Long-term renoprotective effect of luseogliflozin in type 2 diabetes patients: CHikushi Anti-diabetes mellitus Trial-Lusefi (CHAT-Lu).

Several sodium-glucose cotransporter 2 (SGLT2) inhibitors are known to have beneficial effects on renal function in patients with type 2 diabetes. However, the long-term effects of luseogliflozin, an SGLT2 inhibitor, remain uncertain in real-world settings. This multicenter, open-label, prospective observational study evaluated the long-term effects of luseogliflozin on renal function in Japanese patients with type 2 diabetes.

Addition of Sacubitril/Valsartan to Mineralocorticoid Receptor Antagonist Therapy in Primary Aldosteronism: Effects on Plasma Aldosterone Concentration and Plasma Renin Activity.

In the pharmacologic treatment of primary aldosteronism (PA), titration of mineralocorticoid receptor antagonist (MRA) dosing is necessary to reverse the renin suppression caused by high aldosterone levels. However, we often encounter cases in which the plasma renin activity (PRA) does not achieve the target level, even with the maximum dose of MRA. In this setting, sacubitril/valsartan, a combination of a neprilysin inhibitor and an angiotensin II type 1 receptor blocker that is approved for use as adjunctive therapy with an MRA, has been reported to inhibit aldosterone secretion both and .

Zn ions improve the fidelity of metal-mediated primer extension while suppressing intrinsic and Mn-induced mutagenic effects by DNA polymerases.

While Mn ions are well-established for reducing the fidelity of DNA polymerases, leading to the misincorporation of nucleotides, our investigation of the effects of metal ions revealed a contrasting role of Zn. Here, we demonstrate that Zn ions enhance the fidelity of DNA polymerases (the 3' → 5' exonuclease-deficient Klenow fragment and Taq DNA polymerase) by suppressing misincorporation during primer extension reactions. Remarkably, Zn ions inhibit both intrinsic misincorporation and Mn-induced misincorporation of nucleotides.

Impact of renal denervation on quality of life (How does renal denervation contribute to improving hypertension treatment affected by poor medication adherence?).

The US Food and Drug Administration has approved renal denervation (RDN) as a new treatment option for hypertension (HT) because it not only has antihypertensive effects but also improves the quality of blood pressure (BP) reduction. RDN is expected to be increasingly used in clinical practice in the future. This review summarizes the impact of RDN on quality of life (QOL).

Rational design of prodrug-type apoB-targeted siRNA for nuclease resistance improvement without compromising gene silencing potency.

Synthetic siRNA molecules without chemical modifications are easily degraded in the body, and 2'-O-modifications are frequently introduced to enhance stability. However, such chemical modifications tend to impact the gene knockdown potency of siRNA negatively. To circumvent this problem, we previously developed a prodrug-type siRNA bearing 2'-O-methyldithiomethyl (MDTM) groups, which can be converted into unmodified siRNA under the reductive environment in cells.

How Do Disaster Relief Nurses in Japan Perceive and Respond to Risks? A Cross-Sectional Study.

This study assessed the risk perceptions among disaster relief nurses (DRNs) in Japan by focusing on 15 risk factors associated with frequent natural disasters and the ongoing coronavirus disease 2019 (COVID-19) pandemic. We conducted a cross-sectional study that targeted DRNs across six prefectures in Japan and explored nurses' perceptions of risks including radiation exposure, volcanic eruptions, and mass infections. The findings indicated a heightened perception of radiation and nuclear-related risks.

Prodrug-Type Phosphotriester Oligonucleotides with Linear Disulfide Promoieties Responsive to Reducing Environment.

Various chemical modifications have been developed to create new antisense oligonucleotides (AONs) for clinical applications. Our previously designed prodrug-type phosphotriester-modified oligonucleotide with cyclic disulfides (cyclic SS PTE ON) can be converted into unmodified ON in an intracellular-mimetic reducing environment. However, the conversion rate of the cyclic SS PTE ON was very low, and the AON with cyclic SS PTE modifications showed much weaker antisense activity than corresponding to the fully phosphorothioate-modified AON.

3-day intervention program for family members of hikikomori sufferers: A pilot randomized controlled trial.

Backgrounds: Hikikomori, pathological social withdrawal, is becoming a crucial mental health issue in Japan and worldwide. We have developed a 3-day family intervention program for hikikomori sufferers based on Mental Health First Aid (MHFA) and Community Reinforcement and Family Training (CRAFT). This study aims to confirm the effectiveness of the 3-day program by a randomized controlled trial.

A Novel Method for Detecting Lanthanum Phosphate Deposition in the Gastroduodenal Mucosa Using Fluorescence Microscopy.

Diagnostic utility of fluorescence microscopy for lanthanum phosphate deposition in the gastrointestinal mucosa has not been reported previously. In this study, we comparatively assessed the light, electron, and fluorescence microscopy features of gastroduodenal lanthanum phosphate deposition in 10 patients with deposits in the stomach and 5 patients with deposits in the duodenum. During light microscopy, lanthanum deposits were observed as dark-brown, needle-shaped, or crystalloid structures and pale red amorphous materials.

Application of electron microscopy in gastroenterology.

Electron microscopy has long been used in research in the fields of life sciences and materials sciences. Transmission and scanning electron microscopy and energy-dispersive X-ray spectroscopy (EDX) analyses have also been performed in the field of gastroenterology. Electron microscopy and EDX enable (1) Observation of ultrastructural differences in esophageal epithelial cells in patients with gastroesophageal reflux and eosinophilic esophagitis; (2) Detection of lanthanum deposition in the stomach and duodenum; (3) Ultrastructural and elemental analyses of enteroliths and bezoars; (4) Detection and characterization of microorganisms in the gastrointestinal tract; (5) Diagnosis of gastrointestinal tumors with neuroendocrine differentiation; and (6) Analysis of gold nanoparticles potentially used in endoscopic photodynamic therapy.

Intravascular Ultrasound Can Be Used to Locate Nerves, but not Confirm Ablation, During Renal Sympathetic Denervation.

Background: No methods exist for confirming nerve ablation in catheter-based renal sympathetic denervation (RDN).

Methods: We investigated the feasibility of using intravascular ultrasound (IVUS) to locate nerves and observe nerve integrity changes during RDN in a pig. To confirm our observations, we used post-RDN histological sections matched anatomically to the IVUS images.

Pseudoaneurysm and Arteriovenous Fistula in the Radial Artery after Cardiac Catheterization: A Case Report.

We report the case of a 71-year-old man who was experiencing a gradually worsening, dull pain and a cold sensation in his right hand. Three months earlier, he underwent a percutaneous coronary intervention for angina pectoris using a transradial approach in his right wrist and developed an arteriovenous fistula (AVF), a complication of percutaneous coronary intervention. Ultrasonography and computed tomography revealed a pseudoaneurysm and an AVF that were reducing the blood flow in his right hand.

Influence of Aib-Containing Amphipathic Helical Chain Length in MAP(Aib)-cRGD as Carrier for siRNA Delivery.

MAP(Aib)-cRGD, which is a conjugate of an α-aminoisobutyric acid (Aib)-containing amphipathic helical peptide [MAP(Aib)] with a α β integrin binding ligand, cRGD, at the C-terminus of the helical peptide, has been developed for siRNA delivery into cells. In this work, we synthesized three peptides containing 19 (PI), 18 (PII), and 17 (PIII) amino acid residues in the helical peptide, which lack Aib, Leu-Aib, and Lys-Leu-Aib residues present in the C-terminus of the helical peptide of the parent MAP(Aib)-cRGD, respectively. MAP(Aib)-cRGD showed the siRNA delivery into cells and the RNAi effect both in the presence and in the absence of serum in reaction media.

Catheter-based ultrasound renal denervation in patients with resistant hypertension: the randomized, controlled REQUIRE trial.

Renal denervation is a promising new non-pharmacological treatment for resistant hypertension. However, there is a lack of data from Asian patients. The REQUIRE trial investigated the blood pressure-lowering efficacy of renal denervation in treated patients with resistant hypertension from Japan and South Korea.

The mental health status of children who have been evacuated or migrated from rural areas in Fukushima prefecture after the Fukushima daiichi nuclear power station accident:results from the Fukushima health management survey.

Introduction: We evaluated the mental health status of children residing in Kawauchi village (Kawauchi), Fukushima Prefecture, after the 2011 accident at the Fukushima Daiichi Nuclear Power Station, based on the children's experience of the nuclear disaster.

Methods: We conducted this cross-sectional study within the framework of the Fukushima Health Management Survey (FHMS);FHMS data on age, sex, exercise habits, sleeping times, experience of the nuclear disaster, and the "Strengths and Difficulties Questionnaire (SDQ)" scores for 156 children from Kawauchi in 2012 were collected. Groups with and without experience of the nuclear disaster - "nuclear disaster (+)" and "nuclear disaster (-)" - were also compared.

Enzymatic formation of consecutive thymine-Hg-thymine base pairs by DNA polymerases.

From the perspective of the preparation of a DNA-based nanowire containing an array of metal ions, DNA-polymerase-catalyzed primer extension reactions were investigated and the formation of up to ten consecutive T-Hg-T base pairs was achieved by the Hg-mediated primer extension reaction in the presence of Mn ions. This enzymatic approach may be one of the promising techniques for preparing a DNA-based metal array.

Survey of awareness of radiation disasters among firefighters in a Japanese prefecture without nuclear power plants.

Japanese firefighting organisations are essentially run as village, town, or city units. The Great Hanshin Earthquake of 1995 led to the establishment of emergency support teams to ensure rapid action in response to disasters beyond the capacities of local fire departments. The 2011 Great East Japan Earthquake involved both a tsunami and a radiation disaster caused by a nuclear reactor meltdown, underscoring the need for responses in complex disasters.

Methods: This study used a multi-center, open-label, prospective observational design. Type 2 diabetes patients who were undergoing dietary therapy and/or exercise therapy alone without sufficient glycemic control (hemoglobin A1c (HbA1c) ≥ 6.

Review of the diagnosis of gastrointestinal lanthanum deposition.

Lanthanum carbonate is used for treatment of hyperphosphatemia mostly in patients with chronic renal failure. Although lanthanum carbonate is safe, recently, lanthanum deposition in the gastrointestinal mucosa of patients has been reported in the literature. This review provides an overview of gastroduodenal lanthanum deposition and focuses on disease's endoscopic, radiological, and histological features, prevalence, and outcome, by reviewing relevant clinical studies, case reports, and basic research findings, to better understand the endoscopic manifestation of gastrointestinal lanthanum deposition.

Elevated chymase-dependent angiotensin II-forming activity in circulating mononuclear leukocytes was observed in the patient of atrial fibrillation.

Chymase is an angiotensin II-forming serine proteinase and elevation of its tissue activity occurs in various cardiovascular diseases. Several authors have suggested that there is an association between the renin-angiotensin system and atrial fibrillation (AF). Chymase-dependent angiotensin II-forming activity in circulating mononuclear leukocytes (CML chymase dAIIFA) was investigated in patients with AF and patients in sinus rhythm.

Preliminary Observations on the Antihypertension Action of Dabigatran Etexilate in Patients With Nonvalvular Atrial Fibrillation: A Prospective Multicenter Single-Arm Interventional Study.

Background: In Japan, the number of patients with atrial fibrillation continues to grow with the aging of the population. Prevention of cardiogenic cerebral embolism is extremely important in patients with atrial fibrillation. While warfarin has long played a major role for this purpose, a new oral anticoagulant, dabigatran etexilate (dabigatran), has demonstrated superior efficacy and safety in recent years.
