What is brightfield microscopy?

Brightfield microscopy is a traditional optical microscopy technique in which light is transmitted through a biological or material sample, illuminating it and allowing for the observation of details. The sample is placed between two lenses - the objective and the ocular - and light passes through the sample, creating a visible image. This method is most commonly used in biology and medical laboratories to observe cells, tissues, and other thinly colored or uncolored specimens. Brightfield microscopy allows for the visualization of samples in their natural colors or using special stains.

Why is microscopy relevant for the detection of oxidative stress?

Oxidative status represents the balance between free radicals and antioxidants in our bodies. Imbalance in favor of free radicals leads to oxidative stress, which can cause damage to cells and tissues and contribute to various diseases, including inflammatory, infectious, autoimmune, cardiovascular, pulmonary, and anemic conditions.

By testing oxidative stress, we can measure the degree of blood oxidation, ranging from mild forms, where oxidative processes cover 10% of the total blood, to severe forms of oxidation (Stage 4), where the fibrin network is completely damaged, and over 30% of the total blood in the coagulated drops collected for testing is lost. This can indicate the presence of advanced degenerative diseases.

The coagulated blood drop is considered a holographic representation of the human body, similar to iridology. The various circles in the coagulated drop represent different parts of the human body, so changes observed in certain areas of the coagulated drop can provide information about the state of our health. It can also determine whether identified conditions are in an acute or chronic form.

By testing coagulated blood drops, we can determine the presence of free radicals, monitor inflammatory processes and oxidative stress, identify the presence of heavy metals, parasites, and viral forms, mineral deficiencies, hormonal imbalances, upper or lower abdominal inflammation, allergies, adrenal gland impairment, lymphatic congestion, cardiovascular conditions, the presence of advanced stages of degeneration (precancerous forms, autoimmune diseases), deficiencies in metabolism, and the absorption of antioxidants.

Oxidative Stress

Oxidative stress is an imbalance between the production of free radicals and the body's ability to neutralize or repair the effects of these free radicals. Free radicals are molecules or atoms that contain unpaired electrons, making them highly chemically reactive. These free radicals can react with other molecules in the body, including proteins, lipids, and DNA.

Free radicals can be generated in the body naturally as part of normal metabolic processes, but they can also be produced in excess in response to external factors such as radiation, pollution, smoking, or diet. When the production of free radicals exceeds the body's capacity to neutralize or repair the damage they cause, oxidative stress occurs.

Oxidative stress can have harmful effects on cells and tissues in the body. It can cause damage to DNA, proteins, and lipids, which can contribute to the development of conditions such as cancer, cardiovascular diseases, type 2 diabetes, neurodegenerative diseases, and more. Additionally, oxidative stress is involved in the aging process.

What is oxidative stress?

Oxidative stress is an imbalance in the body between the production of free radicals (reactive oxygen species or unstable oxygen-containing molecules) and the body's ability to neutralize or repair the damage caused by these free radicals. Free radicals can be generated in the body naturally, but they can also be formed in excess due to exposure to stressors such as radiation, pollution, toxins, psychological stress, or through normal metabolic processes in the body. These free radicals can affect cells, proteins, DNA, and other cellular components, causing oxidative damage. Oxidative stress is associated with several health conditions, including cardiovascular diseases, premature aging, cancer, and neurodegenerative diseases.

Causes and Symptoms of Oxidative Stress

The causes of oxidative stress can include:

  1. Poor Diet: Excessive consumption of processed foods high in unhealthy fats and sugars can increase the production of free radicals in the body.

  2. Smoking: Tobacco contains chemicals that can produce free radicals and reduce the body's ability to neutralize them.

  3. Excessive Alcohol Consumption: Alcohol can disrupt the body's antioxidant balance, increasing oxidative stress.

  4. Environmental Pollution: Exposure to air pollutants or toxic chemicals can contribute to the production of free radicals.

  5. Radiation and Sun Exposure: Ionizing radiation and excessive UV radiation from the sun can induce oxidative stress in the skin and skin cells.

The symptoms of oxidative stress can vary and may include:

  1. Chronic fatigue
  2. Muscle weakness
  3. Joint pain
  4. Increased risk of cardiovascular diseases
  5. Premature aging of the skin
  6. Increased vulnerability to infectious diseases
  7. Increased risk of neurodegenerative diseases such as Alzheimer's and Parkinson's.

Long-Term Consequences of Oxidative Stress in the Body

Persistent oxidative stress can have long-term negative consequences on health. These consequences include:

  1. DNA Damage: Free radicals can damage DNA and contribute to the development of genetic mutations, increasing the risk of cancer.

  2. Premature Aging: Oxidative stress can accelerate the aging process of the skin and lead to the development of wrinkles and other signs of premature aging.

  3. Chronic Diseases: Chronic oxidative stress is associated with the development of chronic diseases, such as cardiovascular diseases, type 2 diabetes, and neurodegenerative diseases.

  4. Chronic Inflammation: Oxidative stress can trigger a chronic inflammatory response in the body, which can contribute to various diseases and conditions.

  5. Tissue Damage: Free radicals can cause damage to tissues and organs, affecting their normal function.

Free Radicals and Their Impact on the Body

Free radicals are molecules with an odd number of electrons that can be highly reactive and cause cellular damage. In the body, these free radicals can be produced as part of normal metabolic processes, but they can also be generated as a result of exposure to stressors. Free radicals include species such as superoxide, peroxides, and the hydroxyl radical.

The body has an antioxidant system to neutralize and counteract the effects of free radicals. This system involves enzymes such as superoxide dismutase, catalase, and glutathione peroxidase, as well as antioxidants such as vitamin C, vitamin E, and glutathione.

In moderate amounts, free radicals have beneficial roles in the body, such as destroying bacteria and viruses. However, excessive levels of free radicals and associated oxidative stress can cause cellular damage and contribute to various health problems.

To reduce oxidative stress and minimize the impact of free radicals, a healthy diet, avoidance of smoking and excessive alcohol consumption, and protection of the skin from excessive sun exposure can play an essential role. Additionally, antioxidant supplements may be useful but should be taken with caution and under medical supervision.

Detecting Free Radicals Using Brightfield Microscopy

Brightfield microscopy (LM), also known as "brightfield microscopy" in English, is an imaging technique that uses transmitted light to observe biological or material samples at a microscopic level. However, detecting free radicals using brightfield microscopy can be challenging because free radicals are extremely small and reactive molecules, invisible directly under a conventional microscope. Nevertheless, there can be indirect methods to assess the presence or impact of free radicals in biological samples. These methods may involve the use of chemicals sensitive to free radicals, such as dyes or oxidation indicators that can change absorption or fluorescence properties in the presence of these radicals.

What Are Free Radicals?

Free radicals are molecular species that contain one or more oxygen atoms and have an odd number of electrons in an outer orbital. This configuration makes free radicals highly reactive as they attempt to complete their number of electrons, which leads them to interact with other molecules to gain or lose electrons. Free radicals can be formed in the body as part of normal metabolic processes, but they can also be generated in excess due to exposure to stressors, such as radiation, pollution, or toxic chemicals.

Free radicals can have a negative impact on the body by causing cellular damage. This damage can contribute to the onset of diseases, premature aging, and other adverse health effects.

Reactive Oxygen Species: What Are They and Why Are They Important?

Reactive oxygen species (ROS) are a category of oxygen-containing free radicals that are highly reactive. They include superoxide (O2•-), hydrogen peroxide (H2O2), the hydroxyl radical (•OH), and others. ROS are normally produced in the body during cellular processes, such as cellular respiration and the immune system. However, excessive levels of ROS can lead to oxidative stress and cause cellular damage.

ROS can be important for the body as they are involved in cellular signaling processes, such as the immune response to infections. However, elevated levels of ROS can lead to oxidative damage and may be associated with diseases, including cardiovascular diseases, neurodegenerative diseases, and cancer.

Neutralizing Free Radicals: Antioxidants and Defense Mechanisms

To neutralize the harmful effects of free radicals and reactive oxygen species, the body has antioxidant defense mechanisms. These mechanisms include:

Antioxidant Enzymes: Enzymes like superoxide dismutase, catalase, and glutathione peroxidase help neutralize free radicals and ROS.

Non-enzymatic Antioxidants: Substances such as vitamin C, vitamin E, glutathione, and beta-carotene act as antioxidants, protecting cells from oxidative damage.

DNA Repair: The body has DNA repair mechanisms to correct damage caused by free radicals.

Other Cellular Mechanisms: Cells have mechanisms to neutralize ROS and maintain oxidative balance within cells.

A proper intake of antioxidants from the diet and a healthy lifestyle, including avoiding smoking and excessive alcohol consumption, can contribute to reducing oxidative stress and maintaining overall health.

Oncology and Oxidative Stress

Oncology is the branch of medicine that deals with the study and treatment of cancer. Oxidative stress is an important research area in oncology because there is a close connection between oxidative stress and the development of cancer. Studies have shown that oxidative stress can play a significant role in the initiation and progression of cancer.

The Link Between Oxidative Stress and Carcinogenesis

Carcinogenesis is the process by which healthy cells undergo genetic and epigenetic changes that make them malignant, leading to the development of cancer. Oxidative stress can influence carcinogenesis in several ways:

  1. DNA Damage: Free radicals and reactive oxygen species can cause damage to DNA. This damage can lead to genetic mutations and contribute to the formation of cancer cells. DNA damage can affect genes that regulate cell growth and division, as well as genes involved in DNA repair.

  2. Promotion of Inflammation: Oxidative stress can trigger a chronic inflammatory response in tissues, creating an environment favorable to cancer development. Chronic inflammation can stimulate cell division and angiogenesis (the formation of new blood vessels), which are important in tumor growth.

  3. Development of Angiogenesis: ROS can stimulate the production of growth factors and cytokines involved in the formation of new blood vessels (angiogenesis), which is essential for supplying tumors with blood and nutrients.

  4. Cancer Defense: On the other hand, oxidative stress can also play a role in cancer defense. ROS can have a toxic effect on cancer cells, slowing down tumor growth. However, these effects can be overcome by the ability of cancer cells to develop mechanisms of resistance to oxidative stress.

In conclusion, the link between oxidative stress and carcinogenesis is complex. Oxidative stress can contribute to the initiation and progression of cancer through DNA damage, inflammation promotion, and angiogenesis development. However, it can also play a role in cancer defense.

In general, brightfield microscopy is an essential tool in cancer management, providing high-quality care for oncology patients.

Preventive Medicine: The Importance of Early Detection of Oxidative Stress

Preventive medicine focuses on disease prevention and maintaining an individual's overall health. Early detection of oxidative stress can play a crucial role in preventive medicine because it offers the opportunity to intervene before oxidative damage leads to the development of diseases. Oxidative stress is associated with various conditions, including cardiovascular diseases, cancer, type 2 diabetes, and neurodegenerative diseases. By identifying and managing oxidative stress in its early stages, the risk of developing these diseases can be reduced.

The Role of Brightfield Microscopy in Preventive Medicine

Brightfield microscopy can have a significant role in preventive medicine by enabling the observation and analysis of tissues and cells at the microscopic level. This technique can help detect early signs of oxidative stress and other abnormal cellular changes, which may indicate the presence of a condition. For example, cellular structures or morphological changes suggesting cellular damage caused by oxidative stress can be observed. Thus, brightfield microscopy can be useful in monitoring the health of patients and early intervention to prevent the onset of diseases.

Oxidative Stress and Immune Competence

Oxidative stress can influence the functioning of the immune system. Immune competence refers to the immune system's ability to respond effectively to infections and other aggressors. Oxidative stress can compromise the immune system by causing damage to immune cells and suppressing their immune response. This can lead to increased susceptibility to infections and difficulty in the body's ability to combat pathogens.

The Impact of Oxidative Stress on the Immune System

Oxidative stress can affect the immune system in several ways:

  1. Cellular Damage: Free radicals and reactive oxygen species can cause damage to immune cells such as lymphocytes and macrophages. This can affect the ability of these cells to function properly in fighting infections.

  2. Suppression of the Immune Response: Oxidative stress can suppress the immune response by reducing the production of cytokines and growth factors necessary for the activation and proliferation of immune cells.

  3. Chronic Oxidative Stress: Chronic oxidative stress, such as that induced by pollution or smoking, can lead to chronic inflammation, which can contribute to immune system dysfunction.

The Benefits of Early Detection for Immune Maintenance

Early detection of oxidative stress and related changes in the immune system can be crucial for maintaining a healthy immune system. Early intervention and management of oxidative stress can help maintain optimal immune system function and reduce the risk of infections and immune-related conditions. Thus, preventive medicine can play an essential role in preserving immune health and promoting disease resistance.
