Objective: To assess and compare the effects of low-intensity pulsed ultrasound stimulation (LIPUS) and low-level laser therapy (LLLT) on the bone mineral density (BMD) of bone formed through distraction osteogenesis (DO) using dual energy x-ray absorptiometry (DEXA). Background data: LIPUS and LLLT are noninvasive supporting treatment concepts used for wound healing. LIPUS has been used to accelerate bone healing through the therapeutic effect arising from piezoelectric and angiogenetic effects on cell membranes. LLLT known as "photobiomodulation'' is used in the treatment of soft and hard tissue injuries. Methods: The study was conducted with 15 New Zealand rabbits randomly divided into three groups of 5 according to treatment, as follows: Group A: DO was performed with no further treatment; Group B: DO was performed followed by 30mW/cm(2) LIPUS at 1 Mhz for 20 min/day during the distraction period; Group C: DO was performed followed by 25mW/cm(2) LLLT at 650 nm for 10 min/day during the distraction period. DEXA was used to examine the treated areas prior to surgery and at 30 and 60 days postoperatively. Results: In the control group, the mean BMD values at both 30 and 60 days postoperatively were below the baseline level, whereas they were above at the same time intervals in the LIPUS group. In the LLLT group, the mean BMD value at 30 days postoperatively was below the baseline level, whereas it was above the baseline level at 60 days postoperatively. Conclusions: LIPUS and LLLT applied during the distraction period accelerated the DO treatment.

The molecular investigation of the effects of simvastatin, a cholesterol reducing drug, on different rat skeletal muscle tissues
Şimşek Özek, Nihal; Severcan, Feride; Department of Biology (2007)
In the present study Fourier Transform Infrared (FTIR) and Attenuated Total Reflectance FTIR (ATR-FTIR) Spectroscopy were used to examine the effects of simvastatin on structure, composition and function of macromolecules of three different rat skeletal muscles EDL (Extensor Digitorium Longus), DIA (Diaphragm) and SOL (Soleus) containing different amount of slow and fast twitch fibers, at molecular level. Simvastatin, a lipophilic statin, is widely used in the treatment of hypercholesterolemia and cardiovas...
The Effect of Labeled/Unlabeled Prior Information for Masseter Segmentation
Tabar, Yousef Rezaei; Ulusoy, İlkay (Hindawi Limited, 2013-01-01)
Several segmentation methods are implemented and applied to segment the facial masseter tissue from magnetic resonance images. The common idea for all methods is to take advantage of prior information from different MR images belonging to different individuals in segmentation of a test MR image. Standard atlas-based segmentation methods and probabilistic segmentation methods based on Markov random field use labeled prior information. In this study, a new approach is also proposed where unlabeled prior infor...
The effect of diabetes on rat skeletal muscle tissues at molecular level
Bozkurt, Özlem; Severcan, Feride; Department of Biology (2006)
In the present study Fourier Transform Infrared Spectroscopy was used to examine the effects of streptozotocin-induced diabetes mellitus on the structural components of slow- and fast-twitch rat skeletal muscles, at molecular level. Diabetes mellitus is a chronic disorder of carbohydrate, fat and protein metabolism, which is characterized by hyperglycemia caused by a defective or deficient insulin secretory response. The effect of diabetes is seen on a variety of tissues leading to important secondary compl...
