Human induced pluripotent stem cells (hiPSCs) are a promising cellular source in cell therapies or regenerative medicine and they allow to address fundamental mechanisms embryo-genesis. However, their culture provide large amounts of high quality remains challenging. Here, using an encapsulation microfluidic device, we observe that hiPSCs self-organize into cysts, which spherical closed epithel...

Abstract:  The surface morphology of resting eggs of Anostracan species from East Azerbaijan Province of Iran and that of Artemia urmiana was compared using Scanning Electron Microscopy (SEM). Anostracan fauna of East Azerbaijan temporary pools were determined as follows: Chirocephalus skorikowi (Chirocephalidae), Branchinecta orientalis (Branchinectidae), Streptocephalus torvicornis (St...

As the effectiveness of mebendazole and albendazole in patients with echinococcosis has been found to vary, we investigated some of the factors likely to be responsible. A total of 79 patients who were treated with mebendazole (44 patients) or albendazole (35 patients) were included in the study. Evaluation of the treatment results was based on the changes in cyst morphology, as evidenced by th...

background: no data is available on morphology and genetic characteristics of echinococcus granulosus derived from donkeys of iran, despite of its existence in donkeys.in the present study morphometric variations of the rostellar hooks of protoscoleces and genotype characteristics of hydatid cyst of donkey from iran were determined. methods: protoscoleces prepared from hydatid cyst of donkey of...

Haematococcus pluvialis is a freshwater species of green algae and is well known for its accumulation of the strong antioxidant astaxanthin, which is used in aquaculture, various pharmaceuticals, and cosmetics. High levels of astaxanthin are present in cysts, which rapidly accumulate when the environmental conditions become unfavorable for normal cell growth. It is not understood, however, how ...

Detailed morphological comparisons with light and scanning electron microscopy were made of white females and cysts of several isolates of Globodera tabacum sspp. tabacum (GTT), virginiae (GTV), and solanacearum (GTS). Observations focused on body shape, anterior region including head shape, lip pattern, stylet morphology, and the terminal area in females; and body shape and terminal area of cy...

BACKGROUND & AIMS Cysts of the pancreas display a wide spectrum of histology, including inflammatory (pseudocysts), benign (serous), premalignant (mucinous), and malignant (mucinous) lesions. Endoscopic ultrasonography (EUS) may offer a diagnostic tool through the combination of imaging and guided, fine-needle aspiration (FNA). The purpose of this investigation was to determine the most accurat...

CONTEXT Molecular analysis of pancreatic cyst fluid obtained by EUS-FNA may increase diagnostic accuracy. We evaluated the utility of cyst-fluid molecular analysis, including mutational analysis of K-ras, loss of heterozygosity (LOH) at tumor suppressor loci, and DNA content in the diagnoses and surveillance of pancreatic cysts. METHODS We retrospectively reviewed the Columbia University Panc...
