Article Synopsis
- - The study investigates the impact of increased sulfate (SO₄) concentrations in eutrophic lakes, revealing that exogenous sulfur input primarily drives these increases, with notable fluctuations in water and sediment concentrations recorded across multiple lakes and over time.
- - Eutrophication, exacerbated by nutrient input like nitrogen and phosphorus, destabilizes the sulfur cycle, leading to a significant increase in SO concentrations, particularly in sediments, which positively correlate with the trophic lake index (TLI).
- - Experiments indicate that the anaerobic conditions created by cyanobacteria decomposition facilitate sulfate reduction and significantly affect SO levels, highlighting the complex interplay between eutrophication and sulfur dynamics in freshwater ecosystems.
Objective: To investigate the value of the pre-operative amide proton transfer-weighted (APTw) MRI to assess the prognostic factors in rectal adenocarcinoma (RA).
Methods: This prospective study ran from January 2022 to September 2023 and consecutively enrolled participants with RA who underwent pre-operative MRI and radical surgery. The APTw signal intensity (SI) values of RA with various tumor (T), node (N) stages, perineural invasion (PNI), and tumor grade were compared by Mann-Whitney U-test or t-test.
Alternative splicing is a key mechanism that regulates protein diversity and has been found to be associated with colon cancer progression and metastasis. However, the function of alternative splicing in chemoradiation‑resistant colon cancer remains elusive. In this study, we constructed a chemoradiation‑resistant colon cancer cell line.

To date, the imaging features of EWS/PNET have not been clearly described. Here, we report two cases of EWS/PNET confirmed by fine-needle aspiration biopsy and analyze the findings of computed tomography and ultrasound.

Previous attempts to develop the surfactant spermicide, nonoxynol-9 (N-9), into a vaginal microbicide were unsuccessful largely due to its inefficiency to kill microbes. Furthermore, N-9 causes damage to the vaginal epithelium, thus accelerating microbes to enter the women's body.

Methods: Forty rats were divided into three groups: (I) a control group that was submitted to MEMRI or to fluorescent labeling of retinal ganglion cells (RGCs) (n = 10); (II) an ON injury group that was submitted to MEMRI (n = 15); (III) an ON injury group that was submitted to fluorescent labeling of RGCs (n = 15). Groups II and III were examined at 3, 7, and 14 days post-lesion (dpl), when the contrast-to-noise ratio (CNR) of the retina and ON was measured on MEMRI images and the RGCs were counted by fluorescence microscopy and compared between the groups.
