Purslane plant (Portulaca oleracea L.) is a type of wild plant that grows abundantly, but its benefits are rarely known. Purslane contains saponins, which have high antioxidant and biological activity. Skin that is sensitive to sun exposure is the issue this nanospray is targeting. The aim of this research is to determine the optimal formulation of herbal nanospray products with Purslane sunscreen to treat skin problems caused by sun exposure. The research method used was an experimental method with research stages starting from plant determination, extract making, nanospray formulation determination, preparation evaluation, in vivo UV protection activity test, and in vitro SPF test. Quantitative descriptive analysis was carried out using Microsoft Excel and SPSS Version 24. There were significant differences in erythema (lesions on the skin) between the 4 treatment groups, with significant differences in the negative control and positive control groups, as well as the group given dose treatment (the amount of extract in the nanoparticles) of 0.8 g and 0.4 g of purslane extract with the negative control. So, it can be concluded that doses of 0.8 g (SPF value: 9.9) and 0.4 g (SPF value: 8.43) of purslane extract have the potential to be sunscreens with maximum category and extra protective power. Purslane extract nanospray sunscreen has the advantage of being made from herbal ingredients, which have less potential for irritation than chemical sunscreen products.

The objective of this investigation was to determine the toxicity, anti-anemia activity, betanin content, flavonoid content, and antioxidant capacity of Beta vulgaris L. Microwave-assisted extraction (MAE) was implemented to optimize the extraction procedure. The total phenolic content (TPC) and total flavonoid content (TFC) of the extracts were determined using the Folin-Ciocalteu colorimetric and aluminum chloride methods, respectively. Furthermore, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method was employed to ascertain antioxidant capacity, whereas thin-layer chromatography was used to identify betanin content. The toxicity and anti-anemia properties were assessed in silico. The in-silico methods encompass several steps: ligand and target protein synthesis, docking of betanin compounds with the erythropoietin receptor (EpoR) target protein via SwissDock, docking data visualization via USCF Chimera, and toxicity analysis via the pkCSM and Protox online tools. The findings indicated that the beetroot extract contained a total of 34.96 ± 3.97 mg GAE/g sample of phenol. The flavonoid content of beetroot was 4.93 ± 0.33 mg QE/g sample. Qualitative analysis conducted using thin-layer chromatography yielded results indicating the presence of betanin in the extract. The IC50 value for the antioxidant activity was 97.31 μg/ml. The docking study revealed the effective interaction of betanin with several amino acid residues, suggesting a low toxicity potential, supported by toxicity class 4 and an LD50 of 305 mg/kg, and the absence of liver and Ames toxicity. It concluded that betanin is a promising anti-anemia agent. levels.

Recently,isoindoline-1,3-dione compounds based folpet, phosmet, captonand thalidomide were developed because they have a comparable degree of anti-proliferative efficacy owing to their diverse mechanisms such as HDAC inhibitors, tryptase inhibitors, inhibits the mode of tnf-α, and angiogenesis inhibitors. It was investigated how the phthalimide pharmacophore interacted with molecules such tnf-α, HDAC, VEGF, EGF, and Tyrosine Kinase Angiogenesis. In order to assess the inhibitory activity against enzyme assay, a series of phthalimidepharmacophores with various substituent’s (Schiff's base) at the N-phenyl ring were submitted to protein-ligand docking investigations using the lib-dock method in the current work. All of the compounds' chemical structures were designed using Cambridge software, ChemBioOffice Ultra 12.0, and their molecular characteristics were determined using the online molecular modelling tool Molinspiration. Utilizing the Discovery Studio Client version 4.1, ADMETlab 2.0, and Lazar 1.4.2 softwares, ADME, Toxicity, and Molecular Docking investigations using the lib-dock method were carried out to evaluate the binding mode and interactions of synthetic hits at the binding site of receptors. Docking studies demonstrated that these sorts of ligands interacted mostly with TNF-α, HDAC, VEGF, EGF, Tyrosine kinase, and angiogenesis reports, among others, by forming hydrogen bonds and interacting hydrophobically with the domain. Our docking results indicate that compounds A1, A10, A11, A22, A26, and A28 demonstrated the greatest binding affinity with the corresponding proteins based on the predicted binding energy. These computer simulations have shown that phthalimide compounds with N-phenyl rings replaced can effectively suppress enzymatic assay.

We are all interested in knowing- whether genes and drugs can increase our life-span. As per Bible, Methuselah's lifespan lasted for a total of 969 years. Recent research has identified the Methuselah gene, a specific DNA segment that holds the potential to promote robust and healthy aging. This discovery opens new avenues for the development of pharmaceutical interventions aimed at extending human lifespan. Aging, a complex process influenced by natural selection, has evolved over time, adapting to factors such as cellular senescence and genetic instability. Research on aging has extensively employed invertebrate models like cnidarians, worms, flies, and yeast. Utilizing genetic methodologies with these organisms has resulted in the identification of numerous aging genes. Remarkably, there is compelling evidence of evolutionary conservation within longevity pathways across diverse species, including mammals. In search of omic study, we would consider data from another set of experiments performed on Cnidarians and show that there has a great advanced on the `biology of aging’ in an indirect way. Cnidarians, like Turritopsis dohrnii, showcase "ontogeny reversal," reverting to earlier stages, thus achieving biological immortality through repeated rejuvenation after reproduction. Alternatively, compounds like resveratrol and rapamycin, have been identified as having the ability to decelerate aging in model organisms. However, as of now, only rapamycin has demonstrated an impact on longevity in experiments on mice. The opportunity to postpone human aging currently exists, whether through established groups of tiny molecules or numerous emerging alternatives. In this context, we explore the approaches to convert findings from age-related research into pharmaceuticals.

Reactive oxygen species (ROS) and cyclooxygenase-2 (COX-2) can be therapeutic targets for inflammatory diseases. COX-2 expression which can be triggered by ROS might consequently promote inflammation. Inhibition of ROS by the antioxidant, however, may prevent or decrease the expression of COX-2. In this study, the antioxidant and anti-inflammatory properties of the hexane (H), dichloromethane (DCM), and methanol-water (MW) extracts of marine sponges Agelas sp. (Asp), Ircinia sp. (Isp), and Aaptos suberitoides (As) were determined. The correlation between their antioxidant properties and ability to inhibit COX enzymes was also established. The MW extracts of the marine sponges and the AsDCM contain a significant (p<0>50% of the COX-2 and gave a selectivity index (COX-2/COX-1) >1.0. This suggests that the extracts can be sources of compounds with promising and selective inhibitory properties against COX-2. Correlation analysis further showed a positive linear correlation between the extracts’ inhibitory activity against the COX enzymes and their TPC, reducing power, and DPPH radical scavenging activity. Thus, the antioxidant activity of the extracts may have influenced their anti-inflammatory property via COX inhibition.

Blood glucose levels in the disease activate the free IGF-1 which promotes lipogenesis of sebaceous glands thus leading to acne formation. The study was aimed to analyze the correlation between insulin resistance and the severity of acne vulgaris. A total of 100 patients clinically diagnosed with acne vulgaris were enrolled in the study. The severity of the acne was evaluated using the GAGS system. The HOMA-IR index was used for the analysis of insulin resistance. The mean age of the patients was 22.13 years with a predominance of females i.e., 76%. GAGS score revealed 89% of patients had mild acne, 9% of patients had moderate acne and 2% of patients had severe acne. As per the HOMA-IR index cutoff value of 2.5, 35% of patients in our study had insulin resistance. A significant positive correlation was observed between the acne vulgaris and insulin resistance. Early treatment of insulin resistance can help evaluate a patient’s metabolic aspects that should be helpful in the diagnosis and treatment of various other skin conditions associated with it apart from acne vulgaris such as acanthosis nigricans, acrochordons, etc., and improving the health and the quality of care for these patients.

Metal nanoparticles typically exhibit sizes ranging from 1 to 100 nanometers and can be produced by several techniques, such as green synthesis and chemical synthesis. This study focuses on the green synthesis of copper oxide nanoparticles (CuO-NPs) using aerial extract of Christia vespertilionis. The observation of CuO-NPs formation was made based on the variations in colour exhibited by the extract mixture following the introduction of copper (II) sulphate (CuSO4). The synthesised nanoparticles underwent characterization utilising various instrumentation techniques, including UV-Vis spectrophotometry, FTIR, TEM, SEM, EDX, and TGA. The antibacterial activity of these nanoparticles was assessed by using disc diffusion method, against selected Gram-positive and Gram-negative bacteria. The investigation also encompassed an examination of the combined effect of the nanoparticles and the antibiotic Ciprofloxacin on antibacterial activity. In this study, it was noted that the maximum absorbance of the CuO-NPs occurred at a wavelength of 253nm. The functional groups of the CuO-NPs were confirmed through FTIR spectrum. TEM analysis revealed the average particle size of the CuO-NPs as 62.16 nm. Additionally, examination of SEM images revealed that the particles exhibited irregular shapes while maintaining a homogeneous distribution. The nanoparticles exhibited enhanced antibacterial efficacy against Gram-positive bacteria in comparison to the Gram-negative bacteria that were examined. Significant synergistic effect was shown when the CuoNPs were used with the antibiotic against the bacteria tested. In conclusion, the study conducted demonstrates favourable outcomes as an antibacterial agent and recommended to conduct additional research to investigate the mechanism of action and toxicity of this agent.
金属纳米颗粒的尺寸通常从1纳米到100纳米不等，可以通过几种技术生产，例如绿色合成和化学合成。本研究主要研究了绿色合成氧化铜纳米颗粒(CuO-NPs)的方法。在引入硫酸铜(CuSO4)后，根据萃取混合物所表现出的颜色变化，观察了CuO-NPs的形成。合成的纳米颗粒进行了各种仪器技术的表征，包括紫外可见分光光度法，FTIR, TEM, SEM, EDX和TGA。采用圆盘扩散法测定纳米颗粒对选定的革兰氏阳性菌和革兰氏阴性菌的抑菌活性。研究还包括纳米颗粒和抗生素环丙沙星对抗菌活性的联合作用。在本研究中，我们注意到CuO-NPs的最大吸光度出现在253nm波长处。通过FTIR光谱确定了CuO-NPs的官能团。TEM分析表明，所制备的CuO-NPs的平均粒径为62.16 nm。此外，对扫描电镜图像的检查显示，颗粒在保持均匀分布的同时呈现不规则形状。与检测的革兰氏阴性细菌相比，纳米颗粒对革兰氏阳性细菌的抗菌效果增强。当CuoNPs与抗生素一起使用时，显示出显著的协同效应。综上所述，本研究显示了作为抗菌药物的良好效果，并建议进一步研究该药物的作用机制和毒性。

This article describes the case of a previously healthy immune-competent child who, despite having received full protection against poliomyelitis with OPV, developed severe flaccid paralysis which eventually led to his death. Poliovirus testing of his contacts revealed the presence of Sabin-like type 3 poliovirus in one of them. The patient developed paralysis and respiratory distress and deceased a few months after the onset of paralysis with respiratory failure. This tragic case report demonstrates the emergence of VAPP and emphasizes the significance of early diagnosis of VAPP infections to enhance the clinical management of VAPP-infected patients.

Pyrimidinesare six-membered heterocyclic scaffold present naturally in nucleic acid components and are promising leads for the synthesis of medicinally important compounds. Cyclin-dependent kinases (CDKs) with a serine/threonine catalytic core are important druggable targets for cancer therapy and the binding of regulatory subunits controls them. In the present study series of virtually designed pyrimidine derivatives were screened using molecular docking techniques against the cyclin-dependent kinase-8 (CDK8) as a targeted protein. The density functional theory calculation of compounds having good binding affinity was done to estimate the orbital energy. The molecular dynamics simulation of the best-docked compound with the CDK8 was simulated to estimate the effect of mobility on the interactions.Themolecular docking provided insights regarding the binding ability of the designed compounds with the targeted CSK8 structure. As a result, the docked compounds exerted good interactions with the CDK8, and the compound PB129 showed the highest negative binding affinity of -12.4 kcal/mol with the formation of two hydrogen bonds. The results of the simulation study indicated that the complex of CDK-8 and PB129 hasa tight binding with constant hydrogen contacts. Moreover, the density functional theory indicated that PB129 has strong orbital energy and this compound will show tight interactions by either donating or accepting the electron with protein structure. Studied compounds showed good results for the docking study by exerting tight binding with the CDK-8 (PDB 6T41). Compound PB129 showed stable confirmation over the simulation run and has good orbital energies. Compound PB129 may act as a lead against the CDK8.
