Article Synopsis
- The study focuses on understanding how the HB virus causes harmful liver inflammation, aiming for early detection and treatment through corticosteroids or chemotherapy.
- The researchers have developed a new mathematical model to analyze the effects of the HB virus, emphasizing stability and reliability through various stability analyses.
- The research also explores control measures for preventing chronic HBV infections, using simulations to assess treatments in asymptomatic individuals within the community.
Radical (R) and R-hole site-based interactions are comparatively studied, for the first time, using methods. In this regard, R-bearing molecules XO (where X = Cl, Br, and I) were subjected to direct interaction with NH within dimeric and trimeric forms in the form of NH···XO/XO···NH and NH···XO···NH complexes, respectively. As confirmed by electrostatic potential analysis, the studied R-bearing molecules XO had the outstanding potentiality to interact as Lewis acid centers via two positive sites dubbed as R and R-hole sites.

Chitosan and its derivatives have been an emerging biomaterial due to their additional antibacterial effect and promising re-mineralizing ability.
Aim: The aim of this study is to evaluate the effect of chitosan nanoparticles on the remineralization of the demineralized enamel surface after being added to nano-hydroxyapatite and nano-calcium phosphate materials.
Article Synopsis
- Fungal diseases significantly impact cantaloupe crops, prompting a search for safer alternatives to hazardous synthetic fungicides, such as using bio agents and natural plant extracts with antibacterial properties.
- A study introduced a new method combining sp. culture filtrates and extracts from specific plants to combat wilt and root rot diseases in infected cantaloupe roots, showing effective antagonistic activity against various fungal isolates.
- Pot experiments revealed that using a combination of sp. culture filtrates and plant extracts significantly protected cantaloupe against diseases, indicating a promising alternative to chemical fungicides.
