Male hormones and the probability of mortality
The role of hormonal balance in men’s health is particularly important, especially for the older age group. As men age, hormonal changes in their bodies can affect their health and life expectancy. Sex hormones, such as testosterone and estradiol, play a key role in the development of cardiovascular disease-related risks. These hormones not only influence reproductive health but also impact the functioning of the cardiovascular system. In men, changes in hormonal levels can lead to various health problems, many of which are among the leading causes of death. Scientific research continuously seeks to understand how sex hormones influence mortality rates and how they relate to cardiovascular diseases. Recent studies shed…

The Post-Mortem State: The Role of Cadavers in Medical Education
A dissection, as an integral part of medical training, has always played a central role in medical education. A detailed understanding of the human body is essential for doctors, as the foundation of healing activities is a thorough knowledge of the body’s structure and function. The dissection of cadavers provides an opportunity for future doctors to study the complexity of human anatomy in real conditions. While modern technology and computer models continue to evolve, the direct experience that dissection offers is still irreplaceable. The donation of cadavers for medical training is a sensitive and respectful decision that must take into account legal and ethical considerations. Various regulations provide opportunities for…

The Genetic Basis of Parkinson’s Disease
A Parkinson’s disease is a neurodegenerative disorder that affects many people worldwide. Symptoms include movement coordination difficulties, tremors, and stiffness, which significantly complicate daily life. The exact causes of the disease are not yet fully understood, but researchers are increasingly focusing on the role of genetic factors. Recent scientific studies have also revealed that mutations in certain genes may increase the risk of developing Parkinson’s disease. The aim of genetic research is to better understand the background of the disease, while also providing opportunities to develop new treatment methods. The latest studies have analyzed the genetic material of thousands of individuals, including those suffering from Parkinson’s disease and healthy control…

Have the genes that cause ovarian cancer been discovered?
Ovarian cancer is a disease that can manifest in various forms, and researchers are continuously searching for the causes of its development. According to the latest scientific discoveries, certain genetic mutations play a key role in the development of an aggressive type of the disease, clear cell ovarian cancer. Such research not only aids in understanding the disease but also creates opportunities for the development of new treatment methods. In genetic research, scientists are gaining more and more information about the mechanisms behind cancer diseases. Among these discoveries is the work of a research group at Johns Hopkins University, which identified two key genes that may play a role in…

Recent Research Findings on Ear Function
The functioning of the ear and the perception of sounds have always fascinated the scientific community. Over the past decades, continuous discoveries have emerged that contribute to a deeper understanding of the biological mechanisms of hearing. However, the latest research represents an exciting direction as it fundamentally questions our current knowledge regarding sound transformation occurring in the ear. Understanding the process of hearing is not only important from a scientific perspective but also has practical significance. The new discoveries examining the role of hair cells and ion channels in the inner ear shed new light on the possibilities for treating hearing loss. The precise localization of ion channels, which previously…
