Dual Action of Nanostructured α-Mangostin-Copper Oxide Complexes Against Dental Pathogen Biofilms and Oral Cancer via Apoptosis Gene Modulation.

The development of effective treatments for dental pathogens and oral cancer remains a significant challenge. Copper oxide nanoparticles (CuO NPs) are recognized for their strong antimicrobial properties, attributed to the synthesis of oxygen-dependent radicals. α-Mangostin (MG), a natural xanthone from mangosteen fruit, is well-known for its antioxidant, antimicrobial, and anticancer potential.

Synergistic berberine chloride and Curcumin-Loaded nanofiber therapies against Methicillin-Resistant Staphylococcus aureus Infection: Augmented immune and inflammatory responses in zebrafish wound healing.

Background: Wound healing pivots on a finely orchestrated inflammatory cascade, critical for tissue repair. Chronic wounds, compounded by persistent inflammation and susceptibility to infection, pose formidable clinical challenges. Nanofiber dressings offer promising avenues for wound care, yet their interaction with inflammation and infection remains elusive.

A Systematic Review on Prevalence and Assessment of Sexual Dysfunction in Vitiligo.

Objective: Vitiligo is a common depigmenting disorder with significant psychosocial consequences. Vitiligo has been associated with psychological disorders such as depression, low self-esteem, anxiety, and sexual dysfunction (SD). In recent years, there is an increase in the number of studies looking into the impact of vitiligo on sexual functions.

Dark fermentative hydrogen production: Potential of food waste as future energy needs.

Globally, food waste (FW) is found to be one of the major constituents creating several hurdles in waste management. On the other hand, the energy crisis is increasing and the limited fossil fuel resources available are not sufficient for energy needed for emerging population. In this context, biohydrogen production approach through valorization of FW is emerging as one of the sustainable and eco-friendly options.

Applications of Neural Network-Based Plan-Cancer Method for Primary Diagnosis of Mesothelioma Cancer.

"Malignant mesothelioma (MM)" is an uncommon although fatal form of cancer. The proper MM diagnosis is crucial for efficient therapy and has significant medicolegal implications. Asbestos is a carcinogenic material that poses a health risk to humans.

Facile synthesis, physiochemical characterization and bio evaluation of sulfadimidine capped cobalt nanoparticles.

Due to their less expensive, environment friendly nature, and their natural abundance of cobalt have attained more significant attention for the synthesis of cobalt nanoparticles. In the present study, we report the facile synthesis of cobalt nanoparticles using a straight forward chemical reduction approach of cobalt chloride with sodium borohydride and capping of sulfadimidine. sulfadimidine has strong capping eligibility on the surface of nanoparticles due to its chemical stability and is an applicable as stabilizer due to the existence of an amine bond.

In vitro antimicrobial activity and comparison of the herbal extracts and sodium hypochlorite against primary plaque colonizers.

NaClO is not suitable as a root canal irrigant because of its cytotoxicity. Good biocompatibility irrigants are required to have antibacterial activity. Many herbal products like Bee glue, Noni juice and Azadirachta indica have such properties.

Differential regulation of genes by retrotransposons in rice promoters.

Rice genome harbors genes and promoters with retrotransposon insertions. There is very little information about their function. The effect of retrotransposon insertions in four rice promoter regions on gene regulation, was investigated using promoter-reporter gene constructs with and without retrotransposons.

Integrated metabolomic and proteomic approaches dissect the effect of metal-resistant bacteria on maize biomass and copper uptake.

Marginal soils arise due to various industrial and agricultural practices reducing crop productivity. Pseudomonas sp. TLC 6-6.

Machine learning approaches distinguish multiple stress conditions using stress-responsive genes and identify candidate genes for broad resistance in rice.

Abiotic and biotic stress responses are traditionally thought to be regulated by discrete signaling mechanisms. Recent experimental evidence revealed a more complex picture where these mechanisms are highly entangled and can have synergistic and antagonistic effects on each other. In this study, we identified shared stress-responsive genes between abiotic and biotic stresses in rice (Oryza sativa) by performing meta-analyses of microarray studies.

Genes and co-expression modules common to drought and bacterial stress responses in Arabidopsis and rice.

Plants are simultaneously exposed to multiple stresses resulting in enormous changes in the molecular landscape within the cell. Identification and characterization of the synergistic and antagonistic components of stress response mechanisms contributing to the cross talk between stresses is of high priority to explore and enhance multiple stress responses. To this end, we performed meta-analysis of drought (abiotic), bacterial (biotic) stress response in rice and Arabidopsis by analyzing a total of 386 microarray samples belonging to 20 microarray studies and identified approximately 3100 and 900 DEGs in rice and Arabidopsis, respectively.

Bioinformatic analysis of epigenetic and microRNA mediated regulation of drought responsive genes in rice.

Drought stress response is a complex trait regulated at multiple levels. Changes in the epigenetic and miRNA regulatory landscape can dramatically alter the outcome of a stress response. However, little is known about the scope and extent of these regulatory factors on drought related cellular processes and functions.

Cancellation of artifacts in ECG signals using block adaptive filtering techniques.

In this chapter, various block-based adaptive filter structures are presented, which estimate the deterministic components of the electrocardiogram (ECG) signal and remove the noise. The familiar Block LMS algorithm (BLMS) and its fast implementation, Fast Block LMS (FBLMS) algorithm, is proposed for removing artifacts preserving the low frequency components and tiny features of the ECG. The proposed implementation is suitable for applications requiring large signal-to-noise ratios with fast convergence rate.

Design and synthesis of tetrahydropyridothieno[2,3-d]pyrimidine scaffold based epidermal growth factor receptor (EGFR) kinase inhibitors: the role of side chain chirality and Michael acceptor group for maximal potency.

HTS hit 7 was modified through hybrid design strategy to introduce a chiral side chain followed by introduction of Michael acceptor group to obtain potent EGFR kinase inhibitors 11 and 19. Both 11 and 19 showed over 3 orders of magnitude enhanced HCC827 antiproliferative activity compared to HTS hit 7 and also inhibited gefitinib-resistant double mutant (DM, T790M/L858R) EGFR kinase at nanomolar concentration. Moreover, treatment with 19 shrinked tumor in nude mice xenograft model.

Chair to boat interconversion and face to face interactions in isomeric aryl-substituted perhydrocyclopentaquinolizines.

The structure and the conformation of the two isomeric 3,5-di(4-methoxyphenyl)perhydrocyclopenta[ij]quinolizines 1 and 2 have been determined by a combination of NOE experiments, analysis of vicinal J coupling constants, and DFT computations. The two aryl rings were found to exhibit a face to face disposition, and variable-temperature NMR spectra allowed the determination of the corresponding rotation barriers, as well as chair to boat and nitrogen inversion processes of the quinolizine rings. The structure and the conformation of the two corresponding ammonium salts 1-H+ and 2-H+ were also obtained in solution by the same techniques: in addition, their solid-state structures were determined by X-ray diffraction.
