Cancer is an everyday medical concern which requires an appropriate treatment strategy. The malfunction of cell cycle is a well-established cause for cancer induction. Chemotherapy and radiation are the standard available therapeutic approach for cancer treatment; however severe side effects were reported in association to such treatments, for instance, the efficacy of patients' immune system is adversely affected in apart by radiation. These side effects may be minimized by providing novel remedial preparations. Complementary and alternative medicinal compounds, which were obtained from fresh or marine flora particularly micro and macro algae, were reported to its anti-cancerous activities. Several types of bioactive molecules are also present in microalgae, such as carotenoids, various forms of polysaccharides, vitamins, sterol, fibres, minerals…ect; the great unused biomass of microalgae and their excellent diversity of chemical constituents may introduce a major step in developing of anti-malignant drugs. Previously, such characteristic of microalgal bio-diversity was commercially exploited to make food supplements and gelling substances. However, recently, several investigations were designed to study the potential anti-carcinogenic effect of microalgal extracts, where they mostly concluded their ability to induce apoptotic cancer cell death via caspase dependent or independent pathways. In this review paper, we reported the various species of microalgae that possessed anti-tumor activity, the tumor cell lines altered through using microalgal extracts along with the levels of such extracts that reported to its inhibitor effect against cell cycle and proliferation.

Piroxicam (Px) is a non-steroidal anti-inflammatory drug that is widely prescribed in various inflammatory disorders. However, Px is known to induce gastric ulceration and hepato-renal toxicity. Rosuvastatin (ROSV), a member of the statin family, has anti-inflammatory and antioxidant actions independent of its anti-hyperlipidemic action. Therefore, we investigated the protective effects of ROSV against Px-induced gastric, liver, and kidney injury. Five groups of seven rats each were used; control group, ROSV group (20 mg/kg, given orally), Px group (7 mg/kg, given intraperitoneally), Px+ROSV L (7 and 10 mg/kg, respectively), and Px+ROSV H (7 and 20 mg/kg, respectively) group. The results revealed that Px induced severe gastric mucosal damage expressed by high ulcer index along with significant increases in liver and kidney function parameters including AST, ALT, creatinine, and urea. Disrupted lipid metabolism also was observed in Px-treated animals. Moreover, marked an increase in malondialdehyde (MDA) and decreases in glutathione (GSH) and catalase (CAT) levels along with enhanced activated caspase-3 expression in the gastric, hepatic, and renal tissues following Px-insult suggested a possible involvement of lipid peroxidation in Px-induced gastropathy and hepatorenal toxicity. However, in a dose-dependent manner, ROSV was able to mitigate Px-induced lipid peroxidation and apoptosis in gastric, liver, and kidney tissues.

Periodontitis is an inflammation-related condition, caused by an infectious microbiome and host defense that causes damage to periodontium. The natural processes of the mouth, like saliva production and eating, significantly diminish therapeutic medication residency in the region of periodontal disease. Furthermore, the complexity and diversity of pathological mechanisms make successful periodontitis treatment challenging. As a result, developing enhanced local drug delivery technologies and logical therapy procedures provides the foundation for effective periodontitis treatment. Being biocompatible, biodegradable, and easily administered to the periodontal tissues, hydrogels have sparked substantial an intense curiosity in the discipline of periodontal therapy. The primary objective of hydrogel research has changed in recent years to intelligent thermosensitive hydrogels, that involve local adjustable sol-gel transformations and regulate medication release in reaction to temperature, we present a thorough introduction to the creation and efficient construction of new intelligent thermosensitive hydrogels for periodontal regeneration. We also address cutting-edge smart hydrogel treatment options based on periodontitis pathophysiology. Furthermore, the problems and prospective study objectives are reviewed, with a focus on establishing effective hydrogel delivery methods and prospective clinical applications.

Nano carriers have gained more attention for their possible medical and technological applications. Tailored nanomaterials can transport medications efficiently to targeted areas and allow for sustained medication discharge, reducing undesirable toxicities while boosting curative effectiveness. Nonetheless, transitioning nanomedicines from experimental to therapeutic applications has proven difficult, so different pharmaceutical incorporation approaches in nano scaffolds are discussed. Then numerous types of nanobiomaterials implemented as carriers and their manufacturing techniques are explored. This article is also supported by various applications of nanobiomaterials in the biomedical field.
