A Call to Arms for the Aged Care Sector: A Spotlight on Systematic Abuse and Neglect of Older Disabled Persons

Received: 17 July 2018;  Published: 28 November 2018;  doi: 10.21926/obm.geriatr.1804022

Abstract

With rapidly aging populations worldwide there will be an increasing need to focus attention on the expected increase in disability with advancing age. Drawing upon established literature this paper aims to highlight the contribution of anthropology including selected research findings and contemporary understandings surrounding ageism, abuse and exploitation of older disabled persons. Health care providers within the context of the aged care sector are challenged to unburden themselves with negative images and pra [...]

The Effect of Rotor Radius Ratio on The Performance of Hybrid Vertical Axis Wind Turbine Savonius-Darrieus NREL S809

Received: 05 October 2022;  Published: 02 January 2023;  doi: 10.21926/jept.2301001

Abstract

This research aims to know the effect of the Rotor Radius Ratio on the performance of the hybrid Vertical Axis Wind Turbine Savonius-Darrieus NREL S809 model using the Computational Fluid Dynamics method. Two-bladed Savonius is used as an internal rotor, and three-bladed Darrieus NREL S809 as an external rotor. Turbine model performance is analyzed through the value of the Moment Coefficient and Power Coefficient. The result shows that the increase in the Rotor Radius Ratio value causes an increase in the initial M [...]

A Computational Simulation Technology for Specific Counting of Perinatal and Postnatal Human Tissue Stem Cells for Transplantation Medicine

Received: 22 April 2020;  Published: 28 August 2020;  doi: 10.21926/obm.transplant.2003117

Abstract

Although tissue stem cells are essential for the maintenance, renewal, and repair of vertebrate organs and tissues, previously, the simple act of counting them has not been possible. For more than a half-century, progress in tissue stem cell research and medicine has been undermined by the lack of a means to determine tissue stem cell number. In particular, a major unmet need for stem cell transplantation medicine has been a way to quantify the specific dosage of tissue stem cell treatments. The counting problem pe [...]

Aqueous Lithium--Air Batteries with High Power Density at Room Temperature under Air Atmosphere

Received: 30 June 2021;  Published: 23 September 2021;  doi: 10.21926/jept.2103041

Abstract

Rechargeable batteries with higher energy and power density exceeding the performance of the currently available lithium-ion batteries are suitable for application as the power source in electric vehicles (EVs). Aqueous lithium-air batteries are candidates for various EV applications due to their high energy density of 1910 Wh kg-1. The present study reports a rechargeable aqueous lithium-air battery with high power density at room temperature. The battery cell comprised a lithium anode, a non-aqueous anode electro [...]

Examining the Social Signaling and Person Perception Functions of Loneliness

Received: 07 January 2022;  Published: 19 April 2022;  doi: 10.21926/obm.neurobiol.2202119

Abstract

Loneliness is a common condition that poses substantial risks to morbidity and mortality. Cacioppo and Cacioppo’s [1] evolutionary theory of loneliness (ETL) provides that loneliness serves a social signaling function and also manifests in hypervigilance to threat, which we propose can influence person perception. In this experiment, 480 observers evaluated videotaped self-presentation messages from speakers who scored either high or low on a measure of loneliness. On the basis of ETL, we hypothesized that observer [...]

Role of Procalcitonin in Management of Infection in Solid Organ Transplantation Recipients: Review

Received: 23 December 2018;  Published: 01 March 2019;  doi: 10.21926/obm.transplant.1901054

Abstract

Infections are a common cause of morbidity and mortality in solid organ transplantation (SOT) recipients. Procalcitonin (PCT) has garnered attention as an inflammatory marker that has been shown to be a valuable marker for early identification of systemic bacterial infection. However, interpretation of PCTs value in the different types of infections, transplanted organs, and post-operative courses can be challenging. We review the role of PCT in the management of infections in SOT recipients. First, the PCT level c [...]

4D Printed Shape Memory Polymers: Morphology and Fabrication of a Functional Antenna

Received: 17 February 2022;  Published: 29 April 2022;  doi: 10.21926/rpm.2202009

Abstract

Shape memory polymers (SMPs) are smart materials that can respond to certain thermal, chemical or electrical stimuli by inducing a structural conformation change into a temporary shape. In this work, a 3D printing process based on a Vat Photo-polymerization of a shape memory polymer (SMP) was investigated to produce customized smart and complex morphable antennas. The mechanical and material properties were examined through a tensile, flexural and rheological testing for different polymer mixture ratios. It was obs [...]

Live-Born Double Aneuploidy at the Johns Hopkins Cytogenomics Laboratory: Case Report and Review of the Literature

Received: 30 June 2022;  Published: 07 November 2022;  doi: 10.21926/obm.genet.2204168

Abstract

Double aneuploidy is the co-occurrence of aneuploidy of two different chromosomes within the same individual. Genomic imbalance associated with two aneuploidies in humans is associated with early lethality, and observation in live-born humans is rare. In isolation, trisomy of chromosomes 13, 18, 21, X, and Y may be better tolerated, whereas monosomy of X is the only such type of aberration that may be compatible with life. It is hypothesized that two successive malsegregation events must occur in early development [...]

Special Issue: Treatment of Genetic Disease

Received: 18 January 2018;  Published: 31 January 2018;  doi: 10.21926/obm.genet.1801012

Abstract

With the increasing ability to control infectious and nutritional diseases in developed countries, there has come the realization that genetic and epigenetic regulation in diseases are a major cause of disability, death, and human tragedy. Here, I discuss current knowledge about this matter including the diagnosis, counseling, treatment and management as well as some current therapeutic interventions such as gene, stem cell, epigenetic therapies and future directions in the field.

Enhancing Thermal, Viscoelastic, and Mechanical Properties of Silicone Rubber Matrix through Reinforcements for Use as a Medical Implant

Received: 14 December 2023;  Published: 03 May 2024;  doi: 10.21926/rpm.2402011

Abstract

The use of silicone rubber as an implant is limited due to its weak properties. In this study, the impact of various reinforcements, such as TiO2 or SiO2 nanoparticles, carbon, or polypropylene fiber micro reinforcements, on the mechanical, thermal, and viscoelastic properties of silicone rubber composites with RTV-4125 matrix was investigated. The composites were evaluated through several tests, including tensile, compression, FTIR, TGA, DMTA, and water adsorption tests. It was found that the composites' tensi [...]
