Bone marrow cell homing to sites of acute tibial fracture: ⁸⁹Zr-oxine cell labeling with positron emission tomographic imaging in a mouse model

Kingsley O. Asiedu, Munira Ferdousi, Phuongnga T. Ton, Stephen S. Adler, more

EJNMMI Research > 2018 > 8 > 1 > 1-11

Background Bone fracture healing is dependent upon the rapid migration and engraftment of bone marrow (BM) progenitor and stem cells to the site of injury. Stromal cell-derived factor-1 plays a crucial role in recruiting BM cells expressing its receptor CXCR4. Recently, a CXCR4 antagonist, plerixafor, has been used to mobilize BM cells into the blood in efforts to enhance cell migration to sites of...

Tadanobu Nagaya, Shuhei Okuyama, Fusa Ogata, Yasuhiro Maruoka, more

Gastric Cancer > 2019 > 22 > 3 > 463-472

Background Peritoneal dissemination (PD) of abdominal malignancies is a common form of metastasis and its presence signals a poor prognosis. New treatment is required for patients with PD. Near infrared photoimmunotherapy (NIR-PIT) is a highly selective tumor treatment that employs an antibody–photo-absorber conjugate (APC). In this study, we investigate in vitro and in vivo efficacy of trastuzumab...

Falguni Basuli, Xiang Zhang, Mark R. Williams, Jurgen Seidel, more

Nuclear Medicine and Biology > 2018 > 62-63 > C > 63-70

Equilibrium single-photon radionuclide imaging methods for assessing cardiac function and the integrity of the vascular system have long been in use for both clinical and research purposes. However, positron-emitting blood pool agents that could provide PET equivalents to these (and other) clinical procedures have not yet been adopted despite technical imaging advantages offered by PET. Our goal was...

Follow-up of negative MRI-targeted prostate biopsies: when are we missing cancer?

Samuel A. Gold, Graham R. Hale, Jonathan B. Bloom, Clayton P. Smith, more

World Journal of Urology > 2019 > 37 > 2 > 235-241

Introduction Multiparametric magnetic resonance imaging (mpMRI) has improved clinicians’ ability to detect clinically significant prostate cancer (csPCa). Combining or fusing these images with the real-time imaging of transrectal ultrasound (TRUS) allows urologists to better sample lesions with a targeted biopsy (Tbx) leading to the detection of greater rates of csPCa and decreased rates of low-risk...
