We studied the dynamical influence of a dust component on the gaseous phase in central regions of galactic disks. Therefore, we performed two-dimensional hydrodynamical simulations for flat multi-component disks embedded in a stellar and dark matter potential. The pressure-free dust component is coupled to the gas by a drag force depending on their velocity difference. It turned out that the mo...

During the last three decades progress in mapping the universe from an age of 400,000 years to the present has been stunning. Instrument/telescope combinations have naturally determined the sampling of various redshift ranges. Here we outline the impact of the Hectospec on the MMT on exploration of the universe in the redshift range 0.2 . z . 0.8. We focus on dense redshift surveys, SHELS and H...

Where is the long–awaited one? A supersymmetric neutralino has been a favored candidate for the WIMP dark matter but, so far, it has not been found. One way to locate it is to identify where it can be hiding in the vast supersymmetric parameter space. A combination of theoretical, experimental and cosmological constraints leads to remarkably well–defined allowed regions which favor lighter neut...

In a new survey of nearby galaxies from stacked photographic images, seemingly regular galaxies of several types show amorphous, often asymmetrical features at very faint levels (28mag arcsec). In M87, a diffuse fan of stellar material extends along the projected SE (major) axis out to about 100 kpc. We suggest that accretion of a small spheroidal galaxy into a larger potential is the most like...

Rhabdomyolysis is a rare condition caused by the proteins of damaged muscle cells entering the bloodstream and damaging the kidneys. Common symptoms of rhabdomyolysis are muscle pain and fatigue in conjunction with dark urine; kidney damage is a common symptom among these patients. We present a case of a 23-year-old woman who displayed myalgia in the upper extremities caused by low-intensity an...

Djungarian hamsters ( Phodopus sungorus) acclimated to a short photoperiod (8:16-h light-dark cycle) display spontaneous daily torpor with ad libitum food availability. The time course of body temperature (Tb), metabolic rate, respiratory quotient (RQ), and substrate and enzyme changes was measured during entrance into torpor and in deep torpor. RQ, blood glucose, and serum lipids are high duri...

Rhabdomyolysis is a process of muscle destruction that can present with varying clinical manifestations. In pediatric patients, its main etiology is infectious diseases. We present a previously healthy adolescent who was admitted to our emergency department with a four-day history of myalgia, muscle weakness and dark urine. At presentation, she was dehydrated. Blood analysis revealed acute rena...

A five-year-old male cynomolgus monkey (Macaca fascicularis) with loose stool from two days before dying was observed with dark blood-like watery diarrhea. The animal was not used in the toxicology study as its body weight (4.5 kg) was lower than that of male monkeys of the same age. Gross examination revealed a clockwise rotation of the colon accompanied by a dark-reddish change and distention...

Small temperate birds reversibly modify their aerobic performance to maintain thermoregulatory homeostasis under seasonally changing environmental conditions and these physiological adjustments may be attributable to changes in the expression of genes in the underlying regulatory networks. Here, we report the results of an experimental procedure designed to gain insight into the fundamental mec...
