Usefulness of four-dimensional noise reduction filtering using a similarity algorithm in low-dose dynamic computed tomography for the evaluation of breast cancer: a preliminary study.

Purpose: To evaluate the effects of four-dimensional noise reduction filtering using a similarity algorithm (4D-SF) on the image quality and tumor visibility of low-dose dynamic computed tomography (CT) in evaluating breast cancer.

Materials And Methods: Thirty-four patients with 38 lesions who underwent low-dose dynamic breast CT and were pathologically diagnosed with breast cancer were enrolled. Dynamic CT images were reconstructed using iterative reconstruction alone or in combination with 4D-SF.

Urodele amphibian newt bridges the missing link in evo-devo of the pancreas.

Background: The pancreas exhibits diverse structures and roles across vertebrates. The pancreas has evolved to include both endocrine and exocrine cells, a change that occurred during the transition from fish to amphibian. This event emphasizes the evolutionary significance of amphibians.

Novel function of Hox13 in regulating outgrowth of the newt hindlimb bud through interaction with Fgf10 and Tbx4.

5'Hox genes regulate pattern formation along the axes of the limb. Previously, we showed that Hoxa13/Hoxd13 double-mutant newts lacked all digits of the forelimbs during development and regeneration, showing that newt Hox13 is necessary for digit formation in development and regeneration. In addition, we found another unique phenotype.

Secondary Revision after Breast Reconstruction with Free Abdominal Perforator Flap: Flap Liposuction and Inframammary Fold Reconstruction.

Background: In breast reconstruction using the abdominal perforator flap, if the flap capacity is too large, secondary revision procedures can be performed to reduce flap volume and reconstruct the inframammary fold (IMF). We examined the various revision methods and cosmetic results.

Methods: This study included 28 patients who underwent secondary revision among 216 patients who had breast reconstruction using the abdominal perforator flap between April 2012 and March 2019.
