Comparative phenotypic and proteomic analysis of colistin-exposed .

Introduction: The emergence of colistin resistance threatens the treatment of infections.

Methods: In this study, in vitro development of colistin resistance was investigated using comparative phenotypic and proteomic analysis of ATCC 9027, its 14-day colistin sub-MIC exposed strain (Col-E1), and 10-day antibiotic-free cultured Col-E1 strain (Col-E2). Antibiotic susceptibility, morphology, virulence factors, and proteomic changes were assessed using disc-diffusion, agar-based, spectrophotometry, SEM, and iTRAQ-LC-MS/MS methods.

Biosensors for Seafood Safety Control-A Review.

The increased demand for consuming seafood has made seafood production undergo a rapid period of growth. However, seafood has a high risk of contamination from harmful microorganisms and marine toxins which can cause health problems for humans consuming it. Concerning this issue, monitoring seafood safety has become a center of attention for researchers, and developing effective methods for detecting contamination in seafood has become a critical research field.

5-Substituted Flavones-Another Class of Potent Triplex DNA-Specific Ligands as Antigene Enhancers.

In the field of drug development, the quest for novel compounds that bind to DNA with high affinity and specificity never ends. In the present work, we report the newest development in this field, namely, triplex DNA-specific binding ligands based on the 5-substituted flavone scaffold in our lab. Biophysical studies showed that the newly synthesized flavone derivatives (depending on the side chains) bind to triplex DNA with binding affinities better than or similar to 5-substituted 3,3',4',7-tetramethoxyflavonoids.

New Hydrogenated Phenanthrene Glycosides from the Edible Vegetable W.T.Wang with DPP-IV Inhibitory and Hepatoprotective Activity.

Based on molecular networking-guided isolation, 15 previously undescribed hydrogenated phenanthrene glycosides, including eight hexahydro-phenanthrenone glycosides, four tetrahydro-phenanthrenone glycosides, one dihydro-phenanthrenol glycoside, two dimers, and two known dihydrophenanthrene glycosides, were isolated from W.T.Wang, a popular regional edible vegetable at the northwest region of Vietnam.

Fabricating ZnO@C composites based on shell-derived cellulose for high performance lithium-ion battery anodes.

In this study, shell-derived cellulose was successfully produced, and the hydrothermal method was employed to generate ZnO@C (ZOC) composites, which were then subjected to calcination in N gas at a temperature of 600 °C for varying durations. X-ray diffraction and thermogravimetric analyses demonstrated that the annealing duration had a substantial impact on the quantities of C and ZnO in the ZOC composites. The scanning electron microscope images indicated the presence of ZnO nanoparticles on the surface of the C phase and revealed a similar morphology among the ZOC composites.
