Scientific Study of your Room-Level Localization System According to Bluetooth Low Electricity Beacons.
Exercise-induced fatigue is accumulated when lactic acid cannot be timely eliminated after intensive exercise, resulting in sport injuries. Traditional lactic acid removal methods are limited in timeliness, metabolic burden, and potential toxicity. To solve the thorny problems, in this study, nanomedicine was introduced for lactic acid removal. Magnesium trisilicate was coated on the surface of magnetic nanoparticles. These nanoparticles exhibited a prompt and efficient lactic acid adsorbing behavior. Moreover, they have favorable magnetic properties and good biocompatibility. The results showed that the prepared nanoparticles hold great potential in the removal of lactic acid for preventing exercise-induced fatigue.Here, an unprecedented synthesis method for nickel oxide nanoparticles (NiO-NPs) was facilitated using Salvia hispanica leaf extracts with the assistance of a high gravity rotating packed bed (RPB) system that enabled fast mass transfer and molecular mixing. The synthesized nanoparticles were anchored on the surface of biodegradable chitosan nanobeads and their photocatalytic activity was evaluated by the degradation of methylene blue. Additionally, the potential biological activities of NiO-NPs in terms of antibacterial (Staphylococcus aureus and Escherichia coli for 24 hours), cytotoxicity (using the PC12 cell line for 24 and 72 hours), and antioxidant activities (based on the discoloration of the methanolic solution of DPPH) were assessed. This novel approach for NiO-NPs@Chitosan synthesis as mediated by a renewable plant extract and facilitated by a high-gravity method, led to the greener synthesis of nanoparticles with significant antibacterial and photocatalytic properties.The clinical studies proved the adverse effect of Propranolol on sexual function. Regarding this issue, the key research question of this study was, whether the designed herbal nanohybrid formula EGCG-chitosan-alginate has an efficacy versus Propranolol, or not? The formula was optimized according to the coacervation method. Its molecular structure and characteristics were confirmed. The entrapment efficiency was determined, and the stability, as well in vitro release study was conducted. The in vivo study was conducted for 65 days. To answer the raised question, tissue weights of the testis, epididymis seminal vesicles, and prostate were determined. Docetaxel in vitro Oxidative stress markers as MDA and GSH were measured in testis and epididymis, while testosterone in blood serum. The semen analysis was performed. DNA damage was detected according to the comet assay procedures. Conventional pathological examination was done in special concern to testis and epididymis. The characterization results reflected the good preparation EGCG versus propranolol.To minimize the hazardous effect of physical and chemical synthesis of nanoparticles we focused on the green synthesis of nanoparticles. Nanotechnology is a research hotspot and catch great attention because of its versatile applications in medical, biosciences and engineering fields. Purpose of our recent study is to synthesize bio-inspired metallic silver NPs by root mediated Zingiber officianale extract. The synthesized Ag-NPs were further characterized by using UVVisible spectroscopy, XRD, EDX, SEM, TEM and DLS techniques. The extent of crystallites were confirmed by X-ray diffraction. SEM and TEM revealed the morphological features with size of nanoparticles between 17.3 and 41.2 nm. FTIR analysis confirmed the capping of nanoparticles by bio active constituents present in Zingiber officinale extract. Later EDX confirmed the elemental composition of nanoparticles. Zeta potential, PDI and hydrodynamic size of Ag-NPs were confirmed by DLS. The synthesize Ag-NPs possess eminent biological potency against bae of Ag-NPs was observed against fresh RBCs making the ecofriendly biosynthesized silver NPs a multi-dimensional candidate in biomedical field.There is continued interest in Nano Carbon Materials (NCMs) and two of these, Fullerene C60 and Graphene have received Nobel prizes. Low solubility in most solvents has been a stumbling block in their industrial use. We report here the successful synthesis of a new water soluble tri-adduct of Fullerene C60 using a two-step procedure to obtain the water soluble s-Tri-(1-aziridino-2, 3-dimethoxy-benzene-5-carboxylato-6-carboxylic acid)-H-Fullerene C60-Manganese (II) Complex ( III ). Matrix Assisted Laser Desorption Ionization Mass Spectrometry (MALDI-MS) and Electron Paramagnetic Resonance (EPR) studies critically helped recognize the presence of an atom of Manganese in the complex. The new complex was also characterized by Ultra violet-Visible (UV-Vis.). Fourier Transform-Infra Red (FT-IR) spectroscopy, Energy Dispersive X-ray analysis (EDAX), Scanning Electron Microscopy (SEM), Thermal Gravimetric Analysis (TGA), and powder X-ray diffraction. The new compound has been shown to possess anti-cancer activity comparable to Doxorubicin, currently the most used anti-cancer drug. This new water soluble Fullerene C60-Manganese (II) tri-adduct complex ( III ) thus holds much promise for the fields of biology, biochemistry, medicine, and materials science.We developed a vaccine formulation containing ApoB derived P210 peptides as autoantigens, retinoic acid (RA) as an immune enhancer, both of which were delivered using PLGA nanoparticles. The formula was used to induce an immune response in 12-week-old male Apoe-/- mice with pre-existing atherosclerotic lesions. The nanotechnology platform PRINT® was used to fabricate PLGA nanoparticles that encapsulated RA inside and adsorbed the P210 onto the particle surface. In this study, we demonstrated that immunization of Apoe-/- mice with the formulation was able to considerably attenuate atherosclerotic lesions, accompanied by increased P210 specific IgM and another oxidized lipid derived autoantigen, M2AA, specific IgG autoantibodies, and decreased the inflammatory response, as compared to the P210 group with Freund's adjuvant. Our formulation represents an exciting technology to enhance the efficacy of the P210 vaccine.Among different forms of metallic nanoparticles (NPs), zinc oxide (ZnO) NPs with a very special bandgap of 3.37 eV and considerable binding energy of excitation (60 meV at room temperature), have been classified as high-tech nanoparticles. This study aimed to synthesize ZnO NPs using the extract from Salvia hispanica leaves. The synthesized nanoparticles were fully characterized and the photocatalytic activity was evaluated through the degradation of methylene blue. Additionally, the potential in vitro biological activities of such ZnO NPs in terms of their antibacterial activity were determined, as well as their antioxidant (30 minutes), antiviral (48 hours) and mammalian cell viability properties (48 and 72 hours). This study is the first investigation into the synthesis of such green ZnO NPs mediated by this plant extract, in which both photocatalytic and biomedical properties were found to be promising. The IC50 values for the antibacterial activities were found to be around 17.4 μg mL-1 and 28.5 μg mL-1 for S.
