Differentiation of Human Dental Pulp Stem Cells
Authors: Zhang Jian , Wu Jiankun , Lin Xiuya , Liu Xueli
Published: July 2022

Background:

Pulp regeneration is a promising strategy that promotes the continued development of young permanent teeth with immature apical foramen. Platelet-rich fibrin (PRF) was found to stimulate the proliferation and differentiation of osteoblasts, but its effects on osteoblast/odontoblast differentiation of human dental pulp stem cells (hDPSCs) is unknown.

Methods:

The hDPSCs were isolated and identified by flow cytometry using surface known markers. The CCK-8 assay and the expression of Ki67 and PCNA were used to examine hDPSC proliferation. After 7 days culture in osteo-/odontoblastic induction medium with various concentrations of liquid PRF (0, 10% and 20%), the marker of the early stage of osteogenesis-intracellular alkaline phosphatase (ALP) was checked. After 21 days culture, matrix mineralization was checked using Alizarin Red S and quantified. The mRNA and protein levels of osteo-/odontoblastic genes including RUNX2, DSPP, DMP1 and BSP were measured by qRT-PCR. Notch signal was checked by Western blot to analyze three key proteins (Notch 1, Jagged 1 and Hes 1).

Results:

PRF-treated groups showed higher expression of Ki-67 and PCNA, higher ALP activity, and the higher dose showed a stronger induction. PRF promoted osteo-/odontoblastic differentiation of hDPSCs indicated by elevated protein levels and mRNA levels of the expression of osteo-/odontoblastic markers. The three key proteins in Notch signaling all showed an increase compared with the control group, and increased as the PRF concentration became higher.

Conclusion:

PRF can promote the proliferation and osteo-/odontoblastic differentiation of hDPSC, which may be through the Notch signaling pathway.

Published: July 2022

Background:

The syndrome Klinefelter syndrome (KS) is a genetic disorder due to an
extra X chromosome in males. Many cases remain undiagnosed until the onset of major manifestations,
which include hypergonadotropic hypogonadism and infertility. This condition is associated
with many comorbidities that involve the cardiovascular, endocrine, and immune systems.
Last but not the least, individuals with KS show a high risk of developing psychiatric and mood
disorders in adult age.

Objective:

While many studies are accessible on KS in adult individuals, the neuroinflammatory
condition in adolescent and prepubertal KS individuals is not fully known.

Methods:

Our study aims to evaluate in prepubertal and adolescent KS individuals, for the first
time, the levels of the serum of brain-derived neurotrophic factor (BDNF), nerve growth factor
(NGF), cytokines having subtle roles in oxidative processes, and neuroinflammation with respect
to the levels of TNF-α, TGF-β, MCP-1, IL-1α, IL-2, IL-6, IL-10, and IL-12 and oxidative stress
by employing free oxygen radicals defense and free oxygen radicals test.

Results:

We found no changes in NGF and oxidative stress parameters, but BDNF decreased compared
to healthy children. Quite interestingly, our data showed reduced levels of IL-2, IL-1α, IL-
12, IL-10, and IL-6 in prepubertal KS children.

Conclusion:

The present study discloses disrupted immune system and neurotrophin pathways in
KS children.

Associated with Photovoltaic Applications
Authors: Supriya J. , Rajashekar J.S.
Published: July 2022

Environmentally friendly renewable energy sources showed substantial development over the most recent couple of years. Compared with other RES, extracting power from solar has become the most beneficial and profitable source because of its environmental friendly nature. In the process of extraction of power, DC-DC converters has given conspicuous interest due to their broad use in various applications. Although a lot of advancements, research work, and continuous tuning of circuits of photovoltaic systems, still remarkable efficiency and stability has not been achieved yet. In this paper, exhaustive research and development of DC-DC converters are identified and studied. It surveys the difficulties associated with implementing new converter topologies in photovoltaic applications. Presented new topologies that have simpler control, less number of components, economical, and suitable for solar applications. Various types of isolated converter are explained such as different bidirectional converters, high step- up converters, zero current switching, high frequency isolated converter, isolated converter with discontinuous input, quasi-Z-source converter, multiport converter, high efficient converter, single-switch converter and single-switch resonant converter. Different types of structure characteristics and operation of the converters are presented. Based on the distinct features, a comparison of the converters has been carried out. From the review, a single converter topology does not fulfill all requirements in the industry. Future scopes of the research trend are suggested. The current survey is to update the research carried out during the time gap.
The Effect of Modifying TiO2 with Lanthanides on the Photocatalytic
Degradation of Ciprofloxacin, A Hydrophobic Compound
Authors: Paz Yaron , Toker Omri , Krysa Josef
Published: July 2022

Background:

Recent years have seen the increased use of antibiotics and hormones in domestic, agricultural and healthcare applications. As a result, waste streams contain more and more of
these compounds, which eventually end up in the environment, where they might cause serious damage to flora and fauna, even in miniscule amounts. This issue is currently not resolved by conventional
waste treatment plants, as their adequacy for handling these compounds, many of which are non-polar,
is quite limited.

Objective:

This work studies the effect of modifying the hydrophilic photocatalyst TiO2 with various
rare earth oxides (REOs), of the lanthanide family (Er, La, Gd, Ce), on the photocatalytic activity toward degrading non-polar compounds. Ciprofloxacin, a widely used antibiotic, was chosen as a model
hydrophobic compound. Its degradation rate was compared with that of caffeine, used as a model hydrophilic compound.

Methods:

Fused silica plates were coated with REO-containing films comprising TiO2 and silica. The
latter was used as a binder to assure high integrity and strong adherence of the films to their substrates. The plates were characterized by SEM, EDS, XPS, and scratch-resistance measurements. The
photocatalytic kinetics were determined with UV-Vis spectroscopy (caffeine) or fluorescence spectroscopy (ciprofloxacin). Further information was obtained by measuring the kinetics in the presence
of charge scavengers and by SEM-EDS mapping of the surface following photodeposition of platinum.

Results:

Most REOs-modified TiO2 coatings showed increased activity and selectivity towards ciprofloxacin compared to coatings that did not contain REOs. A study on the silica binder's role suggests
that the binder's hydrophobicity plays an important role in promoting ciprofloxacin degradation. With
respect to REOs contribution, SEM-EDS mapping of REOs-containing films indicated that the REOs
act as electron sinks, despite the position of their conduction bands. This charge accumulation is likely
responsible for the contribution of the REOs to the enhanced degradation of ciprofloxacin. The hydrophobicity of lanthanide oxides, while affecting the adsorption of the non-polar ciprofloxacin, cannot
explain the observed effects.

Conclusion:

Oxides of erbium, gadolinium and lanthanum may be used to increase photocatalytic
rates via electron accumulation, despite the location of their conduction bands. This is in parallel to
their effect as adsorption promotors of hydrophobic compounds

Authors:   Faculty of Business Administration, Dai Nam University, Hanoi, Vietnam, et al. Thao
Published: July 2022

This study provides new evidence on the relationship between leadership style, job stress, and the intention to leave of employees in supply enterprises in Vietnam in the context of the COVID-19 epidemic. Unlike most previous studies, the results of this study found that the level of work stress of employees is quite high (4.03 points) and is positively affected by the transactional leadership style, while that of transformational leadership style will reduce stress levels. The study also found that, although the level of work stress was high, the intention to quit was quite low; the older the workers, the lower the intention to quit; and women have a higher intention to quit than men. However, this study has many limitations when it does not consider factors affecting work stress and intention to leave other jobs such as job satisfaction, working environment, etc. Research results provide a theoretical and practical basis for leaders at supply enterprises in adjusting human resource management policies to reduce stress for employees and enhance long-term commitment. with the company.

Madurez de la deuda corporativa como variable de tiempo: evidencia de las empresas públicas de México
Authors: Farfán Pérez Lianet , Moreno Jorge O. , Mercedes Adamuz María de las
Published: July 2022

El objetivo de esta investigación es identificar los determinantes de la madurez de la deuda para las empresas mexicanas que cotizan en la BMV, usando una definición alternativa de esta variable dependiente. En particular, se define la madurez como “tiempo para expiración del contrato” considerando el promedio ponderado del tiempo a vencimiento, contribución original del presente trabajo. Se utilizan modelos de datos panel y de selección de Heckman, pues el uso de datos longitudinales en un panel desbalanceado puede presentar problemas de selección en forma de atrición. Los resultados sugieren que el sesgo por atrición es significativo, y que la madurez promedio de la deuda está determinada por variables como tamaño y apalancamiento, entre otras característias de las empresas, así como la tasa de interés del mercado. Como principal limitación, se tienen las omisiones de datos de las fuentes de información utilizadas generando un panel corto y desbalanceado. Se concluye que al usar este método de medición de madurez se obtienen mejores resultados para analizar el plazo de vencimiento de la deuda, comparado con las métricas tradicionales en la literatura.

The Association Between COVID-19 Information Sources and Stigma Against Health Care Workers Among College Students: Cross-sectional, Observational Study
Authors: Nakanishi Miharu , Sakai Mai , Takagi Gen , Toshi Keita , Wakashima Koubun , Yoshii Hatsumi
Published: July 2022

Background

The COVID-19 pandemic has triggered stigmatic attitudes against health care workers. Some forms of social media may play a role in disseminating stigmatizing messages.

Objective

We aimed to investigate the association between COVID-19 information sources and stigma against health care workers among college students during the pandemic.

Methods

A cross-sectional, observational study was conducted using a web-based platform in the Tohoku region of Japan. College students aged ≥20 years were asked to complete the questionnaire between August 18 and October 31, 2020. Stigma against health care workers was evaluated using a modified Japanese version of the Social Distance Scale. Participants were also asked to rate their perceived vulnerability to infection using the Japanese version of the Perceived Vulnerability to Disease scale.

Results

A total of 281 students from 8 colleges completed the web-based survey. There were 139 (49.5%) participants who used Twitter, 187 (66.5%) who used news websites, and 46 (16.4%) who used the websites of public health agencies as COVID-19 information sources. After adjusting for age, sex, department, and Perceived Vulnerability to Disease scores, the level of stigma did not differ between students who used Twitter and those who did not. Students who used the websites of public health agencies showed a significantly less stigmatic attitude than those who did not.

Conclusions

Fact-checking and directing visitors to credible information sources from public health agencies may have prevented the formation of stigmatic attitudes toward health care workers. An effective strategy to enable easy access to information provided by public agencies should be integrated into widespread web-based platforms.

Published: July 2022

Background

Family health history has been recognized as an essential factor for cancer risk assessment and is an integral part of many cancer screening guidelines, including genetic testing for personalized clinical management strategies. However, manually identifying eligible candidates for genetic testing is labor intensive.

Objective

The aim of this study was to develop a natural language processing (NLP) pipeline and assess its contribution to identifying patients who meet genetic testing criteria for hereditary cancers based on family health history data in the electronic health record (EHR). We compared an algorithm that uses structured data alone with structured data augmented using NLP.

Methods

Algorithms were developed based on the National Comprehensive Cancer Network (NCCN) guidelines for genetic testing for hereditary breast, ovarian, pancreatic, and colorectal cancers. The NLP-augmented algorithm uses both structured family health history data and the associated unstructured free-text comments. The algorithms were compared with a reference standard of 100 patients with a family health history in the EHR.

Results

Regarding identifying the reference standard patients meeting the NCCN criteria, the NLP-augmented algorithm compared with the structured data algorithm yielded a significantly higher recall of 0.95 (95% CI 0.9-0.99) versus 0.29 (95% CI 0.19-0.40) and a precision of 0.99 (95% CI 0.96-1.00) versus 0.81 (95% CI 0.65-0.95). On the whole data set, the NLP-augmented algorithm extracted 33.6% more entities, resulting in 53.8% more patients meeting the NCCN criteria.

Conclusions

Compared with the structured data algorithm, the NLP-augmented algorithm based on both structured and unstructured family health history data in the EHR increased the number of patients identified as meeting the NCCN criteria for genetic testing for hereditary breast or ovarian and colorectal cancers.

Food presents as a vital necessity, necessary for the conservation of life and well-being of individuals. This process is considered a basic requirement for health promotion, contributing to human growth and development with quality. Healthy food is one that keeps the body in a state of health, when it prioritizes adequate food, in quantities and quality, at the right times, and that contains varied nutrients to achieve satisfactory benefits for the health of the body and thus contribute to the acquisition of quality of life (BUSATO et al., 2021). The objective of this work was to discuss the main factors associated with Food Consumption and Nutritional Status of schoolchildren, based on a critical review on the subject. To review the topic, the following databases were consulted: BIREME and CAPES journal, covering the period from 2018 to 2021. The descriptors used in the search were: "food consumption", "nutritional assessment", "nutritional status," " school” and “school health”. The research results indicate, through the analysis of the scientific literature, a low consumption of in natura and healthy foods among schoolchildren, in addition to the high consumption of processed and ultra-processed foods, resulting in changes in the nutritional status and consequently in the health of the investigated population, with the presence of overweight and obesity, dyslipidemia and increased blood glucose, predisposing factors for cardiovascular diseases. Thus emphasizing the importance of the debate on the subject in future research.

Contaminated surfaces increase the risk of hospital infections. Traditional hospital cleanliness monitoring has become insufficient. ATP bioluminescence is a developed monitoring tool with limited clinical data in healthcare settings. Therefore, the current work aims to study the impact of the ATP monitoring tool on wound infection rates and fecal colonization among burn patients. The study was designed over two phases. Phase I involved conventional cleaning monitoring by visual inspection, while phase II involved the ATP bioluminescence tool. In both phases, clinical and environmental swabs were collected for microbial culture and identification. Gram-negative bacteria were screened for carbapenem resistance. Among the five selected cases, MALDI-TOF and Vitek2 were utilized to test for phenotypic relatedness between common isolates from different clinical and environmental sources. The wound infection rate was significantly reduced from 23% in phase I to 8% in phase II (p-value <0.005). Fecal colonization by CR bacteria demonstrated 7% and 14% in phase I and phase II, respectively. Environmental culture demonstrated significantly decreased microbial isolation rates from 37% (phase I) to 10% (phase II) (p-value<0.001) with a non-significant decrease in CR bacteria. Total pass and failed cleaning rates for ATP bioluminescence were 70.9% and 6.08%, respectively. Common isolates in 3 cases exhibited a similarity of >65% by MALDI-TOF and the identical resistance phenotypes by Vitek2. The ATP bioluminescence cleaning verification system has been proven a rapid and objective tool that positively impacts microbial isolation rates from clinical and environmental samples.

Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). To assess the effect of COVID-19 disease on hematology, coagulation profiles, renal and liver function over the course of the disease, the following laboratory tests were performed: WBCs per mm3, lymphocytes count, Platelet, D-dimmer, AST, Albumin, LDH, Ferritin, CRP, blood culture and viral loads. Patients were grouped according to their initial viral load (Group1: low viral load (L), Group 2: moderate viral load (I), and Group 3, high viral load (H)). The study population median age of the patients was 58 years, and 69% were male. Generally, all patients were admitted to the intensive care unit. Most of the patients (79.5%) had an intermediate viral load, 14.5% had a high viral load, and 5.7% had a low viral load. The Kusakal-Walli’s test revealed a significant difference in the levels of white blood cells, lymphocytes, platelet, D-dimer, AST, CRP, and ferritin (p <0.0001). One hundred twenty-two isolates were recovered from 5362 blood cultures; where as 75% were multiple resistant to three classes of antibiotics and more. True bacteremia was most commonly caused by Klebsiella pneumoniae (45%), Acinetobacter baumannii (30%), and C. albicans (7%). The potential risk factors of advanced age, lymphopenia, D-dimer concentrations greater than 2µg/mL, and ferritin concentrations greater than 400ng/mL may assist clinicians to improve the management of the case and reduce mortality.

Published: July 2022

En la estabilidad de taludes, un factor importante a considerar es la presencia de grietas de tracción. Con los años, la estabilidad se ha analizado utilizando el método analítico de equilibrio límite y más recientemente con el uso de métodos numéricos. En investigaciones anteriores, la ubicación y/o la profundidad de la grieta, se fijaron previamente como un dato conocido. En esta investigación, utilizando el método de elementos finitos, el comportamiento de la superficie de rotura, se simuló con la presencia de grietas de tracción en suelos, considerando la influencia de las condiciones geométricas (inclinación del talud y altura), así; se determinaron entonces la ubicación y profundidad de la grieta de tracción. Finalmente, se concluye que se producen grietas de tracción en el caso de los suelos finos estudiados, a medida que la inclinación y la altura del talud aumentan, la distancia desde la base del talud a la grieta disminuye, la profundidad de la grieta aumenta y por consiguiente, el factor de seguridad disminuye, que resulta un factor determinante en la estabilidad del talud.

Mahalnya pupuk dan pestisida tidak hanya berdampak pada tingginya biaya produksi, tetapi efek jangka panjang terhadap tanah persawahan yang mengalami penurunan kualitas dikarenakan bahan-bahan kimia tidak dapat terdegradasi. Saat ini petani di desa Pojok masih sangat tergantung kepada pupuk kimia sebagai upaya peningkatan hasil produksi. Namun disisi lain residu pupuk pada komoditas pertanian terhadap lingkungan yang cukup tinggi, hal ini akan menurunkan kualitas tanah dan berdampak pada kualitas tanaman. Oleh karena itu perlu ada nya solusi untuk mengatasi hal tersebut yaitu salah satunya dengan Sistem Padi Organik (SPO). Kegiatan dengan metode SPO dilaksanakan dengan beberapa tahapan sebagai berikut: 1) sosialisasi pelaksanaan kegiatan, 2) penyuluhan pertanian organic, 3) pelatihan penerapan sistem padi organik di lahan persawahan. Hasil yang diperoleh yaitu petani dan perangkat desa sangat antusias dan tertarik dalam penerapan SPO, dibuktikan dengan adanya peran serta petani dalam proses kegiatan sosialisasi sampai panen. Dari hasil penerapan SPO diperoleh biaya produksi menjadi semakin rendah dan hasil jual gabah lebih tinggi dibandingkan dengan gabah dari metode penanaman dengan pupuk kimia.

“A So-Called Tenants’ Union”: Defining the Organizational Power of Tenants within and outside the Law
Authors: Shafei Seema
Published: July 2022

How is a tenants’ union defined within the parameters of the law? How have tenants been defining themselves as a union outside of the law? This paper will examine the answers to these questions by laying out the historical context of the current rental regime in Ontario, analyzing the current case law on tenant associational activity, and highlighting the organizational tactics that tenants’ associations have used to build power where the law has failed to protect their interests. While advancing a legal case for robust tenant associational rights may force landlords to the bargaining table, the future of tenants’ associations in and outside of the law should draw on lessons learned from the labour movement in Canada with a “whole-worker organizing” approach in mind.
