PCOS: The Hidden Struggle Millions of Women Face Polycystic Ovary Syndrome (PCOS) affects 1 in 10 women , yet many don’t even know they have it. It starts with hormones out of balance — the ovaries produce too many androgens (male hormones), throwing off your cycle and causing irregular periods, stubborn acne, unwanted hair growth, thinning scalp hair, and weight gain that refuses to budge. Representational Image (Picture credit: wayhomestudio/freepik) Beyond fertility troubles, PCOS brings real health risks: higher chances of type 2 diabetes, high blood pressure, fatty liver, and heart problems . And the emotional toll is heavy — anxiety, depression, and low confidence often go hand in hand with the physical symptoms. The upside? PCOS can be managed. Losing even 5% of weight can ease symptoms. Birth control pills, metformin, letrozole, and newer treatments like inositol and GLP-1 drugs offer more help. The best care treats both body and mind. With early action and the right suppor...

The ideal weight is typically calculated using the Body Mass Index (BMI) , which takes into account both height and weight to assess whether a person has a healthy body weight. The healthy BMI range is generally considered to be between 18.5 and 24.9 . To calculate your ideal weight range, you can use the following formula for BMI: BMI = Weight (kg) / (Height (m)²) Here's a general guideline for calculating ideal weight based on BMI: For a BMI of 18.5 (lower end of healthy weight) : Ideal weight (kg) = 18.5 × (height in meters)² For a BMI of 24.9 (upper end of healthy weight) : Ideal weight (kg) = 24.9 × (height in meters)² For example, if your height is 1.75 meters: For the lower range (BMI 18.5), the weight would be 18.5 × (1.75)² = 56.5 kg. For the upper range (BMI 24.9), the weight would be 24.9 × (1.75)² = 76.4 kg. This gives an ideal weight range of 56.5 kg to 76.4 kg for a height of 1.75 meters. You can apply this formula based on your height...

Article by: Arya Bandyopadhyay Dated: 27th April, 2025 This deep evolutionary connection provides new insight into why octopuses, despite being invertebrates, display advanced and sophisticated behaviors typically associated with vertebrates. Built by evolution. Split by fate. Connected by intelligence. Credits: Visual fusion crafted with AI | Honoring the mind-bending legacy of cephalopods and humankind. Ancient Evolutionary Link: New research suggests that octopuses and humans may share an ancient evolutionary connection, offering an explanation for the remarkable intelligence of cephalopods. Common Ancestor: Both species could trace their cognitive complexity back to a common ancestor that lived around 518 million years ago. The Role of MicroRNAs (miRNAs): MicroRNAs (miRNAs) are small regulatory molecules that control how genes are expressed. A study led by Nikolaus Rajewsky at the Max Delbrück Centre for Molecular Medicine revealed that octopuses and other soft-bodied cephalopods e...

A Medical First: Chinese Scientists Reverse Type 1 Diabetes Using Patient's Own Stem Cells -Article by Arya Bandyopadhyay Abstract In a pioneering clinical achievement, researchers in China have successfully reversed Type 1 diabetes in a 25-year-old woman through an autologous stem cell transplant. Using chemically induced pluripotent stem cells (CiPSCs) derived from her fat tissue, scientists developed insulin-producing islet-like clusters that were transplanted into her abdominal muscle. Within 75 days, the patient regained independent insulin production, maintained normal blood glucose levels, and was free from insulin injections—a sustained result still observable over a year later. This breakthrough suggests a major step forward in regenerative medicine and personalized therapies for autoimmune diseases such as Type 1 diabetes, although further research is necessary to determine long-term efficacy and immune tolerance.

Abstract Artificial sweeteners like saccharin, commonly used as sugar substitutes, are revealing surprising capabilities in combating antibiotic-resistant bacteria. Recent research indicates that saccharin and similar compounds, such as acesulfame-K and sucralose, can inhibit the growth of multidrug-resistant pathogens like Acinetobacter baumannii and Pseudomonas aeruginosa . These sweeteners disrupt bacterial biofilm formation and motility, and they can enhance the effectiveness of existing antibiotics by increasing bacterial membrane permeability, leading to cell lysis. Notably, acesulfame-K demonstrated potent antimicrobial activity in ex vivo wound models, suggesting potential therapeutic applications. ​ However, there's a complex side to this narrative. Studies have shown that artificial sweeteners can also promote the spread of antibiotic resistance genes. They do this by increasing bacterial cell membrane permeability and stimulating the expression of genes involved in D...

A dietary swap that could lengthen your life? Swapping butter for plant-based oils could trim your risk of early death by 17%, according to a new study. “Even cutting back butter a little and incorporating more plant-based oils into your daily diet can have meaningful long-term health benefits.”  -Daniel Wang, Brigham and Women’s A study from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute found that replacing butter with plant-based oils like soybean, canola, and olive oil could reduce the risk of premature death by up to 17% . Analyzing data from over 200,000 participants tracked for 30+ years, the research showed that higher butter consumption was linked to a 15% increased risk of death, particularly from cancer and cardiovascular disease, while greater use of plant-based oils was associated with a 16% lower risk. Published in JAMA Internal Medicine, the study highlights that swapping just 10 grams of butter daily with plant oils could ...

Abstract : The Lewis blood grouping system, like the ABO system, plays a crucial role in shaping the human gut microbiome through genetically determined fucosylated glycans expressed on mucosal surfaces. These glycans act as microbial binding sites and nutrient sources, influencing the colonization and composition of gut bacteria. Secretor status, governed by FUT2 and FUT3 genes, determines the presence of Lewis antigens, which affects microbial diversity, immune interactions, and susceptibility to infections and inflammatory diseases. This abstract explores how host genetics, particularly the Lewis and ABO blood group systems, contribute to the dynamic and evolving relationship between humans and their gut microbiota.

  🩸 Is Blood Sterile?  -A Microbiologist’s  Take on the Pristine River Within Have you ever wondered what's really flowing through your veins besides red cells and life itself? We often hear how blood carries oxygen, nutrients, and hormones — but what about bacteria or viruses? Could they be cruising through your bloodstream too? Let’s uncover the mystery:  Is blood sterile? 🧬 Abstract Yes, blood is normally sterile — meaning that under healthy conditions, it does not contain any microorganisms such as bacteria, fungi, or viruses. Healthy blood = sterile Microbes in blood = potential medical emergency 🔬 Why Is Blood Normally Sterile? Under normal, healthy conditions, blood is completely sterile. This means it doesn't contain any bacteria, fungi, or viruses. Your body is built to keep the bloodstream a super-secure, clean highway — no trespassers allowed. Blood travels everywhere — your brain, heart, kidneys, even your toes. A single microbe could hitchhike its way...
