The Role of Cognition in Balance Control

Received: 14 September 2023;  Published: 17 February 2024;  doi: 10.21926/obm.neurobiol.2401211

Abstract

Balance is the ability to move and/or preserve a particular position while not falling under external force. Human balance is a complex process of integration and coordination of the sensory, motor, and biomechanical components, which is influenced by intrinsic and exogenous factors. One inherent factor that is hypothesized to have an impact on balance is cognition. However, studies about cognition's role in balance control are still limited, and study literature is needed to gain a better understanding. Cognition [...]

An Exploration of Preschool Teachers’ Perceptions of Physical Activity Integration in a Whole Child Pilot Curriculum

Received: 15 November 2021;  Published: 13 January 2022;  doi: 10.21926/rpn.2201001

Abstract

It is recommended that children ages 3-5 receive 180 minutes of physical activity a day, with at least 60 minutes of moderate-to-vigorous physical activity. Despite these recommendations, a majority of preschoolers are not provided opportunities in the early childhood education setting to meet these daily recommendations through either structured or unstructured physical activity. Accordingly, the number of young children identified as overweight or obese over the past couple of decades has increased. Critical to a [...]

Medawar's Paradox and Immune Mechanisms of Fetomaternal Tolerance

Received: 09 May 2019;  Published: 10 March 2020;  doi: 10.21926/obm.transplant.2001104

Abstract

Brazilian-born British biologist Dr. Peter Medawar played an integral role in developing the concepts of immunologic rejection and tolerance, which led to him receiving the Nobel Prize “for the discovery of acquired immunologic tolerance” and eventually made organ transplantation a reality. However, at the time of his early work in tolerance, a paradox to his theories was brought to his attention; how was pregnancy possible? Pregnancy resembles organ transplantation in that the fetus, possessing paterna [...]

Regulation of Membrane Phospholipid Homeostasis in Neurodegenerative Diseases

Received: 21 December 2020;  Published: 21 July 2021;  doi: 10.21926/obm.geriatr.2103176

Abstract

Neurodegenerative diseases (NDs) are a diverse group of neuropathological diseases that are currently incurable due to the irreversible neuronal loss. At the present rate of the world population growth, it is projected that the number of ND cases will double by the year of 2050. With treatments only available for symptom management and relief, disease prevention may yield significant benefits. Recently, there had been association drawn between the disruption of phospholipid (PL) homeostasis and the progression of N [...]

Immunosuppression in Kidney Transplantation

Received: 19 January 2020;  Published: 03 February 2020;  doi: 10.21926/obm.transplant.2001097

Abstract

Immunosuppressive therapy in renal transplantation is divided into two phases as induction and maintenance therapy. Induction therapy is an intense immunosuppressive therapy administered at the time of kidney transplantation to reduce the risk of acute allograft rejection. In general, induction immunosuppressive strategies utilized by kidney transplant centers fall in one of the two categories. One approach relies upon high doses of conventional immunosuppressive agents, while the other uses antibodies directed aga [...]

The Role of Surveillance Bronchoscopy Following a Lung Transplantation

Received: 01 July 2020;  Published: 21 December 2020;  doi: 10.21926/obm.transplant.2004129

Abstract

Pulmonary transplantation (LuTx) is established as a treatment option for patients with end-stage lung diseases, such as chronic obstructive pulmonary disease, cystic fibrosis, interstitial lung disease, and pulmonary arterial hypertension. Acute rejection and infection are implicated as potential risk factors in developing complications such as bronchiolitis obliterans syndrome (BOS) and chronic rejection, leading to high morbidity and mortality rates after the LuTx. Thus, surveillance procedures after transplanta [...]

Diagnosis and Therapy of Atrial Fibrillation in Geriatric Patients

Received: 16 January 2021;  Published: 28 July 2021;  doi: 10.21926/obm.geriatr.2103178

Abstract

Atrial fibrillation is very common in most old patients who need an adapted therapy due to their comorbidities. Before initiating an antiarrhythmic therapy, possible adverse effects, especially iatrogenic proarrhythmia, and extracardiac side-effects, must be considered. In geriatric patients with atrial fibrillation, heart rate control is the most frequent therapy. Oral anticoagulation plays a vital role in the therapy, but anticoagulation in old patients, who had a bleeding or stroke event, is challenging. Availab [...]

Spotlight on Older Adults in Swallowing Research

Received: 07 November 2020;  Published: 25 December 2020;  doi: 10.21926/obm.geriatr.2004146

Abstract

Generalisations and misconceptions about ageing and swallowing can influence clinical opinion. Assumptions about swallowing function based on someone’s age risk overmedicalising or, conversely, undertreating older patients. Evidence suggests that increased prevalence of swallowing problems in older age is attributed to pathology known to affect swallowing function, or an unrelated serious illness and combination of health factors, and not ageing itself. This review highlights factors clinicians should consider when [...]

Chair Fitness Program for Improved Strength and Physical Function for Older Adults: A Pilot Comparative Effectiveness Study

Received: 05 July 2023;  Published: 12 September 2023;  doi: 10.21926/rpn.2303016

Abstract

Within the US, people are experiencing longer life expectancy, yet these extended lifespans have not necessarily translated into years living in good health. Musculoskeletal degenerative diseases are particularly prevalent amongst older adults. Research shows that regular resistance exercise carries preventive health benefits to combat these conditions. This study evaluated the impact of an innovative hand-held device (OYO) on the physical function of older adults compared to a traditional chair fitness program (CF [...]

Mechanics of ABS Polymer under Low & Intermediate Strain Rates

Received: 24 January 2023;  Published: 16 March 2023;  doi: 10.21926/rpm.2301012

Abstract

Thermoplastics polymers like Acrylonitrile Butadiene Styrene (ABS) are often reinforced with nano/micro reinforcements to enhance their mechanical, thermal and electrical properties. However, the viscoelastic nature of these polymers results in their strong dependence on the applied strain rate and temperature sensitivity, leading to their characterization complexity. Hence it is paramount to study the strain rate-dependent mechanics of neat ABS. In this study, the effect of strain rate and temperature on Young’s m [...]
