Morphological characterization of the melanin-concentrating hormone in the brain of humans, rodents, and birds
The regulation of food intake and energy balance is an extremely complex process involving numerous physiological and neurobiological mechanisms. The central nervous system, particularly the hypothalamus, plays a key role in integrating these mechanisms. Signals from various areas of the brain, which originate from peripheral systems such as the digestive system and adipose tissue, arrive in the form of humoral and neural impulses. In response to these factors, the hypothalamus decides whether an increase or decrease in food intake is necessary. Factors Influencing Food Intake One of the factors influencing food intake is our mood, which is also affected by the limbic system and other higher brain structures. This complex…

The effect of soy on the thyroid
The relationship between soy consumption and thyroid function has long intrigued the scientific community. The debate has intensified, especially since soy-based foods have become increasingly popular, particularly with the rise of vegetarian and vegan diets. People are increasingly seeking plant-based alternatives, and soy plays a prominent role in this shift. Soy is not only an alternative source of protein for vegetarians and vegans, but dietary supplements aimed at alleviating menopausal symptoms are also gaining popularity. However, understanding the effects of soy on thyroid function is not straightforward, as research often reaches differing conclusions. To understand thyroid function, it is important to consider the hormonal balance, with TSH (thyroid-stimulating hormone) being…

A genetic mutation is behind severe hypoglycemia
The sudden drop in blood sugar levels, known as hypoglycemia, is a serious health issue that affects many people’s lives. Various factors, including genetic ones, can underlie this condition. Regulating blood sugar levels is vital for the healthy functioning of the body, as glucose is one of the main energy sources. When blood sugar levels drop too low, it can cause many uncomfortable and life-threatening symptoms. Hypoglycemia is common among diabetics, especially those who manage their condition with insulin. However, hypoglycemia can also be caused by certain genetic disorders that affect the functioning of hormones and genes responsible for blood sugar regulation. Recent research indicates that mutations in the AKT2…

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…

PCOS: The Most Common Infertility Factor
A hormonal imbalance disorders among women deserve particular attention, as they can lead to numerous health issues. One of the most common of these is polycystic ovary syndrome, which primarily affects young and middle-aged women. PCOS, as it is commonly abbreviated, not only affects the ovaries but also complexly influences hormonal and metabolic processes. The background of the disease often involves hereditary factors, and modern lifestyle choices, such as stress, lack of physical activity, and poor nutrition, can further complicate treatment. PCOS is also closely related to insulin resistance, which increases the risk of diabetes; therefore, it is important for women to be aware of the signs and symptoms of…

Analysis of thyroperoxidase autoantibodies (anti-TPO)
A role of thyroid hormones in the body’s functioning is of outstanding significance. These hormones affect growth and development, regulate metabolism, influence heart function, and have a significant impact on the development and functioning of the nervous system. Additionally, thyroid hormones also affect muscle structure, glucose metabolism, and calcium metabolism. Examining Thyroid Function When examining thyroid function, several factors must be considered. It is important to measure the levels of hormones produced by the thyroid, such as fT4 and fT3, as well as the level of TSH, which regulates the thyroid. Additionally, antibodies produced against certain parts of the thyroid, such as anti-TPO, TRAK, and Tg antibodies, are also significant,…

Goals of Insulin Therapy
Az inzulin plays a significant role in human metabolism, which is crucial for the process of glucose uptake and storage. When the body cannot produce enough insulin, or its effectiveness decreases, the cells are unable to properly absorb glucose, leading to high blood sugar levels. This phenomenon can result in serious health problems, including diabetes, which is one of the greatest challenges in modern society. The Function of Insulin The function of insulin is a complex process centered around the hormone produced by the beta cells found in the pancreas. Under the influence of insulin, cells, particularly in the liver, muscles, and adipose tissue, are able to take up glucose,…

Insulin Injections – Dosage and Method of Application
Diabetes, also known as diabetes mellitus, is a complex metabolic disorder that can present in various forms. One of the central issues of this disease is the anomalies related to the insulin hormone, which often necessitate insulin injections for patients. Insulin is the hormone responsible for regulating blood sugar levels, and its deficiency or ineffectiveness can have serious consequences. Types of Diabetes and Insulin Needs Different types of diabetes can cause varying insulin needs. In type 1 diabetes, the pancreas does not produce enough insulin, requiring patients to obtain insulin from external sources. In contrast, type 2 diabetes can initially be managed with various medications that enhance the pancreas’s insulin…
