Abstract Sesbania virgata (Cav.) Pers. seeds are protein sources with health and environmental benefits. In this research, proteins with lectin activity were identified in a protein fraction from S. virgata seeds (PFLA), as well its antioxidant and antimicrobial potentials, in addition to cytotoxic effects. To obtain PFLA, seed flour was homogenized in Glycine-NaOH (100 mM; pH 9.0; NaCl 150 mM) and precipitated in ammonium sulfate. PFLA concentrates bioactive lectins (32 HU/mL, 480 HU/gFa, 18.862 HU/mgP) and essential amino acids (13.36 g/100g protein). PFLA exerts antioxidant activity, acting as a promising metal chelating agent (~77% of activity). Analyzes of cell culture assay results suggest that antioxidant activity of PFLA may be associated with the recruitment of essential molecules to prevent the metabolic impairment of cells exposed to oxidative stress. PFLA (256 – 512 µg/mL) also exhibits antifungal activity, inhibiting the growth of Aspergillus flavus, Candida albicans, Candida tropicalis and Penicillium citrinum. Cytotoxic analysis indicates a tendency of low interference in the proliferation of 3T3 and HepG2 cells in the range of PFLA concentrations with biological activity. These findings support the notion that PFLA is a promising adjuvant to be applied in current policies on the management of metal ion chelation and fungal infections. Cav. Cav (Cav.

Abstract Introduction: Postoperative nausea and vomiting is still a common complication. Serotonin receptor antagonists are commonly used in clinical practice for antiemetic prophylaxis. Interin-dividual variations in drug response, including single nucleotide polymorphisms, are related to pharmacokinetic and pharmacodynamic changes in these drugs and may lead to a poor therapeutic response. This study aimed to evaluate the influence of CYP2D6 isoenzyme and ABCB1 gene polymorphisms on the frequency of postoperative nausea and vomiting with the use of ondansetron or palonosetron. Methods: A randomized, double-blind clinical trial including 82 women aged 60 years or over undergoing laparoscopic cholecystectomy was conducted. Patients were randomized to receive either ondansetron or palonosetron for postoperative nausea and vomiting prophylaxis. DNA was extracted from saliva. Genetic polymorphisms were analyzed by real-time polymerase chain reaction. The following polymorphisms were analyzed: rs3892097 C/T, rs1128503 A/G, rs16947A/G, rs1065852 A/G, rs1045642 A/G, rs2032582 C/A, and rs20325821 C/A. Results: Overall, vomiting, and severe nausea occurred in 22.5% and 57.5% of patients, respectively. In the palonosetron group, patients with the GG genotype (rs16947 A/G) experienced more severe nausea (p = 0.043). In the ondansetron group, patients with the M genotype (rs16947 A/G) presented mild nausea (p = 0.034), and those with the AA genotype (rs1065852 A/G) experienced more vomiting (p = 0.034). Conclusion: A low antiemetic response was observed with ondansetron in the presence of the AA genotype (rs16947 A/G) and the AA genotype (rs1065852 A/G), and a low therapeutic response was found with palonosetron in the presence of the GG genotype (rs16947 A/G) in laparoscopic cholecystectomy.

ABSTRACT Emulsifiers and exogenous lipases are feed additives used to increase lipid utilization in broiler diets. A meta-analysis was carried out to quantify the effects of the supplementation of emulsifiers and exogenous lipases on broiler weight gain (BWG, g/broiler/d) and feed conversion ratio (FCR, g/g) during the whole production cycle. Studies were obtained from the PubMed, Scielo, Science Direct, Scopus, and Web of Science databases. A total of 2669 studies were identified, 25 of which composed the database for the meta-analysis, representing data from a total of 14,643 broilers. These results demonstrate that there is evidence in the literature supporting that supplementation with emulsifiers or lipases improves broiler weight gain and feed conversion during the whole production cycle. However, the effect of the additives is influenced by bird sex, lipid source and concentration, type of additive and concentration, energy level of the feed, and bird strains. The isolated use of emulsifiers increases weight gain by 1.62g/day and reduces feed conversion by 0.04. However, there is no evidence that exogenous lipase use alone improves weight gain or feed conversion in broilers during the whole production cycle. The latter result may be due to the small number of studies with the additive in question, rather than its possible effects on weight gain and feed conversion. Therefore, further investigation should be conducted on this topic, especially studies on females fed diets supplemented with lipases. metaanalysis meta analysis BWG, BWG (BWG g/broiler/d gbroilerd g d FCR, FCR (FCR g/g gg cycle PubMed Scielo Direct Scopus databases 266 identified 2 metaanalysis, analysis, 14643 14 643 14,64 However sex concentration strains 162gday gday 1 62g day 004 0 04 0.04 question Therefore topic 26 1464 64 14,6 00 0.0 146 6 14, 0.

Abstract The purpose of this paper was to avaliate of the concentration of hydrocolloids (low methoxyl pectin [LMP], guar gum [GG], and carrageenan gum [CG]) in low-calorie orange jellies in order to maximize the amount of bioactive compounds and antioxidant capacity, and to study the influence on degradation these compounds. A mixture design with seven tests was used to analyze the total phenolic compounds, ascorbic acid (vitamin C) and antioxidant capacity (ABTS, DPPH and β-carotene/linoleic acid methods). The results were analyzed by response surface methodology and the Scott-Knott mean test at a significance level of 5% (p ≤ 0.05). In general, the regions containing 0.5% GG and 0.5% GC had higher levels of the variables under study, and this combination preserved the bioactive compounds and antioxidant activity of jellies in relation to that of orange juice. low LMP, LMP , [LMP] GG, [GG] CG [CG] lowcalorie calorie vitamin C ABTS, ABTS (ABTS βcarotene/linoleic βcarotenelinoleic β carotene/linoleic carotene linoleic methods. methods . methods) ScottKnott Scott Knott 5 p 0.05. 005 0.05 0 05 0.05) general 0.5 juice [LMP [GG [CG βcarotene carotenelinoleic 00 0.0 0.

Abstract This study characterized the beverage of passion fruit and whey protein added with Lacticaseibacillus rhamnosus GG (LGG). The acidity, pH, soluble solids, protein, phenolic compounds, and color of the sample did not differ during the 28 days at 5°C. The LGG counts in the beverage remained >7.70 log CFU/mL during the evaluation period. However, the LGG count was significantly reduced after the in vitro simulated gastrointestinal tract (GIT) evaluation (reduction of 5 logarithmic cycles after processing). On the other hand, the LGG resistance to GIT increased during the shelf-life of the beverage (LGG count of ~ 4.0 log CFU/mL after 28 days). In addition, the LGG count after GIT increased by approximately 2.0 logarithmic cycles when microencapsulation and fermentation technologies were used in beverage processing. Thus, the product has the potential to be commercialized, due to high viability of LGG use to increase the resistance of LGG to GIT. LGG. .

Abstract This study aimed to develop an acerola smoothie using gellan gum (GG) as a texture modifier. Samples were developed with three concentrations of GG (0.1%, 0.2%, 0.3% w/v) and a control sample (without GG). Physicochemical, rheological, and sensory properties were evaluated. The smoothie samples showed increased color intensity than the control, with a tendency to yellow and red colors. However, the hydrocolloid concentration did not affect the samples' pH values (4.13 to 4.17). GG presence favored an increase in the samples' viscosity, classified as pseudoplastic fluid. There was a reduction in vitamin C in samples with GG (422.18 to 430.49 mg/100 g), however, the values remained close to the control (448.89 mg/100 g). There was greater sensory acceptance by the sample with intermediate texture (0.2% GG), which obtained a higher frequency for the attributes "homogeneous" and "acerola flavor".

Vocal fold leukoplakia (VFL) has a risk of malignant transformation. Therefore, patients can have symptoms such as dysphonia, vocal strain, difficulty breathing, and dysphagia. Additionally, there is a genetic predisposition that can be associated with genetic polymorphisms. We aimed to evaluate the influence of genetic polymorphisms and protein levels in the etiology of VFL. Our study followed the PRISMA checklist and was registered on PROSPERO database. The questions were: “Are genetic polymorphisms involved in the etiology of VFL? Are protein levels altered in patients with VFL?”. Eligibility criteria were case control studies that compared the presence of polymorphisms or/and protein levels of subjects diagnosed with VFL and healthy controls. Of the 905 articles retrieved, five articles with a total of 1038 participants were included in this study. The C allele of the single nucleotide polymorphisms (SNP)-819 T/C IL-10, A allele of the SNP -592 A/C IL-10, CT genotype of the SNP rs11886868 C/T BCL11A, GG genotype of the SNP rs4671393 A/G BCL11A, LL genotype, and L allele of (GT)n repeat polymorphisms of the HO-1 were risk factors for VFL development. Nevertheless, there was a lack of association between VFL and the -1082 A/G IL-10, rs14024 CK-1, and -309 T/G Mdm2 SNPs. The concentrations of the MDM2, BCL11A, and HO-1 proteins were modified, while IL-10 levels were normally expressed in these subjects. In conclusion, most markers evaluated in this review could be potential indicators to develop effective therapies, avoiding a malignant transformation of the lesion.

OBJECTIVES: In the Human Epidermal Growth Factor Receptor-2 (HER2) rs1136201 variant, the presence of the G allele may promote cellular alterations and increase breast cancer risk, in addition to enhanced cellular proliferation, tumor aggressiveness, and metastases. The aim of this study was to investigate the presence of the single-nucleotide polymorphism (SNP) variant, rs1136201, within the HER2 gene in women from the Northeastern region of Brazil and breast cancer risk. METHODS: The study included 140 women who were divided into two groups, case (breast cancer) and control (without breast cancer), with 70 women in each group. Peripheral blood of each woman was drawn for the study of genomic Deoxyribonucleic acid (DNA) extracted from leukocytes using the genotyping technique by real-time polymerase chain reaction. RESULTS: The GG genotype occurred in 1 woman in both groups (1.4%) (p=0.32), while the AG genotype occurred in 19 (27.2%) and 13 (18.6%) women in the case and control (p=1.00) groups, respectively. No statistically significant difference in GG and AG genotypes was observed between the case and control groups in premenopausal women (p=1.00). Furthermore, no significant difference in genotypes was observed between the groups, among postmenopausal women (p=0.14). CONCLUSION: In this study, the HER2 rs1136201 polymorphism did not show any statistically significant association with breast cancer, both in premenopausal and postmenopausal women. Nevertheless, further studies with a larger sample size should be performed to assess the association of HER2 polymorphism with breast cancer risk in women from the Northeastern region of Brazil.

RESUMO No presente estudo, foram avaliados parâmetros oftalmológicos de 38 bovinos das raças Nelore (n= 19; grupo GN) e Gir (n= 19; grupo GG), machos, com idade média de 15 meses. Os exames oftalmológicos realizados foram teste lacrimal de Schirmer 1 (TLS-1), tonometria de aplanação, retinografia e biometria por ultrassonografia em modo B. Os resultados do TLS-1, tonometria de aplanação e biometria ocular foram avaliados por meio da análise de variância (ANOVA), e as médias comparadas pelo teste de Tukey. Para o exame de retinografia, foi realizada a análise descritiva das estruturas anatômicas. O TLS-1 e a tonometria não diferiram (P≥0,05) nas comparações entre os olhos e entre os grupos raciais. A retinografia permitiu a visualização do disco óptico, dos vasos retinianos, do fundo tapetal e não tapetal, sem constatação de diferenças anatômicas entre as raças. Por meio da biometria ocular, foram observados valores maiores nos animais da raça Gir para as medidas do comprimento axial (CAx), da espessura da lente (EL) e da profundidade da câmara vítrea (CV), em ambos os eixos, horizontal (CAH) e vertical (CAV). Os exames oftalmológicos realizados podem ser executados a campo sem comprometer o bem-estar dos animais. Somente na ultrassonografia em modo B foram identificadas diferenças entre os bovinos das raças Nelore e Gir.

ABSTRACT The ophthalmological parameters were evaluated of 38 male Nelore bovine (n= 19, GN group) and Gir (n= 19, GG group), with 15 months age. The ophthalmological examinations by Schirmer 1 (TLS-1), aplanation tonometry, retinography and B-mode ultrasonography were done. The results of the TLS-1, aplanation tonometry and ocular biometry were evaluated by analysis of variance and means compared by the Tukey test. A descriptive analysis of the anatomical structures was performed for the retinography examination. TLS-1 and tonometry did not differ (P≥ 0.05) in the comparisons between the eyes and between the groups. Retinography allowed the visualization of the optic disc, retinal vessels, tapetal and non-tapetal fundus, without any anatomical differences between the breed. In the ocular biometry, higher values were observed in Gir animals for measurements of axial length (CAx), lens thickness (EL) and depth of the vitreous chamber (CV), both horizontal (CAH) and vertical (CAV) imaging planes. Ophthalmologic examinations can be performed on the field without compromising animal welfare. Differences between Nelore and Gir bovines were identified only by B-mode ultrasonography.

Resumo O perfil metabólico é uma importante ferramenta no diagnóstico de doenças metabólicas e monitoramento nutricional de animais de produção. Este trabalho teve por objetivo avaliar o escore corporal e perfil metabólico de ovelhas da raça Santa Inês criadas em sistema de semiconfinamento, ao longo do periparto, comparando esses parâmetros entre animais com gestação simples e gestação múltipla. Cinquenta e cinco ovelhas (55), sendo 43 com gestação simples e 12 com gestação gemelar, foram submetidas a coletas de sangue e avaliação do escore corporal semanalmente, entre o fim do terceiro mês de gestação e um mês pós-parto, totalizando 10 avaliações. Observaram-se diferenças na comparação entre semanas para as variáveis: Glicose, BHB, NEFA, Triglicerídeos, Cálcio, Fósforo, Uréia e Creatinina para os grupos Gestação Simples (GS) e Gestação Gemelar (GG), além de Magnésio para o primeiro grupo (p<0,005). A semana do parto e as semanas subsequentes apresentaram valores estatisticamente diferentes das semanas que precederam o parto na maioria das variáveis estudadas. Não houve diferença significativa na comparação entre os grupos GS e GG para os parâmetros avaliados. Em ambos os grupos houve redução no escore corporal das fêmeas acompanhadas, com uma queda na proporção de animais com EC3 e 4 e concomitante crescimento de EC2.

Abstract The metabolic profile represents an important tool in the diagnostic of metabolic diseases and in the nutritional monitoring of production animals. The main aim of this study was to evaluate the body scores and metabolic profile of sheep of the Santa Inês breed in a system of semi- confinement, during the peri-parturient. The body scores and metabolic profile were analysed between animals with single and multiple pregnancies. Fifty-five sheep were recruited for this study, of those, 43 with single pregnancy and 12 with twin pregnancies. The animals were submitted to blood collection and analyses of body score (BS) weekly, from the end of third month of pregnancy until one month postpartum, and those were analysed 10 times during this research. About the analyses throughout weeks, the study found different values to the variables Glucoses, BHB, NEFA, Triglycerides, Calcium, Phosphorus, Urea, and Creatinine for the Single Pregnancy (SP) and Twin Pregnancies (TP) groups (p<0,005). Moreover, distinct rates of Magnesium was noticed in the Single Pregnancy group (p<0,005). The week of birth and subsequent weeks, showed statistically different values of those from the weeks leading up to the birth in most of the variables studied. There was no significant difference in the comparison between the SP and TP groups for the parameters evaluated. In both groups, there were a decrease in the female body score, with a reduction in the proportion of animal with BS3 and 4 associated, and concomitant increase of animals with BS2 proportion.

Abstract Background: Fibromyalgia (FM) is a chronic pain syndrome characterized by generalized skeletal muscle chronic pain. Its etiology is not well defined, because there are several factors that may trigger it such as physical and/or emotional stresses, or a genetic susceptibility, involving serotonergic, dopaminergic and catecholaminergic paths. The objective of this study was to investigate the association between the strength of the lower limb, genetic polymorphism of the serotonin receptor gene HTR2a in women with fibromyalgia. Methods: In this observational study of case-control type 48 women were evaluated who belonged to the group with FM (52 ± 12 years) and 100 women in the control group (58±11 years). Socio demographic and anthropometric data were collected and peripheral blood samples for DNA extraction; genotypic analyzes were performed by means of PCR in real time by TaqMan® system. The lower limb muscle strength was assessed through the test of sitting down and standing up for 30 s. The chi-square test or Fischer Exact was used for possible associations among the variables; the t-test for independent samples was used to compare the averages among the groups; the value of significance adopted was 5%. Results: There was an association between the polymorphism of the HTR2A gene with FM, demonstrating that carriers of the genotype GG have 24.39 times more likely to develop the syndrome (IC95% 5.15-115.47; p = 0.01). It was observed an association between FM and the test to sit and stand up demonstrating that women with fibromyalgia have lower limb muscle strength ( p = 0.01). The study showed that the white race has 3.84 times more likely to develop FM (p = 0.01). Conclusion: The results of this study suggest that women of Caucasian ethnicity with GG genotype or G allele presented greater risk of developing fibromyalgia and that these patients have lower limb muscle strength compared to the control group.

RESUMO Objetivo Investigar a acurácia das medidas acústicas, isoladas e combinadas, na discriminação da intensidade do desvio vocal (GG) e da qualidade vocal predominante (QVP) em pacientes disfônicos. Método Participaram 302 pacientes do gênero feminino, com queixa vocal. A partir da vogal /ɛ/ sustentada, foram extraídas as medidas acústicas de média e desvio padrão (DP) da frequência fundamental (F0), o jitter, o shimmer e o Glottal to noise excitation (GNE) e a média dos três primeiros formantes (F1, F2, F3). A avaliação perceptivo-auditiva do GG e QVP foi realizada por três fonoaudiólogos especialistas em voz. Resultados Isoladamente, apenas o GNE obteve desempenho satisfatório na discriminação do GG e da QVP. Houve uma melhora na classificação do GG e QVP com a combinação das medidas acústicas. A média de F0, F2 e GNE (saudável × desvio leve a moderado), DP de F0, F1 e F3 (leve a moderado × desvio moderado), Jitter e GNE (moderado × desvio intenso) foram as melhores combinações para discriminar o GG. As melhores combinações para discriminação da QVP foram média de F0, Shimmer e GNE (saudável × rugosa), F3 e GNE (saudável × soprosa), média de F0, F3 e GNE (rugosa × tensa), média de F0, F1 e GNE (soprosa × tensa). Conclusão De forma isolada, o GNE mostrou-se o único parâmetro acústico capaz de discriminar o GG e a QVP. Houve um ganho no desempenho da classificação com a combinação das medidas acústicas tradicionais e formânticas, tanto para a discriminação do GG como da QVP.

ABSTRACT Purpose Investigate the accuracy of isolated and combined acoustic measurements in the discrimination of voice deviation intensity (GD) and predominant voice quality (PVQ) in patients with dysphonia. Methods A total of 302 female patients with voice complaints participated in the study. The sustained /ɛ/ vowel was used to extract the following acoustic measures: mean and standard deviation (SD) of fundamental frequency (F0), jitter, shimmer, glottal to noise excitation (GNE) ratio and the mean of the first three formants (F1, F2, and F3). Auditory-perceptual evaluation of GD and PVQ was conducted by three speech-language pathologists who were voice specialists. Results In isolation, only GNE provided satisfactory performance when discriminating between GD and PVQ. Improvement in the classification of GD and PVQ was observed when the acoustic measures were combined. Mean F0, F2, and GNE (healthy × mild-to-moderate deviation), the SDs of F0, F1, and F3 (mild-to-moderate × moderate deviation), and mean jitter and GNE (moderate × intense deviation) were the best combinations for discriminating GD. The best combinations for discriminating PVQ were mean F0, shimmer, and GNE (healthy × rough), F3 and GNE (healthy × breathy), mean F 0, F3, and GNE (rough × tense), and mean F0 , F1, and GNE (breathy × tense). Conclusion In isolation, GNE proved to be the only acoustic parameter capable of discriminating between GG and PVQ. There was a gain in classification performance for discrimination of both GD and PVQ when traditional and formant acoustic measurements were combined.

ABSTRACT The objective of this study was to evaluate the effect of the dietary addition of different levels of glycerin on the performance, litter moisture, pododermatitis incidence, and carcass and parts yield of broilers. In total, 1,610 broilers were reared in 35 pens with 46 birds each. A completely randomized experimental design, with five treatments with seven replicates was applied. The experimental treatments were: T1: control diet; T2: dietary inclusion of 5% glycerin from 1-42 days of age; T3: dietary inclusion of 10% glycerin from 1-42 days of age; T4: dietary inclusion of 5% glycerin from 7-42 days of age; T5: dietary inclusion of 10% glycerin from 7-42 days of age. The diets containing glycerin fed since the pre-starter period improved broiler weight gain and feed conversion ratio, but did not influence feed intake or livability. At the end of the experiment, the production efficiency index of the broilers fed 10% glycerin during the entire rearing period was significantly reduced compared with the other treatments. Litter moisture in the pens of broilers fed 10% glycerin during the entire rearing period was higher compared to the other treatments since day 21.Diets containing 10% glycerin, both for the entire rearing period (1-42 days) or only after the pre-starter phase (7-42 days), influenced broiler performance and incidence of severe pododermatitis, reducing the production efficiency indexes at 42 days. Glycerin may be added up to 5% in broiler´s diets with no effect on performance, litter moisture and carcass yield, indicating that this co-product of the biodiesel industry can be used as an alternative feedstuff for broilers.

Human papillomavirus (HPV) infections are strongly associated with the development of cervical intraepithelial neoplasias and invasive cervical cancer. Polymorphisms in cytokine-encoding genes and behavioural cofactors could play an important role in protecting an individual against viral infections and cancer. Here, we investigated whether IL-6 -174 G>C, IL-8 +396 G>T, and TGF-β1 +869 G>C and +915 G>C polymorphisms were associated with susceptibility to HPV infection in women from north-east (Pernambuco) Brazil. We analysed 108 healthy uninfected women (HC) and 108 HPV-positive women with cervical lesions. Genetic polymorphisms were assessed using Sanger sequencing and polymerase chain reaction-restriction fragment length polymorphism. Comparison of the distribution of the genotypic and allelic frequencies of the IL-18 +396 T>G polymorphism between HPV infected woman an uninfected controls showed that the GG genotype and G allele were both more frequent in the HC group, and were associated with protection from HPV infection (p = 0.0015; OR = 0.29 CI95% = 0.13-0.61; p = 0.0005; OR = 0.45 CI95% 0.29-0.7, respectively). Individuals from the control group could have previously had HPV infection that was spontaneously eliminated; however, it was undetectable at the time of sample collection. Based on our findings, we hypothesize that the IL-8 +396 G>T polymorphism could interfere with susceptibility to HPV infection, by modulating the ability of immune system to fight the virus.
