Authors: Ubah Emeka Emmanuel , Ijeh Ifeoma Irene , Egbuonu Anthony Cemaluk C.
Published: May 2024

Background and aims: Insulin resistance (IR) and obesity (Ob) are hallmarks of metabolic syndrome while high-fat diet (HFD) and monosodium glutamate (MSG) consumption have been implicated in both IR and Ob. In current study, hypoglycemic, hepatoprotective, and weight-reducing effects of dietary Vernonia amygdalina (VA) in MSG-intoxicated HFD fed wistar rats was investigated.
Methods: Male wistar rats (36) were randomly allocated into six groups of six rats each, each weighing between 150 and 250 grams on average. The animals were given 5%, 10% dietary incorporated VA (VAHFD), and Orlistat 10 mg/kg for 4 weeks after being treated orally with MSG 8000 mg/kg for the first 8 weeks while on HFD. Changes in the experimental animals' weight, liver histology, total protein and albumin concentrations, and fasting blood glucose concentrations were all noted, and the data was analyzed for statistical significance using appropriate techniques.
Results: Peak fasting blood glucose concentration was recorded for the MSG-only group at the end of the study period while 10% VAHFD was greater than Orlistat 10 mg/kg in reducing it. Hepatotoxicity was observed in rats fed the HFD or HFD +  MSG while the 10% VAHFD was comparable to Orlistat 10 mg/kg in protecting the liver both of which were greater than the 5% VAHFD. The Orlistat group showed a peak reduction in weight gain from week 9 to the end of week 12, followed by the 5% VAHFD > 10% VAHFD.
Conclusions: Following co-intoxication with MSG + HFD, dietary VAHFD was effective in managing hyperglycemia, hepatotoxicity, and weight gain, however, there was no additive effect on toxicity from MSG + HFD co-intoxication on the various studied parameters.

Histamine in fish is formed due to histidine decarboxylase which occurs due to decay by bacteria. In the Maluku community, melinjo leaves (Gnetum gnemon) are used as boiled water in processing rotten fish so that the decay process is inhibited. The compound content of melinjo leaves is tethered to the macromolecule decarboxylase PDB ID (4E1O). Test ligands, seven components of melinjo leaves were optimized using Gaussian. Ligands were bound to the receptor with AutoDock-Vina in grid box size and evaluated with Discovery Studio. The tethering results showed no ligand with affinity exceeding the standard ligand. However, three test ligands were close to the standard such as, dehydrovomifoliol affinity -6.7 kcal/mol, inhibition constant 1.2269 x 10-5. P-cumaric acid and gnetumal affinity -6.1 kcal/mol, inhibition constant 3.3778 x 10-5. Amino acid residue interactions showed hydrogen and hydrophobic bonding. The results of the binding affinity of the test ligand have not been able to be equivalent to the affinity of the standard ligand. However, the dehydrovomifoliol ligand is close to the affinity of the standard with a value of -6.7 kcal/mol and an RMSD of 2 Å. Thus, dehydrovomifoliol compounds from melinjo leaves show antihistamine effects as histidine decarboxylase inhibitors with promising potential.

Increasing human needs cause an increase in production on an industrial scale and can have an impact on increasing contamination of the aquatic environment. Efforts to improve water quality can be made by removing contaminants using renewable activated carbon originating from agricultural waste such as rice husks and teak sawdust. This research aims to examine the adsorption capacity of activated carbon from rice husks (RHAC) and teak sawdust (TSAC) on a binary mixture of Fe(II)/Cu(II) as well as the level of selectivity of each adsorbent on Fe(II) and Cu(II) ions. RHAC and TSAC activated carbon are produced through carbonization processes (T=400 °C, t=60 minutes), reflux (NaOH 2N, T=100 °C, t=120 minutes), chemical activation using H3PO4 (30%, 1:3, b/b) and physics (furnace). The results of this research are that RHAC and TSAC activated carbon have the functional groups O-H (str), C-H (str), C≡C, C=C, C-O (str), and C-O-P (str). The surface character of RHAC and TSAC activated carbon is dominated by the elements C, O, and P. The results of the Fe(II) and Cu(II) ion adsorption treatment using RHAC and TSAC activated carbon follow PSO kinetic modeling with R2 values of 0.9221 and 0.9565 on RHAC and 0.9915 and 0.97 on TSAC. TSAC-activated carbon more selectively adsorbs Fe(II) and Cu(II) ions compared to RHAC-activated carbon with adsorption percentages reaching 97.34% and 87.82%, respectively.
Digitalization of small and medium-sized family enterprises: The key role of succession
Authors: Ricciardi Arcangela
Published: May 2024

Family small and medium-sized enterprises (SMEs) represent a peculiar context for investigating digitalization since the vital link between the family and the business turns into distinctive approaches to innovation relative to nonfamily firms. Although extant literature acknowledges that all firms are increasingly required to respond to the challenges of the digital economy, the current knowledge about how family SMEs pursue digital innovation and how it impacts the organization is still limited. Similarly, understanding if and how succession plays a role in innovation and digital change development in family firms is a topic that needs further investigation. A qualitative study of six Italian family SMEs currently undergoing their digitalization journeys detected three types of digitalization (molt, turmoil, and clear-cut) that are deeply connected with different succession experiences, different levels of business family support, and various levels of strategic planning. The findings highlight the central role of succession and intergenerational dialogue in fostering digitalization in family firms. The paper contributes to the general literature about digital innovation in family SMEs and mainly speaks to that literature focused on the relationship between technological innovation and succession, offering new and deeper insights into the relationship between the family, the person who is in charge of managing digitalization in these firms and the whole digitalization process. Contributions to practice are also outlined: the three types of digitalization represent a valuable tool to sustain consultants and family firms’ owners in digitalizing these organizations.
Influence of Carbon Dioxide on Micro-cracking in Calcite: An Atomistic Scale Investigation
Authors: Wu Fanyu , Hu Manman
Published: May 2024

In candidate formations for geological Carbon Capture and Storage (CCS),
carbonate minerals (e.g., calcite) are ubiquitously presented. The
dynamic process of chemically induced alteration on carbonate-rich
reservoirs due to the injection of supercritical CO2 holds paramount
importance for achieving an economic injectivity and structural
integrity of the system. How carbonate rocks undergo deterioration and
particularly how microcracks develop in the presence of carbon dioxide
remain largely unknown. Here we employ a powerful tool of reactive force
field (ReaxFF) molecular dynamics (MD) simulation, investigating into
the impact of representative CO2 environments on Mode I tensile crack
propagation in calcite at micro-scale. Our simulation results
demonstrate that (1) both dry and wet CO2 environments favor the tensile
crack propagation by lowering the fracture toughness of the pre-existing
crack; (2) the wet CO2 environment promotes the growth velocity of the
subcritical crack compared to the dry CO2 environment, under the same
mechanical loading condition; (3) the interaction between the stressed
crack and the CO2-water mixture diffusing into the crack opening leads
to a small reduction of the system potential energy at an initial stage
of subcritical growth; (4) The crack tip appears to be sharper in both
dry CO2 and wet CO2 environments, albeit at a lower stress intensity
factor than the vacuum case. The atomistic scale findings provide new
insights on the process of subcritical calcite cracking induced by a
reactive environment via CO2 injection, prior to the damage-enhanced
dissolution phase.
Omicron BA.2.86 Pirola nightmare: Empirical formulas and thermodynamic properties (enthalpy, entropy and Gibbs energy) of nucleocapsid, virus particle and biosynthesis of BA.2.86 Pirola variant of SARS-CoV-2
Authors: Popovic Marko , Popovic Marta , Sekularac Gavrilo , Pantovic-Pavlovic Marijana
Published: May 2024

Similarly to a phoenix, SARS-CoV-2 has appeared periodically in waves. The new variants that appeared through mutations have suppressed earlier variants, causing new waves of the pandemic. The Omicron BA.2.86 Pirola variant is the latest in the sequence. An increased infectivity was noticed, which results in rapid spreading, as well as decreased pathogenicity, which results in a lower number of severe cases. However, in the public there is a fear of further development of the epidemic. This analysis was made with the goal to assess the risks in the period of early 2024. Mutations that were developed by the BA.2.86 variant have led to a change in empirical formula and thermodynamic properties. The empirical formula of the BA.2.86 virus particle is CH1.639023O0.284130N0.230031P0.006440S0.003765. It is different than those of other variants of SARS-CoV-2, other virus species and cellular organisms. The driving force for the virus multiplication, Gibbs energy change of biosynthesis of the BA.2.86 variant is ?221.75 kJ C-mol-1. It is more negative than that of its host tissue. According to the biosynthesis phenomenological equation, the more negative Gibbs energy change of biosynthesis allows the virus to achieve a greater biosynthesis rate and hijack the host cell metabolism. However, the Gibbs energy change of biosynthesis of the BA.2.86 variant is similar to those of the CH.1.1 and XBB.1.16 variants. This means that these variants should have similar multiplication rates and thus similar pathogenicity. Therefore, it seems that there is no ground for fear of an extensive spreading of severe forms, but there are reasons for caution and monitoring of the spreading of the epidemic and potential appearance of new mutations. Moreover, unlike the earlier pandemic waves, during the newest pandemic wave, the infections with influenza, RSV and BA.2.86 variant simultaneously appeared, which deserves an analysis.

In this paper, a new split iterative compact difference scheme for a class of
system is constructed. Then, the conservation properties of the scheme are
discussed, and the convergence of the split iterative difference scheme is
analyzed by using the discrete energy method on the basis of the prior
estimation. Finally, numerical experiments verify these properties of the
new scheme. In addition, the numerical results also show the influence of
fractional derivative on the variation of the transport equation.
A remark on a strong minimum condition of a fractal variational principle
Authors: Niu Jing-Yan
Published: May 2024

The fractal variational principle gives a good physical understanding of a
discontinuous problem in an energy way, and it is a good tool to revealing
the physical phenomenon which cannot be done by the traditional variational
theory. A minimum variational principle is very important in ensuring the
convergence of artificial intelligence algorithms for numerical simulation
and image processing. The strong minimum condition of a fractal variational
principle in a fractal space is discussed, and two examples are given to
illustrate its simplicity and feasibility.

Furthermore, the solitary wave solutions are solved by He?s variational
method.
Fractal solitary waves of the (3+1)-dimensional fractal modified KdV-Zakharov-Kuznetsov
Authors: Sun Jianshe
Published: May 2024

In this work, the fractal (3+1)-D modified KdV-Zakharov-Kuznetsov (MKdV-ZK)
model is studied, which can represent weakly non-linear waves under the
unsmooth boundary. With the help of the fractal traveling wave
transformation and the semi-inverse method, a fractal variational principle
is obtained, which is a strong minimum one according to the He-Weierstrass
function. From the variational principle, a fractal solitary wave solution
is obtained, and the influence of un-smooth boundary on solitary waves is
studied and the behaviors of the solutions are presented via 3-D plots. This
paper shows that the fractal dimensions can affect the wave pattern, but
cannot influence its crest value.

Published: May 2024

Background and purpose. Few studies have examined the impact of comorbidity on functional and clinical knee scores after primary total knee arthroplasty (TKA). We compared the effect of having a high Charlson Comorbidity Index (CCI), relative to a low CCI, on changes in the American Knee Society Score (AKSS) functional and clinical scores from baseline to week 52 after TKA in patients with knee osteoarthritis (OA).Methods: This population-based cohort study included 22,533 patients identified in the Danish Knee Arthroplasty Register from 1997 to 2021. Patients were classified as having low, medium, or high comorbidity based on CCI. The outcome was defined as the mean change (from preoperative to 1-year post-TKA) in functional and clinical knee scores measured by the AKSS (0–100). The association was analyzed using multiple linear regression by calculating mean change scores adjusting for sex, age, weight, cohabiting status, and baseline AKSS.Results: The prevalence of patients with low, medium, and high comorbidity was 75%, 21%, and 4%, respectively. The mean change score in functional AKSS for patients with high comorbidity was –6 points (95% confidence interval [CI] –7 to –5) compared with low comorbidity. The mean change score in clinical AKSS for patients with high comorbidity was –1 point (CI –2 to 0) compared with low comorbidity.Conclusion: Patients with knee OA and medium or high comorbidity can expect similar improvements in functional and clinical AKSS after TKA to patients with low comorbidity.

The Policy of Inclusive Education in Indonesia
Authors: Novrizal Nesa , Manaf Sofwan
Published: May 2024

The Policy of Inclusive education plays a crucial role in building an inclusive and equitable society. Quality education obtained by students in general is the same right for children with disabilities. Through Permendiknas No. 70 in 2009, article 1 explains that the education implementation system provides opportunities for all children with disabilities who have the ability and intelligence or have special talents to attend education in an educational environment together with students in general. However, in practice, many schools that organize inclusive education have not fully implemented the policy. This is due to the absence of guidelines for educators in guiding their students. The purpose of this study is to analyze inclusive education policy in Indonesia. This research uses a literature review with documentary techniques as a means of collecting data from trusted sources. The findings of this study are that in implementing inclusive education policies, qualified resources (budget, teaching staff and infrastructure) are needed, interpreting and elaborating policies in the form of regulations to formulate policy implementation, preparing plans for several steps in implementation based on time, place and budget, continuously organizing students, budgets and infrastructure, and providing benefits.

Published: May 2024

Indonesia's rich diversity encompasses various ethnicities, cultures, and religions, with deeply ingrained marriage customs such as the Sasak tradition of Merariq, which reflects a delicate balance between Islamic law and socio-cultural dynamics while facing challenges of persistence and extinction in modern times. This study aims to provide an overview of how local wisdom can be explored from various perspectives, particularly within the framework of Islamic law and the socio-cultural dynamics prevalent in Sasak society. This study employs a qualitative approach with a descriptive analysis method. The research involves data collection through observations in Terong Tawah Village, West Lombok, and interviews with various key figures, including youth leaders, customary leaders, religious leaders, and community members. Additionally, documentation related to the implementation of the Merariq tradition in Terong Tawah Village was conducted to ensure the validity of the obtained data. The research findings elucidate that the Merariq tradition still holds cultural significance but has been simplified to align with Islamic teachings. This tradition involves stages such as midang, memaling, nyelabar, akad nikah, sorong serah, begawe, and bejango or nyongkolan. Implementing the Sasak customary wedding ceremony or Merariq must be harmonized with Islamic understanding to ensure compliance with Islamic principles.

Anthropogenic influences negatively affect the soil properties and woody vegetation in the xerophytic forests and the rare forests of the northern coastal area of the Black Sea. The study was carried out at the properties of soils in the Utrish State Nature Reserve (Russia), which was previously under the influence of anthropogenic impact. Fires, deforestation, and recreational load were selected as the prioritised types of anthropogenic impact in long-term studies with soil (Cambisols) in the Utrish State Nature Reserve, which rapidly lead to the degradation of ecosystems and biodiversity reduction. Soil samples were taken from the 0–10-cm layer in triplicate from each study site. The study site after recreational load has been investigated in 2013, 2015, 2018, 2019, and 2020. The parameters pH, organic carbon content, enzyme activity were studied. Biological properties of soils were found to be more sensitive to changes in characteristics than other soil parameters. For all the studied parameters, there was a decrease in the organic carbon content from 18% to 59% relative to the control. The highest decrease in the indicator was noted for soils after deforestation. Enzymes from the oxidase class recover faster than the hydrolases. Catalase activity for all disturbed soils decreased on average by 13%. Non-significant differences from the control were observed for soils after deforestation and fires. Inhibition of invertase activity was established in soils by an average of 52% after fires and recreational exposure, with an increase in enzyme activity of 77% observed after deforestation. The results can be used to assess effects of the anthropogenic impacts on forests. Biological indicators are good markers of the condition of disturbed soils that could be implicated to determine the prioritised anthropogenic load in the soils of xerophytic forests.

Mango kernel is largely treated as a waste material, but its flour can be used in many foods as a potential replace of wheat flour (WF). Sugar beet molasses (SBM) is a raw material with high possibility to be a functional ingredient in baked commodities. The aims of this research were to process mango kernel flour (MAKF) and sugar beet molasses (SBM) to comparison its chemical composition and minerals content and really to evaluate the quality of MAKF and SBM substituted composite biscuits by investigating chemical composition, minerals content, physical and textural characteristics and sensory evaluation of produced biscuits. The composition of MAKF and SBM showed higher concentration of ash (6.97 and 10.62%, respectively) compared to WF. MAKF showed higher amounts of fat and fiber than WF (3.22 and 2.34%, respectively). Moisture and ash contents of the developed biscuits increased with increasing of MAKF and SBM contents. MAKF increased all minerals content in the all prepared biscuits, while SBM caused an increase only in Na and Fe. Sensory evaluation indicated that 5% SBM and 10% MAKF containing biscuit were the most acceptable to the panelists among composite biscuits.

Several trees are effectively used to biomonitor of trace metals in urban environmental pollution. It gives information about the speciation of trace metals and their transition between organs in the plant. In the wood of the trees, it can be determined which part is formed in which year with the help of organs formed by the effect of seasonal differences. Air pollutants damage to humans and other living things in nature is generally referred to as a sign of pollution. They are released from anthropogenic sources accumulate in the bodies of nearby species over time. They give information about the history of air pollutants due to the accumulation in their wood, inner bark, and outer bark. In this study, organs of Robinia pseudoacacia L., Cupressus arizonica G., and Platanus orientalis L. were analyzed as biomonitors with Inductively Coupled Plasma Mass Spectrometry (ICP-MS). All samples were taken from Kocaeli province industrial zone which has quite a wide industrial area. The concentration of selected trace elements as Iron (Fe), Magnesium (Mg), and Zinc (Zn) their emission caused by industrial activities and transport vehicle density. The results of the study show that Robinia pseudoacacia L. was the most suitable species for Fe, Mg, and Zn concentration levels as a biomonitor.

The angiotensin converting enzyme (ACE) catalyzes the conversion of angiotensin I to a key vasoconstrictor angiotensin II in renin-angiotensin system (RAS), thus playing an important role in both regulating blood pressure and maintaining fluid balance through RAS. Free radicals are continuously produced in the biological system. Therefore, organisms need both exogenous and endogenous antioxidants to guard against the damage caused by these free radicals. In this way, they prevent the occurrence of numerous diseases via protecting cellular components and biomolecules. The aim of the current study was to investigate the ACE inhibitory and antioxidant activities of sulfur compounds. The ACE inhibitory and antioxidant activities of all sulfur compounds increased in a concentration-dependent manner. Among these compounds, methionine had the highest ACE inhibitory and antioxidant activityes based on reducing power, DPPH radical scavenging and ORAC methods. Cystine had the highest ABTS radical scavenging, FRAP and nitrite scavenging activities. However, S-benzyl cysteine and S-phenyl cysteine exhibited the lowest ACE inhibitory and antioxidant activities, respectively. These outcomes indicate that sulfur compounds have both ACE inhibitory and antioxidant activities and may serve as gateways for research toward understanding the beneficial pharmacological effects of sulfur compounds against cell damage caused by oxidative stress.
