Beta-thalassemia is one of the most common autosomal recessive disorders in the world population resulting from over 200 different mutations of HBB gene. Beta-thalassemias are caused by point mutations or, more rarely, deletions in the HBB gene leading to reduced (beta+) or absent (beta0) synthesis of the beta chains of hemoglobin (Hb). High-resolution melting of polymerase chain reaction (PCR)...

Most of the beta thalassaemia cases are heterogeneous at molecular level. The genetic variation arises due to mutation a single beta-globin gene (HBB) on chromosome 11p15.5. Eventhough, basis and natural history this disorder still not well understood clinical presentation in certain patients was always correlated with diagnosis [1].

Context. The formation of silicates in circumstellar envelopes stars evolving through the asymptotic giant branch (AGB) is still highly debated given uncertainties affecting stellar evolution modelling, description dust process, and capability silicate grains to accelerate outflows via radiation pressure. Aims. We study winds intermediate mass ( M ≥ 4 ⊙ ) solar metallicity while AGB phase. test...

Introduction: Single isocentre half-beam block (HBB) technique permits the avoidance of hot and cold spots. This technique is very useful in sparing the underlying ipsilateral lung and heart, if the left breast is treated. The major advantage of this technique is that it facilitates the complete sparing of both contralateral breast and lung. Regarding this, the present study aimed to analyse th...
