Nanotech-based Food: An Initiative for Alternative Pharmaceuticals.

Nanotechnology opens many avenues in the food sector and offers applications associated with food production, processing, cultivation, and packaging. Nanofood employs nanotechniques like nano-encapsulation to conjugate various phytochemicals, antioxidants, probiotics, minerals, vitamins, etc., into nanovehicles. Food fortification strategies are implemented to incorporate nano-processed substances. Nanofood is mostly used for improving health and as a supplementation in various diseases ranging from liver diseases to neurodegenerative disorders. Here, we focus on recent studies that exhibit comparable results for nanofood and conventional medicines, subsiding the limitations of traditional therapies. Nanofood holds the potential for the management of various health problems and can be used as an alternative to medicine in clinical conditions, like cancers and inflammatory bowel disease. With further advances in nanotechnology and expansion in the scope of the current nanofood industry, in addition to proper regulations set in place, nanofood may offer a wide variety of advantages in terms of safety, long-term stability, etc.

Delivery systems for improving iron uptake in anemia.

Anemia poses a threat to a broad population globally as depleted hemoglobin leads to a plethora of conditions, and the most common cause includes iron deficiency. Iron is an essential element important for erythropoiesis, DNA synthesis, protection of the immune system, energy production, and cognitive function and hence should be maintained at appropriate levels. Various proteins are involved in transporting and absorption of iron, activation of heme synthesis, and RBC production that could be possible targets to improve iron delivery. Oral supplementation of iron either from dietary or synthetic sources has been the frontline therapy for treating iron deficiency in anemia. At the same time, intravenous administration is provided in chronic anemia, such as chronic kidney diseases (CKD). This review focuses on the strategies developed to overcome the disadvantages of available iron therapies and increase iron absorption and uptake in the body to restore iron content. Nanotechnology combined with the food fortification processes gained attention as they help develop new delivery systems to improve iron uptake by enterocytes. Furthermore, naturally obtained products such as polysaccharides, peptides, proteins, and new synthetic molecules have been used in fabrication of iron-carrier systems. The establishment of transdermal iron delivery systems such as microneedle arrays or iontophoresis, or the discovery of new molecules also proved to be an effective way for delivering iron in patients non-compliant to oral therapy.

Methanolic extract of Cucumis melo attenuates ethylene glycol-induced nephrolithiasis in Wistar rats.

Evaluation of the effects of methanolic extract of Cucumis melo in ethylene glycol-induced nephrolithiasis on Wistar rats. 0.75% solution of ethylene glycol (EG) in payable water was given to produce nephrolithiasis on Wistar rats. The action of oral intake of methanolic extract of Cucumis melo seed in nephrolithiasis is studied and is matched with the action of oral intake of Cystone (standard) on Wistar rats. EG resulted in hyperoxaluria and deposition of calcium oxalate as well as raised urinary excretion of oxalate and calcium. Supplementation with methanolic extract of Cucumis melo seed decreased the increased renal oxalate, indicating a regulatory effect on oxalate formation endogenously. The outcomes stipulate that the seed of Cucumis melo is endowed with antinephrolithiatic action.
