Stem cell progeny often undergo transit amplifying divisions before differentiation. In Drosophila, a spermatogonial precursor divides four times within an enclosure formed by two somatic-origin cyst cells, before differentiating into spermatocytes. Although germline and cyst cell-intrinsic factors are known to regulate these divisions, the mechanistic details are unclear. Here, we show that lo...

Hydatid cyst disease is endemic, occurs following accidental ingestion of eggs released from the intestine of the definitive hosts and commonly invades the liver and the lungs. A man with a large cyst intracranial, with symptoms of intracranial hypertension and a solitary cardiac cyst is presented. The cyst was removed after suitable craniotomy. A review of the literature is presented.

hydatidosis is a parasitic disease in all over the world which is caused by a cestode (tape worm). liver, lung, and brain are the most common involved organs and involvement of muscles and bones is unusual. we report a 32years old man who had low back and radicular leg pain. he had a paravertebral mass with involvement of spinal column. this patient was operated with differential diagnosis of t...

introduction: heterotopic gastrointestinal cyst of the oral cavity is an extremely rare lesion with fewer than 40 cases reported in the english literature. it usually involves the soft tissue covering the floor of the mouth and the tongue. lining of this lesion resembles gastric or intestinal mucosa. case report: in this report we describe the lesion in two boys and discuss their pathogenesis.

background: echinococcosis is a parasitic disease with worldwide distribution which is caused by the tapeworms echinococcus granulosus . diagnosis of the disease relies on imaging techniques, but the techniques are not able to differentiate the cyst from benign or malignant tumors; hence, appropriate serologic methods are required for the differential diagnosis of the infection. materials and m...

A 56-year-old woman visited our hospital because of high fever and right hypochondralgia. Abdominal computed tomography showed a liver cyst 10 cm in diameter and dilatation of the intrahepatic bile duct. Percutaneous transhepatic drainage of the cyst guided by ultrasonography disclosed that the cyst contained a brown milky fluid, and cystography showed biliary communication. Thus, the cyst was ...

Autosomal dominant polycystic kidney disease (ADPKD) is a highly prevalent genetic disease that results in cyst formation in kidney and liver. Cytokines and growth factors secreted by the cyst-lining epithelia are positioned to initiate autocrine/paracrine signaling and promote cyst growth. Comparative analyses of human kidney and liver cyst fluids revealed disparate cytokine/growth factor prof...

Aim This study was performed to identify the non-cerebral Taenia multiceps cyst through molecular phylogeny of the 12S rRNA gene. Materials and Methods Eight cyst samples were collected from 385 examined slaughtered goats during October 2015-September 2016 from three slaughterhouses in Chittagong City Corporation. Cysts were removed from the thigh muscle, and scolices were collected for light...

Cyst enlargement in polycystic kidney disease (PKD) involves cAMP-activated proliferation of cyst-lining epithelial cells and transepithelial fluid secretion into the cyst lumen via cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel. This study aimed to investigate an inhibitory effect and detailed mechanisms of steviol and its derivatives on cyst growth using a cyst mo...

This paper proposes a segmentation method and a three-dimensional (3-D) volume calculation method of cysts in kidney from a number of computer tomography (CT) slice images. The input CT slice images contain both sides of kidneys. There are two segmentation steps used in the proposed method: kidney segmentation and cyst segmentation. For kidney segmentation, kidney regions are segmented from CT ...
