The Evolution and Ethics of Cloning: A Comprehensive Overview

Reading Time: 5 minutes The Evolution and Ethics of Cloning: A Comprehensive Overview Cloning is referred to as a technology in which a group of cells, or an organism is replicated to generate an identical copy. The technology of cloning helps create genetically identical copies of organisms. In this exploration, we delve into the historical roots of cloning, its diverse applications, and the ethical debates it has ignited. From the landmark moment of Dolly the sheep’s birth to the potential future of human reproductive cloning, we unravel the past, present, and future of this fascinating technology. Join us as we navigate the complex landscape of cloning, from its scientific breakthroughs to the ethical considerations that shape its evolution.   Types of artificial cloning:  Therapeutic cloning:  Therapeutic cloning is referred to as a cloning technology wherein, the nuclear transfer is used to provide tissues, cells, and organs for a patient needing supplementation or replacement of the damaged or diseased tissue.  This involves generating an embryo only to manufacture embryonic stem cells which are used in understanding diseases.   Reproductive cloning:  Reproductive cloning produces genetically identical organisms. Two methods used in reproductive cloning are Somatic cell nuclear transfer (SCNT) and Embryo splitting. Identical twins are said to be the most common examples of natural clones. Reproductive cloning produces whole duplicated organisms.   Gene cloning:  Gene cloning or DNA cloning refers to the cloning of genes. In this, a copy of genes or DNA is produced. Gene cloning includes different processes from that of biomedical or reproductive cloning. Historical background:  Earliest reference and the first demonstration of embryo twinning:  The earliest talk about cloning can be traced back to the 19th century. In the year 1885, Hans Driesch described the ability of blastomeres of two-cell sea urchins to be separated and formed two complete embryos from each blastomere.   Birth of cloning:  In the year 1902, Hans Spemann employed the earlier discovered method to clone salamanders. Spemann’s experiment described that the method worked for complex organisms – however only up to a specific developmental stage.  Later on in the year 1928, Spemann conducted nuclear transfer for the first time. This time a noose was used to separate a cell from the embryo. This experiment demonstrated that the early embryonic cell nucleus can be utilized in the complete development of the salamander. The proposition of nuclear transfer became the fundamental technique for cloning. This experiment presented the ability to manipulate the nuclei of the cell and that the genetic material can be transferred to another organism.   Cloning of frogs:  Briggs and King successfully used nuclear transfer and successfully cloned frogs from a frog embryo cell to an enucleated egg cell. This experiment described the ability to produce an entire organism using somatic cell nuclear transfer.   The breakthrough of Dolly:  The birth of Dolly the sheep was known to be the most vital moment in the history of cloning. In 1996 Ian Wilmut and Keith Campbell made history by successfully cloning the first mammal. A nucleus was transplanted from the udder cells of an adult sheep to an enucleated cell. One embryo out of 277 attempts was carried by a surrogate mother for gestation. Cloning was brought to light and into the public eye by the well-known lamb named Dolly. This breakthrough utilized somatic cell nuclear transfer and showcased the potential new possibilities in regenerative medicine and reproductive biology. Later on, multiple organisms were cloned including mice and camels.   Cloning and legends:  Most often cloning is also linked with Hindu mythology which mentions the concept of reincarnations, births, and rebirths. Where an individual goes through the cycle of births experiencing each life. This idea correlated to the idea of cloning where the genetic material of an animal is replicated to create a new body.   Applications and the future:  Cloning is the means to replicate the present complementary or favourable characteristics in livestock such as high production of milk, growth efficiency, etc. This helps produce organisms with specific genetic modifications. Animals such as mice are cloned to understand biological mechanisms in research.  Human reproductive cloning would help infertile couples have children that are genetically identical to them. People who require transplants to treat their children’s disorders and hence want to collect genetically identical tissue from that of the cloned fetus. Cloning can also be immensely useful in the conservation and de-extinction of endangered species. Attempts have been made to clone organisms such as the gaur ox, and Macaque monkey using nuclear transfer. Xenotransplantation is another application of cloning. This enables the transplant of cells, tissue, or organs from one species to another. Ethical debates: Along with the benefits the technology of cloning offers society today as well as cloning for medical research, ethical debates arise with the possibility that one day a cloned human may be born. However, no such attempts have been confirmed or acknowledged.   Cloning for reproductive purposes raises concerns about the commodification of life and the potential abuse of cloning technology. Many countries imposed regulations and restrictions on experiments surrounding cloning after the birth of Dolly. Issues regarding the uniqueness and individuality of human beings have been raised as it involves creating a replica of an individual. The cloning process has been found to have significant health implications for cloned animals, including a higher risk of genetic abnormalities and health complications.  Apart from this some other issues surrounding cloning involve potential health risks, fear of genetic abnormalities, social and psychological impacts, etc.   Conclusion: The cloning technology continues to advance. The exploration has still been going on considering the ethical implications. The journey of cloning has been filled with curiosity and scientific breakthroughs. To make use of cloning technology in the future for advancement in human health and diseases, we must address the fears associated with cloning. A new narrative that supports the applications and challenges surrounding the technology of cloning must be created. As the future guarantees advancements and discoveries. Author: Ms Sanika Pande

Biotin: Understanding Its Importance for Health and Well-Being

Reading Time: 5 minutes Biotin: Understanding Its Importance for Health and Well-Being The vitamin biotin, commonly referred to as vitamin B7 or vitamin H, is a water-soluble vitamin. The name “vitamin H” originates from the German words ‘Haar and Haut,’ which means hair and skin, highlighting its significance for these aspects of health. Biotin naturally occurs in various food items such as eggs, nuts and certain vegetables. It’s also commonly included in dietary supplements, often marketed for its potential benefits in promoting healthy hair and skin, as well as supporting overall well-being.   The role of Biotin in our body:  Biotin plays a vital role in the metabolism of fats, carbohydrates, proteins, etc. It helps convert these macronutrients into energy that the body can use. Also, biotin is responsible for maintaining cardiovascular health, and proper nerve functioning.  Biotin is often associated with promoting the health of hair, nails, and skin. It is a common ingredient in many beauty supplements.  Biotin is essential in the regulation of genes (as it modifies the activities of transcription factors), histone modifications, and cell signalling.  Biotin is considered to be important in breaking down macronutrients, it is involved in processes such as the synthesis of fatty acids, breakdown of amino acids, and glucogenesis.  Apart from this, biotin plays a key role in lactation, pregnancy, and regulation of blood sugar levels in type 2 diabetic patients. Sources of Biotin: Biotin is present in a variety of plant and animal-based food items, some of which include:  Eggs: The egg yolk is particularly renowned for its high biotin content. However, it’s advisable to cook them as avidin in raw egg whites can interfere with biotin absorption. Spinach: Spinach is not only a good source of biotin but also offers a variety of other vitamins (such as Vitamin A, C, and Folic acid) and minerals (such as Iron, Calcium, and potassium).  Sweet potatoes: Rich in antioxidants, fibre, vitamins, and minerals, sweet potatoes are a nutritious source of biotin Avocados: These are high in biotin and provide vitamin E, which is beneficial for skin and hair health. Organ meats: The liver, particularly chicken liver, is a potent source of biotin. Just 3 ounces of cooked chicken liver can provide a significant amount of biotin. Nuts: Nuts, such as almonds, peanuts, and walnuts, contain biotin and can be included in your diet. Along with these some other food items such as mushrooms, legumes, salmon, yeast, and dairy products are rich in biotin.   What are the normal biotin levels? The normal ranges for biotin levels in the blood serum is approximately: Adults: 133-329 picomoles per litre (pmol/L) Children: 157-425 pmol/L On average in adults, the normal urine biotin concentration must be around 18-127 nmol/24hrs. Biotin Deficiency The biotin deficiency is relatively rare in healthy individuals because biotin is found in a variety of foods, and the body requires only a small amount of it. However, certain medical conditions or genetic factors can lead to biotin deficiency or impaired biotin metabolism. An unusual decrease in biotin excretion through urine signals a deficiency in biotin. Similarly, an elevated excretion of 3-hydroxyisovaleric acid (above 3.3 mmol/mol creatinine) or 3-hydroxyisovalerylcarnitine (above 0.06 mmol/mol creatinine) is indicative of reduced MCC (3-methylcrotonyl-CoA carboxylase) activity, suggesting a biotin deficiency.   What are the signs and symptoms of Biotin deficiency? The Symptoms such as hair fall, conjunctivitis, brittle nails, and rashes, may indicate biotin deficiency. In severe cases of deficiency, In adults, symptoms may include seizures, skin infections, fragile nails, and neurological issues like depression, lethargy, hallucinations, and tingling sensations in the extremities. In infants, symptoms may manifest as hypotonia, lethargy, and developmental delays Serum concentrations of biotin and its metabolites can be increased by administration of oral doses.   Recommended Amounts There’s no Recommended Dietary Allowance (RDA) for biotin because there isn’t sufficient evidence to determine a daily requirement for most healthy individuals. Adolescents and adults are often advised to take between 30 to 100 micrograms (mcg) of biotin daily. Supplements and gummies:  The significance of biotin was first noticed when rats with the absence of biotin in their diet showed disorders such as neuromuscular dysfunction, dermatitis, and alopecia.  In case suffering from a biotin deficiency, supplements can help level up the required concentrations of biotin in the body. A wide range of dietary supplements for biotin are available, including supplements that contain just biotin, and supplements containing various combinations of vitamins and B-complex. However, it is important to choose according to the individual’s deficiencies and requirements.  Biotin gummies are a popular dietary supplement option for individuals looking to increase their biotin intake. Biotin gummies are easy to take and often more enjoyable than swallowing pills or capsules.   Biotin for skin and hair health:  In a recent decade, biotin has become commercially popular for its claimed benefits on skin, nails, and hair health. Biotin is an important nutrient that helps with the production of keratin.  Hair Health: Studies reveal that low levels of biotin can cause hair loss.  Biotin supplements are often prescribed for the strengthening of hair. Cosmetic products also tend to contain biotin as an alternative supplement. Biotin is known to improve the elasticity of hair and reduces brittleness which prevents the strands from breakage. It has been reported that people using biotin-enriched hair products experienced thickness in hair, texture, and overall hair health.    Skin Health: Biotin is said to promote radiant complexion as it is significant in the production of fatty acids which are responsible for maintaining healthy skin cells. And speeds up the process of regeneration supporting the collagen protein which imparts elasticity to the skin. However, the complete role of biotin in maintaining healthy skin has not been elucidated by scientists. The influence of vitamins on the skin may be associated with the effect on the metabolism of fat. Despite the rising craze for biotin in the media, only a small amount of literature is found to support the biotin claims for skin and hair health.   Conclusion:  Biotin plays a vital role in

The Harmonious Duel Between Music and Pain Perception

The Harmonious Duel Between Music and Pain Perception

Reading Time: 8 minutes The Harmonious Duel Between Music and Pain Perception | The Harmonious Duel Between Music and Pain Perception Gate Control Theory of Pain Perception: The gate control theory, a foundational concept in pain physiology, suggests that the spinal cord acts as a “gate” regulating the flow of pain signals to the brain. When non-painful sensory input (such as tactile or auditory stimuli) is introduced, it competes for the brain’s attention, thereby “closing the gate” to the transmission of pain signals. This neural phenomenon highlights the intricate interplay between sensory modalities and their potential to modulate pain perception. The Gate Control Theory, initially proposed by psychologists Ronald Melzack and Patrick Wall in 1965, is a widely accepted model that explains how pain signals are processed and perceived by the brain. This theory revolutionized the understanding of pain perception and has significant implications for pain management, including its application in conjunction with music therapy. According to the Gate Control Theory, pain perception is not solely determined by the intensity of a painful stimulus. Instead, it emphasizes the role of the central nervous system in regulating the flow of pain signals to the brain. The spinal cord is considered a “gate” that can either amplify or inhibit the transmission of pain signals, depending on the interaction between different types of sensory input. Non-painful sensory input, such as touch, pressure, or vibration, can stimulate large-diameter nerve fibres known as A-beta fibres. These fibres carry signals related to non-painful sensations and can “close the gate” to pain transmission. When these non-painful sensory signals are activated, they compete for attention in the spinal cord with smaller-diameter pain fibres (A-delta and C fibres). As a result, the gate is partially closed, reducing the perception of pain. The Gate Control Theory suggests that by stimulating non-painful sensory pathways, one can modulate pain perception. This concept has been applied in various pain management techniques, including massage therapy, heat therapy, and transcutaneous electrical nerve stimulation (TENS). The Gate Control Theory has been extended to the field of music therapy, explaining how music can serve as a competing stimulus to pain signals. The sensory engagement and emotional resonance elicited by music can activate large-diameter nerve fibres, thus influencing pain perception. When an individual listens to music, various sensory and emotional components are simultaneously engaged. The rhythmic patterns, melodies, harmonies, and emotional qualities of music stimulate multiple sensory pathways. These sensory pathways can activate A-beta fibres, which, in turn, compete for the brain’s attention with the pain signals carried by smaller-diameter fibres. As a result, music therapy can have a diversionary effect, redirecting the brain’s focus away from pain sensations. Moreover, the emotional and physiological responses triggered by music, such as the release of endorphins (natural pain-relieving chemicals) and the modulation of autonomic nervous system activity, contribute to the overall reduction in pain perception. Incorporating music therapy as part of pain management strategies aligns with the principles of the Gate Control Theory by harnessing the power of sensory engagement and attentional diversion to alleviate pain and promote well-being. Music as a Competing Stimulus: In the context of pain management, music serves as a powerful competing stimulus that can effectively engage the brain’s attention, diverting it from pain signals. The complex sensory experience of music involves various brain regions, leading to a phenomenon known as “attentional diversion.” As the brain focuses on the rhythm, melody, and emotional nuances of music, it allocates fewer cognitive resources to processing pain signals, ultimately resulting in reduced pain perception. Research on Music Therapy and Pain Reduction: Numerous studies have explored the analgesic effects of music therapy during medical procedures. One notable study conducted in a clinical setting found that patients undergoing minor surgical procedures experienced significantly lower pain scores when exposed to carefully selected music. The rhythmic patterns and emotional resonance of the music contributed to an overall decrease in perceived pain intensity and an improved subjective experience. Moreover, research has revealed that the physiological responses induced by music, such as the release of endorphins and the modulation of autonomic nervous system activity, further contribute to pain relief. The synchronization between musical tempo and heart rate has been demonstrated to create a calming effect, potentially leading to a decrease in perceived pain and anxiety. The Role of Personalized Music Selection: Personalized music therapy plays a pivotal role in pain management. Tailoring musical choices to an individual’s preferences can enhance the analgesic effect. When patients are engaged with music that resonates on a personal and emotional level, the diversionary and emotional components of pain modulation are maximized. Clinical Applications and Future Perspectives: The integration of music therapy as an adjunctive approach to pain management holds promise across a spectrum of medical settings. From preoperative interventions to postoperative recovery, the utilization of music as an analgesic tool aligns with the principles of patient-centred care. However, further research is essential to elucidate the precise mechanisms by which music impacts pain perception and to optimize protocols for specific patient populations.

Understanding Oligohydramnios: Low Amniotic Fluid in Pregnancy

Reading Time: 6 minutes Oligohydramnios: Causes, Diagnosis, Management, and Potential Complications Oligohydramnios: Causes, Diagnosis, Management, and Potential Complications An Overview Oligohydramnios is a condition marked by an insufficient amount of amniotic fluid, a crucial protective and nourishing substance surrounding the developing fetus within the womb. In India, where maternal and fetal health remains critical public health priorities, the prevalence and implications of oligohydramnios have garnered increased attention. This article aims to provide a comprehensive understanding of oligohydramnios, covering its diagnosis, underlying causes, management strategies, and potential complications it may pose. An Overview Oligohydramnios is a condition marked by an insufficient amount of amniotic fluid, a crucial protective and nourishing substance surrounding the developing fetus within the womb. In India, where maternal and fetal health remains critical public health priorities, the prevalence and implications of oligohydramnios have garnered increased attention. This article aims to provide a comprehensive understanding of oligohydramnios, covering its diagnosis, underlying causes, management strategies, and potential complications it may pose. Did You Know? Oligohydramnios is observed in approximately 1-5% of full-term pregnancies Globally. Nevertheless, its prevalence escalates to over 12% in Post Term Pregnancies. Oligohydramnios contributes to approximately 6.5% of all Stillbirths in Low and Middle-income Nations. What Is Amniotic Fluid? During pregnancy, the liquid enveloping the fetus inside the uterus is referred to as amniotic fluid. Its essential functions include:   Facilitating Development: Amniotic fluid supports the proper growth of the fetus’s muscles, bones, organs, lungs, and digestive system. It also contributes to maintaining their temperature and safeguarding the baby. Lung Maturity: The fluid is vital for the maturation of the fetal lungs. Fetal Movement: Enabled by the cushioning effect of the fluid, the fetus moves and changes positions within the womb. This fluid aids in rotation and ensures a cushioning effect, protecting the fetus from external impacts. Umbilical Cord Protection: The amniotic fluid serves to prevent compression of the umbilical cord, which is the connection between the baby and the uterine wall. This safeguarding mechanism is crucial for the baby’s well-being.   Amniotic Fluid Volume Throughout Pregnancy: The production of amniotic fluid begins shortly after conception, around 12 days after fertilization, when the amniotic sac starts forming. Maternal plasma primarily composes the fluid initially. Around 20 weeks of gestation, the fetus’s urine becomes a primary source of the amniotic fluid. This is why the quantity of amniotic fluid reflects fetal urine production, providing insight into the proper development of the baby. Throughout the various stages of pregnancy, the volume of amniotic fluid undergoes changes influenced by different sources:   In the first trimester, amniotic fluid primarily consists of fetal lung secretions, maternal plasma crossing fetal membranes, and contributions from the placental surface. The second-trimester witnesses a shift as fetal kidneys become the primary source, producing urine that significantly contributes to the amniotic fluid volume. Amniotic Fluid Levels:  Amniotic Fluid increases until about 36 weeks, then decreases significantly after 40 weeks. At around 34 weeks, the volume is approximately 800 Milliliters, and by 40 weeks, it is around 600 Millilitres. If the Amniotic Fluid Volume is less than 500 Milliliters between 32-36 weeks of Gestation, it is referred to as Oligohydramnios. Symptoms of Oligohydramnios Oligohydramnios symptoms often go unnoticed by pregnant women, but doctors may suspect it if:   Fluid leaks from the vagina continuously. The uterus is smaller or not growing as expected. Fetal movements are reduced. Maternal weight gain is insufficient.  A history of low amniotic fluid in a previous pregnancy raises the risk of developing Oligohydramnios in subsequent pregnancies.   Causes of Oligohydramnios Oligohydramnios can arise due to factors involving the fetus, placenta, or mother. Given that amniotic fluid is mainly fetal urine, low volume (oligohydramnios) usually suggests reduced fetal urine or leakage of amniotic fluid from the uterus. Fetal Factors: Chromosomal abnormalities, including Down Syndrome. Fetal renal conditions such as agenesis, cystic renal diseases, and posterior urethral valves. Events such as intrauterine death, post-term pregnancy, or early rupture of membranes. Intrauterine Growth Restriction (IUGR) and amnion nodosum. Placental Factors: Conditions like placental abruption, thrombosis, or infarction. Stuck twin syndrome, leading to diminished amniotic fluid in one fetus. Maternal Factors: Reduced blood supply to the placenta due to conditions like preeclampsia, hypertensive disorders, nephropathy, or thrombophilia. Specific medications, including ACE inhibitors, NSAIDs, or trastuzumab. Infections such as TORCH, gastrointestinal tract infections, and chronic diarrhoea. Diagnosis of Oligohydramnios:  Oligohydramnios is typically diagnosed through ultrasound examinations, focusing on two key measurements:  An amniotic fluid index (AFI) of less than 5cm  Single deepest pocket (SDP) measurement of less than 2cm Upon diagnosis, a thorough investigation of the maternal history and potential underlying causes is crucial to ensure the health and well-being of both the mother and the developing fetus.   several tests aid in evaluation: 1. Nitrizine and Ferning tests for premature rupture of membranes (PROM):  premature rupture of membranes (PROM) refers to the breaking of the amniotic sac before labour begins. nitrizine and ferning tests are techniques used to assess whether amniotic fluid is leaking.   2. Fetal anomaly assessments through ultrasound and, if required, MRI scans:  Ultrasound scans are commonly used during pregnancy to assess fetal development and detect any potential anomalies.   3. Alpha-Fetoprotein (AFP) checks, along with placental and blood tests:  Alpha-fetoprotein (AFP) is a protein produced by the fetus and is found in the mother’s blood. AFP levels can provide information about the health of the fetus.   Treatment of oligohydramnios: Effective treatment approaches may include: Amnioinfusion: Introducing 200ml of saline into the amniotic sac to increase the levels of amniotic fluid.  Promoting oral hydration to enhance amniotic fluid levels.  Surgical interventions may be required in a few cases to address the underlying issues, such as blockages in the urinary tract, to ensure proper urine flow and subsequent amniotic fluid production.  Monitoring fetal well-being and managing the condition Regular non-stress tests (NST) or SDP measurements: non-stress tests (NST) and single deepest pocket (SDP) measurements are monitoring techniques used to assess the well-being of the fetus. It is recommended to plan for delivery between 36-37 weeks. this is to

Ink and Introspection: Navigating the Art and Awareness of Tattoos

Reading Time: 6 minutes Ink and Introspection: Navigating the Art and Awareness of Tattoos Tattoo: An Imprint of Identity and History A Tattoo is referred to as a mark, an image, or a phrase that is intentionally and permanently fixed on the skin. This is usually done by a specific type of ink inserted into the epidermis of the skin. Throughout the annals of time, humanity has woven a narrative of skin-deep significance. For millennia, tattoos have been more than pigments; they are the brushstrokes of identity, a tableau of beliefs and emotions etched into the skin’s canvas. These indelible imprints, painstakingly embedded into the epidermal layers, evoke tales of status, convictions, love, embellishment, and sometimes even retribution. The origin of tattooing traces back through the ages, a window into cultures that have painted their stories across generations. A reflection of the human desire to etch one’s mark upon the world, tattoos have evolved from primitive tools to intricate designs woven with modern precision. They transcend the surface, weaving threads of heritage, forging connections with ancestral echoes, and resonating with the resonance of personal narratives. So, let us peer into the intricate designs that adorn the flesh, acknowledging the myriad reasons individuals bear these marks. The Earliest Testimony of Tattoos: Otzi the Iceman Among the annals of ancient history, one enigmatic figure stands as a frozen witness to the ancient art of tattooing. Europe’s famous mummy, Otzi or the Iceman was discovered in the Alps by German hikers in 1991. Approximately 5200 years ago, Otzi walked the rugged landscapes of Tyrol, leaving behind a legacy etched in ice and ink. After his death, the body and the tattoos were preserved in ice. Tattoos on the mummy were of ceremonial, religious, and ritualistic significance. The mummy was found to have 61 tattoos on the entire body. This frozen time capsule paints a vivid portrait of a world long gone. As we gaze upon the mummy adorned with symbols of yore, we find ourselves transported to an era of reverence and symbolism, where ink and skin harmoniously converged to inscribe stories of the human experience. Otzi’s legacy resonates as a captivating archaeological find and an invitation to peer into the lives of those who walked the Earth millennia ago. Far from mere adornments, his tattoos evoke a saga of rituals, connections, and echoes of beliefs that transcend time. In the ancient ink etched upon his skin, we encounter a bridge that unites us with our ancestors, a testament to humanity’s enduring curiosity and artistic expression. Mindset behind the Tattoo Culture: Earlier Beliefs Earlier the tattoos were not as much appreciated. Society still thinks of tattoos as a child’s non-traditional and rebellious mentality. Even today, in pockets of conservative thought, tattoos evoke associations with subcultures like gangsterism and mafia, reflecting a discord between ink and societal norms.

Health Risks Associated with Tattoos Within the realm of body art, a world of self-expression and transformation exists, intertwined with a web of health considerations that deserve our attention. Hepatitis Concerns: The unhygienic aspects of having a tattoo are often ignored by people. Alarming instances of hepatitis, particularly Hepatitis C, have emerged as a consequence of the growing popularity of tattoos. Chronic diseases like Hepatitis C can be transmitted through contact with contaminated blood. Tattoo parlours are home to many such life-threatening diseases. Increased Vulnerabilities to Infection: In the pursuit of the perfect design, it’s crucial to remember that improper care can quickly transform an artful expression into an infection-prone area.
