This study investigated the influence of genetic factor and personality on leadership role occupancy among a sample of male twins. Identical twins (n =238) who share 100% of their genetic background were compared with fraternal twins (n =188) who are expected to share only 50% of their genetic background. Results indicated that 30% of the variance in leadership role occupancy could be accounted...

Reliable and accurate veri!cation of people is extremely important in a number of business transactions as well as access to privileged information. Automatic veri!cation methods based on physical biometric characteristics such as !ngerprint or iris can provide positive veri!cation with a very high accuracy. However, the biometrics-based methods assume that the physical characteristics of an in...

The prevalence of temporal landmarks has been revealed in a wide range of tasks associated with autobiographical memory, such as recall and dating of personal events. The author examined 3 types of events that have usually been considered landmarks: flashbulb memories, 1st experiences, and reference points in personal histories. The differences between landmark events and nonlandmark events are...

We present unusual retained remnants of hidden conjoined twin of possible abdominal pagus after 21 years who presented with abdomenpain and incidentally have found his forbidden conjoined twin. He presented for many years with a palpable epigastric mass, and recent abdominal pain, early satiety, nausea and vomiting. The mass was a like deformed fetus weighing 815 gr who was anencephalic and dep...

OBJECTIVE We sought to review the natural history, pathophysiology, diagnosis, and treatment options for twin-twin transfusion syndrome (TTTS). METHODS A systematic review was performed using MEDLINE database, PubMed, EMBASE, and Cochrane Library. The search was restricted to English-language articles published from 1966 through July 2012. Priority was given to articles reporting original res...

Method: This study is further analysis of data in a case report of a dichorionic-dizygotic twin pregnancy in which one twin (Twin-A) presented three months postnatally with seizure. The other twin (Twin-B) developed normally and so became a control. The twins showed similar head growth up to 24 weeks but subsequently the rate of head growth of Twin-A exceeded that of Twin-B. Later, from 29 week...

in order to investigate deformation history preserved in the calcite twins in the hinterland of zagros, several samples have been collected from calcschists of the paleozoic sargaz complex in the faryab area, se iran. these samples are related to f1-recumbent folding and thrust shear zones. the twin width is about 1 and 3.8 µm (thin-twin regime); the twin strain amounts 5 and 10%; twin intensit...

a twin pregnancy with a coexisting complete hydatidiform mole and a healthy fetus (cmcf) is rare. here we report three cases of cmcf with different clinical courses but similar outcome without a surviving neonate. two women required uterine evacuation before 20 weeks of gestational age because of vaginal bleeding and medical complications and the other patient underwent termination of her pregn...
