The unexplained sunward acceleration aP of the Pioneer 10 (P10) and the Pioneer 11 (P11) spacecraft remains a mystery. A scalar potential model (SPM) that derived from considerations of galaxy clusters, of red-shift, and of HI rotation curves of spiral galaxies is applied to the Pioneer Anomaly. Matter is posited to warp the scalar potential ρ field. The changing ρ field along the light path ca...

Occasionally, multiple names are given to the same gene/protein. When this happens, different names can be used in subsequent publications, for example in different research areas, sometimes with little or no awareness that the same entity known under a different name may have a major role in another field of science. Recent reports about the protein p11 presented findings that this protein, co...

Developmental exposure to manganese (Mn) or stress can each be detrimental to brain development. Here, Sprague-Dawley rats were exposed to two housing conditions and Mn from postnatal day (P)4-28. Within each litter two males and 2 females were assigned to the following groups: 0 (vehicle), 50, or 100 mg/kg Mn by oral gavage every other day. Half the litters were reared in cages with standard b...

Aim of this study was to examine synaptic connectivity changes in the retina and the location and rate of apoptosis in transgenic S334ter line-3 and line-5 rats with photoreceptor degeneration. Heterozygous S334ter-line-3 and line-5 at P11-13, P30, P60, P90 and several control non-dystrophic rats (Long Evans and Sprague-Dawley) at P60, were studied anatomically by immunohistochemistry for vario...

The role of brain stem serotonin (5-hydroxytryptamine, 5-HT) in autoresuscitation in neonatal life is unclear. We hypothesized that a specific loss of 5-HT would compromise gasping and autoresuscitation mainly in the second postnatal week and that acute restoration of 5-HT would reverse the defects. We exposed postnatal day (P)4-5, P8-9, and P11-12 tryptophan-hydroxylase-2 knockout (TPH2(-/-)) ...

BACKGROUND AND PURPOSE Low level of thyroid hormone is a strong independent risk factor for white matter (WM) injury, a major cause of cerebral palsy, in preterm infants. Thyroxin upregulates brain-derived neurotrophic factor during development. We hypothesized that thyroxin protected against preoligodendrocyte apoptosis and WM injury in the immature brain via upregulation of brain-derived neur...

Primary gastric synovial sarcoma is rare and challenging to diagnose. We present a case of ulcer that was diagnosed as primary only after surveillance endoscopy with repeat biopsies. The diagnosis established the identification pathognomonic chromosomal translocation t(X;18)(p11;q11). patient treated wedge resection has remained disease-free on imaging endoscopy. This demonstrates difficulty in...
