Studies implicate that gut dysbiosis is related with many neurological diseases. However, the potential role of gut dysbiosis in cryptogenic stroke (CS) has not been elucidated yet. In this study, a high prevalence of gastrointestinal (GI) dysfunction and gut inflammation with increased intestinal permeability have been found in CS patients compared with normal controls (NCs).

- The global dental implant market is projected to grow from $3.7 billion in 2015 to $7 billion by 2023, driven by an annual growth rate of 8.2%.
- Incorporating coatings with antibacterial and osteogenic agents like graphene oxide, lysozyme, and tannic acid can improve the success of dental implants.
- The study demonstrates that a multilayer coating technique enhances both antibacterial properties and the growth of dental pulp stem cells, indicating promising advancements for dental implant surfaces.

Objective: To develop a method for the determination of nicotine and cotinine in urine samples by dispersive liquid-liquid microextraction (DLLME) combined with gas chromatography-mass spectrometry (DLLME-GC/MS).
Methods: The experimental conditions for GC-MS and DLLME were investigated in detail. DLLME was performed with the following procedure: 5 mL of urine sample was adjusted to pH9.
