introduction: undescended testis is a common problem in children. cryptorchid testis is frequently accompanied by gross morphologic changes with regard to the size and shape of the testis, various degree of detachment between the epididymis and testis. we assessed the epididymal anomalies and patency of process vaginalis in boys with udt.   material &method;: it is a prospective study which was...

to evaluate morphological and biochemical changes of almond (prunus dulcis mill.) under salt stress conditions and determine relationship among accumulation of na and cl with these traits, an experiment was conducted based on completely randomized design with four treatments including 0 (control), 25, 50 and 75 mm of pure sodium chloride and three replications from 2010 to 2012. the seed of hea...

In this work, adsorption of the potassium amyl xanthate collector on the pure chalcopyrite surface was studied by applying atomic force microscopy (AFM). The adsorption experiments were carried out at different concentrations of the collector and at diverse pH values in the presence or absence of exterior ions. The changes occurring in the surface morphology of chalcopyrite due to the collector...

objective: a study of the histological events under interleukin-1α (il-lα) induction of bovine nasal cartilage (bnc) could result in useful data to better understand the mechanisms involved in tissue breakdown in joint diseases. the aim of this study was to investigate the effects of il-lα on chondrocyte phenotype and extracellular matrix (ecm) changes in bnc explants. materials and methods: in...

The aim of this study was to examine the possible morphological and morphometric changes resulting from vitrification of embryos at the cleavage stage. In this study, 30 mice early-cleavage embryos at different stages of cleavage, resulting from in vitro fertilization (IVF) techniques, were examined before and after vitrification. Digital images were taken from embryos before and after vitrific...

The harmful effects of ultraviolet radiation on aquatic animals, due to ozone layer reduction, have been long studied in recent years. Exposure of Rainbow Trout larvae (Oncorhynchus mykiss) to Ultraviolet-B radiation (UV-B) at different doses (68.75 µw/cm2 and 94.83 µw/cm2 as the minimum and maximum dose of UV-B in natural environment respectively) for 15 minutes once a day in dark condition in...

Although the hematology of healthy elephants has been well-described, published information on hematological changes during disease is limited. The objective of this study was to describe qualitative morphological changes in the leukocytes of Asian and African elephants (Elephas maximus and Loxodonta africana) diagnosed with a variety of inflammatory conditions. Twenty-five of 27 elephants had ...

background: amiodarone is a drug that is used for treatment of cardiac arrhythmia after cardiac ischemia. this drug as b blocker decreases arrhythmia rate but it has many side effects on different tissues. since there are rare reports about changes of lacrimal glands, this research has been carried out to study the morphological and ultrastructural changes of lacrimal gland cells after amiodaro...

microglia cells are a subset of central nervous system (cns) macrophages. changes in the cns such as injury, or developmental events, follow by morphological and physiological changes in microglia cells. in this study organotypic brain slice cultures under serum free condition were used to investigate the morphology and lectin histochemistry of microglia and macrophages in the cns in vitro. mic...
