Functional messenger RNA for human hemoglobin synthesis was prepared from reticulocyte lysates of patients with homozygous beta thalassemia and sickle cell anemia. The messenger RNA stimulated the synthesis of human globin chains by a cell-free system derived from Krebs mouse ascites cells. In the presence of beta thalassemia messenger RNA, the system synthesized much less beta chain than alpha...

The frequent occurrence of hyposthenuria in patients with sickle cell anemia has been noted since 1928 (1). McCrory, Goren, and Cornfeld (2), and Kunz, Pratt, Mellin, and Cheung (3), established that the urinary concentration defect was not due to a deficiency of the antidiuretic hormone and Zarafonetis, Steiger, Molthan, McMaster, and Colville (4), reported that subjects with the sickle cell t...

In the Democratic Republic of Congo, the incidence of sickle cell anemia (SCA) is estimated to affect 30,000 to 40,000 neonates per year. However, there is paucity of data on acute clinical manifestations in sickle cell children. In these circumstances, it is difficult to develop a health care policy for an adequate management of sickle cell patients. This was a seven years' retrospective study...

Sickle cell anemia is serious condition. People who have the disease when get infected with Covid-19 are more likely to suffer complications. In this paper, we report prevalence of complications sickle cells children covid-19 virus. As pathogen detection campaigns gotten prevalent, number patients diagnosed COVID19 has increased substantially. The majority moderate symptoms; most common clinica...

Sickle cell anemia is a genetically inherited disease in which the "SS" individual possesses an abnormal beta globin gene. A single base substitution in the gene encoding the human β -globin subunit results in replacement of β 6 glutamic acid by valine, leading to the devastating clinical manifestations of sickle cell disease. This substitution causes drastic reduction in the solubility of sick...

We studied the role of the sodium-potassium pump in erythrocytes of 12 patients with sickle cell anemia (SS). Ouabain-binding sites per cell and pump-mediated Rb/K uptake were significantly higher in SS patients than in white or black controls. Ouabainresistant Rb/K influx was also greater than in normal controls or patients with sickle cell trait. Deoxygenation of SS erythrocytes increased oua...

BACKGROUND Sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. The purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. METHODS A cross-sectional study was conducted among the sickle cell patients atten...

Sickle cell anemia results from a single amino acid substitution in the gene encoding the β-globin subunit. Polymerization of deoxygenated sickle hemoglobin leads to decreased deformability of red blood cells. Hashimoto's thyroiditis is a common thyroid disease now recognized as an auto-immune thyroid disorder, it is usually thought to be haemolytic autoimmune anemia. We report the case of a 32...

The accepted importance of circulatory impairment to sickle cell anemia remains to be verified by in vivo experimentation. Intravital microscopy studies of blood flow in patients are limited to circulations that can be viewed noninvasively and are restricted from deliberate perturbations of the circulation. Further knowledge of sickle blood flow abnormalities has awaited an animal model of huma...
