The breech position may be genetically determined
The process of childbirth is extremely complex, and several factors influence the position in which the fetus enters the world. The most common birthing position is head-first delivery; however, it is possible for the fetus to enter the birth canal in a breech or footling position. This situation accounts for a relatively small percentage of births, less than 5 percent, but it can pose significant risks, such as stillbirth or other health problems. To understand the causes of breech births, the scientific community is continuously researching the phenomenon. According to the latest findings, genetic background may also play a role in the occurrence of breech births. This discovery could provide…

Dandy-Walker syndrome
The Dandy-Walker syndrome (DWS) is a rare, congenital brain developmental disorder that affects the central nervous system and typically impacts the back part of the brain, particularly the cerebellum and the fourth ventricle. This disorder is associated with the disruption of cerebrospinal fluid drainage, which causes severe central nervous system problems. The manifestation of the syndrome can be linked to various factors, and understanding the disease as well as knowledge of related information is extremely important for proper diagnosis and treatment. Dandy-Walker syndrome is a complex condition that can cause problems in various areas, including motor functions, behavior, and cognitive abilities. In addition to exploring the causes of the disorder,…

Swedish researchers studied the genetic background of prostate cancer
The prostate cancer is receiving increasing attention from the scientific community, especially regarding the role of heredity. The incidence and risk factors of the disease represent an important research area for scientists. To expand knowledge about prostate cancer, experts are examining various populations to better understand how genetic factors influence the development of the disease. Research has shown that the probability of developing prostate cancer significantly increases if there is a history of the disease in the family. For men, knowing whether a sibling or parent has had the disease not only serves to assess individual risks but also highlights the importance of prevention and screening. With this information, men…

Australia launches the world’s first preventive DNA testing
A modern orvostudomány folyamatosan fejlődik, és a genetikai vizsgálatok terén elért eredmények különösen figyelemre méltók. A genetikai szűrések lehetőségei egyre szélesebb körben érhetőek el, ami különösen fontos a fiatalok számára, akik számára a megelőzés kulcsfontosságú lehet. A genetikai tesztelés révén korai információkat kaphatunk arról, hogy milyen betegségekre lehetünk hajlamosak, így a megfelelő intézkedéseket időben megtehetjük. Genetikai szűrések a fiatalok számára A Monash Egyetem által vezetett projekt célja, hogy a 18 és 40 év közötti fiatalok számára lehetőséget adjon arra, hogy ingyenes nyálteszteken keresztül tájékozódjanak a rákos megbetegedések és szívbetegségek kockázatáról. A szűrés során a résztvevők genetikai profiljának elemzése történik, amely során a kutatók olyan géneket vizsgálnak, mint a BRCA1 és…

The abnormal factors of early graying
Az ősz haj megjelenése gyakran a természetes öregedés egyik jeleként van jelen a köztudatban, mivel a legtöbb ember 50 éves korában tapasztalja ezt a változást. Az őszülés hátterében a haj színét meghatározó melanin pigment csökkenése áll. Az öregedés folyamatával a melanintermelés folyamata fokozatosan lelassul, ami végül a hajszálak elvesztését eredményezi a természetes pigmentációban. Azonban nem csupán az idő múlása idézheti elő az ősz hajat; bizonyos betegségek és gyógyszerek is hozzájárulhatnak a korai őszüléshez. A haj gyökere és a melanin A haj gyökere a fejbőrben található, és a hajhagymának nevezett kiszélesedett részénél található a melanociták, amelyek felelősek a melanin termeléséért. A hajszálak színét ez a pigment határozza meg, így a haj…

Gene responsible for the formation of cleft lip discovered
A genetic research continuously uncovers new information about human development and the background of various disorders. One notable discovery is cleft lip, a condition that causes deformity of the upper lip in infants. Cleft lip not only presents aesthetic problems but also functional difficulties, such as making breastfeeding challenging. Uncovering the genetic background of such conditions is crucial for prevention and treatment. The causes of cleft lip can be diverse, and researchers have been working for years to understand the genetic factors involved. Recent studies show that certain gene alterations can significantly impact the appearance of cleft lip. For scientists, this topic is not just a scientific curiosity but also…

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…

Physical Activity, Performance, and Heredity
The world of sports performance showcases numerous outstanding achievements that often surprise us. Behind every success lies hard work, but the question arises: is diligent training enough, or do genetic predispositions also play a decisive role in exceptional performances? The impact of genetics on sports performance is becoming increasingly recognized. Every individual possesses different attributes and backgrounds that influence the sports in which they can achieve success. For example, Africa’s famous runners owe their achievements not only to rigorous training but also to their genetic advantages shaped by centuries of experience and lifestyle. Regular exercise, particularly running, significantly affects their genetic makeup, enabling them to deliver outstanding performances. Thus, genetic…

The disease of thalassemia
The hemoglobin, a protein found in red blood cells, plays a crucial role in the body’s oxygen supply. The level and function of hemoglobin are key to ensuring that tissues receive adequate oxygen, as any disruption in hemoglobin formation can lead to anemia and hypoxic conditions. The macromolecules that make up hemoglobin have a complex structure, which includes a heme ring containing iron and four globin chains, two of which are alpha and two are non-alpha isoforms. Among the disorders of hemoglobin formation, thalassemia plays a prominent role, a group of hereditary diseases that affect the globin chain of hemoglobin. This disease complicates the normal production of hemoglobin, leading to…

Stem cell changes responsible for baldness?
A hair loss, especially baldness, is a problem that affects many people and can arise from various causes. Losing hair poses challenges not only from an aesthetic perspective but also has a serious impact on mental well-being. People often seek solutions to stop or reverse this process. Baldness can manifest in different forms, with the most common type being androgenetic alopecia, which affects both men and women. The Mechanism of Hair Loss The mechanism of hair loss is generally complex, and for a long time, it was explained primarily as a consequence of the destruction of hair follicles. However, recent research suggests that the problem is much more complicated than…
