Researchers find a New Class of Biomarkers to Predict Treatment Outcomes in Cancer Patients

Researchers find a new class of biomarkers to predict treatment outcomes in cancer patients
Cancer is the result of the uncontrolled division and spread of cells into surrounding tissue. Recently researchers have begun to focus on biomarkers as a source of information about different cancers, how they work in the body, and how they can be fought.

One of the big reasons that cancer is difficult to treat is that patients respond to treatments differently, and these differences can rarely be anticipated. In most cases, determining whether and how a patient will respond to any given therapy requires administering it to the patient and then waiting and watching. That is a lot of pressure for researchers and physicians and a lot of risk for cancer patients, and added expense.

If a patient’s response were predictable, optimal thera...

Helping ‘Good’ Gut Bacteria and Clearing out the ‘Bad’ – all in one treatment

Probiotics can help maintain a healthy gut microbiome or restore populations of “good bacteria” after a heavy course of antibiotics. But now, they could also be used as an effective treatment strategy for certain intestinal diseases, such as Crohn’s disease. Researchers reporting in ACS Central Science have developed a microgel delivery system for probiotics that keeps “good” bacteria safe while actively clearing out “bad” ones. In mice, the system treated intestinal inflammation without side effects.

In the digestive system, there’s a delicate balance of bacterial populations...

AI that uses Sketches to Detect Objects within an Image could Boost Tumor Detection, and Search for Rare Bird Species

Teaching machine learning tools to detect specific objects in a specific image and discount others is a “game-changer” that could lead to advancements in cancer detection, according to leading researchers from the University of Surrey.

Surrey is set to present its unique sketch-based object detection tool at this year’s Computer Vision, Pattern, and Recognition Conference (CVPR). The tool allows the user to sketch an object, which the AI will use as a basis to search within an image to find something that matches the sketch — while discounting more general options.

Professor Yi-Zhe Song, leads this research at the University of Surrey’s Institute for People-Centred AI. He commented:

“An artist’s sketch is full of individual cues that words cannot convey concisely, reiterating...

Low-dose Aspirin may Increase Anaemia Risk in Healthy Older Adults: Study

A new study analysing data from the landmark ASPREE trial has found that prolonged daily aspirin use increases the risk of anaemia by 20 per cent in people mostly aged 70 and over.

The results have prompted researchers to suggest that regular monitoring for anaemia be considered for older adults who take low-dose aspirin, and if older adults have concerns about their health or medications they should discuss them with their GP.

The Monash University-led study, published in Annals of Internal Medicine, followed 18,153 initially healthy older adults in Australia and the USA and recorded incidents of anaemia over an average 4.7 years.

The risk of developing anaemia was found to be 20 per cent higher in the aspirin group compared to those...
