ABSTRACT Background Familial clustering of testicular germ cell tumour (TGCT) is well‐established, whereas the risk of non‐testicular cancer among relatives remains inconsistent across studies. Objective To evaluate the overall and site‐specific cancer risk among first‐degree relatives and grandparents of TGCT patients compared to cancer‐free controls.

Application of intraoral scanner to identify monozygotic twins
Background DNA base identification is a proper and high specificity method. However, identification could be challenged in a situation where there is no database or the DNA sequence is almost identical, as in the case of monozygotic (MZ) twins.

Infection control in the brain and the eye
Abstract The Central Nervous System (CNS), comprising the brain and the eye, is considered to have a ‘privileged’ mechanism for dealing with immunological challenge (immune privilege, IP). CNS IP has been revealed through experiments using foreign protein antigens and cell and tissue alloantigens (grafts), but evidence for a role for IP in modulating ...

A COMPARATIVE STUDY ON NEUROMOTOR DEVELOPMENT IN TWINS [PDF]
Twins are a valuable source of observation, being considered a key instrument in scientific fields such as genetics, biology, or psychology. The literature suggests that the hereditary and environmental influences can be assessed by comparing twin ...

Do Parents Propagate Inequality Among Children? Evidence From Chinese and Swedish Twins
ABSTRACT Economists have long studied how parental behavior shapes within‐family inequality, yet empirical findings remain mixed. Using twins data from China and Sweden, we examine the predominant mechanisms reported in the literature. Parents in both countries invest similarly during childhood.

Simultaneous cloacogenic carcinoma in dizygotic twins [PDF]
Dizygotic twins developed cloacogenic carcinoma of the anus almost simultaneously. The patients, although separated from the time they were 20-years-old, had very similar life styles. There are several reports in the medical literature of synchronous tumors in mono and dizygotic twins.

Indirect genetic effects of siblings
Background Within‐family designs are increasingly used to decompose genotype–trait associations into direct and indirect genetic effects. Many such designs, including trio designs or within‐sibship designs, assume an absence of sibling indirect genetic effects.

A study of diabetes mellitus within a large sample of Australian twins. [PDF]
Udgivelsesdato: 2008-FebTwin studies of diabetes mellitus can help elucidate genetic and environmental factors in etiology and can provide valuable biological samples for testing functional hypotheses, for example using expression and methylation studies

Background Past studies indicate significant associations between birth anthropometrics, such as relative birthweight or head circumference, and later cognitive performance. Using twin data, we investigated whether these associations are confounded by genetic and environmental factors.
