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 …

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 …

Macronutrients And Water – Do They Matter In The Context Of Cognitive Performance In Athletes?, Ewa Karpecka, Barbara Fraczek

Baltic Journal of Health and Physical Activity

Proper nutrition is a key factor in physical performance, but there are also indications of an impact of dietary components on the brain function. Therefore, the aim of the study was to assess the impact of macronutrients and water on cognitive performance. Assumptions of the Mediterranean diet correlate with better global cognition, episodic memory, lower risk of cognitive impairment and neurodegenerative diseases. In turn, a high-fat and high-sugar diet shows the opposite effect. Omega-3 fatty acids could be used as a preventive tool for cognitive decline, but there is still insufficient evidence if supplementation improves cognitive functions. The proper intake …
