The release of the first draft of the human pangenome has revolutionized genomic research by enabling access to complex regions like centromeres, composed of extra-long tandem repeats (ETRs). However, a significant gap remains as current methodologies are inadequate for producing sequence alignments that effectively capture genetic events within ETRs, highlighting a pressing need for improved alignment tools. Inspired by UniAligner, we develope Rare Match Aligner (RaMA), using rare matches as anchors and 2-piece affine gap cost to generate complete pairwise alignment that better capture genetic evolution.

To address this issue, researchers have designed MSA methods rooted in a vertical division strategy, which segments sequence data for parallel alignment.

Thirty-five patients with SBO and who had neither strangulation nor other contradictions received intestinal decompression, under the guidance of X-ray, using a 300-cm-long nasointestinal tube which reached the upper jejunum. Contrast radiography of intestines was performed when the tip of the decompression tube reached the obstruction by administering double-contrast medium, containing 20-100 ml 76 % gastrografin and 50-200 ml air, through the nasointestinal tube.
