Rivers link land and sea, playing an important role in the global carbon and nitrogen cycles. By conducting surveys and research on river flow in a specific region, we can gain a better understanding of the nitrogen and carbon sinks in the area and their contributions to the environment. In this study, we conducted bi-annual sampling and monitoring of river flow in the Pearl River Delta downstream of Zhuhai, China, and collected hydrological information.

Wild birds are important hosts of influenza A viruses (IAVs) and play an important role in their ecology. The emergence of the A/goose/Guangdong/1/1996 H5N1 (Gs/GD) lineage marked a shift in IAV ecology, leading to recurrent outbreaks and mortality in wild birds from 2002 onwards. This lineage has evolved and diversified over time, with a recent important derivative being the 2.

Bladder cancer is categorized into nonmuscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC), distinguished by the presence of detrusor muscle invasion. Urothelial cell carcinoma is the most common subtype of bladder cancer. Transurethral resection of bladder tumor (TURBT) is the standard approach for staging and managing NMIBC, while radical cystectomy remains the cornerstone treatment for MIBC.

Article Synopsis
- In drug-resistant epilepsy, the study focuses on using deep learning to analyze intracranial electroencephalography (iEEG) signals, specifically through time-frequency (TF) images, to locate the epileptogenic zone (EZ) for surgical guidance.
- The researchers processed iEEG data from 20 children and employed a pre-trained neural network (VGG16) to measure visual complexity, revealing that contacts within the seizure onset zone had significantly lower activation energy compared to those outside.
- The findings suggest a new computer-assisted method for accurately localizing the EZ with a 7 mm accuracy in MRI scans, potentially reducing the need for extensive manual iEEG examinations.
Integrating Payor-Segregated Outpatient Obstetrics and Gynecology Care Models: The Patient Perspective.

Objective: Significant racial and ethnic disparities in maternal morbidity and mortality as well as gynecologic outcomes persist in the United States. The role of ambulatory care in obstetrics and gynecology (OBGYN), particularly in facilities that separate resident and attending care along payor (and de facto racial) lines, remains unclear. This study examines patient perspectives on payor-segregated health care delivery in an academic medical center (AMC) and opinions on possible integration.
