Since 1995, video-assisted thoracoscopic oesophagectomy (VATS), according the same surgical principles as the Japanese open surgery, has been completed in 700 patients with oesophageal cancer. Our indication for VATS is (I) no extensive pleural adhesion; (II) no contiguous tumor spread; (III) pulmonary function capable of sustaining single-lung ventilation, and (IV) non radiated patients. We use 4 ports around a 5 cm mini-thoracotomy on 5th intercostal space. We laid emphasis on utilizing magnifying effect of video (5 to 20 magnifications), obtained by positioning the camera at close vicinity to the dissection...

Hysterectomy is one of the most commonly performed gynecologic surgeries, mainly for uterine myomas, abnormal uterine bleeding, and prolapses. It can be performed through several routes, each of which has its advantages and disadvantages. We conducted this systematic review to evaluate recent advances in surgical outcomes of benign total hysterectomies by any route: vaginal (VH), laparoscopic (LH), laparoscopically assisted vaginal (LAVH), single-port (SP), and robotic-assisted laparoscopy (RH). The search was applied to the PubMed electronic database by using keywords "hysterectomy" and "uterine benign disease", "adenomyosis", and "myoma"...

Mitigating black carbon (BC) emissions from various combustion sources has been considered an urgent policy issue to address the challenges of climate change, air pollution and health risks. Vehicles contribute considerably to total anthropogenic BC emissions and urban BC concentrations. Compared with heavy-duty diesel vehicles, there is much larger uncertainty in BC emission factors for light-duty passenger vehicles (LDPVs), in particular for gasoline LDPVs, which warrants further studies. In this study, we employed the dynamometer and the Aethalometer (AE-51) to measure second-by-second BC emissions from eight LDPVs by engine technology and driving cycle...

A photonic radiofrequency (RF) filter with two complementary bandpass and bandstop responses that is capable of simultaneously providing a single transmission channel at one port and a notch rejection channel at the other port is proposed. An integrated polarization division-multiplexing Mach-Zehnder modulator and the in-fiber stimulated Brillouin scattering effect are used to control the amplitudes and phases of the RF modulation sidebands along two orthogonal states of polarization to generate two complementary bandpass and bandstop responses at two output ports, respectively...

Traditionally, arthrocentesis involves insertion of 2 needles into the joint space of which one acts as an inflow port and the other as the outflow port. These 2 needles must triangulate and be exactly placed in the upper joint space for the procedure to be effective. Due to the difficulty in maintaining the needle position, single-puncture arthrocentesis is gaining popularity. It is relatively easier to perform and less traumatic to the joint. The authors describe a simple technique of single-puncture arthrocentesis using parts of 2 peripheral intravenous catheters of different gauges...

The Existing Substances Regulation Risk Assessments by the European Union (EU RA) generated new toxicity data for soil organisms exposed to Ni added to sixteen field-collected soils with low background concentration of metals and varying physico-chemical soil characteristics. Using only effective cation exchange capacity (eCEC) as a bioavailability correction, chronic toxicity of Ni in soils with a wide range of characteristics could be predicted within a factor of two. The objective of the present study was to determine whether this was also the case for three independent data sets of Ni toxicity thresholds...

Robotic-assisted laparoscopic surgery in urology is an ever progressing field, and boundaries are constantly broken with the aid of new technology. Advancements in instrumentation have given birth to the era of robotic laparoendoscopic single-site technique (R-LESS). R-LESS however, has not gained widespread acceptance due to technical hurdles such as adequate triangulation, robotic arm clashing, decreased access for the bedside assistant, lack of wrist articulation, continued need for an axillary/accessory port, lack of robust retraction, and ergonomic discomfort...

From January to June 2013 and November to January 2014, mass mortalities were reported in Pacific oysters Crassostrea gigas cultivated in Port Stephens estuary, New South Wales, Australia. In some cases, 100% mortality was reported in both triploid and diploid C. gigas, although native species of oyster cultivated in the same areas remained unaffected. Histological examination of oysters sampled from the time of mortality events revealed consistent but non-specific pathology, involving a diffuse haemocytic infiltrate in the connective tissue surrounding the digestive gland, extending into the mantle in some instances, but no other signs of any infectious aetiological agent...

In this study, methane-ethylene jet diffusion flames modulated by acoustic excitation in an atmospheric environment were used to investigate the effects of acoustic excitation frequency and mixed fuel on nanomaterial formation. Acoustic output power was maintained at a constant value of 10 W, while the acoustic excitation frequency was varied (f = 0-90 Hz). The results show that the flame could not be stabilized on the port when the ethylene volume concentration (ΩE) was less than 40% at f = 10 Hz, or when ΩE = 0% (i...

BACKGROUND: Laparoscopic local gastric resection has become the standard form of surgery for gastric submucosal tumors (SMTs) and is currently being actively selected for these cases. However, total gastrectomy or proximal gastrectomy is performed when tumors are adjacent to the cardia of stomach. Unfortunately, these procedures are highly invasive and can cause marked decreases in activities of daily living. We perform a single-incision laparoscopic intragastric surgery (sLIGS), which are both minimally invasive and offers improved cosmetic outcomes, to treat SMT located adjacent to the esophagogastric junction (EGJ)...
