Opis:
Antibiotics are used for postsurgical wound healing purposes but unfortunately, resistance against them demands some alternatives for quick recovery. Sepsis of wounds is a challenge for medical as well as veterinary professionals. Nanoparticles have significant advantages in wound treatment and drug resistance reversal. This study was conducted to appreciate emerging alternates of antibiotics like zinc oxide nanoparticles and plant extracts in topical application. Zinc oxide is considered a good wound healer and its nanoparticles are easy to access. So, the efficacies of zinc oxide nanoparticles and sweet flag plant extract ointments were tested to compare modern and traditional therapeutics as sweet flag is considered a pure medicinal plant. Rabbits were selected for this study due to the healing properties of their skin. Wounds were inflicted on the thoracolumbar region and treated for 29 days post-surgically daily with normal saline and the ointment of zinc oxide nanoparticles and sweet flag extract ointment, prepared in a hydrophilic solvent. Wound shrinkage was observed daily and histopathological analysis was made and results were compared. Zinc oxide nanoparticles ointment showed the most satisfactory results for every parameter included in the study. No side effects of its topical application were observed. Healing was normal without any complications. The preparations of zinc oxide nanoparticles may help in the era of antibiotic resistance as topical drugs in the future.

Opis:
The present study was focused on the technical feasibility of using immobilized hybrid biomass of Pleurotos sajor-caju and sunflower for Pb(II) removal from the contaminated water. After preliminary evaluation, it was found that immobilized hybrid biomass of Pleurotos sajor-caju and sun-flower effectively removed Pb(II) from wastewater at pH 4.5. The effect of various experimental parameters on Pb(II) uptake by hybrid biosorbent was systematically evaluated in a batch biosorption system. The optimized biosorbent dose, contact time, initial metal concentration and temperature were 0.05 g/100 cm 3, 180 min, 800 mg/dm3 and 60 °C. Dynamics of the adsorption process were studied, and the values of rate constants of pseudo first order and pseudo second order kinetic models were calculated. Equilibrium isotherms for the adsorption of Pb(II) were analyzed by the Langmuir and Freundlich isotherm models. The sorption of Pb(II) followed the pseudo second order kinetic model. The Langmuir sorption isotherm fitted well to Pb(II) concentration data. The results revealed that this new hybrid biosorbent system was a promising candidate for eliminating Pb(II) from contaminated aquatic environment.

Opis:
Introduction. Molecular studies have confirmed the silent circulation of enterovirus (EntV) and hepatitis A virus in the environment, even in the absence of clinical manifestation. Viral pathogens are among the major causes of disease outbreaks, particularly in the bigger cities and both in the developed and underdeveloped nations. Materials and method. Between June 2016 – June 2017, 97 samples of drinking water, river water polluted with sewage and blood were selected and obtained from high risk communities in Pakistan. Negatively charged membrane filters were used to concentrate the virus, followed by the use of specific PCR primers set for quick identification of the waterborne viruses. Results. Enteroviruses were recovered from 40%, 28.57% and 33.33% of river water polluted with sewage samples in Lahore, Islamabad and Rawalpindi, respectively, while the presence of 13.13% and 11.76% of viral load was also confirmed in the drinking water of Lahore and Rawalpindi, respectively. A high prevalence of HAV (12.5% and 21.05%) was also verified in the clinical samples. Phylogenetic analysis indicated close resemblance of HAV isolates with the Indian strains. This study is the first ever comparative analysis of the EntV and HAV isolated from environmental samples and clinical specimen on a molecular level. Conclusions. The parallel surveillance of EntV and HAV in the river water polluted with sewage, and clinical samples is quite helpful for controlling and reducing the disease burden of the waterborne illnesses.
