Stroke and migraine are leading neurological conditions on a global scale
Authors: Pathan Aslam
Published: August 2023

Neurological disorders are now being more widely recognized as significant contributors to mortality and disability on a global scale. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 provided the most comprehensive and up-to-date estimates of the global, regional, and national burden from neurological disorders. According to the findings of the study, the two largest contributors of neurological DALYs (disability-adjusted life-years) were stroke (42·2% [38·6–46·1]), migraine (16·3% [11·7–20·8]). Stroke ranked first globally among neurological disorders in terms of age-standardised DALY rates in 19 of 21 world regions except in Australasia and Western Europe. Migraine ranked first in Australasia and Western Europe. Stroke burden rapidly increased up to the age of about 80 years, and was the dominant cause of neurological burden between ages 60 and 84 years, more so in males than females. Migraine and tension-type headaches were large contributors in young and middle-aged adults, with much higher numbers in females than males

O comportamento animal é um dos fatores que caracterizam uma espécie, mantê-lo mais próximo ao natural em ambiente cativo é fundamental ao bem-estar. O Enriquecimento Ambiental tem o objetivo de estimular os comportamentos naturais das espécies, evitando a previsibilidade. Deste modo, este trabalho visa avaliar alterações comportamentais pela aplicação de atividades de Enriquecimento Ambiental (EA) com Jabutis-piranga (Chelonoidis carbonaria), mantidos no Bioparque Zoobotânico da cidade de Teresina, Piauí. O estudo incluiu a participação de 20 espécimes (machos e fêmeas) com a elaboração de planilhas para Observação em Campo e Etograma, através dos métodos de Amostragem em livre ocorrência (Ad libitum) e Animal Focal em registro contínuo, totalizando 40h de observação. Os registros foram feitos sem Enriquecimento Ambiental (20h de observação), e com as atividades propostas, analisando o comportamento por tempo de interação com o EA (20h de observação). As categorias comportamentais foram divididas em: inatividade, locomoção, exploração, atividades fisiológicas e interação social. Os dados obtidos foram contabilizados para cada categoria do Etograma. Foram contabilizados em 20 horas sem Enriquecimento Ambiental: 61% de inatividade; 35% de locomoção; 2% de exploração; 1% de atividades fisiológicas e 1% de interação social. Em contrapartida, com a aplicação do EA, obteve-se: 38% de inatividade; 21% de locomoção; 9% de exploração; 30% de atividades fisiológicas e 2% de interação. Observou-se a variação de comportamentos, como: redução no tempo de inatividade, aumento do tempo de exploração, atividades fisiológicas e interação social. Com isso, notou-se que a aplicação de enriquecimento ambiental é de grande importância, visto que se trata de uma ferramenta essencial para o bem-estar e qualidade de vida em cativeiro, pois proporciona uma maior variedade de comportamentos dos animais semelhantes à vida livre.

Japan Biodiversity Information Initiative (JBIF)'s Efforts to Collect and Publish Biodiversity Information from Japan
Authors: Kakizoe Showtaro , Ota Aino , Hosoya Tsuyoshi , Jinbo Utsugi
Published: August 2023

The Japan Biodiversity Information Initiative (JBIF) was originally established in 2007 as the Global Biodiversity Information Facility (GBIF) Japan National Node to aggregate biodiversity data in Japan and conduct publications through GBIF. JBIF was later renamed after Japan became a GBIF observer, but activities including data publication through GBIF have continued to the present. JBIF operates with the support of the National BioResource Project (NBRP) by the Ministry of Education, Culture, Sports, Science and Technology (MEXT), with collaboration from three institutions: the National Institute of Genetics (NIG), the National Institute for Environmental Studies (NIES), and the National Museum of Nature and Science (NMNS). The NBRP is a project that focuses on the collection, preservation, provision, and enhancement of bioresources.

JBIF collects both observation and specimen data and publishes them through GBIF. For domestic data use, a search system for data published by JBIF is available on the JBIF website. Moreover, NMNS managed a museum network called the Science Museum Net (S-Net), and bilingual (Japanese and English) specimen data collected by S-Net is also available via the S-Net portal site. We are working to promote the biodiversity informatics field in Japan through a translation of the GBIF resources, including the website, important documents such as the GBIF Science Review, as well as organize workshops and conferences, primarily targeting students, researchers, museum curators, and local government officials, to facilitate the sharing of information and exchange of opinions on biodiversity information.

To date, Japan has published 564 datasets and over 12 million occurrences to GBIF, making it the third-largest contributor of data to GBIF in Asia, following India and Taiwan. Moreover, regarding specimen-based occurrence data, Japan is the largest contributor in Asia.

In this presentation, we will introduce JBIF's initiatives and future activities.
Leadership in the New Normal
Authors: Harriott Suzzette Ann-Marie
Published: August 2023

This chapter presents a secondary analysis of five case studies to explore leadership dynamics in the context of the “new normal.” This analysis illuminates the essential role of transformational leadership in addressing emergent challenges. The chapter focuses on four primary facets: emotional intelligence; conflict management; diversity, equity, and inclusion; and fostering an environment of learning and development. Results reveal that successful leaders can navigate conflict effectively and encourage emotional intelligence; enhance diversity, equity, and inclusion; and promote an ecosystem for learning and development within their teams. Further, findings demonstrate that cultivating transformational leadership styles can significantly enhance these competencies. As such, transformational leadership emerges as a crucial strategy for organizations aiming to succeed in the new normal. The chapter concludes with recommendations for leaders and organizations based on the insights gleaned from the case studies.

Published: August 2023

This study aimed to analyze the demand profile and the challenges of regulating access to specialized care, considering the referenced cases and the perspectives of physicians in the Family Health Strategy (FHS). This was a mixed methods study, with a quantitative and qualitative approach, carried out in an inland municipality of the state of Ceará, Brazil. Quantitative data were obtained from Primary Health Care (PHC) referral forms, registered with the regulation center. Focus groups were held, involving 13 FHS physicians. The results showed 643 referrals, the majority (74.2%) corresponded to the request for tests, and 61.6% did not have a diagnostic hypothesis, which corroborates the increase in waiting time. Spine tomography was the exam with the highest amount in relation to the shortest waiting time. Regarding consultation, otorhinolaryngology was the specialty with the highest demand (17.7%). Physicians reported weaknesses and challenges in regulation, such as communication failures and the lack of counter-referral flows, which compromise Primary Health Care coordination, continuity and resolvability. The need to reorganize and qualify the regulatory processes in the municipality is pointed out.

Published: August 2023

Methylene blue, a synthetic organic dye commonly used in industries, poses health and environmental concerns. In the current study, activated carbon derived from wheat straw was used as an adsorbent for removing methylene blue dye from water. The effects of various operating parameters, such as pH, contact time, temperature, mass of adsorbent, and initial concentration of the pollutant, were investigated to understand the adsorption mechanism. The results showed that the activated carbon prepared from wheat straw through a chemical activation with H3PO4 was highly effective in adsorbing methylene blue. The Langmuir isotherm provided the best fit to the experimental data, indicating favorable adsorption with a maximum adsorption capacity of 5.2548 mg/g. The kinetic study revealed that the adsorption process followed a pseudo second-order model with significant intraparticle diffusion. The process was found to be spontaneous and endothermic. The activated carbon derived from wheat straw exhibited comparable or even greater adsorption capacity compared to other agricultural by-products and commercial activated carbons. Overall, these findings suggest that wheat straw-derived activated carbon has promising potential as a low-cost adsorbent for removing methylene blue and other organic pollutants from water

Moroccan industry, like most industries around the world, today faces a water scarcity. Water is one of the basic utilities for all kinds of production, especially in the agro-food sector. Morocco, a country of bioclimatic and ecological transition with fragile resources, is threatened with rapid degradation in the event of overexploitation of underground water reserves. Indeed, the evolution of the water supply over the last decade already testifies to the irregularity of the outlook and confirms climate failure. “From 1990 to 2000, the resources in m3 per inhabitant per year fell from 1200 to 950. In 2020 the water resources are only around 600m3 / inhabitant / year, at a time when the demand for water total has reached the ceiling of 20 to 21km3 of water that can be mobilized. The country will drop to the shortage threshold for 500m3 / inhabitant / year around the year 2030".In fact, Morocco has launched programs to save water and review some resource allocations in order to meet growing needs. One of these programs is the launch of 10-95 law. It about the regulation of water discharges by establishing a financing instrument based on “the polluter pays” principle. This law has forced several industries, to install wastewater treatment plants (WWTP) for their water discharges to the extent that they meet the standards defined by Law 10-95. On this work, we will present an analysis of the operation of a wastewater treatment plant in a Moroccan dairy, the issues that have arisen and the solutions that have been provided. The analysis of the influential of the WWTP during the different phases of treatment gave results, which allowed us to optimize the performance of each phase and reduce the cost of running the WWTP.
The Possibility of Using 1301 and 2402 Mixtures of Halons for Fire Extinguishing Purposes
Authors: Likhnyovskyi Ruslan , Tsapko Yuriy , Kovalenko Vitalii , Onyshchuk Andrii
Published: August 2023

Halons are usually used for fire extinguishing where other types of extinguishing agents cannot be used. Their use does not require disconnection of electrical networks, does not lead to any damage, and after airing the premises, these substances do not leave any residues. Halons are used as flame retardants in concentrations (from 2 to 12% vol.). In the case of their use, a decrease in the oxygen content in the air of the flame center’s due to dilution is not significant, and extinguishing occurs as a result of the slowing down and interruption of chain chemical reactions in the flame. Combustion inhibitors play the role of a "negative catalyst", the mechanism of their action consists in high reactivity to interact with radicals with the formation of inert compounds, thereby interrupting the chain reaction of combustion and slowing down its development. The concentrations of bromotrifluoromethane (halon 1301) and 1,2-dibromotetrafluoroethane (halon 2402) in the mixtures were determined by the gas chromatographic method, and experimental researches for determining the minimum fire-extinguishing concentration established that the halons 1301 and 2402 mixtures show high efficiency in extinguishing flames. Established, that the mixture of halons 1301 and 2402 with the concentration of the latter in the range of 60÷65% exhibits the best minimum fire-extinguishing concentration. At these values, the minimum fire-extinguishing concentration did not exceed 2.0% vol. It was determined that when reducing the concentration of oxygen in the air by halon 1301 from 20.5 to 19% of volume, the concentration of halon 2402 for extinguishing n-heptane decreases by 2.5 times. Inhibition of the n-heptane flame combustion process by such mixtures of halons is associated with the decomposition of halons under the influence of temperature with the absorption of heat and releasing of combustion inhibitors, a change in the direction of decomposition towards the formation of non-combustible gases and the cessation of oxygen access. This indicates possibility of using available gas extinguishing substances - halons - for fire extinguishing.

This article discusses the use of solar dryers as a method for stabilizing and reducing the volume of residual sludge produced by wastewater treatment facilities. The study focused on the convective drying behavior of sewage sludge produced by the wastewater treatment plant of Meknes City under convective solar drying. The study aimed to investigate the drying kinetics of sewage sludge and emphasize the effect of temperature and water content on the evolution of the drying rate. The measured water content values showed a decrease as drying time increased. The results revealed the presence of phase II, which characterizes the decreasing rate drying period, and the absence of phase I, which describes the constant rate drying period.The study developed an empirical model to describe the kinetic behavior of convective solar drying of Moroccan domestic sludge. The model can be used to predict the shape of a drying curve under other aerothermal conditions. Additionally, the study analyzed the thermal diffusivity and activation energy of sewage sludge using an experimental macroscopic method based on Fick's diffusion model and the Arrhenius equation. The measured diffusion coefficient values range from 0,71 10-9 m2.s-1 to 1,47 10-9 m2.s-1, and the value of activation energy was evaluated at 17.54 kJ/mol.
Substantiation of the Swellable Coating Effectiveness for Fire Protection of Wooden Constructions

Published: August 2023

As a result of the studies of wood flame retardant effect on ignition, the parameters of flame propagation and combustion suppression were established, which makes it possible to influence this process. It has been proven that the creation of a protective layer on the surface of wood prevents it from heating up to a critical temperature. At this moment, a certain amount of combustible gases is released, that is, intense decomposition and ignition occurs. This knowledge makes it possible to establish the dependence of the process of inhibiting the burning rate of wood on the quality of fire protection and the properties of the applied protective mixtures. By experimentally examining wood samples, it was established that the sample without treating caught fire on 52 s and in 100 seconds the flame spread over the entire surface, the sample fire-retardant "FIREWALL-ATTIK" did not catch fire, impregnating solution ВС-13 and "FIREWALL-SV-1", namely a mixture of 271.1 g/m2, took 570 and 560 s, the flame spread to the surface only in areas closer to the source, the highest flue gas temperature of 86 and was reached more than 5 times faster, and the flammability index decreased to 4. For the sample protected by "FIREWALL-LAC" ignition occurred in the last second, the flame was recorded at level 0. For the sample fire-protected by "FIREWALL-WOOD" coating no ignition occurred, combustibility index is 0. Due to this, it became possible to determine the conditions for changing the combustion barrier to heat conductivity. Correspondence between the obtained experimental results of the wood burning rate and the analytically calculated equations was found.Taking into account the above, there is a basis for asserting the possibility of purposeful management of the processes of protecting wood from fire by applying fire-retardant mixtures, which under certain conditions are able to create a protective layer on the surface of the material, which restrains the growth of the rate of wood burning.
Improvement Efficiency of Solar Cells Using III-V Dual Junction: InGap/GaAs
Authors: Sabri Sara , Malek Rachid , Kassmi Khalil
Published: August 2023

Renewable energy is a very minor percentage of energy consumed in the world. Fossil fuels still dominate despite their drawbacks (degradation of the environment). Renewable energy is not yet cost competitive with fossil fuels. The conversion of energy from renewable sources, especially for inexhaustible and clean energy sources (solar cells), must be efficient to be viable for large scale use. Single junction cells (SJC) have a theoretical efficiency limit of 33.7%, called Shockley-Queisser limit (SQ). Because the cost of electricity produced from solar cells depends on their efficiency, improving their conversion efficiency is a key way to make them cost-competitive. The two most important efficiency losses in SJC are the inability to convert photons with energies below the band gap energy (Eg) into electricity and the thermalization of photon energies exceeding Eg. Dual Junction Solar Cells (DJSC) was proposed to avoid the efficiency losses and to overcome the SQ limit. Our simulation model, presented in a previous work, was used to calculate solar cells efficiency and to plot the current-voltage (I-V) characteristics and the power-voltage (P-V) characteristics curves. Our simulation results show that high conversion efficiencies can be achieved by DJSC, more than 43.5%.
Performative Resilience: Artistic Activism in Urban Spaces of Athens
Authors: Sakellariou Angeliki
Published: August 2023

Multiple constraints and passivity in urban space on a global scale, combined with the transformation of economic crises into spatial crises, have often led to a rise in civic participation as a form of radical response to contested social frameworks. In a number of cases, as these frameworks faced collapse, citizens have been led to bottom-up solutions which test their capacity to shape socio-spatial programs and disrupt the formality of space freeing it from constraints. Resilient cities – defined as cities that have the ability to absorb, recover and prepare for future shocks – are often at the epicenter of such multi-layered transformations. This paper explores some of the practices deployed by cultural practitioners (performers, visual artists, activists, architects etc.) in Athens, Greece as a response to conditions of austerity and political turmoil, as well as methods which could be deployed towards the re-appropriation of public space within oppressive socioeconomic and political contexts through empirical research. For the purpose of this analysis, ‘performance’ refers to a number of temporal kinesthetic actions of resilience that attempt to critique and interrogate sociopolitical narratives in public space. Through daily performative actions, groups of citizens attempt to rethink public space in order to confront newly urgent social needs and normalised behaviors. Cultural practitioners and urban activists, initiate performative actions as an attempt to demonstrate their resilience and capacity to adapt to austerity and crisis, pushing the boundaries of what public space can accommodate, examining complex social transformations in spatial terms.
Pharmacological inhibition of ictal and interictal epileptiform discharges
Authors: Sardo Stefano , Piras Barbara
Published: August 2023

Background: Epilepsy is a brain disorder characterized by an enduring predisposition to generate epileptic seizures. Seizures are a transient occurrence of signs and/or symptoms due to abnormal excessive and synchronous neuronal activity in the brain. Electroencephalogram (EEG), a non-invasive instrumental test, has an important role in the diagnosis of epilepsy, as well as in monitoring the results and long-term treatment because it can detect interictal and ictal discharges that are crucial for confirmation and classification of seizures. Antiepileptic drugs are the first treatment option in patients with epilepsy, although the effectiveness of such drugs is limited only to symptom control and requires a regular intaking by the patient. These drugs exploit the cell membrane channels, modifying their permeability, allowing either an increase in the inhibitory neurotransmission or the reduction in the excitatory one, by hyperpolarizing neurons and avoiding the recurrence of the epileptic seizures without reversing or stopping the underlying mechanism of epileptogenesis. Materials and Methods: The internship took place in the Neurophysiopathology department of the Antonio, Biagio and Cesare Arrigo’s hospital in Alessandria, from October 2022 to March 2023. During this period, it was possible to attend the emergency treatment of prolonged and recurrent epileptic seizures during EEGrafic recording and the consequential amendments of the ictal discharges induced by the administration of antiepileptic drugs. Follow up EEG was also performed to investigate the modifications of interictal activity after a period of treatment with antiepileptic drugs. The patient who has been analyzed in this paper, underwent EEG recordings obtained by using bridge electrodes placed on the scalp according to the international 10-20 system. Objectives: The aim of this study is to analyze the mechanisms of action of the main antiepileptic drugs, in relation to the physiological cellular mechanisms regulating the neuronal excitability and their effect on the ictal and interictal epileptiform discharges in the EEG recordings.

impact of fiscal policy on economic growth in Algeria: empirical study using SVAR model
Authors: Daoudi Mohammed
Published: August 2023

This study aims to analyze the impact of fiscal policy on economic growth in Algeria using the Autoregressive Structural Vector Methodology (SVAR), we will follow the method of working of Blanchard and Perotti (2002).We include only three variables: public spending G, Taxes (Direct taxes + Indirect taxes) TAX and GDP. The study concluded that there is a positive effect of public spending on the economic growth in Algeria, but it is smaller, and it is only in the short term and then turns into a negative impact in the medium and long term. This indicates that ordinary taxation is very limited to increase economic growth in Algeria with the strong presence of petroleum taxation. When a negative shock occurs in the price of a barrel then the effect is transferred directly to the public revenues and automatically to the public spending.

Published: August 2023

L’intégration des marchés des intrants agricoles est l’une des facettes de la mondialisation des systèmes alimentaires, en forte accélération ces dernières décennies. Elle permet à certaines filières agricoles nationales, ou certains de leurs segments, d’intégrer un système d’innovation agricole mondialisé, piloté par les multinationales. Les mécanismes de cette intégration, ses acteurs et ses conséquences sur le développement agricole dans les pays du Sud sont au centre des recherches sur les systèmes d’innovation agricole (SIA). Cet article analyse les rôles des fournisseurs d’intrants agricoles, particulièrement les vendeurs détaillants, dans l’introduction et la diffusion des innovations techniques dans la filière des cultures maraîchères sous serres froides à Biskra, wilaya leader de la filière. Basée sur l’approche des « fonctions des systèmes d'innovation », l’analyse met en évidence le double rôle des détaillants d’intrants dans le SIA : la création et la diffusion de connaissances (conseil agricole) et la mobilisation de ressources (crédit fournisseur).

Les épidémies de diarrhées aigües sporadiques restent préoccupantes dans des milieux vulnérables comme un orphelinat. L'objectif du  présent travail était de déterminer l’agent causal de l’épidémie de diarrhée aigüe sanglante qui s’est déclarée chez 143 enfants de 6 mois  à 15 ans d’un orphelinat de la ville de N’zérékoré. Selon une liste établie par le responsable de l’orphelinat, une analyse  systématique et biologique des selles par la Réaction en Chaine par polymérase a été effectuée pour détecter l’ADN des germes  communément impliqués dans des toxi-infections alimentaires. Les données ont été traitées avec le logiciel Bio statGV en ligne. Les résultats ont révélé 27% de positivité en ADN d’Escherichia coli O157-H7 dont 16,78% positifs chez les garçons contre 10,5% positifs chez  les filles. A part la tranche d’âge de 6 mois à 4 ans, présentant 6% de positivité, toutes les 3 autres tranches d’âge se valent, chacune à 7%  de positivité. Dix-sept (17%) de positivité en ADN de Campylobacter spp ont été détectées, dont 5,6% positifs chez les garçons contre  11,2% chez les filles. Aussi, 6,2% de co-infection E. coli O157 :H7 et Campylobacter ssp ont été détectées. E. coli O157 :H7, et les    Campylobacter spp étaient donc les responsables de l’épidémie à l’orphelinat.

The objective of this work was  to determine the causative agent of the bloody acute diarrhea epidemic which broke out in 143 children aged 6 months to 15 years from  an orphanage in the city of N'zérékoré. According to a list drawn up by the head of the orphanage, a systematic and biological analysis of  the stools by the Polymerase Chain Reaction was carried out to detect germs commonly involved in food poisoning. Data were processed  with the online Bio statGV software. The results revealed 27% positivity in Escherichia coli O157-H7 DNA, including 16.78% positive in boys  against 10.5% positive in girls. Apart from the age group from 6 months to 4 years, with 6% positivity, all the other 3 age groups are  equal, each at 7% positivity. Seventeen (17%) DNA positivity of Campylobacter spp was detected, including 5.6% positive in boys against  11.2% in girls. Also, 6.2% of E. coli O157:H7 and Campylobacter ssp co-infection were detected. E. coli O157:H7 and Campylobacter spp  were therefore responsible for the epidemic at the orphanage.

Au sahel, la production laitière varie selon la disponibilité des pâturages et cela nécessite des mesures d’adaptation. La présente étude  conduite dans la zone sahélienne du Burkina Faso a eu pour objectif d’évaluer l’effet de la supplémentation des vaches de race zébu  peulh en saison sèche avec du fourrage de cultures de variétés améliorées à double objectif sur leur production laitière. Pour ce faire,  vingt vaches ont été réparties en quatre traitements pour recevoir en plus du pâturage, une complémentation composée de 1,5 kg  tourteaux de coton et de 2 kg de fourrage qui étaient soit des fanes de niébé de variété améliorée (lot FNA), des fanes de niébé de variété  locale (lot FNL), de la paille de sorgho de variété améliorée (lot PSA) ou de la paille de sorgho de variété locale (lot PSL). Un lot de  cinq vaches, alimentées selon les pratiques paysannes, a servi de témoin. La production moyenne de lait trait par vache a été de 1,63 kg/j  pour le lot FNA, 1,21 kg/j pour celle du lot FNL, 1,02 kg/j pour celle du lot PSA et 0,95 kg/j pour celle du lot PSL. La production moyenne de  lait trait du lot FNA a été supérieure à celle du lot PSL (p < 0,05). Les veaux des vaches du lot FNA ont eu un gain moyen quotidien significativement plus important (669 g/j) que ceux du lot FNL (356 g/j) et ceux du lot PSL (412 g/j). L’utilisation adéquate des fourrages  de ces deux variétés améliorées constitue un moyen d’accroître la production laitière des vaches en saison sèche.

Authors: Adenodi R.A.
Published: August 2023

The focus of miniaturization is the production of small and portable devices that can be carried in the pocket anywhere and anytime.  Small and portable devices that perform multitask such the smartphone requires a portable and efficient antenna that operates in many  frequency bands. A single planar miniaturized Archimedean spiral antenna, which operates in a frequency range that is determined by its  inner and outer radii of its arc, has been adjourned to be a better candidate for these multiple tasks. This study examined the  geometry of a miniaturized Archimedean spiral antenna of varying turns. An inner radius of 4.90 mm and a thickness of 0.0356 mm  suitable for the printed antenna were previously chosen for the study. The length of the arc and the outer radius were determined for  spiral turns ranging from 0.5 to 100 with an incremental step of 0.5. Results revealed the radial distance generating the spiral, the length  of its arc, the outer radius, and the surface area were 4.97 mm, 2 15.51 mm, 4.97 mm and 77.16 mm for 0.5 spiral turns, and 19.12 mm,  7,546.80 mm, 2,849.33 mm and 1,148.64 2 mm for 100 spiral turns. Based on the outer radii, the frequency range of operation will be  between 16.76 MHz and 9.60 GHz. The mathematical functions formulated through curve fitting described the relationship between the  outer radius and arc length with a power function and the number of turns and frequency with an exponential function, while arc length  and radial distance, area and number of turns, and area and pitch angle are described by polynomial functions. It is recommended that  further analysis on the geometry of the minimized Archimedean spiral antenna be conducted.

An azo dye, (E)-4-((4,5-dimethylthiazol-2-yl)diazenyl)-2-isopropyl-5-methylphenol (L1), was prepared by the reaction of 5-methyl- 2-(propan-2-yl)phenol with the diazonium salt of 2-amino-4,5-dimethylthiazole. Characterization was carried out using proton and  carbon-13 nuclear magnetic resonance spectroscopy. Coordination compounds of L1 with Mn(III), Fe(III) and Co(III) in a 1:2 metal to  ligand mole ratio were subsequently synthesized. Corresponding mixed ligand complexes were also synthesized using 2- hydroxybenzoic  acid (L2) as the secondary ligand. The coordination compounds were characterized by electronic and infrared spectrophotoscopy,  magnetic susceptibility measurements, and percent metal composition. Subsequently, in silicostudies were performed based on the  proposed structures of the synthesized compounds to determine their binding affinity and binding site with calf thymus DNA. The results  obtained showed that all complexes achieved octahedral geometry. The results also showed that some of the compounds had better  affinity for CT-DNA than the standard.

Background:Herbal therapies mediate similar functions with those of some well-known drugs. Ginger and aspirin are herbal and drug therapies respectively which are used for the treatment of anti-inflammatory conditions. Non-steroidal medicinal drugs especially aspirin and acetaminophen are usually linked to drug-induced liver injury. Therefore, this research seeks to compare the effect of these two therapies on liver function using aspartate aminotransferase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP) as the biomarkers. The aim of the study was to establish if ginger will offer a better hepatocellular protection considering that the use of aspirin in treating inflammatory disorders is already linked to liver injury.

Methods: AST, ALT, ALP, Total, conjugated and unconjugated bilirubin were assessed in this study using 18 Wistar rats. The animals were divided into three groups (control, ginger and aspirin), six (6) rats per group. The three groups of animals were allowed access to food and water daily throughout the experimental period. Ginger group animals were administered 150 mg/kg dose of aqueous ginger extract while aspirin group of animals also received 150 mg/kg dose of aspirin for four weeks. Control group received normal saline of equal volume with the test groups.

Results: AST, ALT, total and conjugated bilirubin was significantly lower in ginger group compared to aspirin and the control group (P<0.05). However, ALP was significantly higher in ginger group compared to aspirin and the control group (P<0.05). Unconjugated bilirubin showed no significant difference among experimental groups.

Conclusion: Result showed that ginger offered a better hepatocellular protection compared to aspirin group following decrease AST and ALT concentration in the ginger group.

Background: Quercetin is an abundant bio-flavonoid in foods having several biological activities including anti-oxidant properties. However, the toxicity of quercetin may limit its use. Therefore, screening a graded dose of quercetin may be an important step in its use as a dietary supplement. Hence, the effects of graded doses of quercetin on the survival, locomotive behavior and oxidant-antioxidant system in D. Melanogaster was investigated.Methods: A Survival assay was conducted by feeding 50 fruit flies per vial with 50-400 mg/g quercetin-diet for 14 days. For behavioral and biochemical studies, flies were divided into 4 vials (50 flies each) 0, 100, 200 and 300 mg/g quercetin-diet. Flies were treated with vehicle or quercetin for 7 days. Behavioral assessment of negative geotaxis was determined from the climbing activities of flies. Finally, flies were killed, homogenized and centrifuged for supernatant for the assay of Catalase (CAT), Superoxide dismutase (SOD), Glutathione (GSH), Malondialdehyde (MDA) and Total thiol.Results: Quercetin treated groups showed a dose-dependent significant decrease (p<0.001) in survival rate. Climbing activity was unaltered at 100 mg but significantly (p<0.05) reduced at 200 and 300mg quercetin. Total thiol was not significantly altered (p>0.05) across the groups, MDA was reduced (p<0.05) at 300 mg compared to control, CAT activity was significantly increased (p<0.05) at 100-200 mg compared to control while GSH and SOD at 100-200 mg of quercetin increased.Conclusion: Quercetin showed better antioxidant activity at lower doses and adversely affected the climbing behavior and survival rate at higher doses. Therefore, quercetin use should be dose modulated and used with caution.
MasterChef Brasil e a Normalização do Assédio Moral no Ambiente de Trabalho
Authors: Hiller Marcos , Castro Gisela
Published: August 2023

O artigo propõe a reflexão sobre uma certa normalização do assédio moral no ambiente de trabalho com base no programa televisivo MasterChef Brasil, em que um processo de incentivo dessa nociva prática é entregue ao consumo simbólico de espectadores. Por meio de uma metodologia baseada em um quadro teórico de análise, a presente investigação tem como central inquietação um entendimento sobre determinadas lógicas de consumo que estariam alicerçando o mencionado produto midiático. Interessamo-nos sondar por que razões um programa de significativo sucesso de audiência incentivaria uma postura prejudicial às pessoas no ambiente de trabalho. Ainda que de forma cômica e midiatizada, viu-se que um jeito de pensar e de agir decorrente da lógica neoliberal espraiada em nossa teia social serve como um motor que incentiva e apresenta como justificável esse modo de gestão de pessoas no competitivo mercado de trabalho.
