Direct Evaluation of Salivary Antioxidant Properties in Patients with Down Syndrome for assessment to Periodontal Disease and Premature Aging.

To evaluate oxidative stress involved in Down syndrome periodontal disease and pathological premature aging, reactive oxygen species (ROS) such as superoxide (O) and hydroxyl radical (HO) in human saliva were measured using electron spin resonance (ESR) spectroscopy. The groups consisted of 20 subjects in the Down syndrome (DS) child (DC) group (mean age 11.3 ± 4.

Single-Molecule Oxidoreductase Activity Analysis for Activity-Based Diagnosis Based on Proteoform Alterations.

We developed a single-molecule enzyme activity assay platform for NAD(P)-dependent oxidoreductases, leveraging a new NAD(P)H-responsive fluorogenic probe optimized for microdevice-based fluorometric detection. This platform enabled the detection of enzyme activities in blood and cerebrospinal fluid (CSF), including lactate dehydrogenase, glucose-6-phosphate dehydrogenase, and hexokinases. We demonstrate its potential for activity-based diagnosis by detecting altered populations of enzyme activity species in blood and CSF from liver damage in brain tumor patients.

Hemostatic Proximal Anastomosis for Type A Acute Aortic Dissection: Reversed Turn-Up Technique (Akita Method).

In surgery for acute type A aortic dissection, controlling bleeding from the posterior wall of the proximal anastomosis is particularly challenging. To address this, we use the "reversed turn-up technique." For the reinforcement of the proximal aortic stump, Teflon felt strips were placed inside and outside the suture line with 4-0 polypropylene continuous transverse mattress sutures, and BioGlue was applied to the false lumen.

Structural MRI study of Pareidolia and Visual Hallucinations in Drug-Naïve Parkinson's disease.

Visual hallucinations (VH) and pareidolia, a type of minor hallucination, share common underlying mechanisms. However, the similarities and differences in their brain regions remain poorly understood in Parkinson's disease (PD). A total of 104 drug-naïve PD patients underwent structural MRI and were assessed for pareidolia using the Noise Pareidolia Test (NPT) were enrolled.

Late post-endovascular abdominal aortic repair rupture due solely to type II endoleak without other types of endoleak.

Rupture of abdominal aortic aneurysm (AAA) due to an isolated type II endoleak (TIIEL) is rarely reported, accounting for less than 1% of all TIIELs; typically, rupture associated with TIIEL is accompanied by type I or type III endoleaks. We report a case of ruptured AAA secondary to TIIEL without any other types of endoleaks, occurring late after endovascular abdominal aortic repair (EVAR). A 77-year-old man with a history of EVAR 11 years earlier presented with abdominal pain.

Investigation of a self-powered biosensor using a brush-based triboelectric nanogenerator and an enzymatic reaction.

In recent years, wearable devices have undergone remarkable developments. These can easily help us obtain useful information such as that related to our health. However, most devices require a power supply.

Identification of a pancreatic juice-specific fluorescent probe through 411 probes activated by aminopeptidases/proteases or phosphatases/phosphodiesterases.

Background: This study is a retrospective review aimed to identify pancreatic juice-specific fluorescent probes to visualize pancreatic juice using a library of 381 aminopeptidase/protease-activatable fluorescent probes and 30 phosphatase/phosphodiesterase probes. In 2013, we developed a fluorescence imaging technique using a chymotrypsin probe to visualize pancreatic juice, linked to postoperative pancreatic fistula (POPF). This probe required addition of trypsin to convert pancreatic chymotrypsinogen to chymotrypsin.

γ-Secretase Cleaves Bifunctional Fatty Acid-Conjugated Small Molecules with Amide Bonds in Mammalian Cells.

Connecting two small molecules, such as ligands, fluorophores, or lipids, together via a linker with amide bonds is a widely used strategy to generate synthetic bifunctional molecules for various biological and biomedical applications. Such bifunctional molecules have been used in live-cell experiments under the assumption that they should be stable in cells. However, we recently found that a membrane-targeting bifunctional molecule, composed of a lipopeptide and the small-molecule ligand trimethoprim, referred to as mgcTMP, underwent amide-bond cleavage in mammalian cells.

Evaluation of Difference in Emergency Care Quality by Years of Physician Experience at the Emergency Department.

Objective: To evaluate the effect of emergency medicine training credentials and years of medical experience on various clinical parameters in emergency medicine practice.

Methods: A cross-sectional study was conducted at Juntendo University Nerima Hospital between 1 April 2019 and 31 March 2020. All patients who were transported by ambulance, were examined by emergency physicians, and underwent computed tomography (CT) or magnetic resonance imaging (MRI) in the emergency department were included.

Identification of Patients Who Require Two-Point Blood Sampling for the Peak and Trough Values Rather Than One-Point Blood Sampling for the Trough Value for the Evaluation of AUC of Vancomycin Using Bayesian Estimation.

Objectives: It is recommended to adjust the dose of vancomycin (VCM) with a target area under the concentration-time curve (AUC) of 400-600 μg·h/mL. Factors that affect the deviation between AUCs are estimated from the trough value alone and the trough and peak values using practical AUC-guided therapeutic drug monitoring (PAT) for vancomycin. In this study, factors that affect AUC were evaluated.

Hydrosulphide-methaemoglobin-albumin cluster: a hydrogen sulphide donor.

Methaemoglobin (metHb) possesses inherent characteristics that facilitate reversible binding to hydrogen sulphide. Exogenous hydrogen sulphide supplementation imparts beneficial bioactive effects, including antioxidant and anti-inflammatory; hence, we hypothesized that the metHb-hydrogen sulphide complex could act as a hydrogen sulphide donor for medication. In this study, we prepared a hydrosulphide-metHb-albumin (HS-metHb-albumin) cluster and examined its applicability as a hydrogen sulphide donor in the mice model of hepatic ischemia-reperfusion injury.

Novel Eu-Doped Glasses in the MoO-WO-LaO-BO System: Preparation, Structure and Photoluminescent Properties.

Novel multicomponent glasses with nominal compositions of (50-x)MoO:xWO:25LaO:25BO, x = 0, 10, 20, 30, 40, 50 mol% doped with 3 mol % EuO were prepared using a conventional melt-quenching method. Their structure, thermal behavior and luminescent properties were investigated by Raman spectroscopy, differential thermal analysis and photoluminescence spectroscopy. The optical properties of the glasses were investigated by UV-vis absorption spectroscopy and a determination of the refractive index.

Intracranial atherosclerotic disease mechanism indicates poor outcomes of thrombectomy in acute cerebral infarction with large vessel occlusion: A matched cohort study.

Background: Thrombectomy is a standard treatment for acute large vessel occlusion (LVO); however, its effectiveness in treating LVO related to intracranial atherosclerosis disease (ICAD) remains uncertain. This study aimed to compare thrombectomy outcomes in ICAD-related and embolic LVO, focusing on patients with similar symptom severities upon hospital admission.

Methods: This retrospective study was conducted at Jikei University Hospital and Jikei University Kashiwa Hospital between October 2017 and March 2023.

Antitumor Effect of Oleoyl-siRNA against Pancreatic Cancer Using a Portal Vein Infusion Liver-Metastatic Mouse Model.

In this study, we developed an oleoyl-siRNA conjugate in which oleic acid was conjugated at the 5'-end of the sense strand of the siRNA. Furthermore, we examined the effects of RNAi in a mouse model of pancreatic cancer with liver metastasis. The mouse model of pancreatic cancer with liver metastasis was developed by implanting Sui67Luc human pancreatic cancer cells into the portal veins of mice.

Outcome of transvenous lead extraction in nonagenarians: A single-center retrospective study.

Background: Transvenous lead extraction (TLE) for cardiovascular implantable electronic device (CIED)-related infections has increased. The incidence of TLE in nonagenarians is low, with limited reports outlining the outcomes of this procedure. Therefore, in this study, we aimed to clarify the outcomes of TLE in nonagenarians.

Development of a prediction score for Barrett's esophagus in Japanese health checkup settings.

Background: The incidence of esophageal adenocarcinoma has recently increased in Asia, including Japan. A system to identify individuals at high risk for Barrett's esophagus (BE), a pre-cancerous condition of esophageal adenocarcinoma, among the general population is needed to perform endoscopic surveillance appropriately. We therefore developed risk prediction scores for BE at health checkups in Japan.

Spatiotemporal variations of zooplankton community structure in the oyster (Crassostrea gigas)-macroalgae reef dual ecosystems adjacent to Luanhe River Estuary.

Majority of macrozooplankton have a wider dietary niche breadth and utilize small invertebrates, microzooplankton and mesozooplankton, so effect on primary production might be through trophic cascading effect. To better understand the ecosystem structure of benthic oyster-macroalgae reefs, we analyzed zooplankton community structure before (July 2016) and after (from September 2016 to October 2017) the construction of benthic reefs in the 2 km2 sea ranch area in Xiangyun Cove, Tangshan, China. We identified 57 zooplankton species, including the 12 cnidarian (e.
