Artificial intelligence digitally stains tissue samples used in pathology, saving labor, time and cost

Artificial intelligence digitally stains tissue samples used in pathology, saving labor, time and cost: Histopathology is one of the main methods used for diagnosis of disease. Following a medical screening process, a patient can undergo a biopsy, in which a piece of tissue is removed for further inspection and diagnostic analysis. This tissue specimen is then sliced into thin sections that are on the order of a few millionths of a meter in thickness. These thin sections of tissue contain at the microscopic scale the diagnostic information regarding the patient's condition. However, they exhibit almost no contrast under standard light microscopy. To reveal these microscopic features embedded inside tissue and bring visible contrast for inspection by a pathologist, various tissue staining methods have been created in pathology dating back to more than 150 years ago. These tissue staining procedures use different types of colored dyes that specifically label micro-scale structures in tissue, forming colorful images of specimens, which have been widely used as a gold standard diagnostic method in modern medicine.

It’s a Dog-Eat-Dog World

It’s a Dog-Eat-Dog World: We can all unhappily discuss the harm that such groups can do to academic communities, and what each of us can do to avoid falling prey to them. But we must ask ourselves: are these predators the problem – or are they a symptom? If our academic communities have built an environment where such publications and conferences can flourish, is there something fundamental that must change? And if so… where do we begin?
