BACKGROUND The clinical conditions of various diseases, including coronary artery disease, are determined by genetics and the environment. Previous investigations noted the significance of genetic mutations and polymorphisms in cases of coronary spasm. CASE REPORT We report on monozygotic identical twins who almost simultaneously presented with vasospastic angina. The 58-year-old younger twin...

Case 1 A 25-year-old nurse presented in September 1977 with a four-week history of sustained pyrexia, rigors, anorexia, weight loss, non-productive cough, and pleuritic chest pain. Since the age of 16 she had noticed transient mild wheeziness, associated with hay fever during the summer months. Wheezing had become episodic and more severe during her present illness, and she was taking salbutamo...

This is a report of the successful kidney transplantation from one identical twin to another with good renal function persisting after 9 months. Previous attempts at renal homotransplantation both clinically and experimentally had been unsuccessful, with the one exception between di-zygotic bovine twins in which a kidney transplant has survived and functioned for over a year. Success in that in...

Female twins concordant for thanatophoric dysplasia are presented. Monozygosity was confirmed using minisatellite DNA genetic fingerprinting. The evidence supporting new dominant mutations as the likely cause of thanatophoric dysplasia is reviewed.

A pair of identical twins both of whom died of subarachnoid haemorrhage from ruptured anterior communicating artery aneurysms are reported. These twins are compared to the three other reported twins with ruptured cerebral aneurysms.

Biometric recognition based on human characteristics for personal identification has attracted great attention. The performance of biometric systems highly depends on the distinctive information in the biometrics. However, identical twins having the closest geneticsbased relationship are expected to have maximum similarity between their biometrics. Classifying identical twins is a challenging p...

Identical twins pose a great challenge to face recognition systems due to their similar appearance. Nevertheless, even though twins may look alike, we believe they speak differently. Hence we propose to use their voice patterns to distinguish between twins. Voice is a natural signal to produce, and it is a combination of physiological and behavioral biometrics, therefore it is suitable for twin...
