Quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. The contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...

ecotoxicological studies that use histological techniques enjoy descriptive approach in explaining the damages to tissues. in the present study, a rank-based estimation for linear models was used to examine significant difference between levels of cypermethrin on histological changes of the liver in aphanius sophiae . the toxicity of cypermethrin associated with certain environmental factors su...

Unilateral orchidectomy (UO) is required when further breeding potential is important. It is sometimes necessary to remove a single testis in a matured stallion for therapeutic reasons. In this study, twelve donkeys were used to evaluate three techniques of unilateral castration, histological and morphological changes on the remaining testis. Results of the study showed that each of the surgica...

Endophytes are fungi that cause asymptomatic infections in leaves and stems of healthy plants. This study evaluated the presence of endophytic fungi on leaves of Rosa hybrida collected in Bogota, (Colombia) using histological techniques and light microscopy. Histological preparations showed fungal mycelium with few cells in the vascular tissue. Colonization of mesophyll cells was not observed. ...

PREMISE OF THE STUDY A novel preparation technique was developed to examine fruits and seeds of plants with exceptionally hard or brittle tissues that are very difficult to prepare using standard histological techniques. METHODS AND RESULTS The method introduced here was modified from a technique employed on fossil material and has been adapted for use on fruits and seeds of extant plants. A ...

Observation of complex cellular shapes in three-dimensional (3D) tissue context requires the use thick blocks samples, which are not transparent. To overcome this optical opacity, a specific set histological techniques have been developed and named clearing methods. Here we review major available protocols justify advantages particular protocol CUBIC over other methods imaging 3D reconstruction.
