The conventional hanging drop technique is the most widely used method for embryoid body (EB) formation. However, this method is labor intensive and limited by the difficulty in exchanging the medium. Here, we report a microfluidic chip-based approach for high-throughput formation of EBs. The device consists of microfluidic channels with 6 × 12 opening wells in PDMS supported by a glass substra...

Dengue is an arthropod-borne virus of great public health importance, and control of its mosquito vectors is currently the only available method for prevention. Previous research has suggested that insecticide treated curtains (ITCs) can lower dengue vector infestations in houses. This observational study investigated individual and household-level socio-demographic factors associated with corr...

BACKGROUND The liver hanging maneuver is a useful technique to transect the liver parenchyma in an open approach while lifting it with a tape passed between the anterior surface of the inferior vena cava and the liver parenchyma. The hanging maneuver during laparoscopic liver resection is not routinely utilized. MATERIALS AND METHODS We describe the technique and results of a modified hanging...

2014 Some experimental results on the macroscopic spreading of hanging and sessile drops on smooth surfaces are presented. The results for sessile drops nicely corroborate the main aspects of the spreading theory of de Gennes and Joanny. However, it is shown that one assumption of the theory, namely the retainment of a self-similar shape during spreading, which is approximately true for sessile...

Engrane is a system which is used to prepare and show presentations of radiological images as well as the reports which belong to these images. The presentations with Engrane will be performed by displaying DICOM (digital imaging and communication in medicine) images and an interpretation of the images presented as text. A database is used to manage DICOM-objects like images and reports. Images...

A housewife hanged herself with her left foot on a washstand and her right foot above the floor. The ligature mark encircled once horizontally at the height of the laryngeal prominence (horizontal part), crossed at the front of the neck, rose to the posterior regions of the mandibular angles and extended upward to the preauricular regions (ascending part). Petechial haemorrhage was in the conju...

Achieving a diffuse sound field in a reverberation chamber is crucial for measurements of acoustic quantities such as sound absorption coefficient, scattering coefficient, and sound power level. Toward this aim, diffusing elements such as hanging panels or rotating diffusers are typically installed in the chamber. However, previous research has suggested that hanging panels violate certain theo...

BACKGROUND To investigate the epidemiology of a steep decrease in the incidence of suicide deaths in Australia. METHODS National data on suicide deaths and deliberate self-harm for the period 1994-2007 were obtained from the Australian Institute of Health and Welfare. We calculated attempt and death rates for five major methods and the lethality of these methods. Negative binomial regression ...

Multicellular tumor spheroids are powerful in vitro models to perform preclinical chemosensitivity assays. We compare different methodologies to generate tumor spheroids in terms of resultant spheroid morphology, cellular arrangement and chemosensitivity. We used two cancer cell lines (MCF7 and OVCAR8) to generate spheroids using i) hanging drop array plates; ii) liquid overlay on ultra-low att...
