RESUMO

Modern medicine relies on a small number of key biologics, which can be found in nature but require further characterization and purification before they can be used. Since the herbal remedy is given through a dated and ineffective method of drug administration, its effectiveness is diminished. The novel form of medicine delivery has the potential to increase the effectiveness of herbal substances while decreasing their side effects. This is the main idea behind utilising different ways of drug delivery in herbal treatments. Several benefits arise from novel formulations of herbal compounds as compared to their conventional counterparts. These include enhanced penetrating ability into tissues, constant delivery of effective doses, and resistance to physical and chemical degradation. Controlled and targeted delivery that include herbal components allow for more traditional dosing while simultaneously increasing their efficacy. Enhancing the biodistribution and target site accumulation of systemically administered herbal medicines is the goal of nanomedicine formulations. The field of nanotheranostics has made significant advancements in the development of herbal compounds by combining diagnostic and therapeutic functions on a single nanoscale platform. It is critically important to create a theranostic nanoplatform that is derived from plants and is intrinsically "all-in-one" for single molecules. In addition to examining the mechanistic approach to nanoparticle synthesis, this review highlights the therapeutic effects of nanoscale phytochemical delivery systems. Furthermore, we have evaluated the scope for future advancements in this field, discussed several nanoparticles that have been developed recently for herbal imaging, and provided experimental evidence that supports their usage.

RESUMO

Cardiovascular disease is one of the chief factors that cause ischemic stroke, myocardial infarction, and venous thromboembolism. The elements that speed up thrombosis include nutritional consumption, physical activity, and oxidative stress. Even though the precise etiology and pathophysiology remain difficult topics that primarily rely on traditional medicine. The diagnosis and management of thrombosis are being developed using discrete non-invasive and non-surgical approaches. One of the emerging promising approach is ultrasound and photoacoustic imaging. The advancement of nanomedicines offers concentrated therapy and diagnosis, imparting efficacy and fewer side effects which is more significant than conventional medicine. This study addresses the potential of nanomedicines as theranostic agents for the treatment of thrombosis. In this article, we describe the factors that lead to thrombosis and its consequences, as well as summarize the findings of studies on thrombus formation in preclinical and clinical models and also provide insights on nanoparticles for thrombus imaging and therapy.

RESUMO

Colorectal cancer (CRC) is a serious disease that affects millions of people throughout the world, despite considerable advances in therapy. The formation of colorectal adenomas and invasive adenocarcinomas is the consequence of a succession of genetic and epigenetic changes in the normal colonic epithelium. Genetic and epigenetic processes associated with the onset, development, and metastasis of sporadic CRC have been studied in depth, resulting in identifying biomarkers that might be used to predict behaviour and prognosis beyond staging and influence therapeutic options. A novel biomarker, or a group of biomarkers, must be discovered in order to build an accurate and clinically useful test that may be used as an alternative to conventional methods for the early detection of CRC and to identify prospective new therapeutic intervention targets. To minimise the mortality burden of colorectal cancer, new screening methods with higher accuracy and nano-based diagnostic precision are needed. Cytotoxic medication has negative side effects and is restricted by medication resistance. One of the most promising cancer treatment techniques is the use of nano-based carrier system as a medication delivery mechanism. To deliver cytotoxic medicines, targeted nanoparticles might take advantage of differently expressed molecules on the surface of cancer cells. The use of different compounds as ligands on the surface of nanoparticles to interact with cancer cells, enabling the efficient delivery of antitumor medicines. Formulations based on nanoparticles might aid in early cancer diagnosis and help to overcome the limitations of traditional treatments, including low water solubility, nonspecific biodistribution, and restricted bioavailability. This article addresses about the molecular pathogenesis of CRC and highlights about biomarkers. It also provides conceptual knowledge of nanotechnology-based diagnostic techniques and therapeutic approaches for malignant colorectal cancer.
