Endovascular repair and open repair surgery of thoraco-abdominal aortic aneurysms cause drastically different types of spinal cord injury.

Sci Rep 2021 Apr 9;11(1):7834. Epub 2021 Apr 9.

Department of Surgery, Division of Vascular and Endovascular Surgery, Eastern Virginia Medical School, 600 Gresham Dr, Norfolk, VA, 23507, USA.

Both endovascular repair (EVR) and open repair (OR) surgery of thoraco-abdominal aortic aneurysms cause spinal cord (SC) injury that can lead to paraparesis or paraplegia. It has been assumed that mechanisms responsible for SC damage after EVR are similar to those after OR. This pilot study compared the pathophysiology of SC injury after EVR versus OR using a newly developed EVR dog model. Read More

Six-fold increase of atmospheric pCO during the Permian-Triassic mass extinction.

Nat Commun 2021 Apr 9;12(1):2137. Epub 2021 Apr 9.

Department of Earth and Environmental Studies, Montclair State University, Montclair, NJ, USA.

The Permian-Triassic mass extinction was marked by a massive release of carbon into the ocean-atmosphere system, evidenced by a sharp negative carbon isotope excursion. Large carbon emissions would have increased atmospheric pCO and caused global warming. However, the magnitude of pCO changes during the PTME has not yet been estimated. Read More

Department of Emergency Medicine, Nagayama Hospital, 1-1-10 Okubohigashi, Kumatori, Osaka, 590-0406, Japan.

Black esophagus is a rare condition referred from acute necrosis of the esophagus, with characteristic endoscopic finings of circumferential black appearance of the mucosa. Black esophagus is associated with systemic dysfunction, such as massive bleeding, or severe dehydration. Although the duodenal mucosa is also susceptible to ischemia, reports of black esophagus with duodenal involvement, such as bleeding or perforation, are limited. Read More

Distribution of genetic elements associated with antibiotic resistance in treated and untreated animal husbandry waste and wastewater.

Environ Sci Pollut Res Int 2021 Apr 9. Epub 2021 Apr 9.

Department of Biological Sciences, Federal University of Ouro Preto, Campus Morro do Cruzeiro, Ouro Preto, State of Minas Gerais, CEP: 35.400-000, Brazil.

Animal breeding for meat production based on swine, cattle, poultry, and aquaculture is an activity that generates several impacts on the environment, among them the spread of antibiotic resistance. There is a worldwide concern related to the massive use of antibiotics, which causes selective pressure on the microbial community, triggering bacteria that contain "antibiotic resistance genes." According to the survey here presented, antibiotic resistance-related genes such as tetracyclines (tet), erythromycin (erm), and sulfonamides (sul), as well as the genetic mobile element interferon (int), are the most reported genetic elements in qualitative and quantitative studies of swine, cattle, poultry, and aquaculture manure/wastewater.

Signatures of Chaos in Nonintegrable Models of Quantum Field Theories.

Phys Rev Lett 2021 Mar;126(12):121602

Faculty of Mathematics and Physics, University of Ljubljana, Ljubljana SI 1000, Slovenia.

We study signatures of quantum chaos in (1+1)D quantum field theory (QFT) models. Our analysis is based on the method of Hamiltonian truncation, a numerical approach for the construction of low-energy spectra and eigenstates of QFTs that can be considered as perturbations of exactly solvable models. We focus on the double sine-Gordon, also studying the massive sine-Gordon and ϕ^{4} model, all of which are nonintegrable and can be studied by this method with sufficiently high precision from small to intermediate perturbation strength.

Conformational Dynamics of Sclerostin-LRP6 Complex Analyzed by HDX-MS.

Biomol Ther (Seoul) 2021 Apr 9. Epub 2021 Apr 9.

School of Pharmacy, Sungkyunkwan University, Suwon 16419, Republic of Korea.

Sclerostin (SOST), a regulator of bone formation in osteocytes, inhibits the canonical Wnt signaling by interacting with low-density lipoprotein receptor-related protein 5/6 (LRP5/6) to prevent Wnt binding. Loss-of-function mutations of the gene caused massive bone outgrowth and SOST-null mouse exhibited a high bone density phenotype. Therefore, SOST has been suggested as a promising therapeutic target for osteoporosis. Read More

Carnosine functionalized magnetic metal-organic framework nanocomposites for synergistic enrichment of phosphopeptides.

Anal Chim Acta 2021 May 12;1157:338383. Epub 2021 Mar 12.

College of Chemistry, Jilin University, Changchun, 130012, China; Key Laboratory for Molecular Enzymology and Engineering of Ministry of Education, College of Life Sciences, Jilin University, Changchun, 130012, China. Electronic address:

Protein phosphorylation regulates the conformations and function of proteins, which plays an important part in organisms. However, systematic and in-depth analysis of phosphorylation often hinders on account of the low abundance and suppressed ionization of phosphopeptides. Various materials based on single enrichment mechanism show potential in phosphopeptides enrichment, but the enrichment performance is typically not satisfactory. Read More

State predictive information bottleneck.

J Chem Phys 2021 Apr;154(13):134111

Department of Chemistry and Biochemistry and Institute for Physical Science and Technology, University of Maryland, College Park, Maryland 20742, USA.

The ability to make sense of the massive amounts of high-dimensional data generated from molecular dynamics simulations is heavily dependent on the knowledge of a low-dimensional manifold (parameterized by a reaction coordinate or RC) that typically distinguishes between relevant metastable states, and which captures the relevant slow dynamics of interest. Methods based on machine learning and artificial intelligence have been proposed over the years to deal with learning such low-dimensional manifolds, but they are often criticized for a disconnect from more traditional and physically interpretable approaches. To deal with such concerns, in this work we propose a deep learning based state predictive information bottleneck approach to learn the RC from high-dimensional molecular simulation trajectories.

Treatment challenges in patients with early acute massive pulmonary thrombosis embolism (PTE) after lung cancer surgery: A case report.

Medicine (Baltimore) 2021 Apr;100(14):e25371

Department of Respiratory and Critical Care Medicine, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China.

Introduction: Early acute massive pulmonary thrombosis embolism (PTE) after lung cancer surgery is one of the most fatal surgical complications. It is often accompanied by shock and hypotension, with high mortality rate. Due to surgical wounds, patients with early acute massive PTE after lung cancer surgery have a high risk of thrombolytic bleeding, which renders treatment more challenging and there is currently no standard protocol on how to safely and effectively treat these patients in the clinic.
