This review delves into the intricate relationship between gut microbiota, autophagy, and the development of IBD. The gut microbiota, a diverse community of microorganisms, plays a vital role in maintaining gut health, while imbalances in this microbial community, known as dysbiosis, are linked to IBD. Autophagy, a process by which cells recycle their components, is essential for gut homeostasis and the regulation of immune responses. When autophagy is impaired and dysbiosis occurs, they individually contribute to IBD, with their combined impact intensifying inflammation. The interconnectedness of gut microbiota, autophagy, and the host’s immune system is central to the onset of IBD. The review also examines how diet influences gut microbiota and its subsequent effects on IBD. It highlights the therapeutic potential of targeting the microbiota and modulating autophagic pathways as treatment strategies for IBD. Understanding these interactions could lead to personalized therapies within the rapidly advancing fields of microbiome research and immunology.

In this review, we focus on the efficacy of celastrol in mitigating memory impairment (MI) in both in vivo and in vitro models. Scopus, PubMed and Web of Science databases were utilised to locate pertinent literatures that explore the effects of celastrol in the brain, including its pharmacokinetics, bioavailability, behavioral effects and some of the putative mechanisms of action on memory in many MI models. To date, preclinical studies strongly suggest that celastrol is highly effective in enhancing the cognitive performance of MI animal models, particularly in the memory domain, including spatial, recognition, retention and reference memories, via reduction in oxidative stress and attenuation of neuro-inflammation, among others. This review also emphasised the challenges and potential associated enhancement of medication delivery for MI treatment. Additionally, the potential structural alterations and derivatives of celastrol in enhancing its physicochemical and drug-likeness qualities are examined. The current review demonstrated that celastrol can improve cognitive performance and mitigate MI in several preclinical investigations, highlighting its potential as a natural lead molecule for the design and development of a novel neuroprotective medication.Graphical Abstract: Keywords: celastrol, memory impairment, neuroprotection, drug discovery, natural products

It was previously used as an anticancer drug but has been discontinued because of its toxic effects. However, according to the most recent studies, the toxicity of streptonigrin and its structurally modified derivatives has been reduced while maintaining their potential pharmacological action at lower concentrations. To date, many investigations have been conducted on this molecule and its derivatives to determine the most effective molecule with low toxicity to enable new drug discovery. Therefore, the main objective of this study is to provide a comprehensive review and to discuss the prospects for streptonigrin and its derived compounds, which may boost the molecule as a highly interesting target molecule for new drug design, development and therapy. To complete this review, relevant literature was collected from several scientific databases, including Google Scholar, PubMed, Scopus and ScienceDirect. Following a complete screening, the obtained information is summarized in the present review to provide a good reference and accelerate the development and utilization of streptonigrin and its derivatives as pharmaceuticals.Graphical Abstract: Keywords: streptonigrin, chemistry, biosynthesis, pharmacology, anticancer, antibacterial

Indian adults’ incidence of mild and moderate periodontal conditions was nearly 25%, while about 19% of adults experience severe periodontitis.Objective: The aim of this study was to analyse epidemiological factors of periodontal disease among a south Indian population based on the role of sociodemographic factors, habitual factors and set of oral health knowledge, attitude, and behaviour measures.Methods: A sample of 288 participants above 18 years of age residing in Tamil Nadu, India took part in this cross-sectional study. Based on WHO criteria, periodontal disease was measured in our study. Age, ethnicity, smoking, education, and oral health behavior were found to be the covariates. Ordinal logistic regression analysis using R version 3.6.1 was utilized to study the various factors that influence periodontal disease among south Indian adults.Results: Various demographic factors such as age between 25 and 34 years (AOR = 2.25; 95% CI 1.14– 4.55), 35– 44 years (AOR = 1.80; 95% CI 0.89– 3.64), ≥ 45 years old (AOR = 2.89; 95% CI 1.41– 6.01), ethnicity (AOR = 2.71; 95% CI 1.25– 5.81), smoking (AOR = 0.38; 95% CI 0.16– 0.65), primary level education (AOR = 0.07; 95% CI 0.01– 0.50) high school level education (AOR = 0.06; 95% CI 0.01– 0.27), university level education (AOR = 0.08; 95% CI 0.01– 0.36) and an individual’s oral health behavior (AOR = 0.59; 95% CI 0.32– 1.08) were found to be related with periodontal disease among the south Indian population. The maximum log likelihood residual deviance value was 645.94 in the final model.Conclusion: Based on our epidemiological findings, sociodemographic, habitual factors and oral health behavior play a vital role in an individual’s periodontal status among south Indian adults. An epidemiological model derived from the factors from our study will help to bring better understanding of the disease and to implement various preventive strategies to eliminate the causative factors.Keywords: periodontal disease, epidemiology, modelling, socio-demography, habits

During normal aging, the heart undergoes functional, morphological and cellular changes. Although aging per se does not lead to the expression of heart failure, it is likely that age-associated changes lower the threshold for the manifestation of signs and symptoms of heart failure. In patients, the susceptibility, age of onset and pace of progression of heart failure are highly variable. The presence of conventional risk factors cannot completely explain this variability. Accumulation of DNA damage and telomere attrition results in an increase in cellular senescence and apoptosis, resulting in a decrease in the number and function of cells, contributing to the overall tissue and organ dysfunction. Biological aging, characterized by reduced telomere length, provides an explanation for the highly interindividual variable threshold to express the clinical syndrome of heart failure at some stage during life. In this review, we will elaborate on the current knowledge of aging of the heart, telomere biology and its potential role in the development of heart failure. [ABSTRACT FROM AUTHOR]

Introduction: the physiological & Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) was derived from a heterogeneous general population and has been used successfully as an audit tool to provide risk-adjusted operative mortality rate. The aim of this study was to investigate whether risk-adjusted scoring systems can accurately predict outcomes of colorectal operations done by colorectal and non-colorectal surgeons. Method: the study was conducted prospectively on 899 consecutive patients who underwent major elective and emergency colorectal procedures over three years between 2002 and 2004 at University Hospital Coventry and Warwickshire. The outcome parameter was defined as 30-day mortality. The observed mortality was then compared to POSSUM-predicted mortality. Hosmer-Lemeshow and Fisher's Exact test were used to assess statistical significance in outcome between non- and coloproctologists. Results: CR-POSSUM was the most accurate predictive model for outcomes of major colorectal operations between surgeons. The overall mortality rate amongst coloproctologists was 7% (5% elective & 13% emergency), whereas the overall mortality was 17% (3% elective & 21% emergency) in non-coloproctologists. Conclusion: CR-POSSUM was the better prediction model than POSSUM. Coloproctologists delivered a significantly lower overall mortality, but not in the emergency setting. However, given the few number of elective colorectal resections performed by non-coloproctologists, more cases are required to permit meaningful comparison for the outcomes of major colorectal operations among different surgeons.

Background: Postoperative morbidity and mortality from colorectal cancer varies widely across hospitals in the UK. We aimed to assess whether a newly developed score from the Association of Coloproctology of Great Britain and Ireland (ACPGBI) could predict mortality from colorectal cancer surgery as accurately as the Physiology and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM), Portsmouth POSSUM (P-POSSUM), or the ColoRectal POSSUM (CR-POSSUM). Methods: We analysed prospectively 618 patients with histologically confirmed colorectal cancer who had surgery to remove primary tumours done by colorectal surgeons or non-colorectal surgeons in a 3-year period. We compared observed mortality with those predicted by the ACPGBI, POSSUM, P-POSSUM, and CR-POSSUM scoring systems using the Hosmer-Lemeshow test and Receiver Operating Characteristic (ROC) curve analysis. Findings: Between April 1, 2002, and May 31, 2005, 618 consecutive patients with colorectal cancer had surgery to remove primary tumours. Overall observed 30-day mortality over the 3 years was 10.2% (95% CI 8.0-12.9). Overall predicted mortality (mean score) by use of POSSUM was 12.7% (11.7-13.7), by use of P-POSSUM was 4.4% (3.4-5.4), by use of CR-POSSUM was 9.6% (8.6-10.6), and by use of ACPGBI score was 8.1% (7.3-8.8). Interpretation: POSSUM overpredicted mortality, whereas P-POSSUM underpredicted mortality from colorectal-cancer surgery. CR-POSSUM was a more-accurate predictor of mortality in most analyses than was POSSUM and P-POSSUM. Although CR-POSSUM gave the closest prediction of overall mortality, analyses of subgroups of patients showed that ACPGBI score predicted overall mortality most accurately. [ABSTRACT FROM AUTHOR]

We present the chemical synthesis of polyethyleneimine-conjugated silver sulfide nanoparticles (PEI/AS) utilizing an economical solvothermal synthesis method, aimed at developing effective alternative antibacterial agents. The antibacterial efficacy of the synthesized materials, both with and without the application of near-infrared (NIR) laser irradiation, was evaluated in vitro against two distinct clinically relevant multi-drug-resistant (MDR) uropathogenic strains: Escherichia coli and methicillin-resistant Staphylococcus aureus . The bactericidal effects induced by NIR light indicate that the PEI/AS nanoparticles possess an efficiency that is five times greater than that of Ag 2 S alone. A suggested antibacterial mechanism posits that the wrapping of PEI increases electrostatic interactions, thereby facilitating the attachment of Ag 2 S nanoparticles to the bacterial surface. This process leads to the disruption of the outer membrane through the generation of localized heat and an increased concentration of reactive oxygen species (ROS), including superoxide anions (·O 2 - ) and hydroxyl radicals (·OH). In addition, the mechanism involves the regulated release of Ag + ions when exposed to NIR light irradiation. The combined action led to an over 95.79% elimination of bacteria at a concentration as low as 50 μg mL -1 , which can be primarily ascribed to the regulated photothermal effect induced by 808 nm near-infrared light irradiation, demonstrating exceptional photothermal conversion efficiency. These results paves a way for manufacturing innovation in future., Supplementary Information: The online version contains supplementary material available at 10.1007/s13205-024-04168-3., Competing Interests: Conflict of interestThe author declares no conflict of interest., (© King Abdulaziz City for Science and Technology 2024.

The wild edible plants offer a valuable resource for food and human nutrition. The current study aimed to analyze the proximate composition and ethno-medicinal profiles of twenty selected wild edible plants from the Malakand District, Pakistan. The proximate composition (moisture, ash, crude protein, crude fat, and dietary fiber) was analyzed following Association of Official Agricultural Chemists (AOAC) protocols. Ethno-medicinal profiles were obtained through semi-structured interviews with local informants. Mineral elements were analyzed using Energy Dispersive X-ray Fluorescence (EDX) Spectroscopy. The normalized variation matrix and centered log ratio (CLR) biplot were used to assess linear associations between nutritional components. The results revealed significant variations in the nutritional components and mineral contents among the studied plant species. Higher crude carbohydrates (64.48%) were scrutinized in Ziziphus jujuba, followed by proteins (19.90%) in leaves of Solanum nigrum, fiber (19.50%) in Caralluma tuberculata and fats (6.12%) in Mentha spicata. A maximum energy value of 332.34 Kcal/100g was calculated for leaves of Solanum nigrum. The concentrations of carbon (C) in Mentha longifolia were (60.20%), followed by oxygen (46.06%) in Ziziphus jujuba, potassium (10.80%) in Rumex dentatusand nitrogen (7.98%) in Nasturtium officinale. The centered log ratio biplot confirms strong relationships between moisture, energy, carbohydrates, fibers, and ash content, while protein and fat concentrations exhibit a separate pattern. The findings provide valuable insights into the compositional data analysis of edible plant species, suggesting interdependencies among carbohydrate, energy, moisture content, and fibers. Additionally, the results of our current study showed that all of these selected wild edible plants have the potential to provide humans with important macronutrients and elements.

The field of green synthesis, namely using plant extracts for the production of metal nanoparticles, is rapidly gaining traction. Therefore, this study investigated the process of producing zinc oxide nanoparticles (ZnO NPs) using a water-based extract derived from the stem bark of Calophyllum teysmannii. Notably, this is the first documented utilization of this particular plant source. The presence of a distinct Ultraviolet-Visible (UV-Vis) absorption peak at 372 nm provided evidence for the creation of ZnO nanoparticles. The X-ray Diffractometer (XRD) and Field Emission Scanning Electron Microscopy (FESEM) investigations indicated that the nanoparticles exhibited sizes ranging from 31.5 to 59.9 nm and had spherical morphologies. Energy Dispersive X-ray Diffractometer (EDX) analysis verified the elemental composition of the ZnO nanoparticles, whereas the Fourier Transform Infrared (FTIR) spectra showed clear peaks, demonstrating their production. The FTIR examination of the C. teysmannii extract revealed peaks at around 3370 cm - 1 , indicating the presence of phenolic compounds. These chemicals are likely responsible for the reduction and stabilization of the ZnO NPs. The high-resolution X-ray Photoelectron Spectroscopy (XPS) spectra clearly revealed separate peaks corresponding to Zn 2p and O 1s, providing confirmation of the chemical states and bonding contexts. The Raman Spectroscopy analysis revealed a distinct peak at around 425 cm⁻¹, confirming the presence of the wurtzite structure. The harmful effects of ZnO nanoparticles on HCC2998 (a kind of human colon cancer) and Vero (a type of monkey kidney epithelial) cells were evaluated using 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT), dichlorodihydrofluorescein diacetate (DCFH-DA), and boron-Dipyrromethene (BODIPY) assays. The cancer cells underwent cell death due to oxidative stress in a dose-dependent manner, as confirmed by microscopic and flow cytometry investigations., Competing Interests: Declarations.

Tetracarpidium conophorum nuts are nutrient-dense Nigerian snacks associated with weight regulation. This study explores the nuts' impact on adipose tissue gene expression associated with low-grade inflammation. Ethanol whole extract (EWE), ethyl-acetate fraction (EAF) and the resulting residue (RES) were orally administered once daily to MSG-induced obese rats for 6 weeks (n = 6). Afterward, the RNA synthesis of inflammation-associated genes was measured, and GC-MS ligands in the extract and fractions were docked against their protein products in silico. The study found that in obese animals, PPAR-γ and Adiponectin expressions were down-regulated, while TNF-α was up-regulated, indicating an increased low-grade inflammatory process in adipose tissue. After 6-week oral treatments with EWE, EAF and RES, PPAR-γ and Adiponectin expressions increased significantly, while TNF-α expression decreased, suggesting the modulation of obesity-induced inflammation in adipose tissue. The in silico molecular docking analysis identified four lead compounds likely responsible for the observed effect, namely 6-Isopropenyl-4,8a-dimethyl-4a,5,67,8,8a-hexahydro-1H-naphthalen-2-one, 9,12,15-Octadecatrienoic methyl ester (Z,Z,Z), 9,12,15-Octadecatrienoic acid and Hexanedioic acid, bis(2-ethylhexyl). Of these compounds, 6-Isopropenyl-4,8a-dimethyl-4a,5,67,8,8a-hexahydro-1H-naphthalen-2-one demonstrated the strongest affinity to the binding cavities of PPARγ (-7.3 kcal/mol), Leptin (-5.2 kcal/mol), Adiponectin (-7.1 kcal/mol) and TNF-α (-6.3 kcal/mol) and was better than the standard drug, Orlistat (-6.7, -4.4, -6.8 and - 4.5 kcal/mol, respectively). The study reveals that T. conophorum nuts possess bioactive compounds/drug candidates that can exert positive modulation, at the molecular level, the low-grade inflammatory process associated with obesity, which normally facilitates the outset of complications., (© 2024 The Author(s).

Depression represents a significant global public health challenge, and marital status has been recognized as a potential risk factor. However, previous investigations of this association have primarily focused on Western samples with substantial heterogeneity. Our study aimed to examine the association between marital status and depressive symptoms across countries with diverse cultural backgrounds using a large-scale, two-stage, cross-country analysis. We used nationally representative, de-identified individual-level data from seven countries, including the USA, the UK, Mexico, Ireland, Korea, China and Indonesia (106,556 cross-sectional and 20,865 longitudinal participants), representing approximately 541 million adults. The follow-up duration ranged from 4 to 18 years. Our analysis revealed that unmarried individuals had a higher risk of depressive symptoms than their married counterparts across all countries (pooled odds ratio, 1.86; 95% confidence interval (CI), 1.61-2.14). However, the magnitude of this risk was influenced by country, sex and education level, with greater risk in Western versus Eastern countries (β = 0.36; 95% CI, 0.16-0.56; P < 0.001), among males versus females (β = 0.25; 95% CI, 0.003-0.47; P = 0.047) and among those with higher versus lower educational attainment (β 2  = 0.34; 95% CI, 0.11-0.56; P = 0.003). Furthermore, alcohol drinking causally mediated increased later depressive symptom risk among widowed, divorced/separated and single Chinese, Korean and Mexican participants (all P < 0.001). Similarly, smoking was as identified as a causal mediator among single individuals in China and Mexico, and the results remained unchanged in the bootstrap resampling validation and the sensitivity analyses. Our cross-country analysis suggests that unmarried individuals may be at greater risk of depression, and any efforts to mitigate this risk should consider the roles of cultural context, sex, educational attainment and substance use., Competing Interests: Competing interests: The authors declare no competing interests., (© 2024.

Cystic fibrosis is an autosomal recessive condition caused by mutations in the CFTR gene, which encodes the CFTR protein. Currently, CF is a life-limiting illness that has a limited cure. The present study aimed to identify top leads against CFTR protein with F508del in comparison with Lumacaftor. In this study, a homology model of the NBD domain of CFTR protein was developed using the available NBD domain crystal structure. The protein model was refined through apo dynamics. Energy-optimized pharmacophore mapping was carried out to identify essential features for CFTR, resulting in a model with a hydrogen-bond donor, two hydrogen-bond acceptors, and three aromatic ring sites. A screening of a compound from the NPASS database using these DAARRR six-point-pharmacophore features led to the identification of potential ligands that could act against CFTR protein. Further studies such as ADME/T, molecular dynamics, MM&#95;GBSA, and DFT were performed to identify the top-hit compound from the NPASS database. The compound Anguibactin (NPC41982) has been identified as a top lead that exhibits higher binding affinity and stability than the reference compound Lumacaftor, suggesting their potential to bind to the active site of the CFTR protein. These compounds could serve as starting points for the development of drug-like molecules for treating cystic fibrosis., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this article., (Copyright © 2024 Elsevier Ltd.

The Prunus armeniaca L. (bitter apricot) is an apricot fruit tree categorized on the basis of the bitter taste of its seed kernel. In this study, the functional, medicinal, and therapeutic potential of bitter apricot seed kernel oil (BASKO) was evaluated. The qualitative screening of BASKO was performed using standard methodologies. The chemical profile of the oil was analyzed with the help of Fourier transform infrared (FTIR) and gas chromatography and mass spectrometry (GC-MS). Results revealed the presence of different phytochemical constituents comprising steroids, flavonoids, terpenoids, alkaloids, and cardiac glycosides. The antioxidant activity of the oil was determined by a 2,2,diphenyl-1picrylhydrazyl (DPPH) radical inhibition essay. Total phenolic and flavonoid contents were 10.6 ± 1.32 mg GAE/g and 4.75 ± 0.11 mg QE/g, respectively. DPPH inhibition of 89.5% was achieved at 1000  μ g/mL of BASKO, with IC 50 = 90.44  μ g/mL (83.47-96.67  μ g/mL with 95% CI). The antimicrobial potential of the BASKO revealed the inhibition of Escherichia coli (20.3 ± 2.08 mm), Salmonella typhi (19.3 ± 2.51 mm), Klebsiella pneumoniae (16.6 ± 1.52 mm), Pseudomonas aeruginosa (17 ± 2 mm), and Staphylococcus aureus (25 ± 1.01 mm). The minimum inhibitory concentration (MIC) value was 250  μ L/mL for K. pneumoniae , S. typhi , P. aeruginosa , and S. aureus , whereas 62.5  μ L/mL for E. coli . Moreover, BASKO showed antifungal potential against Trichophyton tonsurans (77.3 ± 2.08%), Epidermophyton floccosum (69.6 ± 3.51%), Aspergillus niger (74.3 ± 2.56%), Aspergillus flavus (90 ± 3%), and Mucor mucedo (78.3 ± 2.51%). Antileishmanial activity of oil was evaluated against Leishmania major by MTT assay, and an IC 50 value of 89.75  μ g/mL was observed. The study revealed that BASKO is a good source of biologically active compounds to be used as functional, therapeutical, and antimicrobial agents in food and pharmaceutical products., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Zeenat Hamid et al.)

Cognitive disorders and dementia largely influence individual independence and orientation. Based on the Alzheimer's Disease International (ADI) estimation, approximately 75% of individuals with dementia are undiagnosed. In fact, in some low- and middle-income countries, the percentage is as high as 90%. In this systematic review, which is based on PRISMA guidelines, we aim to identify the mechanism of action of proanthocyanidin. Finding a natural product alternative as a potential nootropic can help increase the number of armamentariums against dementia and other cognitive impairments. In this preclinical research, we determined the effect of proanthocyanidins on Alzheimer's disease (AD) by searching electronic bibliographic databases like Scopus, Proquest, ScienceDirect, PubMed, and Google. There was no imposed time limit. However, the search was limited to only English articles. The review protocol is registered on PROSPERO as CRD42022356301. A population, intervention, control, and outcomes (PICO) technique was utilized for report inclusion, and all reports were assessed for risk of bias by using the SYRCLE's RoB tool. The article's bibliographic information, induction model, type of proanthocyanidins, animal strain/weight/age, and outcome measurements were acquired from ten papers and are reported here. Further analysis was validated and determined for the review. The included studies met the review's inclusion criteria and suggested that proanthocyanidins have a neurocognitive effect against AD. Additionally, the effectiveness of proanthocyanidins in reducing oxidative stress, acetylcholinesterase activity, amyloid beta, its efficacy in alleviating superoxide dismutase, cognitive properties, and in facilitating cholinergic transmission in various models of AD has been collectively observed in ten studies.

The development of a new Neodymium/Dysprosium metal-organic framework, referred to as Nd/Dy-BTC MOF, based on benzene-1,2,4-tricarboxylic acid, has been achieved through an in situ growth process on 2D transition metal carbides (MXene) surfaces. This synthesis was conducted via a solvothermal method utilizing a solvent mixture of water, ethanol, and dimethylformamide. The primary objective of this research is to investigate the framework's efficacy as a photocatalyst for the degradation of anionic dye, as well as its potential for sensing certain explosives. The Nd/Dy-MOF@MXene has been characterized by various analysis techniques. The prepared Nd/Dy-MOF@MXene was utilized as catalyst in selective degradation of methyl orange dye. The study examined the influence of pH and catalyst concentration, revealing that the catalyst achieves peak efficiency of 93.55% when exposed to sunlight in an acidic medium. The reusability of the catalyst shows the highest efficient photocatalyst after four cycles of reusability. The detection of explosives, specifically 2,4,6-trinitrophenol, through photoluminescence techniques has been conducted, utilizing the Stern-Volmer equation to evaluate the quenching efficiency. The findings indicated remarkable efficiency and selectivity of Nd/Dy-MOF@MXene for 2,4,6-trinitrophenol, achieving a quenching efficiency of 91%. Furthermore, the reusability tests demonstrated that Nd/Dy-MOF@MXene exhibits outstanding recyclability, maintaining performance over five cycles. The antibacterial activity of Nd/Dy-MOF@MXene was investigated against Gram-positive and Gram-negative strains due to indication of medicine properties of Nd/Dy-MOF@MXene. These results paves a way for manufacturing innnovation in near future., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

By employing a synergistic blend of experimental and theoretical methodologies, we investigated the corrosion inhibition efficacy of a synthesized pyrazole derivative (BM-01) in a solution of hydrochloric acid (1 M). We utilized molecular dynamics (MD) simulations, scanning electron microscopy (SEM), density functional theory (DFT), complexation, plus electrochemical impedance spectroscopy (EIS). We conducted weight loss (WL) measurements from 298 to 328 K. Inhibition efficacy reached a maximum at a BM-01 concentration of 10 -3  M, achieving 90.0% (EIS), 90.40% (WL), and 90.38% (potentiodynamic polarization (PDP)). SEM unveiled the shielding of the carbon-steel surface from acid-induced damage by BM-01. The Langmuir adsorption isotherm exhibited a robust fit with a low sum of squares, standard deviation, and a high correlation coefficient. PDP findings indicated that BM-01 acted as a mixed-type inhibitor, predominantly favoring the cathodic process, suggesting potential corrosion-mitigation properties. Theoretical analyses involving DFT, MD simulations, and radial distribution function were conducted to postulate a mechanism and identify an inhibitory layer. Theoretical outcomes aligned closely with experimental data, thereby reinforcing the validity of our findings., (© 2024. The Author(s).)

Sauerkraut-derived lactic acid bacterial (LAB) strains have gained attention due to their potential health benefits. This study focuses on evaluating seven Sauerkraut-derived RAMULAB strains isolated from sauerkraut, aiming to identify promising candidates for modulating α-glucosidase (AG) and α-amylase (AM) enzymatic functions. RAMULAB strains with remarkable probiotic potential can contribute to the digestive health and manage conditions like diabetes. Identifying robust candidates from sauerkraut, a fermented food, holds promise for natural and cost-effective probiotic sources. The RAMULAB strains underwent extensive characterization, including identification through 16S ribosomal RNA (rRNA) sequencing. Their tolerance to harsh conditions, adherence properties, antimicrobial activity, antioxidant potential, and inhibition of AG and AM were assessed. In silico analyses explored their molecular interactions, particularly with hydroxycitric acid, a potential antidiabetic compound. Among the RAMULAB strains, RAMULAB48 emerged as a standout candidate. It displayed exceptional resilience to acidic bile (≥97%), and simulated gastrointestinal conditions (≥95%), highlighting its suitability for probiotic applications. RAMULAB48 exhibited robust adherence properties, including cell-surface hydrophobicity (80%), autoaggregation (42%), coaggregation with pathogens (≥33%), and adhesion to epithelial cells. Additionally, all seven isolates demonstrated gamma-hemolysis and resistance to antibiotics (Kanamycin, Methicillin, and Vancomycin), while displaying strong antibacterial properties against foodborne pathogens. These RAMULAB strains also exhibited varying degrees of antioxidant activity, with RAMULAB48 displaying the highest potential (≥41%). In terms of antidiabetic activity, cell-free supernatant (CS) obtained from RAMULAB48 expressed the highest inhibition levels, notably inhibiting yeast AG by an impressive 59.55% and AM being by a remarkable 67.42%. RAMULAB48 produced organic acids, including hydroxycitric acid (28.024 mg/mL), which showed promising antidiabetic properties through in silico analyses, indicating favorable interactions with the target enzymes. This study identifies Lacticaseibacillus paracasei RAMULAB48, a Sauerkraut-derived RAMULAB strain, as a promising probiotic candidate with exceptional tolerance, adherence properties, antimicrobial activity, antioxidant potential, and antidiabetic effects. The presence of hydroxycitric acid further underscores its potential in managing diabetes., Competing Interests: All authors declare no conflict of interest., (© 2024 The Author(s).

Background: Rheumatoid arthritis (RA) is a debilitating inflammatory disorder characterized by an overactive immune system targeting joints, leading to inflammation and intense pain. While current RA therapies effectively alleviate symptoms, they are often associated with significant side effects. This study aimed to assess the anti-inflammatory and anti-arthritic properties of an Ethanolic Extract of Myxopyrum serratulum A.W. Hill (EEMS) using animal models., Results: The acute toxicity study with EEMS (2000 mg/kg, p.o.) on rats showed no toxicity or mortality up to the highest dose. Inflammation was induced using carrageenan, and rats were treated with varying doses of EEMS (100, 200, and 400 mg/kg, p.o.) and diclofenac to assess anti-inflammatory effects. Anti-arthritic efficacy was evaluated using Complete Freund's adjuvant (CFA)-induced inflammation, comparing EEMS to methotrexate. The results revealed dose-dependent anti-inflammatory effects of EEMS and a reversal of arthritic-induced weight loss in treated groups. Paw volume reduction was significant in both EEMS and methotrexate groups. Biochemical analyses showed elevated markers in the arthritic control group, which were normalized by EEMS and methotrexate. Notably, EEMS (400 mg/kg) significantly reduced cathepsin-D levels compared to the positive control. EEMS administration also lowered hepatic lipid peroxidation and increased endogenous antioxidants (SOD, GSH, and GPX). The 200 and 400 mg/kg doses reduced the iNOS/GADPH ratio, while the 400 mg/kg dose restored cellular and joint structure and significantly decreased IL1 levels., Conclusions: In conclusion, EEMS demonstrated substantial protective effects, mitigating health risks associated with chronic inflammation such as arthritis. These findings underscore the ethnomedical potential of Myxopyrum serratulum as a promising anti-inflammatory and anti-arthritis agent. The study suggests that EEMS could be a viable alternative or complementary therapy for RA, offering therapeutic benefits with potentially fewer side effects than current treatments., (© 2024.

Introduction: Lectins are carbohydrate-binding proteins that are extremely selective for sugar groups in the other molecules. As a result, they perform a variety of roles in biological processes involving cell, carbohydrate, and protein recognition at the cellular and molecular levels. Because lectins can bind to carbohydrates, they may play a role in determining the rate of carbohydrate digestion. They also bind to some proteins involved in diabetes mellitus (DM) pathophysiology. The present review aims to summarize the efficiency of lectins from different sources as potential antihyperglycemic agents., Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were employed for the drafting. In this regard, published scientific articles on the effects of different lectins on blood glucose (BG), glucose tolerance, hormonal effects, carbohydrate-digesting enzymes, oxidative stress, and insulin production process were collected from reputed journals using electronic databases. Furthermore, the toxicity effects of lectins from different sources were collected. A specific keyword search was completed to collect numerous articles with unique experimental designs and significant results. This was followed by the selection of the requisite articles based on the criteria designed by the authors. Data extraction was based on the common research elements included in the articles., Results and Discussion: Of 13 identified studies, 11 studies were considered after double screening based on the inclusion criteria. All 11 pharmacological investigations were considered for review. Subsequent studies reflected on the pharmacological properties of lectins on the levels of BG, oxidative stress, β-cell proliferation, insulin resistance, inhibition of carbohydrate digesting enzymes, body weight, food and water intake, lipid profile, and other parameters. This review highlights lectins as potential anti-diabetic agents., Conclusion: However, due to limited research, systematic evaluation is recommended for their development and promotion as effective potential antihyperglycemic agents. The clinical efficacy and safety of lectins against diabetes mellitus must also be evaluated., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Simha N., Patil, M.

Polysiloxanes, with poly(dimethyl)siloxane (PDMS) being the most common example, are widely used in various industrial and consumer applications due to the physicochemical properties imparted by their Si-O-Si backbone structure. The conventional synthesis of PDMS involves the hydrolysis of dichlorodimethylsilane, which raises environmental concerns due to the usage of chlorinated compounds. Herein, a biocatalytic approach for PDMS synthesis is demonstrated using silicatein-α (Silα), an enzyme from marine sponges that is known to catalyse the hydrolysis and condensation of Si-O bonds. Using dialkoxysilane precursors, it was found that Silα catalyses the formation of PDMS in non-aqueous media, yielding polymers with higher molecular weights (approximately 1000-2000 Da). However, on prolonged exposure, the gradual degradation of the polymers was also observed. Overall these observations indicate that Silα catalyses the formation polysiloxanes, demonstrating the potential of biocatalysis for more sustainable polysiloxane production.

The phytosociological survey was conducted during 2018-2020. The research area was classified into five ecological zones based on habitat, physiognomy and species composition. Pc-Ord software was used for cluster analysis and four vegetation communities were established. The Quercus baloot-Quercus incana community is situated in Sair at an altitude of 1196 (mean ± SE) m altitude with a 14.1 ± 0 slope angle and contains eleven tree species. The Pinus wallichiana- Ailanthus altissima community had a relatively small number of tree species reported in Shakawlie at 1556 (mean ± SE) with a 17.5 ± 0 slope angle. The Pinus wallichiana- Quercus incana community is distributed in Wali Kandao and Mangi Kandao at altitudes of 2030.5 (mean ± SE) m and the slope angle was 19.2 ± 1.4. This community possesses a total of twenty-one tree species and is highly diverse. Similarly, the Populus alba - Platanus orientalis group was present in Banr Pate, with an altitude of 1613 (mean ± SE) m and a 16.3 slope angle. The principal component analysis (PCA) and non-metric multidimensional scaling (NMS) ordination methods were applied to study the relationships between ecological and soil variables with trees species. The NMS ordination of axis 1 was significantly correlated with Sand% (p<0.2), Nitrogen% (p<0.1) and Pb (mg/kg) (r= 0.876751, p<0.05), while the ordination of axis 2 was significantly correlated with Silt% (p<0.2), Sand% (p<0.2), Organic matter% (p<0.2), K (mg/kg) (r=0.882433, p<0.02), Fe (mg/kg)(r=0.614833, p<0.2), Ca (mg/kg) (r=0.721712, p< 0.2) and Zn (mg/kg) (r=0.609545, p<0.2). Similarly, the PCA ordination of axis 1 revealed that it was significantly correlated with phosphorus, calcium and slope angle, while that of axis 2 was significantly correlated with altitude, zinc and manganese.

In present work, synthesis of a nanohybrid material using Fe and MoS 2 has been performed via a cost-effective and environmentally friendly route for sustainable manufacturing innovation. Rice straw extract was prepared and used as a reducing and chelating agent to synthesize the nanohybrid material by mixing it with molybdenum disulfide (MoS 2 ) and ferric nitrate [Fe (NO 3 ) 3 .9H 2 O], followed by heating and calcination. The X-ray diffraction (XRD) pattern confirms the formation of a nanohybrid consisting of monoclinic Fe 2 (MoO 4 ) 3, cubic Fe 2.957 O 4 , and orthorhombic FeS with 86% consisting of Fe 2 (MoO 4 ) 3 . The properties were analyzed through Fourier-transformed infrared spectroscopy (FTIR), atomic force microscopy (AFM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results of the dynamic light scattering (DLS) study revealed a heterogeneous size distribution, with an average particle size of 48.42 nm for 18% of particles and 384.54 nm for 82% of particles. Additionally, the zeta potential was measured to be -18.88 mV, suggesting moderate stability. X-ray photoelectron spectroscopy (XPS) results confirmed the presence of both Fe 2+ and Fe 3+ oxidation states along with the presence of Molybdenum (Mo), oxygen (O), and Sulphur (S). The prepared nanohybrid material exhibited a band gap of 2.95 eV, and the photoluminescence intensity increased almost twice that of bare MoS 2 . The present work holds potential applications in photo luminescent nanoplatform for biomedical applications., (© 2024 John Wiley & Sons Ltd.)

A series of resveratrol surrogate molecules were designed, synthesized and biologically evaluated for inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) along with anti-oxidant activity as potential novel multifunctional agents against Alzheimer's disease (AD). Six novel compounds were synthesized by reacting (E)-4-(3,5-Dimethoxystyryl) aniline with benzaldehyde and some selected derivatives of benzaldehyde in the presence of ethanol and a few drops of glacial acetic acid which followed the general scheme involved in the formation of Schiff bases. The spectral analysis data including FT-IR, 1 H-NMR, 13 C-NMR, and Mass spectroscopy results were found to be in good agreement with the newly synthesized compounds (Resveratrol Surrogate Molecules 1-6). The synthesized compounds were evaluated for their dual cholinesterase inhibitory activities, cytotoxic effect, and anti-oxidant potential. The results showed that compound RSM5 showed potent inhibitory activity against AChE and BChE. In, addition the cytotoxicity of the compound RSM5 is less and found to be within the desirable limit indicating the potential safety of RSM5. Also, it possesses substantial anti-oxidant activity which qualifies RSM5 as an anti-AD agent. Taken together, these findings demonstrate that the molecule RSM5 had the most multifunctional properties and could be a promising lead molecule for the future development of drugs for Alzheimer's treatments., (© 2024 Wiley-VHCA AG, Zurich, Switzerland.)

The primary emphasis of this study was on the innovative and scientifically valuable hydrothermal synthesis of MIL-101(Co) as a metal-organic framework (MOF) material. Subsequently, the CuFe 2 O 4 was incorporated into the MOF by a reduction-precipitation technique. The SrTiO 3 /CuFe 2 O 4 /MIL-101(Co) composite was synthesized by using hydrothermal in situ growth process. The XRD and FESEM investigations of the SrTiO 3 /CuFe 2 O 4 /MIL-101(Co) composite definitively verified its crystalline structure and proved its production with exact shape and dimensions. The data indicated that Candida albicans displayed the greatest vulnerability to all three produced materials, with reported Minimum Inhibitory Concentration (MIC) values of 500 µg mL -1 for MIL-101(Co). The CuFe 2 O 4 /MIL-101(Co) compound, when produced, exhibits MIC values of 200 µg mL -1 . Additionally, the combination of CuFe 2 O 4 /MIL-101(Co) with SrTiO 3 , shows MIC values of 50 µg mL -1 . The results also indicated that the MIC values for MIL-101(Co), and CuFe 2 O 4 /MIL-101(Co) against S. aureus were 100 µg mL -1 . Ultimately, SrTiO 3 /CuFe 2 O 4 /MIL-101(Co) exhibited identical MIC values of 50 µg mL -1 against S. aureus. The concentration of the bacterial protein was increased by adding MIL-101(Co), CuFe 2 O 4 /MIL-101(Co), and SrTiO 3 /CuFe 2 O 4 /MIL-101(Co). The antibacterial capabilities of the SrTiO 3 /CuFe 2 O 4 /MIL-101(Co) were increased after being subjected to gamma doses of 100.0 kGy. This process paves a ways for manufacturing innovation in near future., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

In the era dominated by plastic, the widespread use of plastic in our daily lives has led to a growing accumulation of its degraded byproducts, such as microplastics and plastic additives like Bisphenol A (BPA). BPA is recognized as one of the earliest man-made substances that exhibit endocrine-disrupting properties. It is frequently employed in the manufacturing of epoxy resins, polycarbonates, dental fillings, food storage containers, infant bottles, and water containers. BPA is linked to a range of health issues including obesity, diabetes, chronic respiratory illnesses, cardiovascular diseases, and reproductive abnormalities. This study examines the bacterial bioremediation of the BPA, which is found in many sources and is known for its hazardous effects on the environment. The metabolic pathways for the breakdown of BPA in important bacterial strains were hypothesized based on the observed altered intermediate metabolites during the degradation of BPA. This review discusses the enzymes and genes involved in the bacterial degradation of BPA. The utilization of naturally occurring microorganisms is the most efficient and cost-effective method due to their selectivity of strains, ensuring sustainability., (© 2024.

In this work, pure and S-N/WO3 (1%-7%) nanoparticles (NPs) have been developed for the degradation of MB dye. Optical properties, vibrational analysis, morphology, structural analysis, and photocatalytic activity of the samples have been evaluated using a variety of characterization techniques, including UV-vis, PL, FTIR, SEM, and x-ray diffraction (XRD). The XRD patterns showed that the stability of the orthorhombic phase of WO3 was affected by the concentrations of S and N. In SEM, nanospheres with an average size of 80 nm of NPs have been observed. The PL results showed that the e-, h+ recombination rate for the S-N7%/WO3 sample was the lowest. The degradation of MB dye has also been investigated in order to investigate the photocatalytic performance. Remarkably, S-N7%/WO3 shows the best results, with a maximum degradation of 90% in 120 min. The stability of the improved catalyst was tested using recycling and trapping studies. S-N7%/WO3 catalyst's exceptional photocatalytic activity highlights its potential use in wastewater treatment. This study will be helpful for manufacturing innovation., (© 2024 Author(s).

Background: Ludwig's angina is a potentially life-threatening disease characterized by diffuse bilateral cellulitis with an odontogenic origin. This unique infection is now rare owing to the antibiotic era. Case: This patient presented to the emergency room with trismus, jaw and neck swelling, mild respiratory distress with tachypnea, hyperthermia, and panic. Clinical examination and radiographic evaluation confirmed the diagnosis of Ludwig's angina. As it is a quickly spreading infection, the patient was taken up for immediate surgical decompression leading to pus drainage, removal of the offending tooth, bacterial culture and sensitivity, and administration of empirical antibiotics. As we had operated promptly, there was no need for emergency airway intervention, and the patient had immediate relief from airway distress. Conclusions: Early accurate diagnosis with conservative surgical decompression, thereby negating the need for airway intervention, was vital to avoiding mortality which is always possible in such an expeditious infection., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Vasanth S et al.)

This study reports the development of fluorometric assays for the detection and quantification of silyl hydrolase activity using silicatein as a model enzyme. These assays employed a series of organosilane substrates containing either mycophenolate or umbelliferone moieties, which become fluorescent upon hydrolysis of a scissile Si-O bond. Among these substrates, the mycophenolate-derived molecule MycoF, emerged as the most promising candidate due to its relative stability in aqueous media, which resulted in good differentiation between the enzyme-catalyzed and uncatalyzed background hydrolysis. The utility of MycoF was also demonstrated in the detection of enzyme activity in cell lysates and was found to be capable of qualitative identification of positive "hit" candidates in a high-throughput format. These fluorogenic substrates were also suitable for use in quantitative kinetic assays, as demonstrated by the acquisition of their Michaelis-Menten parameters., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.
