The Effect of p.Arg25Cys Alteration in NKX2-5 on Conotruncal Heart Anomalies: Mutation or Polymorphism?
Heterozygous mutations in the NKX2-5 gene of patients with various congenital heart defects have been reported. Most of the congenital heart defects associated with the mutations in the NKX2-5 gene are conotruncal heart anomalies, primarily the tetralogy of Fallot. In this study, the authors screened 72 Turkish children with conotruncal heart anomalies and 185 healthy control subjects to find the NKX2-5 alterations. They found one previously documented NKX2-5 missense alteration, heterozygous c.73C>T (p.Arg25Cys), in a 10-year-old boy with tetralogy of Fallot. The same heterozygous alteration was found also in the patient’s healthy father and in two unrelated persons in the healthy control group. The current study shows for the first time the presence of p.Arg25Cys in healthy control subjects other than African Americans. These results show that no genetic support exists for the pathogenecity of this alteration, although a previous in vitro study and theoretical predictions suggest a structural/functional difference in the altered protein region

Influência do local de ancoragem dos implantes na vértebra sobre o torque de inserção e resistência ao arrancamento Influencia de la ubicación de los implantes en la vértebra cuanto al torque de inserción y resistencia de arrancamiento Influence of anatomical vertebral site on screw insertion torque and pull-out strength
OBJETIVO: Avaliar a influência do sítio anatômico da ancoragem dos implantes na vértebra sobre a resistência ao arrancamento e o torque de inserção dos parafusos pediculares com alma cônica e cilíndrica. MÉTODOS: Parafusos cilíndricos e com alma cônica foram inseridos no pedículo e corpo vertebral de 10 vértebras lombares (L4-L5) de vitelos. Foram avaliados o torque de inserção e a resistência ao arrancamento dos parafusos inseridos no corpo e no pedículo vertebral. RESULTADOS: Os valores do torque de inserção e resistência ao arrancamento foram maiores nos parafusos de alma cilíndrica e alma cônica inseridos no pedículo vertebral. CONCLUSÕES: A ancoragem dos implantes no pedículo vertebral apresentou maiores valores do torque de inserção e da força de arrancamento que os implantes inseridos no corpo vertebral nos dois tipos de parafusos utilizados.<br>OBJETIVO: Evaluar la influencia de la localización anatómica de la fijación de los implantes en la vértebra cuanto al torque de inserción y resistencia de arrancamiento de los tornillos con alma cónica y cilíndrica. MÉTODOS: Los tornillos con alma cilíndrica y cónica se insertan en el cuerpo y el pedículo vertebral de diez vértebras lumbares (L4-L5) de los terneros. Se evaluó el torque de inserción y resistencia al arrancamiento de tornillos insertados en el cuerpo y el pedículo. RESULTADOS: El torque de inserción y resistencia al arrancamiento fue mayor para los tornillos con alma cónica y cilíndrica insertados en el pedículo. CONCLUSIONES: La fijación de los implantes en el pedículo mostró mayor torque de inserción y resistencia al arrancamiento en comparación con los implantes en el cuerpo vertebral, en ambos tipos de tornillos.<br>OBJECTIVE: To evaluate the influence of anatomical site of implants on vertebra about insertion torque and pull-out strength of conical and cylindrical core screws. METHODS: Conical and cylindrical core screws were inserted into the pedicle and vertebral body of 10 lumbar vertebrae (L4-L5) of calves. In the study were evaluated insertion torque and pull-out strength of screws inserted into the body and pedicle. RESULTS: The insertion torque and pull-out strength were higher for conical and cylindrical core screws inserted into vertebral pedicle. CONCLUSIONS: The anchoring of implants into the pedicle showed higher insertion torque and pull-out strength than implants inserted into the vertebral body in both types of screws used
