A thermal nanomotor is relatively easy to fabricate and regulate as it contains just a few or even no accessory devices. Since the double-wall carbon nanotube (CNT)-based rotary nanomotor was established in a thermostat, assessment of the rotation of the rotor (inner tube) in the stator (outer tube) of the nanomotor has been critical, but remains challenging due to two factors: the small size o...

Since the first article introducing doubleballoon endoscopy (DBE) was published in 2001 [1], the technique has proven effective for deep intubation of the small bowel and is used in clinical practice worldwide. However, the intubation depth is sometimes limited by the distension of the small bowel due to air insufflation during the procedure. In a recent report [2], the total success rate using...

If an air flow is injected into a liquid fluid, many ambulant air bubbles are formed inside the fluid. Air bubbles move inside the liquid fluid because of the buoyancy force, and the mobility of these air bubbles makes sizable commixture and turbulence inside the fluid. This mechanism was employed to enhance the heat transfer rate of a horizontal double pipe heat exchanger in this paper. Howeve...

Bacterial resistance to antibiotics is a leading and highly prevalent problem in the treatment of infectious diseases. Bacteriophages (phages) appear to be effective and safe alternatives for the treatment of resistant infections because of their specificity for bacterial species and lack of infectivity in eukaryotic cells. The present study aimed to isolate bacteriophages against Klebsiella sp...

As the population ages, the number of patients in whom lung disease develops and who require surgical intervention will continue to rise. When compared with open thoracotomy, video-assisted thoracoscopic surgery (VATS) offers patients significant advantages. Decreased invasiveness results in less blood loss, a lower rate of infection, and less postoperative pain and allows for quicker recovery....

OBJECTIVE The objective of this study was to evaluate whether the use of a video double-lumen tube reduced the need for fiberoptic bronchoscopy for (1) verification of initial tube placement and for (2) reverification of correct placement after repositioning for thoracotomy. DESIGN A single-center retrospective study. SETTING Thoracic surgery in a medical university hospital. PARTICIPANTS...

Background. The role of multivisceral resection, in the setting of locally advanced gastric cancer, is still debated. Previous studies have reported a higher risk for perioperative morbidity and mortality, with limited objective benefit in terms of survival. Patient. A male patient, 55 years old, was admitted to the clinic of surgery for surgical treatment of bleeding gastric ulceration. Preope...

A method of anaesthesia for the repair of bronchopleural fistulae is described which involves the use of the Robertshaw double-lumen tube. Our experience with its use on twenty occasions is described, and in eleven of them the method was completely successful. In none of the other nine cases were the difficulties encountered such as to render the technique unsafe. Both from the point of view of...
