title: Chemical properties of soils submitted to the application of a bioactivator and basalt and serpentinite powders

description: ABSTRACT Dependence on external raw materials, the high cost of fertilizers, and the search for more sustainable alternatives have encouraged research with remineralizers. This study aimed to evaluate the effect of adding remineralizers associated or not with a bioactivator on pH, H+Al, Al, P, and K in two soils after four incubation times. A completely randomized experimental design was used in a 5 x 2 x 2 x 2 factorial scheme, as follows: doses of remineralizers (0, 2, 4, 8, and 16 Mg ha-1), bioactivator (with and without application), type of remineralizer (basalt and serpentinite), and soil class (Oxisol and Entisol), with four replications. The soils were incubated for 30, 90, 120, and 240 days after the treatment applications. The samples were submitted to pH, Al, H+Al, P, and K analyses at the end of each incubation period. The use of increasing doses of remineralizers favored an increase in pH, P, and K and a reduction in Al and H+Al in the studied soils. Serpentinite powder was more efficient in neutralizing soil acidity, while basalt powder was more efficient in providing P and K to soils. The bioactivator reduced the reaction time of the remineralizers and favored the increase in K availability.

title: Maternal Blood Fatty Acid Levels in Fetal Growth Restriction

description: Abstract Objective: To assess the maternal blood levels of fatty acids (FAs) in pregnancies with fetal growth restriction (FGR). Methods: This prospective cross-sectional study included pregnant women with gestational age between 26 and 37 + 6 weeks with FGR and appropriate for gestational age (AGA) fetuses. The levels of saturated, trans, monounsaturated, and polyunsaturated FAs were measured using centrifugation and liquid chromatography. The Student’s t-test, Mann-Whitney test, and general linear model, with gestational age and maternal weight as covariants, were used to compare FA levels and the FGR and AGA groups. The Chi-square was used to evaluate the association between groups and studied variables. Results: Maternal blood sample was collected from 64 pregnant women, being 24 FGR and 40 AGA. A weak positive correlation was found between the palmitoleic acid level and maternal weight (r = 0.285, p = 0.036). A weak negative correlation was found between the gamma-linoleic acid level and gestational age (r = −0.277, p = 0.026). The median of the elaidic acid level (2.3 vs. 4.7ng/ml, p = 0.045) and gamma-linoleic acid (6.3 vs. 6.6ng/ml, p = 0.024) was significantly lower in the FGR than the AGA group. The palmitoleic acid level was significantly higher in the FGR than AGA group (50.5 vs. 47.6ng/ml, p = 0.033). Conclusion: Pregnant women with FGR had lower elaidic acid and gamma-linoleic acid levels and higher palmitoleic acid levels than AGA fetuses.

title: Association between socioeconomic contextual factor, dental care service availability, and prevalence of periodontitis in Brazil: a multilevel analysis

description: This study aimed to examine the effect of dental care services on periodontitis cases in Brazilian municipalities. The sample comprised 3,426 individuals aged 35-44 years. Moderate to severe periodontitis with clinical attachment loss and probing depth was the dependent variable, both &gt; 3mm. Its exploratory variables were grouped into four categories: (1) individual characteristics; (2) contextual development indicators; (3) health service and structural factors; and (4) dental care use. Data were collected using the SBBrasil 2010 Project, the Brazilian Institute of Geography and Statistics, the Brazilian Information System of Primary and Secondary Care, and the Program to Improve Access and Quality of Dental Specialization Centers (PMAQ-CEO). Multilevel logistic regression was used to assess associations of periodontitis with individual and context variables. Municipalities with &gt; 1 CEO or &gt; 1 of any centers were associated with periodontitis, with OR = 0.97 (95%CI: 0.55-1.71) and OR = 0.41 (95%CI: 0.17-0.97), respectively. Prevalence of periodontitis was more likely in older people, lower education levels, and individuals that sought dental visits for pain/extraction and periodontal treatment. Other dental care services availability were not associated with the prevalence of periodontitis.

title: Supplementary Material for: Characteristics of molecular genetic mutations and their correlation with prognosis in adolescent and adult patients with ALL

description: Introduction: The prognosis of acute lymphoblastic leukemia (ALL) in adolescents and adults is poor, and recurrence is an important cause of their death. Changes of genetic information play a vital role in the pathogenesis and recurrence of ALL; however, the impact of molecular genetic mutations on disease diagnosis and prognosis remains unexplored. This study aimed to explore the frequency spectrum of gene mutations and their prognostic significance, along with the minimal residual disease (MRD) level and hematopoietic stem cell transplantation (HSCT), in adolescent and adult patients aged ≥15 years with ALL. Methods: The basic characteristics, cytogenetics, molecular genetics, MRD level, treatment regimen and survival outcome of patients with untreated ALL (≥15 years) were collected, and the correlation and survival analysis were performed using the SPSS 25.0 and R software. Results: This study included 404 patients, of which 147 were selected for next-generation sequencing (NGS). NGS results revealed that 91.2 % of the patients had at least one mutation, and 67.35% had multiple (≥ 2) mutations. NOTCH1, PHF6, RUNX1, PTEN, JAK3, TET2, and JAK1 were the most common mutations in T-ALL, whereas FAT1, TET2, NARS, KMT2D, FLT3, and RELN were the most common mutations in B-ALL. Correlation analysis revealed the mutation patterns, which were significantly different between T-ALL and B-ALL. In the prognostic analysis of 107 patients with B-ALL, multivariate analysis showed that the number of mutations ≥5 was an independent risk factor for overall survival and the RELN mutation was an independent poor prognostic factor for event-free survival. Discussion: The distribution of gene mutations and the co-occurrence and repulsion of mutant genes in patients with ALL were closely related to the immunophenotype of the patients. The number of mutations ≥5 and the RELN mutation were significantly associated with poor prognosis in adolescent and adult patients with ALL.

title: “Razors always speak louder”: the topic of self-harm in online communities

description: This study aims to understand how Brazilian online communities portray the topic of self-harm, discussing its particularities, the narratives produced, the interactions established, and the purpose of the digital space. It was based on qualitative research in the digital environment from the silent observation of Facebook online communities, which were selected considering the number of participants and their interaction. The observation followed a previous script and posts were recorded by screenshots. Publications were organized in the following categories: characterization and functioning of the community; self-directed violence (self-harm and suicide); motivations for the act; strategies to prevent the act; and loving experience. Results showed that the communities were positively guided and defended self-harm without any regulation, which guaranteed the free expression of their participants and detailed reports describing the methods and objects used, the level of efficiency, and how to hide the wounds. Although participants shared the fear of being discovered, they published images of their own scars and wounds, materializing discourses of suffering on the Internet and glamorizing the cuts, the feeling of pleasure, and the sense of belonging, since they are also identity marks. Our findings show that young people who harm themselves share their suffering experiences with other young people without the mediation of a professional, therefore, considering its possible effects on mental health is necessary.

title: DEVELOPING DYNAMIC CAPABILITY IN SOCIAL STRATEGIES

description: ABSTRACT This paper aims to understand how firms develop a dynamic capability to implement social strategies and manage pressures from local and global stakeholders. A multiple case study was conducted with four Brazilian multinationals in the pulp and paper industry. These firms develop dynamic capabilities to adapt to a changing environment by monitoring it and learning from their stakeholders, nurturing mutually beneficial relationships and partnerships with other organizations, and constantly adopting or influencing social strategies. This paper’s findings extend the literature that converges social strategies and dynamic capabilities by presenting evidence that these firms are developing and deploying a dynamic capability to implement social strategies. The findings also show that firms can develop complex and dynamic capabilities to manage stakeholder demands at local and global levels. Finally, this paper contributes to the dynamic capability and social strategy literature by demonstrating that such capability is critical in managing multiple stakeholders.

title: Adaptive Hybrid Precoding Strategy for Cell-Free Massive MIMO

description: Abstract This work presents an adaptive hybrid signal precoding strategy for Cell-Free (CF) Massive multiple-input multiple-output (MIMO) systems. The proposed solution exploits the advantages of both distributed and centralized signal processing schemes to perform precoding. In our proposal, some access points (APs) are dynamically configured to be used in a centralized precoding scheme, whereas others are adjusted to employ a distributed method. Simulation results show that it is possible to achieve a good compromise between spectral efficiency (SE) and computational complexity (CC) in CF Massive MIMO systems finding a sensible balance between APs utilized in centralized and distributed precoding. To the best of our knowledge, prior-art solutions have not addressed an adaptive hybrid precoding method itself, they have only proposed a specific solution for each architecture, i.e., distributed or centralized.

title: MassIVE MSV000092396 - ProteasomeID: quantitative mapping of proteasome interactomes and substrates for in vitro and in vivo studies
title: Proteasomes are essential molecular machines responsible for the degradation of proteins in eukaryotic cells. Altered proteasome activity has been linked to neurodegeneration, auto-immune disorders and cancer. Despite the relevance for human disease and drug development, no method currently exists to monitor proteasome composition and interactions in vivo in animal models. To fill this gap, we developed a strategy based on tagging of proteasomes with promiscuous biotin ligases and generated a new mouse model enabling the quantification of proteasome interactions by mass spectrometry. We show that biotin ligases can be incorporated in fully assembled proteasomes without negative impact on their activity. We demonstrate the utility of our method by identifying novel proteasome-interacting proteins, charting interactomes across mouse organs, and showing that proximity-labeling enables the identification of both endogenous and small molecule-induced proteasome substrates.

title: Obesity and diet contents of protein and fat are associated with underreport of energy at pregnancy

description: Abstract Objectives: to evaluate the association of pre-pregnancy and current body mass index and the density of dietary macronutrients on underreporting of energy intake at pregnancy. Methods: cross-sectional analysis of 327 postpartum women from the city of Mesquita, in Rio de Janeiro. A food frequency questionnaire was administered at maternity ward having the last six months of the pregnancy as the time frame. Energy balance was considered as the outcome, and it was calculated as the division of energy intake by basal metabolic rate (underreport &lt;1.35). Multivariate logistic regression was applied to test the associations between body mass index (pre-gestational and postpartum) on energy balance (underreport or not). Dietary density of protein (4th quartile), carbohydrate (1st quartile) and fat intake (1st quartile) were tested. Results: mean energy intake was 2,894 kcal and near of 25% of the women were considered as underreported during pregnancy. Obese women had higher chance (OR=1.90; CI95%=1.09-3.33) of being underreported at pregnancy. Underreported women presented greater chance of report dietary intake with higher contents of protein (OR=2.37; CI95%=1.37-4.09) and lower density of fat (OR= .81; CI95%=1.04-3.15). Conclusion: underreported pregnant women had higher chance of report great and lower amounts of protein and fat dietary densities.
