Abstract study objectives: sleep problems are a common phenomenon in most neurological and psychiatric diseases. In parkinson disease (pd), for instance, sleep problems may be the most common and burdensome non-motor symptoms in addition to the well-described classical motor symptoms. cheap generic viagra Since sleep disturbances generally become apparent in the disease before motor symptoms emerge, they may represent early diagnostic tools and a means to investigate early mechanisms in pd onset. The sleep disturbance, rem sleep behavior disorder (rbd), precedes pd in one-third of patients. cheap viagra online We therefore investigated sleep changes in marmoset monkeys treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (mptp), the non-human primate model for idiopathic pd. there generic viagra united states Design: mild parkinsonism was induced in 5 marmoset monkeys (3m/2f) over a 2-week period of subchronic mptp treatment. Electroencephalograms (eegs) and electromyograms (emgs) were recorded weekly. Motor activity and hand-eye coordination were also measured weekly, and any signs of parkinsonism were noted each day. Sleep parameters, motor activity, and performance data before and after mptp treatment were compared between mptp-treated marmosets and 4 control marmosets (1m/3f). generic viagra sales Results: mptp increased the number of sleep epochs with high-amplitude emg bouts during rem sleep relative to control animals (mean â± sem percentage of rem 58. 2 â± 9. 3 vs. how to buy generic viagra 29. 6 â± 7. viagra soft tabs canada 7; p < 0. 05). Of all sleep parameters measured, rbd-like measures discriminated best between mptp-treated and control animals. real viagra without a prescription On the other hand, functional motor behavior, as measured by hand-eye coordination, was not affected by mptp treatment (correct trials mptp: 23. viagra online 40 â± 3. 56 vs. viagra effect on refractory period Control: 36. 13 â± 5.

Viagra viagra en viagra Conclusions: this rem sleep-specific change, in the absence of profound changes in wake motor behaviors, suggests that the mptp marmoset model of pd could be used for further studies into the mechanisms and treatment of rbd and other sleep disorders in premotor symptom pd.

Penn State University Study


“A Study on the Effect of Nan-O-Sil ASD on Cooling Time Reduction” was undertaken by Jonathan Meckley, Pennsylvania State University at Erie, The Behrend College , Erie, PA (see technical paper 1) that will be presented at ANTEC in May 2010, that demonstrated the Nan-O-Sil ASD additive can reduce cycle time by as much as 70% in semi-crystalline materials.

In PP the cooling time was reduced 77%.

In glass filled PBT, it is 70%.

Glass-filled Nylon has a 67% reduction without negative physical properties.

Nan-O-Sil ASD


A unique colloidal silica processing aid from Energy Strategy Associates, Inc. slashes molding cycle times. Ultra-fine bright white silica particles have been shown in laboratory and commercial field trials to reduce injection molding cycle times by 20% to 30% in polypropylene, filled and unfilled nylon, PBT, Acetal, glass filled PC, PPS, PEEK, and Rigid PVC (read more: PVC Results Summary | Nanosil ASD Study). This processing advantage is accompanied by retention and improvements in key physical properties at low loadings (0.8% wt.).

Nan-O-Sil ASD additive is an ultra high purity, amorphous (no crystallinity), colloidal fumed silica where the particles are discrete and non agglomerated in the form of a bright white powder. Importantly the individual particles are spherical shaped and range in particle size from 0.02 to 0.55 microns (20 to 550 manometers).

Nan-O-Sil ASD improves color dispersion. Blues are bluer. Greens are greener. Nan-O-Sil ASD reduces flow lines and surface defects. Nan-O-Sil ASD is easy to mix with resin pellets in a blender so melt pre-compounding is not required.

Subsequent to this paper/study we have determined that the cycle time reduction provided by Nan-O-sail is a function of nucleation dynamics (see Thermal Kinetics Study)

Major Key Benefits of Nan-O-Sil


  • Nanosil ASD reduces the Injection Molding Cycle time by 30 % to 40 % for most plastics resins like PP, PE, nylons, PBT, PC, LCP, PEEK, and Rigid PVC (read more: PVC Results Summary | Nanosil ASD Study).
  • Nanosil ASD reduces and often eliminates warpage of a molded parts such as rectangular boxes, and other complex geometries.
  • Nanosil ASD Significantly improves the color dispersion and hence it helps to cut down the color concentrate amount resulting in enormous cost savings.
  • Nanosil ASD improves critical part tolerances.
  • Nanosil ASD improves strength properties like tensile strength and toughness of many resins like nylons, PP, PE, and PBT.
  • Nanosil ASD reduces the flow lines and weld lines and improves the overall dimensional stability of the molded parts.
  • It only requires less than 1% (0.8%) of Nanosil ASD (less than three cents of the cost of this additive) to attain all the above benefits.
