A 56 years old male with chronic pancreatitis complained of intractable abdominal pain, anorexia, emaciation and peripheral edema. Medical treatment initiated only partial improvement in the general condition and hypoproteinemia. Endoscopic retrograde cholangiopancreatography revealed multiple filling defects in the dilated main pancreatic duct. Endoscopic aspiration of pure pancreatic juice yi...

BACKGROUND Bronchial thermoplasty (BT) is a new therapeutic option for severe refractory asthma not controlled despite high dose inhaled corticosteroids plus long-acting bronchodilators and omalizumab in selected cases. Risk of pulmonary atelectasis after BT in severe asthma has been described in literature, but no details have been reported on the possible mechanisms of the complication. CAS...

This communication introduces a digital design for tunable microfluidic optical fiber devices. In these systems, multiple, independently controlled microfluidic plugs are pumped into or out of overlap with a fiber structure to modulate its transmission characteristics. The devices described here use eight plugs, eight electrowetting pumps and a corresponding set of molded planar recirculating m...

An experimental study of ignition and combustion a propane/air mixture is carried out, the efficiency two systems compared. The first one traditional technology with conventional spark plugs, second system microwave initiated streamer discharges. In both cases, sources, plugs or discharges are distributed along surface chamber. A subcritical discharge on circular tube using half-wave resonator ...

The purpose of this study is to determine the largest and smallest power values maximum change in BMEP on influence shape spark plug electrode tip a 150 cc motorcycle engine. This applies laboratory experiments as research method with open full-throttle test method. increased for each standard plugs yields highest 6.64 kW at 6000 rpm lowest 2000 2.04 kW. While spherical iridium produces 2.09 rp...

Particle concentration is a key unit operation in biochemical assays. Although there are many techniques for particle concentration in continuous-phase microfluidics, relatively few are available in multiphase (plug-based) microfluidics. Existing approaches generally require external electric or magnetic fields together with charged or magnetized particles. This paper reports a passive techniqu...

BACKGROUND/AIMS To evaluate the safety and efficacy of punctal plugs in children with dry eye syndrome. METHODS A retrospective case series of patients who had an insertion of silicone punctal plugs for dry eye syndrome. Data collected included presenting symptoms, signs, systemic disorders if present, type of anaesthesia and complications by the time of last follow-up. RESULTS Twenty-five ...
