week, with an overload corresponding to 50% of body weight and lasting four weeks. GH was applied at a dose of 0.2 IU / kg to each animal, three times a week and on alternate days. After four weeks, the animals were euthanized and the right femurs were collected to carry out the analysis of the bone composition. Raman spectroscopy (ER) was used to observe the following compounds from their respective bands: collagen and phospholipid (1445 cm-1), cholesterol (548 cm-1), glycerol (607 cm-1), glucose (913 cm-1), Peak carbohydrate (931 cm-1), proline (918 cm-1). For statistical analysis, the Shapiro-Wilk normality tests and ANOVA One-Way analysis of variances were performed, followed by the Tukey post-test. The results revealed an increase in the concentrations of collagen and phospholipid, cholesterol, glycerol, glucose, peak carbohydrate and proline in all experimental groups, associated or not with the performance of ST and / or application of GH. However, only group T differed significantly from group C (p <0.05). It was concluded that all intervention could promote gain in bone tissue, however, only the T group showed a significant difference in the analyzed mineral compounds. (AU)

Cognitive restraint directed at carbohydrates in individuals on low-carb diet with binge eating: the role of guilt about food cravings / Restrição cognitiva direcionada aos carboidratos em indivíduos praticantes de dieta low carb com compulsão alimentar: o envolvimento da culpa pelos desejos por comida

ABSTRACT Objective To evaluate whether the carbohydrate-restricted diet leads to higher levels of food cravings in individuals with binge eating. Methods A total of 146 individuals with binge eating participated in the Low-Carb Diet Group (n=48) and Control Group (n=98). The Binge Eating Scale, Hay's questionnaire, Food Cravings Questionnaire - Trait and State, Cognitive restraint subscale and its adapted version for the cognitive restraint toward carbohydrates, were used as measures. Parametric tests were used for comparison between groups (Student's t test), and Pearson's correlation test to verify correlations between variables of interest. Results No differences were found between groups with and without diet concerning the level of binge eating or food craving total score. The differences found were the higher levels of cognitive restraint (p=0.01), cognitive restraint for carbohydrates (p=0.01) and subscales of 'guilt about food craving' (p=0.04) in the Low-Carb Diet Group. Conclusion Individuals with binge eating and a history of low-carb diet have greater cognitive restraint toward carbohydrates and association with altered eating attitudes (guilt about food craving).

Antibacterial Activity of Plant Lectins: a Review

Abstract Lectins are proteins that form a heterogeneous group, capable of binding specifically and reversibly to carbohydrates. They occur in various types of organisms, having different functions, in plants they are present in almost all structures, however with greater proportion in seeds roots and rhizomes. This review aims to provide a more detailed understanding of the antibacterial action of lectins and their biotechnological potential against pathogenic bacteria in the last ten years. Several mechanisms of action are described for the antibacterial activity of these proteins among which the best known occurs due to the interaction between the binding site of the lectin and the carbohydrates exposed on the bacterial cell surface. In vivo studies demonstrate that lectins act on the cascade of cytokines and influencing the level of nitric oxide as ways to decrease bacterial infection. To date, lectins have performed a wide antibacterial activity, emphasizing that each lectin acts according to its carbohydrate specificity, in this way, it is possible to have a distinct performance according to the plant species that are extracted. Thus, being an alternative to the antibacterial resistance that occurs in response to antibiotics. Furthermore, more studies with this theme are necessary for clinical application.

ABSTRACT Introduction: Children with Down syndrome (DS) may have a prevalence of neophobia and food selectivity, overweight, and obesity. A healthy and balanced diet is of utmost importance for the proper growth of these children. Objective: To evaluate the adequacy of diet components and the nutritional status of children and adolescents with Down syndrome followed up at the outpatient care of genetic pediatrics, Hospital das Clínicas de Botucatu. Method: A cross-sectional descriptive clinical study, with a collection of clinical data and nutritional assessment, using anthropometric data and dietary records to evaluate the diet. Statistical analysis of the Chi-square and Tukey tests were performed. Results: A total of 35 children and two adolescents were included. Nutritional diagnoses were 2.7% lean, 81.1% eutrophic, 8.1% obese, and 8.1% at risk or overweight. There was an excess of lipid intake in overweight and obese children, and a fiber-deficient diet was prevalent since the first year of age, as well as extra calories and adequate iron and zinc intake. Among the two adolescents, a diet with deficits in macro and micronutrients, except for vitamin C and cholesterol, stood out. Conclusions: A diet with an excess of calories, carbohydrates, and lipids, as well as a fiber-deficient diet, indicates an unbalanced diet among children and adolescents with DS, especially after one year of age, despite their adequate nutritional status.

La suplementación con ácido ascórbico atenúa el trastorno metabólico inducido por un derivado de juglona / Ascorbic supplementation attenuates juglone induced metabolic derangement

Los derivados de juglona, como 2-(4-hidroxifenil) amino-1,4-naftoquinona (Q7), son conocidos agentes antitumorales. Ellos generan especies reactivas de oxígeno (ROS), que podrían producir un desbalance de ROS y un metabolismo anormal de lípidos. El objetivo del estudio fue evaluar el efecto del ascorbato sobre el metabolismo de lípidos y carbohidratos en condición de estrés oxidativo inducido por Q7. A ratas Wistar macho, se les administró oralmente Q7 (10 mg/Kg) y/o ascorbato (500 mg/Kg) durante 20 días. Las ratas tratadas con Q7 mostraron un aumento de los triglicéridos en suero, del colesterol VLDL y de los niveles de peróxidación lipídica. Cuando el tratamiento con Q7 fue seguido de la administración de ascorbato (500 mg/Kg), observamos una disminución de los triglicéridos en suero, del colesterol VLDL y de la peroxidación lipídica. La administración oral de ascorbato redujo el aumento de lípidos inducido por Q7 y la glicemia postprandial. Esto podría estar asociado con la actividad redox del ascorbato, que reduce el estrés oxidativo inducido por Q7. Concluimos que el ascorbato modula el aumento del metabolismo de lípidos y carbohidratos inducido por Q7.

Juglone derivatives like 2-(4-hydroxyphenyl) amino-1,4-naphthoquinone (Q7) are used as antitumor agents, and act through reactive oxygen species (ROS) generation. Such may lead to abnormal lipid metabolism and ROS dysregulation. The objective of this study was to evaluate the effect of ascorbate on the metabolism of lipids and carbohydrates following Q7-induced oxidative stress. Male Wistar rats were administered Q7 (10 mg/Kg) and/or ascorbate (500 mg/Kg) orally for 20 days. Rats treated with Q7 showed an increase in serum triglycerides, VLDL cholesterol and lipid peroxidation levels. When Q7 treatment was followed up by ascorbate (500 mg/Kg) administration, we observed a reduction in serum triglycerides, VLDL cholesterol and lipid peroxidation. The oral administration of ascorbate reduced the Q7-induced increases in lipids, and postprandial glycemia. This could be associated with the redox activity of ascorbate that reduced the oxidative stress induced by Q7. We thus conclude that ascorbate modulates the Q7-induced increase of lipid and carbohydrate metabolism.
