به منظور مطالعه اثر نهادههای زیستی و مقایسه کارایی آنها با کود شیمیایی اوره بر صفات مرفولوژیکی، صفات مرتبط با کیفیت محصول، شاخصهای رشد، عملکرد سیب زمینی و اجزای آن و تداخل آن با علفهای هرز، مطالعهای در سال زراعی 89- 88 به صورت آزمایش فاکتوریل بر پایه طرح بلوکهای کامل تصادفی در چهار تکرار و سه فاکتور در مزرعه تحقیقاتی پردیس کشاورزی و منابع طبیعی دانشگاه رازی کرمانشاه انجام شد. فاکتور کود زیستی (...
HbA2' (also called Hb B2) is the most common delta-globin chain defect and is reported to occur in 1-2% of the African American population. The major clinical significance of HbA2' is that the failure to detect it might lead to an underestimation of the total HbA2, leading to failure to diagnose β-thalassemia minor. In order to diagnose β-thalassemia minor, both HbA2 and HbA2' levels must be co...
Malabari Goat populations of Tanur, Thalassery and Badagara were studied for haemoglobin polymorphism. Two variants were observed for haemoglobin, Hb A and Hb B with a frequency of 0.987 and 0.012, respectively, suggestive of three phenotypes, viz. Hb AA, Hb AB and Hb BB, and indicating the predominance of Hb A in the pooled population. Hb B variant was observed only in the Thalassery populatio...
BACKGROUND AND OBJECTIVES Anemia and hemoglobin (Hb) variability are associated with mortality in hemodialysis patients who are on erythropoiesis-stimulating agents (ESA). Our aim was to describe the degree of Hb variability present in nondialysis patients with chronic kidney disease (CKD), including those who were not receiving ESA, and to investigate the association between Hb variability and...
Heparin-binding epidermal growth factor-like growth factor (HB-EGF) has been shown to stimulate the growth of a variety of cells in an autocrine or paracrine manner. Although HB-EGF is widely expressed in tumors compared with normal tissue, its contribution to tumorigenicity is unknown. HB-EGF can be produced as a membrane-anchored form (pro-HB-EGF) and later processed to a soluble form (s-HB-E...
Background: Beta thalassemia gene mutations are among common mutations in southwest Iran. However, Hemoglobin E (Hb E) and Hb E/β⁰ thalassemia account for a small number of hemoglobinopathies in Iran. This is the first study to directly address the existence of Hb E and consequently Hb E/β⁰ thalassemia in southwest Iran. Methods: This retrospective study discovered seven cases of Hb E/β⁰ thal...
Patients with sickle cell anemia (Hb SS) or sickle cell trait (Hb AS) may present several types of renal dysfunction; however, comparison of the prevalence of these abnormalities between these two groups and correlation with the duration of disease in a large number of patients have not been thoroughly investigated. In a cross-sectional study using immunoenzymometric assays to measure tubular p...
Blood and stripped hemoglobin from Nelore cattle individuals were submitted to oxygen equilibrium experiments in both gasometric and spectrophotometric methods. No difference was detected in oxygen affinity and Bohr effect among Hb A, Hb B and Hb AB in experiments with both blood and stripped hemoglobin, in the presence and absence of the chloride ion. However, n values (Hill plots) were higher...
To determine if the activation of the (K+Cl-) cotransport system observed in hemoglobin (Hb) S- or C-containing erythrocytes is related either to a global change of isoelectric point of the Hb molecule or to the specific location of these mutations on the position 6 of the beta chain of Hb, we studied the (K+Cl-) cotransport system in erythrocytes containing beta chain variants exhibiting eithe...
