Can Physical Activity Modulate Pain Perception During Ontogenesis?, Maciej Pawlak, Aleksandra Jazdzewska, Katarzyna Leznicka

Baltic Journal of Health and Physical Activity

The aim of the paper is to emphasise the significance of physical activity as an element directly or indirectly modulating the perception of pain during ontogenesis. Pain is a distinctive sensory sensation and also a subjective criterion of health or disease. In contrast to other modalities (taste, smell, touch), it triggers solely negative emotions and sensations. Pain is a highly individualised sensory phenomenon, involving the physical, cognitive and emotional spheres of human life. Different reactions to pain during ontogeny most often result from the loss of communication skills, a systematic decrease in the functions of all systems and organs, in …

Antibacterial Activity, Structure-Activity Relationships, And Scale-Up Reaction Of 1,3,4-Oxadiazoles, Olivia Marie Smith

Undergraduate Honors Thesis Projects

Oxadiazoles are compounds in the field of organic chemistry that have been gathering interest in the medicinal chemistry and microbiology communities for their biological properties, which range from anti-inflammatory agents, to chemotherapy drugs, to antibiotics. The synthesis of oxadiazoles can be difficult due to the expensive and complex nature of the techniques used as well as the volatile reagents and elevated temperatures that are often required in organic synthesis. The Grote lab has recently developed a new method for the synthesis of 1,3,4-oxadiazoles under mild conditions. The goals of this thesis were thus twofold: to develop a viable scale-up procedure …

Inhibition Of Nuclear Transport Of Perilipin 5, Hope Lewis

Undergraduate Honors Thesis Projects

Obesity, type II diabetes mellitus, and non-alcoholic fatty liver disease are all conditions related to aberrant lipid storage in humans. Nearly all cells have the capacity to store neutral lipids in lipid storage droplets, organelles that regulate the storage of their hydrophobic contents. All lipid storage droplets are coated with at least one member of the perilipin family of proteins. Perilipin 5 is expressed in oxidative tissues including oxidative muscleand fasted liver and has been shown to play important roles in neutral lipid metabolism in these tissues. Perilipin 5’s involvement in gene expression was discovered during catecholamine-stimulated lipolysis, where the …

Northwest Journal of Teacher Education

Before the COVID-19 pandemic changed the educational landscape, students with disabilities, especially those who are culturally and linguistically diverse, and their special education teachers who worked and attended schools located in rural communities faced barriers most schools and communities experienced nationwide. As schools shifted to remote virtual learning due to the COVID-19 pandemic, rural schools were already at a disadvantage with the lack of resources with technology access. The call for addressing shortcomings in the various digital technology supports towards enhancing the teachers’ delivery of content and the students’ academic outcomes has been a continual challenge to address. This paper …

Deviant Behaviour In Competitive Sport. A Sociological Attempt At Explaining The Phenomenon, Zbigniew Dziubinski

Baltic Journal of Health and Physical Activity

This article seeks to use selected sociological theories to account for the phenomenon of deviance in sport. Two main theoretical approaches are employed herein: the functionalist/structuralist approach and symbolic interactionism. The analysis that follows leads to the conclusion that deviance which occurs in sport is predominantly a consequence of deviance in modern societies. Sport, in turn, is just a convenient area for deviant behaviours to be manifested, which often happens more clearly and conspicuously than in societies.

Different Forms Of Swimmers’ Final Weeks Pre-Competition Preparation, Kamil Sokolowski, Marek Strzala, Arkadiusz Stanula

Baltic Journal of Health and Physical Activity

The pre-competition training phase is a period that precedes the main competition. Combined training phases of overload training (OT) and taper (TP) create the most popular pattern of final form preparation among the swimmers despite the methodology difficulties faced by coaches. In the IPC, the duration and training load were strictly set. The main purpose of training in the IPC is to cause a substantial supercompensation effect by the high volume and capacity of the training. However, high volume and intensity fluctuations typical of the IPC may cause performance regression due to overtraining and exhaustion. The main aim of the …

The Application Of Bone Morphogenetic Proteins In Medicine, Dentistry, Sport And Rehabilitation: A Review Of Literature, Aleksandra Jaron, Elzbieta Grzywacz, Natalia Kerber-Wyka, Sara Zacharska, Michal Lobacz, Grzegorz Trybek

Baltic Journal of Health and Physical Activity

Bone tissue is a mineralized structure with a complicated metabolism and due to its mechanical functions its structure must be adapted to the bone function. The BMP protein group stimulates the formation of bone and cartilage and influences numerous non-osteogenic processes. As a result of their osteogenic effect, BMP proteins are used in numerous areas of medicine, including dentistry and orthopaedics, as well as sport and rehabilitation. The publications used in this paper were sourced from the PubMed and the Google Scholar databases. The index entries used to search the databases included BMP, bone morphogenetic proteins, medicine, dentistry and sport. …

Exercise − A Unique Endogenous Regulator Of Irisin, Bdnf, Leptin And Cortisol Against Depression, Gilmara Gomes De Assis, Pawel Cieszczyk

Baltic Journal of Health and Physical Activity

Depression is the most prevalent stress-related disorder affecting the population world-wide with potential for an eminent increase after the 2020 pandemic. The mechanisms through which metabolism is involved in depression and stress disorders have been extensively investigated. However, their assessment using exogenous measures is a current limitation. Exercise, as is well reported in animal studies, exerts a critical regulatory influence on the main factors known to participate in these mechanisms. This overview describes the role of cortisol, leptin, irisin and BDNF in the exercise physiology and the known mechanism through which these factors act in anti-depressant mechanisms. Furthermore, the exercise …

Critical-Thinking Experiences Of Chinese And U.S. College Students: A Comparative Analysis Using Phenomenology, Lu (Wendy) Yan

The Qualitative Report

In this study, I investigated the critical-thinking experiences of seven Chinese international and five U.S. students attending a large public university in the United States. I conducted a comparative analysis of these groups’ different experiences with critical thinking in this context, while closely following the twin methods of epoché and reduction in phenomenology to remain attuned to any personal biases. My results indicated that Chinese and U.S. students experienced critical thinking differently on the basis of the four universal existentials noted by van Manen (2016): lived experiences of relation (self–other), materiality (things), time, and space/place. Specifically, the Chinese students tended …
