Active control of plasmon coupling simple electrochemical surface oxidation/reduction of Au nanoparticle agglomerates.

Reversible tuning of plasmon coupling of Au nanoparticle (AuNP) agglomerates containing dimers as the main component was achieved electrochemical surface oxidation/reduction of the AuNP surface. The system required no reactant except for water and was almost finished within a unit second, which leads to novel active plasmonic devices.

Prostaglandin E increases the expression of cyclooxygenase-2 in cultured rat microglia.

Prostaglandin E (PGE) plays pivotal roles in controlling microglial activation with the EP receptor, a PGE receptor subtype. Activated microglia are often reported to increase cyclooxygenase (COX)-2 expression, followed by PGE production, but it is unclear whether extracellular PGE is involved in microglial PGE synthesis. In the present study, we report that PGE increases COX-2 protein in microglia.

Laparoscopic repair for primary epigastric hernia containing falciform ligament: A case report and review of literature.

Falciform ligament herniation is a rare type of epigastric hernia. We report a case of a primary epigastric hernia containing a falciform ligament repaired using nonabsorbable barbed suture under laparoscopic surgery. A 74-year-old woman presented with discomfort in the upper abdomen.

A Case of Strangulation Ileus Due to a Low-Grade Appendiceal Mucinous Neoplasm.

BACKGROUND Strangulation ileus is caused by external obstruction to the small bowel, which results in ischemia and loss of bowel peristalsis. Low-grade appendiceal mucinous neoplasm (LAMN) is a low-grade adenocarcinoma that arises in the appendix. LAMN is usually asymptomatic but can present with appendiceal rupture and pseudomyxoma peritonei (PMP).

Microscope Observation of Morphology of Colloidally Dispersed Niobate Nanosheets Combined with Optical Trapping.

Although inorganic nanosheets prepared by exfoliation (delamination) of layered crystals have attracted great attention as 2D nanoparticles, in situ real space observations of exfoliated nanosheets in the colloidally dispersed state have not been conducted. In the present study, colloidally dispersed inorganic nanosheets prepared by exfoliation of layered niobate are directly observed with bright-field optical microscopy, which detects large nanosheets with lateral length larger than several micrometers. The observed nanosheets are not strictly flat but rounded, undulated, or folded in many cases.

[A case of a gastrostomy fistula reopening 21 years after spontaneously closure].

Here we report a rare case of a reopened gastrostomy fistula 21-years after spontaneous closure. A male newborn underwent gastrostomy by laparotomy because of esophageal atresia shortly after birth. The gastrostomy tube was removed at 7 months old because he could consume enough oral nutrition.

Evaluation of the effects of gastrectomy on the development of metabolic bone disease.

Background: Metabolic bone disease after gastrectomy is one of the complications leading to deterioration in quality of life. The exact mechanism of the metabolic bone disease remains unclear. To clarify the cause of metabolic bone disease after gastrectomy, we evaluated the associations between the method of gastrectomy and the development of metabolic bone disease in a rat model.

Effects of rabeprazole on bone metabolic disorders in a gastrectomized rat model.

Proton pump inhibitors (PPIs) are frequently prescribed to patients with gastroesophageal reflux disease; however, the number of bone fractures reportedly increased in these patients. Although PPIs have been shown to inhibit the bone resorption by osteoclasts, the effect of PPIs on skeletal metabolism remains controversial. The aim of the present study was to determine the effect of the PPI rabeprazole on skeletal metabolism using gastrectomized rats.

[Bone metabolic disorder after gastrectomy].

Bone metabolic disorder after gastrectomy is a silent complication, and has potential of severely disturbing quality of life. However, the awareness of this complication is not enough in clinicians. We examined the influence of gastrectomy on bone metabolism using the investigation of clinical cases and experiments with rat surgical models.

Single-incision laparoscopic appendectomy for treating appendicitis in a patient with gastrointestinal malrotation.

Introduction: Intestinal malrotation is a rare congenital anomaly, and acute appendicitis associated with intestinal malrotation is extremely rare. PRESENTATION OF CASE We report a rare case of a 47-year-old Japanese woman diagnosed with barium-related perforated appendicitis associated with intestinal malrotation. We used a transumbilical single-incision laparoscopic approach to resect the appendix, and the procedure was completed successfully without perioperative complications.

[Anesthesia for nephrectomy in a patient suspected of spurious polycythemia].

A 46-year-old man suspected of spurious polycythemia received nephrectomy. Spurious polycythemia patients with high blood pressure as a complication have a high possibility of developing cerebral vascular disease. For its prevention, it is important to decrease blood viscosity by phlebotomy and to perform anticoagulation therapy.
