Pax6 is a member of the Pax family of transcription factors and is essential for eye development. Pax6 has two DNA-binding domains: the paired domain and the homeodomain. The Pax6 paired domain is involved in Pax6 gene autoregulation by binding to its enhancer. In this study, crystallization and preliminary X-ray diffraction analysis of the mammalian Pax6 paired domain in complex with the Pax6 gene enhancer was attempted. The Pax6 paired domain complexed with an optimized 25 bp DNA fragment was crystallized by the hanging-drop vapour-diffusion method. The crystal diffracted synchrotron radiation to 3.0/3.7 A resolution and belongs to the monoclinic space group P2(1), with unit-cell parameters a = 62.21, b = 70.69, c = 176.03 A, beta = 90.54 degrees. Diffraction data were collected to 3.7 A resolution.

Background: Different domains of cognitive function are important in some jobs, such as office work. Ergonomic risk factors may affect cognitive function.
Aim: This study was designed to assess the effect of an ergonomic training intervention on the cognitive function of office workers.
Traditional numerical reconstruction methods in digital holography (DH) are faced with problems such as inaccurate and time-consuming unwrapping or the need to capture multiple holograms with different diffraction distances. In recent years, deep learning, believed to be a new and effective optimization tool, has been widely used in digital holography. However, most supervised deep learning methods require large-scale paired data, and their preparation is time-consuming and laborious.

Background: CAR T-cell therapy (CAR-T) is leading to durable responses in patients with cancer but there is concern that cytokine release syndrome (CRS) and neurotoxicity may impact survivors' cognitive function. We assessed long-term cognitive function in CAR-T recipients and examine factors associated with change in cognition over time.
Methods: We assessed perceived cognition (Functional Assessment of Cancer Therapy - Cognition) and neurocognitive performance (standardized neuropsychological battery) in adult patients prior to receiving CAR-T and at 6 month follow-up.
