Tomas Dvorak, David E Wazer Evaluation of potential proton therapy utilization in a market-based environment CONCLUSIONS: Using existing utilization patterns of highly conformal photon therapy as a proxy, approximately one-third of patients irradiated annually at the authors' institution could be treated with proton therapy, with an incremental cost of 20% across the entire treated patient population. 7/16/2010
Melissa M Murphy, Sing-Chau Ng, Jessica P Simons, Nicholas G Csikesz, Shimul A Shah, Jennifer F Tseng Predictors of major complications after laparoscopic cholecystectomy surgeon, hospital, or patient CONCLUSIONS: Major in-hospital complications after LC are associated with individual patient characteristics rather than surgeon or hospital operative volumes. These results suggest regionalization of general surgical procedures might be unnecessary. Rather, careful patient selection and preoperativ... 7/9/2010
Ruth Schreiber, Marie-Claire Gubler, Olivier Gribouval, Hanna Shalev, Daniel Landau Inherited renal tubular dysgenesis may not be universally fatal Inherited renal tubular dysgenesis (RTD) is caused by mutations in the genes encoding components of the renin-angiotensin cascade: angiotensinogen, renin, angiotensin-converting enzyme (ACE), and angiotensin ΙΙ receptor type 1. It is characterized by oligohydramnios, prematurity, hypotension, hypoca... 7/8/2010

After adjusting for covariates, including age and disease stage, African-American women and Asian women had lower rates of reconstruc... 9/21/2004
Anthony M Stell, Jonathan G Li, Omar A Zeidan, James F Dempsey An extensive log-file analysis of step-and-shoot intensity modulated radiation therapy segment delivery errors We present a study to evaluate the monitor unit (MU), dosimetric, and leaf-motion errors found in the delivery of 91 step-and-shoot IMRT treatment plans performed at three nominal dose rates using a dual modality high energy Linac (Varian 2100 C/D, Varian Medical Systems Inc., Palo Alto, CA) equippe... 7/21/2004
Rafael Manon, Susanta Hui, Prakash Chinnaiyan, John Suh, Eric Chang, Robert Timmerman, See Phan, Rupak Das, Minesh Mehta The impact of mid-treatment MRI on defining boost volumes in the radiation treatment of glioblastoma multiforme Radiation therapy is a central modality in the treatment of glioblastoma multiforme (GBM). Integral to adequate radiation therapy delivery is the appropriate determination of tumor volume and extent at the time treatment is being delivered. As a matter of routine practice, radiation therapy treatmen... 5/27/2004

Akash Nanda, Eleanor B Carson-Walter, Steven Seaman, Thomas D Barber, Jason Stampfl, Sujay Singh, Bert Vogelstein, Kenneth W Kinzler, Brad St Croix TEM8 interacts with the cleaved C5 domain of collagen alpha 3VI Tumor endothelial marker (TEM)8 was uncovered as a gene expressed predominantly in tumor endothelium, and its protein product was recently identified as the receptor for anthrax toxin. Here, we demonstrate that TEM8 protein is preferentially expressed in endothelial cells of neoplastic tissue. We us... 2/12/2004
Hanna Shalev, Igor Romanovsky, Nine V Knoers, Salomon Lupa, Daniel Landau Bladder function impairment in aquaporin-2 defective nephrogenic diabetes insipidus CONCLUSIONS: The severe renal concentrating defect in this type of NDI is associated with the development of hydroureteronephrosis followed by bladder enlargement and dysfunction. Careful follow-up is needed in order to assure that no bladder outlet obstruction and/or renal insufficiency develop. 2/10/2004
Akash Nanda, Brad St Croix Tumor endothelial markers new targets for cancer therapy PURPOSE OF REVIEW: Targeting the endothelial cells that line tumor infiltrating blood vessels is a new anticancer strategy that has gained widespread support from biologists and clinicians. Here we highlight different approaches currently being used to target tumor endothelium and discuss new avenue... 12/20/2003
Peter B Johansen, Yael Segev, Daniel Landau, Moshe Phillip, Allan Flyvbjerg Growth hormone GH hypersecretion and GH receptor resistance in streptozotocin diabetic mice in response to a GH secretagogue The growth hormone (GH) and insulin-like growth factor I (IGF-I) axis were studied in streptozotocin (STZ) diabetic and nondiabetic female mice following intravenous (IV) injection of the GH secretagogue (GHS) ipamorelin or saline. On day 14, blood samples were obtained before and 10 minutes after t... 11/25/2003
Fred J P Feuillet, Diane E J E Robinson, Steven D Bull An E-selective synthesis of trisubstituted E-alpha,beta-unsaturated acid derivatives Potassium alkoxides of N-acyloxazolidin-2-one derived syn-aldolates undergo a novel tandem intramolecular cyclisation elimination reaction to afford trisubstituted (E)-alpha,beta-unsaturated amides in high d.e., which may be converted into their corresponding acids or oxazolines in good yield. 9/19/2003

The genes mutated in NPHP1 and NPHP4 have been identified, and a gene locus associated with infantile nephronophthisis (NPHP2) was mapped. The kidney phenotype of NPHP2 combines clinica... 7/23/2003
Luis J Herrera, Hiran C Fernando, Yaron Perry, William E Gooding, Percival O Buenaventura, Neil A Christie, James D Luketich Radiofrequency ablation of pulmonary malignant tumors in nonsurgical candidates CONCLUSION: This pilot study demonstrates the feasibility of radiofrequency ablation for small peripheral lung tumors. Larger tumors responded poorly. Additional trials are needed to determine safety and efficacy. 4/17/2003
Gal Finer, Hanna Shalev, Ohad S Birk, Dalia Galron, Nikola Jeck, Levana Sinai-Treiman, Daniel Landau Transient neonatal hyperkalemia in the antenatal ROMK defective Bartter syndrome CONCLUSIONS: Early postnatal hyperkalemia, sometimes severe, may complicate antenatal BS associated with ROMK mutations. Its association with hyponatremia and hyperreninemic hyperaldosteronism may erroneously suggest the diagnosis of pseudohypoaldosteronism type 1. The expression of ROMK in both the... 3/18/2003
Daniel Landau, Eytan Israel, Inessa Rivkis, Leonid Kachko, Bieke F Schrijvers, Allan Flyvbjerg, Moshe Phillip, Yael Segev The effect of growth hormone on the development of diabetic kidney disease in rats CONCLUSIONS: GH-treated diabetic rats had less hyperfiltration and more albuminuria, concomitant with more glomerular matrix deposition, when compared with regular diabetic animals. This was associated with a significant increase in renal IGFBP-1, and dissociated from IGF-I changes. Thus, in this mo... 3/15/2003

John L Francis, George J Palmer, Rebecca Moroose, Alane Drexler Comparison of bovine and porcine heparin in heparin antibody formation after cardiac surgery CONCLUSIONS: This study confirms the high frequency of heparin-PF4 antibodies after coronary artery bypass grafting and demonstrates a significantly higher incidence after bovine heparin. However, because some patients may seroconvert after discharge, our study may underestimate the true incidence. 1/23/2003

Most AQP2 missense mutants in recessive NDI are retained in the en... 8/23/2002
William R Tyor, Nicholas Avgeropoulos, George Ohlandt, Edward L Hogan Treatment of spinal cord impact injury in the rat with transforming growth factor-beta To investigate the contribution of cytokines, proinflammatory TNF-alpha and inhibitory TGF-beta, to spinal cord injury (SCI) in a rat model, two studies were performed using adult Sprague-Dawley rats which were injured at T9/T10. In the first study, rats were sacrificed at 1, 6, 24, 96 and 168 h aft... 7/20/2002

L J Herrera, H Lugo-Vicente Primary embryonal rhabdomyosarcoma of the breast in an adolescent female a case report Rhabdomyosarcoma is the most common soft tissue sarcoma in children. Primary breast location has been reported rarely in the literature. Most rhabdomyosarcomas encountered in the breast more commonly are metastatic disease from some primary foci in another part of the body. This report addresses the... 11/5/1998
