Department of Microbiology and Immunology Faculty Papers

The Tight Skin mouse is a genetically induced animal model of tissue fibrosis caused by a large in-frame mutation in the gene encoding fibrillin-1 (Fbn-1). We examined the influence of gender on the collagen content of tissues in C57BL/6J wild type (+/+) and mutant Tight Skin (Tsk/+) mice employing hydroxyproline assays. Tissue sections were stained with Masson's trichrome to identify collagen in situ. Adult Tsk/+ mice skin contains ~15% more collagen, on average, than skin from +/+ mice of the same gender. The heart of Tsk/+ males had significantly more collagen than that of +/+ males. No significant gender differences …

Unplanned Readmission After Total Joint Arthroplasty: Rates, Reasons, And Risk Factors., Benjamin Zmistowski, Camilo Restrepo, Jordan Hess, Darius Adibi, Soltan Cangoz, Javad Parvizi

Rothman Institute Papers

BACKGROUND: There has been a major and alarming increase in readmission rates following total joint arthroplasty. With proposed changes in reimbursement policy, increased rates of unplanned readmission following arthroplasty will penalize providers. In particular, it has been proposed that specific complications-so-called "zero-tolerance" complications-are unacceptable and that their treatment will not qualify for reimbursement. The purpose of this study was to identify the incidence, causes, and risk factors for readmission following total joint arthroplasty.

METHODS: An institutional arthroplasty database was utilized to identify those patients undergoing total knee or hip arthroplasty from January 2004 through December 2008. A total of 10,633 …

Combination Of Necroptosis And Apoptosis Inhibition Enhances Cardioprotection Against Myocardial Ischemia-Reperfusion Injury., Shizuka Koshinuma, Masami Miyamae, Kazuhiro Kaneda, Junichiro Kotani, Vincent M. Figueredo

Division of Cardiology Faculty Papers

PURPOSE: Necroptosis has been proposed as a mode of cell death that is a caspase-independent programmed necrosis. We investigated whether necroptosis is involved in myocardial ischemia-reperfusion injury in isolated guinea pig hearts and, if so, whether simultaneous inhibition of necroptosis and apoptosis confers enhanced cardioprotection.

METHODS: Isolated perfused guinea pig hearts were subjected to 30 min ischemia and 4 h reperfusion (control = CTL, n = 8). Necrostatin-1 (necroptosis inhibitor, 10 μM), Z-VAD (apoptosis inhibitor, 0.1 μM) and both inhibitors were administered starting 5 min before ischemia and during the initial 30 min of reperfusion (Nec, Z-VAD, Nec + Z-VAD; …

Fn14•Trail Effectively Inhibits Hepatocellular Carcinoma Growth., Alexandra Aronin, Shira Amsili, Tatyana B Prigozhina, Kobi Tzdaka, Jacob Rachmilewitz, Noam Shani, Mark L Tykocinski, Michal Dranitzki Elhalel

Department of Medical Genetics Faculty Papers

BACKGROUND: New strategies for the treatment of hepatocellular carcinoma (HCC) are needed, given that currently available chemotherapeutics are inefficient. Since tumor growth reflects the net balance between pro-proliferative and death signaling, agents shifting the equilibrium toward the latter are of considerable interest. The TWEAK:Fn14 signaling axis promotes tumor cell proliferation and tumor angiogenesis, while TRAIL:TRAIL-receptor (TRAIL-R) interactions selectively induce apoptosis in malignant cells. Fn14•TRAIL, a fusion protein bridging these two pathways, has the potential to inhibit tumor growth, by interfering with TWEAK:Fn14 signaling, while at the same time enforcing TRAIL:TRAIL-R-mediated apoptosis. Consequently, Fn14•TRAIL's capacity to inhibit HCC growth was tested. …

Snapin, Positive Regulator Of Stimulation- Induced Ca(2+) Release Through Ryr, Is Necessary For Hiv-1 Replication In T Cells., Shigemi M Kinoshita, Amane Kogure, Shizuka Taguchi, Garry P Nolan

Department of Microbiology and Immunology Faculty Papers

To identify critical host factors necessary for human immunodeficiency virus 1 (HIV-1) replication, large libraries of short-peptide-aptamers were expressed retrovirally. The target of one inhibitor peptide, Pep80, identified in this screen was determined to be Snapin, a protein associated with the soluble N-ethyl maleimide sensitive factor adaptor protein receptor (SNARE) complex that is critical for calcium-dependent exocytosis during neurotransmission. Pep80 inhibited Ca(2+) release from intracellular stores and blocked downstream signaling by direct interruption of the association between Snapin and an intracellular calcium release channel, the ryanodine receptor (RyR). NFAT signaling was preferentially abolished by Pep80. Expression of Snapin overcame Pep80-mediated …

Igf-Ir Promotes Prostate Cancer Growth By Stabilizing Α5Β1 Integrin Protein Levels., Aejaz Sayeed, Carmine Fedele, Marco Trerotola, Kirat K Ganguly, Lucia R Languino

Department of Cancer Biology Faculty Papers

Dynamic crosstalk between growth factor receptors, cell adhesion molecules and extracellular matrix is essential for cancer cell migration and invasion. Integrins are transmembrane receptors that bind extracellular matrix proteins and enable cell adhesion and cytoskeletal organization. They also mediate signal transduction to regulate cell proliferation and survival. The type 1 insulin-like growth factor receptor (IGF-IR) mediates tumor cell growth, adhesion and inhibition of apoptosis in several types of cancer. We have previously demonstrated that β1 integrins regulate anchorage-independent growth of prostate cancer (PrCa) cells by regulating IGF-IR expression and androgen receptor-mediated transcriptional functions. Furthermore, we have recently reported that IGF-IR …

Meditation: Should A Cardiologist Care?, Stephen Olex, Andrew B. Newberg, Md, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

Meditation refers to a family of practices that may share many similarities, but can have differences in underlying methods and goals. Religious and spiritual associations are common but are not requisite for meditation practice and it should be recognized that the basis of many if not all practices is the training of the brain and body, a process that appears to have profound effects on both structure and function. In recent decades there has been interest regarding the effects of these ancient practices on the cardiovascular system, as meditation has intuitive appeal for benefit in this area. Though there is …

Analyzing The Health Care Cost Curve: A Case Study., Robert D. Lieberthal

College of Population Health Faculty Papers

This case study uses data from a self-insured employer plan to perform an analysis into the properties of the health care cost curve. The analysis shows that one statistical property of the health care cost curve is that costs rise continuously, not on an annual or monthly basis. Graphical analysis indicates that managed care techniques used to restrain costs can also smooth utilization, producing the continuously growing cost curve observed. The analysis further illustrates that there is no one "cost curve"-analysis must be segmented by population. Finally, the power of predictive models to fit the cost curve varies by population. …

Common Peroneal Nerve Palsy Following Total Knee Arthroplasty: Prognostic Factors And Course Of Recovery., Jai Hyung Park, Md, Camilo Restrepo, Md, Robert Norton, Md, Steven Mandel, Md, Peter F. Sharkey, Md, Javad Parvizi, Md

Department of Orthopaedic Surgery Faculty Papers

Common peroneal nerve palsy (CPNP) is a serious complication following total knee arthroplasty (TKA). There is little information regarding the clinical course and prognostic factors for recovery. Between January 2000 and December 2008, 44 patients (0.53%) developed CPNP following TKA and were matched to 100 control patients based on year of surgery, type of surgery and surgeon. Regression analysis was performed to identify prognostic factors for recovery. A significant difference was seen in CPNP patients who were on average younger (62.1 years) and had higher BMI (34.5 kg/m(2)) than those who did not have nerve palsy (67.5 years and 31.8 …

Thioredoxin Reductase Was Nitrated In The Aging Heart After Myocardial Ischemia/Reperfusion., Ke Wang, Jie Zhang, Xiaoliang Wang, Xin Liu, Lin Zuo, Kehua Bai, Jianyu Shang, Lu Ma, Teng Liu, Li Wang, Wen Wang, Xin-Liang Ma, Huirong Liu

Department of Emergency Medicine Faculty Papers

The age-related loss of anti-oxidant defense reduces recovery from myocardial ischemia/reperfusion injury (MI/R) in aged people. Our previous data showed that inactivation of thioredoxin (Trx) was involved in enhanced aging MI/R injury. Thioredoxin reductase (TrxR), the enzyme known to regulate Trx, is less efficient with age. The aim of the current study was to determine why TrxR activity was reduced and whether reduced TrxR activity contributed to enhanced aging MI/R injury. Both Trx and TrxR activity were decreased in the aging heart, and this difference was further amplified after MI/R. However, MI/R injury did not change TrxR expression between young …
