RESUMEN

Preeclampsia (PE) is a hypertensive pregnancy syndrome associated with target organ damage and increased cardiovascular risks, necessitating antihypertensive therapy. However, approximately 40% of patients are nonresponsive to treatment, which results in worse clinical outcomes. This study aimed to compare circulating proteomic profiles and identify differentially expressed proteins among 10 responsive (R-PE), 10 nonresponsive (NR-PE) patients, and 10 healthy pregnant controls (HP). We also explored correlations between these proteins and clinical data. Plasma protein relative quantification was performed using mass spectrometry, followed by bioinformatics analyses with the UniProt database, PatternLab for Proteomics 4.0, and MetaboAnalyst software (version 6.0). Considering a fold change of 1.5, four proteins were differentially expressed between NR-PE and R-PE: one upregulated (fibronectin) and three downregulated (pregnancy-specific beta-1-glycoprotein 1, complement C4B, and complement C4A). Between NR-PE and HP, six proteins were differentially expressed: two upregulated (clusterin and plasmin heavy chain A) and four downregulated (apolipoprotein L1, heparin cofactor II, complement C4B, and haptoglobin-related protein). Three proteins were differentially expressed between R-PE and HP: one downregulated (transthyretin) and two upregulated (apolipoprotein C1 and hemoglobin subunit beta). These findings suggest a complex interplay of these proteins involved in inflammatory, immune, and metabolic processes with antihypertensive therapy responsiveness and PE pathophysiology.

RESUMEN

PREMISE: Legumes establish mutualistic interactions with pollinators and nitrogen (N)-fixing bacteria that are critical for plant reproduction and ecosystem functioning. However, we know little about how N-fixing bacteria and soil nutrient availability affect plant attractiveness to pollinators. METHODS: In a two-factorial greenhouse experiment to assess the impact of N-fixing bacteria and soil types on floral traits and attractiveness to pollinators in Chamaecrista latistipula (Fabaceae), plants were inoculated with N-fixing bacteria (NF+) or not (NF-) and grown in N-rich organic soil (+N organic soil) or N-poor sand soil (-N sand soil). We counted buds and flowers and measured plant size during the experiment. We also measured leaf, petal, and anther reflectance with a spectrophotometer and analyzed reflectance curves. Using the bee hexagon model, we estimated chromatic contrasts, a crucial visual cues for attracting bees that are nearby and more distant. RESULTS: NF+ plants in -N sand soil had a high floral display and color contrasts. On the other hand, NF- plants and/or plants in +N organic soil had severely reduced floral display and color contrasts, decreasing floral attractiveness to bee pollinators. CONCLUSIONS: Our findings indicate that the N-fixing bacteria positively impact pollination, particularly when nutrients are limited. This study provides insights into the dynamics of plant-pollinator interactions and underscores the significant influence of root symbionts on key floral traits within tropical ecosystems. These results contribute to understanding the mechanisms governing mutualisms and their consequences for plant fitness and ecological dynamics.

RESUMEN

Color is a crucial sensory attribute that guides consumer expectations. A high-performance pequi carotenoid extraction process was developed using ionic liquid-based ethanolic solutions and a factorial design strategy to search for a potential substitute for the artificial azo dye yellow tartrazine. All-trans-antheraxanthin was identified with HPLC-PAD-MSn for the first time in pequi samples. [BMIM][BF4] was the most efficient ionic liquid, and the maximization process condition was the solid-liquid ratio R(S/L) of 1:3, the co-solvent ratio R(IL/E) of 1:1 ([BMIM][BF4]: ethanol), and three cycles of extraction with 300 s each and yielded 107.90 µg carotenoids/g of dry matter. The ionic liquid-ethanolic solution recyclability was accomplished by freezing and precipitating with an average recovery of 79 %. In CIELAB parameters, pequi carotenoid extracted with [BMIM][BF4] was brighter and yellower than the artificial azo dye yellow tartrazine. A color change of 11.08 and a hue* difference of 1.26° were obtained. Furthermore, carotenoids extracted with [BMIM][BF4] showed antioxidant activity of 35.84 µmol of α-tocopherol. These findings suggest the potential of employing the pequi carotenoids to replace the artificial azo dye yellow tartrazine in foods for improved functional properties.

RESUMEN

The role of periodontal pathogens in the initiation and progression of atherosclerosis has been extensively researched, yet a precise causal mechanism has not been established. The subgingival microbiota may be a source of dissemination and may contribute to the development of atherosclerosis; hence this study attempted to characterize and compare the subgingival and atherosclerotic plaques. Plaque samples were subjected to 16S rRNA-based metagenomics to study microbiota associated with subgingival and atherosclerotic plaques collected from patients with coronary artery disease. The PCoA analysis showed that the microbiomes of subgingival plaques were highly scattered and showed a diverse microbial composition, unlike the atherosclerotic plaques that did not show evident variability in the microbial composition and formed a close distinct group. The abundance of various genera in the subgingival plaques revealed Fusobacterium (11%), Acinetobacter (13%), Veillonella (9%), and Prevotella (11%) among the top ten genera. The atherosclerotic plaques contained Acinetobacter (39%), Chryseobacterium (9%), Rhizobium (5%), and Staphylococcus (4%). All the patients examined in this study had either generalized or localized periodontitis with varying degrees of severity. The community microbiota analysis revealed that 22 bacterial genera were shared between two different plaques, with Acinetobacter being dominant. Based on the Human Oral Microbiome Database, 55% of the shared microbiota in this study have been listed as periodontal microbiota, with some of them found in increased proportions in patients with periodontitis suggesting the translocation of bacteria from the periodontal pockets into the circulation. This study provides valuable insights into the possible relationship between periodontal pathogens and atherosclerotic cardiovascular disease.

RESUMEN

The addition of corn distillers dried grains (corn-DDG) to pig diets has been limited due to concerns about fiber content. The aim of the present study was to determine the metabolizable energy of corn-DDG (Exp. I) and the dose-response effects of dietary xylanase plus ß-glucanase on the nutrient and energy digestibility of growing pigs fed diets containing 25% corn-DDG (Exp. II). Pigs in individual cages were subjected to feeding periods of 5 days for voluntary feed intake quantification followed by 5 days for collection of feces and urine. In Exp. I, 10 castrated male pigs with 61.10 ± 3.25 kg BW distributed in a randomized complete block design experiment with five replications were fed a reference diet or a test diet (75% reference diet plus 25% corn-DDG). In Exp. II, 10 castrated male pigs with 29.69 ± 3.57 kg BW distributed in a Latin square design (two squares with four replicates in time) experiment were fed with 5 dietary xylanase plus ß-glucanase levels (0, 50, 100, 200, or 400 mg/kg) added to diets formulated with 25% corn-DDG. The corn-DDG had 26.5% crude protein, 5.94% ether extract, 55.5% neutral detergent fiber (NDF), and 4.248 kcal/kg gross energy. The metabolizable energy of corn-DDG was 3.657 ± 189 kcal/kg. Increasing dietary xylanase plus ß-glucanase quadratically influenced (P < 0.05) the NDF digestibility and digestible energy in growing pigs fed diets containing 25% corn-DDGS. Compared to the control, dietary xylanase plus ß-glucanase addition increased digestibility and reduced metabolizability of crude protein. The addition of dietary xylanase plus ß-glucanase to growing pig diets containing corn-DDG increased NDF digestibility, allowing for additional dietary energy and protein availability.

RESUMEN

Currently, obesity is considered a global public health problem. It is the main risk factor for noncommunicable diseases and reproductive complications, such as recurrent miscarriage (RM). RM affects approximately 1% of couples of reproductive age, and recent studies suggest that its prevalence is increasing. Immunological abnormalities may be responsible for a significant number of cases of unexplained RM. Obesity is recognized as a chronic low-grade inflammatory condition. The accumulation of fat in obese adipose tissue promotes changes in the local and systemic immune response. Adipokines, exosomes, micro-RNAs, lipids, and other factors released or secreted by adipose tissue are responsible for the interconnection between obesity and the immune system. Obesity-induced dysregulation of the innate and acquired immune response is also involved in the immunopathology of pregnancy loss in patients with unexplained RM. Therefore, understanding the communication pathways between maternal adipose tissue and the immune response in women living with obesity and RM is an important objective. Thus, diagnostic tools and new immunomodulatory therapies may be proposed for the management of patients with concurrent obesity and RM.

RESUMEN

Vibrio vulnificus an opportunistic human pathogen native to marine/estuarine environment, is one of the leading causes of death due to seafood consumption and exposure of wounds to seawater worldwide. The present study involves the whole genome sequence analysis of an environmental strain of V. vulnificus (clinical genotype) isolated from seafood along the Mangaluru coast of India. The sequenced genome data was subjected to in-silico analysis of phylogeny, virulence genes, antimicrobial resistance determinants, and secretary proteins using suitable bioinformatics tools. The sequenced isolate had an overall genome length of 4.8 Mb and GC content of 46% with 4400 coding DNA sequences. The sequenced strain belongs to a new sequence type (Multilocus sequence typing) and was also found to branch with a phylogenetic lineage that groups the most infectious strains of V. vulnificus. The seafood isolate had complete genes involved in conferring serum resistance yet showed limited serum resistance. The study identified several genes against the antibiotics that are commonly used in their treatment, highlighting the need for alternative treatments. Also, the secretory protein analysis revealed genes associated with major pathways like ABC transporters, two-component systems, quorum sensing, biofilm formation, cationic antimicrobial peptide (CAMP) resistance, and others that play a critical role in the pathogenesis of the V. vulnificus. To the best of our knowledge, this is the first report of a detailed analysis of the genomic information of a V. vulnificus isolated from the Indian subcontinent and provides evidence that raises public health concerns about the safety of seafood.

RESUMEN

Perturbation-based balance training (PBT) exposes individuals to a series of sudden upright balance perturbations to improve their reactive postural responses. In this study, we aimed to evaluate the effect of a short PBT program on body balance recovery following a perturbation in individuals with freezing of gait due to Parkinson's disease. Volunteers (mean age = 64 years, SD = 10.6) were pseudorandomly assigned either to a PBT (n = 9) or to a resistance training (RT, n = 10) group. PBT was implemented through balance perturbations varying in the kind, direction, side and magnitude of support base displacements. Both groups exercised with progressive difficulty/load activities twice a week for 4 weeks. Specific gains and generalization to dual-tasking and faster-than-trained support base displacements were evaluated 24 h after the end of the training, and retention was evaluated after 30 days of no training. Results showed that, compared with RT, PBT led to more stable postural responses in the 30-day retention evaluation, as indicated by decreased CoP displacement, velocity and time to direction reversal and reduced numbers of near-falls. We found no transfer either to a dual task or to a higher perturbation velocity. In conclusion, a training program based on diverse unpredictable balance perturbations improved the stability of reactive postural responses to those perturbations suffered during the training, without generalization to more challenging tasks.

RESUMEN

INTRODUCTION: Cognition and emotional state are domains that highly interfere with postural control in individuals with Parkinson's disease (PD). This study aims to find associations between executive function, anxiety, depression, and reactive and anticipatory postural control domains in individuals with moderate-to-severe Parkinson's disease. METHODS: In this study, 34 individuals with PD while on medication were thoroughly assessed for postural control in perturbed, quiet standing and stepping. We performed multiple linear stepwise regressions using postural variables as dependent and cognitive/emotional as independent variables. RESULTS: The results showed that cognitive flexibility explained 23 % of anticipatory postural adjustments (APA) duration, inhibitory control explained 42 % of instability on a malleable surface, anxiety explained 21 % of APA amplitude, and 38 % of reactive postural response amplitude. CONCLUSION: Our results highlight the impact of emotional and cognitive states on particular domains of postural control in individuals with PD while on medication. These results may have significant implications for future treatments, mainly considering the predictors for postural control domains, which were consistent with the assumption that impairments in affective and executive domains underlie posture. As we have shown that cognitive and emotional states influence postural control domains in individuals with PD, this should be taken into account in rehabilitation protocols.

RESUMEN

BACKGROUND: The Pierre Robin Sequence presents heterogeneous symptoms, and each newborn can manifest from mild breathing and feeding difficulties to severe complications, as well as a predisposition to present changes in growth and neuropsychomotor development in the first years of life. OBJECTIVE: The aims were to evaluate and associate the neuropsychomotor development of zero- to 12-month-old children with Pierre Robin sequence (PRS) in the personal-social, fine motor-adaptive, language, and gross motor aspects. METHODS: The subjects of the study were 17 infants of both sexes with PRS admitted to the special care unit (SCU) of a reference hospital in the interior of the state of São Paulo, Brazil, in the age range of 20 days to 263 days. Developmental assessments were performed using the Denver Development Screening Test II. The evaluations were carried out in the SCU, with duration of 30 minutes each. Statistical analysis was descriptive using the Mann-Whitney test, two-proportion equality test, and Spearman correlation. The level of significance was set at 0.05. RESULTS: According to Denver Development Screening Test II, median 78.5 of the babies were at risk for developmental delay identified by the Denver II Test (n = 14, 82.4%). For the developmental areas analyzed by the test there was statistically significant difference in language area. CONCLUSION: The babies aged up to 12 months with PRS in this study presented risks for delay in neuropsychomotor development in language, gross motor, fine motor-adaptive, and personal-social aspects, and this finding should be considered to set goals in family orientation and intervention.

RESUMEN

The food industry uses dyes mainly to overcome color loss during the processing and storage of products, with the azo dyes currently being the most employed. Studies on the safety of using these dyes in foods started in the 1950s and have indicated the potential for concern. This review discusses the risk assessment of food intake containing artificial azo dyes. There are case reports and, subsequently, double-blind placebo-controlled trials in some individuals who may experience adverse effects from the intake of azo dyes, but it is unclear whether these adverse effects are restricted to specific populations or more generalized. In view of this, different toxicological endpoints are evaluated to verify toxic effects in in vitro and in vivo models and to establish the no observed adverse effect level. Exposure estimation studies have shown that human exposure to azo dyes via oral intake is mainly below the acceptable daily intake established by advisory bodies. However, most countries do not have studies that estimate the oral intake of azo dyes. In this case, local food diversity and racial-ethnic specificities are not considered when stating the exposure estimate is below the acceptable daily intake for the human population and thus may not represent actual intake. Concerning the scenario established above, this review discusses the most critical gaps to be overcome to contribute to the direction of future studies and the development of more effective public policies concerning the safety of the intake of artificial azo dyes.

RESUMEN

The Amazonian region is composed by many kinds of environments, including the Amazonian savannas, which comprise about 5% of the Amazon biome in Brazil. The biota of Amazonian savannas is poorly known, especially for insects. In this study, we performed a faunistic inventory of flesh flies (Diptera: Sarcophagidae) of four Brazilian Amazon savannas, where we recorded two subfamilies, 16 genera, and 40 species, two of which are described as new to science: Lepidodexia (Notochaeta) helenae sp. nov. and Lipoptilocnema augustoi sp. nov. Oxysarcodexia graminifoliaSouza, Pape & Thyssen, 2020 is recorded for the first time for Brazil. Dexosarcophaga paulistanaLopes (1982), Helicobia biplagiataDodge, 1966, Helicobia cearensisTibana, 1976, Oxysarcodexia simplicoides (Lopes, 1933), and Oxyvinia excisa (Lopes, 1950) are newly recorded for the Brazilian Amazon. Oxysarcodexia nitidaSoares & Mello-Patiu, 2010 is a new record for the state of Pará. The species D. paulistana is redescribed, and photographs and detailed illustrations of male terminalia are provided.

RESUMEN

Aim: This work examined whether ARG1 (rs2781659, rs2781667, rs2246012 and rs17599586) and ARG2 (rs3742879 and rs10483801) single-nucleotide polymorphisms (SNPs) are associated with antihypertensive therapy responsiveness in preeclampsia (PE) and their effects on arginase isoforms and nitrite concentrations in responsive and nonresponsive patients. Methods: SNP genotypes were determined by TaqMan assays. Plasma arginase levels were measured by ELISA and nitrite concentrations were measured using an ozone-based chemiluminescence assay. Results: The G allele for ARG2 rs3742879 (A>G) was less frequent in nonresponsive compared with responsive patients (15.5% vs 24.7%, respectively) and the G carriers of the nonresponsive subgroup had lower arginase 2 (9.2 ± 7.5 ng/ml vs 19.1 ± 17.3 ng/ml) and higher nitrite concentrations (110.2 ± 52.8 nM vs 78.5 ± 37.9 nM) than carriers of the AA genotype (all p < 0.05). Conclusion: ARG2 SNP rs3742879 is associated with diminished arginase 2 levels and increased nitric oxide formation in nonresponsive PE patients.

RESUMEN

A new species of Sarcophagidae (Diptera) in the genus Helicobia Coquillett, Helicobia neuzalmeidae sp. nov., is described based on two male specimens obtained from pig carcasses in savanna-like vegetation in northeastern Brazil (state of Maranhão) during a forensic study. The holotype was obtained from a larva that abandoned the pig carcass to pupate, whereas the paratype was collected with a trap placed above the cage containing the carcass. This is the first record of a Helicobia species reared from a vertebrate carcass.

RESUMEN

BACKGROUND: People with Parkinson's disease (PwPD) showed impairments of balance control which can be aggravated by the presence of higher interlateral postural asymmetry caused by a distinct dopaminergic loss in the substantia nigra between cerebral hemispheres. RESEARCH QUESTION: We evaluate asymmetries between the more and the less affected leg in PwPD in responses to unanticipated stance perturbations. METHODS: Sixteen 16 PwPD participated in the experiment that consisted of recovering a stable upright stance, keeping the feet in place, in response to a perturbation caused by a sudden release of a load equivalent to 7 % of the participant's body mass. Anterior displacement and velocity of the center of pressure (CoP), the latency of gastrocnemius medialis muscle (GM) activation onset, rate of GM activation, and normalized magnitude of muscular activation were analyzed. RESULTS: Analysis revealed significantly rate (p = 0.04) and magnitude (p = 0.02) higher activation of GM in the less affected limb. No significant effects of the leg were found for GM activation latency or CoP-related variables. SIGNIFICANCE: There is a higher contribution of the less affected leg in automatic postural responses in PwPD.

RESUMEN

No Sistema Único de Saúde (SUS) os Agentes Comunitários de Saúde (ACS) estão em constante contato com o território em que atuam, pela sua função e papel de morador, resultando em consequências ambíguas no estabelecimento de suas ações. Assim, o presente estudo busca compreender o papel dos Agentes Comunitários de Saúde, sua relação com o território, unidade e profissionais, e os processos de saúde e adoecimento no desempenho da função. Trata-se de um estudo qualitativo no formato de pesquisa participante, por meio de entrevista semiestruturada com 6 ACS, que também foram acompanhados em suas atividades diárias. A análise de conteúdo dos dados obtidos por diário de campo e entrevista possibilitou a identificação de 3 categorias: Papel dos ACS; Relação com a Equipe, e Saúde e Sofrimento dos ACS. O sofrimento dos ACS decorre da vigilância sobre seu trabalho, dificuldades no relacionamento interpessoal com a equipe, adversidades no território e sobrecarga de trabalho. Identifica-se que são profissionais muitas vezes subestimados e incompreendidos


In the Unified Health System, Community Health Agents (CHA) are in constant contact with the territory in which they operate, due to their role and role as residents, resulting in ambiguous consequences in the establishment of their actions. Thus, the present study seeks to understand the role of Community Health Agents, their relationship with the territory, unit and professionals, and the processes of health and illness in the performance of the function. This is a qualitative study in the form of participatory research, through a semi-structured interview with 6 CHA, who were also monitored in their daily activities. The content analysis of the data obtained by field diary and interview enabled the identification of 3 categories: Role of the CHA; Relationship with the Team, and Health and Suffering from the CHA. The CHA's suffering stems from surveillance over their work, difficulties in interpersonal relationships with the team, adversities in the territory and work overload. It is identified that they are professionals often underestimated and misunderstood.

RESUMEN

We evaluated the environmental quality in mangrove areas of the Western Atlantic with different levels and history of contamination, considering biomarkers for the crab Ucides cordatus. For this purpose, specimens were collected in two climatic seasons (rainy and dry seasons) and assays of genotoxicity (MN, micronucleus), cytotoxicity (NRRT, neutral red retention time) and biochemical (MT, metallothionein; and LPO, lipoperoxidation) were conducted. In the most impacted mangroves, there was an increase in the mean of micronucleus (frequency of MN/1000), which was associated with a shorter retention time (minutes of NRRT). In contrast, the most pristine areas showed MN < 3 and NRRT < 100 min, with no seasonal effect, indicating a lower effect of degenerative processes by xenobiotics. The rainy season was more harmful, especially regarding cytogenotoxicity. The use of bioindicator species for environmental monitoring should be guided by an analysis of biomarkers considering the season, because during the period of highest rainfall, biomarkers values can change.
