CSR communication and internal stakeholders: The overlooked market
Authors: Theron Martha , Cant Michael , Wiid Johannes
Published: June 2024

Corporate Social Responsibility (CSR), the adoption of responsible business practices concerning economic, environmental and social principles, is a tool to develop market value for various stakeholder groups. CSR can create several competitive advantages and should not be seen as a cost, but as a strategic initiative to aid organisations in competing in the market. Effective internal CSR communication to employees enhances an organisation’s corporate identity (CI) – ultimately affecting employees’ attitudes and behaviour. This paper aims to explore South African retail employees’ perceptions of internal CSR communication methods used by their organisations. A dataset of 229 employees participated by completing a computer-aided self-administered survey, which was distributed via LinkedIn. The main findings of the study indicate that employees perceived their organisations to make use of e-mail communication, internal newsletters, web and social media platforms to communicate with them regarding CSR, indicating that other internal communication platforms such as intranet or internal meetings can be utilised more to communicate with employees.
Interrelatedness of the naming of children in the South African cultural context
Authors: Madima Thizwilondi
Published: June 2024

The study seeks to explore the interrelatedness around the naming of children in the traditional societies of Southern Africa. Traditionally, among the Vhavenda, Vatsonga, Bapedi, Xhosa, Zulu, Swati and other various African cultures in Southern Africa, it was the duty of the grandparents to name their grandchildren. The naming was largely influenced by the events which occurred in the family. The study was conducted first to establish the interrelatedness in the naming of children among the multicultural context of traditional societies of Southern Africa, secondly to determine whether the naming has implications to the behaviour and character of the child while they grow. Senior citizens who are knowledgeable were interviewed on what were considered in the naming process and what are the cultural values that are attached to this process. Data was collected using semi structured interviews and analysed thematically. Afrocentric theory was utilised as the basis for the research findings.  The research findings were of paramount importance around some of the individual names among different cultures and the implications of the behaviour of a child when he grows. The paper recommends the reimagining of the spirituality around some individuals names and the naming process, the revival of the traditional naming process is meant for cultural heritage preservation.
Revisiting the January effect anomaly: evidence from international stock markets
Authors: Enow Samuel Tabot
Published: June 2024

A recurring theme in the literature and discussion of stock market analysis is the concept of the January effect which essentially implies buy in December and sell in January. The January effect is based on the perceived seasonality trend where short term investors hope to take advantage of the arbitrage opportunity between December and January. However, this perceived anomaly continues is seen as a myth and has been strongly rejected by many market participants in the current dispensation. The purpose of this paper was to investigate the January effect in the Nikkei 225, JSE, CAC 40, DAX, and the NASDAQ Index from February 2019 to February 2024. A F-test statistics was used to explore the phenomenon. The findings indicated that there is no significant difference between the realised returns in January and those of the other month for the most recent five years. This led to the conclusion that, while the January effect may have been observed, it is no longer evident in financial markets, hence market participants should avoid using this type of arbitrage approach because it may result in massive losses
Reducing prejudice against learners with disabilities in inclusive settings through the Afrocentric model of inclusion
Authors: Mokobane Sonti
Published: June 2024

Attitudinal barriers and discriminatory practices continue to prevent the full participation of learners with disabilities in developmental learning contexts. Although disability has been on the psychological agenda for some time, there is limited empirical evidence on adopting African models to buffer prejudices. This paper addresses this critical gap by examining the experiences of disabled children subjected to prejudices in inclusive settings and the adaptation of the Afrocentric model to buffer those behaviors. The paper was guided by Allport's Social Reflection Theory, which explains why some groups may be targets of prejudice. The exploratory qualitative case study was undertaken in 4 inclusive schools in Gauteng province. Participants were 20 educators and 40 disabled learners in inclusive schools. Purposive sampling was used to choose participants in the study. Data was collected through semi-structured interviews with educators, and the researcher observed the engagement of the educators and 40 disabled learners.  Data collected were analyzed through qualitative thematic data analysis. From the themes that emerged in the findings, the following themes were discussed: advancing the truth in our praxis, fairness, harmony, and humanness. The paper, therefore, recommends that educators apply the practice of including the emerged themes in their learning content for improved grades and low dropout rates.

Exploring the multifaceted dynamics of unemployment in South Africa
Authors: Dunga Hannah , Maloma Ismael
Published: June 2024

This study aims to examine the causes and impacts of unemployment in South Africa using data from the 2022 General Household Survey conducted by STATS SA. Specifically, it seeks to analyze the demographic and socio-economic factors influencing unemployment rates, explore the implications of unemployment on individuals and society, and identify policy implications for addressing this pressing issue. Unemployment remains a significant challenge in South Africa, with persistent high rates that disproportionately affect certain demographic groups. This study addresses the need for an in-depth analysis of unemployment dynamics, providing valuable insights into its causes, consequences, and potential policy interventions. The study utilizes data from the 2022 General Household Survey conducted by STATS SA, encompassing a total population of approximately 18738 households. The dataset offers comprehensive information on employment status, demographic characteristics, education levels, and household income. Employing the statistical software SPSS, employing a combination of descriptive statistics, cross-tabulation, and a binary logistic regression model, the research uncovers significant disparities across demographic groups, shedding light on the challenges faced by individuals at the household level and advocating for targeted policy interventions. Gender disparities emerge starkly, with female-headed households constituting 44% of the sample yet reporting lower employment rates (34.7%) compared to male-headed households (59.6%). Regression analysis confirms this trend, highlighting the gender-based hurdles in accessing employment opportunities. Furthermore, concerning trends in youth unemployment are revealed, with nearly 40% of individuals under 35 reported as unemployed. Regression analysis demonstrates a negative association between age and unemployment, emphasizing the need for targeted youth employment initiatives. Additionally, the study underscores the critical role of education in enhancing employment prospects, with higher levels of education associated with lower unemployment rates. Racial disparities in unemployment rates are also elucidated, with the Black/African population group facing the highest unemployment rate at 52.3%, significantly higher than the Asian/Indian (37.8%) and White (40.4%) population groups. Regression analysis confirms these disparities, necessitating targeted efforts to address structural barriers and promote racial equity in the labor market. The study recommends, implementing gender-sensitive employment policies, enhancing youth skills development programs, and promoting equitable access to education and training opportunities for all groups.
A higher education marketing perspective on choice factors and sources of information considered by prospective first-year students in Botswana
Authors: Zhou Noel
Published: June 2024

The increasing nature of competition in the higher education sector of Botswana means that universities need to craft strategies to be more competitive. The recipe for competitiveness is primarily hinged on the ability of institutions to be cognisant of the factors that influence prospective learners in selecting a university of choice to study. They also critically need to know the sources of information where prospective learners acquire information to redirect their marketing strategies. To achieve these objectives, the purpose of this study was to investigate the factors influencing the choice of university of study as well as their sources of information in influencing choice decision-making. The study followed a qualitative research approach and data was collected using in-depth interviews. Thematic narrative analysis was used to unpack the underlying influences on decision-making. The findings indicate that prospective students get their information from multiple factors. The most influential sources identified are family and friends, career fairs and exhibitions, social media, and to a lesser extent the mass media and promotional materials. The findings also showed that prospective university students’ choice of university is influenced by a variety of factors. These include university location, availability of accommodation, perceptions of university reputation, quality of academic programs, alignment of lifelong interests and desires, and the perception of employability. There are other factors that are less influential as degree of persuasion, funding issues, costs associated with applications as well as government processes and procedures. These findings have potential to influence university marketing strategies and policies in seeking competitiveness and improvement in enrolment numbers.

Authors: Pasacito Mohammad Rikaz Televani , Maya Ariyanti
Published: June 2024

The retail segment has the largest contribution to the total net sales value of Kimia Farma Group, which is run by the company's subsidiary, PT Kimia Farma Apotek (KFA). Kimia Farma's retail segment is experiencing a relatively non-ideal revenue trend from 2017 to 2022. The main challenges faced are the purchasing power of the community, the increasingly fierce level of competition, and risks related to customer loyalty. Based on this background, this study aims to examine the effect of Kimia Farma's image and product attributes on customer loyalty, both directly and indirectly through customer satisfaction. The research was conducted with a quantitative approach at the Kimia Farma Pharmacy in Bandung, with the unit of observation being Kimia Farma pharmacy customers in Bandung City. The sample was 235 respondents, who were taken using the Multistage Random Sampling technique. Structural Equation Modeling was used to conduct causality analysis. The results revealed that: Kimia Farma's image and product attributes play a role in shaping customer satisfaction, but have no direct impact in creating customer loyalty; customer satisfaction plays a role in creating customer loyalty; customer satisfaction mediates the effect of Kimia Farma's image and product attributes on customer loyalty; product attributes have a greater role than Kimia Farma’s image in encouraging customer satisfaction which will create customer loyalty. This research provides managerial benefits for increasing customer loyalty at Kimia Farma Pharmacy in Bandung City, by increasing customer satisfaction, which is supported by the development of product attributes and the image of Kimia Farma.

Published: June 2024

This research aims to determine whether a top cosmetic company’s Beauty for Better Life Women's Empowerment Program (BFBL – WEP) has encouraged women to become entrepreneurs in the micro, small, and medium enterprises (MSME) sector, and identify the various obstacles and challenges they face in navigating their entrepreneurship journey. Launched by the L'Oréal Foundation in 2009 in 27 countries including Indonesia, the BFBL Program believes that a program like this will play a central role in helping vulnerable, underprivileged, or marginalized women regain their self-esteem, develop self-confidence and enhance their well-being. Using a qualitative research design with primary data collected through semi-structured interviews of thirteen (13) female beneficiaries of the Program, the research covered six (6) regions in Indonesia. Additional data was obtained from two (2) more key informants representing the Head of the BFBL Program in L’Oreal Indonesia and a beauty coach. Interviews were done through hybrid methods of offline and online engagements with respondents, enabling reach as well as convenience as the respondents came from different regions across the country. Findings show that the BFBL produces successful women MSME entrepreneurs through a) training in the planning and design of beauty services; b) resource support provides mentoring and coaching, and c) marketing support skills through social media promotion, creating a business portfolio, and learning ethical practices in dealing with clients. Geographical challenges in program implementation as well as logistical capabilities of participants were detected. Implications to organizational practices related to women’s entrepreneurship promotion are presented.

The advancement of mechanization in forestry has increased productivity in the forestry sector, bringing positive and negative impacts that require a deeper understanding for sustainable forest management. This study aimed to apply a simplified instrument for assessing damage and environmental impacts in forest harvesting of commercial eucalyptus plantations, using a combination of methodologies. The methodology used combined interaction networks and impact assessment matrices, carrying out field surveys, transposing them to interaction networks and weighting them through assessment matrices, resulting in environmental indices (ES) for prioritizing actions. The study was conducted on a commercial eucalyptus plantation in the municipality of São Pedro, São Paulo, Brazil. The mechanized harvesting of the area consists of the structure of a module with a mobile unit consisting of a harvester and forwarder. The results indicated that wood transport presented the highest ES, both positive and negative. The most significant negative impacts (ES) were the depletion of water resources and erosion, while the positive impacts included regional development and job creation. The most notable changes, positive and negative, were observed in the physical and anthropic environment, with a lesser impact on the biotic environment.
Protecting Fish Consumers Against Excessive Exposure to Mercury
Authors: Heinonen-Tanski Helvi M
Published: June 2024

Mercury (Hg) analyses in species of fish are performed for two reasons 1) to safeguard human health, 2) to assess environmental quality, since different environmental changes may increase the Hg concentrations in fish. These analyses are important since both natural and human activities can increase these Hg concentrations, which can vary extensively, depending on the species, age and catching location. Unfortunately, humans consuming Hg contaminated fish or other marine foodstuffs cannot taste Hg contamination; this can be only detected by chemical analysis. If the aim of Hg analysis is to protect the health of marine-food consumers, researchers workers must consider the location where the fish were caught and interpret the results accordingly. Health and environmental officials must appreciate that in specific places many local people may have a daily diet almost entirely consisting of fish or other marine foods, and these individuals should not be exposed to high concentrations of Hg. Regional and national health and environmental officials should follow the guidance of international organizations when drawing their final conclusions about whether or not the products are safe to eat.
Enhanced Cortical Plasticity in Alzheimer’s Disease: Exploring ccPAS Potential.
Authors: Di Fazio Chiara , Tamietto Marco , Stanziano Mario , Nigri Anna , Palermo Sara
Published: June 2024

Age-related brain deterioration and Alzheimer's disease (AD) pose major challenges as misfolded proteins are deposited in the brain, leading to a decline in cognitive abilities and disruption of neural networks crucial for memory. This article addresses the impact of disrupted spike-timing-dependent plasticity (STDP) mechanisms in Alzheimer's disease and highlights the role of Transcranial magnetic stimulation (TMS) in the study of cortico-cortical spike-timing-dependent plasticity. Amidst this adversity, the role of STDP emerges as a key player in memory formation by synchronizing neural activity. Progressive neuronal dysfunction decreases neural plasticity and impairs manual dexterity and speed, echoing more general problems in elderly people. The findings highlight the potential of neurally-driven cortico-cortical paired associative stimulation (ccPAS) to revitalize neural plasticity and improve motor performance in elderly people, bridging the gap between age-related challenges and Alzheimer's research. This work opens a door to potential rehabilitation strategies for aging populations by unlocking the aging brain's ability to improve motor performance.

Authors: Yamanushi Ayumi , Shimada Takeshi , Koizumi Ami , Kobayashi Masayoshi
Published: June 2024

In schizophrenia, cognition is closely linked to social competence and influences long-term prognosis. Thus, treatment should target cognitive improvement to enhance the patients’ societal adaptation. This study evaluated the effects of computer-assisted cognitive remediation therapy (CR) using RehaCom® on cognition in patients with schizophrenia. Thirty patients were randomized, with 15 assigned to the CR group and treatment usual care (TAU) and 15 to the TAU alone groups. Over 12 weeks, patients received CR twice weekly, including two computer sessions and one verbal session. Outcomes measured were cognition using the Brief Assessment of Cognition in Schizophrenia and Schizophrenia Cognition Rating Scale, intrinsic motivation using the Quality of Life Scale and Intrinsic Motivation Inventory, psychiatric symptoms using the Positive and Negative Syndrome Scale, negative symptoms using Scale for the Assessment of Negative Symptoms, and functional level using modified Global Assessment of Functioning scale for Functioning. The CR + TAU group demonstrated considerable improvements in cognition, intrinsic motivation, negative symptoms, and functional level compared to the TAU-alone group. These findings indicate that the CR using RehaCom® enhances cognition and other outcomes in schizophrenia.

If the cells undergo changes and become cancer cells, the information stored in the brain and the electromagnetic signals inside and outside it change. Based on these changes, tumor and cancer formation can be detected in the early stages, and by storing the right information in the brain; it created the context for sending appropriate messages to return the cells to a normal state.
Pan-Evo: The Evolution of Information, and Biology’s Part in This
Authors: Sherwin William Bruce
Published: June 2024

Simple Summary: 200 words Will biology, including humans, benefit or harm from new developments in information such as artificial intelligence (AI). First, are biology and information different? Life is an ordered form that can reproduce, maybe with variation; and any ordered arrangement, biological or not, potentially contains information. There have been ordered forms since earth was just a ball of chemicals, and some such chemicals can reproduce. So biological and non-biological information might be components of a unified process, ‘PanEvolution’ or ‘Pan-Evo’, based on the same four operations for living or non-living entities - Innovation; Transmission and replication; Adaptation; and Movement. This can produce separate groups called ‘species’. In a current Panspeciation event, information held in biology - especially our brains - is moving into its own environment. Harm to biology might be minimal if humans and AI both behave intelligently, because vastly different environments are optimal for humans and machines containing AI. This would be the first speciation-like event involving humans for millennia, but will not be particularly hostile to humans, if humans learn how to evaluate information and cooperate, to minimize the effect of both human stupidity and artificial simulated stupidity (ASS – a failure of AI). Abstract: 200 words Many people wonder whether biology, including humans, will benefit or harm from new developments in information such as artificial intelligence (AI). Biological and non-biological information might be components of a unified process, ‘Pan-Evolution’ or ‘Pan-Evo’, based on four basic operations – Innovation, Transmission, Adaptation, and Movement. Pan-Evo contains many types of variable objects, from molecules to ecosystems. Biological innovation includes mutations and behavioural changes; non-biological innovation includes naturally-occuring physical innovations, and innovation in software. Replication is commonplace in and outside biology, including autocatalytic chemicals, and autonomous software replication. Adaptation includes biological selection, autocatalytic chemicals and ‘evolutionary programming’ used in AI. Extension of biological speciation to non-biological information, creates a concept called ‘Panspeciation’. Panevolution might benefit or harm biology, but harm might be minimal if AI and the humans behave intelligently, because humans, and the machines in which AI resides, might split to the vastly different environments that suit them. That is a possible example of panspeciation, and would be the first speciation event involving humans for thousands of years. This event will not be particularly hostile to humans, if humans learn to evaluate information and cooperate better, to minimize both human stupidity and artificial simulated stupidity (ASS – a failure of AI).

Prenatal Sonographic Diagnosis and Postnatal Outcomes of Fetal Intracranial Hemorrhage: Two Case Reports
Authors: Vu Thi Hai Yen
Published: June 2024

BackgroundIntracranial hemorrhage (ICH) in pregnancy, estimated at 1 in 10,000 cases, presents significant diagnostic challenges prenatally despite advanced imaging techniques such as ultrasound (US) and MRI. Detecting ICH is crucial for pregnancy management and future treatment decisions aimed at improving fetal survival and reducing brain damage. This report presents the diagnosis and outcomes of two cases of prenatal ICH.Cases presentationThe first case involves a 30-year-old pregnant woman with irregular prenatal care diagnosed with ICH at 32 weeks of gestation via US and MRI. She chose to continue the pregnancy, delivering a 3160g male infant at 36 weeks via cesarean section. Following NICU care including resuscitation and ventriculoperitoneal shunt placement, the infant was discharged. Subsequent examinations showed a reduction in ventricle size. In the second case, a 27-year-old woman taking acenocoumarol for a mechanical heart valve developed fetal subdural hemorrhage detected by US and MRI. She opted to terminate the pregnancy, resulting in a stillborn male infant weighing 1530g.ConclusionFetal ICH presents with varying severity and prognostic implications, diagnosed and graded using US. Fetal cranial MRI may help clarify the etiology. Management remains controversial, with termination of pregnancy potentially warranted in severe cases due to poor prognosis. Further research is needed to refine management and improve outcomes in fetal ICH.
Anti-inflammatory Potential of Pygeum africanum Bark Extract: An In Vitro Study of Cytokine Release by Lipopolysaccharide-Stimulated Human Peripheral Blood Mononuclear Cells
Authors: Villar Agustín , Silva-Fuentes Fredy , Mula Anna , Zangara Andrea
Published: June 2024

Pygeum africanum bark has been shown to inhibit the production of pro-inflammatory prostaglandins in the prostate and reduce the production of leukotrienes and other 5-lipoxygenase (5-LO) metabolites. It has been suggested that inflammation plays an important role in the pathophysiology of benign prostatic hyperplasia (BPH). In clinical trials, P. africanum improved the symptoms and objective measures of BPH. This in vitro study aimed to assess the anti-inflammatory potential of a proprietary Pygeum bark standardized extract (Prunera®) on cytokine release by lipopolysaccharide-simulated human peripheral blood mononuclear cells (PBMCs). PBMCs were obtained from four donors and a bead-based assay (ProcartaPlex™ panel) was used for the detection and quantitation of cytokines. Pygeum africanum bark standardized extract (PABE) showed the following effects: IL-2 was lowered in all donors in absence of a clear dose–response relationship; IL-4, IL-5, IL-6, IL-9, and IL-13 levels were decreased in most donors; IL-22 levels seemed to be suppressed only for donor 4 at lower and medium concentrations; and IL-27 and levels of TNF-α decreased at all PABE concentrations in all donors. The anti-inflammatory effect of PABE supports the potential use of this natural compound in the management of BPH and other conditions in which pro-inflammatory cytokines are involved in their underlying pathophysiological mechanisms.

Early childhood may be a stressful period for families with a significant impact on parents’ mental health and the child’s healthy development. The goal of the SKKIPPI cohort study was to assess the occurrence and determinants of psychosocial stress and mental health disorders in parents as well as in their offspring in early childhood in three German regions.
Based on random samples from three residents' registration offices, parents with infants up to 12 months of age at the time of sampling, were invited to participate in the study. A screening online questionnaire was newly developed, available in four languages, to assess common psy-chosocial stressors and mental health problems of parents with small children.
The study enrolled 4,984 mothers and 962 fathers. The most common potential psychosocial stressors at baseline were professional problems (mothers 22%, fathers 33%), lack of social sup-port (20%, 14%), and severe, negative experiences in childhood (22%, 16%). Obses-sive-compulsive thoughts (21%, 16%), depressive (9%, 9%) and anxiety symptoms (11%, 7%) were the most frequently reported mental health problems by both parents. Regulatory prob-lems of the child were reported by between 1.5% and 5.1% of parents.
The SKKIPPI study showed that a substantial proportion of parents are burdened by psychoso-cial problems and suffer from mental health problems in the first years after birth. Early pre-ventive and low-threshold support measures should be available in the health and social care system. The newly developed questionnaire can be used to screen in the relevant populations in order to avoid disturbances in the mother-child attachment.
Impact of Dispersion Methods on Mechanical Properties of Carbon Nanotube (CNT)/Iron Oxide (Fe3O4)/Epoxy Composites
Authors: Ali Zulfiqar , Yaqoob Saba , D'Amore Alberto
Published: June 2024

Integrating nanomaterials like carbon nanotubes (CNTs) and iron oxide (Fe3O4) into epoxy composites has significant interest due to their potential to enhance mechanical properties. This study evaluates the impact of dispersion quality on the mechanical performance of CNT/Fe3O4/Epoxy composites, comparing stirring and sonication methods at three different loadings: 0.1, 0.3, and 0.5 wt.%. Tensile testing revealed that sonicated composites consistently outperformed stirred composites, with a significant increase in elastic modulus and ultimate tensile strength (UTS). However, fracture strain decreased in both composite types compared to pure epoxy, with sonicated composites experiencing a more significant reduction than stirred composites. These results underscore the importance of high-quality dispersion for optimizing mechanical properties.
A study of Tennis Tournaments by Means of an Agent-Based Model Calibrated with a Genetic Algorithm
Authors: Prestipino Salvatore , Rapisarda Andrea
Published: June 2024

Direct competitions involve competitors that mutually contend for the same resource or objective. A controlled, well-documented, and data-rich field involving direct competition is represented by sports. Usually the winner of sports competitions is believed to be the one with the greatest talent, however, there are other factors that contribute to the outcome of a competition, there are in fact random, unpredictable events that can change the outcome of a competition. For this reason, if one wants to understand the properties of a competition is necessary to have a method to evaluate the importance of the talent or aptitude of a competitor, as opposed to the importance of chance, in determining the outcome of the competition itself. In this work we study the sport of tennis using the data obtained from the Association of Tennis Professionals (ATP) tournaments. We construct an agent-based model that is able to produce data analogous to the real one; this model depends on three parameters, the talent, the action of chance, and the weight of talent. In particular, we don't fix the values of these parameters and we fit the model results using a genetic algorithm, in this way, we study all the possible combinations of parameters, in the parameter space, that are able to reproduce the real systems data. We show that the model fits well the real data only for limited regions of the parameter space. On these limited regions of the parameter space are possible further optimization of the model results, limiting the values of parameters. In this way, our agent-based model, by means of this genetic algorithm calibration, is able to provide us with useful information without any a priori constraints.

Published: June 2024

An emissions baseline for a city is the foundation to building an informed clean air action plan. This includes an understanding of the sources and their intensities to device cost-effective measures with the least health impacts. In an urban environment, emissions from road transport is one of the major contributors to the air pollution problem, and accounting for this sector requires a detailed profile of in-use vehicles, covering their age-mix, usage, and fuel economy. In this paper, we present a simplified framework to survey at select fuel stations to establish the necessary inputs and use them to build a localized vehicle emissions inventory. The methodology is illustrated with an application in the city of Patna, India. Here, the FuSS was employed to profile the in-use passenger vehicle characteristics by 19 trained students, over nine days and at ten fuel stations, to collect 9,775 survey points. The methodology outlined in this paper, along with the tools and training framework, is also replicable in settings other than the fuel stations.

SARS-CoV-2 is an obligatory intracellular pathogen that requires of a lipid bilayer membrane for its transport, to build its nucleocapsid envelope and to fuse with the host cell. The biological membranes are constituted by phospholipids (PLs) and vitamin E (Vit E) protects them from oxidative stress (OS). The aim of this study was to demonstrate if the treatment with Vit E restores the modified profile of the FA in PLs in serum from patients with coronavirus disease-19 (COVID-19). We evaluated Vit E, total fatty acids (TFA), fatty acid of the phospholipids (FAPL), total phospholipids (TPLs), 8-isoprostane, thromboxane B2 (TXB2), prostaglandins (PGE2 and 6-keto-PGF1α), interleukin-6 (IL-6) and C-reactive protein (CRP) in serum from 22 COVID-19 patients before and after treatment with Vit E and compared the values with those from 23 healthy subjects (HS). COVID-19 patients showed a decrease in Vit E, TPLs, FAPL and TFA in serum in comparison to HS (p≤0.01) and Vit E treatment restored their levels (p≤0.04). Likewise, there was an increase IL-6 and CRP in COVID-19 patients in comparison with HS (p≤0.001) and the treatment with Vit E decreased their levels (p≤0.001). Treatment with Vit E contributes to restore the modified profile of the PLs in the SARS-CoV-2 infection and this leads to a decrease of OS and of the inflammatory process.

Published: June 2024

This study examines if enterprises’ digital transformation enhances their sustainable development capabilities and reduces carbon emissions, thus enhancing carbon neutrality performance and implementing the "dual-carbon" strategy. It specifically explores the impact of Chinese firms’ digital transformation on carbon neutrality performance in 30 provinces and municipalities in China from 2011 to 2021. Based on the Difference-in-Difference method and spatial econometric modeling, this study finds a U-shaped relationship between enterprise digital transformation and carbon performance, with spatial spillover effects. It also finds that converting environmental charges into taxes can significantly improve carbon performance. In terms of the mechanism of action, digital transformation affects carbon performance by influencing energy use efficiency and adjusting the level of industrial structure advancement and rationalization. In terms of heterogeneity, this U-shaped relationship exists only in the eastern and central regions, and the significance is more substantial in the east; in addition, the impact of enterprise digital transformation on carbon performance is more evident in regions with higher R&D intensity and higher economic development levels. These findings imply that the government should further encourage and guide enterprise digital transformation, monitor the effects of environmental protection policies and select and implement carbon emission reduction strategies according to local conditions to improve carbon performance.

Published: June 2024

In this work, we consider the properties of the two-term Machin-like formula and develop an algorithm for computing digits of π by using its rational approximation. In this approximation, both terms are constructed by using a representation of 1/π in the binary form. This approach provides the squared convergence in computing digits of π without any trigonometric functions and surd numbers. The Mathematica codes showing some examples are presented.

(1) Background: Gamma-aminobutyric acid (GABA) is one of the inhibitory neurotransmitters with beneficial effects including sedative property. However, despite various clinical trials, scientific evidence regarding the impact of orally ingested GABA, whether natural or synthesized through biological pathways, on sleep is not clear.; (2) Methods: The present study work evaluated GABA-A biding affinity of GABALAGEN(GBL), a low-molecular-weight collagen infused with GABA, through receptor binding assays. The sedative effects of GBL were investigated through electroencephalography (EEG) analysis in the electro foot shock (EFS) stress-induced sleep animal model and then we examined the expression orexin, GABAA receptor in the brain region using immunohistochemistry.; (3) Results: We found that on the binding assay, GBL displayed high affinity to GABAA receptor (IC50 value, 31.5µg/mL)). Also, after treatment of GBL, percent of total time of REM and NREM were significantly and dose-dependently increased compared to the Con group. Consistent with behavioral results, the GBL-treated groups showed that the expression of GABAA receptor immune-positive cells in the VLPO were markedly and dose-dependently increased compared to the Con group. Also, the GBL-treated groups showed that the expression of orexin immune-reactive cells in the LH were significantly decreased compared to the Con group.; (4) Conclusions: In conclusion, GBL showed efficacy and potential to be used as an anti-stress therapy to treat sleep deprivation through antagonism of GABA receptors and consequent inhibition of orexin activity.
Alternative Structure-Function Insight Into Angiotensin II Positions 3 and 4 Based on Investigations of Analogues Containing Unconventional Amino Acid Derivatives
Authors: Nakaie Clovis Ryuichi , Barros Alexandre De Jesus
Published: June 2024

A novel investigation into the structure-function relationship was undertaken to enhance understanding of the mechanism of action of the vasoactive peptide angiotensin II (AngII) using unconventional substitutions such as AIB (α-aminobutyric acid), CHA (cyclohexylalanine acid), IAP (isonipecotic acid), TOAC (2,2,6,6-tetramethylpiperidine-1-oxyl-4-amine-4-carboxylic acid) at position 3, and DMT (2,6-dimethyl-Tyrosine) at position 4. Biological potency assays were conducted on guinea pig ileum, and structural features were analyzed using circular dichroism (CD) and molecular dynamics (MD).
CHA3-AngII and AIB3-AngII analogs retained some agonistic activity, whereas IAP3-AngII and TOAC3-AngII derivatives were inactive. CD results indicated low conformational flexibility for AIB3-AngII and CHA3-AngII, and greater conformational restrictions for IAP3-AngII and TOAC3-AngII, consistent with computational modeling analyses. DMT4-AngII exhibited significant agonistic activity compared to the inactive Phe4AngII. Molecular modeling suggested a potential interaction between the hydroxyl group of Tyr4 and the amide bond between positions 7 and 8. AngII showed greater conformational restriction compared to DMT4-AngII and Phe4-AngII, underscoring the importance of tyrosine at position 4.
Robot-assisted Augmented Reality (AR)-guided Surgical Navigation for Periacetabular Osteotomy

Published: June 2024

Periacetabular osteotomy (PAO) is an effective approach for surgical treatment of developmental dysplasia of the hip (DDH). However, due to the complex anatomical structure around the hip and limited field of view (FoV) during the surgery, it is challenging for surgeons to perform a PAO surgery. To solve this challenge, we propose a robot-assisted augmented reality (AR)-guided surgical navigation system for PAO. The system mainly consists of a robot arm, an optical tracker, and a Microsoft HoloLens 2 which is a state-of-the-art (SOTA) optical see-through head-mounted display (OST-HMD). For AR guidance, we propose an optical marker-based virtual-physical registration method to estimate a transformation from the optical tracker coordinate system (COS) to the virtual space COS, such that virtual models can be superimposed on the corresponding physical counterparts. Furthermore, to guide the osteotomy, the developed system automatically aligns the bone saw with osteotomy planes planned in preoperative images, and then provides surgeons with not only robot assistance but also AR guidance. Comprehensive experiments were conducted to evaluate both virtual-physical registration accuracy and osteotomy accuracy of the developed navigation system. The proposed virtual-physical registration method achieved an average mean absolute distance error (mADE) of 1.96 ± 0.43 mm. The developed system achieved an average distance deviation of 0.82 ± 0.17 mm and an average angular deviation of 3.77 ± 0.85 . Experimental results demonstrated high virtual-physical registration accuracy. The sub-millimeter distance deviation demonstrated the osteotomy accuracy of the proposed system.
