The weight-average molar masses of the polymers were
up to 280 kD as measured by GPC. These poly(arylene ether) s exhibited glass transition temperatures up to 361 degrees C in DSC. These polymers showed very high thermal stability up to 558 degrees C for 10% weight loss under synthetic air in TGA. Except 7d-7f, remaining polymers 7a-7c were soluble in a wide range of organic solvents. Transparent thin films of these polymers cast from DCM or NMP exhibited tensile strengths up to 75 MPa and elongation at break up to 41% depending on their exact selleck repeating unit structures. These poly(arylene ether) s showed cut-off wavelength in between 400 and 450 nm except 7d and water absorption were in the range of 0.4 to 0.6%. (C) 2011 Wiley Periodicals, Inc.

“PURPOSE: Selleck Combretastatin A4 To quantify angle changes after phacoemulsification extracapsular cataract extraction using Fourier-domain anterior segment optical coherence tomography (AS-OCT).
SETTING: Department of Ophthalmology, Tri-Service General Hospital, National Defense Medical Center, Taiwan.
DESIGN: Case series.
METHODS:
Fourier-domain AS-OCT examinations were performed in patients between 15 and 91 years of age 1 week before and 1 week after cataract surgery. The angle, angle-opening distance at 500 mu m, and trabecular-iris space area at 500 mu m in the temporal and CH5183284 nasal quadrants were obtained. Patients were then grouped on the basis of age (<60 years or >= 60 years) and the results compared between groups.
RESULTS: Eighty-nine eyes of 80 patients were evaluated. The angle, angle-opening distance at 500 mu m, and trabecular iris space area at 500 pm increased significantly after cataract surgery in the entire study population (P<.001). There were larger postoperative differences in
all 3 parameters in nasal and temporal measurements in patients 60 years or older (all P<.001).
CONCLUSIONS: The angle changed significantly after cataract surgery, particularly in the temporal quadrant and its magnitudes. Postoperative angle changes were larger in older patients, which may be related to the increase in lens volume during the aging process. Fourier-domain AS-OCT can be used as a rapid and safe tool in addition to diagnostic gonioscopy in assessing anterior chamber angles.”
“lpomoea batatas, Agaricus blaze! and Smallanthus sonchifolius are known to favorably influence diabetes mellitus. To clarify their antidiabetic efficacy and hypoglycemic mechanisms, we treated streptozotocin-induced diabetic rats with daily oral feeding of powdered Ipomoea batatas (5 g kg(-1) d(-1)), Agaricus blazei (1 g kg(-1) d(-1)) or Smallanthus sonchifolius (4 g kg(-1) d(-1)) for 2 months.
