Challenge In Diagnosis And Management Of Lentigo Maligna And Lentigo Maligna Melanoma, Ika Anggraini, Elisa Miranda, Larisa Paramitha Wibawa, Roro Inge Ade Krisanti, Adhimukti T. Sampurna

Journal of General - Procedural Dermatology and Venereology Indonesia

Lentigo maligna (LM) is a subtype of melanoma in situ, which can evolve into lentigo maligna melanoma (LMM) if treated inadequately. LM and LMM are usually found on chronically sun damaged skin such as the face (cheek and nose) of the elderly on seventh or eight decades. Clinical manifestation of LM may be quite subtle, so early diagnosis is difficult to perform.The treatment of LM and LMM are challenging due to ill-defined clinical margin, predilection on the face with great size, and preponderance of the elderly, which are potential for recurrency and progressiveness from LM into LMM.

Anatomy and Cell Biology Publications

Background: Epithelial ovarian cancer exhibits extensive interpatient and intratumoral heterogeneity, which can hinder successful treatment strategies. Herein, we investigated the efficacy of an emerging oncolytic, Maraba virus (MRBV), in an in vitro model of ovarian tumour heterogeneity. Methods: Four ovarian high-grade serous cancer (HGSC) cell lines were isolated and established from a single patient at four points during disease progression. Limiting-dilution subcloning generated seven additional subclone lines to assess intratumoral heterogeneity. MRBV entry and oncolytic efficacy were assessed among all 11 cell lines. Low-density receptor (LDLR) expression, conditioned media treatments and co-cultures were performed to determine factors impacting MRBV oncolysis. …

Psychological Well-Being’S Link With Cardiovascular Health In Older Adults, Julia K. Boehm, Jackie Soo, Ying Chen, Emily S. Zevon, Rosalba Hernandez, Donald Lloyd-Jones, Laura D. Kubzansky

Psychology Faculty Articles and Research

Introduction

Favorable cardiovascular health (FCH) is associated with healthy longevity and reduced cardiovascular mortality risk. However, limited work has investigated the distribution of FCH in older age or considered the antecedents of FCH. Based on prior work linking psychological well-being with cardiovascular endpoints, higher psychological well-being was hypothesized to be associated with increased likelihood of maintaining FCH over time.

Methods

Data were from the English Longitudinal Study of Ageing. The first study wave (2002–2003) included men and women aged ≥50 years. The analytic sample (N=4,925) was restricted to individuals without baseline cardiovascular disease and with clinical data from three follow-ups …

MaineHealth Maine Medical Center

To avoid delays in the availability of compatible blood for elective surgery patients requiring transfusion, a type and screen specimen should be completed at least 24 hours prior to surgery. Baseline metrics in an acute care inpatient blood bank demonstrated a significant number of cases with no type or screen completed.

The objective of this KPI was to prevent any delays in providing compatible blood products to scheduled surgical patients. Several internal and external system issues were identified as a result of a root cause analysis and a number of actions were initiated.

Outcomes have been positive. Data collection post …

Understanding The Chondrogenic Potential Of Articular Chondrocytes, Krishna Sarma

Theses & Dissertations

Articular cartilage is a smooth, visco-elastic, aneural, avascular tissue made of water, an exquisitely organized framework of proteoglycans, glycosaminoglycans, and collagen fibrils and articular chondrocytes. It’s beautiful organization and composition provide it with the flexibility and strength to cover, protect and lubricate the ends of long bones in a diarthrodial joint. Cartilage homeostasis relies on articular chondrocytes to translate the mechanical forces of daily activity into efficient remodeling of the extracellular matrix. Age, joint injury, or other insulting factors can progressively incapacitate articular chondrocytes, resulting in cartilage lesions that devolve to degenerative joint disease. Therefore, the central idea explored in …

Maternal Intuition Of Fetal Gender, Michael Mcfadzen, David P. Dielentheis, Ronda Kasten, Maharaj Singh, Joe Grundle

Journal of Patient-Centered Research and Reviews

Purpose: Fetal gender speculation is a preoccupation of many expecting parents, and pregnant women commonly profess to intuitively know the gender of their unborn babies. This study objectively compared pregnant mothers’ perceptions of fetal gender to sonographically proven gender determinations. Also, success rates from previously published studies, noninvasive prenatal testing and a myriad of gender determination methods were observed and reported for context.

Methods: All pregnant women presenting for second-trimester screening ultrasound (at 17–23 weeks gestation) in the obstetrics department of a single health center were asked to participate. A medical sonographer described the ultrasound examination, obtained appropriate consent and …

Body Size Predicts Cardiac And Vascular Resistance Effects On Men's And Women's Blood Pressure, Joyce M. Evans, Siqi Wang, Christopher Greb, Vladimir Kostas, Charles F. Knapp, Qingguang Zhang, Eric S. Roemmele, Michael B. Stenger, David C. Randall

Biomedical Engineering Faculty Publications

Key Points Summary

• We report how blood pressure, cardiac output and vascular resistance are related to height, weight, body surface area (BSA), and body mass index (BMI) in healthy young adults at supine rest and standing.
• Much inter-subject variability in young adult's blood pressure, currently attributed to health status, may actually result from inter-individual body size differences.
• Each cardiovascular variable is linearly related to height, weight and/or BSA (more than to BMI).
• When supine, cardiac output is positively related, while vascular resistance is negatively related, to body size. Upon standing, the change in vascular resistance is positively related to size. …

Malignant Hyperthermia, Brandon Kinnamon

Nursing Student Class Projects (Formerly MSN)

Common anesthetic agents can trigger a pathological response in patients resulting in intracellular calcium release and hyper-metabolism. This condition is known as Malignant Hyperthermia (MH). It is vital for anesthesia professionals and critical care nurses to recognize MH and act quickly to limit rapid shifts of electrolytes which can ultimately lead to death. As soon as cardinal signs of malignant hyperthermia are identified, the medication dantrolene should be administered along with intensive nursing care. Significant signs and symptoms, the pathophysiology of MH, and implications for nursing care are all examined in greater detail.

Increased Expression Of The Tight Junction Protein Tjp1/Zo-1 Is Associated With Upregulation Of Taz-Tead Activity And An Adult Tissue Stem Cell Signature In Carfilzomib-Resistant Multiple Myeloma Cells And High-Risk Multiple Myeloma Patients, Irene Riz, Robert G. Hawley

Anatomy and Regenerative Biology Faculty Publications

Tight junction protein 1 (TJP1) has recently been proposed as a biomarker to identify multiple myeloma (MM) patients most likely to respond to bortezomiband carfilzomib-based proteasome inhibitor regimens. Herein we report increased expression of TJP1 during the adaptive response mediating carfilzomib resistance in the LP-1/Cfz MM cell line. Moreover, increased TJP1 expression delineated a subset of relapsed/refractory MM patients on bortezomib-based therapy sharing an LP-1/Cfzlike phenotype characterized by activation of interacting transcriptional effectors of the Hippo signaling cascade (TAZ and TEAD1) and an adult tissue stem cell signature. siRNA-mediated knockdown of TJP1 or TAZ/TEAD1 partially sensitized LP-1/Cfz cells to carfilzomib. …

Lessons To Be Learned: How A Comprehensive Neurobiological Framework Of Atypical Reading Development Can Inform Educational Practice, Ola Ozernov-Palchik, Xi Yu, Yingying Wang, Nadine Gaab

Center for Brain, Biology, and Behavior: Faculty Publications

Dyslexia is a heritable reading disorder with an estimated prevalence of 5–17%. A multiple deficit model has been proposed that illustrates dyslexia as an outcome of multiple risks and protective factors interacting at the genetic, neural, cognitive, and environmental levels. Here we review the evidence on each of these levels and discuss possible underlying mechanisms and their reciprocal interactions along a developmental timeline. Current and potential implications of neuroscientific findings for contemporary challenges in the field of dyslexia, as well as for reading development and education in general, are then discussed.

Biomechanical Testing Of An Exercise For Strengthening The Proximal Femur., Alyssa Osbourne

Electronic Theses and Dissertations

Based on the principles of cutting edge bone remodeling research, a unique therapeutic exercise device was designed specifically to improve bone quality at the most critical location of the proximal femur prone to fracture: the superior-lateral femoral neck where the fracture first initiates during a fall. The exercise/device is intended to work by inducing enough strain in the bone to stimulate the body’s natural bone remodeling mechanisms to increase bone density in the proximal femur and consequently prevent a fracture from arising if a fall to the side does occur.

In order to test the proposed exercise, experiments simulating the …

Center for Microelectrode Technology Faculty Publications

Spreading depolarization (SD) is a slow propagating wave of strong depolarization of neural cells, implicated in several neuropathological conditions. The breakdown of brain homeostasis promotes significant hemodynamic and metabolic alterations, which impacts on neuronal function. In this work we aimed to develop an innovative multimodal approach, encompassing metabolic, electric and hemodynamic measurements, tailored but not limited to study SD. This was based on a novel dual-biosensor based on microelectrode arrays designed to simultaneously monitor lactate and glucose fluctuations and ongoing neuronal activity with high spatial and temporal resolution. In vitroevaluation of dual lactate-glucose microbiosensor revealed an extended linear range, …

Local Anesthesia Toxicity, Nicole Mccleery

Nursing Student Class Projects (Formerly MSN)

Local anesthesia (LA) provides a way to relieve temporary pain in a small part of the body and has been used for over 100 years (Fencl, 2015). LA also prevents the passage of surgical stimuli into the central nervous system (CNS) making a surgical procedure less painful for the patient (Noble, 2015). According to Noble, “altering the passage of stimuli from smaller diameter neurons in a confined area with lower drug dosages is called LA, such as the injection of LA around a surgical incision” (Noble, 2015, p.325). LA can be used in a variety of settings, such as in …

Osteopontin Is Linked With Akt, Foxo1, And Myostatin In Skeletal Muscle Cells, Peter P. Nghiem, Joe N. Kornegay, Kitipong Uaesoontrachoon, Luca Bello, Ying Yin, Akanchha Kesari, Priya Mittal, Scott J. Schatzberg, Gina M. Many, Norman H. Lee, Eric P. Hoffman

All Faculty Scholarship for the College of the Sciences

Introduction: Osteopontin (OPN) polymorphisms are associated with muscle size and modify disease progression in Duchenne muscular dystrophy (DMD). We hypothesized that OPN may share a molecular network with myostatin (MSTN).

Methods: Studies were conducted in the golden retriever (GRMD) and mdx mouse models of DMD. Follow-up in-vitro studies were employed in myogenic cells and the mdx mouse treated with recombinant mouse (rm) or human (Hu) OPN protein.

Results: OPN was increased and MSTN was decreased and levels correlated inversely in GRMD hypertrophied muscle. RM-OPN treatment led to induced AKT1 and FoxO1 phosphorylation, microRNA-486 modulation, and decreased MSTN. An AKT1 inhibitor …

Antimicrobial Hydroxyapatite-Gelatin-Silica Composite Pastes With Tunable Setting Properties, Vuk Uskoković, Shreya Ghosh, Victoria M. Wu

Pharmacy Faculty Articles and Research

Bone grafting is one of the commonest surgical procedures, yet all bone substitutes developed so far suffer from specific weaknesses and the search for a bone graft material with ideal physical and biological properties is still ongoing. Calcium phosphate pastes are the most frequently used synthetic bone grafts, yet they (a) often take an impractically long time to set, (b) release the drug content too fast, and (c) do not form pores large enough to accommodate host cells and foster osseointegration. To make up for these deficiencies, we introduced gelatin and silica to pastes composed of 5–15 nm sized hydroxyapatite …

Differential Requirement For Satellite Cells During Overload-Induced Muscle Hypertrophy In Growing Versus Mature Mice, Kevin A. Murach, Sarah H. White, Yuan Wen, Angel Ho, Esther E. Dupont-Versteegden, John J. Mccarthy, Charlotte A. Peterson

Physical Therapy Faculty Publications

Background: Pax7+ satellite cells are required for skeletal muscle fiber growth during post-natal development in mice. Satellite cell-mediated myonuclear accretion also appears to persist into early adulthood. Given the important role of satellite cells during muscle development, we hypothesized that the necessity of satellite cells for adaptation to an imposed hypertrophic stimulus depends on maturational age.

Methods: Pax7^CreER-R26R^DTA mice were treated for 5 days with vehicle (satellite cell-replete, SC+) or tamoxifen (satellite cell-depleted, SC-) at 2 months (young) and 4 months (mature) of age. Following a 2-week washout, mice were subjected to sham surgery or 10 day …

Measuring The Energy Of Ventilation And Circulation During Human Walking Using Induced Hypoxia, Masahiro Horiuchi, Yoshiyuki Fukuoka, Yoko Handa, Daijiro Abe, Herman Pontzer

Publications and Research

Energy expenditure (EE) during walking includes energy costs to move and support the body and for respiration and circulation. We measured EE during walking under three different oxygen concentrations. Eleven healthy, young, male lowlanders walked on a treadmill at seven gait speeds (0.67–1.83 m s−1) on a level gradient under normobaric normoxia (room air, 21% O2), moderate hypoxia (15% O2), and severe hypoxia (11% O2). By comparing the hypoxia-induced elevation in heart rate (HR [bpm]), ventilation (VE [L min−1]) with the change in energy expenditure (EE [W]) at each speed, we were able to determine circulatory and respiratory costs. In …

Germ-Line Gene Editing And Congressional Reaction In Context: Learning From Almost 50 Years Of Congressional Reactions To Biomedical Breakthroughs, Russell A. Spivak, J.D., I. Glenn Cohen, J.D., Eli Y. Adashi, M.D., M.S.

Journal of Law and Health

On December 18, 2015, President Obama signed into law a policy rider forestalling the therapeutic modification of the human germ line. The rider, motivated by the science’s potential unethical ends, is only the most recent instance in which the legislature cut short the ongoing national conversation on the acceptability of a developing science. This essay offers historical perspective on what bills were proposed and passed surrounding four other then-developing scientific breakthroughs—Recombinant DNA, in vitro fertilization, Cloning, Stem Cells—to better analyze how Congress is, and should, regulate this exciting and promising science.

Characterization Of Transmembrane Protein 35 Expression: Considerations Of Sex And Ovarian Hormones, Amanda M. Vanderplow

All NMU Master's Theses

The recently discovered novel neuropeptide transmembrane protein 35 (TMEM35), is believed to modulate chemical signaling within the nervous system. Notably, the TMEM35 protein is detectable in humans, non-human primates and rodents, suggesting a conserved and critical function. Despite this, the functions of TMEM35 are ill-defined in the nervous system and insufficiently studied (currently only three publications). Previous work has identified high expression of TMEM35 in both the ventromedial hypothalamus (VMH) and the limbic circuit of the mouse brain. Due to the known functions of these two regions, this pattern of expression indicates possible roles of this neuropeptide in social behavior …
