We evaluated the morphological and functional features of hepatic cyst epithelium in adult autosomal dominant polycystic kidney disease (ADPKD). In six ADPKD patients, we investigated the morphology of cyst epithelium apical surface by scanning electron microscopy and the expression of estrogen receptors (ERs), insulin-like growth factor 1 (IGF1), IGF1 receptors (IGF1-R), growth hormone recepto...

background: improvements in imaging techniques has led to an increase in the number of diagnosed pancreatic cysts. although most of the detected cases are benign, a significant percentage of them are malignant or are potentially malignant. currently, endosonography, and analysis of cyst morphology, fine needle aspiration (fna) of the cyst contents, and measurement of the amylase and carcinoembr...

Phytoplankton cells and resting cysts of the species Scrippsiella trochoidea are regular and dominant components of the dinoflagellate flora of coastal marine waters and sediments around the world. This species is a common harmful bloom forming species in coastal waters. In this study, for the first time cyst of S. trochoidea were isolated from the sediments of southeast coast of Iran...

This species is a common harmful bloom forming species in coastal waters. In this study, for the first time cyst of S. trochoidea were isolated from the sediments of southeast coast of Iran.

In order to complete its life cycle, a cyst nematode must stimulate the production of a specialized syncytial feeding site within host root tissues. This process is characterized by major changes in local root morphology, including enlargement of affected nuclei and nucleoli, cell wall degradation, and proliferation of subcellular organelles. At the molecular level very little is known about th...

Blessed Egidio was a revered Catholic friar who lived in Basilicata (southern Italy) between the 15th and 16th centuries A.D. His natural mummy is preserved Mother Church of Laurenzana, village where he lived. During recent restoration conservation relic, palaeopathological analysis carried out. This revealed osteolytic lesions that affected maxillary bones, as two injuries were different morph...

Dear Editor, Nodular histiocytic/mesothelial hyperplasia (NHMH) is a rare and benign tumor-like lesion and easily misdiagnosed clinically and pathologically. We report a case of right spermatic cord cyst with NHMH. A 4-year-old patient presented with a right spermatic cord cyst, which developed 4 years ago. He had no history of trauma, inflammation, urinary tract infection, or surgery. Transill...

Background: Acanthamoeba is a free living ubiquitous protozoa, capable of causing Acanthamoeba keratitis (AK) of eyes and Acanthamoeba meningitis/ meningoencephalitis (AME) of central nervous system in human. Identification of amoeba is possible by a light microscope but, due to its poor resolution power, it is insufficient to distinguish the intimate sub cellular structures. As the resolution ...

The PathfinderTG biomarker panel is useful in the evaluation of pancreatic cysts that have clinical features suspicious for malignancy, but its utility in classifying fine-needle aspiration biopsies from small pancreatic cystic lesions is yet to be proven. We used morphology to classify 20 pancreatic cyst cytology aspirates, all of which met radiographic criteria for close observation. Cases we...

This is the first detailed study on the morphology of the resting cysts of an oxytrichid ciliate, Rigidohymena quadrinucleata. Resting cysts were investigated using light microscopy, SEM and TEM. The cyst wall is composed of four distinct layers (from inside to outside), namely the metacyst, the endocyst, the mesocyst and the ectocyst with spine-like protuberances. The cysts of R. quadrinucleat...
