They encapsulated the drug compound into nanoparticles that were designed to accumulate in lymphatic vessels and then release the drug in a localized manner. So far, the approach seems to help kickstart the vessels into doing their job in moving fluid. \u00a0\u00a0\u00a0\u00a0<\/p>\n<p>Lymphatic vessels can become damaged through injury, or in some cases from the side-effects of cancer therapy or surgery. This impairment can result in localized fluid retention that is uncomfortable and can be difficult to treat. Previously, researchers have focused on trying to regrow new lymph vessels, but this latest research showcases a simpler approach and instead focuses on improving the action of the existing vessels.<!-- ASYNC UAT M - 300x250(t,r) - --><\/p>\n<p><!-- END ASYNC UAT M - 300x250(t,r) --><\/p>\n<p>\u201cWith many patients, the challenge is that the lymphatic vessels that still exist in the patient aren\u2019t working. So it\u2019s not that you need to grow new vessels that you can think of as tubes, it\u2019s that you need to get the tubes to work, which for lymphatic vessels means to pump,\u201d said Brandon Dixon, a researcher involved in the study. \u201cThat\u2019s where our approach is really different. It delivers a drug to help lymphatic vessels pump using a nanoparticle that can drain into the diseased vessels themselves.\u201d<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-large\"><img class=\"lazy lazy-hidden\" decoding=\"async\" data-lazy-type=\"image\" src=\"https:\/\/research.gatech.edu\/sites\/default\/files\/inline-images\/Blank-NP-Pumping_0.gif\" alt=\"\"\/><noscript><img decoding=\"async\" src=\"https:\/\/research.gatech.edu\/sites\/default\/files\/inline-images\/Blank-NP-Pumping_0.gif\" alt=\"\"\/><\/noscript><figcaption class=\"wp-element-caption\"><em>Near infrared video of lymphatic contractile activity in model delivered empty nanoparticles<em>.<\/em><\/em><\/figcaption><\/figure>\n<\/div>\n<p>So, why can\u2019t a patient simply take the drug orally or intravenously? Well, the compound, called S-(-)-Bay K8644, targets calcium channels that are involved in muscle contraction in endocrine, cardiac, or skeletal tissues. Allowing the drug to spread unchecked throughout the body could lead to a host of unpleasant side-effects including convulsions.<\/p>\n<p>To address this, the researchers encapsulated the compound into nanoparticles that are designed to accumulate in the lymph system and then release the drug gradually, precisely where it is needed. \u201cLymphatic tissues work like river basins \u2014 regionally you have vessels that drain the fluid out of your tissues,\u201d said Susan Thomas, another researcher involved in the study. \u201cThis method is like putting nanoparticles in the river to help the river flow better.\u201d \u00a0<\/p>\n<p>Study in journal <em>Science Advances<\/em>: Lymphatic-draining nanoparticles deliver Bay K8644 payload to lymphatic vessels and enhance their pumping function<\/p>\n<p>Via: Georgia Institute of Technology<\/p>\n<p><!--TrendMD v2.4.8--><\/div>\n<p><script>(function(d, s, id) {\n var js, fjs = d.getElementsByTagName(s)[0];\n if (d.getElementById(id)) return;\n js = d.createElement(s); js.id = id;\n js.src = \"\/\/connect.facebook.net\/en_US\/sdk.js#xfbml=1&version=v2.4&appId=2624537092\";\n fjs.parentNode.insertBefore(js, fjs);\n}(document, 'script', 'facebook-jssdk'));<\/script><br \/>\n<br \/><br \/>\n<br \/><a href=\"https:\/\/www.medgadget.com\/2023\/03\/nanoparticles-get-lymphatic-vessels-pumping.html\" target=\"_blank\" rel=\"noopener\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at the Georgia Institute of Technology have developed a nanotechnological solution for lymphedema, a failure of the lymphatic system that results in uncomfortable and [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":12495,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_mi_skip_tracking":false,"footnotes":""},"categories":[23],"tags":[],"_links":{"self":[{"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/posts\/12494"}],"collection":[{"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/comments?post=12494"}],"version-history":[{"count":0,"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/posts\/12494\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/media\/12495"}],"wp:attachment":[{"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/media?parent=12494"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/categories?post=12494"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ultimatehealthreport.com\/wp-json\/wp\/v2\/tags?post=12494"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
