this article presents the application of two algorithms: heuristic big bang-big crunch (hbb-bc) and a heuristic particle swarm ant colony optimization (hpsaco) to discrete optimization of reinforced concrete planar frames subject to combinations of gravity and lateral loads based on aci 318-08 code. the objective function is the total cost of the frame which includes the cost of concrete, formw...
beta thalassemia is the most common autosomal recessive disorder. the present study reports a rare β globin gene mutation, hbb: c.180g>a: codon 59 (aag/aaa), in a patient from gilan province, northern iran. nucleotide sequencing of amplified dna belonging to a 35 years old man presenting mild hypochromia revealed a synonymous mutation due to a g>a conversion at the third position of codon 59 o...
ABSTRACT We study a sample of single Galactic post-asymptotic giant branch (post-AGB) stars with known surface chemical composition. Gaia EDR3 and DR3 parallaxes have enabled accurate determinations the luminosities these objects, thus making it possible to characterize them in terms their initial masses, compositions, progenitor ages. used extant evolutionary sequences asymptotic (AGB) produce...
We present the results of extensive computation of the Thermal Pulse phase AGB evolution of stars of metallicities in mass fraction 2 10 ?4 Z 0:01, for those masses in the range 2:5 M=M 6, which suuer the Hot Bottom Burning (HBB) phase. The evolution is fully computed, by assuming a mass loss rate consistent with the observations of the Magellanic Clouds lithium rich stars, and modelling convec...
Bệnh Thalassemia là bệnh di truyền phổ biến nhất trên thế giới. Ước tính tỷ lệ mang gen thalassemia trung bình trong cộng đồng tất cả các dân tộc Việt Nam 13,8%. β-thalassemia thể nặng có biểu hiện thiếu máu tan nặng, ảnh hưởng đến khả năng sống, chất lượng sống của người bệnh. Việc sàng lọc, chẩn đoán sớm bệnh, đóng vai trò quan trọng giúp hạn chế sinh ra trẻ mắc β-thalassemia. Nhiều kỹ thuật ...
Background: Hemoglobin is the major protein found in erythrocytes, where it acts as an oxygen carrier molecule. In recent years, its expression has been reported also in neurons and glial cells, although its role in brain tissue remains still unknown. Altered hemoglobin expression has been associated with various neurodegenerative disorders. Here, we investigated hemoglobin mRNA levels in brain...
Codon 104(-G), a heterozygous frameshift mutation in exon 2 of HBB, resulted in a dominantly inherited beta0-phenotype with mild anemia in a German kindred, and thalassemia intermedia in the index patient. A co-inherited a gene triplication, long-term transfusion therapy, and ineffective erythropoiesis were confounding factors.
