Dermatological disease states have psychological impacts that affect a patient's life. In the management of such disorders, topical delivery has an important role. However, the conventional topical delivery systems suffer from various limitations, like skin irritation, a minute quantity of drugs reaching disease sites, and over and under medication, which leads to an adverse reaction and therapeutic failure, respectively. Therefore, researchers continuously search for an alternate delivery system for treating skin disease. In recent years, nanostructured lipid carriers (NLC) have emanated as promising carrier systems for topical delivery. The current review provides an in-depth insight into topical administration for treating a variety of dermatological issues using NLCs as a carrier. This review highlights the suitability of NLCs as carriers for topical delivery, their method of preparation, and their characterization. In the present review, the main emphasis has been given to the management of various dermatological problems by using NLCs as a carrier; a plethora of literature investigating NLC as the carrier for topical delivery has been included in this review. In this paper, an attempt has been made to provide a summary of the research carried out in this field that will encourage further research in this arena.

Background: Although cancers emerge rapidly and cancer cells divide aggressively, which affects our vital organ systems. Recently, cancer treatments are targeted immune systems mediating intrinsic cellular mechanisms. Natural efficacious polyphenols have been exhibited to help prevent most cancers and reverse the progression of cancers.Methods: Many resources have been used to know the promising role of polyphenols in preventing and treating cancers. The electronic databases include Science Direct, Google, Google Scholar, PubMed, and Scopus. The search was limited to the English language only.Results: Polyphenols have been reported as anti-metastatic agents that explore the promising role of these compounds in cancer prevention. Such agents act through many signaling pathways, including PI3K/Akt and TNF-induced signaling pathways. The chemical modifications of polyphenols and the structure-activity relationships (SARs) between polyphenols and anticancer activities have also been discussed.Conclusion: Many research papers were reported to explain the anti-cancer potential of Polyphenols, The SARs between polyphenols and anti-cancer activities, which correlate structures of polyphenols with significant chemotherapeutic action. The mechanism of anti-cancer potential is to be added for searching for new anti-cancer natural products.

Background: The disease of the posterior segment of the eye is a major concern worldwide, and it affects more than 300 million people and leads to serious visual deterioration. The current treatment available is invasive and leads to serious eye complications. These shortcomings and patient discomfort lead to poor patient compliance. In the last decade, Nanostructured lipid carriers (NLC) have established a remarkable milestone in the delivery of drug substances to the posterior segment of the eye. Additionally, NLC can reduce the clearance due to adhesive properties which are imparted due to nano-metric size. This attribute might reduce the adverse effects associated with intravitreal therapy and thus enhance therapeutic efficacy, eventually raising patient adherence to therapy. The current review provides an inclusive account of NLC as a carrier to target diseases of the posterior segment of the eye.Objective: The review focuses on the various barrier encountered in the delivery of drugs to the posterior segment of the eye and the detail about the physicochemical property of drug substances that are considered to be suitable candidates for encapsulation to lipid carriers. Therefore, a plethora of literature has been included in this review. The review is an attempt to describe methods adopted for assessing the in-vivobehavior that strengthens the potential of NLC to treat the disease of the posterior segment of the eye.Conclusion: These NLC-based systems have proven to be a promising alternative in place of invasive intravitreal injections with improved patient compliance.
