Based on the biologically active heterocycle quinoline, we successfully synthesized a series of quinoline-based dihydrazone derivatives (3a-3d). H NMR, C NMR, ESI-HRMS, IR, element analysis, UV/Vis spectroscopy and fluorescence spectroscopy were performed to comprehensively characterize their chemical structures, spectral properties and stability. Nitrosamine impurities were not detected in 3a-3d, and the systemic toxicological assessment indicated that the toxicity of 3a-3d was lower.

After many years of mining in the Fang2 block of the Songfangtun oilfield, the conventional water drive development method can no longer meet the requirement of greatly improving the recovery rate, and ternary composite drive (TCD) technology is adopted for this purpose. TCD is one of the most important methods to further improve crude oil recovery, and it has entered the industrialization and promotion stage, but there are still problems of fouling in the injection and extraction system and high production and maintenance costs. In order to reduce formation damage and improve recovery in the Songfangtun oilfield, an alkali-free microemulsion system was developed by replacing the weak base sodium carbonate with sodium chloride, but its emulsification capacity was weak and the recovery enhancement value was lower than that of the weak base TCD.

Periodontitis, the chronic inflammation of the periodontal tissues caused by bacteria in plaque, is the leading cause of tooth loss in adults in the world. Currently, periodontitis is effectively treated with mechanical cleaning and the use of antibiotics. However, these treatments only temporarily remove plaque, which can rapidly proliferate and multiply in periodontal pockets over time.

Article Synopsis
  • Leaf dark respiration (R) is crucial for carbon cycling in forests but is often not quantified properly; this study examined how R relates to various leaf traits like maximum carboxylation capacity (V) across different forest types in China.
  • The research found that leaf magnesium and calcium concentrations are more relevant for explaining R variability than more common traits like leaf mass per area (LMA) and nitrogen (N) concentrations, but the relationships are generally weak and specific to each forest type.
  • Leaf spectroscopy proved to be a more effective method for predicting R compared to traditional trait relationships, revealing new traits with broader applicability and suggesting that spectroscopy could enhance models of plant respiration.

  • The study aimed to determine how molecular classification impacts the success of fertility-sparing treatments (FST) in early-stage endometrial cancer (EC) and how this information might optimize patient management.
  • A total of 116 patients with molecularly classified EC were analyzed, showing comparable complete response (CR) rates across different subtypes, though treatment times varied, with POLE EDM patients responding the quickest.
  • The findings suggest that POLE EDM patients may have the best outcomes with FST, while patients with MMR-D require careful monitoring due to the longer time needed for treatment. More research is necessary due to limited sample sizes in some subtypes.
