    Abstract In recent years, endovascular aneurysm repair has become the predominant method of managing abdominal aortic and common iliac artery aneurysms. Off-label use of different endovascular devices has allowed them to remain a viable option in many cases of atypical anatomy. Some studies have reported the use of iliac devices in an upside-down configuration when the common iliac artery aneurysm has a reverse-tapered morphology. However, the use of the Ovation iX (Endologix) limb in an upside-down configuration has not yet been reported. This limb offers a 14 mm distal end when inverted and offers good patency in the tortuous iliac morphology. This case report describes and illustrates the precise deployment of an inverted Ovation iX limb to treat an isolated common iliac artery aneurysm.

    Abstract The eye has anatomical structures that function as robust static and dynamic barriers, limiting the penetration, residence time, and bioavailability of medications administered topically. The development of polymeric nano-based drug-delivery systems (DDS) could be the solution to these challenges: it can pass through ocular barriers, offering higher bioavailability of administered drugs to targeted tissues that are otherwise inaccessible; it can stay in ocular tissues for longer periods of time, requiring fewer drug administrations; and it can be made up of polymers that are biodegradable and nano-sized, minimizing the undesirable effects of the administered molecules. Therefore, therapeutic innovations in polymeric nano-based DDS have been widely explored for ophthalmic drug-delivery applications. In this review, we will give a comprehensive overview of polymeric nano-based drug-delivery systems (DDS) used in the treatment of ocular diseases. We will then examine the current therapeutic challenges of various ocular diseases and analyze how different types of biopolymers can potentially enhance our therapeutic options. A literature review of the preclinical and clinical studies published between 2017 and 2022 was conducted. Thanks to the advances in polymer science, the ocular DDS has rapidly evolved, showing great promise to help clinicians better manage patients.

    Abstract The engineering of a new type of trifunctional biopolymer-based nanosponges polymerized by cross-linking beta-cyclodextrin ethylene diamine (βCD-EDA) with bifunctional hairy nanocellulose (BHNC) is reported herein. We refer to the highly cross-linked polymerized BHNC-βCD-EDA network as BBE. βCD-EDA and BHNC were cross-linked at various ratios with the help of DMTMM (4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium) as a green activator in deionized water as a solvent, which resulted in different morphological shapes of BBE. Some of these structures were chiral due to cross-linked liquid crystalline structures. A comprehensive characterization study was done to show their unique morphological, structural, and dimensional properties of BBEs. Moreover, to further investigate and to confirm the surface modification of the precursors and final BBE structures, Fourier transform infrared and nuclear magnetic resonance spectroscopy, thermogravimetric analysis, Brunauer-Emmett-Teller analysis, and X-ray diffraction were applied. The hairy nanocellulose particles were considered as the backbone, and the immobilized cyclodextrin cavities can capture doxorubicin, which was used as a model drug molecule via host-guest inclusion complexation. Finally, the obtained BBE networks showed different and sustained drug release profiles and pH responsiveness. BBE biopolymers were tested as biocompatible nanocarriers for controlled release. We realize that these structures are too big for anti-cancer drug delivery by injection or oral intake, but these structures have a high potential to be applied in wound dressing and implants. They could also be used for capturing antibiotics, dyes, and organic compounds from wastewater.
