Intrinsic tooth discoloration may occur as an adverse effect of fluoride and tetracyclines. Extrinsic tooth discoloration may occur as superficial staining or as discoloration of the superficial pellicle and/or biofilm due to chlorhexidine, liquid iron salts, essential oils, some antibiotics and stannous fluoride. Inhibition of orthodontic tooth movement has been reported due to the use of prostaglandin synthetase inhibitors. If medications or over-the-counter drugs induce hyposalivation or contain much sucrose, caries may develop...

Tumor-associated macrophages (TAMs) play a key role in all stages of tumorigenesis and tumor progression. TAMs secrete different kinds of cytokines, chemokines, and enzymes to affect the progression, metastasis, and resistance to therapy depending on their state of reprogramming. Therapeutic benefit in targeting TAMs suggests that macrophages are attractive targets for cancer treatment. Chinese materia medica (CMM) is an important approach for treating cancer in China and in the Asian region. According to the theory of Chinese medicine (CM) and its practice, some prescriptions of CM regulate the body's internal environment possibly including the remodeling the tumor microenvironment (TME)...

Aconiti Lateralis Radix Praeparata (Fuzi), a type of Chinese materia medica, has been used to treat acute and chronic heart failure (HF) in traditional Chinese medicine and has been proven in numerous animal studies. It is also well-known that Zingiberis Rhizoma (Ganjiang) is ineffective in the treatment of HF, but it can enhance the anti-HF effect of Fuzi. However, the mechanism underlying this compatibility is still not well investigated. To investigate this mechanism, a model of acute heart failure (AHF) in SD rats induced by propafenone hydrochloride was established in this study...
