In this study, the green treated aluminium oxide nanoparticles (Al2O3 NPs) were synthesized through simple biological reduction method and studied the effect of pH disparity on particle size variation. Green synthesis of Al2O3 NPs from Prunus × yedoensis leaf extract (PYLE) used for removal of nitrate and antibacterial activities for the first time. The synthesized Al2O3 NPs were characterized by different standard analytical and microscopy techniques. The Al2O3 NPs formation occurred through reduction of metal ions followed by nucleation. The size of the pH = 7 Al2O3 NPs are spherical and hexagonal sha...

CGNPs with a GA loading efficiency of 78 ± 2.3% were obtained through ionotropic gelation method, and they presented a spherical morphology with a diameter range of 80–100 nm. The influences of the CGNPs content on the structural, morphological, mechanical, barrier, ther...

Conclusion 99mTc-DTN can easily be synthesized using standardized optimization conditions. The radiopharmaceutical has the highest accumulation potential at targeted site induced by S. aureus without any prominent in-vivo cytotoxicity. 99mTc-DTN may be used as a potential diagnostic agent to locate S. aureus-induced infection lesions at an early stage. 99mTc-DTN can successfully discriminate between infection and inflammatory models which cannot be achieved from other radiopharmaceuticals developed in the past few decades.

This study presents a facile approach towards the preparation of bioactive and UV protective silk materials using the extract from red radish (an edible root vegetable). The adsorption mechanism of red radish extract on silk was studied. The results showed that red radish extract displayed higher exhaustion rate at lower pH. The equilibrium adsorption study indicated that the Langmuir and Freundlich isotherms were suitable to describe the adsorption behavior of red radish extract on silk, revealing that the ion−ion interactions, hydrogen bonding, and van der Waals forces play major roles in the adsorption process. Th...

ConclusionThis study shows low resistance to meropenem and tigecycline among the Enterobacteriaceae, and continued activity of linezolid, vancomycin and tigecycline against Gram-positive organisms. However, antimicrobial resistance continues to be problematic in Eastern Europe and requires continued surveillance.

In this study, we have developed arginine-glucose functionalized hydroxyapatite nanoparticle (R-G-HAp NPs) mediated novel one step transformation method, effective for both Gram-positive and Gram-negative bacteria. R-G-HAp NPs served as carriers to deliver pDNA into Escherichia coli and Staphylococcus aureus at room temperature, without the need for preparation of competent cells. High transformation efficiency was achieved in Gram-positive, S. aureus (107 cfu/μg of pDNA) as well as Gram-negative, E. coli (109 cfu/μg of pDNA). This demonstrates the efficacy of R-G-HAp NPs as a nano-vehicle to achieve high plasmid...
