Nanotechnology has the potential to offer elegant solutions to problems experienced in the medical field, such as poor drug delivery efficiency and microbial resistance. In this sense, it is interesting to associate nanomaterials with substances that also offer desirable properties to favor human health. Green propolis is an example of a material that contains some of these useful substances. The phenolic acids present in this type of propolis have already been proven to present, for example, antimicrobial, immunostimulant, and antioxidant activities. In this minireview, recent nano solutions based on green propolis, presented through manuscripts recently published, receive attention due to their useful properties in the medical field. Limitations to the clinical use of nanomaterials and the future prospects are also addressed.

Neurological disorders are devastating conditions affecting both cognitive and motor-related functions in aged people. Yet there is no proper medication to treat these illnesses, and the currently available medications can only provide symptomatic relief to the patients. All neurological disorders share the same etiology, such as oxidative stress, mitochondrial dysfunction, neurochemical deficiency, neuronal loss, apoptosis, endoplasmic reticulum stress, neuroinflammation, and disease-related protein aggregation. Nowadays, researchers use antioxidant-based strategies to prevent or halt the disease progression. Nerolidol, a strong antioxidant, possesses various biological activities and properties that treat cardiotoxicity, nephrotoxicity, neurotoxicity, and many other diseases. Many recent publications and research studies highlight the beneficial effect of nerolidol on brain disorders. In Alzheimer’s disease, nerolidol shows neuroprotection by decreasing amyloid plaque formation, lipid peroxidation, cholinergic neuronal loss, locomotor dysfunction, neuroinflammation, and hippocampal damage via enhancing antioxidant expression. Also, it shows neuroprotection against rotenone-induced neurotoxicity by inhibiting microglial activation. Another study reported that nerolidol shows antiepileptic effects in animal models by suppressing kindling-induced memory impairment by decreasing oxidative stress. It has been found that NRL administration increases the antioxidant levels, decreasing the pro-inflammatory cytokine release as well as decreasing the apoptotic protein and cerebral infarct size. In conclusion, nerolidol tends to reverse the harmful effects of disease-related factors, including OS, neuroinflammation, protein aggregation, and apoptosis, making nerolidol a choiceable drug for the management of neurological disorders. The purpose of this review is to discuss the mechanism of nerolidol in treating various neurological disorders.

Cervical cancer has become a major worldwide health concern that demands attention to women's health and often needs more effective and specialized treatment options. Cervical cancer claims the lives of over 300,000 women globally, ranking as the fourth most prevalent cancer among women. The tumor microenvironment (TME) shapes a distinctive landscape for tumor survival, characterized by factors like immunosuppression, hypoxia, acidity, and nutrient scarcity. Comprising tumor cells, immune cells, mesenchymal cells, cancer-associated fibroblasts, and extracellular matrix, the TME reprograms key aspects of tumor development, uncontrolled proliferation, invasion, metastasis, and response to treatments. Recognizing the TME's pivotal role in tumor progression and treatment responsiveness, targeting the TME has emerged as a potential strategy in cancer therapy. This publication delves into recent TME research, offering a comprehensive overview of the specific functions of each TME component in cancer development and progression. Based on the reviewed literature, it appears that women with cervical cancer may benefit from more effective therapy, fewer side effects, and a higher quality of life in the future. By addressing pressing problems and unmet needs in the field, this review has the potential to significantly alter the course of cervical cancer treatment in the future. Furthermore, it outlines the primary therapeutic targets identified by researchers, which may prove valuable in treating tumors.

The human microbiota represents the community and diverse population of microbes within the human body, which comprises approximately 100 trillion micro-organisms. They exist in the human gastrointestinal tract and various other organs and are now considered virtual body organs. It is mainly represented by bacteria but also includes viruses, fungi, and protozoa. Although there is a heritable component to the gut microbiota, environmental factors related to diet, drugs, and anthropometry determine the composition of the microbiota. Besides the gastrointestinal tract, the human body also harbours microbial communities in the skin, oral and nasal cavities, and reproductive tract. The current review demonstrates the role of gut microbiota and its involvement in processing food, drugs, and immune responses. The discussion focuses on the implications of human microbiota in developing several diseases, such as gastrointestinal infections, metabolic disorders, malignancies, etc., through symbiotic relationships. The microbial population may vary depending on the pathophysiological condition of an individual and thus may be exploited as a therapeutic and clinical player. Further, we need a more thorough investigation to establish the correlation between microbes and pathophysiology in humans and propose them as potential therapeutic targets.

Fungal infections contribute to over 1.5 million fatalities each year, with cutaneous mycoses standing as prominent global infections. The spectrum of these mycoses varies widely, encompassing enduring afflictions like ringworm, localized infections such as tinea capitis, recurrent instances like vaginal candidiasis, and potentially fatal systemic infections impacting multiple organ systems. The escalating recognition of the health and socioeconomic ramifications associated with fungal pathogens underscores their importance in contemporary discourse. On a global scale, projections indicate that over 300 million individuals experience significant fungal infections annually, resulting in a mortality rate exceeding 1.5 million deaths per year. Alarmingly, resistance to commonly used antifungal drugs was on the rise, with some reports suggesting that over 10% of Candida bloodstream isolates worldwide were resistant to fluconazole, a commonly prescribed antifungal medication. Therefore, there is an immediate need to increase the accessibility of new antifungal medications while minimizing their costs and adverse effects. Fungi, as heterotrophic organisms, acquire nutrients through absorption. Their filamentous structure, composed of hyphae, facilitates efficient nutrient uptake by secreting enzymes that break down complex organic matter into simpler compounds. These organisms exhibit remarkable adaptability in responding to environmental cues, adjusting growth rates, and altering morphological features. Fungi regulate their metabolism intricately, undergoing various metabolic pathways for energy production and utilizing diverse substrates for respiration. Additionally, they exhibit distinctive reproductive strategies, employing both sexual and asexual modes of reproduction, contributing to their genetic diversity and resilience in diverse ecosystems. We now have more information than ever on the origins of infection as well as the physiology of fungi cells, giving us the chance to use it to produce new generations of antifungals. This review includes various novel antifungal drug targets showing their possible effects via different mechanisms aiming at vital functions like GPI synthesis, cell wall synthesis, hyphal growth, and other essential pathways responsible for fungal growth.

Plant fibers are strong, robust, flexible, versatile, renewable, and sustainable, making them valuable for many applications. Fibers from plants are now utilized in biomedical appli-cations as reinforcements for biological composites to enhance the mechanical characteristics of composite biological materials including rigidity, tensile strength, and endurance. Reinforcement composites with hybrid components were explored in biodevices for prospective utilization in orthopedics, prosthetics, tissue fabrication, and surgical dressings. This review presents an overview of plant fibers, including their characteristics, influencing variables, and numerous applications. The text explores several methods for creating synthetic composites using common, sustainable fibers and the distinct characteristics of the resulting biological materials. The text also analyses many instances of composite hybrids and their application in the biological field. The results are summarised and suggestions for potential improvements are presented. The current research primarily examines the concept, specifications, efficiency, and potential advancements of composites with hybrid characteristics made from plant fibers.

Pharmaceutical research is increasingly focusing on transdermal drug delivery due to its potential for improved compliance and bioavailability. However, it is challenging due to the tight intracellular junctions present in the skin. Researchers have developed noninvasive methods, like transfersomes, to overcome these challenges. Transfersomes are ultra-deformable vesicles utilized for improved transdermal applications. They are made up of a phospholipid-rich lipid bilayer, an edge activator, and an ethanol/aqueous core. After topical treatment, transfersomes can penetrate deeper skin regions, delivering larger concentrations of active compounds. A transfersomal patch is applied to the skin and left for an extended period of time to allow a large dose of medication to permeate into the bloodstream. The transfersomal patch offers an advantage over the transfersomal gel because it allows the transfersomes to be applied under occlusive conditions, resulting in greater permeability, a lower amount of active medication, and a steady supply rather than a massive dose. This review represents the preparation and evaluation of transfersomal patches, recent research approaches, and future aspects of transfersomal patches. This study suggests that drug-loaded transfersomal patches could be a unique option to avoid invasive therapy.
