This drug-delivering contact lens will heal corneal wounds faster

Conventionally, corneal abrasion patients wear a clear, oxygen-permeable bandage contact lens for seven to 10 days but this treatment does not ensure the drug remains in the eye for sustained treatment, according to a statement by the University of Waterloo.

This new lens material was developed with the ambition to address the limitations of current methods for treating corneal abrasions. The contact lens material is derived from gelatin methacrylate, a collagen by-product. Collagen is a protein naturally found in the eye and is involved in the wound-healing process but it’s too soft and weak to perform as an appropriate contact lens material.

Dr. Evelyn Yim, an associate professor of chemical engineering at the University of Waterloo, found a way to transform gelatin methacrylate into a biomaterial ten times stronger than collagen, the statement revealed.

Scientists Find Human Brains Are Getting Larger and Larger

If someone tells you that you have a big head, take that as a compliment.

Humankind’s brains have apparently gotten bigger and bigger over the years, according to a team of scientists, who are surmising that bigger brains may stave off dementia as folks age.

An international team of researchers, led by the University of California Davis Health, arrived at this finding after studying the MRIs of people starting with those born in the 1930s, all the way through the 1970s.

CSIR-NIIST unveils innovative technology for safe biomedical waste management

Thiruvananthapuram: CSIR-National Institute for Interdisciplinary Science and Technology (CSIR-NIIST) has pioneered a groundbreaking technology for the safe, sustainable, and cost-effective management of biomedical waste, marking a significant milestone as the first of its kind in the country.

This innovative technology was unveiled at the Biomedical Waste Management Conclave, a one-day event hosted at the CSIR-NIIST campus in the city on March 26.

According to UNI, Dr M Srinivas, Director, AIIMS New Delhi, inaugurated the meet, which was presided over by Dr N Kalaiselvi, Secretary, DSIR and Director General, CSIR, through videoconferencing.

What are the Signs & Symptoms of Stomach Cancer?

Learn more about the role of your stomach and learn more about the signs and symptoms of stomach cancer that you should be aware of.

The stomach is part of the body’s digestive system, located in the upper abdomen.

It acts as a temporary storage area for food before being mixed and broken down and passed through the rest of the upper gastrointestinal system.

Stomach cancer – sometimes also referred to as gastric cancer – occurs when abnormal cells in the stomach grow out of control. This may also occur in the junction where the stomach meets the oesophagus.

Unlike other cancers, there is no early detection test for stomach cancer.

The symptoms are often vague and can be similar to other medical conditions – so it’s important for you to see your GP for a review if you experience symptoms that are unusual for you or persistent.

Breakthrough Therapy Obliterates Deadly Brain Tumor in Days

Brain scans of a 72-year-old man diagnosed with a highly aggressive form of cancer known as a glioblastoma have revealed a remarkable regression in his tumor’s size within days of receiving an infusion of an innovative new treatment.

Though the outcomes of two other participants with similar diagnoses were somewhat less positive, the case’s success still bodes well for the search for a way to effectively cure what is currently an incurable disease.

Glioblastomas are typically about as deadly as cancers can get. Emerging from supporting cells inside the central nervous system, they can rapidly develop into malignant masses that claim up to 95 percent of patient lives within five years.
