Rheumatoid arthritis (RA) is an autoimmune disease characterized by bone and joint degeneration. Existing anti-inflammatory chemotherapy drugs offer temporary relief but come with undesirable side effects. Herbal medications have shown positive effects on RA symptoms with minimal adverse reactions. In this study, we investigated the potential of Nyctanthes arbor-tristis (NAT) through in vitro and in silico research. Hydroethanolic extracts of harsingar were prepared using the reflux method, containing alkaloids, phenol, saponin, steroids, proteins, tannins, terpenoids, carbohydrates, glycosides, and flavonoids, which exhibited TPC (98.56 ± 0.46 mg GAE/g) and TFC (34.51 ± 0.45 mg CE/g). LC–MS/MS analyzes the active compounds in the extract. NAT exhibited the best scavenging capabilities at 1 mg/mL in anti-oxidant and anti-arthritic activity. Maximum splenocyte proliferation occurred at 250 µg/mL. In vitro cell splenocyte studies revealed the downregulation of TNF-α and the upregulation of IL-10. Additionally, an in silico study demonstrated that bioactive constituents and targets bind with favorable binding affinity. These findings demonstrate the potential of Nyctanthes arbor-tristis in exerting anti-arthritic effects, as supported by in vitro and in silico studies. Further mechanistic research is necessary to validate the therapeutic potential of all phytoconstituents in RA treatment.

Background: Gout is a chronic inflammatory condition characterized by elevated uric acid levels in the blood, which can precipitate acute gout attacks in individuals with genetic susceptibility, existing medical conditions, and dietary influences. Genetic predispositions, comorbid medical conditions, nutritional choices, and environmental factors increasingly recognize the multifactorial etiology of the disease. Methods: Recent research has highlighted the potential of phytochemicals, particularly flavonoids, saponins, and alkaloids, to manage hyperuricemia (HUA) and its associated complications. Results: Plant’s natural compounds have garnered attention for their anti-inflammatory, antioxidant, and uric acid-lowering properties, suggesting their role in alternative and complementary medicine. Phytochemicals have demonstrated promise in mitigating gout symptoms and potentially modifying the disease course by addressing different aspects of hyperuricemia and inflammation. Herbal remedies, with their complex phytochemical profiles, offer a unique advantage by potentially complementing conventional pharmacological treatments. The integration of herbal therapies with standard medications could lead to enhanced therapeutic outcomes through synergistic effects, optimizing disease management, and improving patient quality of life. Conclusions: This review examines the current understanding of the multifaceted etiology of gout, explores the role of phytochemicals in managing hyperuricemia, and discusses the potential benefits of combining herbal remedies with conventional treatments to improve patient care and therapeutic efficacy.

The nanoparticle is one of the most intensively studied areas in science ranging from engineering to medical fields and has been a center of attraction that is explored to find new and promising dimensions for its use. These nanoparticles have obtained eminence because of their potential efficacy, shape, and size. In the field of nanoscience, the use of natural resources is an emerging topic of interest that has been taken into consideration due to the presence of a reservoir of a priceless wellspring of novel and new chemical entities that have a therapeutic effect. The system has found its space in the treatment of many diseases, including Diabetes, Neurological disorders, Cardiovascular Disorders, and even cancer. At present, cancer is one of the most common causes of death all over the world. Various drugs are used to treat numerous types of cancers, but at the same time, they are found to be harmful to the patient and produce several side effects. To meet the gap, herbal nanoparticles have been studied and are found to be non-hazardous and environmentally friendly. Herbal nanoparticles are synthesized to target various biological pathways that induce cancer and pieces of evidence have shown comparable efficacy like other drugs that have been used conventionally for cancer treatment. The review highlights the mechanism of action and prospects of the nanotechnological approach using phytochemicals for the treatment of cancer and will help to bridge the gap between herbal nanotechnology and current knowledge related to it.

Biological wastewater treatment is a frontier research area considering the welfare of the living population. Treatment systems are economical, efficient, and effective in reducing the organic load of wastewater. Also, they facilitate the recovery of heavy metals, upgraded plant nutrients, bio-energy resources, and several biosolids by bacteria, algae, or fungi. Microbes in pure cultures, as well as in consortium efficiently work toward clearing industrial effluents, converting them into nontoxic or minimally toxic materials. This chapter presents insights into aerobic, anaerobic, and anoxic biological wastewater treatment bioreactors, with due focus on the underlying bioprocesses. Respective advantages and drawbacks are elucidated from an industrial point of view. Advancements in waste utilization, such as recovery of energy resources and nutrients from wastewater, have also been scrutinized. The details provided are of huge significance to industrial facilities, and help in minimizing anthropogenic environmental deterioration. The prime objective of this chapter is to provide a concise content, along with quick reference for environmental researchers, engineers, and industrialists for combating environmental pollution.
