Splenic injury caused by cardiopulmonary resuscitation in a full stomach with hematoma after hemorrhagic shock due to bleeding duodenal ulcer: A case report.

Background: Cardiopulmonary resuscitation is essential for cardiopulmonary arrest, but complications from chest compressions warrant monitoring. Although rib and sternal fractures are common, abdominal injuries are rare, and splenic injuries are much rarer.

Case Presentation: A 74-year-old man was admitted to the emergency room with a hemorrhagic duodenal ulcer.

Segmental arterial mediolysis with a ruptured visceral artery on two consecutive days.

Background: We describe a case of segmental arterial mediolysis in which a vessel ruptured on two consecutive days.

Case Presentation: A 69-year-old man presented with sudden-onset abdominal pain. Computed tomography showed a hematoma in the gastric wall.

Quantum computing of Hückel molecular orbitals of π-electron systems.

In order to demonstrate an applicability of quantum computing to fundamental electronic structure problems of molecules, we describe the Hückel Hamiltonian matrix in terms of quantum gates and obtain the orbital energies of fundamental π-electron molecules (CH, CH, CH, CH, and CH) using a superconducting-qubit-type quantum computer (ibm_kawasaki) with a post-selection error mitigation method. We show that the orbital energies are obtained with sufficiently high accuracy and small uncertainties and that characteristic features of the electronic structure of the π-electron molecules can be extracted by quantum computing in a straightforward manner.

An -Fluorinated Imide for Practical Catalytic Imidations.

Catalytic imidation using NFSI as the nitrogen source has become an emerging tool for oxidative carbon-nitrogen bond formation. However, the less than ideal benzenesulfonimide moiety is incorporated into products, severely detracting its synthetic value. As a solution to this challenge, we report herein the development of a novel -fluorinated imide, -fluoro--(fluorosulfonyl)carbamate (NFC), by which the attached imide moiety acts as a modular synthetic handle for one-step derivatization to amines, sulfonamides, and sulfamides.

Safety and efficacy of cold-water immersion in the treatment of older patients with heat stroke: a case series.

Background: Heat stroke treatment focuses on rapid cooling because symptom severity correlates with the duration of hyperthermia (i.e., time during which the core body temperature is sustained above the critical threshold).

Remote MEG dipoles in focal cortical dysplasia at bottom of sulcus.

Objective: To investigate whether the magnetoencephalography (MEG) single moving dipole (SMD) method could delineate the epileptic zone of focal cortical dysplasia (FCD) at the bottom of sulcus (FCDB).

Methods: We retrospectively analyzed 17 children (11 male; mean age 8.8 years, range 3-17 years) with FCD type II who underwent epilepsy surgery.

Blockage of the early step of lankacidin biosynthesis caused a large production of pentamycin, citreodiol and epi-citreodiol in Streptomyces rochei.

In our effort to find the key intermediates of lankacidin biosynthesis in Streptomyces rochei, three UV-active compounds were isolated from mutant FS18, a gene disruptant of lkcA encoding a non-ribosomal peptide synthetase (NRPS)-polyketide synthase (PKS) hybrid enzyme. Their structures were elucidated on the basis of spectroscopic data of NMR and MS. Two compounds of a higher mobile spot on silica gel TLC (Rf=0.

Syntheses, structures and properties of 1-ethyl-3-methylimidazolium salts of fluorocomplex anions.

Fluoroacid-base reactions of a room-temperature ionic liquid, 1-ethyl-3-methylimidazolium fluorohydrogenate (EMIm(HF)2.3F, EMIm = 1-ethyl-3-methylimidazolium cation), and Lewis fluoroacids (BF3, PF5, AsF5, NbF5, TaF5 and WF6) give EMIm salts of the corresponding fluorocomplex anions, EMImBF4, EMImPF6, EMImAsF6, EMImNbF6, EMImTaF6 and EMImWF7, respectively. Attempts to prepare EMImVF6 by both the acid-base reaction of EMIm(HF)2.
