Human embryonic stem (ES) cells are undifferentiated, pluripotent cells that can be maintained indefinitely in culture. Here we demonstrate that human ES cells differentiate to hematopoietic precursor cells when cocultured with the murine bone marrow cell line S17 or the yolk sac endothelial cell line C166. This hematopoietic differentiation requires fetal bovine serum, but no other exogenous c...
Acanthamoeba is a free-living amoeba commonly present in the environment and often found in human airway cavities. Acanthamoeba possesses strong proteases that can elicit allergic airway inflammation. To our knowledge, the aeroallergenicity of Acanthamoeba has not been reported. We repeatedly inoculated mice with Acanthamoeba trophozoites or excretory-secretory (ES) proteins intra-nasally and e...
یونجه یکی از گیاهان علوفهای است که به علت میزان پروتئین بالا، خوشخوراکی، قابلیت هضم بالا و سازگاری آن در شرایط مختلف محیطی اهمیت بالایی دارد. در این تحقیق تنوع ژنتیکی نوزده نژادگان (ژنوتیپ) از گونۀ Medicago sativa با استفاده از نشانگرهای سیتوژنتیکی و مولکولی بررسی شد. بر پایۀ داده‌های سیتوژنتیکی تنوع معنیداری برای صفات کاریوتیپی وجود داشت. نژادگان‌های 211-ES (اصفهان1)، 027-ES (شاهرود)، 19...
Exsheathing fluid (EF) and excretory-secretory products (ES) of infective third-stage cultured larvae ofOstertagia circumcincta were analysed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDSPAGE). Five and seven predominant proteins were found in the EF and ES products, respectively. Immunoblotting by sheep pre-infection serum did not react with any of the EF and ES proteins, b...
Malaria therapy, experimental, and epidemiological studies have shown that erythrocyte Duffy blood group-negative people, largely of African ancestry, are resistant to erythrocyte Plasmodium vivax infection. These findings established a paradigm that the Duffy antigen is required for P. vivax erythrocyte invasion. P. vivax is endemic in Madagascar, where admixture of Duffy-negative and Duffy-po...
Antibodies against phycobilisom es o f Porphyridium cruentum immunoreact with B-phycoerythrin from the same organism. A strong antigen-antibody com plex is not only formed with the native B-phycoerythrin but also when the chromophore is chemically reduced, split or even degraded with chromic acid. Characteristics o f precipitations and dissolutions in the presence of the chaotropic reagents ure...
Purpose: Parkinson's disease is a degenerative disease produced by the death of dopaminergic neurons, and the response to current treatments is varied. It is important to develop a model for the evaluation of ES cells as an alternative model for treatment. Materials and Methods: The model for PD was developed in rats. First, ES cells were transplanted into experimental models in three groups: ...
An embryonic stem (ES) cell/OP9 coculture system for the effective production of functional neutrophils is described. A 3-step differentiation strategy was developed that uses liquid culture, enabling reliable and abundant production of neutrophils at high purity without the need of sorting for isolation of mature neutrophils. Use of the OP9 stromal cell line significantly enhances the number, ...
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...
