According to modern animal welfare legislation, animals should be protected from suffering and lasting harm not for the benefit of us humans as in earlier anthropocentric conceptions, but in their own interest. The driving force behind animal protection is our empathy with animals which triggers feelings of compassion. Empathy with animals most likely is a psychological side-effect of adaptive ...

background: in the present study, the submandibularsalivary gland microscopic morphology of the adult africangiant pouched rat was investigated. this study was carried out toprovide the basic histology of this organ in the giant pouched rat,to accompany the dearth of information of its microscopicarchitecture in the available literature. this becomes of evenhigher importance when considering th...

skin lesions were found in two 3–4-year-old holstein cows in a dairy farm in shiraz. lesions were distributed mostly around the neck, forelimbs, hindlimbs, and bilateral of midline portion and varied from nodule-like structure to patch with extensive accumulation of crust. skin scraping samples were taken from each animal and direct smears were prepared, stained with giemsa and observed under a...

The effect of air quality on human?s health has been extremely studied, nanoparticles in can cause various diseases and even lead to death. However, the non-digestible from food physical mental seriously ignored, no report was seen open literature. This paper uses silkworm as an experimental subject by feeding throughout their life, results show that greatly change animal?s body morphology, beh...

the tadpole shrimp of genus triops is a well-known living fossil whose fundamental morphology has been unchanged for 220 million years. we collected specimens of triops cancriformis in temporary water bodies near the southern part of urmia lake (in the fall of 2005). some biological characteristics of this triops were investigated. the feeding re-gime of t. cancriformis was found to be related ...

Background Morphine as a natural alkaloid (opiate) is considered as one of the problems associated with poor semen production and sperm quality. For the first time, this experimental study was carried out to evaluate the impact of intra-peritoneal injection of morphine on sperm parameters, chromatin quality and DNA integrity of spermatozoa aspirated from cauda epididymis of mice. MaterialsAndMe...

It is generally accepted that animal-fluid interactions have shaped the evolution of animals that swim and fly. However, the functional ecological advantages associated with those adaptations are currently difficult to predict on the basis of measurements of the animal-fluid interactions. We report the identification of a robust, fluid dynamic correlate of distinct ecological functions in seven...

The main goal of this research was to compare the in vitro release rates of nano- and microcapsules of Silybum marianum extract (SME) in animal simulated gastric and intestinal medium conditions. The extract was encapsulated within sodium alginate carriers using emulsification/internal gelation method. Particle size, zeta potential, polydispersity index (PDI) and morphology of...
