Potassium ferrate (K2FeO4) is an effective oxidant that may be used as a pre- or post-oxidant in the purification of source water with cyanobacterial issues. To provide a better basis for the application of this oxidant during water treatment processes, the impacts of K2FeO4 on the cell viability of Microcystis aeruginosa and the fate of associated microcystins (MCs) were investigated in various water matrices. The results showed that a water matrix can significantly affect the effectiveness of K2FeO4 on cyanobacteria inactivation...

PURPOSE: The aim of the present study was to evaluate whether in a modified natural cycle (modified-NC) for a frozen-thawed single euploid blastocyst transfer, a critical LH value, above which human chorionic gonadotropin (hCG) administration should be avoided, may be defined. METHODS: One hundred and sixty-seven patients underwent modified natural cycle in order to transfer a single frozen-thawed euploid blastocyst. All embryos were obtained by intracytoplasmic sperm injection and were biopsied at the blastocyst stage and analyzed by means of array comparative genomic hybridization (aCGH)...

Cesarean scar pregnancy (CSP) is a rare type of ectopic pregnancy. It is becoming more common, but it can lead to uterine rupture and severe hemorrhage. Here, we report a case of a 37-year-old woman with CSP complicated with pseudoaneurysm. The pseudoaneurysm emerged following focal injection of methotrexate (MTX) and potassium chloride with systemic MTX treatment. Due to a risk of sudden bleeding, uterine artery embolization (UAE) was recommended, but the patient hoped to avoid this if possible. Because the serum human chorionic gonadotropin level and the gestational sac were still persistent, dilation and curettage were performed with interventional radiologists on standby...

PURPOSE: Rupture of the Achilles tendon results in inferior scar tissue formation. Elastography allows a feasible in vivo investigation of biomechanical properties of the Achilles tendon. The purpose of this study is to investigate the biomechanical properties of healed Achilles tendons in the long term. MATERIALS AND METHODS: Patients who suffered from Achilles tendon rupture were recruited for an elastographic evaluation. Unilateral Achilles tendon ruptures were included and scanned in the mid-substance and calcaneal insertion at least 2 years after rupture using shear wave elastography...

Traditionally, the surgical management of acute type B aortic dissections was reserved for patients with signs of malperfusion, rapid expansion, retrograde dissection or rupture. The adjunct of endovascular techniques has brought a paradigm shift, leaning towards preventing long term dissection complications. Multiple risk factors have been proposed to identify patients at risk for long term aortic complications. The patients, who are offered a prophylactic endovascular therapy for uncomplicated aortic dissection, should be selected carefully, and offered intervention by an experienced team in a high-volume center...

Objective: To assess medical economic adequacy of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA). Methods: Cost-utility analysis. A total of 21 patients with AAA treated at Ibaraki Prefectural Central Hospital in 2014 were divided into non-ruptured EVAR (Group E) and open surgery (OS) (Group O), and ruptured OS (Group R) groups, and hospital costs were aggregated with a medical accounting system. Mid-level hospital costs were estimated by a diagnosis-procedure-combination analysis system...

Persistent sciatic artery (PSA) is a rare anomaly that may cause various symptoms, such as aneurysm, rupture, thromboembolism, and sciatica. Direct surgery can be performed to treat PSA aneurysm (PSAA), but is associated with complications; e.g., anatomical problems such as sciatic nerve injury. Herein we report a case of a 74-year-old woman with acute limb ischemia that developed from a distal embolism caused by a thrombus in the left PSAA; favorable results were obtained for her by treatment with a stent-graft after rapid anticoagulation therapy for limb salvage...

Postoperative pseudoaneurysm at the gallbladder fossa is a rare complication of cholecystectomy. The typical clinical presentations of this condition are intraparenchymal or intraperitoneal hemorrhage or rupture into the gastrointestinal tract, and this may be life-threatening. For the treatment of pseudoaneurysms, percutaneous transarterial embolization is considered first-line. We present a case of pseudoaneurysm at the gallbladder following cholecystectomy, which was successfully treated with echo-guided percutaneous transhepatic direct embolization using N-butyl cyanoacrylate, after the failure of transarterial embolization...

Direct carotid cavernous fistulae (CCF) are often detected early and treated promptly resulting in a paucity of literature regarding its long-term evolution. We present a case of high flow post-traumatic direct CCF that was neglected for over 6 years and presented with a rare manifestation of primary intraventricular haemorrhage. Occlusions of the primary venous outlets likely resulted in engorgement of the deep venous system. The segmental anatomy of the shunting basal vein is critical to the clinical presentation and may range from basal ganglia or brainstem oedema/infarctions to uniquely, as in our case, isolated intraventricular haemorrhage secondary to variceal rupture...

During aneurysm clipping, ischemic complications may occur and require a rescue treatment, usually surgical. We present two such cases that required urgent rescue treatment, performed through an endovascular route. Our first case presented with a non-ruptured right posterior inferior cerebellar artery (PICA) aneurysm. After permanent clip positioning, occlusion of the PICA occurred. An unsuccessful attempt of clip repositioning was performed. We therefore positioned a stent obtaining complete flow restoration...

Only a few cases of intraventricular hydatid cysts have been described. The Camalote or waterlily sign is described when there is detachment of the endocyst membrane, resulting in a floating appearance like a waterlily. This sign has been described most commonly in hepatic cysts. Here, we describe the camalote sign in an iatrogenically ruptured intraventricular hydatid cyst. Rupture of an intraventricular hydatid cyst poses the threat of widespread dissemination and is described in our case.

High-pressure processing (HPP) at 250-700 MPa for 30-45 min affects the colour parameters, phytochemical contents and antioxidant activities of purple waxy corn kernels (p < 0.05). The higher pressure-level, the lower L(∗), a(∗), b(∗), C(∗) and h(o) (p < 0.05). However, pressure-treated kernels at 700 MPa showed a similar colour profile to steam-treated kernels. HPP caused a loss in the total phenolic, flavonoid, and anthocyanin contents and antioxidant activities. The pressure-treated kernels had a higher phytochemical content than the steam-treated kernels...

BACKGROUND: An abdominal aortic aneurysm (AAA) is a focal dilation of the abdominal aorta and is associated with a risk of fatal rupture. Experimental studies suggest that myo-inositol may exert beneficial effects on AAAs through favourable changes to biological pathways implicated in AAA pathology. The aim of the Inositol in the MAnaGemENt of abdominal aortic aneurysm (IMAGEN) trial is to assess if myo-inositol will reduce AAA growth. METHODS/DESIGN: IMAGEN is a multi-centre, prospective, parallel-group, randomised, double-blind, placebo-controlled trial...

BACKGROUND: We performed a meta-analysis to assess the presence of a day-of-week rhythmic variability of acute aortic rupture or dissection (AARD) onset. METHODS: Eligible studies were observational studies enrolling patients with AARD and reporting day-of-week variation of AARD. Study-specific estimates, i.e. day-of-week incidence of AARD, were combined using the random-effects model. Chronobiological analysis was performed by applying a partial Fourier series to pooled day-of-week incidence by using the inverse-variance weighted least-squares method...

Forty years have passed since it was first recognized that patients with autoimmune rheumatic disease have an increased risk of fatal and non-fatal cardiovascular (CV) events (1) Although initial reports focused on rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), similar findings were verified subsequently in patients with psoriasis (Ps) and/or psoriatic arthritis (PsA) and spondyloarthritis. An early feature of the atherosclerotic lesion is infiltration with inflammatory cells, particularly monocytes/macrophages, and the presence of these cells in mature plaque elevates the risk of plaque rupture and thrombosis (2)...

Amorphous KNbO3 (KN) film containing KN nanocrystals was grown on TiN/SiO2/Si substrate at 350(o)C. This KN film showed a dielectric constant (εr) and piezoelectric strain constant (d33) of 43 and 80 pm/V at 10 V, respectively, owing to the existence of KN nanocrystals. Piezoelectric nanogenerators (PNGs) were fabricated using KN films grown on the TiN/Polyimide/PET substrates. PNG fabricated with the KN film grown at 350(o)C showed an open-circuit output voltage of 2.5 V and a short-circuit current of 70 nA...

We report the first case of a young patient who presented with the features of Horner's syndrome following a spinal extradural hematoma resulting from a ruptured arterio-venous malformation (AVM). Since there were features of early compressive myelopathy as well, urgent magnetic resonance imaging (MRI) scan of the spine revealed features suggestive of an extradural hematoma in the cervico-thoracic junction. The patient underwent an emergent laminectomy with an evacuation of the hematoma. The histological features were consistent with that of an AVM...

Thromboembolism, one of the leading causes of morbidity and mortality worldwide, is characterized by formation of obstructive intravascular clots (thrombi) and their mechanical breakage (embolization). A novel two-dimensional multi-phase computational model is introduced that describes active interactions between the main components of the clot, including platelets and fibrin, to study the impact of various physiologically relevant blood shear flow conditions on deformation and embolization of a partially obstructive clot with variable permeability...
