Green route for ammonium nitrate synthesis: fertilizer for plant growth enhancement.

Soil fertility management is of great importance for farmers. The use of synthetic nitrogen (N)-fertilizer increased by 20 fold in the last 50 years to feed the increasingly hungry population. This study aims to enrich the plant soil with nitrogen content (NHNO fertilizer in soil) using the low-temperature and low-pressure plasma [without H and catalyst].

Novel Approach Through the Harmonized Sulfur in Disordered Carbon Structure for High-Efficiency Sodium-Ion Exchange.

Sodium-ion batteries (SiBs) have recently attracted considerable interest due to the plentiful supply of raw materials for their production and their electrochemical behavior, which is similar to that of lithium-ion batteries (LiBs). However, the relatively larger radius of sodium ions than that of lithium ions is not suitable for storage in conventional graphite, which is widely used as the anode. To resolve this issue, in this study, we developed a new harmonized carbon material with a three-dimensional (3D) grapevine-like structure and a sulfur component using an efficient synthesis process.

Efficacy and safety of hangeshashinto for treatment of GERD refractory to proton pump inhibitors : Usual dose proton pump inhibitors plus hangeshashinto versus double-dose proton pump inhibitors: randomized, multicenter open label exploratory study.

Background: Proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease (GERD) leads to a clinical decline in the quality of life (QOL). Therefore, new treatment options are needed. We performed a multicenter, randomized, parallel-group exploratory trial to determine the efficacy of hangeshashinto (HST) in patients with PPI-refractory GERD.

Effect of cationic lipid in cationic liposomes on siRNA delivery into the lung by intravenous injection of cationic lipoplex.

Cationic liposomes composed of dialkyl cationic lipid such as 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP) can efficiently deliver siRNA to the lungs following the intravenous injection of cationic liposome/siRNA complexes (lipoplexes). In this study, we examined the effect of cationic lipid of cationic liposomes on siRNA delivery to the lungs after intravenous injection. We used six kinds of cationic cholesterol derivatives and 11 kinds of dialkyl or trialkyl cationic lipids as cationic lipids, and prepared 17 kinds of cationic liposomes composed of a cationic lipid and 1,2-dioleoyl-L-α-glycero-3-phosphatidylethanolamine (DOPE) for evaluation of siRNA biodistribution and in vivo gene silencing effects.

Small interfering RNA delivery into the liver by cationic cholesterol derivative-based liposomes.

Purpose: Previously, we reported that the cationic liposomes composed of a cationic cholesterol derivative, cholesteryl (2-((2-hydroxyethyl)amino)ethyl)carbamate (OH-C-Chol) and 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE) (termed LP-C), could deliver small interfering RNAs (siRNAs) with high transfection efficiency into tumor cells. In this study, to develop a liposomal vector for siRNA delivery in vivo, we prepared the poly(ethyleneglycol) (PEG)-modified cationic liposomes (LP-C-PEG) and evaluated their transfection efficiency in vitro and in vivo.

Materials And Methods: We prepared LP-C-PEG/siRNA complexes (LP-C-PEG lipoplexes) formed in water or 50 mM NaCl solution, and evaluated their siRNA biodistribution and gene silencing effect in mice after intravenous injection.

Characteristics of refractory gastroesophageal reflux disease (GERD) symptoms -is switching proton pump inhibitors based on the patient's CYP2C19 genotype an effective management strategy?

Objective: We investigated factors related to proton pump inhibitor (PPI) -refractory gastroesophageal reflux disease (GERD) symptoms, particularly with respect to acid, the CYP2C19 genotype and psychological aspects.

Methods: Patients with an Frequency Scale for the Symptoms of GERD (FSSG) score of ≥8 after the initial treatment were switched to therapy with rabeprazole at a dose of 20 mg once daily for eight weeks. We investigated the rate of improvement in PPI-refractory GERD symptoms, background factors, the Hospital Anxiety and Depression Scale (HADS) score and the CYP2C19 genotype.

Strategies for peptic ulcer healing after 1 week proton pump inhibitor-based triple Helicobacter pylori eradication therapy in Japanese patients: differences of gastric ulcers and duodenal ulcers.

Helicobacter pylori (H. pylori) eradication therapy alone is insufficient to ensure healing of large ulcers with H. pylori-positive gastric ulcer (GU).

Utility and problems of endoscopic submucosal dissection for early gastric cancer in elderly patients.

Background And Aim: Endoscopic submucosal dissection (ESD) is reported to be a safe and reliable procedure for the elderly, but these reports could have already had a bias at the time ESD was performed. However, the reports have not clearly stated the criteria of indications. In the present study, we retrospectively elucidated the usefulness and problems of ESD for early gastric cancer in elderly patients (≥ 65 years) in comparison with non-elderly patients.

Gastric ulcer healing after treatment of endoscopic submucosal dissection in Japanese: comparison of H(2) receptor antagonist and proton pump inhibitor administration.

Endoscopic submucosal dissection has made it possible to resect large lesions during a single operation. The present study was undertaken to compare the time taken for recovery from artificial ulcers after endoscopic submucosal dissection between an H(2) Receptor Antagonist treatment group and a Proton Pump Inhibitor treatment group, focusing on analysis of the time course of reduction rate in ulcer area. The powerful acid suppression by Proton Pump Inhibitor may not be needed to treat Japanese post-endoscopic submucosal dissection ulcer which usually develops after early gastric carcinoma in the mucosa of low acid secretory capacity.

Risk management for gastrointestinal endoscopy in elderly patients: questionnaire for patients undergoing gastrointestinal endoscopy.

More elderly patients now undergo gastrointestinal endoscopy following recent advances in endoscopic techniques. In this study, we conducted a high-risk survey of endoscopies in Japan, using a questionnaire administered prior to upper gastrointestinal tract endoscopy (UGITE), and identified anticholinergic agents and glucagon preparations as high-risk premedication. We also evaluated the cardiovascular effects of anticholinergic agents and glucagon through measurements of plasma levels of human atrial natriuretic peptide (hANP) and human brain natriuretic peptide (hBNP).

How closely is Helicobacter pylori infection related to gastroduodenal lesions?

Background/aims: Various studies have indicated a relationship between Helicobacter pylori infection and upper gastrointestinal lesions, but this relationship needs to be assessed in individuals not seeking medical treatment for complaints.

Methodology: We screened community residents for H. pylori infection and upper gastrointestinal lesions during an annual mass health examination aiming to determine relationships between infection and lesions.

Evaluation of gastric motor activity in the elderly by electrogastrography and the (13)C-acetate breath test.

Background: Elderly people frequently have symptoms of fullness and appetite loss due to impaired gastric motor activity. These symptoms may cause malnutrition, immunosuppression and other complications.

Objective: The effects of aging and daily activity on gastric motility in the elderly were investigated by electrogastrography and the (13)C-acetate breath test.
