The Role of Biomaterials in Regenerative Medicine

Biomaterials used in regenerative medicine are engineered to interact with biological systems to aid in the healing process. They can be derived from natural sources, such as collagen and hyaluronic acid, or synthesized, such as polylactic acid (PLA) and polyethylene glycol (PEG). “The primary function of biomaterials in this field is to provide a supportive framework that mimics the extracellular matrix,” explains Dr. Emily White, a specialist in biomaterials. This framework is crucial for promoting cell adhesion, growth, and differentiation, which are essential for tissue regeneration.

Innovations in Biomaterial Development

Smart Biomaterials

One of the most exciting developments in biomaterials is the advent of smart materials that can respond to environmental changes. “Smart biomaterials can release therapeutic agents, change shape, or adjust their properties in response to stimuli like temperature, pH, or light,” says Dr. Mark Johnson, an innovator in biomaterial technology. This adaptability makes them ideal for applications such as controlled drug delivery and responsive tissue scaffolds.

Biodegradable and Bioabsorbable Materials

The use of biodegradable and bioabsorbable materials is another significant advancement. These materials are designed to degrade naturally in the body after serving their purpose, reducing the need for surgical removal. “Biodegradable biomaterials are particularly useful in applications like sutures, stents, and temporary scaffolds for tissue engineering,” notes Dr. Sarah Lee, a researcher in medical polymers.

Nanomaterials and Nanocomposites

Nanotechnology is playing a transformative role in the development of biomaterials. Nanomaterials and nanocomposites can be engineered at the molecular level to enhance their mechanical, chemical, and biological properties. “The use of nanoparticles in biomaterials allows for precise control over drug delivery and the creation of scaffolds with enhanced mechanical strength and bioactivity,” explains Dr. Michael Green, a nanotechnology expert.

Applications in Tissue Engineering and Regenerative Medicine

Biomaterials are being used in various regenerative medicine applications, from skin regeneration and bone repair to the development of artificial organs. “The versatility of biomaterials makes them suitable for a wide range of medical applications, including the regeneration of complex tissues like cartilage and nerves,” says Dr. Laura Smith, a tissue engineering specialist.

For instance, in bone regeneration, biomaterials such as calcium phosphate and hydroxyapatite are used to create scaffolds that mimic the mineral composition of bone. These scaffolds support the growth of new bone cells and facilitate the integration of the new tissue with the existing bone. “Biomaterials in bone regeneration not only provide structural support but also promote osteogenesis and vascularization,” notes Dr. David Chan, an orthopedic researcher.

In the field of skin regeneration, biomaterials are used to develop advanced wound dressings and skin grafts that accelerate healing and reduce scarring. “Hydrogel-based biomaterials are particularly effective in maintaining a moist wound environment and delivering bioactive molecules that promote tissue repair,” highlights Dr. Maria Lopez, a dermatology expert.

Challenges and Future Directions

Despite the significant progress, challenges remain in the field of biomaterials. One major challenge is ensuring the biocompatibility and safety of new materials. “It is crucial to thoroughly evaluate the long-term effects of biomaterials in the body to avoid adverse reactions,” cautions Dr. Karen Johnson, a clinical researcher.

Another challenge is the scalability of biomaterial production. “Developing cost-effective and scalable manufacturing processes is essential for making advanced biomaterials accessible to a wider range of patients,” says Dr. Alex Lee, an industrial engineer.

Looking ahead, the future of biomaterials in regenerative medicine is promising, with ongoing research focused on developing more sophisticated and multifunctional materials. “The integration of biomaterials with emerging technologies like 3D printing and bioprinting is set to revolutionize the field, enabling the creation of personalized and complex tissue structures,” predicts Dr. Emily Wang, a futurist in medical technology.
Biomaterials are at the forefront of regenerative medicine, driving innovation and expanding the possibilities for medical treatments. As research continues to advance, these materials will play an increasingly crucial role in developing therapies that not only repair and replace damaged tissues but also restore their full functionality. The future of healthcare lies in harnessing the potential of biomaterials to transform patient care and improve quality of life.

The Foundation of 3D Bioprinting: Biomaterials

Biomaterials are substances engineered to interact with biological systems for therapeutic or diagnostic purposes. In 3D bioprinting, these materials are used to create scaffolds that provide a supportive structure for cells to grow and develop into tissues. “Biomaterials are the cornerstone of tissue engineering; they provide the physical and biochemical environment needed for cells to function and thrive,” says Dr. Emily Wang, a leading researcher in biomaterials science.

These materials must possess certain properties to be effective in bioprinting. They need to be biocompatible, ensuring they do not provoke an immune response, and bioactive, meaning they can support cellular activities such as adhesion, proliferation, and differentiation. “The choice of biomaterial can significantly impact the success of the bioprinting process and the functionality of the engineered tissue,” notes Mark Thompson from palms bet bg.

Types of Biomaterials Used in 3D Bioprinting

Several types of biomaterials are used in 3D bioprinting, each offering unique advantages:

Hydrogels: Hydrogels are highly absorbent polymers that can retain a large amount of water, making them similar to natural tissue. “Hydrogels are popular in bioprinting because of their tunable properties and ability to mimic the extracellular matrix,” explains Dr. Sarah Lee, a materials scientist. They can be engineered to provide mechanical support and deliver growth factors, which are essential for tissue development.

Biopolymers: Biopolymers such as collagen, fibrin, and gelatin are derived from natural sources and are known for their biocompatibility and biodegradability. “Biopolymers are ideal for creating scaffolds that degrade over time, allowing the natural tissue to replace the engineered structure,” says Dr. Michael Green, a biopolymers specialist. This property is particularly important in applications like wound healing and organ regeneration.

Synthetic Polymers: Synthetic polymers like polylactic acid (PLA) and polyglycolic acid (PGA) are also used due to their customizable properties. “Synthetic polymers can be precisely engineered to achieve specific mechanical and chemical characteristics, making them versatile for various bioprinting applications,” highlights Dr. Laura Smith, a chemical engineer.

Innovations and Challenges in Biomaterial Development

Recent innovations in biomaterial development have focused on enhancing the functionality and versatility of these materials. For example, researchers are exploring the use of smart biomaterials that can respond to environmental stimuli, such as changes in temperature or pH, to release drugs or growth factors. “Smart biomaterials represent a new frontier in tissue engineering, offering dynamic control over the tissue microenvironment,” states Dr. David Chan, an innovator in biomaterials research.

However, challenges remain in the field, particularly in scaling up the production of biomaterials and ensuring consistency in quality. “One of the biggest hurdles is translating laboratory-scale biomaterials to clinical applications, where large quantities and rigorous safety standards are required,” notes Dr. Jessica Brown, a regulatory scientist.

Additionally, the integration of biomaterials with living cells poses significant technical challenges. Maintaining cell viability and function during the bioprinting process is critical. “Ensuring that cells remain viable and retain their functional properties post-printing is essential for the success of tissue engineering,” emphasizes Dr. Karen Johnson, a cellular biologist.

Future Directions and Applications

The future of biomaterials in 3D bioprinting holds exciting potential for medical and therapeutic applications. One of the most promising areas is organ printing, where fully functional organs could be printed and transplanted, addressing the shortage of donor organs. “The ultimate goal is to create patient-specific tissues and organs that can replace damaged ones, offering a personalized approach to medicine,” says Dr. Alex Lee, a pioneer in organ bioprinting.

Another emerging application is the use of bioprinted tissues for drug testing and disease modeling, providing more accurate and ethical alternatives to animal testing. “Bioprinted tissues can mimic the complexity of human organs, offering a better platform for testing drug efficacy and toxicity,” explains pharmaceutical researcher Dr. Maria Lopez.

Biomaterials play a pivotal role in the advancement of 3D bioprinting and tissue engineering. Their development and refinement are crucial for creating functional and clinically viable tissues. As research continues to push the boundaries of what is possible, biomaterials will undoubtedly remain at the forefront of innovation, paving the way for breakthroughs in regenerative medicine and beyond. As Dr. Emily Wang aptly puts it, “The intersection of biology, engineering, and materials science in bioprinting offers unparalleled opportunities to transform healthcare and improve lives.”

Diagnostic advancements

One of the most critical areas where technology has made a profound impact is in diagnostics. The advent of sophisticated imaging techniques, such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scans, and Positron Emission Tomography (PET) scans, has revolutionized how diseases are detected and monitored. These imaging technologies provide detailed insights into the human body, allowing for early detection of conditions that might not be visible through traditional diagnostic methods.

In addition to imaging, molecular diagnostics have become a game-changer. Techniques like Polymerase Chain Reaction (PCR) and Next-Generation Sequencing (NGS) enable the identification of genetic markers and mutations associated with various diseases, including cancer. This level of precision allows for personalized treatment plans tailored to the genetic makeup of individual patients, improving the effectiveness of therapies and minimizing side effects.

Moreover, artificial intelligence (AI) is increasingly being integrated into diagnostic processes. AI algorithms can analyze vast amounts of medical data, identifying patterns and anomalies that might be missed by human eyes. For instance, AI-powered tools are being used to read radiology images, providing second opinions and enhancing the accuracy of diagnoses. This not only speeds up the diagnostic process but also ensures that patients receive timely and accurate information about their health conditions.

Treatment innovations

Technological advancements are also driving significant improvements in treatment methods. One of the most notable developments is the use of minimally invasive surgical techniques. Procedures such as laparoscopic surgery and robotic-assisted surgery have reduced the need for large incisions, leading to shorter recovery times, less pain, and lower risk of complications for patients.

Robotic surgery, in particular, has gained popularity due to its precision and control. Surgeons use robotic systems to perform complex procedures with greater accuracy than traditional methods. These systems offer enhanced dexterity and visualization, allowing surgeons to operate in tight spaces within the body. As a result, patients experience quicker recovery and better outcomes.

Another area of innovation is in the field of regenerative medicine. Stem cell therapy and tissue engineering are paving the way for treatments that can repair or replace damaged tissues and organs. These technologies hold promise for treating a wide range of conditions, from spinal cord injuries to heart disease. By harnessing the body’s natural healing processes, regenerative medicine offers the potential to cure previously untreatable ailments.

Additionally, targeted therapies are revolutionizing the treatment of diseases like cancer. These therapies focus on specific molecules or pathways involved in the growth and spread of cancer cells, minimizing damage to healthy cells. Immunotherapy, a type of targeted therapy, has shown remarkable success in treating certain cancers by boosting the body’s immune system to recognize and attack cancer cells.

The integration of digital health

The integration of digital health technologies is another area where medicine is undergoing a transformation.

Is Love Biological or Not?

From a medical perspective, falling in love is based on a whole diversity of biological processes happening in the brain and body. One of the main biological factors that determine whether we will fall in love or not is the release of certain chemicals in the brain, including dopamine, oxytocin, and vasopressin. 

• Dopamine. Dopamine is a hormone that is related to getting pleasure and reward. Our body releases dopamine every time we have some positive feelings, such as happiness and satisfaction. 
• Oxytocin and vasopressin. These two hormones are involved in social bonding and creating the feeling of attachment.

How do these hormones work?

When we fall for someone, our brain releases a great amount of dopamine, oxytocin, and vasopressin. Altogether, these hormones create feelings of euphoria, bonding, and attachment, as well as influence our heart rate, breathing, and blood pressure.

How do we get attracted to someone?

Overall, attraction is a complex notion that is influenced by many factors, such as physical appearance, personality, similarity, proximity, familiarity, and social influence. 

• Physical appearance. There is hardly anyone who would dispute the fact that we pay attention to the appearance of our potential partners. The body shape, facial features, smell, overall attractiveness, and even the clothes and perfume influence our first impression of the person.
• Personality traits. Though we are all looking for particular traits, some things trigger all of us, such as confidence, humor, kindness, and intelligence.
• Similarity. We often choose partners who have similar interests, values, and backgrounds to ours.
• Proximity. It is scientifically proven that we choose partners based on geographical vicinity. We are more likely to fall for someone with whom we spend time or share some territory.
• Familiarity. We are also more likely to fall in love with someone who we already know or someone who knows the people we know well. This factor works a bit like recommendations at work. We are also influenced by the opinions and actions of our peers, so we can get attracted to someone popular or well-liked in our company or community. 

Though many people have their explanations of attractiveness, this complex notion can not always be explained with logic and words. This process often has roots in our subconscious that’s why we can get attracted to someone for reasons we don’t fully understand or can’t explain.

What is the role of sent in love?

Unlike other animals, humans rely less on their sense of smell. However, recent research shows that our noses can identify particular chemical signals in a potential partner. These slight signals combined with other information help us estimate the probability of love interest. 

In addition, the reward system starts to play. If you have a positive experience with someone whose smell you like, your body starts to seek a similar good experience and focuses on finding this smell later as well. 

And what about taste?

All people have particular flavors and breaths. Some people try to hide it using sweets and mints, and this technique even has scientific meaning. Human beings are naturally more attracted to sweet and salty things. Not in vain, sweet things are often associated with romance and dating. Some studies proved that consuming something sweet, say a drink or cake, on a date or while checking the dating app, increases our desire for a potential partner. The brain’s pleasure center is encouraged with a quick dopamine shot, and hence we want to repeat the experience, be it a date or chat. 

How does touch trigger love?

Touching can create a strong feeling of pleasure as it provokes a release of dopamine and oxytocin. Such small things as holding hands and kissing gently can bit by bit build a feeling of love inside. However, if a person feels unsafe, the same touch can vice versa destroy even the small feeling of newborn love. So be careful with respecting the boundaries of your partner. 

Do you believe that love is triggered by body signals or only the matter of heart and soul?

The post The Biology of Love: How Does Our Body Fall in Love appeared first on Medical Structure.

Neuroscience is a popular and rapidly emerging scientific branch, which deals with the structure or function of the nervous system and brain. Numerous studies in this field shed light on how we feel, think, remember, and even on how we program our lives. Some studies explain even such magical and sophisticated things as love and commitment. Below we want to share the key findings in this domain. 

Love activates the reward system

The reward system is a part of the brain that releases dopamine. This specific neurotransmitter is associated with pleasure and reward. Every time we experience a pleasurable event the reward system is activated. There have been studies that showed how the brains of lovers work when they see their partners. Indeed, the dopamine release made people feel happiness and even euphoria. Brain scans showed that love activates the same areas in our brain as food and strong drugs, like cocaine and opioids, do.

Unfortunately, the reward system also plays against us when we decide to break up. After the end of a relationship, the brain which was already used to rewarding chemicals feels a significant drop in them. This leads to feelings of sadness, anxiety, and withdrawal. There is no partner to stimulate the reward system anymore and we feel emotional pain and longing.

Love relies on the attachment system

The attachment system is part of the brain that is in charge of creating powerful emotional connections between individuals. Thanks to this system, we are able to feel closeness, intimacy, safety, and comfort with other people. 

The attachment system consists of several brain regions, including the prefrontal cortex, the amygdala, and the anterior cingulate cortex. Together they regulate how we react emotionally to other people’s words and feelings. The attachment system defines how we build all types of close relationships, from the bonds with our parents and friends to connections with love partners. As for romantic relationships, the attachment system allows us to build long-term relationships. The levels of satisfaction, conflicts, and stress are way better in couples whose attachment systems work well. 

Love changes the brain structure

Research has shown that long-term, committed relationships bring changes to our brain structure. A long-term relationship (about 25 years) leads to the appearance of more gray matter in the anterior cingulate cortex, insula, and dorsal striatum regions of the brain (compared to single people). The regions affected are responsible for empathy, emotion regulation, and reward processing. In addition, the parts involved in decision-making, empathy, social behavior, and social cognition are also growing in long-term relationships. This means that people get more used to understanding social cues if they manage to maintain a durable relationship.

Love reduces stress and improves health

Some research has shown that people engaged in a happy marriage in general have lower levels of cortisol than singles. Even such simple gestures as holding hands with your lover can reduce stress levels. As a result, you can benefit from stronger immunity and better cognition and reduce the risks of diabetes and obesity.  

Love relies on mirror neurons

Mirror neurons are brain cells that fire both when we perform an action and observe someone doing it. Mirror neurons have a significant role in empathy, social learning, and different social behaviors. These cells are also responsible for the ability to feel connected to another person. Just observing our love partner when he or she experiences some emotion makes us feel the same level of joy, sadness, or anger. This way, we can connect on a deeper level with time. These cells also let us mirror our partner, showing the same behaviors and gestures and this way building trust. While these areas still require a lot of research, there is already enough evidence that mirror brain cells play a crucial role in the ability to create and keep close emotional bonds with other people.

While neuroscience has recently made a lot of advancements in understanding love, there are still many unknown areas to explore. How do you think love is a purely biological phenomenon or is it destined and more metaphysical?

Nanomedicine could lead to earlier detection and diagnosis of diseases, more effective treatments, and better outcomes for patients. As research in this field continues to advance, it is likely that nanomedicine will become an increasingly important part of modern medicine in the years to come.

What is Nanomedicine and How Can it Help?

Nanomedicine is a rapidly developing field of medicine that uses nanotechnology to diagnose, treat and prevent diseases. This new technology has the potential to revolutionize healthcare, with its ability to target specific cells and molecules in the body, as well as its ability to deliver drugs and other treatments directly to the site of disease.

Nanomedicine is based on the idea of manipulating matter on the nanoscale, which is the scale of atoms and molecules. This enables scientists to design particles and devices that are much smaller than any cell in the human body, but still able to interact with them. These particles can be used to detect and diagnose diseases, deliver drugs or other treatments directly to cells, or even repair damaged tissue.

Nanomedicine has a wide range of potential applications, including diagnosing and treating cancer, cardiovascular disease, neurological disorders, infectious diseases and genetic disorders. For example, nanoparticles can be used to detect cancer cells in the body before they become visible with traditional imaging techniques, allowing for earlier diagnosis and treatment. Nanoparticles can also be used to deliver drugs or other treatments directly to cancer cells, bypassing healthy tissue and reducing side effects.

Nanomedicine also has potential applications in regenerative medicine. Nanoparticles can be used to deliver growth factors or stem cells directly to damaged tissue, which could potentially help to regenerate organs or tissues. This could have implications for treating conditions such as diabetes, heart disease and spinal cord injury.

Nanomedicine is still in its early stages, but it has the potential to revolutionize healthcare and significantly improve patient outcomes. It could help diagnose and treat diseases earlier, as well as improve drug delivery and reduce side effects. It could also be used in regenerative medicine to help repair damaged tissue or organs. With further research and development, nanomedicine could become an integral part of modern healthcare in the future.

Nanomedicine: A Revolution in Healthcare

Nanomedicine is a rapidly growing field of research that has the potential to revolutionize healthcare. This revolutionary technology involves the use of nanoscale particles, such as nanorobots, to detect, diagnose, and treat diseases at a cellular level. Nanomedicine has the potential to revolutionize healthcare by providing more accurate diagnoses, treatments that target specific cells, and improved delivery of drugs.

The use of nanorobots in medicine is still in its infancy, but the potential applications are vast. Nanorobots can be designed to detect specific molecules in the body and provide targeted treatments. For example, nanorobots could be used to detect cancerous cells and deliver targeted therapies that would destroy only those cells without damaging healthy tissue. Nanorobots could also be used to deliver drugs directly to specific sites within the body, improving the effectiveness of treatments.

Nanomedicine could also revolutionize the way we diagnose diseases. By using nanorobots to detect small molecules or cells, doctors could diagnose diseases much earlier than is currently possible. This early detection would enable doctors to begin treatment earlier and could potentially save lives.

In addition to diagnosing and treating diseases, nanomedicine has the potential to improve our overall health by preventing disease before it occurs. Nanorobots could be used to monitor our bodies for signs of disease and alert us before symptoms appear. This could enable us to take preventive measures such as changing our diet or lifestyle habits before the disease progresses.

Nanomedicine is still in its early stages, but the potential applications are incredibly exciting. As research continues, nanomedicine may revolutionize the way we diagnose and treat diseases, ultimately leading to improved health outcomes for all.

Applications of Nanomedicine for Cancer Treatments

Nanomedicine is an emerging field that has the potential to revolutionize cancer treatments. It is a type of medicine that uses nanotechnology to diagnose and treat diseases, including cancer. It has the potential to reduce the side effects of chemotherapy and radiation therapy, as well as improve the effectiveness of cancer treatments.

Nanomedicine is based on the idea of using tiny particles, called nanoparticles, to target and treat cancer cells. The particles can be engineered to carry drugs or other therapeutic agents directly to cancer cells, while avoiding healthy cells. This makes it possible to deliver high doses of drugs and other agents directly to tumors, while minimizing the side effects of traditional treatments.

Nanoparticles can also be used to detect cancer in its early stages. They can be engineered with markers that bind to cancer cells, allowing them to be detected with imaging techniques such as MRI or CT scans. This allows doctors to diagnose cancer earlier, when it is easier to treat.

Nanomedicine also has the potential to improve existing treatments. For example, nanoparticles can be used to deliver chemotherapy drugs directly to tumors, allowing for more targeted treatment and reducing side effects. Nanoparticles can also be used to deliver radiation directly to tumors, allowing for more precise treatment with fewer side effects.

In addition, nanomedicine has the potential to develop new treatments that are not possible with traditional therapies. For example, nanomedicine can be used to develop targeted therapies that act on specific molecules or pathways within cancer cells. This could allow for more personalized treatments that are tailored to each patient’s individual tumor.

Nanomedicine is still in its early stages and much work needs to be done before it can be used in clinical practice. But the potential for nanomedicine to revolutionize cancer treatments is real and exciting. In the future, nanomedicine could provide better outcomes for patients with cancer and improve their quality of life.

Harnessing the Power of Nanotechnology for Health Care

Nanotechnology is a rapidly growing field of science that has the potential to revolutionize the healthcare industry. Nanotechnology, which involves manipulating matter at the atomic or molecular scale, has the potential to create new materials, devices, and systems that are far more efficient and effective than existing technologies. The application of nanotechnology in healthcare has been identified as a key factor in improving patient outcomes and reducing healthcare costs.

The use of nanotechnology in healthcare can be divided into two main categories: medical devices and drug delivery systems. Medical devices are used to diagnose and treat diseases, while drug delivery systems are used to deliver drugs to specific sites in the body. In both cases, nanotechnology can be used to improve the efficiency and effectiveness of these devices and systems. For example, nanoscale particles can be used to increase the surface area of medical devices, allowing them to be more effective at detecting and treating diseases. Similarly, nanoscale particles can be used to increase the potency of drugs, making them more effective at delivering therapeutic benefits.

In addition to medical devices and drug delivery systems, nanotechnology can also be used to develop new materials and systems for use in the healthcare industry. For example, researchers are exploring the potential of using nanostructures to create new types of tissue scaffolds, which could be used to support and promote the growth of healthy cells. Similarly, nanotechnology can also be used to create sensors that can detect changes in biochemical processes within the body, which could be used to monitor patients more effectively.

The potential of nanotechnology in healthcare is immense.

Using Nanomedicine to Improve Diagnosis and Treatment Outcomes

Nanomedicine has revolutionized the healthcare industry in recent years. Nanomedicine is the use of nanotechnology to improve diagnosis and treatment outcomes. It involves the use of tiny particles, usually less than 100 nanometers in size, to diagnose and treat diseases. Nanoparticles can be engineered to interact with cells and molecules in ways that conventional drugs and treatments cannot, allowing for more accurate diagnosis and targeted treatments.

Nanomedicine has been used in a variety of applications, from the diagnosis of cancer and other diseases to drug delivery and gene therapy. In diagnosis, nanomedicine can be used to detect the presence of specific molecules or pathogens in the body. For example, nanoparticles can be used to detect cancer biomarkers in blood or tissue samples. This allows for earlier diagnosis and more accurate prognosis of the disease. In addition, nanomedicine can be used to image organs and tissues, allowing doctors to identify and monitor diseases at a cellular level.

In drug delivery, nanomedicine can be used to deliver drugs directly to their target sites in the body. Nanoparticles can be designed to bind with specific molecules or cells and deliver drugs to them directly, avoiding many of the side effects associated with traditional drug delivery methods. This also allows for more precise dosing of drugs, which can lead to better therapeutic outcomes.

Gene therapy is another area where nanomedicine has been successfully employed. Gene therapy uses engineered nanoparticles to deliver genetic material directly into cells. This allows for the correction of genetic defects or the introduction of new genes, which can be beneficial for treating genetic disorders. Gene therapy using nanomedicine is still in its early stages, but it has shown promise as a potential treatment for some diseases.

Nanomedicine has also been used to create targeted therapies for cancer and other diseases. By designing nanoparticles that specifically bind to cancer cells, researchers have been able to deliver drugs directly to tumor sites without damaging healthy cells. This has allowed for more targeted treatments that are less toxic and have fewer side effects than traditional treatments.

Overall, nanomedicine has revolutionized healthcare by providing more precise diagnoses and treatments for a variety of diseases. Nanoparticles can be designed to interact with cells and molecules in ways that conventional treatments cannot, allowing for more targeted therapies with fewer side effects. In addition, nanomedicine has enabled gene therapy and other novel treatments that were not possible before its development. As nanomedicine continues to advance, it is likely that it will continue to improve diagnosis and treatment outcomes for many diseases in the future.

With augmented reality technology, the real-time image displayed on the screen is combined with the data obtained by fluoroscopy. The possibility of using this technique in endoscopic surgery has been widely discussed. However, despite the potential of this field, it is still very underdeveloped. One of the factors is the lack of integrated systems that do not need to be supplemented and modified in order to be able to work with augmented images.

The software and technical equipment of the Philips system are designed, among other things, to solve this problem as well. The complex is equipped with an X-ray unit and high-resolution optical cameras, and the image displayed on the screen is already undergoing all the necessary processing. Philips devices using augmented reality technology passed the first preclinical tests at Karolinska University Hospital in Stockholm and at the Medical Center of the Cincinnati Children’s Hospital. According to the findings, published in the journal Spine, the accuracy of the surgeries performed increased by more than 20%.

The developed unit has been highly praised by surgeons. “The new technology gives surgeons the ability to obtain high-quality 3D images of the patient’s spine during surgery and helps plan the optimal course of the intervention. Doctors can place the transpedicular screws more accurately… It is also possible to assess the result of the intervention in 3D directly in the operating room,” commented Dr. Skulason of Landtspitali University Hospital in Reykjavik.

In recent years, however, a new method of analysis, liquid biopsy, based on the analysis of nucleic acids in the blood to detect tumor cells or tumor DNA in the blood, has made a furor in medicine. However, it is worth noting that in terms of pathology, the term “liquid biopsy” is inaccurate because it refers exclusively to a molecular analytic method and not to a biopsy in the pathological sense. The method is based on the fact that tumor cells also release genetic information into the blood, which can be examined for changes that occur in the blood only in very small quantities. Therefore, their detection has only become possible due to the development of new methods for highly sensitive nucleic acid detection, such as “digital drop PCR” or “next/next generation sequencing” (NGS). In addition to peripheral blood, namely plasma, urine, stool, pleural or cerebrospinal fluid can be used as liquid biopsy material.

The liquid biopsy method is used in oncology for purposes such as screening, early cancer diagnosis or assessment of metastatic risks. An important area of use of liquid biopsy is also the identification of target structures for therapy, mechanisms of resistance, and tumor monitoring in general.

Tumor monitoring by liquid biopsy is particularly interesting because it allows both the detection of potentially developing recurrent tumors at a very early stage and the deciphering of their possible altered molecular profile. Thus, if resistance mutations occur during first-line therapy, patient survival could theoretically be significantly increased by switching the targeted therapy.

In addition, complications occur with the classic pacemaker, including infection of the implanted area, displacement of the device, tissue damage, bleeding, and thrombosis. Over the past 5 years, several models have been created to make the device as comfortable and effective for patients as possible.

Using a virus, they injected the algal protein ChR2, which responds to blue light, into the heart cells of experimental rats. It opens ion channels in the membrane in response to the pulse. The experiment showed that the flashes of light can be used to tune the heart rate. However, in order to use ChR2 with the human heart, the problem of light penetration through body tissues must be solved.
• In 2017, researchers from Israel and Canada developed a biological pacemaker using cells that are functionally similar to natural cells that stimulate heart function. They grew them from embryonic stem cells. During the experiment, the transplanted pacemaker cells restored heart rhythm in six out of seven rats.
• In 2019, American engineers developed a generator capable of generating electricity through the contractions of the heart muscle. The current in this case is transmitted to a nearby pacemaker. The developers believe that in the future such a device will make it possible to create a fully autonomous pacemaker that does not require battery replacement.

Statistics and Practice of Pacemaker Use

At least 3 million people around the world live with pacemakers, and about 600,000 devices are implanted in patients each year. In Great Britain alone, 32,902 devices were implanted in 2018-2019 to keep the heart working steadily. Many movie stars, athletes, and politicians live with pacemakers. Cardiomyopathies, bradycardia, heart block, and heart failure can be reasons for the device.
