Case report from a 12-years old russian girl with pulmonary alveolar microlithiasis. The diagnosis was confirmed by histologic examination from biopsy specimen of the lung. The differential diagnosis and the histomorphology are discussed.

Transforming growth factor β1 (TGF-β1) is a polypeptide with various biological activities. Recent studies have shown that this and they receptors are expressed in human Leydig cells, Sertoli spermatogonia, spermatocytes sperm cells after birth, involved the endocrine regulation of spermatogenesis. However, there no report on expression TGF-β embryonic testis. TGF-β1 peptide widely distributed ...

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...

Enhanced surface photooxidation property associated with the ZnS nanoparticles caused the reduction of dissolved oxygen content in water in a dose dependent manner, when ZnS nanoparticles of different sizes are exposed to the water in various concentrations. This property was more prominent for ZnS nanoparticles with smaller sizes. Mystus tengara, exposed to ZnS nanoparticles, responded to hypo...

Formalin fixation is a mainstay of modern histopathologic analysis, yet the practice is poorly standardized and a significant potential source of preanalytical errors. Concerns of workflow and turnaround time drive interest in developing shorter fixation protocols, but rapid protocols can lead to poor histomorphology or inadequate downstream assay results. Additionally, assays such as immunohis...

background: the study of specific genes expressed in the testis is important to understanding testis development and function. spermatogenesis is an attractive model for the study of gene expression during germ cell differentiation. spermatogenesis associated-19 (spata-19) is a recently-identified important spermatogenesis-related gene specifically expressed in testis. its protein product is in...

a study was conducted to evaluate efficacyof wheat based vs. corn based diets on growth performance, carcass traits,blood parameters, jejunum morphological development, immunity, cecal microflora and excreta moisture in broiler chicks fed according to digestible essential amino acid profile. one hundred forty day old ross 308 male broiler chicks randomly distributed into ten separated floor pen...

background: given the paucity of data on possible testis changes in opioid dependents, we sought to compare the testis volumes between a group of opium dependents and a group of healthy controls. objective: comparison of testis volume between opium dependents and healthy controls. materials and methods: this case-control study recruited 100 men with opium dependency (cases) and 100 healthy men ...
