Article Abstract
The global spread of infectious diseases has raised public awareness of vaccines, highlighting their essential role in protecting public health. Among the components of modern vaccines, adjuvants have received increasing attention for boosting immune responses and enhancing efficacy. Recent advancements in adjuvant research, particularly nanodelivery systems, have paved the way for developing more effective and safer adjuvants. This review outlines the properties, progress, and mechanisms of FDA-approved conventional adjuvants, focusing on their contributions to and challenges in vaccine success. Despite these advancements, conventional adjuvants still face suboptimal immunomodulatory effects, potential side effects, and limitations in targeting specific immune pathways. Nanodelivery systems have emerged as a transformative approach in adjuvant design, offering unique advantages such as enhancing vaccine stability, enabling controlled antigen release, and inducing specific immune responses. By addressing these limitations, nanocarriers improve the safety and efficacy of conventional adjuvants and drive the development of next-generation adjuvants for complex diseases. This review also explores strategies for incorporating nanodelivery systems into adjuvant development, emphasizing its role in optimizing vaccine formulations. By summarizing current challenges and recent advances, this review aims to provide valuable insights guiding future efforts in designing innovative adjuvants that meet the evolving needs of global immunization programs.

Anaerobic bacteria cause a wide range of infections, varying from mild to severe, whether localized, implant-associated, or invasive, often leading to high morbidity and mortality. These infections are challenging to manage due to antimicrobial resistance against common antibiotics such as carbapenems and nitroimidazoles. The empirical use of antibiotics has contributed to the emergence of resistant organisms, making the identification and development of new antibiotics increasingly difficult.

Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by joint inflammation. Given the side effects of conventional treatments, this study focuses on the anti-inflammatory effects of purslane (Portulaca oleracea) and turmeric (Curcuma longa). The research is driven by the growing demand for plant based-treatment for safer therapeutic options for RA management.

Surgical resection remains the frontline intervention for cancer; however, postoperative tumor recurrence and wound infection remain critical unmet challenge in surgical oncology. Herein, an all-in-one nanowired hydrogel (V-Hydrogel) is developed through a facile one-step assembly employing enzyme-mimetic VO nanowires and bactericidal crosslinker THPS. The V-Hydrogel reserves the glutathione peroxidase-, peroxidase-, catalase-, and oxidase-mimetic enzymatic activities derived from vanadium oxide nanowires, thereby exhibiting efficient tumor-specific catalytic therapy.

Among the various types of tumors, breast cancer (BC) has a high distribution in the world population and is responsible for a high mortality rate. Like other forms of cancer, BC is characterised by distinctive features such as high-energy metabolism in tumor cells, genetic mutations, and mitochondrial dysfunction that sometimes make conventional therapies less effective. However, there is a growing awareness of the vital role played by diet therapy in the overall management of the patient with BC, both by supporting standard therapy and by directly targeting aberrant biological processes involved in carcinogenesis.
