Authors: Desarrollo Ciencia en 
Published: October 2024

El problema de la utilización de cromo en la industria del cuero para estabilizar la piel animal, está relacionado con los procesos de contaminación asociados, especialmente aquellos referentes con la descarga de aguas a nacimientos de ríos. Esto, debido a su alta toxicidad, sumado a las complicaciones de remoción de este metal pesado desde los líquidos. Debido a su gran área superficial y alta porosidad, los suelos de diatomeas pueden ser una buena alternativa como barrera filtrante en la captura de residuos de cromo. Esta investigación analizó y trató agua contaminada obtenida desde una fábrica curtiembre ubicada en la ciudad de Bogotá. Como material filtrante se utilizaron suelos diatomáceos de Estados Unidos y Colombia. El suelo norteamericano es de tipo multiespecie, mientras que el suelo colombiano se compone únicamente de la especie Aulacoseira Granulata. El medio filtrante consiste en capas de tierra de diatomeas secas, de espesor variable, con y sin activación térmica, instaladas dentro de una cámara presurizada. Como conclusión, todas las probetas arrojaron porcentajes de eliminación de cromo. Los filtros de origen colombiano reportaron una mayor capacidad de remoción de Cr. Se redujo la acidez y la conductividad del agua, respecto de la muestra original.

Published: October 2024

Electrical transformers are a key element in the process of distributing electricity from the producer to the final consumer. The reliability of electrical transformers is ensured through systematic monitoring of the structural condition using chemical analysis of fuel (transformer) oil used for electrical insulation and cooling of transformers. The working life of energy oil and paper insulation can be assessed by evaluating the content of antioxidant additive (ionol) and furan derivatives (furfuryl alcohol, furfural, 2-acetylfuran and 5-methylfurfural). The article provides a critical analysis of methods for measuring ionol and furan derivatives in oils. In particular, it has been established that the most widely used methods for the identification of ionol and furan derivatives are liquid and gas chromatography methods with preliminary isolation of analytes based on the principles of liquid/solid-phase extraction. At the same time, the need for matrix reference materials with established metrological traceability was identified for metrological support of methods for measuring the content of ionol and furan derivatives in oils. Therefore, the purpose of this study was the development of a certified reference material (CRM) for the composition of fuel oil. The technology for producing such a CRM makes it possible to prepare the material with the required concentrations of analytes. The article describes the sequence of preparation of a CRM batch and presents the conclusions of studying the stability and between-bottle homogeneity of the material. The given calculation of the standard uncertainty for the certified value of the CRM from the characterization method, heterogeneity, and instability of the material in accordance with GOST ISO Guide 35–2015 deserves attention. The metrological traceability of certified values of the CRM to the unit of value «mass fraction of a component» reproduced by the State Primary Standard of units of mass (molar) fraction and mass (molar) concentration of organic components in liquid and solid substances and materials based on liquid and gas chromatography-mass spectrometry with isotope dilution and gravimetry (GET 208–2019). The competence of the study is confirmed by the fact that the CRM was recognized as GSO 12232–2023.

Abstract

A disturbed sense of identity is one of the major features of borderline personality disorder (BPD), which manifests early in the course of the disorder, and is potentially examinable using functional imaging during tasks involving self-reflection. Twenty-seven medication-naïve adolescent female patients with BPD, who had no psychiatric comorbidities, and 28 matched healthy female controls underwent fMRI while answering questions about themselves or an acquaintance. Control conditions consisted of answering questions involving factual knowledge and a low-level baseline (cross-fixation). When self-reflection was compared to fact processing, BPD patients exhibited reduced activation in the right dorsolateral prefrontal cortex (DLPFC), as well as in the left parietal and calcarine cortex and the right precuneus. In contrast, other-reflection was associated with relatively lower activation in the medial frontal cortex in BPD patients, with further analysis revealing that this change reflected a failure of de-activation during the fact processing condition. There were no differences between the BPD patients and controls when self- and other-processing was examined against low-level baseline. This study provides evidence of reduced DLPFC activation during self-reflection in adolescent females with BPD, which may reflect diminished top-down cognitive control of this process in the disorder.

Abstract

Cystinuria is the most common genetic cause of urinary stones. Defect in SLC3A1/SLC7A9 genes coding cystine transporter proteins rBAT/b0,+AT will cause Cystinuria. The current work analyzed the clinical and genetics characteristics of Japanese Cystinuria patients. In total, 101 Cystinuria patients were studied. Clinical phenotypes were defined, and genetic analysis of SLC3A1 and SLC7A9 by next-generation sequence was performed. Excretion of urine cystine were determined by twenty-four hours urine analysis. The median age of presentation was 17 years old. In total, 51 different mutant variant alleles were identified (22 and 28 mutant variants in SLC3A1 and SLC7A9, respectively), including 28 novel variants. The p.pro482Leu (c.1445C > T) variant in SCL7A9 was predominantly found in 73 patients. Variants in exon-intron boundaries were identified in 6 cases. The patient with homozygote intron (exon-intron boundary) variant in SCL7A9 presented a severe phenotype with significant loss of mRNA expression. Inclusion of exon and exon-intron boundary variants reduced the number of cases that did not fit autosomal recessive inheritance from 14–9%. Predominance of p.pro482Leu (c.1445C > T) variant in SCL7A9 was a unique characteristic of Japanese Cystinuria. Current data may provide a rationale for the inclusion of exon-intron boundary variants in genomic classification.

Authors: Chu Hongyuan 
Published: October 2024

Abstract

Objective: To report the latest estimates of pediatric neurologic disorders by sex, age, geography and sociodemographic index from 1990 to 2019.
Methods：Thirteen major pediatric neurologic disorders were systematically analyzed by sex, year, age and region according to data from Global Burden of Disease Study 2019. The global burden was calculated based on deaths, prevalence, incidence, and disability-adjusted life-years (DALYs) from 1990 to 2019.
Results: In 2019, global burden of pediatric neurologic diseases was responsible for 14.50% all-cause deaths and 13.82% DALYs in people under 20. The most burdensome diseases were noncommunicable disorders neonatal encephalopathy (DALYs 51.7 million. 95%UI 43.7-61.2), neural tube defects (DALYs 7.6 million. 95%UI 5.6-10.8), migraine (7.1 million, 95%UI 4.5-17.9) and idiopathic epilepsy (4.8 million, 95% UI 3.6-6.5); and communicable disorder meningitis (DALYs 12.5 million, 95%UI 10.2-15.6). Spanned from 1990 to 2019, the absolute number sharply decreased in DALYs (-42.9%) and deaths (-46.9%). Some DALYs could be attributed to risk factors lead exposure, low birth weight and short gestation, particular matter pollution, and alcohol use. Migraine rather than meningitis causes the second most DALYs in countries and territories with middle-, high-middle and high- sociodemographic index (SDI).

Abstract

Bacillus subtilis, a key microorganism in food fermentation, is frequently compromised by phage contamination, which can result in fermentation failures. Therefore, understanding and controlling these phages is critical for enhancing fermentation stability. In this study, we characterize a novel lytic B. subtilis phage, vB_Bsu_hmny2, isolated from sewage collected at a seafood market in Qingdao. This phage features a linear double-stranded DNA genome of 18,762 bp with 25 open reading frames (ORFs), 17 of which are functionally predicted. Transmission electron microscopy reveals a head diameter of 40 ± 10 nm and a short tail length of 20 ± 6 nm. vB_Bsu_hmny2 exhibits stability across various temperatures and pH levels and is classified within the Beecentumtrevirus genus. As a new member of the Beecentumtrevirus, vB_Bsu_hmny2 represents the first phage in this genus to undergo physiological characterization. This research addresses a gap in the functional analysis of similar phages, providing valuable insights for phage control in industrial fermentation processes.

Abstract

Diabetic retinopathy (DR) is a major cause of blindness globally. Neutrophils and neutrophil extracellular traps (NETs) are believed to play a role in the development of DR. However, the specific contribution of NETs to hyperglycemia-induced vascular endothelial cell dysfunction remains unclear. In this study, we cocultured high glucose-activated neutrophils (HGNs) with human umbilical vein endothelial cells (HUVECs) to investigate the role of NETs in high glucose-induced HUVEC dysfunction. Our findings indicate that high glucose levels promote NETs formation, which can be inhibited by a toll-like receptor (TLR) 2 antagonist and a TLR4 antagonist. It was observed that reactive oxygen species production plays a role in TLR2- but not TLR4-mediated NETs formation. Additionally, HGNs were found to promote HUVEC proliferation through phagocytosis rather than NETs. We also discovered that NETs contribute to high glucose-induced HUVEC dysfunction by enhancing neutrophil-HUVEC adhesion, inhibiting HUVEC migration, and compromising the barrier function of the cells by reducing zonula occludens-1 expression. This dysfunction could be partially mitigated by TLR2 and TLR4 antagonists. In conclusion, high glucose stimulates NETs formation, leading to vascular endothelial cell damage, and TLRs may facilitate high glucose-induced endothelial dysfunction by modulating NETs formation.
Highly Accurate 3D Estimation for Occluded Human Pose

Published: October 2024

Abstract

The 3D human pose estimation is crucial in computer vision. It mainly aims at estimating the spatial coordinates of important joints of the human body from monocular images. However, occlusion still is a challenge problem, which hinders their practical applications. To solve this, a novel method based on attention mechanism and distillation learning framework is proposed for unsupervised 3D human pose estimation. Due to the fact that the occluded joints often have multiple motion solutions, a pose filling network based on attention mechanism is proposed to accurately predict the coordinates of the occluded joints. To better establish the relationship between the 3D pose and occluded 2D poses, a distillation learning framework is employed. More precisely, the teacher network uses the complete 2D pose as input, and thus it can produce a more accurate 3D pose. The student network uses occluded 2D pose as the training set and the teacher network output as the target to establish a more robust dependency. Moreover, a simple yet effective data augmentation method is incorporated , which improve the performance by increasing the data diversity. Experimental results of the proposed method achieves PA-MPJPE values 2.3 and 5.2 lower than that of the benchmark method on the Human3.6M and MPI-INF- 3DHP datasets without occlusion, respectively. Moreover, the PA-MPJPE of our method is reduced to 30.3 when 5 out of 17 joints are occluded, comparing to 72.7 of a competitor. The extensive experiments demonstrated the efficiency of proposed method.

Published: October 2024

Abstract

Background: Newcomer populations in urban centers experienced an exacerbated effect of COVID-19 due to their precarious living and working conditions. Addressing their needs requires holistic care provisioning, including psychosocial support, assistance to address food
security, and educational and employment assistance. Intersectoral collaboration between the public and the community sector can reduce vulnerabilities experienced by these groups.
Objective(s): This research explores how community and public sectors collaborated on intersectoral initiatives during the COVID-19 pandemic to support refugees, asylum seekers, and migrants without status in Toronto, Ontario, Canada to generate lessons for a sustainable response.
Methods: The research uses a participatory governance approach to study multiple qualitative cases (a case being an intersectoral initiative). We conducted interviews (n=25) with community and public sector frontline workers and managers, as well as municipal/regional/provincial policymakers and funders. The data was analyzed thematically with an inductive approach.
Findings: The analysis covers four key themes: (1) vulnerable newcomers’ circumstances regarding accessing the social determinants of health during COVID-19; (2) the process of designing specific interventions to target these populations’ needs and service access challenges in the context of COVID-19; (3) the implementation phase of the initiatives, including any associated challenges and lessons learned; and finally, (4) long-term potential sustainability of the initiatives.
Conclusion: The findings demonstrated that intersectoral initiatives can be implemented to develop a responsive service for marginalized populations however, their translation beyond pandemic settings would require institutional mechanisms to bring policy shifts to provide a bottom-up collaborative approach.

Published: October 2024

Obesity poses a substantial health challenge globally, affecting various aspects of reproductive health, including adenomyosis. Adenomyosis, characterized by the presence of endometrial tissue within the myometrium, commonly affects women during their reproductive years, leading to symptoms such as dysmenorrhea and lower urinary tract symptoms (LUTS). This study aimed to investigate the influence of obesity on dysmenorrhea and LUTS severity in adenomyosis patients, considering demographic factors such as age and educational levels as potential moderators. Forty-four adenomyosis patients participated in a cross-sectional study at Dr. Moewardi General Hospital in Surakarta City of Indonesia, between April and September 2023. Diagnosis was confirmed using 2D Transvaginal Ultrasound (2D-TVUS). Obesity was defined using Body Mass Index (BMI) categories, and dysmenorrhea and LUTS were assessed using the Numerical Rating Scale (NRS) and modified International Prostate Symptom Score (IPSS) questionnaire, respectively. Statistical analyses included Pearson correlation. Results indicated a significant positive correlation between obesity and dysmenorrhea (rho = 0.256, P = 0.049) and LUTS (rho = 0.292, P = 0.029). Age and educational level did not significantly moderate these relationships, emphasizing the independent influence of obesity on symptom severity. In conclusion, obesity significantly impacts the severity of dysmenorrhea and LUTS in adenomyosis patients, highlighting the need for tailored management strategies that address both hormonal and inflammatory pathways.
