The high dynamic range (HDR) CMOS image sensor has been widely used in many fields,such as autonomous driving and security guarding [1].The dual conversion gain (DCG)structure,which adjusts the conversion gain (CG) by changing the capacitors connected to the floating diffusion (FD)nodes in the pixel,is an effective and prevalent method for realizing HDR imaging [2].While the DCG structure can extend the dynamic range,in the practical HDR imaging process,the substantial number of photo-generated electrons in bright areas can cause significant voltage variations in the pixel *** variations affect the gray values in darker areas of the same image,leading to the streak effect [3].This study primarily investigates the streak effect caused by forward conduction current of the PN junction in DCG pixels,and proposes a circuit to suppress this effect.

Detecting and diagnosing neurological diseases in modern healthcare presents substantial challenges that directly impact patient outcomes. The complex nature of these conditions demands precise and quantitative monitoring of disease-associated biomarkers in a continuous, real-time manner. Current chemical sensing strategies exhibit restricted clinical effectiveness due to labor-intensive laboratory analysis prerequisites, dependence on clinician expertise, and prolonged and recurrent interventions. Bio-integrated electronics for chemical sensing is an emerging, multidisciplinary field enabled by rapid advances in electrical engineering, biosensing, materials science, analytical chemistry, and biomedical engineering. This review presents an overview of recent progress in bio-integrated electrochemical sensors, with an emphasis on their relevance to neuroengineering and neuromodulation. It traverses vital neurological biomarkers and explores bio-recognition elements, sensing strategies, transducer designs, and wireless signal transmission methods. The integration of in vivo biochemical sensors is showcased through applications. The review concludes by outlining future trends and advancements in in vivo electrochemical sensing, and highlighting ongoing research and technological innovation, which aims to provide inspiring and practical instructions for future research.

Background : Traditional DNA microinjection methods used in mammals are difficult to apply to avian species due to their unique reproductive characteristics. Genetic manipulation in chickens, particularly involving immature follicles within living ovaries, has not been extensively explored. This study seeks to establish an efficient method for generating transgenic chickens through ovarian injection, potentially bypassing the challenges associated with primordial germ cell (PGC) manipulation and fertilized egg microinjection. Methods : Hens were anesthetized and underwent a surgical procedure to access the ovary for DNA injection into immature follicles. The study used liposomes to deliver GFP- expressing plasmids at various dosages. After injection, hens recovered, and their eggs were fertilized through artificial insemination. Results : Transgenic chickens were successfully generated in one generation without needing G0 founders. The injection of 20 μg plasmid yielded the highest transgenic efficiency at 12.1%. GFP- positive embryos were confirmed through microscopy, and successful transgene expression was validated at the tissue level using immunostaining. TERT and GFP elements introduced in the G1 generation resulted in 4.1% positive transgene rates, as confirmed by PCR and Southern blotting. Conclusion : This ovarian injection method offers a promising alternative for avian genetic manipulation, bypassing complex PGC procedures and enabling direct generation of G1 transgenic chickens. This technique simplifies the transgenic process for chickens and has the potential to be adapted for other avian species, especially those without established PGCs culture systems.
