Environmental pollution of heavy metals is increasingly becoming a problem and has become of great concern due to the adverse effects it is causing around the world. These inorganic pollutants are being discarded in our waters, soils and into the atmosphere due to the rapidly growing agriculture and metal industries, improper waste disposal, fertilizers and pesticides. This review shows how pollutants enter the environment together with their fate. Some metals affect biological functions and growth, while other metals accumulate in one or more different organs causing many serious diseases such as cancer. The pharmacokinetics and toxicological processes in humans for each metal is described. In summary, the review shows the physiological and biochemical effects of each heavy metal bioaccumulation in humans and the level of gravity and disquieting factor of the disease.

Though honey has long been used as medicine, there is a scarcity of knowledge on how it interacts with the body. While different types of honey have different chemical and medicinal properties according to their origin, this narrative review seeks to analyse the current knowledge on the chemical composition and therapeutic use of honey. With numerous chemical components, honey has a range of health benefits in multiple disciplines of medicine, and provides an interesting prospect in chemical analysis with regards to identification of its origin. There is a great potential for the use of honey in medicine, primarily due to its antioxidant and antimicrobial properties. Recent studies on the phenolic and enzymatic components of honey have made honey's therapeutic method of action in relation to the above properties clearer, still more research needs to be conducted and more innovations need to be tested, for the full potential of honey to be understood.

Mycelium-based composites hold significant potential as sustainable alternatives to traditional materials, offering innovative solutions to the escalating challenges of global warming and climate change. This review examines their production techniques, advantages, and limitations, emphasizing their role in addressing pressing environmental and economic concerns. Current applications span various industries, including manufacturing and biomedical fields, where mycelium-based composites demonstrate the capacity to mitigate environmental impact and enhance economic sustainability. Key findings highlight their environmental benefits, economic viability, and versatile applications, showcasing their potential to revolutionize multiple sectors. However, challenges such as consumer acceptance, intrinsic variability, and the need for standardized guidelines persist, underscoring the importance of further research and innovation. By optimizing material properties and refining production processes, mycelium-based composites could pave the way for widespread adoption as sustainable materials, contributing to a greener and more environmentally conscious future.

Throughout this review, the underlying physiological mechanisms attributed to these properties by its phytochemicals are explored. Concurrently, the review addresses its pharmacological safety, ensuring a nuanced understanding of its applications in medicinal industries. In summary, this literature review presents a comprehensive exploration of Moringa oleifera, focusing on its phytochemical composition, health benefits, physiological mechanisms, pharmacological safety and nutritional importance.

Neurodegeneration is a multifactorial process involved the different cytotoxic pathways that lead to neuronal cell death. Alzheimer’s disease (AD) is a persistent neurodegenerative disorder that normally has a steady onset and gradually worsens. Neuropathology, AD is characterized by the presence of neuroinflammation, mitochondrial dysfunction, increased oxidative stress, decreased antioxidant defense as well as increased acetylcholinesterase activity. Moreover, enhanced expression of amyloid precursor proteins leads to neural apoptosis, which has a vital role in the degeneration of neurons. The inability of commercial therapeutics to treat a single feature of AD pathology leads to the attraction towards organic drugs. Ellagic acid is a dimer of gallic acid; latest studies revealed that ellagic acid can initiate numerous cell signaling transmissions and decrease the progression of neurodegeneration. The neuroprotective effects of ellagic acid to protect the neurons against neurodegenerative events are due to its antioxidant effect, iron chelating, and mitochondrial protective effect. The main goal of this review is to critically analyze the molecular mechanism of action of ellagic acid against AD.

The outbreak of monkeypox virus (MPXV) was declared a Public Health Emergency of International Concern (PHEIC) by the World Health Organization (WHO), and the zoonotic disease caused by viral infection was renamed as “Mpox” on November 28, 2022. Currently, there is no approved vaccine or specific antiviral treatment for Mpox, and a main preventive strategy against MPXV infection remains the smallpox vaccine. Although there was an emergency use authorization (EUA) of Brincidofovir and Tecovirimat for the clinical treatment of clade II Mpox, while Tecovirimat failed to reduce the duration of Mpox lesions among patients infected with clade I Mpox in the Democratic Republic of the Congo (DRC). Therefore, it is still an urgent need to develop an effective medication. This review aims to enhance the understanding of Mpox and contribute to its prevention and treatment strategies, it provides a systemic introduction of the biological and epidemiological characteristics of MPXV, the clinical feature and diagnosis of Mpox, as well as treatment and prevention strategies, which will improve the comprehension about MPXV and offer potential strategies for clinical treatment.
