The present study was carried out to synthesis silver nanoparticles by using Aloe Vera gel and evaluates antibacterial activity in vitro and in vivo. The synthesis and characterization of silver nanoparticles was confirmed by Ultra Violet Visible- spectrophotometer, X-ray diffraction, Fourier Transmission Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy. Reduction of the Ag+ to Ag0 during exposure to the Aloe Vera gel extract was followed by color change of the solution from colorless, yellow to dark brown within 24 hours. It is observed that surface Plasmon resonance peaks of the maximum absorbance of silver-nanoparticles occur at 425 nm, indicating that AgNPs were produced. Later on, using agar well diffusion and tube dilution method against pathogenic methicillin resistance staphylococcus aureus, (MRSA). Pseudomonas. aeruginosa and Escherichia coli, the antimicrobial properties of synthesised AgNPs were investigated. To confirm in-vivo antibacterial activity, after inducing complicated skin and soft tissue infection in mice by injecting S.aureus subcutaneously. 16µg/gm AgNPs were applied skin infected daily for three days. Silver nanoparticles were as succeeded to reduce the lesion volume in infected mice and reduce the acute inflammation symptoms as clindamycin, In conclusion, A new approach can be used to combat serious infections caused by MRSA by Aloe Vera AgNPs.

Leaky gut is a condition of increased paracellular permeability of the intestine due to compromised tight junction barriers. In recent years, this affliction has drawn the attention of scientists from different fields, as a myriad of studies prosecuted it to be the silent culprit of various immune diseases. Due to various controversies surrounding its culpability in the clinic, approaches to leaky gut are restricted in maintaining a healthy lifestyle, avoiding irritating factors, and practicing alternative medicine, including the consumption of supplements. In the current study, we investigate the tight junction-modulating effects of processed Aloe vera gel (PAG), comprising 5–400-kD polysaccharides as the main components. Our results show that oral treatment of 143 mg/kg PAG daily for 10 days improves the age-related leaky gut condition in old mice, by reducing their individual urinal lactulose/mannitol (L/M) ratio. In concordance with in vivo experiments, PAG treatment at dose 400 μg/mL accelerated the polarization process of Caco-2 monolayers. The underlying mechanism was attributed to enhancement in the expression of intestinal tight junction-associated scaffold protein zonula occludens (ZO)-1 at the translation level. This was induced by activation of the MAPK/ERK signaling pathway, which inhibits the translation repressor 4E-BP1. In conclusion, we propose that consuming PAG as a complementary food has the potential to benefit high-risk patients.

Background: Cancer along with cardiovascular diseases are globally defined as leading causes of death. Importantly, some risk factors are common to these diseases. The process of angiogenesis and platelets aggregation are observed in cancer development and progression. In recent years, studies have been conducted on nanodrugs in these diseases that have provided important information on the biological and physicochemical properties of nanoparticles. Their attractive features are that they are made of biocompatible, well-characterized and easily functionalized materials. Unlike conventional drug delivery, sustained and controlled drug release can be obtained by using nanomaterials. Methods: In this article, we review the latest research to provide comprehensive information on nanoparticle-based drugs for the treatment of cancer, cardiovascular disease associated with abnormal haemostasis, and the inhibition of tumorassociated angiogenesis. Results: The results of the analysis of data based on nanoparticles with drugs confirm their improved pharmaceutical and biological properties, which gives promising antiplatelet, anticoagulant and antiangiogenic effects. Moreover, the review included in vitro, in vivo research and presented nanodrugs with chemotherapeutics approved by Food and Drug Administration. Conclusion: By the optimization of nanoparticles size and surface properties, nanotechnology are able to deliver drugs with enhanced bioavailability in treatment of cardiovascular disease, cancer and inhibition of cancer-related angiogenesis. Thus, nanotechnology can improve the therapeutic efficacy of the drug, but there is a need for a better understanding of the nanodrugs interaction in the human body, because this is a key factor in the success of potential nanotherapeutics.
