This review focuses on the available targeting techniques for delivery to the colon, brain and other sites of interest. Overall, the article should make an excellent read for the researchers in this area. Newer drug targets may be identified and exploited for successful drug targeting.

Advanced formulations have been investigated to take full advantage of clays or clay-based materials. The remarkable properties of clays, such as high adsorption, high surface area, and high ion exchange capacities, provide an ideal system for the delivery of poorly water-soluble drugs. There is currently limited information on the classification and discussion of clay-based formulations for poorly water-soluble drugs. This review aims to describe efficient delivery systems that use clay as the main excipient in formulations. More details about the strategies of using clays in formulations as well as fabrication methods will be discussed. Moreover, combinations with other excipients in hybrid formulations will also be mentioned in evaluating the efficacy of these systems. The highlighted recent studies on clay-based formulations for poorly water-soluble drugs could provide fundamental approaches and prospects to apply them in drug development.

Various phenolics show inhibitory activity towards xanthine oxidase (XO), an enzyme that generates reactive oxygen species which cause oxidative damage.

This study investigated the XO inhibitory activity of Euphorbia peplus phenolics.

The dried powdered aerial parts of E. peplus were extracted, fractioned and phenolics were isolated and identified. The XO inhibitory activity of E. peplus extract (EPE) and the isolated phenolics was investigated in vitro and in vivo.

Three phenolics were isolated from the ethyl acetate fraction of E. peplus. All isolated compounds and the EPE showed inhibitory activity towards XO in vitro. In hyperuricemic rats, EPE and the isolated phenolics decreased uric acid and XO activity. Molecular docking showed the binding modes of isolated phenolics with XO, depicting significant interactions with the active site amino acid residues. Molecular dynamics simulation trajectories confirmed the interaction of isolated phenolics with XO by forming hydrogen bonds with the active site residues. Also, the root mean square (RMS) deviations of XO and phenolics-XO complexes achieved equilibrium and fluctuated during the 10 ns MD simulations. The radius of gyration and solvent accessible surface area investigations showed that different systems were stabilized at ≈ 2500 ps. The RMS fluctuations profile depicted that the drug binding site exhibited a rigidity behavior during the simulation.

In vitro, in vivo and computational investigations showed the XO inhibitory activity of E. peplus phenolics. These phenolics might represent promising candidates for the development of XO inhibitors.

Remote Ischemic Conditioning (RIC) is a safe alternative for post-stroke neuroprotetion. The present study investigated the neurorehabilitative benefits of early RIC followed by exercise (RICE) therapy.Methods 48 adult male Sprague-Dawley rats were divided into groups 1) sham, 2) stroke, 3) stroke with RICE at day 3 (RIC 6 hours after reperfusion followed by exercise days 3 to 28), 4) stroke with exercise at day 3 (exercise days 3 to 28), and 5) stroke with RICE at day 1 (RIC 6 hours after reperfusion followed by exercise days 1 to 28), 6) stroke with exercise at day 1 (exercise days 1 to 28 after reperfusion). Long-term functional outcomes were determined by grid walk, rota-rod, adhesive tape touch, and Morris water maze. Levels of mRNA and proteins of neuroplasticity, synaptogenesis, and angiogenesis, were determined.Results As compared to exercise only, animals that underwent RICE had significant improvements in functional outcomes after stroke. These improvements were most significant in groups that had the later initiation of exercise. In addition, all treatment groups showed significant increases in mRNA and protein expression of the target molecules for neuroplasticity, synaptogenesis, and angiogenesis, while further significant increases were observed after RICE following ischemic stroke.Conclusions RICE, a novel therapy that supplements RIC prior to exercise, is superiorly effective in inducing rehabilitation after stroke as compared to the traditional exercise monotherapy rehabilitation in rats with ischemic brain injury.Purpose In developed countries, diet-related health inequalities between people with different levels of socioeconomic advantage persist. Grazoprevir supplier However, there is limited qualitative evidence to inform the design of effective healthy eating (HE) strategies in socioeconomically disadvantaged populations (SDPs). The purpose of this review was to explore the characteristics influencing HE strategies for SDPs and develop a new understanding of how and why they influence their success.Methods A qualitative evidence synthesis using a systematic meta-ethnographic approach. The twelve studies included were conducted in the USA, Canada, Australia, and UK.Results The studies described a range of HE strategies, including nutrition education programs, food vouchers, and community gardens. Personal values and sense of pride and autonomy were found to have an influence on participants' attitudes towards HE strategies. Similarly, social characteristics such as level of social support and opportunities for shared benefits influenced participants' engagement.
