In the title compound, C(31)H(29)BrN(2)O(2)S, the pyrrolidine ring is in a twist conformation and the tetra-hydro-pyridine ring adopts an envelope conformation with the methine C atom adjacent to the NH group as the flap atom; the two rings are trans-fused. The bromo-benzene ring and the nearest phenyl ring form a dihedral angle of 82.72 (10)°. The benzyl phenyl and the tosyl phenyl rings are o...

The adult proximal tubule is a low-resistance epithelium where there are high rates of both active transcellular and passive paracellular NaCl transport. We have previously demonstrated that the neonatal rabbit and rat proximal tubule have substantively different passive paracellular transport properties than the adult proximal tubule, which results in a maturational change in the paracellular ...

A transgenic mouse line, PyLMP.5, exhibited a sex-linked lethality not observed in any other lines expressing the transgene. In this unique line, the transgene integrated into the X chromosome, yielding a simple tandem duplication of the insert sequences with minimal, if any, additional rearrangement of the cellular sequences. The predominant phenotype was a cleft secondary palate and neonatal ...

Mitochondria are key contributors to many forms of cell death including those resulting from neonatal hypoxic-ischemic brain injury. Mice have become increasingly popular in studies of brain injury, but there are few reports evaluating mitochondrial isolation procedures for the neonatal mouse brain. Using evaluation of respiratory activity, marker enzymes, western blotting and electron microsco...

Cardiac fibroblasts, myocytes, endothelial cells, and vascular smooth muscle cells are the major cellular constituents of the heart. The aim of this study was to observe alterations in myocardial cell populations during early neonatal development in the adult animal and to observe any variations of the cardiac cell populations in different species, specifically, the rat and mouse. Whole hearts ...

Prader-Willi syndrome (PWS) is a multisystem disorder caused by genetic loss of function of a cluster of imprinted, paternally expressed genes. Neonatal failure to thrive in PWS is followed by childhood-onset hyperphagia and obesity among other endocrine and behavioral abnormalities. PWS is typically assumed to be caused by an unknown hypothalamic-pituitary dysfunction, but the underlying patho...

The numbers of ultraviolet light (UV)-induced pyrimidine dimers in the DNA of neonatal BALB/c mouse skin were measured by assessing the sensitivity of the DNA to Micrococcus luteus UV endonuclease. Irradiation of neonatal BALB/c mice with FS40 sunlamps caused a dose-dependent induction of endonuclease-sensitive sites (pyrimidine dimers) in DNA extracted from back skin. Exposure of these UV-irra...

The symptoms of opiate withdrawal in infants are defined as neonatal abstinence syndrome (NAS). NAS is a significant cause of morbidity in term and preterm infants. Factors, such as polysubstance abuse, inadequate prenatal care, nutritional deprivation, and the biology of the developing central nervous system contribute to the challenge of evaluating and treating opiate-induced alterations in t...

objective: this study presents a simple method for isolation, expansion and purification of neonatal mouse spermatogonial stem cells. methods: we used enzymatic digestion to isolate a cell suspension of spermatogonia and sertoli cells from neonatal 2-day-old mice. the cells were cultured in dmem/f12 that contained 10% serum for two weeks. sertoli and spermatogonia cell characteristics were conf...
