STUDY QUESTION: How do nano-vesicles extruded from normal first trimester human placentae affect maternal vascular function? SUMMARY ANSWER: Placental nano-vesicles affect the ability of systemic mesenteric arteries to undergo endothelium- and nitric oxide- (NO-) dependent vasodilation in vivo in pregnant mice. WHAT IS KNOWN ALREADY: Dramatic cardiovascular adaptations occur during human pregnancy, including a substantial decrease in total peripheral resistance in the first trimester...

The rising incidences of infections with multidrug-resistant (MDR) Gram-negative bacteria including Pseudomonas aeruginosa (PA) have gained increasing attention in medicine, but also in the general public and global health politics. The mechanisms underlying opportunistic pathogen-host interactions are unclear, however. To address this, we challenged secondary abiotic IL10(-/-) mice deficient for Toll-like receptor-4 (TLR4(-/-) × IL10(-/-)), the main receptor of the Gram-negative cell wall constituent lipopolysaccharide, with a clinical MDR PA isolate...

An 82-year-old man suffering from lower back pain and dyspnea presented to our institute in a state of shock. Computed tomography showed subtotal occlusion of the descending aorta with massive atherosclerotic calcification. As the proximal portion of the superior mesenteric artery was obstructed, emergency bypass from the right axillary artery to the bilateral external iliac arteries was performed, but the patient died 2 days later. Autopsy revealed that reddish-brown and verrucous masses obstructed the descending aorta, and high-grade thickening of the intima and extensive deposits of calcium in the lumina and medial layer were detected in the descending aorta histologically...

A 73-year-old man underwent emergency endovascular abdominal aneurysm repair (EVAR) for a ruptured infected abdominal aortic aneurysm. Two years after EVAR, he was admitted with a spiking fever and left lower back pain. Computed tomography scan revealed not only recurrent graft infection with psoas abscess but also infection around the orifice of the superior mesenteric artery. Because conservative medical therapy with antibiotics could not control the infection, we performed complete removal of the infected stent graft, debridement of psoas abscess, and in situ replacement of the thoracoabdominal aorta using rifampicin-soaked prosthetic grafts, followed by the omental flap...

BACKGROUND: Oral immunotherapy (OIT) is a promising therapeutic approach to treat food allergic patients. However, there are some concerns regarding its safety and long-term efficacy. The use of non-digestible oligosaccharides might improve OIT efficacy since they are known to directly modulate intestinal epithelial and immune cells in addition to acting as prebiotics. AIM: To investigate whether a diet supplemented with plant-derived fructo-oligosaccharides (FOS) supports the efficacy of OIT in a murine cow's milk allergy model and to elucidate the potential mechanisms involved...

An unusual case of a jejunal mesenteric pseudocyst treated by laparoscopic resection is reported. A 44-year-old woman was admitted to our hospital with intermittent upper abdominal pain and diarrhea. Physical examination revealed slight periumbilical tenderness, and no masses were palpable. Contrast-enhanced computed tomography showed a 4-cm-sized nonenhancing high-density mass with a heterogeneous pattern on a proximal small bowel loop. Based on these findings, a gastrointestinal stromal tumor accompanied by hemorrhagic and cystic change, a mesenteric hematoma, or a desmoid tumor was diagnosed...

The current standard care for acute mesenteric ischemia (AMEI) involves urgent revascularization and resection of the necrotic bowel. Since 2012, we have used an AMEI protocol of our own design, which focused on early treatment and allowed interventional cardiologists to become involved when interventional radiologist was not available. A total of 8 patients were treated, and two interventional cardiologists performed all the stenting procedures. The procedure success rate was 100% in patients with non-calcified lesions (6/8)...

Lactobacilli prevent the early development of allergic diseases in children and experimental asthma in mice. However, the detailed mechanism underlying this action remains unknown. We aimed to explore the activation pathway in the host by Lactobacillus and identify its immunomodulation mechanism in allergic asthma. Continuous administration of 10(7) cfu, but not 10(9) cfu, of L. gasseri for 4 weeks prevented Dermatophagoides pteronyssinus (Der p)-induced airway hypersensitivity and inflammation in a mouse model of allergic asthma...

Shear stress or vasocontriction causes endothelial nitric oxide (NO) release results in the regulation of vascular smooth muscle tone in small resistance arteries. Generation of NO is inhibited by nitric oxide synthase (NOS) inhibitors. In this study, we investigated the effect of residual NO, released even in the presence of NOS inhibitors, on the membrane depolarization and phenylephrine-induced contractions of smooth muscle. For this purpose, we used hydroxocobalamin (HC), an NO scavenger, in the presence of NOS inhibitiors, Nω-nitro- L-arginine (L-NA) or Nω-nitro-L-arginine methyl ester (L-NAME) in mesenteric arteries isolated from rats...

Pectin, a water-soluble dietary fiber, has been found to improve survival in endotoxin shock. However, the underlying mechanism by which pectin exerts its protective effect against endotoxin shock remains unknown. Apart from its prebiotic effects, it has been suggested that pectin directly affects immune cells to regulate inflammatory responses. In this study, we investigated the direct effect of pectin in murine model of endotoxin shock. Citrus pectin solution was administered to male C57BL/6 mice for 10 days...

We examined whether chronic estrogen replacement has an inhibitory effect on stress-induced pressor responses via activation of β2-adrenoceptor (AR) in peripheral arteries of ovariectomized rats. Female Wistar rats aged 9 weeks were ovariectomized. After 4 weeks, pellets containing either 17β-estradiol (E2) or placebo (Pla) were subcutaneously implanted into the rats. After 4 weeks of treatment, the rats underwent cage-switch stress and, in a separate experiment, a subset received an infusion of isoproterenol (ISO), with or without pretreatment with β1-AR blocker, atenolol or β2-AR blocker, butoxamine...

The farnesoid X receptor (FXR) plays an important role in bile acid metabolism, intestinal homeostasis, and intestinal ischemia-reperfusion (I/R) injury. We aimed to clarify the potential effects of FXR on intestinal epithelial cell tolerance to intestinal I/R injury and reveal the underlying mechanisms. An intestinal I/R injury model was established by the occlusion of the superior mesenteric artery for ischemia for 1 h, followed by reperfusion for 4 h in C57BL/6 (wild-type; WT)and FXR mice. The small intestine injury was assessed by histological analysis...

Mesenteric cysts are rare, benign gastrointestinal cystic lesions, which are often non-troublesome and present as an incidental radiological finding. However, surgery is often performed in the acute setting to remove lesions that are symptomatic. This report highlights the case of a large, symptomatic mesenteric cyst managed successfully with initial conservative measures followed by planned elective surgery. A 44-year-old female presented with a four-day history of generalised abdominal pain associated with distension, fever, diarrhoea and vomiting...

In a Richter's hernia, only part of the anti-mesenteric border of the bowel is incarcerated within the underlying defect. We report three cases presenting between 18 days and 11 years following proctectomy. As all patients had functioning stomas a high index of suspicion is necessary to avoid a delay in diagnosis.

We report a case of liver abscess and portal vein thrombosis, which occurred due to diverticulitis at the terminal ileum in a 59-year-old man. The patient underwent a barium fluoroscopic examination 1 month before presenting to our hospital. He also showed liver dysfunction due to thrombosis at the superior mesenteric and portal veins. His inflammation gradually subsided after the initiation of treatment, but the recovery was not sufficient. Thus, surgery was performed. The patient condition improved after surgery and he was discharged...
