Dopamine b-monooxygenase (DBM), a cuproenzyme, converts dopamine to norepinephrine in selected cells. Studies were conducted in albino rats to resolve the known paradox of DBM after copper deficiency in which metabolite analyses of tissues suggest lower activity, whereas direct assay of homogenates suggests enhanced activity. After 4 wk of postweanling copper deficiency, male Holtzman rats exhi...

We introduce the multi-prediction deep Boltzmann machine (MP-DBM). The MPDBM can be seen as a single probabilistic model trained to maximize a variational approximation to the generalized pseudolikelihood, or as a family of recurrent nets that share parameters and approximately solve different inference problems. Prior methods of training DBMs either do not perform well on classification tasks ...

A coplanar millimeter wave doubler MMIC covering the entire G-band was developed. Based on a 50 nm metamorphic HEMT technology, the circuit demonstrates an output power of more than –12 dBm between 150and 220 GHz for an input power of 0 dBm. By increasing the input power to 12 dBm an output power exceeding 0 dBm was obtained in the frequency range between 180and 220 GHz. Good fundamental reject...

INTRODUCTION: Iliac crest autograft is considered the gold standard graft material despite limitations in the quantity available and potential complications associated with harvesting procedure. These disadvantages have motivated clinicians and investigators to seek alternative graft materials to extend, enhance and/or substitute for autograft. Examples of such alternatives include: allografts,...

Increasing DBM Reliability using Distribution Independent Tests and Information Fusion Techniques Vidya Rajagopalan In deformation based morphometry (DBM) group-wise differences in brain structure are measured using deformable registration and some form of statistical test. However, it is known that DBM results are sensitive to both the registration method and statistical test used. Given the l...

This study was designed to investigate the optimal combination of known osteogenic biomaterials with shape conforming struts to achieve calvarial vault reconstruction, using a canine model. Eighteen adolescent beagles were divided equally into 6 groups. A critical-size defect of 6 x 2 cm traversed the sagittal suture. The biomaterials used for calvarial reconstruction were demineralized perfora...

OBJECTIVE To compare the fusion rate of a hydroxyapatite demineralized bone matrix (DBM) with post-laminectomy acquired autograft in lumbar interbody fusion surgery and to evaluate the correlation between fusion rate and clinical outcome. METHODS From January 2013 to April 2014, 98 patients underwent lumbar interbody fusion surgery with hydroxyapatite DBM (HA-DBM group) in our institute. Of t...
