Stanford University, Palo Alto, CA, USA The integration of PET’s ability to visualize and quantify molecular signatures and MRI’s excellent anatomical information shows great promise to be a powerful tool for disease characterization. However, the high cost of simultaneous PET/MRI has limited its availability. To address this problem, we have developed an RF-penetrable PET insert that can be pl...

in this work, ternary polymer blends based on polypropylene (pp)/ polyethylene terephthalate (pet) /poly(styrene-b (ethylene-co-butylene)-b-styrene) (sebs) triblock copolymer and a reactive maleic anhydride grafted sebs (sebs-g-mah) at various compositions were prepared by co-rotating twin screw extruder. the effects of pet, sebs and sebs-g-mah compatibilizer on morphology of the blends were ex...

Modern technology has changed people's lifestyles, including how to raise pets. Pet is an animal kept at home or in a cage and exclusively cared for by its owner. Recently, more people owning This had led questions related the hygiene health of An unkempt pet can cause problems owner, so numerous stores have emerged help owners provide their animals with care they require. However, many shops s...

Translational and Molecular Imaging Institute, Icahn School of Medicine at Mount Sinai, NY, NY, USA Current MR/PET systems employ segmentation of MR images and subsequent assignment of empirical attenuation map values for quantitative PET reconstruction. In this current study we examine the quantitative differences between our carotid artery imaging protocol on both a PET/CT and an MR/PET scann...

A patient with a history of adenoid cystic carcinoma of the nasal cavity presented himself with bone pain and an elevated PSA level. On suspicion of metastatic prostate cancer a 68Ga-PSMA PET-CT was performed. The PET-CT showed numerous lung and non-sclerotic bone metastasis. Biopsy of a bone metastasis was performed and pathology showed adenoid cystic carcinoma instead of prostate cancer. Immu...

PURPOSE Helicobacter pylori is a widely distributed gram-negative bacterium that infects the human stomach and duodenum. HpaA is a H. pylori-specific lipoprotein that has been shown to be an effective protective antigen against H. pylori infection. HpaA of H. pylori as a vaccine antigen is fully competent for stimulation of immune responses. The aim of this project is cloning, expression, and p...

Coordinated serotonin (5-HT) synthesis and reuptake depends on coexpression of Tph2, Aadc (Ddc), and Sert (Slc6a4) in brain 5-HT neurons. However, other gene products play critical roles in brain 5-HT synthesis and transport. For example, 5-HT synthesis depends on coexpression of genes encoding the enzymatic machinery necessary for the production and regeneration of tetrahydrobiopterin (BH4). I...

due to the widespread applications of xylitol dehydrogenase, an enzyme used for the production of xylitol, the present study was designed for the cloning of xylitol dehydrogenase gene from glcunobacter oxydans dsm 2003. after extraction of genomic dna from this bacterium, xylitol dehydrogenase gene was replicated using polymerase chain reaction (pcr). the amplified product was entered into ptz5...

Institute of Medical Physics, Department of Engineering Physics, Tsinghua University, Beijing, China This work is to replace PET ring in human brain PET/MR system with a dedicated wearable PET insert, aimed at improving both patient feasibility and system performance for brain imaging. The designed PET/MR system includes two parts: the inside parts, including a radio frequency (RF) coil and PET...
