BACKGROUND Postnatal depression is a recognised cause of delayed cognitive development in infants in developed countries. Being underweight is common in South Asia. AIMS To determine whether postnatal depression contributes to poor growth and development outcomes in Goa, India. METHODS Cohort study for growth outcomes with nested case-control study for developmental outcomes. A total of 171...

AIM To study the expression pattern of the retinoic acid metabolizing enzymes RALDH2 and CYP26b1 during mouse postnatal testis development at both mRNA and protein levels. METHODS Real-time polymerase chain reaction and Western blot analysis were performed to determine the relative quantity of RALDH2 and CYP26b1 at both mRNA and protein levels at postnatal day 1, 5, 10, 20, and in adult mice ...

We investigated the electrophysiological and morphological characteristics of the neurons in the ventral partition of medial geniculate body (MGBv) in the rat during postnatal development (postnatal day 3-30, P3-30) with whole-cell patch clamp recording and intracellular labeling technique. The results are as follows: (1) There was an increase in the negativity of the resting membrane potential...

BACKGROUND Studies have often compared the postnatal motor development of 'small' versus 'normal' newborns. Not much is known about the associations between a broad spectrum of size at birth and motor development. The effect of early postnatal growth on motor development is little researched. Growth failure in terms of shortness and thinness should be differentiated, but not many studies have t...

aims: intellectual disability is a condition characterised by the inability of a person to undertake normal psychological activities. the purpose of this study was to systematically review the intellectual disability in children and discuss the implications of different environmental and genetic factors, which describe particular categories of intellectual disable cases. information & methods: ...

Maternal exposure to polystyrene nanoplastics impact postnatal brain development in mouse offspring. This work motivates further studies determine the levels of environment.

Kölliker's organ is a temporary but indispensable structure in the development of the cochlea. Supporting cells (SCs) within it release adenosine 5'-triphosphate (ATP), which may play a crucial role in cochlear development before the onset of hearing. To reveal the apoptosis of Kölliker's organ in new-born rats, we studied the morphological changes and expression of apoptosis-related factors du...

The expression level of phospholipase D (PLD) was examined in the lungs of mice during postnatal development. Immunoprecipitation analysis revealed a moderate basal level of PLD1 in the lungs at postnatal 1 week, with a gradual increase occurring until week 4. The pattern of PLD2 paralleled that of PLD1, although the quantity of PLD2 was markedly less. PLD was immunostained in the most bronchio...

Although the brain continues developing in the postnatal period, epidemiological studies on the effects of postnatal exposure to neurotoxic POPs through breast-feeding remain mostly inconclusive. Failure to detect associations between postnatal exposure and health outcomes may stem from the limitations of commonly employed approaches to assess lactational exposure. The aim of the present study ...
