This article analyzes the religio-ethical discussions of Muslim religious scholars, which took place in Europe specifically in the UK and the Netherlands, on organ donation. After introductory notes on fatwas (Islamic religious guidelines) relevant to biomedical ethics and the socio-political context in which discussions on organ donation took place, the article studies three specific fatwas is...

Background Multi-centre studies generally cost more than single-centre studies because of larger sample sizes and the need for multiple ethical approvals. Multi-centre studies include clinical trials, clinical quality registries, observational studies and implementation studies. We examined the costs of two large Australian multi-centre studies in obtaining ethical and site-specific approvals. ...

Seeking ethics committee approval for research can be challenging even for relatively simple studies occurring in single settings. Complicating factors such as multicentre studies and/or contentious research issues can challenge review processes, and conducting such studies internationally adds a further layer of complexity. This paper draws on the experiences of the LINNAEUS Collaboration, an ...

The relation between tritium content of individual cells and grain count obtained in autoradiographs of squashed cells was investigated. The tissues used were root meristems of Tradescantia paludosa and intestinal epithelium of the mouse. The relation between grain count and tritium content is affected by self-absorption which depends on the thickness of the labeled cell. Therefore, squashed pr...

BaMnF4 microsheets have been prepared using a hydrothermal method. Strong room-temperature blue-violet photoluminescence has been observed (an absolute luminescence quantum yield of 67%) with two peaks located at 385 nm and 410 nm. More interestingly, photon self-absorption phenomenon has been observed, leading to an unusual abrupt decrease in the luminescence intensity at a wavelength of 400 n...

Legacy is defined as something handed down from the past, as from an ancestor or predecessor. The legacy of a great scientist includes not only their seminal work, but also the people they have mentored and inspired. Immunologist William Erwin Paul, who died on September 18 of this year, left just such a legacy. Bill Paul, as everyone knew him, was an extraordinary scientist, administrator, and...

We introduce the concept of Cavity Enhanced Self-Absorption Spectroscopy (CESAS), a new sensitive diagnostic tool for analyzing light-emitting samples. The technique works without an additional light source and its implementation is straight forward. In CESAS, a sample (plasma, flame, or combustion source) is located in an optically stable cavity consisting of two high reflectivity mirrors, and...
