Prioritizing Indigenous Participation And Compensation In Research, Amanda Sabin Feb 2024

Prioritizing Indigenous Participation And Compensation In Research, Amanda Sabin

Journal of Critical Global Issues

Throughout history, the dynamic between colonial entities and indigenous groups has been characterized by exploitation and power imbalance. Indigenous knowledge has the potential to positively impact the world, through medicinal breakthroughs, radical approaches to sustainability, cultural heritage, systems of learning and adaptation, and more. Particularly in the context of research, fields like anthropology, botany and pharmacology serve to benefit from indigenous knowledge, but these interactions cannot continue to be based on extraction at the cost of indigenous communities. This work will discuss the future of relationships between researchers and indigenous communities; how this power dynamic must be transformed into an …


Integrating Cannabis Education Into The Athletic Training Curriculum, Jeff G. Konin, Jimmy Onate Feb 2024

Integrating Cannabis Education Into The Athletic Training Curriculum, Jeff G. Konin, Jimmy Onate

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Context. Cannabis has become more prevalent in society and requires greater knowledge on the part of the athletic trainer. Objective. The purpose of this paper is to provide a framework for recognizing how cannabis education can be integrated into the athletic training curriculum utilizing the existing accreditation standards. Background. For decades the use of cannabis has been illegal. Athletes who were caught with cannabis in their system were penalized by their respective e sport organization body. During the past decade in the United States the federal government has moved toward decriminalization and expungement for those found with and …

Vkorc1 Polymorphisms And Complete Resistance To Vitamin K Antagonists: About Two Cases., Ilham Benyamna, Houda El Fissi, Fadoua Bouzid, Abdelhamid El Mousadik, Najat Alif

BioMedicine

Complete resistance to vitamin K antagonists is a rare but serious. It can complicate therapeutic management, especially when direct oral anticoagulants cannot be used. Some single mutations in the VKORC1 gene have been identified in patients partially or completely resistant to vitamin K antagonists. We report the cases of two women in their fifties who presented an unexplained peripheral venous thrombosis. The aetiological assessment did not show any abnormalities. Genetic testing showed that both patients had the VKORC1 5417GG genotype. The VKORC1 3673 genotype was GG in case 1 and GA in case 2. The two patients showed complete resistance …

Computational Analysis Of Dimer G6pd Structure To Elucidate Pathogenicity Of G6pd Variants, Shamini Chandran, Naveen Eugene Louis, Syazwani Itri Amran, Nurriza Ab Latif, Muaawia Ahmed Hamza, Mona Alonazi

BioMedicine

An inherent genetic enzyme disorder in humans, known as glucose-6-phosphate dehydrogenase (G6PD) deficiency, arises due to specific mutations. While the prevailing approach for investigating G6PD variants involves biochemical analysis, the intricate structural details remain limited, impeding a comprehensive understanding of how different G6PD variants of varying classes impact their functionality. This study examined the dynamic properties of G6PD wild types and six G6PD variants from different classes using molecular dynamic simulation (MDS). The wild-type and variant G6PD structures unveil high fluctuations within the amino acid range of 274-515, the structural NADP+ binding site, pivotal for enzyme dimerization. Specifically, two …

Biomedicines In Longevity And Aging The Quest To Resist Biological Decline, Raymond D D Raymond Feb 2024

Biomedicines In Longevity And Aging The Quest To Resist Biological Decline, Raymond D D Raymond

BioMedicine

Aging is considered part of the natural process of life, however in recent years medical literature has started to show that specific facets of aging are beginning to be understood and those specific factors may even be considered preventable with various measures as this paper will demonstrate. Aging is also considered the number one cause of poor quality of life, disease, disability, and death, so the importance of understanding the aging process and how to control certain aspects of it cannot be underestimated when age related suffering is factored in. The causes of aging are now becoming well understood, and …

Strengthening First Responders’ Coaching Proficiency Through A Peer Fitness Leader Workshop: A Preliminary Efficacy Trial, Sarah N. Lanham, Thomas R. Nagel, Haresh Rochani, Bridget F. Melton, Richard E. Cleveland

International Journal of Exercise Science

International Journal of Exercise Science 17(3): 298-307, 2024. First responders require physical fitness to perform dangerous tasks in unpredictable environments. To promote physical fitness among first responders, many agencies use a peer fitness leader (PFL) approach; however, resources for the fitness, wellness, and health of PFLs are often minimal. This study’s purpose was to investigate the effectiveness of a training workshop to increase PFL’s training knowledge and coaching comfort (CC). Thirty-six PFLs (Experience: 14.6 ± 9.1 yrs; Age: 41.0 ± 9.8 yrs; BMI: 28.9 ± 7.0 kg·m-2) attended a one-day workshop. Paired samples t-tests assessed for differences …

Gender medicine is a multidisciplinary science and represents an important perspective for pathophysiological and clinical studies in the third millennium. Here, it is provided an overview of the topics discussed in a recent course on the Role of Sex and Gender in Ageing and Longevity. The paper highlights three themes discussed in the course, i.e., the interaction of gender/sex with, i) the pathophysiology of age-related diseases; ii), the role of genetics and epigenetics in ageing and longevity and, iii) the immune responses of older people to pathogens, vaccines, autoantigens, and allergens. Although largely unexplored, sex and gender are modulators …

Effect Of Rainfall Pattern On Sediment Yield And Runoff In Different Textured Soils, Abdul-Rahman Perdawood Haydar, Kamyar Mutalib Mohammed, Dawod Rasooli Keya

Polytechnic Journal

Evaluating the impacts of rainfall intensities on bulk density, runoff rate, and sediment yield is critical in soil characterization and sediment transport. The primary objective of this research is to use multiple linear regression analysis to establish several models correlating rainfall intensity, silt content, and clay content with bulk density, sediment yield, and runoff rate. Several soil samples from different locations in Erbil, Iraq, were collected. Soil samples were placed in a rainfall simulator and brought back to in-situ conditions. The parameters of the suggested models for predicting bulk density, runoff rate, and sediment yield were estimated using linear and …

Investigations Of The Eutectic Formation And Skin Rejuvenation By Hyaluronan - Kojic Acid Dipalmitate System, Syed Waqar Hussain Shah, Sumbal Imran, Iram Bibi, Kashif Ali, Nadia Bashir

Karbala International Journal of Modern Science

Eutectic phenomenon has been investigated in binary system based on biopolymer hyaluronan (HN) and kojic acid dipalmitate (KAD). Solid-liquid phase diagram showed a significant dependence of melting points on weight fraction of KAD up to KAD < 0.5. A negligible regain to melting temperature of pure KAD occurred later. Simulations of molecular mechanics using a four-unit segment of HN and KAD revealed the interaction between carbonyl of KAD with 4-OH on N-acetylglucosamine unit of oligomer. Infrared vibrational spectroscopy also endorsed the existence of a weakly interacting system. Such behavior was expected due to steric hinderance and rigidity of biopolymer. The thermal decomposition temperature of HN (i.e., 215 °C) was increased to 322 °C in HK50 having HN and KAD in 1:50 w/w. Bioelectric impedance analysis revealed that these green materials could promote skin health in humans.
