Excessive production of renal
reactive oxygen species (ROS) play a major role in diabetic kidney disease
(DKD). Here, we provide key novel findings demonstrating the predominant pathological role of the prooxidant
enzyme NADPH oxidase-NOX5 in DKD, independent of the previously
characterised NOX4 pathway.
In diabetic patients, we found increased expression of renal NOX5 in
association with enhanced ROS formation and upregulation of ROS-sensitive
factors EGR-1 (early
growth response 1), PKC-α (protein kinase C- α) and a key metabolic gene
involved in redox balance, TXNIP (thioredoxin-interacting
protein). In preclinical models
of DKD, overexpression of NOX5 in Nox4 deficient mice enhances kidney damage by increasing albuminuria and augmenting renal fibrosis
and inflammation via enhanced ROS formation and the modulation of EGR1, TXNIP,
ERK1/2, PKC-α and PKC-ε. In addition, the only first in class NOX inhibitor,
GKT137831 appears to be ineffective in the presence of NOX5 expression in
diabetes. In vitro, silencing of NOX5
in human mesangial cells attenuated high glucose induced upregulation of EGR1, PKC-α,
and TXNIP as well as markers of
inflammation (TLR4 and MCP-1) and fibrosis (CTGF and collagens I and III) via
reduction in ROS formation. Collectively, these findings identify NOX5
as a superior target in human DKD compared to other NOX isoforms such as NOX4 which may have been
overinterpreted in previous rodent studies.

There is accumulating evidence that mitochondrial dysfunction is
associated with the contribution of diabetes to Alzheimer's disease (AD)
progression. Neuronal mitochondrial proteins found in plasma
neuronal-derived exosomes(NDEs) at levels that reflect those in brain
neurons. Here, we tested the performance of mitochondrial proteins in
plasma NDEs to predict cognitive decline and brain injury in diabetic
participants. Plasma neuroexosomal proteins were measured by ELISA kits.
Diagnostic accuracy for progressive MCI and AD was obtained for
mitochondrial proteins using receiver operating curve (ROC) analyses.
The associations of mitochondrial proteins with the conversion from MCI
to AD were assessed by Cox proportional hazard regression analysis. We
found that plasma neuroexosomalNDUFS3 and SDHB levels were lower in
progressive MCI (274.4 ± 78.6 pg/ml, 1536.7 ± 342.8 pg/ml) than in
stable MCI (319.9 ± 109.8 pg/ml, P < 0.05; 1824.7 ± 606.4 pg/ml, P
< 0.05) subjects. Both plasma neuroexosomal NDUFS3 and SDHB offer
diagnostic utility for AD. Low plasma neuroexosomalSDHB levels
significantly predicted conversion from MCI to AD. In addition, low
mitochondrial proteins levels were associated with the rate of
hippocampal and gray matter atrophy, reduced AD signature cortical
thickness in progressive MCI over the follow-up period. These data
suggest that both plasma neuroexosomal NDUFS3 and SDHB are already
increased at the early clinical stage of AD, and indicate the promise of
plasma neuroexosomal mitochondrial proteins as diagnostic and
prognostic biomarkers for the earliest symptomatic stage of AD in
diabetic participants.

Fatty-acid (FA) signaling contributes to β-cell mass expansion in response to nutrient
excess, but the underlying mechanisms are poorly understood. In the presence of elevated
glucose, FA metabolism is shifted towards synthesis of complex lipids,
including sphingolipids. Here
we tested the hypothesis that sphingolipids are involved in the β-cell proliferative
response to FA. Isolated rat islets were exposed to FA and 16.7 mM glucose for
48-72 h and the contribution of the de novo sphingolipid synthesis
pathway was tested using the serine palmitoyltransferase inhibitor myriocin, the sphingosine kinase (SphK) inhibitor SKI II, or knockdown of SphK, fatty-acid-elongase-1 (ELOVL1)
and acyl-CoA-binding protein (ACBP). Rats were infused with glucose and the lipid
emulsion ClinOleic and received SKI II by gavage. B-cell proliferation was assessed by immunochemistry or flow cytometry. Sphingolipids were analyzed by LC-MS/MS.
Amongst the FA tested, only oleate increased β-cell proliferation. Myriocin, SKI II, and SphK knockdown all
decreased oleate-induced b-cell proliferation. Oleate exposure did not increase the total amount of sphingolipids
but led to a specific rise in 24:1 species. Knockdown of ACBP or ELOVL1 inhibited oleate-induced β-cell
proliferation. We conclude that unsaturated very long-chain sphingolipids
produced from the available C24:1 acyl-CoA pool mediate oleate-induced β-cell
proliferation in rats.

Published: March 2022

“...O exercício físico de baixa intensidade é considerado muito seguro e os seus efeitos benéficos são realçados em todas idades e em quase todas as situações. Por outro lado, o exercício físico intenso e o stress associado à competição são gatilhos que podem originar a PCS ou o enfarte do miocárdio... Duas outras importantes conclusões sobressaíram desta análise: a incidência de PCS permaneceu relativamente estável ao longo do tempo em que o estudo decorreu, enquanto a mortalidade diminuiu significativamente devido ao aumento na taxa de sobrevivência (3 vezes), consequência da melhoria das medidas de socorro e do uso muito mais frequente do desfibrilador automático externo (18 vezes mais)... Os autores salientam, a propósito das medidas de prevenção deste evento, as duas estratégias fundamentais: triagem sistemática dos praticantes através do exame médico-desportivo e das medidas de socorro e de reanimação (RCR) imediatas no terreno...”

Study on fungal life activities of decomposing wood fibers
Authors: Zhang Ran , Zhou Lan , Zhang Jiaming
Published: March 2022

The decomposition of plant material and woody fibers is a key component in the carbon cycle. In the whole process, fungi are the key factor to decompose wood fiber. A recent research indicates that there is a certain relationship between fungi traits that determine the decomposition rate. Based on the results of the research, our team construct a mathematical model to simulate the decomposition of ground litter and woody fibers in the presence of a variety of fungi and explore the decomposition under the condition of interaction, different environment, change of environment and biodiversity.In this paper, we start by analyzing the experimental data in the reference of the MCM problem A and we use the cluster analysis method to divide the fungi in the data into two groups according to the growth rate, competitiveness and environmental tolerance. Then on the basis of topic requirements, we construct our decomposition model that the decomposition rate of fungi per millimeter is only related to the growth rate of fungi population and the moisture tolerance of fungi and this relationship is linear. We use our decomposition model to add up the decomposition effects of the two types of fungi. Our conclusion is that the decomposition rate of fungal community was the sum of the decomposition rates of each fungal population.

Published: March 2022

Background: An aspect that becomes relevant in the current pandemic situation is the probable psychological effects that it may cause. A series of studies have shown that these kinds of critical situations have effects such as the development of anxiety processes in people. Hence the interest in knowing how health habits help to adapt to the pandemic and mediate anxiety processes. Objective: to analyze the relationship of healthy habits with anxiety and adaptation to confinement. Method: 7,439 people from Mexico participated, with ages between 18 and 80 years (M = 36.99, SD = 14.00). Results: We found that sleep (58%), eating (29%) and physical activity (52%) habits have been affected by confinement; 11.5% of the participants showed indicators of anxiety. The 9% of participants adapted poorly to confinement. The variable that best predicts adaptation to confinement is anxiety, followed by food, sleep, and physical activity. Those who are most affected by habits are young people and women by gender. Conclusions: The pandemic has led to changes in negative habits in a large sector of the population, which are now considered risk factors for physical and mental health. In addition, habits are associated with anxiety and adaptation, so it is necessary to provide society with strategies that allow proper management of habits, which can prevent the manifestation of anxiety.

Authors: Musdi Edwin
Published: March 2022

Technological development is very possible to use in learning activities for improving the quality of education. Much research has strongly advocated the use and integration of technology in the learning process. One form of utilization of these technologies is the use of E-Modules. E-modules in learning are teaching materials used in assisting learning activities in the form of soft-files that are operated through computers. Interactive e-learning module motivates students to learn more spiritually, actively and independently that can be used by teachers in the learning process. E-Modules allow students to learn not only in the classroom but wherever they are. However, there are many teachers who cannot create or design e-modules. In West Sumatra itself, especially the city of Padang Panjang, e-modules are unknown by teachers. Based on the results of interviews with math subject teachers who are also chairmen of the High School Mathematics MGMP in Padang Panjang City, in general the teachers in the city of Padang Panjang do not know about e-modules and really need training or guidance on e-modules themselves to improve quality their learning in class. Based on this, it was felt necessary to implement an activity program to improve the ability of mathematics teachers in desaining E-Modules in the Padang Panjang city with the partners of Mathematics MGMP. This activity will be facilitated by the IT team who will explain the ins and outs of the E-Module so that technical knowledge about e-modules can be properly controlled by partners. In addition to the IT team this program also involves a team of Mathematics experts who will evaluate the modules designed by teachers during the implementation of the activities so that the quality of modules that can be used by students can be maintained. The mechanism for implementing PKM activities is carried out using action research steps which consist of 4 (four) stages, namely: planning, action, observation and evaluation, and reflection. The implementation of this activity creates e-learning modules that can be designed by subject teachers, especially mathematics.

Published: March 2022

Introduction

Household food insecurity (HFI) is a persistent public health issue in Canada that may have disproportionately affected certain subgroups of the population during the COVID-19 pandemic. The purpose of this systematic review is to report on the prevalence of HFI in the Canadian general population and in subpopulations after the declaration of the COVID-19 pandemic in March 2020.

Methods

Sixteen databases were searched from 1 March 2020 to 5 May 2021. Abstract and full-text screening was conducted by one reviewer and the inclusions verified by a second reviewer. Only studies that reported on the prevalence of HFI in Canadian households were included. Data extraction, risk of bias and certainty of the evidence assessments were conducted by two reviewers.

Results

Of 8986 studies identified in the search, four studies, three of which collected data in April and May 2020, were included. The evidence concerning the prevalence of HFI during the COVID-19 pandemic is very uncertain. The prevalence of HFI (marginal to severe) ranged from 14% to 17% in the general population. Working-age populations aged 18 to 44 years had higher HFI (range: 18%–23%) than adults aged 60+ years (5%–11%). Some of the highest HFI prevalence was observed among households with children (range: 19%–22%), those who had lost their jobs or stopped working due to COVID-19 (24%–39%) and those with job insecurity (26%).

Conclusion

The evidence suggests that the COVID-19 pandemic may have slightly increased total household food insecurity in Canada during the COVID-19 pandemic, especially in populations that were already vulnerable to HFI. There is a need to continue to monitor HFI in Canada.

Introduction

L’insécurité alimentaire des ménages (IAM), un problème de santé publique chronique au Canada, pourrait avoir touché de façon disproportionnée certains groupes de population durant la pandémie de COVID 19. Cette revue systématique vise à analyser la prévalence de l’IAM au sein de la population canadienne générale ainsi qu’au sein de certains groupes depuis le début officiel de la pandémie de COVID 19 en mars 2020.

Méthodologie

Seize bases de données ont été consultées pour la période allant du 1er mars 2020 au 5 mai 2021. Un premier chercheur a réalisé une analyse systématique des résumés et des textes intégraux et un second chercheur a vérifié les études retenues. Seules les études portant sur la prévalence de l’insécurité alimentaire des ménages canadiens ont été retenues. Deux chercheurs ont procédé à l’extraction des données ainsi qu’à l’évaluation du risque de biais et du degré de certitude des données probantes.

Résultats

Parmi les 8 986 études sélectionnées, quatre ont été finalement retenues, dont trois s’appuyant sur des données collectées en avril-mai 2020. Les données probantes sur la prévalence de l’insécurité alimentaire durant la pandémie de COVID 19 sont peu concluantes. La prévalence de l’IAM (marginale à grave) au sein de la population générale varie entre 14 % et 17 %. Elle est plus élevée chez les personnes en âge de travailler de 18 à 44 ans (18 % à 23 %) que chez les adultes de 60 ans et plus (5 % à 11 %). Certaines des prévalences les plus élevées d’insécurité alimentaire ont été observées au sein des ménages avec enfants (19 % à 22 %), des ménages dont un membre a perdu son emploi ou cessé de travailler en raison de la COVID 19 (24 % à 39 %) et des ménages confrontés à la précarité d’emploi (26 %).

Conclusion

D’après les données probantes, la pandémie de COVID 19 pourrait avoir contribué à une légère augmentation de l’insécurité alimentaire globale des ménages canadiens, particulièrement celle des ménages déjà les plus touchés. Il faut continuer à maintenir la surveillance en matière d’insécurité alimentaire au sein des ménages canadiens.

Introduction

Étant donné la diffusion rapide de l’information en ligne sur la santé liée au coronavirus, il est important de s’assurer que cette information est fiable et communiquée efficacement. Cette étude traite de la diffusion de l’information relevant de la littératie en matière de santé par les établissements postsecondaires canadiens à l’intention des étudiants universitaires par rapport aux directives provinciales et fédérales sur la COVID 19.

Méthodologie

Nous avons effectué une analyse systématique des pages Web des gouvernements fédéral et provinciaux du Canada et de diverses universités canadiennes pour déterminer comment l’information en matière de santé est présentée aux étudiants universitaires. Nous avons utilisé notre enquête sur la littératie en matière de santé menée précédemment auprès d’étudiants postsecondaires du Canada comme cadre d’échantillonnage pour sélectionner les établissements d’enseignement à inclure. Nous avons ensuite utilisé des termes de recherche spécifiques pour obtenir les pages Web pertinentes, à l’aide de Google et des fonctions de recherche intégrées aux sites Web des divers gouvernements, puis nous avons comparé l’information disponible sur les mesures de lutte contre la pandémie en fonction des procédures d’intervention, des sources d’expertise et des approches liées à l’image de marque des diverses universités.

Résultats

Notre analyse des pages Web des gouvernements et de celles des universités au Canada révèle que les universités ont créé de manière similaire une page principale pour les mises à jour et l’information sur la COVID 19 et qu’elles ont renvoyé aux organismes du secteur public comme ressource principale, mais qu’elles ont obtenu différemment leur information à partir des sources provinciales et locales consultées. Elles ont également agi différement dans leurs stratégies de communication et de présentation de cette information à leurs populations étudiantes respectives.

Conclusion

Les universités de notre échantillon ont défini des politiques similaires pour leurs étudiants, congruentes avec les recommandations du gouvernement canadien en matière de santé publique et leurs autorités sanitaires provinciales ou régionales respectives. Il est important de maintenir l’exactitude de ces sources d’information afin d’assurer la littératie en matière de santé des étudiants et de contrer la désinformation sur la COVID 19.
Reading Nagamese ‘MakroLi ’as a Pastoral Lyric
Authors: Sharma Dr Shreeja Tripathi
Published: March 2022

This research paper seeks to studyMakro Li,  the indigenous group song of the Chakhesang tribe of Nagamese people with reference to the conventions of pastoral poetry.The song offers a glimpse into idyllic village life in the hilly countryside and invokes the utopian vision of purity and innocence in tranquil pastoral life. The lyrics are also interspersed with nuances of post-pastoral eco-poetics.The folk song thus echoes elements of  pastoraland post-pastoral poetry and offers a glimpse of Nagamese culture through the description of workers in their paddy fields.
The White Tiger : A Critique

This work is a comprehensive study which brings out the narrative techniques used by Arvind Adiga who has a fascination for his past as a boy belonging to Chennai and feels a bond with the life of middle class people. His view of looking at history in an alternative way reflects in this work. He looks at violence as a channel for freedom and this view is realized in the form of the protagonist, Balram Halwai murdering his master Mr. Ashok. The novel is also a way of looking at India in its flux of economic changes as against China, the country of communism. Apart from sharing the view of the author, the work brings out the aspects of light and dark, casteism, rural and urban life, difference between Indian and American culture, Indian politics and corruption. It is also peppered with humour here and there. Every detail has been incorporated in narrating the transformation of a poor village boy into a successful entrepreneur.

Most promising materials for creating biointerfaces are electrically conductive materials based on carbon and its modifications. Such materials can be used for targeted stimulation of cells and tissues with high spatial resolution. In this work, carbon nanotubes are considered to be used for electrically conductive materials creation because of their outstanding electrical, mechanical and optical properties. It was shown that under the influence of laser radiation, it is possible to achieve the effect of welding with the formation of branched networks on a silicon substrate and within the biopolymer matrix. As a result of experimental studies, the radiation energy density was established at which the effect of single-walled carbon nanotubes bonding to each other appears – 0.061 J/cm2. The mechanism of porous materials based on biopolymers albumin, collagen and chitosan formation containing single-walled carbon nanotubes has been determined. Materials were made from single-walled carbon nanotubes and biopolymers with controlled pore size. The pore volume was more than 60 % of the nanocomposite volume.

Syntactic materials (spheroplastics) having low density due to structural features, depending on the material of the microsphere walls can have a sufficiently high strength and low thermal conductivity, which makes them promising for use as heat insulation materials. By selecting the material of the microsphere walls and the concentration of the components of the spheroplastics, their dielectric characteristics can be significantly changed. In this work, the task of modeling the effective dielectric characteristics of a syntactic material with a polymer binder and filler in the form of hollow glass microspheres is considered, taking into account the presence of technological impurities in the material. A model for calculating the effective permittivity of a sample of a syntactic material was proposed, based on a model of a matrix composite with several types of inhomogeneous or homogeneous inclusions. To calculate, a generalized effective-field approximation for a heterogeneous medium with coated inclusions was used. Model calculations were carried out for syntactic foam with an organosilicon binder polydime-thylsiloxane and hollow microspheres with E-glass shell with some moisture presence in the material. Frequency dielectric characteristics of this material were obtained in the range of 102–1010 Hz. It has been shown that an increase in the volume fraction of hollow microspheres leads to a decrease in the dielectric constant and the tangent of the dielectric loss angle. It has also been shown that the calculated values are in satisfactory accordance with the experimental data obtained at an electromagnetic field frequency of 9.8 GHz.

Objective: To evaluate feasibility of hand gloves as a rubber dam isolation alternative, in respect of physical properties. Materials and Methods: A randomized controlled trial study design was used. Three types of gloves were tested with two types of a rubber dam used as the control group. Cut-out pattern of dumb-bell shapes were made from 35 samples for each type of groups and tensile strength were tested using Universal Testing Machine and the Trapezium X software. All tests for physical requirements were performed in accordance with American Society for Testing and Materials D412, Standard Test Methods for Vulcanized Rubber and Thermoplastic Rubbers and Thermoplastic Elastomers-Tension. Findings were analyzed by analysis of variance (ANOVA) and differences were compared using a Tukey-Kramer interval calculated at the 0.05 significance level. Results: Heavy gauge rubber dam has the highest Mean (calculated at the 0.05 significance level) except for maximum stress calculated at entire area. Medium-gauge rubber dam has significantly higher tensile strength (44.5075 N/mm2) when compared to heavy-gauge rubber dam (35.7787 N/mm2) although it was 0.09mm thinner. Discovery 2020 Powder Free Latex Examination Gloves with tensile strength value of 28.5922 N/mm2 (±3.27366) is more than the minimum requirement specified by American Federal Specification ZZ-R90B Rubber Dam (Dental, 1985) (4000 pounds per square inch or 27.6 N/mm2). For all variable tested, all groups are significantly different from each other. The mean square between the groups was quite large. Conclusion: This study shows that there are significant differences between the physical strength of latex gloves when compared to rubber dam. However, the comparison between thickness and tensile strength among various rubber dam, did not correspond proportionately. Only one type of rubber gloves met the minimum requirement but that is just one aspect. In view of these mixed results, more research is needed before we can conclude that it is feasable that we use hand gloves to replace rubber dam.
