Growth and developmental effects of exposure to ammonium perchlorate during gestation, lactation, and post-lactation in deer mice
… the first litter were weaned at postnatal day (PND) 21 and dosing of the pups continued until PND 70, at which time they were necropsied. Pups from the second litter were necropsied for analysis at PND 21. Body weights in the 1 |iM group were significantly decreased at PND 5 and PND 20 in the …

IMPORTANCE OF THE D2 RECEPTOR FOR ONE- AND MULTI-TRIAL PSYCHOSTIMULANT-INDUCED BEHAVIORAL SENSITIZATION IN PREWEANLING RATS
… The pretreatment regimens occurred on either PND 16 or PND 20 (one-trial behavioral sensitization) or PND 13-16 or PND 17-20 (multi-trial behavioral sensitization). On PND 17 or PND 21, rats were challenged with either cocaine or methamphetamine and sensitized responding was assessed. With …

A comparison of attitudes towards prenatal diagnosis and pre-implantation genetic diagnosis
… out during pregnancy (prenatal diagnosis, PND). However, advances in technology have made it possible for diagnosis of an embryo created through in vitro fertilisation, prior to implantation into the womb (pre-implantation genetic diagnosis, PGD). This means that women can avoid the birth …

Ceramides as Therapeutic Targets in Bronchopulmonary Dysplasia
… to hyperoxia for 14 days (85% O₂ postnatal days [PND] 1-7 and 60% O₂ PND 7-14) followed by intermittent hypoxia from PND 14-21 (termed the HIH BPD-like lung injury model). Lung injury in this model was characterized by hypoplastic pulmonary vasculature, pulmonary hypertension, and "emphysematous" …

An investigation into how first generation Nigerian mothers living in the UK experience postnatal depression: an interpretative phenomenological analysis
… mothers’ experiences of Postnatal Depression (PND), there has been no research to date that has exclusively investigated the ‘lived’ experiences of the First Generation Nigerian Mothers (FGNMs) in relation to PND. This study is the first to investigate FGNMs’ postnatal depression experience in …

Neonatal Phencyclidine (PCP) induced deficits in rats: A behavioural investigation of relevance to schizophrenia.
… treated with neonatal PCP on postnatal days (PNDs) 7,9 and 11 or vehicle, followed by weaning on PND 21-22. The rats were then tested in behavioural paradigms such as novel object recognition, spatial memory and social interaction in their adolescent and adult stages and were also tested with …

Immunotoxicological Evaluation Of Critical Windows Of Development Following Exposure to 1,2:5,6 Dibenzanthracene in B6C3F1 Mice
… tested when evaluated at weaning, postnatal day (PND) 21, or when evaluated at sexual maturity (PND 42). Transference of DBA metabolites from mother to pup is suggested by HPLC analysis of milk extracted from PND 8 pups. In contrast, juvenile mice administered DBA beginning on PND 21 at dose …

Changes in Hippocampal Plasticity and HPA Axis Function Following Postnatal Exposure to Di(2-Ethylhexyl) Phthalate in Rats
… DEHP was injected in juvenile rats daily from PND 16 – PND 22. Brain tissue samples were analyzed by immunohistochemistry to quantify developing neurons. The Golgi – Cox Impregnation method was used for detailed morphological analyses. Blood samples were analyzed for corticosterone levels. The …

A study of the antimalarial action of Pyronaridine and its accumulation into Plasmodium falciparum
Pyronaridine (PND), a hydroxyanilino-benzonaphthyridine derivative and also a structural analogue of chloroquine, was synthesized in China in the 1970s as a result of a search for alternative drugs to treat chloroquine-resistant (CQR) Plasmodium falciparum malaria.
