We compared the effects of larval and adult worm excretory-secretory (ES) products from hookworm on the proliferative responses and cytokine secretion in peripheral blood mononuclear cells (PBMCs) from hookwormpatients and egg-negative, nonendemic controls. When compared with negative controls, mitogen-stimulated PBMC from hookworm-infected individuals showed a significantly reduced proliferati...

Livestock infection by the parasitic fluke Fasciola hepatica causes major economic losses worldwide. The excretory-secretory (ES) products produced by F. hepatica are key players in understanding the host-parasite interaction and offer targets for chemo- and immunotherapy. For the first time, subproteomics has been used to compare ES products produced by adult F. hepatica in vivo, within ovine ...

Differentiation of pluripotent embryonic stem (ES) cells through multipotent neural stem (NS) cells into differentiated neurons is accompanied by wholesale changes in transcriptional programs. One factor that is present at all three stages and a key to neuronal differentiation is the RE1-silencing transcription factor (REST/NRSF). Here, we have used a novel chromatin immunoprecipitation-based c...

In this article, we describe the use of the BioMart data management system to provide integrated access to International Knockout Mouse Consortium (IKMC) data and other related mouse resources. The IKMC is currently mutating all mouse protein-coding genes in embryonic stem (ES) cells using gene targeting and gene trapping approaches. The BioMart portal allows researchers to identify and obtain ...

Introduction of excretory/secretory (ES) products of both infective-stage and newborn larvae of Trichinella spiralis into cultures of primary rat myocytes elicited morphological and structural changes in the myotubes. They appeared more granular, thinner, and failed to form networks. The most prominent lesion was the formation of 'nodular' structures, each bearing an enlarged nucleus, along the...

OCT4 is a pivotal transcription factor in maintaining the pluripotency and self-renewal capacities of embryonic stem (ES) cells. Human OCT4 can generate two isoforms by alternative splicing, termed OCT4A and OCT4B. OCT4A confers the stemness properties of ES cells, whereas the function of OCT4B is unknown. We present here the diverse protein products and a novel function of OCT4 gene. A single ...

We developed a method to generate dendritic cells (DCs) from mouse embryonic stem (ES) cells. We cultured ES cells for 10 days on feeder cell layers of OP9, in the presence of granulocyte-macrophage colony-stimulating factor in the latter 5 days. The resultant ES cell-derived cells were transferred to bacteriologic Petri dishes without feeder cells and further cultured. In about 7 days, irregul...

BACKGROUND AND AIM: This study was performed to evaluate and compare the calcification patterns of the stylohyoid ligament in Eagle’s syndrome (ES) patients, and asymptomatic patients with elongated styloid process (SP) via cone-beam computed tomography (CBCT).METHODS: A total of 52 CBCT images in two symptomatic (ES) and asymptomatic groups (n = 26 per group) were assessed. The mean length an...

background: the aim of this study was to compare superoxide dismutase (sod) activity in fasciola hepatica and fasciola gigantica parasites. materials: f. gigantica and f. hepatica helminths were collected from abattoir and cultured in buffer media for 4 h at 37 °c. excretory-secretory (es) products were collected, centrifuged and stored at - 20 ◦ c. e-s protein concentration was measured by bra...
