OBJECTIVES We studied the association of diabetes transmission with left ventricular hypertrophy (LVH) in patients with non-insulin-dependent diabetes mellitus (NIDDM). BACKGROUND It is suggested that NIDDM has a strong genetic basis and that maternally transmitted NIDDM is associated with mitochondrial deoxyribonucleic acid (DNA) mutations. However, genetic factors for LVH in NIDDM are unkno...

Paternal care is rare among mammals, occurring in ≈6% of species. California mice (Peromyscus californicus) are unusual; fathers participate extensively in raising their young and display the same components of parental care as mothers, with the exception of nursing. Parenting is a complex experience, having stressful and enriching aspects. The hippocampus is sensitive to experience and respond...

OBJECTIVES To determine whether the offspring of cancer survivors are at an increased risk of congenital anomalies and whether cancer therapy before conception is associated with such an increase. DESIGN Case-control study using computerised record linkage. SETTING Ontario, Canada. SUBJECTS Parents of children born during April 1979 to December 1986 who had a congenital anomaly diagnosed ...

Testosterone (T) is thought to help facilitate trade-offs between mating and parenting in humans. Across diverse cultural settings married men and fathers have lower T than other men and couples' sexual activity often declines during the first years of marriage and after having children. It is unknown whether these behavioral and hormonal changes are related. Here we use longitudinal data from ...

In the 1890s, one of Charcot's most important protégés, Dr. Paul Richer (1849-1933), drew and sculpted a series of representations of the main types of nerve pathology. That series included drawings of pleomorphic hysterical crises and sculptures depicting patients suffering from labio-glosso-laryngeal paralysis and myopathy, as well as Parkinson's disease. Richer was a resident at La Salpêtriè...

BACKGROUND The transition to parenthood is consistently associated with declines in physical activity. In particular, working parents are at risk for inactivity, but research exploring physical activity barriers and facilitators in this population has been scarce. The purpose of this study was to qualitatively examine perceptions of physical activity among working parents. METHODS Working mot...

BACKGROUND Embryo donation produces a family structure where neither rearing parent is genetically related to the child, as in adoption. It is not known how embryo donation parents view the donors compared with how adoptive parents view the birth parents. METHODS 21 couples with an embryo donation child aged 2-5 years were compared with 28 couples with an adopted child. Parents were administe...
