    Recent advances in nanocarriers for nutrient delivery
    (Springer, 2022) Taliyan, Rajeev; Singhvi, Gautam
    For the past few years, there has been a surge in the use of nutraceuticals. The global nutraceuticals market in 2020 was USD 417.66 billion, and the market value is expected to increase by 8.9% compound annual growth rate from 2020 to 2028. This is because nutraceuticals are used to treat and prevent various diseases such as cancer, skin disorders, gastrointestinal, ophthalmic, diabetes, obesity, and central nervous system–related diseases. Nutritious food provides the required amount of nutrition to the human body through diet, whereas most of the bioactive agents present in the nutrients are highly lipophilic, with low aqueous solubility leading to poor dissolution and oral bioavailability. Also, the nutraceuticals like curcumin, carotenoids, anthocyanins, omega-3 fatty acids, vitamins C, vitamin B12, and quercetin have limitations such as poor solubility, chemical instability, bitter taste, and an unpleasant odor. Additionally, the presence of gastrointestinal (GIT) membrane barriers, varied pH, and reaction with GIT enzymes cause the degradation of some of the nutraceuticals. Nanotechnology-based nutrient delivery systems can be used to improve oral bioavailability by increasing nutraceutical stability in foods and GIT, increasing nutraceutical solubility in intestinal fluids, and decreasing first-pass metabolism in the gut and liver. This article has compiled the properties and applications of various nanocarriers such as polymeric nanoparticles, micelles, liposomes, niosomes, solid lipid nanocarriers, nanostructured lipid carrier, microemulsion, nanoemulsion, dendrimers in organic nanoparticles, and nanocomposites for effective delivery of bioactive molecules.

    Histone deacetylase inhibitors: Future therapeutics for insulin resistance and type 2 diabetes
    (Elsevier, 2016-11) Taliyan, Rajeev
    Insulin resistance is a common feature of obesity and predisposes the affected individuals to a variety of pathologies, including type 2 diabetes mellitus (T2DM), dyslipidemias, hypertension, cardiovascular disease etc. Insulin resistance is the primary cause of T2DM and it occurs many years before the disease onset. Although Thiazolidinediones (TZDs) such as rosiglitazone and pioglitazone are outstanding insulin sensitizers and are in clinical use since 1990s, however, their serious side effects such as heart attack and bladder cancer have limited their utilization. Thus, there is an unmet need to identify a new class of drugs with insulin sensitizing activity and minimal side effects. In the recent years, Histone deacetylase (HDAC) has emerged as a new molecular target in the control of insulin resistance and T2DM. The level of histone acetylation/deacetylation has been found to be altered during insulin resistance and T2DM conditions. HDAC inhibitors have been found to effectively manage insulin resistance and T2DM in various preclinical models and clinical trials. In this review we will focus on various aspects related to regulation of insulin signalling by HDACs and the future scope of HDAC inhibitors as therapeutics for insulin resistance.
