REVIEW
Yoshio Misawa
BACKGROUND: Clinical results of ischemic left ventricular free-wall rupture show high mortality rates. METHODS: We reviewed studies published after 1993 on PubMed. RESULTS: A sutureless technique using fibrin glue sheets or patches with/without fibrin glue might contribute to improved clinical results. However, some technique limitations remain for blowout-type ruptures, and the possibility of a pseudoaneurysm formation at the repair site after surgery should be considered...

BACKGROUND: Matrix metalloproteinase 9 (MMP9) has recently emerged as a risk predictor in patients with cardiovascular diseases. However, little is known about the significance of increased plasma MMP9 in patients with perioperative myocardial injury. We aimed to investigate the role of MMP9 in the occurrence of myocardial injury during off-pump coronary artery bypass grafting (OPCAB). METHODS: A total of 34 consecutive patients with coronary artery diseases (CAD) were recruited in this prospective, observational study...

In June 2015, personnel from California's Contra Costa Health Services Environmental Health and Hazardous Materials (hazmat) divisions were alerted to a possible chemical release at a swimming pool in an outdoor municipal water park. Approximately 50 bathers were in the pool when symptoms began; 34 (68%) experienced vomiting, coughing, or eye irritation. Among these persons, 17 (50%) were treated at the scene by Contra Costa's Emergency Medical Services (EMS) and released, and 17 (50%) were transported to local emergency departments; five patients also were evaluated later at an emergency department or by a primary medical provider...

PURPOSE: Pre and post-operative administration of sevoflurane in myocardial revascularization surgery provides enhanced cardioprotective effects exerted by pharmacologic pre- and post-conditioning, as compared to propofol. The identification of the enzymes involved in conditioning mechanisms is crucial to the understanding of the effects of sevoflurane in cardiac surgery patients. The impact of sevoflurane on another crucial target organ-the kidney-was also assessed. METHODS: Ninety patients undergoing off-pump myocardial revascularization surgery were allocated to receive either intra- and postoperative sevoflurane (SS), intraoperative sevoflurane and postoperative propofol (SP), or intra- and postoperative propofol (PP))...

Carbon dot (CD)-NaCl hybrid crystals are obtained by incorporating the CDs into NaCl matrix through a simple process. The embedded CDs have added the luminescence centers into NaCl, and as a result, the hybrid crystals present the fluorescence centered at 510 nm under the illumination of 365 nm light. Meanwhile, the phosphorescence with an average lifetime of 314 ms is achieved after the 365 nm light was turned off. Furthermore, optical gain and lasing phenomenon has been observed from hybrid crystals. When the pump power is low, a weak spontaneous emission can be observed from the hybrid crystal, whereas the lasing action was observed under high pump power...

We have demonstrated a new approach to enhance the uniformity of conversion efficiency in serial-to-parallel data conversion via time lens processing. In our approach, Raman amplification is applied to enhance four-wave mixing in a highly nonlinear fiber. By carefully selecting the pump wavelength, the Raman gain profile can be exploited to compensate the roll-off in conversion efficiency resulted from the varying phase mismatch between the linearly chirped pump and the signal. With Raman amplification, improvement of sensitivity up to 6...

Implantable devices offer an alternative to systemic delivery of drugs for the treatment of neurological disorders. A microfluidic ion pump (µFIP), capable of delivering a drug without the solvent through electrophoresis, is developed. The device is characterized in vitro by delivering γ-amino butyric acid to a target solution, and demonstrates low-voltage operation, high drug-delivery capacity, and high ON/OFF ratio. It is also demonstrated that the device is suitable for cortical delivery in vivo by manipulating the local ion concentration in an animal model and altering neural behavior...

BACKGROUND: We sought to compare the incidence of incomplete revascularization (IR) and long-term survival (up to 20years) after off-pump (OPCAB) versus on-pump (ONCAB) coronary artery bypass in a high OPCAB volume centre where OPCAB was introduced in 1996 and has become the preferred strategy over the years. METHODS AND RESULTS: From 1996 to 2015 a total of 7,427 OPCAB and 7128 ONCAB procedures were performed at Bristol Heart Institute, United Kingdom. We obtained 5423 propensity matched pairs for final comparison...

M Gunkel, E Pawlowsky-Reusing
As part of the project KURAS, the Berliner Wasserbetriebe realized a field campaign in 2015 in order to increase the process knowledge regarding the behaviour of transported sediment in the pressure main leading from the pumpstation to the wastewater treatment plant. The field campaign was conducted because of a lack of knowledge about the general condition of the pressure main due to its bad accessibility and the suspicion of deposits caused by hydraulic underload. The practical evidence of the sediment transport performance of this part of the sewer system, dependent on different load cases, should present a basis for further analysis, for example regarding flushing measures...

Laser cooling and trapping of atoms and atomic ions has led to advances including the observation of exotic phases of matter, the development of precision sensors and state-of-the-art atomic clocks. The same level of control in molecules could also lead to important developments such as controlled chemical reactions and sensitive probes of fundamental theories, but the vibrational and rotational degrees of freedom in molecules pose a challenge for controlling their quantum mechanical states. Here we use quantum-logic spectroscopy, which maps quantum information between two ion species, to prepare and non-destructively detect quantum mechanical states in molecular ions...

Patients with mechanical aortic valves are generally contraindicated for left ventricular assist device (LVAD) insertion because the prosthetic valve often becomes fixed in closed position. A 41-year-old woman with mechanical aortic valve prosthesis experienced sudden chest pain and developed cardiogenic shock. A paracorporeal pulsatile LVAD and a monopivot centrifugal pump as a right VAD (RVAD) were implanted. The mechanical aortic valve was intentionally left in place. Soon after the operation, LVAD support was discontinued daily for few seconds to allow the mechanical aortic valve to open and to avoid thrombus formation...

Lanthanide-doped upconversion nanomaterials are emerging as promising candidates in optoelectronics, volumetric display, anti-counterfeiting as well as biological imaging and therapy. Typical modulations of upconversion through chemical methods, such as controlling phase, composition, morphology and size enable us to rationally manipulate emission profiles and lifetimes of lanthanide ions by using continuous-wave laser excitation. Here we demonstrate that under pulsed laser excitation the emission color of NaYF4:Er/Tm (2/0...
