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.

Scientists Test Battery Powered by the Body’s Oxygen

Medical implants such as pacemakers and gastric stimulators have improved our lives, but the batteries in these devices eventually run out and require surgery to replace them.

It raises a futuristic question: what if there was a way to avoid cutting a patient’s body open to replace a battery?

A team of Chinese scientists have come up with a possible method to pull that off by developing an implantable battery that uses oxygen already inside the human body to continuously power itself up.

Biomolecular Bonsai: Controlling the Pruning and Strengthening of Neuron Branches in the Brain

Researchers identify molecular cues that make developing neurons remodel their connections.

At this very moment, the billions of neurons in your brain are using their trillions of connections to enable you to read and comprehend this sentence.

Now, by studying the neurons involved in the sense of smell, researchers from Kyushu University’s Faculty of Medical Sciences report a new mechanism behind the biomolecular bonsai that selectively strengthens these connections.

To observe photoswitches, stick on a platinum atom

Advances with photoswitches could lead to a smartphone that’s soft and flexible and shaped like a hand so you can wear it as a glove, for example. Or a paper-thin computer screen that you can roll up like a window shade when you’re done using it. Or a TV as thin as wallpaper that you can paste on a wall and hardly know it’s there when you’re not watching it.

Photoswitches, which turn on and off in response to light, can be stitched together to replace the transistors used in that control the flow of the electric current.

Commercial silicon transistors are brittle, nontransparent, and typically several microns thick, about the same thickness as a . In contrast, photoswitches are one or two nanometers, about 1,000 times thinner. They can also be mounted on graphene, a transparent, flexible material.

Cancer vaccine for dogs appears to nearly double survival rate

Yale researchers have developed a cancer vaccine for dogs that nearly doubles their 12-month survival rate — and it might be a powerful treatment for humans with cancer, too.

Sick as a dog: In 2011, the FDA approved the first ever cancer immunotherapy — a treatment that supercharges the immune system to fight cancer — and today, oncologists have dozens of powerful immunotherapies in their arsenal, with more coming every year.

That’s not the case if the oncologist happens to treat dogs instead of people, though.

Breaking ground in genome-editing technology

Genomes are the blueprints of living creatures; chromosomes and genes within all our cells encode information about life. Genome editing technology that can change these chromosomes and genes has developed rapidly. From drug development and gene therapy, improvements to crops and livestock, to creating useful microorganisms to replace petroleum, this technology has started to have a significant impact on our societies.

Professor NISHIDA Keiji (Graduate School of Science, Technology and Innovation) has developed a new genome editing technology and established a business venture based on his research findings. He is on the front lines of genome editing in both business and research.
