Nanogels open up access to a wide range of applications and offer among others hopeful approaches for use in the field of biomedicine. This review provides a brief overview of current developments of nanogels in general, particularly in the fields of drug delivery, therapeutic applications, tissue engineering, and sensor systems. Specifically, cyclodextrin (CD)-based nanogels are important because they have exceptional complexation properties and are highly biocompatible.

However, the only nanoparticle available for clinical applications to date, ferumoxytol, has caused rare but severe anaphylactic reactions. MegaPro nanoparticles (MegaPro-NPs) provide an improved safety profile.

Available pharmaceuticals provide temporary symptomatic relief without affecting disease progression. Use of radiation was found effective in treating extra-cranial amyloidosis, therefore, the present study was designed to investigate the neuroprotective role of fractionated X-irradiation in Aβ-based rodent model of Alzheimer's disease.

The aim of the study was to assess the hepatotoxicity, and therefore pharmacological safety of probiotics Lactobacillus plantarum (AdF10) and Lactobacillus rhamnosus GG (LGG) for potential use in colorectal cancer (CRC) prevention. Thirty-six female Sprague Dawley (SD) rats were divided into six groups: normal control, AdF10-treated, LGG-treated, 1,2-Dimethyl hydrazine (DMH)-treated, AdF10 + DMH-treated, and LGG + DMH-treated groups. Antioxidant enzyme activity, lipid proxidation, and liver function were assessed.

The present study was undertaken to optimize the dose of lithium, with an aim to increase the retention of I-131 in the thyroid follicles while maintaining the euthyroid state. 24 female Wistar rats weighing 110 ± 20 g were segregated into four groups. Animals in group I were fed standard laboratory feed and water throughout the period of experimentation.

Aim: To assess the impact of probiotics in preventing induction of colon carcinogenesis in rats.
When tagged with a suitable radionuclide, the cancer targeting properties of trans-resveratrol could be utilized to locate cancerous sites in the body using radionuclide imaging technique. However, the polyphenol due to its rapid and extensive metabolism exhibits low bioavailability in vivo. The study was designed to enhance the cancer targeting efficacy of radiolabeled resveratrol using nano-based technology.

The rats were divided into 6 groups viz., normal control, Lactobacillus plantarum (AdF10) treated, Lactobacillus rhamnosus GG (LGG) treated, DMH treated, AdF10 + DMH treated and LGG + DMH treated.

The present study was conducted to understand the influence of zinc on bone mineral metabolism in prednisolone-treated rats. Disturbance in bone mineral metabolism was induced in rats by subjecting them to prednisolone treatment for a period of 8 weeks. Female rats aged 6-8 weeks weighing 150 to 200 g were divided into four treatment groups, viz.

This study optimized the radiolabeling of cisplatin with technetium-99m (99mTc) and evaluated its biodistribution in an experimental model of lung carcinogenesis. The percentage labeling of cisplatin with 99mTc was assessed using an ascending chromatographic technique. For biodistribution studies, male rats were divided into 2 groups.
