Published: June 2024

Infections and cancers are one of the most serious concerns to humankind, causing a massive amount of impairments and fatalities. Quick detection and treatment of infections and cancers allow for a better knowledge of their pathology. The optimum strategy for detecting pathogens needs to be quick, precise, sensitive, and cost-effective. PCR-mediated methods have additional restrictions including extremely specialized equipment, reagents, well-trained staff, and well-established facilities. There are three novel CRISPR-mediated methods, including SHERLOCK, DETECTR, and CUT-PCR, developed for precise diagnosis. These new techniques can be attached to other diagnostic methods for achieving more precise strategies. SHERLOCK, DETECTR, and CUT-PCR are potential technologies for the quick detection and diagnosis without complicated processing, however, these are still in the early stage. In the review, we briefly introduced these three CRISPR-mediated diagnostic methods.

According to research, corn husk waste contains alkaloid compounds with antioxidant activity of 43.13% which functions to increase collagen production, reduce fine lines and wrinkles, reduce black spots and treat acne. Meanwhile, the eggshell membrane contained in eggshells contains collagen and protein which can help rejuvenate the skin and increase skin elasticity. Utilizing the potential of organic waste corn husks and eggshell membranes as a source of antioxidants and collagen for raw materials for skin care cosmetics has advantages in terms of economics and environment. Because it can reduce waste generation, it can also be economically profitable. The aim of this research was to determine the physical quality of a peel-off mask made from corn husk extract and eggshell membrane powder. As well as identifying antioxidant activity and collagen mask content in peel-off masks. Peel-off masks from these two materials meet the physical quality test for peel-off masks. With a pH ranging from 6.5-6. Spreadability between 4.2-5.5 cm. Drying time ranges from 14-24 minutes. The IC50 value of the peel off mask is 7785.87 ppm which shows that there is no antioxidant potential in the product. Identification of collagen using the FTIR method indicates the presence of a secondary structure of â-sheet protein which shows that the existing collagen has not been degraded into gelatin

Published: June 2024

Enormous development of neuroimaging technologies, and subsequently of research methods, opened new era of in vivo research of the white matter anatomy. This review analyzes recent connectomics and imaging data about short association fibers of the frontal lobe, and relates it to current status and to further development of anatomical terminology. In some recent terminologies, such as in Neuroanatomical Terminology, or in Terminology of German Anatomical Society, under the section Fibrae associationis lobares Fasciculus frontalis obliquus, Fasciculus frontalis orbitopolaris and Fasciculus frontomarginalis have been listed. Also, in this review anatomy of the potential candidates for adding into new terminologies is described, such as Fronto-parietal U-tracts, Fronto-insular tracts, and Frontal longitudinal fasciculus system. Suggestions considered in this review are related to our research of human brain morphology in order to overcome the lack of postmortem brain specimens, to contribute to the linking of different data, and to enable better morphological correlations.  
Electric charges of the lipid headgroup modulate Melittin adsorption to lipid vesicle membranes

Peptide lipid membrane interactions are modulated by factors such as
peptide hydrophobicity and the electric charge of both the peptide and the membrane
surface. We investigated the influence of lipid headgroup charge on the adsorption of
Melittin (Mel) on the surface of artificial lipid vesicles in conditions that mimic the
interaction with biological cells, such as ionic strength, pH, and peptide concentration.
Taking advantage of Mel TRP residue fluorescence, we used several fluorescence
techniques (FRET, fluorescence quenching, time-resolved fluorescence) to investigate
Mel adsorption on the surface of the DMPC and DMPC with fractions of positively
charged lipids (EPC) or negatively charged lipids (DPPG) vesicles. Our results show
that the DMPC:DPPG vesicles allow a deeper localization of TRP residues in the lipid
membrane, proven by the blue shift of the TRP emission spectrum and the exclusion
radius evaluated from FRET. We also showed that even for positively charged surfaces
Mel tends to adsorb on the lipid surface. The results were confirmed indirectly by
quencher accessibility to TRP. Finally, we discuss the results in correlation to the Mel
effects on biological cells

A ten times smaller version of CPC Global Unified Gauge-Based
Daily Precipitation Dataset (1979–2021) is released and described in this paper. Its
usability is tested and proved, firstly, by illustrating that the transition to the derived
smaller dataset is a case of Pearson correlation transitivity starting with the scale of
global yearly data and, secondly, by using the original correlation performance
criterion that the original dataset satisfies relative to the set of global actual
measurements on the record. Subsequently, the daily, weekly, and monthly data cases
are considered and discussed. The dataset is (re)structured for parallel processing in
Matlab and R from the level of global daily data. Considering the above arguments
and its reduced size, the derived dataset is appropriate to be used with Matlab and R
as a replacement for the original dataset, especially for the case when much faster
exploratory master-slave parallel and distributed Matlab and/or R tasks will run over
locally distributed data on the slaves.

Aquatic ecosystems are perpetually exposed to anthropogenic sources of pollution, wherein the quality of subterranean and surface waters undergoes influence from both natural and anthropogenic processes. This interaction results in environmental predicaments and, occasionally, environmental crises. Small rivers, in particular, bear a pronounced impact from human interventions on the environment. The investigation undertaken by the researchers commenced in 2021 with the primary objective of scrutinizing the ecological condition of the Irsha River. Regrettably, due to the military aggression of the Russian Federation, the regions through which the river courses were temporarily occupied, subjecting it to considerable anthropogenic disturbances. Specifically, two bridges spanning the Irsha River in the Malyn area were demolished, and military operations transpired along the riverbanks, leading to the accumulation of damaged military equipment. Consequently, it was deemed imperative during the course of our study to conduct an analysis of the natural water in the Irsha River subsequent to the military activities. The outcomes of a comprehensive assessment of surface water quality, employing a graphical method, revealed that, during the period of 2021-2022, the river waters within the Irsha River exhibited an overall failure to meet quality standards in both monitoring locations. Elevated values of Maximum Permissible Concentration (MPC) exceeding the norm were noted for the Chemical Oxygen Demand (COD) indicator, the dissolved oxygen indicator, as well as the general iron and iron of permanganate oxidizability parameters in both samples. The highest degree of pollution was discerned in the Malyn Reservoir, whereas the Irsha Reservoir manifested comparatively lower pollution levels in the aquatic environment.

Published: June 2024

This paper aims to investigate some of the most important factors of tourism demand in Southern European Countries. The System Generalized Method of Moments is applied to a panel of 15 relevant tourist generating countries, for the period from 2005 to 2021. The considered explanatory variables follow the expected signs and have statistically significant effects on international tourist arrivals. The results suggest that tourism demand is negatively affected by bilateral distance, and global health emergencies such as COVID-19 pandemic. Moreover, lagged tourist arrivals, per capita income in origin countries, and the existence of a common border have a positive effect on the considered dependent variable.

Published: June 2024

Objective: Heart failure is a major health problem worldwide. We report the initial experience of a new left ventricular assist device (LVAD) Heartcon—a centrifugal pump of magnetic-fluid suspension rotor integrated with the pump and machine. From September 2020 to March 2023, HeartCon was implanted in a total of 78 cases throughout China, 27 were implanted in TEDA International Cardiovascular Hospital. Methods: The patient data collected from the medical record included patient demographics, surgical and cardiopulmonary bypass (CPB) data, doses of transfused red blood cells, mechanical ventilation time (h), intensive care unit (ICU) stay time (d), and cardiac function indices assessed by echocardiography, 6-minute walk tests, and N-terminal pro brain natriuretic peptide (NT proBNP) values. Results: All patients were in New York Heart Association (NYHA) grade IV before surgery and 21 had a dilated cardiomyopathy. All patients survived the surgery. One patient underwent heart transplantation 10 months after the implantation. Eight patients reported adverse event events. The duration of mechanical ventilation after operation was 37.8 ± 52.0 h. The incidence of hemorrhagic stroke was 7.4% and the incidence of mediastinal infection was 7.4%. At 90 day followup, 25 patients were in NYHA grade I and the other 2 patients were in grade II. Conclusion: We conclude that HeartCon implantation is a safe and useful LVAD for treatment of end-stage heart failure. It provides a shorter duration of mechanical ventilation time, and a lower incidence of hemorrhagic stroke and mediastinal infection.

Published: June 2024

This journal reviews Islamic law regarding diamond mobile legends as a wedding dowry. This research aims to find out diamond mobile legends as a dowry from the perspective of Islamic law. This type of research is qualitative research through literature studies in journals and theses. The result of this research is that Mobile Legends diamonds cannot be used as dowry because the top up law in Mobile Legends is that it is not allowed to neglect the player and is against Sharia benefits, whereas according to Sharia law, dowry must be Sharia benefits. In the context of Islamic law, the use of Mobile Legends diamonds as a wedding dowry requires careful consideration. Therefore, the author chose to analyze the title. The law of dowry is obligatory as stated in the Ash-Shafi'i School of thought which defines dowry as something that is obligatory because of marriage or the legal fulfillment of the right to sexual intercourse, because of forced deprivation of the right to sexual intercourse on the part of the husband, or because of khulu' and testimony. So, what is required from men for women is called dowry. Furthermore, the term dowry includes those required because of a valid marriage and those required because of sexual intercourse, whether in a broken, questionable or forced contract. So the meaning of dowry in terms of meaning is more precise than the meaning of dowry according to sharia terms, because the meaning of dowry according to sharia includes what is given to women to justify having sexual relations because of doubts and so on. According to the author, the law on mobile legends diamonds as a wedding dowry is invalid because the mobile legends top up law itself is not permitted because it contains waste and elements of a zero sum game (betting money) while the terms of the dowry are something that is sharia.

Published: June 2024

Objectives: To explore the molecular network of the thyroid in aged macaques with bone marrow mesenchymal stem cells (BMMSCs) treatment. Methods: According to age, healthy rhesus monkeys were divided into 3 groups: young group, adult group and elderly group. Among elderly group, it was sub-divided into 2 groups, in which the one is control group while the other was subject to intravenously injection of BMMSCs (treatment group). Single-photon emission computed tomography/computed tomography (SPECT/CT), serological thyroid function test and thyroid hematoxylin-eosin (HE) staining and immunohistochemical analysis were conducted to investigate the changes of thyroid structure and function in the process of aging and with the treatment of BMMSCs. Transcriptome sequencing was used to explore the genic transcriptome of thyroid in macaques, and combined with bioinformatics to analyze the potential targets and signaling pathways related to thyroid aging, so as to predict the network of BMMSCs against thyroid aging. Results: Aged rhesus showed increased 18F-FDG uptake values and decreased CT values in thyroid, accompanied with a reduction in thyroid technetium uptake rates, decrease in free thyroxine (FT4) and free triiodothyronine (FT3), as well as observable degradation and abnormal fibrosis with high thyroid transcription factor-1 (TTF-1) staining intensity, indicating that thyroid degeneration occurred in aged rhesus. By setting the conditions of |log2FC| ≧ 0.6 and p < 0.05, 529 differential genes were screened in macaques across different ages, and 191 differential genes in macaques before and after stem cell treatment. A total of 66 intersecting genes were screened out. It showed that 2 genes exhibited an up-regulated trend with the age and treatment; 15 genes showed an up-regulated trend with age while a down-regulated trend after stem cell treatment; 49 genes were down-regulated with the age, which were up-regulated after treatment. Gene Ontology (GO) analysis found that the differential genes were mainly enriched in the processes of B cell proliferation, T cell co-stimulation, and T cell proliferation. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis found that the differential genes were mainly involved in primary immunodeficiency, T cell receptor signaling, cell adhesion molecules and other pathways. Conclusions: BMMSCs may play an anti-aging effect on the thyroid by immune response and cell metabolism through multiple targets and multiple pathways.

While the Indian mutual fund industry has registered a six-fold increase in AUM over the last 10 years, it is yet to emerge as the preferred investment choice for retail investors in India. More than 50 years have gone by since UTI started its first sale in July 1964, and we believe that in the next few years, the industry will perform closer to the original mandate of encouraging and mobilizing savings of small investors. The confluence of emerging technology and enabling regulation will facilitate the industry to broaden and deepen its reach amongst retail investors. We believe that these enablers will help the industry to increase its customer base in a cost-effective manner from 42 mn retail accounts and increase their ticket size. While these measures will enable customer acquisition, AMCs need to focus on retaining customers through sale of simpler products, demonstrating better fund performance, better service quality and deployment of analytics.

Authors: Minh Thuy Nguyen Thi , Thanh Le Quang
Published: June 2024

Mean-square relative displacement (MSRD) of Iron (Fe) has been investigated in the anharmonic X-ray absorption fine structure (XAFS) theory. The thermodynamic parameters are derived from the influence of the absorbing and backscattering atoms of all their nearest neighbors in the crystal lattice with thermal vibrations. The MSRD is calculated in explicit forms using the classical anharmonic correlated Einstein model. The numerical results of Fe in the temperature range from 0 to 600 K are in good agreement with those obtained by the other theoretical models and an experiment at several temperatures. The analytical results show that the present model is useful in analyzing the experimental XAFS data of Fe.

In this study, perovskite BaTiO3 and SrTiO3 catalysts were prepared using the sol-gel method for oxidative coupling of methane (OCM). Characterization of catalysts was investigated by X-ray diffraction for crystal properties, physical N2 adsorption to determine specific surface area, and temperature-programmed techniques to examine the redox properties and acid–base strength. The results showed that at any reaction temperature, the methane conversion of BaTiO3 was consistently higher than that of SrTiO3. This may caused by BaTiO3’s better reducibility detected by H2-TPR experiments. Moreover, the selectivity of BaTiO3 (25 – 30%) was much greater than that of SrTiO3. Perhaps the abundant lattice oxygen may explain the excellent C2H4 selectivity obtained for BaTiO3.

In this study, nanocomposite GO/Fe3O4/CS (GFC) was prepared for adsorption of heavy metals like Cd2+, Ni2+, CrO42- in the aquatic environment. Some conditions that are effective to the removal of Cd2+, Ni2+, CrO42- by adsorption process using the GFC material including pH, contact time and initial concentration of the metal ions were systematically studied. The optimized pH for removal Cd2+, Ni2+, CrO42- for GFC was 6.0, 5.0, 3.5, respectively. The contact time was 50 min. The adsorption mechanism of GFC composite material was well described by Langmuir isotherm with a maximum adsorption capacity (qmax) for Cd2+, Ni2+, CrO42- of 8.123, 30.96, 40 mg/g, respectively, and pseudo-second-order kinetic model was well fited for the adsorption mechanism, which implied that the uptake  of Cd2+, Ni2+, CrO42-  onto GFC following a chemical adsorption.

In this study, Graphene oxide (GO) was synthesized for the treatment of antibiotic residues in the aquatic environment. The characteristics of GO material were analyzed by the XRD, and SEM methods. The GO material was used for the adsorption of tetracycline hydrochloride (TCH) in an aqueous environment. The adsorption equilibration time is 30 min. The factors that affect the adsorption process were investigated including the initial TCH concentration (10-40 mg/L), the GO content (0,1-0,5 g/L), and the pH solution (1-9). The adsorption process of TCH on GO material is consistent with the Freundlich isotherm model. The TCH adsorption process of GO material is exothermic.

Ciprofloxacin imprinted polymers have garnered significant attention due to the high demand for application in the monitoring of antibiotics. This study focuses on the synthesis and selective adsorption properties of ciprofloxacin imprinted polymers. The polymers were synthesized via precipitation polymerization technique. Optimal condition was achieved using acetonitrile:water (8:2, v/v) and a molar ratio of ciprofloxacin:acid methacrylic:ethylene glycol dimethacrylate of 1:6:30. Physicochemical characterization utilizing FT-IR, TGA-DSC, SEM, and N2 adsorption isotherm confirmed the desired properties of the polymer. Adsorption properties (kinetic, pH, and isotherm) indicated selective adsorption of ciprofloxacin onto the imprinted polymer with an imprinting factor of 1.34 and adsorption capacity up to 11.6 mg g-1. These findings underscore the potential of the ciprofloxacin imprinted polymer as a stationary phase for solid-phase extraction columns.

Published: June 2024

In recent years, it has been recognized that the bridging angle in Me−eIM−Me (Me: Zn or Co and eIM : 2-ethylimidazolate) is coincident with that of the Si−O−Si angle in zeolites (145°), and therefore it can make new metal azolate frameworks (MAFs) with topologies based on tetrahedral zeolites.
Me(eIM)2 belongs to the family of MAFs, has three isomers which have the same molecular formula but different topology (ANA-MAF-5, RHO-MAF-6 and qtz-MAF-32). These materials are hydrophobic, have large capillary diameters, thermally and hydrothermally stable, so they have different physical and chemical properties, leading to different applications in practice.
This review report collects results from more than 100 research papers related to Me(eIM)2 from 2006 to present and provides some recommendations on their synthesis, characterization and application in the future.

Authors: Giannakopoulos Nikolaos
Published: June 2024

The present study aims to implement the flipped classroom teaching model in the Greek curriculum for chemistry from 8th to 12th grade students. Specifically, this involves designing and creating suitable educational material according to the flipped classroom methodology for targeted chemistry course units, which include laboratory exercises as well. The flipped classroom is a blended learning model, where students prepare by watching video lectures or other educational material at home, while homework is conducted in the classroom with the assistance of the teacher and students discussing and resolving questions. The teacher supports students exactly where they encounter difficulties, thus shifting their role from traditional lecturing to guiding, supporting, and individualizing.

Published: June 2024

OBJECTIVE: To compare the prevalence of problematic internet use (PIU) in attention deficit hyperactivity disorder (ADHD) and non-ADHD children and explore the related factors and effects of PIU in children.METHODS: A cross-sectional study was done. ADHD and non-ADHD participants aged 7-15 years old with current internet use were enrolled. A self-report questionnaire collected child and parental demographic data, internet use, and related data. An internet addiction scale was used.RESULTS: A total of 127 participants were enrolled, including 56 ADHD participants and 71 non-ADHD participants. The rate of possible PIU and PIU (possible PIU/PIU) in the ADHD group was 60.7% and 61.5% in the non-ADHD group. In the ADHD group, internet usage time ≥ 21 hours per week was a significant related factor to possible PIU/PIU (adjusted odd ratio 27.08, 95% confidence interval 2.35 – 312.04). Male was significant related factor to possible PIU/PIU in the non-ADHD group (adjusted odd ratio 4.25, 95% confidence interval 1.25 - 14.47). School level, grade, online gaming or social media exposure, and parental internet restriction were non-significant related factors in both groups. Children with possible PIU/PIU had significantly more positive depressive symptoms than the normal internet use group (p = 0.006).CONCLUSION: The results indicate a higher rate of possible PIU/PIU in both groups and a significant relation with depressive symptoms. In routine practice, we should clarify this issue and provide education to families and children with or without ADHD to prevent internet related problems.
