Placental site trophoblastic tumor (PSTT) is a rare form of gestational trophoblastic neoplasia (GTN). It most commonly occurs after a delivery but may arise after any type of pregnancy. PSTT arises after neoplastic transformation of intermediate trophoblastic cells. The most commonly reported symptoms are abnormal bleeding or amenorrhea. Due to the rarity of this disease, evidence on prognostic factors as well as optimal treatment is limited. While treatment for early-stage disease is usually limited to surgery, multimodal treatment with chemotherapy and surgery may be important for metastatic disease...

The present study aimed to investigate phosphatidylinositol 4,5-bisphosphate 3‑kinase (PI3K)/protein kinase B (AKT) signaling pathway activation in a rat model of migraine. A total of 60 male Sprague‑Dawley rats were randomly divided into three groups: Blank control; suspension control; and migraine model. The model group was subcutaneously injected with a glyceryl trinitrate suspension, using an optimized Tassorelli method to establish a rat model of migraine. The activation status of the PI3K/AKT signaling pathway was assessed via measurement of the phosphorylated (p)‑AKT level...

Post-stroke dysphagia is common, associated with poor outcome and often requires non-oral feeding/fluids. The relationship between route of feeding and outcome, as well as treatment with glyceryl trinitrate (GTN), was studied prospectively. The Efficacy of Nitric Oxide in Stroke (ENOS) trial assessed transdermal GTN (5 mg versus none for 7 days) in 4011 patients with acute stroke and high blood pressure. Feeding route (oral = normal or soft diet; non-oral = nasogastric tube, percutaneous endoscopic gastrostomy tube, parenteral fluids, no fluids) was assessed at baseline and day 7...

Rationale Vascular nitric oxide levels are low in acute stroke and donors such as glyceryl trinitrate have shown promise when administered very early after stroke. Potential mechanisms of action include augmentation of cerebral reperfusion, thrombolysis and thrombectomy, lowering blood pressure, and cytoprotection. Aim To test the safety and efficacy of four days of transdermal glyceryl trinitrate (5 mg/day) versus sham in patients with ultra-acute presumed stroke who are recruited by paramedics prior to hospital presentation...

Gestational trophoblastic neoplasias (GTNs) are a group of pregnancy-related neoplasms, which include chorioadenoma destruens (invasive mole), placental site trophoblastic tumor, and choriocarcinoma. Although the role of F-FDG PET/CT is still undefined in GTN, in selected cases, it can have significant impact on patient management. Here, we present the case of a 29-year-old woman with hydatidiform mole suggestive of GTN 3 months after evacuation. F-FDG PET/CT demonstrated chorioadenoma destruens (invasive mole) and ruled out metastasis in this case...

Background A common characteristic of migraine-inducing substances is that they cause headache and no pain in other areas of the body. Few studies have compared pain mechanisms in the trigeminal and spinal systems and, so far, no major differences have been noted. We compared signalling molecules in the trigeminal and spinothalamic system after infusion of the migraine-provoking substance glyceryltrinitrate. Method A catheter was placed in the femoral vein of rats and one week later glyceryltrinitrate 4 µg/kg/min was infused for 20 min...

AIM: Animal data suggest that ticagrelor but not clopidogrel protects against tissue injury. It is unclear if this effect of ticagrelor is also detectable in humans. We studied the effect of ticagrelor and clopidogrel at standard clinical doses on endothelial dysfunction in an experimental model of forearm vascular ischemia-reperfusion (IR) injury. METHODS: In a randomised, single-blinded trial 24 subjects underwent forearm blood flow (FBF) measurements in response to the endothelium-dependent vasodilator acetylcholine (ACh) and to glyceryltrinitrate (GTN; endothelium-independent) before and after a 20 min forearm ischemia...
