Light-modulated neural control of sphincter regulation in the evolution of through-gut.

The development of a continuous digestive tract, or through-gut, represents a key milestone in bilaterian evolution. However, the regulatory mechanisms in ancient bilaterians (urbilaterians) are not well understood. Our study, using larval sea urchins as a model, reveals a sophisticated system that prevents the simultaneous opening of the pylorus and anus, entry and exit points of the gut.

Effects of Drought Stress on Abscisic Acid Content and Its Related Transcripts in - Monosomic Addition Lines.

Climate change has resulted in an increased demand for Japanese bunching onions L., genomes FF) with drought resistance. A complete set of alien monosomic addition lines of with extra chromosomes from shallot ( L.

Assembly of continuous high-resolution draft genome sequence of Hemicentrotus pulcherrimus using long-read sequencing.

The update of the draft genome assembly of sea urchin, Hemicentrotus pulcherrimus, which is widely studied in East Asia as a model organism of early development, was performed using Oxford nanopore long-read sequencing. The updated assembly provided ~600-Mb genome sequences divided into 2,163 contigs with N50 = 516 kb. BUSCO completeness score and transcriptome model mapping ratio (TMMR) of the present assembly were obtained as 96.

Clinical Results of a Trifocal Toric Intraocular Lens Using the Holladay Total Surgically Induced Astigmatism Formula for Correcting Low Corneal Astigmatism in Japanese Patients.

Purpose: To evaluate the effectiveness and safety of the AcrySof IQ PanOptix toric intraocular lens (IOL) with cylinder power of 1.0 D (TFNT20) in a Japanese population with low corneal astigmatism and compare with historical control data for nontoric IOLs.
