“Objective. This study investigated the

effect of locally immobilized bisphosphonates and systemic estrogen replacement therapy on fixation of hydroxyapatite-coated screws in ovariectomized rats.

Study design. Twelve weeks after being ovariectomized, each of the 20 rats received 2 hydroxyapatite-coated screws in the proximal see more tibia, with or without immobilized bisphosphonates. Half of the animals also received subcutaneous injections of 17 beta-estradiol. Thus, there were 4 groups: control, estrogen, bisphosphonates, and estrogen plus bisphosphonates. Tibiae with screws were measured by microscopic computerized tomography and push-out test 12 weeks after implantation.

Results. Combined treatment had the strongest effects, with the bone volume ratio around screws and the percentage of osteointegration significantly increased by 2.3-fold and 1.9-fold and the push-out force by 3.3-fold compared with untreated control samples. Monotherapy also enhanced the fixation of screws, although less.

Conclusions. Systemic estrogen replacement therapy and locally immobilized bisphosphonates

had additive effects on fixation of hydroxyapatite-coated screws in ovariectomized rats. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010; 109: 700-705)”
“The authors characterize AlInN/GaN structures on AlN templates for high-performance ultraviolet photodiodes. selleck screening library AlInN/GaN structures were grown with various growth parameters by metal organic chemical vapor deposition. In the case of nearly lattice-matched to GaN underlying layers, AlInN/GaN structures are found to have smooth interface. AlInN layers grown at the low pressure are confirmed to have high crystal quality from x-ray diffraction measurements and good surface morphology

from atomic force microscope images. The noble AlInN-based photodiodes were fabricated. Their performances show the leakage current of 48 nA at a reverse voltage of 5 V and the cutoff wavelength around 260 nm. A cutoff-wavelength responsivity of 21.84 mA/W is obtained, corresponding to quantum efficiency of 10.6%. It may be possible to realize high-performance ultraviolet photodiodes by further optimizing AlInN/GaN structures. GDC 0032 chemical structure c 2011 American Institute of Physics.

“The goal of this study is to determine the feasibility of intravenous gemcitabine and an intraperitoneal platinum agent in the treatment of patients with ovarian cancer. We performed a retrospective chart review of patients with primary, persistent or recurrent ovarian cancer, who received intravenous gemcitabine and an intraperitoneal platinum agent. Patients received gemcitabine (750 mg/m(2)) intravenous on days 1 and 8 and cisplatin (100 or 60 mg/m(2)) intraperitoneal on day 1 every 21 – 28 days.
