to assess the relative contribution of genetic and environmental factors (particularly androgens) on circulating levels of lipid fractions, serum androgen and lipid fractions were measured in 34 pairs of female-female twins aged from 15- 45 years, some of whom were discordant for polycystic ovary syndrome (pcos) diagnosed by ultrasound. nineteen pairs were monozygotic twins (mz) and 15 pairs we...

the present report aimed to study an uncommon case of a pair of twins that presented a discordant dental phenotype. family investigation, clinical, radiographic examination and molecular analysis were performed in both girls. molecular analysis confirmed the monozygosity by deoxyribonucleic acid chip technology. one twin presented tooth agenesis in left upper lateral incisor and peg-shaped on t...

OBJECTIVES To determine the haemoglobin (Hb) differences at birth in monochorionic (MC) twins without chronic twin-to-twin transfusion syndrome (TTTS) in relation to birth order and placental vascular anatomy. METHODS All consecutive cases of MC twins without chronic TTTS and dichorionic (DC) twins delivered at our centre and admitted to our neonatal nursery between June 2002 and December 200...

A study of the discriminability of f ingerprints of twins is presented. The f ingerprint data used is of high quality and quantity because of a predominantly young subject population of 298 pairs of twins whose tenprints were captured using a livescan device. Discriminability using level 1 and level 2 features is independently reported. The level 1 study was to visually classify by humans each ...
