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...

The polarized organization of epithelial cells is required for vectorial solute transport and may be altered in renal cystic diseases. Vesicle integral protein of 17 kDa (VIP17/MAL) is involved in apical vesicle transport. VIP17/MAL overexpression in vivo results in renal cystogenesis of unknown etiology. Renal cystogenesis can occur as a consequence of defects of the primary cilium. To explore...

In the genus Entamoeba, actin reorganization is necessary for cyst differentiation; however, its role is still unknown. The aim of this work was to investigate the role of actin and encystation-related proteins during Entamoeba invadens encystation. Studied proteins were actin, RhoA, a small GTPase involved through its effectors in the rearrangement of the actin cytoskeleton; Rab11, a protein i...

The aim of this pictorial essay is to describe the ultrasound characteristics of the mucocele of the appendix (MA) by transvaginal ultrasound. The databases of the pathology and gynaecology departments of two Belgian hospitals were retrospectively searched for all cases of MA. Only patients who received a pre-operative transvaginal ultrasound scan by an experienced ultrasound examiner following...

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 ...

Aneurysmal bone cyst rarely affects the skull. We report two cases of aneurysmal bone cyst of the frontal bone. One of the cases is associated with pregnancy. The association of pregnancy with aneurysmal bone cyst and enlargement of the aneurysmal bone cyst during the pregnancy have been discussed.

To report on an epithelial inclusion cyst of the iris that was successfully treated with needle aspiration and Ab externo laser photocoagulation. A 6-year-old boy was treated for a 6.0 mm fluid-filled cyst in the anterior chamber of the right eye. Thirteen months previously, he had undergone primary closure of a 6 mm full-thickness corneal laceration. The subsequent cyst was diagnosed as an epi...

Iris cysts can arise from iris pigment epithelium or stroma. We present 3 cases of iris cysts which have been managed in different ways. In a one-month neonate, cyst was punctured with keratome and gentle diode laser endophotocoagulation was applied to the base. A2.5-month infant presented with watering and blepharospasm since birth. Clear fluid was aspirated from the cyst with a 27-gauge needl...

We herein describe a case involving spontaneous rerupture of a nonparasitic liver cyst successfully treated with cyst fenestration and an omental flap. A 59-year-old Japanese woman was transferred to our hospital for evaluation of acute abdominal pain. She had a history of conservative treatment with antibiotics for spontaneous rupture of a liver cyst 1 month previously. On arrival, she exhibit...
