Despite significant biological effects, the clinical use of chrysin has been restricted because of its poor oral bioavailability. <P> Objective The purpose of the present research was to investigate the targeting potential of Mannose decorated chrysin (5,7- dihydroxyflavone) loaded solid lipid nanocarrier (MC-SLNs) for gastric cancer. <P> Methods The Chrysin loaded SLNs (C-SLNs) were developed optimized, characterized and further mannosylated. The C-SLNs were developed with high shear homogenizer, optimized with 32 full factorial designs and characterized by Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM) and evaluated for particle size/polydispersity index, zeta-potential, entrapment efficiency, % release and haemolytic toxicity. The ex-vivo cytotoxicity study was performed on gastric cancer (ACG) and normal cell lines. <P> Results DSC and XRD data predict the chrysin encapsulation in lipid core and FTIR results confirm the mannosylation of C-SLNs. The optimized C-SLNs exhibited a narrow size distribution with a particle size of 285.65 nm. The % Entrapment Efficiency (%EE) and % controlled release were found to be 74.43% and 64.83%. Once C-SLNs were coated with mannose, profound change was observed in dependent variable - increase in the particle size of MC-SLNs (307.1 nm) was observed with 62.87% release and 70.8% entrapment efficiency. Further, the in vitro studies depicted MC- SLNs to be least hemolytic than pure chrysin and C-SLNs. MC-SLNs were most cytotoxic and were preferably taken up ACG tumor cells as evaluated against C-SLNs. <P> Conclusion These data suggested that the MC-SLNs demonstrated better biocompatibility and targeting efficiency to treat the gastric cancer.
Conclusion These data suggested that the MC-SLNs demonstrated better biocompatibility and targeting efficiency to treat the gastric cancer.
Lung adenocarcinoma (LADC) is the most common type of lung cancer and is a subtype of non-small-cell lung cancer (NSCLC). Approximately 40% of LADC patients experience brain metastases (BMs) during the course of the disease. In this study, integrated bioinformatics methods were applied to identify key genes related to brain metastasis in lung adenocarcinoma.

We derived and characterized genes differentially expressed between the primary tumour and brain metastases using tumour cells isolated from two lung cancer Patient-derived xenografts (PDX) cases (GSE 69405). Gene ontology (GO) and KEGG pathway enrichment analyses were applied, and protein-protein interaction (PPI) networks and Cytoscape software were utilized to identify key genes.

Four key genes including CKAP4 (Cytoskeleton Associated Protein 4), SERPINA1 (Serpin Family A Member 1), SDC2 (Syndecan 2) and GNG11 (G Protein Subunit Gamma 11) were identified for BM-LADC by the Venn diagram.

We believe these key genes may be potential biomarkers for improved prognosis and treatment of lung adenocarcinoma.

It is a microvascular complication that impairs the vision of diabetic individuals and can cause acquired blindness. Currently available treatment options like laser therapy, vitrectomy, intravitreal anti-vascular endothelial growth factor (VEGF) agents, and glucocorticoids help to reduce vision loss at advanced stages. In spite of the available therapies, patients with severe vision loss face difficulty in achieving normal vision. There is a need for development of newer treatment strategies to address the condition from the early stages. Multiple factors owing to complex pathophysiological events are responsible for this long-term complication. Neurodegeneration, inflammation, and oxidative stress are the three important factors associated with the development of DR. Oxidative stress is a major contributor to the onset and progression of DR. click here Pathological events like retinal neurodegeneration and inflammation damage the retina rhibitors is the third combination. This combination may help to manage diabetic macular edema. The main purpose of this article is to discuss the link between these pathologies and the three combination approaches with the objective of consideration of newer therapeutic approaches in research related to DR treatment.ACE2 has long been known as an injury protective protein, it can protect a variety of organ damage such as heart, liver, kidney and lung. Especially in cardiovascular diseases, ACE2, as a negative regulator of RAAS, is an extremely important protective factor that mainly plays a role by converting Ang Ⅱ to Ang-(1-7). Nevertheless, with the recent outbreak of COVID-19, it was exposed that another identity of ACE2 is the entry receptor for SARS-CoV-2, which previously served as the entry receptor for SARS. With the in-depth clinical research, it was found that the severity and susceptibility of COVID-19 are related to cardiovascular disease, and SARS-CoV-2 binding to ACE2 receptor is also potentially associated with heart injury symptoms. Therefore, in this article, we mainly review the relationship between ACE2, COVID-19 and cardiovascular system diseases/heart injury.
Pentacyclic triterpenoids are a biologically active class of phytoconstituents with diverse pharmacological activity including anti-inflammatory action.

In the current study, we isolated 3-Acetylmyricadiol, a pentacyclic triterpenoid, from the ethyl acetate bark-extract of Myrica esculenta and evaluated it for anti-inflammatory potential.

The ethyl acetate bark-extract of the M. esculenta was subjected to column chromatography to isolate 3-Acetylmyricadiol. MTT assay was performed to check cell viability. The production of proinflammatory mediators like Nitric oxide, IL-6, TNF-α was observed after administration of 5, 10, 20 μM of 3-Acetylmyricadiol in LPS-activated Raw 246.7 macrophages by the reported methods.

MTT assay indicated more than 90% cell viability up to 20 μM of 3-Acetylmyricadiol. The administration of 3-Acetylmyricadiol inhibited the production of Nitric oxide, IL-6, TNF-α in a dose-dependent manner significantly in comparison to LPS treated cells. The maximum effect was observed at 20 μM of 3-Acetylmyricadiol which resulted in 52.
