Cannabinoid Receptor Interacting Protein Suppresses Agonist-Driven Cb1 Receptor Internalization And Regulates Receptor Replenishment In An Agonist-Biased Manner, Lawrence C. Blumes, Sandra Leone-Kabler, Deborah J. Luessen, Glenn S. Marrs, Erica Lyons, Caroline E. Bass, Rong Chen, Dana E. Selley, Allyn C. Howlett

Neurology Publications

Cannabinoid receptor interacting protein 1a (CRIP1a) is a CB1 receptor (CB1R) distal C-terminus-associated protein that modulates CB1R signaling via G proteins, and CB1R down-regulation but not desensitization (Blume et al. [2015] Cell Signal., 27, 716-726; Smith et al. [2015] Mol. Pharmacol., 87, 747-765). In this study, we determined the involvement of CRIP1a in CB1R plasma membrane trafficking. To follow the effects of agonists and antagonists on cell surface CB(1)Rs, we utilized the genetically homogeneous cloned neuronal cell line N18TG2, which endogenously expresses both CB1R and CRIP1a, and exhibits a well-characterized endocannabinoid signaling system. We developed stable CRIP1a-over-expressing and CRIP1a-siRNA-silenced knockdown …

Projecting Productivity Losses For Cancer-Related Mortality 2011 – 2030, Alison Pearce, Cathy Bradley, Paul Hanly, Ciaran O’Neill, Audrey Alforque Thomas, Michal Molcho, Linda Sharp

Background

When individuals stop working due to cancer this represents a loss to society – the loss of productivity. The aim of this analysis was to estimate productivity losses associated with premature mortality from all adult cancers and from the 20 highest mortality adult cancers in Ireland in 2011, and project these losses until 2030.

Methods

An incidence-based method was used to estimate the cost of cancer deaths between 2011 and 2030 using the Human Capital Approach. National data were used for cancer, population and economic inputs. Both paid work and unpaid household activities were included. Sensitivity analyses estimated the …

Sirt1 Expression Is Associated With Cd31 Expression In Blood Cells From Patients With Chronic Obstructive Pulmonary Disease, Ryo Kato, Shiro Mizuno, Maiko Kadowaki, Kohei Shiozaki, Masaya Akai, Ken Nakagawa, Taku Oikawa, Masaharu Iguchi, Kazuhiro Osanai, Takeshi Ishizaki, Norbert F. Voelkel, Hirohisa Toga

Emergency Medicine Publications

Background: Cigarette smoke induced oxidative stress has been shown to reduce silent information regulator 1 (Sirt1) levels in lung tissue from smokers and patients with COPD patients. Sirt1 is known to inhibit endothelial senescence and may play a protective role in vascular cells. Endothelial progenitor cells (EPCs) are mobilized into circulation under various pathophysiological conditions, and are thought to play an important role in tissue repair in chronic obstructive lung disease (COPD). Therefore, Sirt1 and EPC-associated mRNAs were measured in blood samples from patients with COPD and from cultured CD34+ progenitor cells to examine whether these genes are associated with …

The Lived Experience Of Bipolar Disorder: A Systematic Review And Meta-Synthesis, Joseph Walsh, Jacqueline Corcoran, Paula Crooks, Nathan Cooke, Cory Cummings

Social Work Publications

The purpose of this meta-synthesis was to review the available qualitative research on the lived experience of persons with bipolar disorder in order to find common themes that may enhance practitioner understanding. In this meta-synthesis, limited to studies conducted in the United States, 12 studies involving 234 participants met the authors’ inclusion criteria, and the following four major crosscutting themes, with subthemes, were identified: the process of acceptance of the diagnosis; its negative impact on relationships; internal coping strategies; and reliance on social support. Implications of these findings for direct practice are explored.

What Are The Needs Of Older Adults?, Edward F. Ansello

Director's Editorials from Age in Action

Mobility, social connections, health declines, lifelong learning, safety, caretakers or caregivers speak to interdependence or assisted autonomy, rather than to independence. Realizing the best of ourselves means that we are engaged or interdependent with others.

Animal Cruelty And Elder Abuse, Edward F. Ansello

Director's Editorials from Age in Action

Continuing and expanding the American Psychological Association's guidance that those in counseling roles be alert to and ask questions about care of animals could provide some early warnings, perhaps in time to avoid harm to both animals and people. Encouraging our children to interact with kindness towards animals can’t help but pay dividends over the life course. We need to pay attention to the link of indifference or neglect of pets leading to the same with humans, with those in later life.

Director's Editorials from Age in Action

If aging in place is the goal, simple targeted improvements to one’s home and ability to function in it may be central.

Neighborhood Walkability And Health, Edward F. Ansello

Director's Editorials from Age in Action

The apparent benefit of neighborhood walkability suggests that it may be an important health-related consideration in the lives of everyday people. Most of the elements in the walkability index reflect components in the environment, so these may be relevant across the continuum of impairments, meaning that walkable neighborhoods themselves may have positive impact on the daily lives of people with physical or intellectual disabilities.

Microstructured Thin Film Nitinol For A Neurovascular Flow-Diverter, Yanfei Chen, Connor Howe, Yongkuk Lee, Seongsik Cheon, Woon-Hong Yeo, Youngjae Chun

Mechanical and Nuclear Engineering Publications

A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, ‘flow-diverter’, can divert blood flow away from the aneurysm sac. People found that a flow-diverter based on thin film nitinol (TFN), works very effectively, however there are no studies proving the mechanical safety in irregular, curved blood vessels. Here, we study the mechanical behaviors and structural safety of a novel microstructured TFN membrane through the computational and experimental studies, which establish the fundamental aspects of stretching and bending mechanics …

Minimizing Loss Of Balance And Falls With Personal Walkers, Michael Berger, Galen Kellner, David Le, Anthony Renninger

Capstone Design Expo Posters

Falls within the Older Adult community lead to roughly 734,000 hospital admissions annually with 87% attributed to walker use. In order to reduce the amount of falls due to walker use our objective was to create a system that detects an increased likelihood of a fall occurring, notifies the user of improper positioning, and can intervene by application of an automatic braking system to stabilize the walker; effectively training the user to have a more proper walking form and posture reducing the risk of a fall. In order to accomplish this goal, final deliverables included a working prototype and validation …

MD Student Summer Research Fellowship Program Posters

• Triplatin and Triplatin NC suppressed cell growth of both Breast Cancer and Pancreatic Cancer in a dose dependent manner in vitro.

• Both Triplatin and TriplatinNC demonstrated growth suppression of the primary breast tumor. A single animal (in the TriplatinNCgroup) was sacrificed due to weight loss.

• In the advanced ex vivo lung metastasis model our most striking results were observed, where the agents nearly prohibited lung metastasis from occurring.

• In the pancreatic cancer peritoneal carcinomatosis model, Triplatin reduced total tumor burden. Mouse survival was significantlyenhanced by the Triplatin treatment group and no mouse developed weight loss more …

Retrospective Review Of Intra-Articular Hip Steroid Injections And Their Association With Rapidly-Progressive Osteoarthritis, Christopher Bednarz, Robert O'Connell Md, Gregory Golladay Md, William Jiranek Md

MD Student Summer Research Fellowship Program Posters

Based on strict inclusion criteria, 109 patients were eligible for analysis in this study. Of these patients, 23 developed RPOA—representing an incidence of 21%.

The characteristics of patients who went on to develop RPOA in this study were: worse initial Kellgren-Lawrence grade and older age.

Future studies of larger sample size that also include outcomes of patients who did not receive intra-articular injections will be needed to establish a causal relationship between these injections and RPOA.

Sestrin2 Is Induced By Glucose Starvation Via The Unfolded Protein Response And Protects Cells From Non-Canonical Necroptotic Cell Death, Boxiao Ding, Anita Parmigiani, Ajit S. Divakaruni, Kellie Archer, Anne N. Murphy, Andrei V. Budanov

Human and Molecular Genetics Publications

Sestrin2 is a member of a family of stress responsive proteins, which controls cell viability via antioxidant activity and regulation of the mammalian target of rapamycin protein kinase (mTOR). Sestrin2 is induced by different stress insults, which diminish ATP production and induce energetic stress in the cells. Glucose is a critical substrate for ATP production utilized via glycolysis and mitochondrial respiration as well as for glycosylation of newly synthesized proteins in the endoplasmic reticulum (ER) and Golgi. Thus, glucose starvation causes both energy deficiency and activation of ER stress followed by the unfolding protein response (UPR). Here, we show that …

Rnaseq Analyses Identify Tumor Necrosis Factor-Mediated Inflammation As A Major Abnormality In Als Spinal Cord, David G. Brohawn, Laura C. O'Brien, James P. Bennett

Human and Molecular Genetics Publications

ALS is a rapidly progressive, devastating neurodegenerative illness of adults that produces disabling weakness and spasticity arising from death of lower and upper motor neurons. No meaningful therapies exist to slow ALS progression, and molecular insights into pathogenesis and progression are sorely needed. In that context, we used high-depth, next generation RNA sequencing (RNAseq, Illumina) to define gene network abnormalities in RNA samples depleted of rRNA and isolated from cervical spinal cord sections of 7 ALS and 8 CTL samples. We aligned >50 million 2X150 bp paired-end sequences/sample to the hg19 human genome and applied three different algorithms (Cuffdiff2 …

Krüppel-Like Transcription Factor Klf1 Is Required For Optimal Γ- And Β-Globin Expression In Human Fetal Erythroblasts, Divya Vinjamur, Yousef N. Alhashem, Safa Mohamad, Parth Amin, David C. Williams Jr., Joyce A. Lloyd

Human and Molecular Genetics Publications

In human adult erythroid cells, lower than normal levels of Krüppel-like transcription factor 1 (KLF1) are generally associated with decreased adult β- and increased fetal γ-globin gene expression. KLF1 also regulates BCL11A, a known repressor of adult γ-globin expression. In seeming contrast to the findings in adult cells, lower amounts of KLF1 correlate with both reduced embryonic and reduced fetal β-like globin mRNA in mouse embryonic erythroid cells. The role of KLF1 in primary human fetal erythroid cells, which express both γ- and β-globin mRNA, is less well understood. Therefore, we studied the role of KLF1 in ex vivo differentiated …

Novel Osteogenic Ti-6al-4v Device For Restoration Of Dental Function In Patients With Large Bone Deficiencies: Design, Development And Implementation, David J. Cohen, A Cheng, A. Kahn, M. Aviram, Alexander J. Whitehead, Sharon Hyzy, Ryan M. Clohessy, Barbara D. Boyan, Zvi Schwartz

Biomedical Engineering Publications

Custom devices supporting bone regeneration and implant placement are needed for edentulous patients with large mandibular deficiencies where endosteal implantation is not possible. We developed a novel subperiosteal titanium-aluminum-vanadium bone onlay device produced by additive manufacturing (AM) and post-fabrication osteogenic micro-/nano-scale surface texture modification. Human osteoblasts produced osteogenic and angiogenic factors when grown on laser-sintered nano-/micro-textured surfaces compared to smooth surfaces. Surface-processed constructs caused higher bone-to-implant contact, vertical bone growth into disk pores (microCT and histomorphometry), and mechanical pull-out force at 5 and 10 w on rat calvaria compared to non surface-modified constructs, even when pre-treating the bone to stimulate …

24r,25-Dihydroxyvitamin D3 Protects Against Articular Cartilage Damage Following Anterior Cruciate Ligament Transection In Male Rats, Barbara D. Boyan, Sharon L. Hyzy, Qingfen Pan, Kayla M. Scott, Richard D. Coutts, Robert Healey, Zvi Schwartz

Biomedical Engineering Publications

Osteoarthritis (OA) in humans is associated with low circulating 25-hydroxyvitamin D3 [25 (OH)D3]. In vitamin D replete rats, radiolabeled 24R,25-dihydroxyvitamin D3 [24R,25 (OH)2D3] accumulates in articular cartilage following injection of [3 H]-25(OH)D3. Previously, we showed that 24R,25(OH)2D3 blocks chondrocyte apoptosis via phospholipase D and p53, suggesting a role for 24R,25(OH)2D3 in maintaining cartilage health. We examined the ability of 24R,25(OH)2D3 to prevent degenerative changes in articular cartilage in an OAlike environment and the potential mechanisms involved. In vitro, rat articular chondrocytes were treated with IL-1β with and without 24R,25(OH)2D3 or 1α,25(OH)2D3. 24R,25(OH)2D3 but not 1α,25(OH)2D3 blocked the effects of IL-1β …

Mechanical Loading Attenuates Radiation-Induced Bone Loss In Bone Marrow Transplanted Mice, Peter M. Govey, Yue Zhang, Henry J. Donahue

Biomedical Engineering Publications

Exposure of bone to ionizing radiation, as occurs during radiotherapy for some localized malignancies and blood or bone marrow cancers, as well as during space travel, incites dose-dependent bone morbidity and increased fracture risk. Rapid trabecular and endosteal bone loss reflects acutely increased osteoclastic resorption as well as decreased bone formation due to depletion of osteoprogenitors. Because of this dysregulation of bone turnover, bone’s capacity to respond to a mechanical loading stimulus in the aftermath of irradiation is unknown. We employed a mouse model of total body irradiation and bone marrow transplantation simulating treatment of hematologic cancers, hypothesizing that compression …

Intra- And Inter-Fractional Variation Prediction Of Lung Tumors Using Fuzzy Deep Learning, Seonyeong Park, Suk Jin Lee, Elisabeth Weiss, Yuichi Motai

Electrical and Computer Engineering Publications

Tumor movements should be accurately predicted to improve delivery accuracy and reduce unnecessary radiation exposure to healthy tissue during radiotherapy. The tumor movements pertaining to respiration are divided into intra-fractional variation occurring in a single treatment session and inter- fractional variation arising between different sessions. Most studies of patients' respiration movements deal with intra-fractional variation. Previous studies on inter-fractional variation are hardly mathematized and cannot predict movements well due to inconstant variation. Moreover, the computation time of the prediction should be reduced. To overcome these limitations, we propose a new predictor for intra- and inter-fractional data variation, called intra- and …

Postpartum Visit Attendance Increases The Use Of Modern Contraceptives, Saba W. Masho, Susan Cha, Rashel Charles, Elizabeth Mcgee, Nicole Karjane, Linda Hines, Susan G. Kornstein
