Recurrent Polymicrobial Bloodstream Infections As Harbingers Of A Duodenal-Inferior Vena Cava Fistula, Gregory E. Koval, Richard J. Hankins, Jasmine R. Marcelin

Graduate Medical Education Research Journal

This is a case of an 82-year-old patient who presented with recurrent polymicrobial bloodstream infections and no obvious undrained source of infection. She had prior double barrel iliocaval stenting for post thrombotic syndrome. The patient underwent exploratory laparotomy and primary repair of a duodenal-caval fistula with a fascia lata patch and an omental pedicle flap. No further bloodstream infections were documented after the repair. This discussion highlights an uncommon complication of IVC stenting, its presentation as well as the operative approach used to repair the fistula.

Information-Rich 6d Single-Molecule Imaging Design Using Optimization, Tingting Wu

McKelvey School of Engineering Graduate Student Theses & Dissertations

When studying biochemical processes, localizing the targets alone will not paint a complete picture. We also need techniques to probe how biomolecules interact with one another, including how molecules are organized into larger structures, how they are oriented with respect to surrounding molecules, and how local chemical parameters, like pH and hydrophobicity, vary spatially and temporally. My dissertation focuses on single-molecule orientation localization microscopy (SMOLM, Chapter 1). The objective is to develop imaging techniques for measuring how molecules are oriented with respect to their surrounding molecules, namely, 3D orientation. Achieving optimal imaging performance requires careful design of both the forward …

Putin Skirts The Icc: The Invasion Of Ukraine And The Symbolic Power Of International Law, Corbin Gregg

Cardozo International & Comparative Law Review (CICLR) Blog

Much can be said about the role of international law in shaping the behavior of states and leaders. Often maligned, international organizations face criticism from those who wish to see them do more: punish human rights violations, sanction aggressive state actors, and prevent wars of aggression. While these are overall purported goals of international organizations, the way they attempt to effectuate change is sometimes unclear. Nowhere is this more true than the way the international organizations have reacted to the Russian invasion of Ukraine.

Effect Of Different Processing Temperature On Texture Profile And Flavor Of The Edible Bird's Nest, Shang Kexin, Qiu Shuang, Zhang Lan, Cheng Xiangrong, Wang Dongliang

Food and Machinery

Objective: This study aimed to investigate the effects of different processing temperature on texture profile and flavor of dried edible bird's nest. Methods: With dried edible bird's nest as the main raw material, the texture profile analysis of edible bird's nest at different processing temperature was carried out by physical property analyzer. The volatile components of edible bird's nest at different processing temperature were determined by electronic nose and solid phase microextraction gas chromatography-mass spectrometry (SPME-GC-MS). Results: It was found that the adhesion of cooked edible bird's nest decreased significantly (P<0.01), but its resilience increased significantly (P<0.05) with the increase of temperature. 12 kinds of effective flavor substances were detected in the cooked edible bird's nest by SPME-GC-MS, including: 3 alcohols, 2 aldehydes, 2 esters, 3 ketones, 1 acid, and 1 ether, accounting for 6.23%, 49.34%, and 54.85% of the total detected substances in the cooked edible bird's nest at 95 ℃, 105 ℃ and 115 ℃, respectively. Conclusion: Different processing temperature affects the taste of edible bird's nest and the overall odor profile after processing. Moreover, higher cooking temperature tends to make the egg white-like flavor stronger. The volatile substances in the bird's nest stew at 95 ℃ are mainly acids, the bird's nest cooked at 105 ℃ mainly produces alcohols, and the edible bird's nest cooked at 115 ℃ mainly produces ketones and alcohols.
