Introduction: With the advancement of joint replacements such as total hip replacement (THR), Titanium (Ti) and its alloys are widely used as implant materials. The bearing surface of Ti improves the longevity of implants. In this perception, researchers design a Ti-alloy that increases the wear and corrosion resistance to enhance osteogenesis and mechanical stability.
Areas Covered: : This paper is dedicated to finding the major causes of the failure of THR. Further, this paper provides an overview of the application of metallic alloys and their influencing factors that influence biocompatibility. The most contributing part of this paper focuses on the post-treatment impact on Ti-alloys biocompatibility.
Expert Opinion: This paper revealed and discussed that Ti alloys' biocompatibility for orthopedic applications mainly depends on antibacterial activities that decide tissue-implant compatibility. Therefore, performing surface treatment enhances the biocompatibility of Ti alloys. It was also observed that more water contact angle (WCA) induces bacterial growth and enhances cell adhesion. In contrast, the treated surface increases the antibacterial activities at lower WCA. Surface heat treatment with sintering or micro-arc oxidation achieves suitable antibacterial or antimicrobial activities.

Article Synopsis
- Predicting how well ligands bind to nucleic acids is challenging, which limits the development of small-molecule drugs for diseases like cancer and infections.
- Recent advancements in computational methods, particularly free-energy perturbation (FEP), have improved predictions for protein-ligand binding affinities, but its effectiveness for nucleic acids was unclear.
- This study found that using FEP+ software with the OPLS4 force field can accurately predict binding energies for over 100 ligands interacting with DNA/RNA, achieving predictions that closely match experimental data and could aid drug discovery.

Background: Pseudomonas aeruginosa's inherent and adapted resistance makes this pathogen a serious problem for antimicrobial treatments. Furthermore, its biofilm formation ability is the most critical armor against antimicrobial therapy, and the virulence factors, on the other hand, contribute to fatal infection and other recalcitrant phenotypic characteristics. These capabilities are harmonized through cell-cell communication called Quorum Sensing (QS), which results in gene expression regulation via three major interconnected circuits: las, rhl, and pqs system.

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the leading causes of infection worldwide due to its antimicrobial resistance. Plant-derived essential oils (EOs) have undergone extensive observational and clinical research to explore their antimicrobial properties. The present study aimed to check mec A positive MRSA isolates using sequencing analysis, determination of chemical composition using gas chromatography-mass spectroscopy (GC-MS), antioxidant, and antimicrobial activity of Anethum graveolens and Piper betle EOs against the infectious agent MRSA.

Carbapenems are a class of β-lactam antibacterial drugs with a broad antibacterial spectrum and strong activity, commonly used to treat serious bacterial infections. However, improper or excessive use of carbapenems can lead to increased bacterial resistance, which is a significant concern as they are often used as last resort for treating multidrug-resistant (MDR) gram-negative bacteria. Confronted with this challenge, it is crucial to comprehensively understand the mechanism of carbapenem resistance to develop effective therapeutic strategies and innovative drugs.
