Ecological distribution of ammonia oxidizers in Yellow River sediments and their influencing factors.

Environ Res

December 2024

Australian Centre for Water and Environmental Biotechnology (ACWEB, Formerly AWMC), The University of Queensland, St. Lucia, Queensland, 4072, Australia.

Ammonia oxidation, the first and rate-limiting step of nitrification, is a crucial step in nitrogen cycling. The distribution patterns of key ammonia oxidizers, including ammonia-oxidizing archaea (AOA) and bacteria (AOB), and comammox (complete ammonia oxidation) Nitrospira, provide vital insights for nitrogen cycling in natural ecosystems. Currently, the distribution and contribution of AOA, AOB and comammox Nitrospira in freshwater ecosystems remain largely underexplored.

In the realm of energy storage, flexible portable supercapacitors have been receiving increasing attention in the last few years. Nonetheless, the process of choosing appropriate flexible materials remains challenging. Herein, we successfully synthesized a flower-like MnCoO@FeCoNi-LDH/CC (MnCo@FCN/CC) hierarchically nanostructured electrode material by anchoring MnCoO (MnCo) on a flexible carbon cloth (CC) substrate first and then loading FeCoNi-LDH nanosheets on MnCoO.

Background: Pulmonary sarcomatoid carcinoma (PSC) is a highly aggressive malignancy with a significant risk of recurrence even after surgical intervention, leading to a dismal prognosis. In recent years, perioperative immunotherapy has demonstrated promising results in resectable non-small cell lung cancer (NSCLC). However, there is a lack of studies reporting the efficacy of perioperative immunotherapy in PSC.

Article Synopsis
  • The study aimed to evaluate various radiomics models for predicting the malignancy potential of small intestinal stromal tumors (SISTs) and identify the most effective model.
  • A total of 140 patients' CT images were analyzed, leading to the extraction of 1132 radiomics features, with different machine learning techniques (like SVM and Random Forest) used to build prediction models.
  • Results indicated that the Support Vector Machine (SVM) model performed best with the highest predictive accuracy (AUC 0.910), while the combined nomogram model slightly outperformed the radiomics model, indicating both approaches are effective in assessing SISTs malignancy.

Background: In recent years, the systemic immune-inflammatory index (SII) and prognostic nutritional index (PNI) have been considered potential predictors of survival outcomes in various solid tumors, including gastric cancer. However, there is a notable lack of research focusing on their prognostic implications specifically in the early stage of gastric cancer. This study aims to investigate the prognostic indicators of early gastric cancer (EGC), including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), SII, PNI, and lymph node metastasis (LNM).
