Recent advances in targeting malaria with nanotechnology-based drug carriers.

Malaria, as one of the most common human infectious diseases, remains the greatest global health concern, since approximately 3.5 billion people around the world, especially those in subtropical areas, are at the risk of being infected by malaria. Due to the emergence and spread of drug resistance to the current antimalarials, malaria-related mortality and incidence rates have recently increased.

Nanotechnology against the novel coronavirus (severe acute respiratory syndrome coronavirus 2): diagnosis, treatment, therapy and future perspectives.

COVID-19, as an emerging infectious disease, has caused significant mortality and morbidity along with socioeconomic impact. No effective treatment or vaccine has been approved yet for this pandemic disease. Cutting-edge tools, especially nanotechnology, should be strongly considered to tackle this virus.

Anti-Proliferative Properties, Biocompatibility, and Chemical Composition of Different Extracts of Plantago major Medicinal Plant.

Background: To study the anticancer activity of Plantago major, we assessed the effect of ethanolic, methanolic and acetonic extracts of this plant on HCT-116, SW-480, and HEK-293 cell lines as control.

Methods: The cytotoxic activity, biocompatibility, and toxicity were evaluated by MTT assay, hemolysis, and Artemia salina-LD50 (on mice) tests, respectively. The analysis of the extracts was performed by GC-MS analysis.

Establishment and elicitation of transgenic root culture of and evaluation of its anti-bacterial and cytotoxicity activity.

Hairy root induction in was optimized to take advantage of transformed root cultures. The highest frequency of transformation was achieved using leaf explant, A4 strain, pre-cultivation of explant, 150 µM Acetosyringone, 5 min inoculation, half-strength Murashige and Skoog basal medium as co-cultivation, and half-strength Gamborg's basal medium as a selective medium with 3% sucrose. Among the studied compound encompassing gallic acid, catalpol and apigenin, only the production of gallic acid in hairy roots was affected by 20 mg L AgNO and 100 mg L chitosan at 24 hr which yielded 7.

Anti-carcinogenic and anti-angiogenic properties of the extracts of on gastric cancer cells.

Objective: () has been used as a medicinal plant in Asia for its effects on digestive system for the last 2000 years. To investigate the anti-cancer activity of rhizome of , the ethanolic and methanolic extracts and essential oil of the rhizome were prepared and their effects were assessed on human gastric cancer cell line (AGS).

Materials And Methods: The viability of cells which were treated with the extracts and the essential oil was assessed by MTT assay.
