Post-surgical pain affects millions of people every year, and managing it is a critical aspect of patient care (Tait et al., 2018). Effective pain relief is essential both for comfort and also for preventing complications such as chronic pain or delayed recovery. Traditionally, a broad group of pain-relieving medicines known as opioids have been the cornerstone of post-surgical pain treatment. By binding to pain receptors, opioids reduce pain intensity.

2. Results and Discussion 2.1. Yield and Content of Fulvic Acid from Different Types of Peat Figure 1 shows the yields and contents of fulvic acid in herbaceous, woody, and mossy peats. The yield of fulvic acid extracted from herbaceous peat was the highest (2.53%), and the yield of fulvic acid extracted from woody peat was the lowest (0.74%). These results indicate that different types of peat have a significant effect on the fulvic acid yield.

Abstract : Heavy metal pollution caused by industrial wastewater such as mining and metallurgical wastewater is a major global concern. Therefore, this study used modified lignite as a low-cost adsorbent for heavy metal ions. Pingzhuang lignite was dissolved and modified using Fusarium lignite B3 to prepare a biotransformed-lignite adsorbent (BLA). The O, H, and N contents of the BLA increased after transformation, and the specific surface area increased from 1.81 to 5.66 m2·g−1.
