The balance of mental, physical, and technical aspects is essential in improving ballet performance. Ballet dancers' emotional and behavioral characteristics vary, even under identical stress conditions. This study aimed to investigate the association between the pain candidate genes 5-HTTLPR and COMT and anxiety in Japanese ballet dancers.

Article Synopsis
- Ptychography is a computational imaging technique that provides detailed microscopic images, relying on phase-retrieval algorithms for quality results.
- Recent advancements have integrated deep neural networks (DNN) into phase retrieval processes to enhance imaging quality, although challenges arise from these methods being sensitive to experimental changes and the need for extensive image datasets for training.
- A novel approach combines DNN and model-based algorithms, using a DNN denoiser with synthetic training data, which allows for improved image reconstruction with fewer iterations and greater adaptability to varying conditions, as validated by experimental results.
Aim: This study aimed to investigate the effectiveness of a modified incision line on the lesser curvature for gastric conduit formation during esophagectomy in enhancing the perfusion of gastric conduit as determined by indocyanine green fluorescence imaging and reducing the incidence of anastomotic leakage.
Methods: A total of 272 patients who underwent esophagectomy at our institute between 2014 and 2022 were enrolled in this study. These patients were divided based on two different types of cutlines on the lesser curvature: conventional group (n = 141) following the traditional cutline and modified group (n = 131) adopting a modified cutline.
Subgradient-projection-based stable phase-retrieval algorithm for X-ray ptychography.

X-ray ptychography is a lensless imaging technique that visualizes the nano-structure of a thick specimen which cannot be observed with an electron microscope. It reconstructs a complex-valued refractive index of the specimen from observed diffraction patterns. This reconstruction problem is called phase retrieval (PR).

Methods: A total of 425 patients who underwent gastrectomy for primary gastric cancer in our institution between April 2013 and March 2020 were classified by age into two groups: elderly patients (EP, age ≥ 80 years, n = 89); and younger patients (YP, age < 80 years, n = 336). The preoperative, intraoperative, and postoperative conditions of the two groups were then compared.
