Selaru, M.D., director of the Johns Hopkins Inflammatory Bowel Disease Center, led a team of researchers and biomedical engineers that designed and tested shape-changing microdevices that mimic the way the parasitic hookworm affixes itself to an organism\u2019s intestines.<\/p>\n<p>Made of metal and thin, shape-changing film and coated in a heat-sensitive paraffin wax, \u201ctheragrippers,\u201d each roughly the size of a dust speck, potentially can carry any drug and release it gradually into the body.<\/p>\n<p>The team published results of an animal study this week as the cover article in the journal\u00a0<em>Science Advances<\/em>.<\/p>\n<p>Gradual or extended release of a drug is a long-sought goal in medicine. Selaru explains that a problem with extended-release drugs is they often make their way entirely through the\u00a0<a href=\"https:\/\/medicalxpress.com\/tags\/gastrointestinal+tract\/\">gastrointestinal tract<\/a>\u00a0before they\u2019ve finished dispensing their medication.<\/p>\n<p>\u201cNormal constriction and relaxation of GI tract muscles make it impossible for extended-release drugs to stay in the intestine long enough for the patient to receive the full dose,\u201d says Selaru, who has collaborated with Gracias for more than 10 years. \u201cWe\u2019ve been working to solve this problem by designing these small drug carriers that can autonomously latch onto the\u00a0<a href=\"https:\/\/medicalxpress.com\/tags\/intestinal+mucosa\/\">intestinal mucosa<\/a>\u00a0and keep the drug load inside the GI tract for a desired duration of time.\u201d<\/p>\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/scx1.b-cdn.net\/csz\/news\/800\/2020\/17-researcherse.jpg\" alt=\"Researchers engineer tiny machines that deliver medicine efficiently\" \/><figcaption>When an open theragripper, left, is exposed to internal body temperatures, it closes on the instestinal wall.

When the paraffin wax coating on the grippers reaches the temperature inside the body, the devices close autonomously and clamp onto the colonic wall. The closing action causes the tiny, six-pointed devices to dig into the mucosa and remain attached to the colon, where they are retained and release their medicine payloads gradually into the body. Eventually, the theragrippers lose their hold on the tissue and are cleared from the intestine via normal gastrointestinal muscular function.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-videopress wp-embed-aspect-4-3 wp-has-aspect-ratio\">\n<div class=\"wp-block-embed__wrapper\"><iframe loading=\"lazy\" src=\"https:\/\/video.wordpress.com\/embed\/tZ71HjE1?preloadContent=metadata&amp;hd=1\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" data-mce-fragment=\"1\"><\/iframe><\/div><figcaption>Taken from the original research annexes<\/figcaption><\/figure>\n<p>Gracias notes advances in the field of biomedical engineering in recent years.<\/p>\n<p>\u201cWe have seen the introduction of dynamic, microfabricated smart devices that can be controlled by electrical or chemical signals,\u201d he says. \u201cBut these grippers are so small that batteries, antennas and other components will not fit on them.\u201d<\/p>\n<p>Theragrippers, says Gracias, don\u2019t rely on electricity, wireless signals or external controls. \u201cInstead, they operate like small, compressed springs with a temperature-triggered coating on the devices that releases the stored energy autonomously at\u00a0<a href=\"https:\/\/medicalxpress.com\/tags\/body\/\">body<\/a>\u00a0temperature.\u201d<\/p>\n<p>The Johns Hopkins researchers fabricated the devices with about 6,000 theragrippers per 3-inch silicon wafer.

However, intranasal administration produces quite low drug concentrations in the brain due limited nasal mucosal permeability and the harsh nasal cavity environment.

Current anti-HIV drugs, although effective in reducing plasma viral levels, cannot eradicate the virus completely from the body. The low permeability of anti-HIV drugs across the blood-brain barrier (BBB) leads to insufficient delivery. Therefore, developing a novel approaches enhancing the CNS delivery of anti-HIV drugs are required for the treatment of neuro-AIDS. The aim of this study was to develop intranasal nanoemulsion (NE) for enhanced bioavailability and CNS targeting of saquinavir mesylate (SQVM). SQVM is a protease inhibitor which is a poorly soluble drug widely used as antiretroviral drug, with oral bioavailability is about 4%. The spontaneous emulsification method was used to prepare drug-loaded o\/w nanoemulsion, which was characterized by droplet size, zeta potential, pH, drug content. Moreover, ex-vivo permeation studies were performed using sheep nasal mucosa. The optimized NE showed a significant increase in drug permeation rate compared to the plain drug suspension (PDS). Cilia toxicity study on sheep nasal mucosa showed no significant adverse effect of SQVM-loaded NE. Results of in vivo biodistribution studies show higher drug concentration in brain after intranasal administration of NE than intravenous delivered PDS. The higher percentage of drug targeting efficiency (% DTE) and nose-to-brain drug direct transport percentage (% DTP) for optimized NE indicated effective CNS targeting of SQVM via intranasal route. Gamma scintigraphy imaging of the rat brain conclusively demonstrated transport of drug in the CNS at larger extent after intranasal administration as NE.<\/p>\n<h2>SIMILAR ARTICLES<\/h2>\n<ul id=\"similar-articles-list\">\n<li><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/18455333\/\">Intranasal nanoemulsion based brain targeting drug delivery system of risperidone.<\/a>\u00a0Kumar M, Misra A, Babbar AK, Mishra AK, Mishra P, Pathak K.

Many experiments in animal models have shown that nanoscale carriers have the ability to enhance the nasal delivery of peptide\/protein drugs and vaccines compared to the conventional drug solution formulations. However, the rapid mucociliary clearance of the drug-loaded nanoparticles can cause a reduction in bioavailability percentage after intranasal administration. Thus, research efforts have considerably been directed towards the development of hydrogel nanosystems which have mucoadhesive properties in order to maximize the residence time, and hence increase the period of contact with the nasal mucosa and enhance the drug absorption. It is most certain that the high viscosity of hydrogel-based nanosystems can efficiently offer this mucoadhesive property. This update review discusses the possible benefits of using hydrogel polymer-based nanoparticles and hydrogel nanocomposites for drug\/vaccine delivery through the intranasal administration.<\/p>\n<p><strong>Keywords:<\/strong>\u00a0Brain; Hydrogel; Nanoparticles; Nasal delivery; Vaccine.<\/p>\n<h2>SIMILAR ARTICLES<\/h2>\n<ul id=\"similar-articles-list\">\n<li><a href=\"https:\/\/silview.media\/19121350\/\">Nanoparticles for nasal vaccination.\u00a0<\/a>Csaba N, Garcia-Fuentes M, Alonso MJ.Csaba N, et al.Adv Drug Deliv Rev. 2009 Feb 27;61(2):140-57. doi: 10.1016\/j.addr.2008.09.005.
