ABSTRACT

Ukraine's tug-of-war between Russia and the West has had significant and lasting consequences for the country. In 2013, Viktor Yanukovych, the Ukrainian president aligned with Russia, opted against signing an association agreement with the European Union. This agreement aimed to facilitate trade and travel between the EU and Ukraine. This decision sparked widespread protests that coalesced in Kyiv's Maidan Square, eventually becoming known as the Euromaidan protests. In this study, we analyze the protest data from 2013, sourced from Ukraine's Center for Social and Labor Research. Despite the dataset's limitations and occasional inconsistencies, we demonstrate the extraction of valuable insights and the construction of a descriptive model from such data. Our investigation reveals a pre-existing state of self-excitation within the system even before the onset of the Euromaidan protests. This self-excitation intensified during the Euromaidan protests. A statistical analysis indicates that the government's utilization of force correlates with increased future protests, exacerbating rather than quelling the protest movement. Furthermore, we introduce the implementation of Hawkes process models to comprehend the spatiotemporal dynamics of the protest activity. Our findings highlight that, while protest activities spread across the entire country, the driving force behind the dynamics of these protests was the level of activity in Kyiv. Furthermore, in contrast to prior research that emphasized geographical proximity as a key predictor of event propagation, our study illustrates that the political alignment among oblasts, which are the distinct municipalities comprising Ukraine, had a more profound impact than mere geographic distance. This underscores the significance of social and cultural factors in molding the trajectory of political movements.

ABSTRACT

A protocol for the analysis of a binary system comprising polyacrylamide hydrogel-attached sperm cells using high-vacuum scanning electron microscopy (SEM) is presented. This protocol focuses on optimizing the SEM procedure to obtain accurate and detailed imaging of the sperm cells and their interactions with the hydrogel scaffold. The methodology involves a stepwise sample preparation, including sample dehydration through a gradual exchange of ethanol/water ratios, followed by the application of a conductive metal coating. By employing this modified protocol, the traditional use of acetone dehydration, which may introduce chemical alterations to the materials, is avoided. The proposed approach enables a comprehensive evaluation of the morphology and interactions within the biological system in contact with the soft material scaffold. Furthermore, the potential application of this protocol extends to the study of other mammalian reproductive cells or cells of different origins adhered to hydrogel scaffolds. RESEARCH HIGHLIGHTS: Novel SEM protocol reveals precise imaging of sperm-hydrogel attachment in a binary system, enhancing our understanding of cell-material interactions. By optimizing SEM procedures, the protocol achieves precise imaging of sperm-hydrogel interactions using ethanol/water dehydration and a conductive metal coating. This modified approach enables a thorough assessment of morphology and interactions in the binary system,extending its potential applicability to other reproductive cells on hydrogelscaffolds.

ABSTRACT

Physiological stress during injury and surgery negatively impacts protein balance and muscle mass maintenance. Adequate perioperative protein intake may attenuate muscle atrophy to maintain and facilitate functional recovery, particularly in older adults; yet, screening tools routinely used in clinical settings do not specifically assess protein intake when assessing nutrition risk. Although assessing malnutrition is a priority, suboptimal protein intake in non-malnourished patients should also be identified given protein's critical role in muscle health. This opinion paper highlights the potential for using a clinically appropriate protein-focused screener for rapid and efficient characterization of protein intake.

ABSTRACT

Glyphosate is a systemic, non-selective, pre and post-emergence wide range herbicide. In 2015, IARC classified Glyphosate as "a probable carcinogenic agent for humans". The aim of this study was to evaluate the cytotoxicity and genotoxicity of the commercial formulation of glyphosate (Roundup® Control Max) at environmentally relevant concentrations and measure the potential effect of this herbicide over the cell capacity to repair DNA damage. HEK293 cells were exposed to 5 concentrations of Roundup® Control Max equivalent to 0.7; 7; 70; 700 and 3,500 µg/L glyphosate acid, for 1, 4 and 24 h. Cytotoxicity was quantified by the Trypan Blue staining method and by the MTT assay, while genotoxicity and evaluation of DNA damage repair kinetics were analyzed through the alkaline comet assay. In all treatments, cell viability was higher than 80%. The three highest glyphosate concentrations-70 µg/L, 700 µg/L, and 3,500 µg/L-increased levels of DNA damage compared to the control at the three exposure times tested. Finally, concerning the kinetics of DNA damage repair, cells initially exposed to 3,500 µg/L of glyphosate for 24 h were unable to repair the breaks in DNA strands even after 4 h of incubation in culture medium. The present study demonstrated for the first time that Roundup® Control Max may induce genetic damage and cause alterations in the DNA repair system in human embryonic kidney cells even at concentrations found in blood and breast milk of people exposed through residues of the herbicide in food, which values have been poorly assessed or not studied yet according to the existent literature.

ABSTRACT

OBJECTIVE: To assess change in attitudes toward women who have experienced trauma and to describe interns' reflections regarding the provision of universal trauma precautions and the training sessions. METHODS: Dietetic interns participated in 3 2-hour trauma-informed care (TIC) training sessions. A multiple-methods design was used, incorporating a presurvey and postsurvey to assess change in attitudes and thematic analysis to assess self-reflections. RESULTS: The attitudes of the interns improved across all statements. Two components measuring attitudes about sympathetic feelings toward mothers with underlying trauma and substance use disorder during pregnancy and retaining custody of their children reached statistical significance (P < 0.05). Four themes were identified in the self-reflections: TIC training was informative, valuable, and warranted, and interns felt comfortable discussing TIC. CONCLUSIONS AND IMPLICATIONS: Students positively assessed the TIC training and changed their attitudes. Trauma-informed care can be effectively incorporated within dietetics education to support students in developing therapeutic relationships in their future nutrition care standards.

ABSTRACT

Novel soft materials based on hydrogel are proposed to enhance the selection of high-quality stallion sperm based on their adhesion capacity. The hydrogel surfaces are derived from polyacrylamide (PAAm), which is copolymerized with neutral and ionic co-monomers to modify the interfacial properties. The hydrogels undergo characterization through FTIR spectroscopy, assessment of swelling capacity, and wettability under various experimental conditions. Sperm adhesion capacity on the hydrogels is examined through several parameters including the percentage of bound sperm (%Sp) to hydrogels, tail oscillation intensity and flagellar movement. The biointerfacial properties of sperm-hydrogel systems vary based on the chemical composition of hydrogel as well as the components present in the culture medium. High %Sp and excellent metabolic activity of the spermatozoa are observed on hydrogel surfaces that possess moderate hydrophilicity. Specifically, a cationic hydrogel in BGM3 culture medium and a neutral surface in BGM3 medium supplemented with BSA exhibit favorable outcomes. Scanning Electron Microscopy (SEM) reveals the normal morphology of the head and tail in spermatozoa adhered to the hydrogel. Therefore, these hydrogel surfaces are potential materials for selecting stallion sperm with high quality, and their application could be extended to the study of other mammalian reproductive cells.

ABSTRACT

In industrial applications based on texture classification, efficient and fast classifiers are extremely useful for quality control of industrial processes. The classifier of texture images has to satisfy two requirements: It must be efficient and fast. In this work, a texture unit is coded in parallel, and using observation windows larger than 3×3, a new texture spectrum called Texture Spectrum based on the Parallel Encoded Texture Unit (TS_PETU) is proposed, calculated, and used as a characteristic vector in a multi-class classifier, and then two image databases are classified. The first database contains images from the company Interceramic®® and the images were acquired under controlled conditions, and the second database contains tree stems and the images were acquired in natural environments. Based on our experimental results, the TS_PETU satisfied both requirements (efficiency and speed), was developed for binary images, and had high efficiency, and its compute time could be reduced by applying parallel coding concepts. The classification efficiency increased by using larger observational windows, and this one was selected based on the window size. Since the TS_PETU had high efficiency for Interceramic®® tile classification, we consider that the proposed technique has significant industrial applications.

ABSTRACT

Introducción: la acrilamida se forma mediante la reacción de Maillard, por lo que se encuentra en muchos productos alimenticios sometidos a procesos térmicos, generando genotoxicidad y daños al ADN. Los estudios han reportado que los lactobacilos tienen la capacidad de generar compuestos con actividad antioxidante, antigenotóxica y antimutagénica, y es por esto que el presente trabajo pretende evaluar el efecto de cepas de Lactobacillus y sus extractos intra y extracelulares contra la genotoxicidad y el estrés oxidativo causado por la acrilamida. Métodos: se empleó una cepa de Lactobacillus casei Shirota y una cepa de Lactobacillus reuteri NRRL B-14171. Ambas fueron cultivadas en caldo MRS y sometidas a tratamientos mecánicos y enzimáticos para obtener los extractos extra e intracelulares. Los linfocitos fueron cultivados en medio RPMI, la peroxidación lipídica se evaluó por TBARS y la capacidad antioxidante se midió en los extractos extra e intracelulares con la técnica ABTS, empleando además una cepa de Saccharomyces cerevisiae RC 212 como modelo. La reducción de la peroxidación lipídica en los linfocitos se midió por TBARS y la reducción de la genotoxicidad mediante la reducción de la formación de micronúcleos en los linfocitos. Resultados: ambas cepas evaluadas, así como sus extractos intra y extracelulares, mostraron capacidad de contrarrestar el estrés oxidativo y la genotoxicidad causada por la acrilamida. Conclusión: los resultados encontrados, sugieren que el empleo de extractos intra y extracelulares de ambas cepas podría ser una alternativa para reducir los efectos de genotoxicidad y estrés oxidativo causados por la acrilamida sin la necesidad de requerir una estructura viable.(AU)

ABSTRACT

Machine learning methods are becoming increasingly popular to anticipate critical risks in patients under surveillance reducing the burden on caregivers. In this paper, we propose an original modeling that benefits of recent developments in Graph Convolutional Networks: a patient's journey is seen as a graph, where each node is an event and temporal proximities are represented by weighted directed edges. We evaluated this model to predict death at 24 hours on a real dataset and successfully compared our results with the state of the art.

ABSTRACT

It is well known that relocation strategies in ecology can make the difference between extinction and persistence. We consider a reaction-advection-diffusion framework to analyze movement strategies in the context of species which are subject to a strong Allee effect. The movement strategies we consider are a combination of random Brownian motion and directed movement through the use of an environmental signal. We prove that a population can overcome the strong Allee effect when the signals are super-harmonic. In other words, an initially small population can survive in the long term if they aggregate sufficiently fast. A sharp result is provided for a specific signal that can be related to the Fokker-Planck equation for the Orstein-Uhlenbeck process. We also explore the case of pure diffusion and pure aggregation and discuss their benefits and drawbacks, making the case for a suitable combination of the two as a better strategy.

ABSTRACT

Dementia is a multifactorial disease in which environmental, lifestyle, and genetic factors intervene. Population studies have been used in looking for the susceptibility genes for this disease. Since the activity of dopamine b hydroxylase (DßH) is reduced in the hippocampus and neocortex in the brain, changes in the physiological status of dopamine have been reported in Alzheimer's disease (AD) induced by this enzyme. Therefore, DBH polymorphisms have been associated with susceptibility to some neurological diseases such as AD, but few studies have investigated the relationship between these polymorphisms with other types of dementia, especially in Mexican populations. The aim of this study was to evaluate the association between single-nucleotide polymorphism (SNP) in the dopamine b-hydroxylase (DBH gene (rs1611115) and their interactions with environmental factors and the dementia risk. We examined the genotype of the gene DBH (rs1611115) polymorphism in patients with dementia and healthy. The interaction and the impact of DBH (rs1611115) polymorphism on dementia were examined through multifactor dimensionality reduction (MDR) analysis, and the results were verified by the Chi-square test. Hardy-Weinberg equilibrium (HWE) was also checked by the Chi-square test. The relative risk was expressed by odds ratio (OR) and 95%. A total of 221 dementia patients and 534 controls met the inclusion criteria of MDR analyses. The results of the MDR analysis showed that the development of dementia was positively correlated with interaction between the TT genotype of the DBH1 locus rs1611115 TT and diabetes, hypertension, and alcohol consumption (OR = 6.5: 95% CI = 4.5-9.5), originating further cognitive damage. These findings provide insight into the positive correlation between the metabolism and cardiovascular disorders and the presence of the T allele by means of a recessive model of DBH rs1611115 polymorphism with the suspensibility of dementia.

ABSTRACT

This systematic meta-review evaluated the effects of exercise with and without protein interventions on muscle strength and function in older adults with sarcopenic obesity. PubMed, Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health Literature, Scopus, and SPORTDiscus databases were searched through February 2021 for relevant systematic reviews and meta-analyses with aerobic, resistance, and/or combined training interventions with and without protein supplementation in older adults ≥ 65 years with sarcopenic obesity. This meta-review showed that exercise with and without protein supplementation improved body composition (i.e., decreased percentage body fat) and functional outcomes (i.e., gait speed and grip strength). Because the current literature is limited, determining the effects of exercise and combined protein supplementation in this population requires further investigation. In the meantime, protein recommendations should align with general sarcopenia recommendations. Based upon available findings, tentative exercise recommendations to optimize health outcomes in this population are proposed.

ABSTRACT

OBJECTIVE: To determine if oropharyngeal therapy with mother's own milk (OPT-MOM) reduces late-onset sepsis (L-OS; primary outcome), NEC, death, length of stay, time to full enteral nutrition (FEN) and full oral feeds in preterm infants (BW < 1250 g). DESIGN: Infants (N = 220) were randomized to Group A (milk) or B (placebo) and received 0.2 mL every 2 h for 48 h, then every 3 h until 32 weeks CGA. RESULTS: There were no significant differences in L-OS, NEC or death. Group A trended towards an 8-day reduction in stay, 8-day reduction in time to FEN and a 6-day reduction in time to full oral feeds, compared to B. While clinically relevant, due to large variability in outcomes and lack of power, p values were > 0.05. CONCLUSION: OPT-MOM did not reduce L-OS, NEC or death. Group A trended towards a reduced stay and better nutritional outcomes, but results were not statistically significant. CLINICALTRIALS: GOV: NCT02116699.

ABSTRACT

Childhood obesity is a national epidemic, and many efforts have been made to understand its risk factors. The purpose of this review was to provide an updated account of the observational studies evaluating the relationship between 100% fruit juice intake and obesity in children and adolescents, and to highlight the major risk factors that may impact this relationship. PubMed and Scopus were searched for terms related to fruit juice and childhood obesity, and studies assessing 100% fruit juice intake in participants ≤ 19 years old, with obesity-related outcomes (BMI or adiposity), and published before March 9, 2021 were included. There were 17 prospective cohort and 14 cross-sectional studies included in the analysis. Overall, the evidence does not support a relationship between 100% fruit juice intake and measures of obesity in most children. There is some evidence to suggest a minor positive association in some overweight or very young children, but due to fundamental differences and limitations in methodology, further investigation is required. Significant gaps in literature on this topic exist particularly in regards to randomized clinical trials in children, and in studies in racially diverse populations.

ABSTRACT

Objective: Evidence supports the important role of neuroinflammation in some types of dementia. This study aimed to evaluate the effect of epistasis of gene cytokines such as interleukin (IL)-α, IL-6, tumor necrosis factor (TNFα), and interferon-gamma (IFN-γ) on the susceptibility to the development of dementia. Materials and methods: In the study, 221 patients diagnosed with dementia and 710 controls were included. The multifactor-dimensionality reduction (MDR) analysis was performed to identify the epistasis between SNP located in genes of IL-α (rs1800587), IL-6 (rs1800796), TNFα (rs361525 and rs1800629), and IFNγ (rs2069705). The best risk prediction model was identified based on precision and cross-validation consistency. Results: Multifactor-dimensionality reduction analysis detected a significant model with the genes TNFα, IFNγ, IL1α, and IL6 (prediction success: 72%, p < 0.0001). When risk factors were analyzed with these polymorphisms, the model achieved a similar prediction for dementia as the genes-only model. Conclusion: These data indicate that gene-gene interactions form significant models to identify populations susceptible to dementia.

ABSTRACT

The present study evaluated the risk effect of 12 Single Nucleotide Polymorphisms in the SORL1 gene in the Mexican population using Late-Onset Alzheimer's Disease (LOAD) and control subjects. Considering APOE as the strongest genetic risk factor for LOAD, we conducted interaction analyses between single nucleotide polymorphisms (SNPs) and the APOE genotype. METHODS: Patients were interviewed during their scheduled visits at neurologic and geriatric clinics from different institutions. The LOAD diagnosis included neurological, geriatric, and psychiatric examinations, as well as the medical history and neuroimaging. Polymorphisms in SORL1 were genotyped by real-time PCR in 156 subjects with LOAD and 221 controls. APOE genotype was determined in each study subject. Allelic, genotypic, and haplotypic frequencies were analyzed; an ancestry analysis was also performed. RESULTS: The A/A genotype in rs1784933 might be associated with an increased LOAD risk. Two blocks with high degree linkage disequilibrium (LD) were identified. The first block composed by the genetic variants rs668387, rs689021 and rs641120 showed a positive interaction (mainly the rs689021) with rs1784933 polymorphism. Moreover, we found a significant association between the APOE ε4 allele carriers and the variant rs2070045 located in the second LD block. CONCLUSION: The rs1784933 polymorphism is associated with LOAD in Mexican patients. In addition, the presence of APOE ε4 allele and SORL1 variants could represent a genetic interaction effect that favors LOAD risk in the Mexican population. SNPs have been proposed as genetic markers associated with the development of LOAD that can support the clinical diagnosis. Future molecular studies could help understand sporadic Alzheimer's Disease (AD) among the Mexican population, where currently there is a sub-estimate number in terms of disease frequency and incidence.

ABSTRACT

Increasing dietary protein intake during periods of muscle disuse may mitigate the resulting decline in muscle protein synthesis (MPS). The purpose of this randomized pilot study was to determine the effect of increased protein intake during periods of disuse before anterior cruciate ligament (ACL) reconstruction on myofibrillar protein synthesis (MyoPS), and proteolytic and myogenic gene expression. Six healthy, young males (30 ± 9 y) were randomized to consume a high-quality, optimal protein diet (OP; 1.9 g·kg−1·d−1) or adequate protein diet (AP; 1.2 g·kg−1·d−1) for two weeks before ACL reconstruction. Muscle biopsies collected during surgery were used to measure integrated MyoPS during the intervention (via daily deuterium oxide ingestion) and gene expression at the time of surgery. MyoPS tended to be higher, with a large effect size in OP compared to AP (0.71 ± 0.1 and 0.54 ± 0.1%·d−1; p = 0.076; g = 1.56). Markers of proteolysis and myogenesis were not different between groups (p > 0.05); however, participants with greater MyoPS exhibited lower levels of MuRF1 gene expression compared to those with lower MyoPS (r = −0.82, p = 0.047). The data from this pilot study reveal a potential stimulatory effect of increased daily protein intake on MyoPS during injury-mediated disuse conditions that warrants further investigation.
