TiO2NPs
Titanium dioxide nanoparticles (TiO2 NPs) are generally used in different types of applications such as the industry of plastics, paper industry, paints, toothpaste, cosmetics, sunscreens, and in various lifestyles, because of the vast range of applications and our daily exposure to these nanoparticles and a lack of information on animal and human health this study was designed to reveal dose and time-dependent effects of TiO2-NPs on the thyroid gland and kidney functions in male rats.
For this study 54, Sprague-Dawley albino adult male rats were classified into three main groups each of 18 rats treated for a particular duration (1,2, and 4) weeks respectively. Each group was subdivided i

Nanoparticle Nanocrystal ZnO Nanoparticles
In context of this paper we prepare high purity powder ZnO nanostructures by chemical method at low temperature solution and study the effect off annealing at high temperature, ZnO nanoparticles have been successfully synthesized by chemical method at 0Cᵒ solution. In this method, suddenly reaction is occurred between zinc acetate solution and sodium hydroxide solution at 0Cᵒ, annealing temperature of powder product surfactant plays an important role in morphological changes. The nanostructures have been characterized by X-ray diffraction (XRD), Scanning Electron Microscope (SEM), differential scanning calorimetry(DSC) and UV-visible .analysis Effect of annealing temperatures on the morphology , structure and optical properties is di

Evaluation of Paromomycin Loaded Chitosan Nanoparticles and Oxidative Stress Activities against Entamoeba Histolytica
Abstract<p>This investigation was carried out to estimate the antiparasitic potential of chitosan nanoparticles loaded with paromomycin against <italic>Entamoeba histolytica</italic> infected. After rats inoculated orally in a dose 10<sup>3</sup> viable cysts for acute infection; then treated with paromomycin, chitosan nanoparticles as a single or combined therapy given for seven days. Stool examination revealed a significant decrease in the number of <italic>Entamoeba histolytica</italic> cysts in all treated infected rats compared with infected non-treated. Combined treatment provided better results than single treatment. The best effect was observed in the group </p>

Scrophularia. striata from Scrophulariacea family has been used in Iranian folk medicine for the treatment of infectious diseases. In this study we evaluated the synergistic effect of S. striata hydroalcoholic extract (SSE) and commercially available antibiotics against P. aeroginosa and Methicillin- resistant Staphylococcus aureus (MRSA). The resazurin-based microdilution method was used to determine the minimum inhibitory concentration (MIC) values of plan extract and standard antibiotics. The interaction between standard antibiotics and SSE was evaluated by using checkerboard method. The results of this study revealed that SSE enhance the antibacterial activity of antibiotics. The combin

Vancomycin Staphylococcus aureus (VRSA) is a strain of S. aureus that is considered the main cause of bacterial skin and soft tissue infections. It has acquired resistance to vancomycin and represents a therapeutic challenge. The current study aimed to compare the possible therapeutic effects of VRSA bacteriocin (VRSAcin) on the treatment of skin infection in mice with those of an antibiotic (linezolid). The results showed that of the fifty swabs obtained from human skin wounds.

Antibacterial and therapeutic effects of vancomycin-resistant Staphylococcus aureus bacteriocin (VRSAcin) in the treatment of VRSA skin infection in mice
Vancomycin Staphylococcus aureus (VRSA) is a strain of S. aureus that is considered the main cause of bacterial
skin and soft tissue infections. It has acquired resistance to vancomycin and represents a therapeutic challenge.
The current study aimed to compare the possible therapeutic effects of VRSA bacteriocin (VRSAcin) on the
treatment of skin infection in mice with those of an antibiotic (linezolid). The results showed that of the fifty
swabs obtained from human skin wounds. One isolate was selected for VRSAcin extraction depending on its
antibiotic resistance using an antibiotic susceptibility test.An agar well diffusion test was used to determine
bacteriocin’s antibacterial activity
as well as its a minimum inhibitory concentration
minimum bactericidal
concentration
and antibiofilm efficiency against gram-positive and gram-negative bacteria that were resistant to
many medicines. The freshly developed antibacterial substance VRSAcin shows promise. Bacteriocin from VRSA
was extracted and studied the optimal conditions for the Production following Purification of bacteriocin by
ammonium sulfate precipitation followed by cation-exchange chromatography. The molecular weight of
bacteriocin about (29 kDa) were determined by Sodium Dodecyl Sulfate-polyacrylamide gel electrophoresis
(SDS-PAGE). The typical conditions for the production of VRSAcin include a pH of 7 and a temperature of 37 ◦C
for 48 h. In mice
VRSA-contaminated wounds revealed severe tissue distraction and inflammation that extended
to the hypodermis
while VRSA-treated skin showed mild changes and localized lesions to the epidermis and
upper dermis. The skin of linezolid ointment-treated mice showed moderate to severe changes. In conclusion
VRSA strain infections in human burned skin were more common than expected. In vivo studies in mice indicated
that wounded skin infected with VRSA can be treated with VRSAcin as an antibacterial agent that promotes
healing processes with obvious superiority to linezolid ointment. As a result
the VRSA develops bacteriocins that
are appropriate for regulating AMR
Gram-positive and Gram-negative bacteria
and may be useful in wound
dressings.
