Terahertz parametric detection using a lithium tantalate.

Terahertz (THz) parametric detection is a highly sensitive method that upconverts a THz wave into a near-infrared beam for detection. Lithium niobate has primarily been used as the nonlinear optical crystal in this approach. However, the frequency band with high parametric gain is limited, leading to increasing interest in other nonlinear optical crystals.

Neutrophil adhesion to vessel walls impairs pulmonary circulation in COVID-19 pathology.

Microthrombus formation is associated with COVID-19 severity; however, the detailed mechanism remains unclear. In this study, we investigated mouse models with severe pneumonia caused by SARS-CoV-2 infection by using our in vivo two-photon imaging system. In the lungs of SARS-CoV-2-infected mice, increased expression of adhesion molecules in intravascular neutrophils prolonged adhesion time to the vessel wall, resulting in platelet aggregation and impaired lung perfusion.

Elucidation of d-allulose recognition mechanism in ketose 3-epimerase.

d-Allulose is a low-calorie sweetener with multiple nutritional functions that can be produced through d-fructose isomerization by ketose 3-epimerase (KEase). l-Ribulose 3-epimerase from Arthrobacterglobiformis (AgLRE) is one of the most important enzymes that produce d-allulose; however, its substrate recognition mechanism is unknown. In this study, the crystal structures of AgLRE and its complex with d-allulose and d-fructose were determined.

Ethanol synthesis catalytic CO hydrogenation over multi-elemental KFeCuZn/ZrO catalyst.

Technological enablers that use CO as a feedstock to create value-added chemicals, including ethanol, have gained widespread appeal. They offer a potential solution to climate change and promote the development of a circular economy. However, the conversion of CO to ethanol poses significant challenges, not only because CO is a thermodynamically stable and chemically inert molecule but also because of the complexity of the reaction routes and uncontrollability of C-C coupling.

Propane dehydrogenation catalysis of group IIIB and IVB metal hydrides.

Catalytic propane dehydrogenation (PDH) has mainly been studied using metal- and metal oxide-based catalysts. Studies on dehydrogenation catalysis by metal hydrides, however, have rarely been reported. In this study, PDH reactions using group IIIB and IVB metal hydride catalysts were investigated under relatively low-temperature conditions of 450 °C.

Review of the Japanese Classification of Esophageal Cancer 12th Edition, and Proposals for the 13th Edition.

In this review, we summarize the modifications made in the Japanese Classification of Esophageal Cancer 12th edition, identify several issues, and discuss the prospects for the next 13th edition.

Persistent pneumothorax after laparoscopic appendectomy in a patient who had undergone radical esophagectomy 5 years before: possible relationship with vulnerability of the hiatus after esophagectomy: a case report.

Postoperative pneumothorax is a well-known but relatively rare complication after laparoscopic surgery. Herein, we report a case of persistent pneumothorax after laparoscopic appendectomy. A 57-year-old male, with a history of minimally invasive esophagectomy and intrathoracic gastric tube reconstruction 5 years before, underwent a laparoscopic appendectomy.

JMJD6 Autoantibodies as a Potential Biomarker for Inflammation-Related Diseases.

Inflammation is closely associated with cerebrovascular diseases, cardiovascular diseases, diabetes, and cancers, and it is accompanied by the development of autoantibodies in the early stage of inflammation-related diseases. Hence, it is meaningful to discover novel antibody biomarkers targeting inflammation-related diseases. In this study, Jumonji C-domain-containing 6 (JMJD6) was identified by the serological identification of antigens through recombinant cDNA expression cloning.

Colonic intussusception after endoscopic mucosal resection successfully managed by endoscopic procedure.

Adult-onset intussusception, particularly associated with colonoscopy, is extremely rare. A 78-year-old man, referred to our hospital for colonic endoscopic mucosal resection (EMR), experienced subsequent dull abdominal pain, as well as elevated peripheral blood leukocytosis and C-reactive protein levels. Abdominal computed tomography (CT) revealed a colocolonic intussusception at the hepatic flexure.

Utilization of waste beverages for achieving carbon-based core-shell nanostructures of high visible light photocatalytic performance.

Waste beverages are utilized as resources in various valuable, albeit energy-consuming, waste-to-energy processes. There is a growing need for alternative cost-effective methods to harness their potential. This study explored the feasibility of employing waste beverages as feedstock for the counterpart component of a TiO-based composite photocatalyst.

Feeble Single-Atom Pd Catalysts for H Production from Formic Acid.

Single-atom catalysts are thought to be the pinnacle of catalysis. However, for many reactions, their suitability has yet to be unequivocally proven. Here, we demonstrate why single Pd atoms (Pd) are not catalytically ideal for generating H from formic acid as a H carrier.

NTRK2 expression in gastrointestinal stromal tumors with a special emphasis on the clinicopathological and prognostic impacts.

Gastrointestinal stromal tumors (GISTs) are typically characterized by activating mutations of the KIT proto-oncogene receptor tyrosine kinase (KIT) or platelet-derived growth factor receptor alpha (PDGFRA). Recently, the neurotrophic tyrosine receptor kinase (NTRK) fusion was reported in a small subset of wild-type GIST. We examined trk IHC and NTRK gene expressions in GIST.

Mosquitoes Possess Specialized Cuticular Proteins That Are Evolutionarily Related to the Elastic Protein Resilin.

Resilin is an elastic protein that is vital to insects' vigorous movement. Canonical resilin proteins possess the R&R Consensus, a chitin-binding domain conserved in a family of cuticular proteins, and highly repetitive sequences conferring elastic properties. In the malaria vector mosquito, , however, a cuticular protein has been found that has an R&R Consensus resembling that of resilin but lacks the repetitive sequences (here, we call it resilin-related or resilin-r).

Focal ictal direct current shifts by a time constant of 2 seconds were clinically useful for resective epilepsy surgery.

Objective: Ictal direct current shifts (icDCs) and ictal high-frequency oscillations (icHFOs) have been reported as surrogate markers for better surgical outcomes in epilepsy surgery. icDCs have been classified into two types: rapid and slow development. icDCs have been investigated with a time constant of 10 s (TC10s); however, many institutes use electroencephalography with a time constant of 2 s (TC2s).

Serum anti-PCK1 antibody levels are a prognostic factor for patients with diabetes mellitus.

Background: Autoantibodies develop in autoimmune diseases, cancer, diabetes mellitus (DM), and atherosclerosis-related diseases. However, autoantibody biomarkers have not been successfully examined for diagnosis and therapy.

Methods: Serological identification of antigens through recombinant cDNA expression cloning (SEREX) was used for primary screening of antigens.
