BACKGROUND The present study investigates the effects of Vitellaria paradoxa crude extract administration on Salmonella typhimurium infected Wistar rats. METHODS Rats were infected by single dose oral administration of Salmonella typhimurium (1.5×108 CFU). Negative control groups were infected and treated orally with distilled water (vehicle), neutral control group were not infected, while th...

In this study, adults with Parkinson's disease (PD) used virtual cueing spectacles (VCS) mimicking kinesia paradoxa in home and community settings to assess the impact on mobility and participation. We used an ABA single-subject design with repeated measures. Six adults with PD, akinesia, and stage III or IV Hoehn and Yahr rating scale status used VCS in their homes and communities for a week o...

Calcium signaling is one of the most extensively employed signal transduction mechanisms in life. As life evolved into increasingly complex organisms, Ca acquired more extensive and varied functions. Here, we compare genes encoding proteins that govern Ca entry and exit across cells or organelles within organisms of early eukaryotic evolution into fungi, plants, and animals. Recent phylogenomic...

Members of the three existing genera of lungfishes represent different stages in the transition from aquatic to aerial breathing. Neoceratodus, the Australian lungfish, is primarily aquatic and utilizes gill breathing, while its lung offers an accessory means for O2 absorption (Lenfant, Johansen & Grigg, 1966; Johansen, Lenfant & Grigg, 1967). Conversely, the South American lungfish, Lepidosire...

We report 1.87 lm photometry and astrometry of the inner satellites (Proteus, Larissa, Galatea, and Despina) and ring arcs of Neptune, obtained with the Hubble Space Telescope and its near-infrared camera NICMOS. From comparison with the Voyager data obtained at visible wavelengths, the small bodies orbiting within the ring region of Neptune have a near-infrared albedo consistently low, but hig...

This chapter presents an augmented-reality based therapeutic device designed to overcome gait problems associated with Parkinson's Disease (PD). A normal model of gait is proposed followed by a model of Parkinsonian gait with the goal of construction of a gait enabling therapeutic device. The fundamental underlying tenet of the model is that vision pathology is responsible for the majority of P...

The gene, rnpB, encoding the RNA portion of ribonuclease-P has been found in the cyanelle DNA of Cyanophora paradoxa. A secondary structure model for the cyanelle RNA fits into that for eubacterial Rapb-RNAs.

The full nucleotide sequences of DNA ribosome cluster of Leucochloridium paradoxum Carus, 1835 and L. perturbatum Pojmanska, 1967 were obtained. rDNA was extracted from 40 isolates of Leucochloridium sp. and analyzed using specific primers. The intraspecific genetically identity of morphologically detected L. paradoxum and L. perturbatum sporocysts was proven. A noticeable interspecific diverge...

Cognitive theories of analogical problem solving typically use representations of structural and causal content. But imagery and visual knowledge too can play an important role in analogy, problem solving, and cognition in general. This study presents Galatea, an operational computational model of analogical transfer that can solve Duncker’s “radiation problem” (1926) using only imagistic knowl...
