Step 2: In-silico structural characterization of three peptides—CdPMAP-23, CdPG-3, and CdCATH. Step 3: Laboratory synthesis of the selected peptides. Step 4: In-vitro antimicrobial testing demonstrating suppressed bacterial growth. Step 5: In-vitro hemolysis assessment showing minimal damage to red blood cells.

According to a recent assessment by the World Health Organization (WHO), next-generation influenza vaccines that offer broader and longer-lasting protection than current seasonal formulations could significantly reduce the worldwide impact of influenza. The new WHO Full Value of Improved Influenza Vaccine Assessment (FVIVA), published alongside an article in the journal Vaccine, examines the public health, economic, and policy implications of next-generation influenza vaccines. It also outlines

Health Capsule Arsenic is a naturally found substance present in the environment, including in soil, water, and air. However, prolonged exposure to arsenic can have serious health effects. Many communities still depend on drinking water that contains arsenic at harmful levels. Recent research indicates that reducing arsenic exposure can significantly decrease the risk of dying from cancer and heart-related conditions. The study observed a group of adults in Bangladesh over a period of 20 years.

Health Capsule It's common for patients to experience anxiety before undergoing surgery. However, high stress levels can hinder the body's natural healing process. Increased stress can lead to more inflammation, which is the body's way of protecting itself during injury or illness. Fortunately, there are steps you can take to boost your health ahead of a surgical procedure. This proactive approach is known as prehabilitation. Recent research has found that tailored
