Sixty-Four-Slice Multidetector Computed Tomography: The Future Of Ed Cardiac Care, Alexander T. Limkakeng, Ethan Halpern, Kevin M. Takakuwa

Department of Radiology Faculty Papers

Multidetector computed tomography (MDCT) imaging, a technological advance over traditional CT, is a promising possible alternative to cardiac catheterization for evaluating patients with chest pain in the emergency department (ED). In comparison with traditional CT, MDCT offers increased spatial and temporal resolution that allows reliable visualization of the coronary arteries. In addition, a "triple scan," which includes evaluation for pulmonary embolism and thoracic aortic dissection, can be incorporated into a single study. This test will enable emergency physicians to rapidly evaluate patients for life-threatening illnesses and may allow safer and earlier discharges of many patients with chest pain in comparison …

A Phase Ii Study Of Acute Toxicity For Celebrex(Tm) (Celecoxib) And Chemoradiation In Patients With Locally Advanced Cervical Cancer: Primary Endpoint Analysis Of Rtog 0128, David K. Gaffney, Kathryn Winter, Adam P. Dicker, Brigitte Miller, Patricia J. Eifel, Janice Ryu, Vilija Avizonis, Mitch Fromm, Kathryn Greven

Department of Radiation Oncology Faculty Papers

Purpose: To determine treatment-related acute toxicity rates in patients with locally advanced cervical cancer treated by oral celecoxib, i.v. cisplatin and 5-FU, and concurrent pelvic radiation therapy.

Methods and Materials: Eligible patients on this RTOG Phase I-II study for advanced cervix cancer included FIGO Stage IIB-IVA or patients with FIGO Stage IB through IIA with biopsy proven pelvic node metastases ortumor size >5 cm. Patients were treated with pelvic radiotherapy and brachytherapy. Celecoxib was prescribed at 400 mg twice daily beginning on day 1 for 1 year. Cisplatin (75 mg/m2) and 5-FU (1g/m2 for 4 days) were administered every 3 …

The Effect Of Hus1 On Ionizing Radiation Sensitivity Is Associated With Homologous Recombination Repair But Is Independent Of Non-Homologous End-Joining, Robert S. Weiss, Xiang Wang, Baocheng Hu, Ya Wang

Department of Radiation Oncology Faculty Papers

Mammalian Hus1 plays an important role in maintaining genomic integrity. Cells lacking mouse Hus1 are hypersensitive to DNA damage inducers including UV and camptothecin (CPT). By using clonogenic assay, we show here that Hus1 deficient mouse cells are hypersensitive to ionizing radiation (IR) compared with their Hus1-positive counterparts. However, these cells show similar induction levels and similar rejoining rates of DNA double strand breaks (DSBs) following IR, indicating that the effect of Hus1 on cell radiosensitivity is independent of non-homologous end-joining (NHEJ). By combining an I-SceI-induced-DNA DSBs system and a siRNA approach, we also show that knocking down Hus1 decreases …
