ABSTRACTThis research elucidated the hypoglycemic effect correlated with DNA‐protective and antioxidative activity of Lasia spinosa stem aqueous extract (LSSAE) using streptozotocin‐induced type 2 diabetic rat models. LSSAE, characterized by phytochemical screening, gas chromatography–mass spectroscopy (GC–MS), and FTIR analyses, was investigated for its DNA‐protective activity by exposing PBR322 plasmid DNA to Fenton's reagents. Long Evans rats, treated by LSSAE, were found to be improved for body weight, fasting blood glucose level, and oral glucose load. A 30‐day supplement of LSSAE significantly recovered serum biochemical markers, including hepatic (i.e., ALP, AST, ALT, and TB); renal (i.e., creatinine and uric acid); and lipid profiles (i.e., TC, TG, HDLc, LDLc, and VLDLc). An increased level of superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH), and a decreased level of malondialdehyde (MDA) were observed in LSSAE‐treated rat liver. Antioxidant enzyme activities were evaluated by mRNA expression level of antioxidant genes (CAT, SOD2, GPX1, PON1, PFK1, GAPDH, using the 2−ΔΔCT method, normalized with housekeeping gene, ß‐ACTIN) using qRT‐PCR. Additionally, histological examination confirmed the restoration of morphology, and function of pancreatic β‐cell, kidney, liver, and spleen. Results reveal that LSSAE exerts an antidiabetic effect through upregulation of antioxidant genes, DNA protection and modulation of biochemical and histological parameters.

Mitragyna speciosa Korth. Havil (MS) has a traditional use in relieving pain, managing hypertension, treating cough, and diarrhea, and as a morphine substitute in addiction recovery. Its potential in addressing Alzheimer’s disease (AD), a neurodegenerative condition with no effective treatments, is under investigation. This study aims to explore MS mechanisms in treating AD through network pharmacology, molecular docking, and in vitro studies. Using network pharmacology, we identified 19 MS components that may affect 60 AD-related targets. The compound–target network highlighted significant interactions among 60 nodes and 470 edges, with an average node degree of 15.7. The KEGG enrichment analysis revealed Alzheimer’s disease (hsa05010) as a relevant pathway. We connected 20 targets to tau and β-amyloid proteins through gene expression data from the AlzData database. Docking studies demonstrated high binding affinities of MS compounds like acetylursolic acid, beta-sitosterol, isomitraphylline, and speciophylline to AD-related proteins, such as AKT1, GSK3B, NFκB1, and BACE1. In vitro studies showed that ethanolic (EE), distilled water (DWE), and pressurized hot water (PHWE) extracts of MS-treated 100 μM H2O2-induced SH-SY5Y cells significantly reduced oxidative damage. This research underscores the multi-component, multi-target, and multi-pathway effects of MS on AD, providing insights for future research and potential clinical applications.

In mode division multiplexing (MDM) technology multi-band higher order mode (HOM) pass filters are rarely introduced. However, these filters will support the MDM technology to be universal for all available wavelength bands used in fiber optic communication systems. In this work, two TE1 mode pass filters (MF1 and MF2) have been proposed using silicon subwavelength grating (SSWG) structures embedded in the multi-mode waveguide to operate in a dual band (O-band and C-band). The MF1 with gratings of two distinct grating periods and a device length of only 23 μm shows excellent performance in terms of excess losses (EL) of 0.20 dB and 0.38 dB at the center wavelengths of the O band and C band respectively, with TE1-TE0 extinction ratios (ER) of 56.54 dB and 47.73 dB at the respective wavelengths. The TE0 mode rejections are < -25 dB in the O-band and < -45 dB in the C-band. On the other hand, the MF2 designed with gratings of uniform grating period has an ultra-compact device length of only 18 μm and shows almost similar mode rejections for TE0 mode as MF1. The ELs are 0.95 dB and 0.374 dB at the center wavelengths of O-band and C-band respectively, while the TE1-TE0 ERs are 40.60 dB and 61.36 dB at these respective wavelengths. Both of the filters have bidirectional properties. Fabrication tolerance analysis indicates that our proposed devices are tolerant within ±20 nm variations in the period, pitch, and width of the gratings.

ABSTRACTFlavonoids have been showing diversified bioactivities. Primary amoebic meningoencephalitis is a brain inflammation caused by Naegleria fowleri brain eating amoeba. In this manuscript, we selected 93 flavonoids by extensive literature survey and 83 flavonoids passed drug likeness parameter. Selected flavonoids were molecular docked against primary amoebic meningoencephalitis N. fowleri CYP51 receptor considering voriconazole as standard. Beta naphthoflavone, abyssinone I, and abyssinone III showed maximum docking scores of −10.9 kcal/mol, −10.7 kcal/mol, and −10.6 kcal/mol, respectively, whereas voriconazole showed docking scores of −7.6 kcal/mol. Molecular dynamic simulation data showed that RMSD values attained almost a static value during the simulation, and all nearest interacting amino acid residues were fluctuated within limit. Molecular Mechanics Poisson‐Boltzmann Surface Area (MMPBSA) data of beta naphthoflavone abyssinone I, abyssinone III, and voriconazole showed free binding energies of −82.755 kJ/mol, −1924.193 kJ/mol, −1890.335 kJ/mol, and −540.141 kJ/mol, respectively. Frontier molecular orbital (FMO) analysis showed that abyssinone III was the chemically reactive molecule and beta naphthoflavone showed maximum electrophilicity. Molecular electrostatic potential (MEP) analysis portrayed possible nucleophilic‐electrophilic attack areas of the structures. PCA and free energy landscape (FEL) analysis data confirmed the stable conformations between flavonoids and receptor. Abyssinone I and III showed nontoxic behavior. These data confirmed that if we repurpose these flavonoids against primary amoebic meningoencephalitis, it will be beneficial for mankind.

 |  Abstract
Climate change-induced hazards and environmental change pose great threats and vulnerabilities to the livelihoods and food security of forest-dependent coastal people in Bangladesh. Moreover, the recent surge of COVID-19 has aggravated this vulnerability manifold. This paper is an attempt to examine the aspects of food security and subsistence systems of coastal people in dual hazards. It also explores the gender roles and responses of coastal people in food security and subsistence systems in climatic hazards during the period of COVID-19. This project employed participant observation, in-depth interviews (N=55), and Focus Group Discussions (FGDs)(N=7) for collecting data. The findings of the research demonstrate that climate-induced hazards severely reduce the resources of the forest and river and threaten the food security of coastal people. Many of the coastal people are forced to change their occupations, diversify their livelihoods, or migrate to other places for subsistence. Moreover, the recent outbreak of COVID-19 restricts them in-house and stops their income-generating activities. In addition, forest departments do not allow them to enter forests to collect forest resources during and after the hazards, which severely affects their food security. In coastal areas, women play a great role in food security and subsistence systems, but dual hazards limit their working opportunities by restricting agricultural inputs, and technological support, disrupting the environment, closing markets, breaking supply chains, and so on. However, coastal people try to overcome these challenges by applying their local strategies. This paper helps policymakers and the government to gain insight into the real situation of coastal people during and after the hazards, which can influence policymakers to formulate effective policies for ensuring food security and creating alternative subsistence systems for coastal people in adversity.

 |  Abstract
Climate change has gained global recognition as one of the most urgent challenges in recent decades. Many indigenous people attempt to overcome great challenges in their lives by adhering to their cultural customs and traditional knowledge. This is especially true for those who live in isolated, hilly places and are dependent on natural resources. The aim of the paper is to critically investigate the cultural facets of indigenous people's adaptation to and resilience to climate change in the Chittagong Hill Tracts (CHT), namely in the Rangamati Sadar sub-districts of the Rangamati districts,Bangladesh. This paper also examines how cultural components in indigenous community are changing and influencing the adaptation process in adverse situations. This study used a critical ethnography technique in conjunction with participant observation, in-depth interviews (N=55), and focus group discussions (N=5, 45 participants) during a one-year period (October 2019 to October 2020). According to the study's findings, climate change-related risks have significant adverse effects on indigenous people. However, they develop their strategies to adjust to the adverse environment, like building different kinds of houses, changing cultural customs, relying less on natural resources, and adhering to their indigenous knowledge. They also strengthen their prayers and ceremonial practices, which reinforce their communal ties and allow them to become more resilient against challenges in their community. The popular belief that Indigenous people are stupid, poor, and helpless while they wait for outside help is challenged by this study. It also refutes the discourse that indigenous strategies and knowledge are not undervalued and can be an effective instrument for the adaptation process and combating hazards.

This investigation Extensively explored the synthesis and potential therapeutic applications of derivatives derived from methyl α-d-mannopyranoside. It encompasses a wide range of evaluations, including antimicrobial assessments, molecular docking, dynamic simulations, and ADMET analysis. Spectroscopic methods (FTIR, 1H NMR, 13C NMR, mass) were used to confirm the structures of the synthesized mannopyranoside derivatives. This study assessed the antibacterial activity of the strains against a range of both gram-positive and gram-negative bacteria and revealed significant inhibitory effects. In addition, the mannopyranoside derivatives exhibited significant antifungal activity. Additionally, we studied how to improve the thermal, frontier molecular orbital (FMO), and molecular electrostatic potential (MEP) properties of mannopyranoside and its acylated analogs by using density functional theory (DFT). Molecular docking studies provided further evidence of the advantageous antibacterial effects of the mannopyranoside derivatives 3, 6, and 7 against the penicillin-binding protein PBP2a (1VQQ) from the methicillin-resistant binding protein Staphylococcus aureus. The docking results were confirmed via molecular dynamics (MD) simulations, which provided a dynamic view of protein stability. The conformational stability increased in the simulations, and the values of the solvent-accessible surface area (SASA) and radius of gyration (Rg) were found to be consistent and stable. Reduced root mean square fluctuations (RMSFs), facilitated by strong hydrogen bonding interactions, characterize ligand–protein interactions. The toxicological and pharmacokinetic profiles of the molecule were assessed using ADMET analysis. The results showed that the molecule had favorable drug-like features, making it a strong candidate for further development. Overall, these findings indicate that 3-nitobenzoylated mannopyranoside derivatives exhibit considerable potential as therapeutic agents for treating microbial infections.

Carbohydrates, among the most abundant and widespread biomolecules in nature, play indispensable roles in diverse biological functions and represent a treasure trove of untapped potential for pharmaceutical applications. From this perspective, the present study was designed to explore and evaluate the synthesis and spectral characterization of methyl α-D-glucopyranoside derivatives 2-6 with different aliphatic groups through comprehensive in vitro antimicrobial screening, physicochemical analysis, molecular docking and molecular dynamics analysis, and pharmacokinetic prediction. The unimolar one-step propionylation of methyl α-D-glucopyranoside under controlled conditions furnished 6-O-propionyl derivative 2 and the development of glucoopyranoside-based potential antimicrobial derivatives, which were further converted into four newer 2,3,4-tri-O-glucopyranoside derivatives (3-6) in reasonably good yields. The chemical structures of the newly synthesized analogs were ascertained by analyzing their physicochemical, elemental, FTIR, and NMR spectroscopic data. In vitro antimicrobial tests against five bacteria and two fungi indicated the promising antibacterial functionality of these synthesized analogs compared with their antifungal activity. Structure-activity relationship (SAR) analysis indicated that adding lauroyl> stearoyl > palmitoyl groups to the ribose moiety increased the potency against bacterial and fungal strains. In support of this observation, molecular docking experiments were performed on the 3TI6 H1N1 receptor and the 6VMZ H5N1 receptor. Molecular interactions with solvents were investigated in terms of FMO, HOMO-LUMO, and MEP properties. In addition, a 100 ns molecular dynamics simulation process was performed to monitor the behavior of the complex structure formed by the receptor 6VMZ under in silico physiological conditions to examine its stability over time, which revealed a stable conformation and binding pattern in a stimulating environment of methyl α-D-glucopyranoside derivatives. Pharmacokinetic predictions were investigated to evaluate their absorption, distribution, metabolism and toxic properties, and the combination of pharmacokinetic and drug-likeness predictions has shown promising results in silico.

This study involves a computational analysis of new D-π-A dyes obtained from triphenylamine (TPA), which contain various azo-dye components. The structural, molecular, electrical, and optical properties of these dyes were computed using Density Functional Theory (DFT) and Time-Dependent DFT, utilizing the B3LYP/6-31G model. Our research specifically aimed to investigate the effects of incorporating different azo dye constituents in the para position of two phenyl groups of TPA. The results indicate that these alterations lead to notably broadened and red-shifted absorption spectra, as well as improved optoelectronic properties that are subject to additional tuning through the manipulation of the π-spacer. The excitation energies and HOMO-LUMO energy levels that have been estimated indicate the presence of effective electron injection and dye regeneration mechanisms. The results concerning the nonlinear optical (NLO) properties suggest that these dyes are likely to demonstrate superior performance in NLO applications. The factors encompassed in this study consist of light-harvesting efficiency (LHE), open-circuit photovoltage (VOC), electron injection driving force (ΔGinj), dye regeneration driving force (ΔGreg), excited state lifetime (τ) and reorganization energy (λtotal), which has a strong correlation with the electrical current density in a short-circuit (JSC) and DSSC's overall effectiveness. This scientific attempt contributes to the systematic advancement of efficient dyes, demonstrating the possibility for enhanced efficiency in DSSCs. Further validation of computational forecasts and advancement of renewable energy technology necessitate future experimental synthesis and testing.

Urban areas face high particulate matter (PM10) levels, increasing the risk of respiratory and cardiovascular diseases. Green spaces can significantly reduce PM10 concentration, as shown at various scales, from boroughs to whole cities. However, long-term monitoring is needed to understand the specific mechanisms and cumulative impact of green spaces on air quality to changing pollution levels. We investigated the influence of neighbourhood green space percentage, climatic variables, and population density on PM10 deposition during the vegetation period across eight cities in contrasting climate zones over 20 years (2000-2020). We used a correlation matrix, generalized additive model, one-way ANOVA, and Tukey HSD test to analyze the impact of these factors on PM10 deposition rates, assess the role of green space percentage in reducing it, and identify significant differences in PM10 parameters at different proximities to emission sources. Cities with higher population density in warmer, drier climates had higher PM levels, since land surface temperature and wind pressure positively correlated with PM10 deposition, while relative humidity showed a negative correlation. The study found significantly higher PM10 concentrations in industrial areas (36.25 μg/m³) than in roadside areas (25.73 μg/m³) and parks (20.17 μg/m³) (p < 0.01). This highlights the need for targeted interventions in different zones. The study found a complex relationship between green space percentage and PM10 deposition rate onto plant surfaces. Our model suggests that at least 27% of green spaces as land cover can significantly reduce the particulate matter flux, although the minimum threshold can vary depending on the specific urban contexts. The study focused on the proportionate cover of green spaces; still, further investigation including quantitative aspects of urban surface forms, and traffic emissions can comprehend the climatic context and determine the optimal extent of green space required for strategic planning toward future urban sustainability initiatives.

Indian Historical Review 2024 citations by CoLab: 0  |  Abstract
In Burmese historiography, the issue of periodisation has not been given much attention. Burma’s pre-colonial history of dynastic and ruler changes occurred within a static framework with little to no institutional or social change. Before the British conquest, the political history of Burma can be summed up as an endless struggle between the Burmese people and their neighbours, as well as between at least four different indigenous groups: Shans, Arakanese, Mons or Talaings. Numerous political organisations and migrations occurred during the pre-colonial era. The Pyu city-states, the Pagan Empire, the Toungoo Dynasty and the Konbaung Dynasty were the four pre-colonial systems covered in this article. Mercantilism, Buddhism, commerce with Asian countries, and cultural and political concepts had a significant impact on Pyu culture, which may have long shaped later Burmese governmental structures and society. In the Pagan Kingdom, farming, irrigation, culture and design attained a high degree of development and were formed by the ancestors of the trendy Burmese. The Kanbwang Dynasty came to power in the eighteenth century and established central authority nearby. Early in the nineteenth century, colonial powers seized control of Burma. The main objectives of this article are the political and social landscape of pre-colonial Burma and how it impacted colonialism. The article also makes connections between periods of Burma’s colonial history and early modern history.

Extracellular vesicles (EVs) play important roles in intercellular communication in various biological events. In particular, EVs released from cancer cells have attracted special attention. Although it has been reported that cancer-associated glycosphingolipids play important roles in the enhancement of malignant properties of cancer cells, the presence, behavior, and roles of glycosphingolipids in EVs have not been elucidated. Recently, we reported crucial roles of EVs expressing gangliosides, GD2, and/or GD3 in the enhancement of cancer properties in malignant melanomas and gliomas. However, how EVs containing cancer-associated glycosphingolipids play their roles has not been reported to date. Here, we studied spatio-temporal mechanisms for GD3/GD2-containing EVs released from gliomas in the actions toward target cells. Proteome analyses of EVs with/without GD3/GD2 revealed an equally high concentration of integrin isoforms in both GD3/GD2+ and GD3/GD2- EVs. PKH26-labeled EVs attached, invaded, and distributed to/in the target cells within 1 h. GD3/GD2 formed molecular complexes with integrins on EVs as elucidated by immunoprecipitation/immunoblotting and immunocytostaining. The addition of antibodies reactive with GD3, GD2, or integrins resulted in the suppression of the enhancing effects of EVs in the cell adhesion assay. The addition of GD3/GD2 + EVs to GD3/GD2- cells clearly increased the phosphorylation levels of the PDGF receptor, FAK, and Erk1/2 in immunoblotting, suggesting GD3/GD2+ EVs activate the signaling pathway in the target cells within 15 min after addition. Anti-ganglioside antibodies clearly blocked signaling with EVs. In conclusion, EVs released from GD3/GD2-expressing glioma cells enhance cancer phenotypes and malignant signals via the cluster formation of integrins and GD3/GD2 on EVs, leading to the regulation of the cancer microenvironment.

Background: In the realm of system biology, it is a challenging endeavor to infer a gene regulatory network from time-series gene expression data. Numerous Boolean network inference techniques have emerged for reconstructing a gene regulatory network from a time-series gene expression dataset. However, most of these techniques pose scalability concerns given their capability to consider only two to three regulatory genes over a specific target gene. Methods: To overcome this limitation, a novel inference method, LBF-MI, has been proposed in this research. This two-phase method utilizes limited Boolean functions and multivariate mutual information to reconstruct a Boolean gene regulatory network from time-series gene expression data. Initially, Boolean functions are applied to determine the optimum solutions. In case of failure, multivariate mutual information is applied to obtain the optimum solutions. Results: This research conducted a performance-comparison experiment between LBF-MI and three other methods: mutual information-based Boolean network inference, context likelihood relatedness, and relevance network. When examined on artificial as well as real-time-series gene expression data, the outcomes exhibited that the proposed LBF-MI method outperformed mutual information-based Boolean network inference, context likelihood relatedness, and relevance network on artificial datasets, and two real Escherichia coli datasets (E. coli gene regulatory network, and SOS response of E. coli regulatory network). Conclusions: LBF-MI’s superior performance in gene regulatory network inference enables researchers to uncover the regulatory mechanisms and cellular behaviors of various organisms.

Potentially toxic elements (PTEs) and microplastics (MPs) in the atmosphere raise widespread apprehension due to their association with the ecosystem and public health. The accumulation of airborne MPs and PTEs was analyzed in Polyalthia longifolia leaves, and the Pollution Index (PI) was calculated along an industrial, residential, and rural gradient in Bangladesh. Only polyethylene terephthalate (PET) was found in the highest concentration in industrial areas compared to other areas. In leaves, a significantly higher Cd, Pb, and Zn concentration was found in industrial regions compared to residential and rural areas. For Cd, the PI was observed to be higher than 1 in rural areas, indicating a moderate level of pollution; it was higher than 3 in residential areas, showing considerable pollution; and it was found to be more than 6 in industrial areas. The higher concentration of both MPs and PTEs with increasing urbanization reflects the influence of anthropogenic activities. The findings of the study demonstrate the fascinating potential of P. longifolia tree leaves as a promising bioindicator for air quality biomonitoring.
