New and Revolutionary Treatment for Bacterial Infection

By Patrick Yang ’20 Bronchiectasis occurs when the lung’s bronchial tubes are permanently damaged or inflamed, leading to chest pain, coughing up blood, and large production of mucus. These damaged lung walls also make bronchiectasis patients more prone to chronic infection and, specifically, Pseudomonas aeruginosa lung infections, which increase mortality rates. However, previous research has…

Vitamin C Enhances Cancer Therapy

By Patrick Yang ’20 Ascorbate, or vitamin C, is a potential anti-cancer agent when paired with chemotherapy. Scientists hypothesize that ascorbate’s curative powers stem from its ability to produce hydrogen peroxide, which reduces iron to form free radicals – highly reactive molecules that damage DNA and cause cell death. Since aggressive cancers have unusually large…

Maternal Vaccination’s Role in Infant Survival

By Patrick Yang ’20 Pertussis, more commonly known as whooping cough, is a life-threatening infection in infants that can easily be prevented through vaccination. However, infection rate has been increasing over the past several years. And since the DTaP vaccine for pertussis is administered after two, four, and six months of age, an infant is…

Scientists Create First Ever Artificial Embryo

By Patrick Yang ’20   Embryo development has been a very limited and sanctioned field of research due to concern for the pregnant mother. Although safety is a priority for live subjects, research in this area could improve understanding of optimal prenatal conditions, as well as the molecular interactions between embryonic stem cells. Researchers have…

Figure 1. Asthma’s exaggerated contraction of airways is due to a lack of smooth muscle relaxant.

Airway Smooth Muscle Relaxant Finally Identified

By Patrick Yang ’20 Asthma, characterized by its iconic inhalers and abrupt episodes of coughing and wheezing, affects approximately 334 million people worldwide. The inflammatory disease is caused by the prolonged contraction of airway smooth muscles, which triggers difficulty with breathing. Despite our understanding of asthma’s symptoms, the mechanism behind asthma is still a mystery.…
