Researchers report the use of Linked Color Imaging, an innovative modality that specifically combines selected wavelengths of light for illumination in upper gastrointestinal endoscopy. This method, by enhancing the subtle variations in red and white hues that indicate mucosal transformation, greatly improves the early detection of upper gastrointestinal tract neoplasms as compared with conventional white light illumination.

Researchers have devised a molecular structural modification that boosts the efficacy of antisense oligonucleotide-based drugs by replacing the RNA strand of a heteroduplex oligonucleotide with DNA. This advance expands the scope and clinical applicability of nucleic-acid therapeutics across an ever-widening swathe of intractable diseases including neurological disorders.

A joint research team has developed a deep neural network named DeepTFactor that predicts transcription factors from protein sequences. DeepTFactor will serve as a useful tool for understanding the regulatory systems of organisms, accelerating the use of deep learning for solving biological problems.

Researchers have been trying to figure out what regulates molecular circadian clocks, in search of new insights into diseases like Alzheimer's, cancer and diabetes. Until now, that research has focused on what is known as clock genes. But new research reveals the discovery of a new cog in the circadian clock - a genome-wide regulatory layer made up of small chains of non-coding nucleotides known as micro RNAS (miRNAs).

A research study has found that in pregnancy, while the T cell response to a fetus becomes tolerant to allow for successful pregnancy, the part of the immune system that produces antibodies (known as the humoral response) becomes sensitized, creating memory B cells that can later contribute to the rejection of a transplanted organ.
