Chitosan-based nano-scaffolds as antileishmanial wound dressing in BALB/c mice treatment: Characterization and design of tissue regeneration.

Objectives: Rapid healing of cutaneous leishmaniasis as one of the most important parasitic diseases leads to the decrease of scars and prevention of a great threat to the looks of the affected people. Today, the use of nano-scaffolds is rapidly increasing in tissue engineering and regenerative medicine with structures similar to the target tissue. Chitosan (CS) is a bioactive polymer with antimicrobial and accelerating features of healing wounds, which is commonly used in biomedicine.

The effects of hydroalcoholic extract of Vaccinium arctostaphylos L. on sperm parameters, oxidative injury and apoptotic changes in oxymetholone-induced testicular toxicity in mouse.

Anabolic androgenic steroids (AAS) such as oxymetholone (OM) used for athletic enhancement, but increased free radicals damage and changes in hormonal levels, lead to serious and irreversible organ damage. Vaccinium arctostaphylos(V. arctostaphylos( has been demonstrated to have antioxidant and antiinflammatory effects.

Bioclimatic Analysis and Spatial Distribution of Livestock Fascioliasis in Iran.

Background: This study aimed to investigate the prevalence of fascioliasis and to perform a climatological analysis of different regions of Iran based on the current situation of the parasite and its intermediate host using Geographical Information System (GIS).

Methods: Meteorological data were obtained from Iran Meteorological Organization. Risk map of fascioliasis transmission was prepared based on this data and using forecasting indices.
