This is a study of an antimicrobial test, including yeast, , and , on a nanosilver colloid solution. The antibiosis is compared with a standard silver ion solution at the same concentration as in the experimental process. This study proved that the nanosilver colloid prepared by the electrical spark discharge method (ESDM) is free of any chemical additives, has a microbial control effect, and that the effect is much better than the Ag standard solution at the same concentration. 3M Count Plate (YM) is used to test and observe the colony counts. The microbial control test for yeast, , and is implemented in the nanosilver colloid. In addition to , an Ag concentration of 16 ppm is enough to inhibit the growth of the samples. At the same concentration, the nanosilver colloid has a much better microbial control effect than the Ag standard solution, which may be because the nanoparticle can release Ag continuously, so the solution using the ESDM has a more significant microbial control effect.

This paper presents the effect of environmentally friendly additives on selected parameters and microbial degradation of Marine Diesel Oil (MDO). Microbiological contamination is a serious problem in MDO and other petroleum products. For this reason, it was decided to investigate the effects of environmentally friendly additives such as silver solution and colloidal nanosilver, as well as effective liquid microorganisms and ceramic tubes with different percentages of them in diesel oil (MDO) on its selected parameters and inhibition of bacterial and fungal growth.

Infected wounds caused by bacteria commonly cause delayed wound healing and even serious tissue damage, evolving into one of the most problematic clinical issues. Traditional therapies and wound dressings cannot achieve either the ideal antibiotic activity or the accelerated wound healing outcomes. Based on our previous finding that glycoproteins (PAGP) derived from medicinal animal insect Periplaneta americana L.

Blood glucose fluctuation leads to poor bone defect repair in patients with type 2 diabetes (T2DM). Strategies to safely and efficiently improve the bone regeneration disorder caused by blood glucose fluctuation are still a challenge. Neutral sphingophospholipase 2 (Smpd3) is downregulated in jawbone-derived bone marrow mesenchymal stem cells (BMSCs) from T2DM patients.

Article Synopsis
- * The experimental group received cBMMSC-infused conduits, while the control group had conduits without these cells; both groups were evaluated for neuron-like cell differentiation, neuronal regeneration, and axon growth after four weeks.
- * Various methods, including immunostaining and Western blotting, were employed to assess neural recovery and functional outcomes, such as motor ability and nerve impulse transmission, in both groups.

Self-assembled hydrogels derived from naturally sourced polymers have gained significant interest in drug delivery applications, owing to their potential, exceptional biocompatibility and sustainable properties. This work presents the development and application of self-assembled nanocomposite hydrogels from chitosan and nanosilver as a pH responsive drug delivery system for the controlled release of doxorubicin and paclitaxel in anticancer therapy. Chitosan was functionalized with 4-formyl benzoic acid for incorporating both hydrophobic and hydrophilic anticancer drugs.
