In order to better understand the chiral recognition mechanisms of positively charged cyclodextrin (CD) derivatives, synthesis, pKa determination by 1H nuclear magnetic resonance (NMR)-pH titration and a comparative capillary electrophoretic (CE) study were performed with two series mono-substituted cationic single isomer CDs. The first selectors mono-(6-N-pyrrolidine-6-deoxy)-β-CD (PYR-β-CD), ...

alzheimer’s disease (ad) is a neurodegenerative disorder and the most common form of dementia. almost 47 million people suffer from dementia worldwide. ad accounts for approximately 60%–80% of all dementia cases. three major pathologies characterize the disease: senile plaques, neurofibrillary tangles and inflammation. we review the literature on events contributing to the inflammation. those i...

background: β-thalassemia as a hereditary disease is defined as defective synthesis of   β-globin chains, resulting in erythropoiesis abnormalities and severe anemia. different studies have shown that cytokines and cytokine gene polymorphisms play a major role in the pathogenesis of   β-thalassemia. single nucleotide polymorphisms (snps) within the promoter region or other regulatory sequences ...

Background and objectives: Plumeria rubra L. (Apocynaceae) is a deciduous shrub or small tree cultivated in subtropical and tropical countries.  Its bark is prescribed to treat amoebic dysentery,   dropsy, jaundice, scabies, gonorrhea, venereal affections and wounds. In the present research, we aimed to isolate and identify the chemical constituents of the bark of ...

Background and objectives: Humulus lupulus, a plant belonging to the family Cannabaceae, is used as a medicinal plant with therapeutic applications in different nations. In this study, two samples of H. lupulus (vernalized and wild hops) were selected for further analysis about differences of their essential oils. Methods: The essential oils f...

conclusions: hydroxyurea can be safely used in some transfusion-dependent β-thalassemia patients to decrease their transfusion needs. background: β-thalassemia is an inherited hemoglobin disorder caused by defective synthesis of ß-globin chains. hemoglobin (hb) f induction is a possible therapeutic approach which can partially compensate for α and non-α globin chains imbalance. objectives: we a...

background: β-thalassemia is a common autosomal recessive disorder resulting from over 200 different mutations of beta glo­bin genes. the aim of the present study was to identify the distribution and frequency of the most com­mon β-thalassemia mu­tations among the population of isfahan province in central iran. methods: the data presented here were derived from a total of 114 β-thalassemia chro...

background: several cells of immune system such as regulatory t cells and macrophages secrete transforming growth factor-β (tgf-β) in response to different stimuli. this cytokine has inhibitory effect on immune system and diminished production of this cytokine is associated with autoimmune disorders. objective: the aim of this study was to evaluate the influence of opium addiction on serum leve...

background: nowadays, the first step in treatment of ectopic pregnancy (ep) is medical treatment. medical treatment with methotrexate (mtx) for ep is safe and effective method without the risks associated with the surgical procedure. but there are controversies between studies for which patients will respond better to medical treatment. objective: the aim of the present study was to investigate...
