Abstract
Kidneys, like other organs, have an inherent capacity to recover from acute injury; however, severe or
recurrent injury can result in chronic kidney disease (CKD), the sequelae of which result in 82,000 deaths
annually in the US alone. Regardless of the etiology of the initial injury, the common final pathway leading to-
end stage renal disease is closely connected to fibrosis(excess or aberrant collagen distribution), one of the
most important determinants of renal disease severity and prognosis. Histology is the gold standard for
evaluation, typically through the use of histochemical stains such as trichrome and PAS that highlight the
presence of collagens and basement membrane, respectively. Nevertheless, these stains are not completely
specific, can be technically challenging to perform well and reproducibly, and thus contribute to interobserver
variability and a concomitant decrease in diagnostic precision. Moreover, they also require the preparation of
extra slides and additional staining procedures, and thus increase cost and can prolong the diagnostic process.
We propose to optimize, deploy and test a new kind of microscope, DUET (DUal mode Emission and
Transmission microscopy), developed at UC Davis, that will be a low-cost and very rapid solution for detection
and digital characterization of the presence and distribution of collagen and other macromolecules, directly
from standard formalin-fixed, paraffin-embedded hematoxylin and eosin-stained slides. Specifically, we will
finalize the design of the hardware and software components of the instrument itself, validate imaging
performance against standard histology and immunohistochemical stains for collagen and other components,
and with the assistance of scientists at our partnering institutions (John Hopkins University and University of
Buffalo) develop robust tools for analysis and quantitation of fibrosis. DUET instrument hardware will be shared
with JHU to ensure that the methods are technically reproducible across multiple sites.
The application leverages the expertise across three institutions in optics, biomedical engineering, renal
pathology and novel artificial intelligence approaches. The goal of the project is development and validation of
DUET, which promises to be a robust, inexpensive and practical approach for the rapid and accurate
evaluation of fibrosis, extensible to other renal pathologies, and indeed across other organs systems, with
significant positive impact on disease research, clinical practice, and patient outcomes.

摘要
肾脏与其他器官一样,具有从急性损伤中恢复的固有能力;然而,严重或
复发性损伤可导致慢性肾病(CKD),其后遗症导致82,000人死亡
每年仅在美国。不管最初损伤的病因是什么,最终导致-
终末期肾病与纤维化(过量或异常的胶原蛋白分布)密切相关,纤维化是最常见的疾病之一。
肾脏疾病严重程度和预后的最重要决定因素。组织学是金标准,
评估,通常通过使用组织化学染色,如三色和PAS,突出了

具体来说,在技术上很难表现良好和可重复,因此有助于观察者之间的交流。
变异性和伴随的诊断精度降低。此外,它们还需要准备
额外的载玻片和额外的染色程序,从而增加了成本,并可能延长诊断过程。
我们建议优化,部署和测试一种新的显微镜,DUET(双模式发射和

该应用程序利用了光学,生物医学工程,肾脏和肾脏三个机构的专业知识。
病理学和新的人工智能方法。该项目的目标是开发和验证
DUET有望成为一种强大,廉价和实用的方法,用于快速准确地
