BACKGROUND Congenital rib abnormalities are found in approximately 2% of the general population. Usually, they occur in isolation, when they are rarely symptomatic, but they can also associate with other malformations. MATERIALS AND METHODS We reviewed imaging examinations performed over a period of two years (2014-2015), enabling us to identify isolated rib abnormalities in six adult patient...

Diced rib cartilage is an acceptable option in severe nasal deformities. We present our preliminary experience in KAMC in nasal septoplasties using the autologous diced costal cartilage. This is a retrospective study of the 22 cases who needed the autologous diced costal cartilage in our centre in 4 years. All our patients needed autologous diced rib cartilages. Twelve were wrapped with tempora...

Background: Children affected with sickle cell disease (SCD) are at increased risk for severe morbidity and mortality, especially during the first 3-5 years of life. It is suggested that early treatment can improve the condition. The aim of this pilot study was to estimate the incidence of hemoglobin S (HbS) by umbilical cord blood screening in Khorramshahr and Abadan cities in southwest of Ira...

Sickle cell disease is an autosomal recessive hematological disorder resulting from a missense point mutation in the beta chain of haemoglobin molecule. This article reports case homozygous sickle adult patient with long-standing history non-healing ulcer

As the GDL (Gas diffusion layer) is most sensitive component in fuel cell, any change its structure causes a porosity, which strongly influences contact between components of cell. Note that state depends on applied clamping pressure, thickness and porosity GDL, geometry rib (bending radius) BPP (Bipolar plates). These can be subject to variations coming from very high compression, so it necess...

We present in this paper two novel concepts of hybrid metamaterials that combine a core unit cell re-entrant or cross-chiral shape and lateral missing ribs. The first topology is between an anti-tetrachiral rib (cross-chiral) configuration; the second one has variable layout compared to classical square structure. Their in-plane mechanical properties have been investigated from parametric point...

Sickle cell disease affects more than 100,000 individuals in the United States, among whom disease severity varies considerably. One factor that influences disease severity is the sickle cell disease genotype. For this reason, clinical prevention and treatment guidelines tend to differentiate between genotypes. However, previous research suggests caution when using a claimsbased determination o...

The R28 protein of group A streptococcus (GAS) and the Rib protein of group B streptococcus (GBS) are surface molecules that elicit protective immunity to experimental infection. These proteins are members of the same family and cross-react immunologically. In spite of extensive amino acid residue identity, the cross-reactivity between R28 and Rib was found to be limited, as shown by analysis w...

BACKGROUND Right thoracic curvature, rib cage deformities and aortic left shift are features of adolescent idiopathic scoliosis that are correlated with each other. We recently reported that disturbance of ribcage development results in progressive thoracic scoliosis in mice. Recently, it has been confirmed that the normal spine exhibits right thoracic curvature and rib cage deformities and tha...

Micropipette aspiration tests on single erythrocytes have previously shown that the static rigidity (membrane shear modulus) of oxygenated sickle cells increased with increasing hemoglobin concentration, whereas the rigidity of normal cells was independent of hemoglobin concentration. Moreover, it was observed that after mechanical extension, sickle cells exhibited persistent deformation more f...
