SBA-15 grafted with N-(4-(trimethylsilyl) butyl)-9H-fluorene-9-amine was synthesized by a simplestrategy and applied to removal of Acid Red 33 and Acid Black 194 from aqueous solutions. SBA-15 was synthesized and Functionalized according to procedure in the literature. Fluorenefunctionalized SBA-15 was showed the BET surface area 200 m2g-1 and pore diameter 4.2 nm,based on adsorption-desorption...

We have studied the changes in amino acid transport in fetal erythroid cells isolated from rat fetal liver at different gestation days. Our results show that System A transport as measured by the Na+-dependent uptake of 2-(methylamino)isobutyric acid (MeAIB) was conspicuous at day 13 but virtually disappeared between days 16 and 18. In contrast, the activity of System ASC measured by the Na+-de...

OBJECTIVE To determine whether adipose and red blood cell membrane lipids, particularly long-chain polyunsaturated fatty acids such as docosahexaenoic acid and eicosapentaenoic acid, are significantly correlated with phenotype in a family with autosomal dominant Stargardt macular dystrophy (gene locus STGD3). A mutation in the ELOVL4 gene is responsible for the macular dystrophy in this family,...

In this work, removal of C. I. Acid Red 14 was investigated by Pumice stone as a low cost adsorbent. Various parameters such as initial dye solution, contact time and pH were studied. Removal of dye were increased by increasing of contact time and initial dye solution and deceased by increasing of pH. Three isotherm models were studied. Linear and non-linear regression analyses were used fo...

BACKGROUND Observational studies and clinical trials have shown conclusive evidence that periconceptional folic acid supplementation prevents up to 70 % of neural tube defects (NTD). The Honduran government wanted to implement a supplementation programme of folic acid but needed to assess the relative effects of two dosages of folic acid. OBJECTIVE To determine the effect of two dosages of fo...

BACKGROUND There is a high prevalence of blood product transfusions in orthopedic surgery. The reported prevalence of red blood cell transfusions in unselected patients undergoing hip or knee replacement varies between 21% and 70%. We determined current blood loss and transfusion prevalence in total hip and knee arthroplasty when tranexamic acid was used as a routine prophylaxis, and further in...

This study presented a mini review on folic acid deficiency and recommendations for its supplementation in thalassemia intermedia (TI). TI is a clinical condition which lies between thalassemia major and thalassemia minor. Although TI patients may not need regular blood transfusion, precise diagnosis and management are critical for the prevention of clinical complications and quality of life im...
