Extreme longevity requires the continuous and large-scale adaptation of organ systems to delay senescence. Naked mole rats are the longest-living rodents, whose nervous system likely undergoes life-long adaptive reorganization. Nevertheless, neither the cellular organization of their cerebral cortex nor indices of structural neuronal plasticity along extreme time-scales have been established. W...

An 18-month-old proposita with psychomotor retardation and other congenital abnormalities is presented. Chromosomal analysis of both parents proved normal. However, the karyotype of the proposita contained 47 chromosomes in both lymphocytes and cultured fibroblasts. The marker chromosome proved to be a deleted No. 14 or 15. Comparison of the reported cases of partial trisomy D indicates that a ...

BACKGROUND Vascular depression is regarded as a subtype of depression, especially in, but not entirely restricted to, the elderly, characterized by a specific clinical presentation and an association with (cerebro)vascular risk and disease. It could have major implications for treatment if subjects at risk for such a depression could be easily identified by their clinical presentation in genera...

Gravity represents a stable reference for the nervous system. When the individual is increasing in size and weight, gravity may influence several aspects of the sensory and motor developments. To clarify this role, we studied age-dependent modifications of several exteroceptive and proprioceptive reflexes in five groups of rats conceived, born and reared in hypergravity (2 g). Rats were transfe...

Depression and dementia are common in older people and their association is very complex. Major and minor depression occur often in patients with dementia and can be associated with deterioration in cognitive functioning. Many clinicians have difficulty determining whether dementia, depression or both are the underlying disease for their patients' apathy, psychomotor retardation, concentration ...

Invasive species that penetrate habitat boundaries are likely to experience strong selection and rapid evolution. This study documents evolutionary shifts in tolerance and performance following the invasion of fresh water by the predominantly estuarine and salt marsh copepod Eurytemora affinis. Common-garden experiments were performed on freshwater-invading (Lake Michigan) and ancestral saline ...

A sixteen year-old male patient with no history of consanguinity in the family, reported with patchy, thickened lichenified plaques over the whole body. Some areas had normal skin while some were Blaschkoid lesions. The child had delayed milestones along with hypogonadism. Digital contracture with palmoplantar keratoderma was present. Histopathology showed characteristic vacuolar degeneration o...

OBJECTIVES To assess the seizure and developmental outcome in children with West syndrome with respect to treatment lag. METHODS Twenty-six children satisfying inclusion criteria of West syndrome i.e., infantile spasms, psychomotor retardation and abnormal EEG pattern were prospectively evaluated. Response to treatment was assessed based on seizure control, EEG, developmental assessment and p...
