Abstract

The heart is a vital organ that plays a crucial role in the circulatory system, responsible for pumping oxygen-rich blood and nutrients throughout the body and returning blood containing carbon dioxide to the lungs. Anatomically, the heart consists of four chambers. The coronary vascular system supplies oxygen and nutrients to the heart muscles. The physiology of the heart involves the cycle of heart muscle contraction (systole) and relaxation (diastole), heart rate regulation, and the electrical conduction system that coordinates the heartbeat. Coronary artery disease (CAD) is a disorder of the coronary blood vessels due to atherosclerosis, causing narrowing or blockage of the arteries, hindering blood flow, and leading to ischemia. Prevention of CAD can be done by maintaining a healthy diet, exercising regularly, avoiding smoking, and controlling blood pressure, cholesterol, and blood sugar levels. Understanding the anatomy, physiology, and coronary artery disease is essential for maintaining heart health and preventing cardiovascular disorders.

Abstract

This study aims to examine the role of biochemistry in the processing of functional foods and its impact on the nutritional content and bioactive compounds. The method used is a literature review, collecting and analyzing relevant literature on biochemistry, food processing, and functional foods. The results show that biochemical processes, such as fermentation and heating, can affect the nutritional content of food. Fermentation can increase the content of probiotics and unsaturated fatty acids that are beneficial for health, while excessive heating can damage sensitive compounds like vitamin C. Proper processing can enhance the bioavailability of bioactive compounds, thus optimizing the health benefits of functional foods. The conclusion of this study emphasizes the importance of understanding biochemical processes in food processing to maximize health benefits.

Abstract

Antibiotic resistance has emerged as one of the most critical challenges in modern healthcare. Pathogenic bacteria that were once susceptible to antibiotics have developed survival mechanisms, making infections increasingly difficult to treat. Understanding and combating this issue requires advanced tools, with microscopy playing a pivotal role. Microscopes enable researchers to observe bacterial morphological changes, biofilm formation, and antibiotic-bacteria interactions at molecular levels. Various microscopy techniques – including light microscopy, electron microscopy, and fluorescence microscopy – have significantly contributed to both research and clinical diagnostics. Through a literature review approach, this article examines how microscopy facilitates antibiotic resistance studies and supports the development of more effective treatment strategies.
