Summary: This paper proposes a design approach using mixed metal-organic frameworks (MOFs) as tunable stationary phases in liquid chromatography (LC). By systematically designing ligands, the pore sizes in the MOFs can be tuned. Columns packed with the MOFs and their mixed-particle/solid-solution stationary phases are prepared and tested for the retention capability of polyethylene glycol (PEG) in LC. The results demonstrate that mixed-linker solid-solution MOFs have higher retention capability compared to pure MOF stationary phases, due to their specific nanostructures.

Summary: Green chromatography techniques using low-toxic mobile phase and developing stationary phases with adequate retention and separation under high content water mobile phase have gained increasing attention. In this study, an undecylenic acid-bonded silica stationary phase (UAS) was successfully prepared using thiol-ene click chemistry. The synthesized UAS demonstrated excellent separation ability towards highly polar compounds under the mobile phase of high content water, surpassing commercial C18 and silica stationary phases. Overall, this UAS stationary phase meets the requirements of green chromatography and shows promise for enhanced separation.

Summary: A new strategy using non-porous silica (NPS) spheres as support and covalent organic frameworks (COFs) as porous functional shell was developed for liquid chromatography, ensuring the independent effect of COFs on separation. NPS@TPB-DMTP was prepared as proof of concept using 1,3,5-tris(4-aminophenyl)benzene (TPB) and 2,5-dimethoxy-1,4-benzenedicarboxaldehyde (DMTP) as monomers by in situ polymerization on the surface of NPS. This new approach of developing COF-based stationary phases will aid in understanding the impact of COFs on separation.

Summary: The G-protein coupled receptor 39 (GPR39) is a potential target for future drugs, and its pharmacology is not fully understood. Zinc acts as an endogenous agonist or an allosteric modulator for GPR39, while TC-G 1008 is a synthetic agonist. Zinc also enhances the activity of TC-G 1008 at GPR39. Activation of GPR39 by TC-G 1008 promotes epileptogenesis in an epilepsy model and decreases seizure threshold in a seizure test. The amount of zinc in the diet contributes to the effects of TC-G 1008 in vivo.

Summary: Bioavailability refers to the fraction of a substance that is absorbed from the gastrointestinal tract and enters the bloodstream. This study aimed to assess the bioavailability of selenium (Se) from dietary supplements and explore the influence of diet type on relative bioavailability. The research used a two-stage in vitro digestion model to simulate the digestion of food containing dietary supplements. Selenium bioavailability ranged from 19.31% to 66.10% in the presence of food matrix. Sodium selenate had the highest bioavailability, followed by organic forms and sodium selenite. The basic diet with moderate protein and high carbohydrate and fiber content positively influenced Se bioavailability. The pharmaceutical form of the product also affected bioavailability, with tablets having the highest bioavailability, followed by capsules and coated tablets.

Summary: Chronic venous disease (CVD) affects up to 30% of the global population and is characterized by disturbances in the microcirculation of veins. Diosmin, a phlebotropic drug, has been used in the treatment of CVD, but its molecular mechanism of action is not fully understood. In this study, patients were administered diosmin and biochemical assays were used to evaluate its effects on oxygen management, angiogenesis, and inflammation. The findings suggest that diosmin may regulate angiogenesis, inflammation, and hypoxia-inducible factor pathway in CVD.

Summary: This review provides an overview of the commonly used clinical methods for treating articular cartilage defects, with a specific emphasis on recent clinical trials. Currently, no single method fully satisfies the requirements for effective cartilage healing while remaining easily applicable during surgical procedures. However, there are several available options and the choice of treatment should take into consideration factors such as the location and size of the cartilage lesion, patient preferences, and whether it is chondral or osteochondral in nature. Promising future directions include tissue engineering, stem cell therapies, and the development of pre-formed scaffolds from hyaline cartilage, offering hope for improved outcomes.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
