Thermodes and Theories
This brief outline reviews some of the important studies done with various types of thermodes employed for heating or cooling loci in the brain and discusses some sources of the findings relevant to our understanding of temperature regulation in mammals
Who knows who we are? Questioning DNA analysis in disaster victim identification
The use of DNA analysis as a mode of identification of disaster victims has become increasingly predominant to other, traditional, methods of identification in recent years. Scientific advances of the technological processes, high-profile use in identification efforts across the globe (such as after 9/11 or in the Asian Tsunami of 2004), and its inclusion in popular media, have led to its popular adoption as one of the primary modes of identification in disaster scenarios, and to the expectation of its use in all cases by the lay public and media. It is increasingly argued to be integral to post-disaster management. However, depending on the circumstances, location, and type of disaster, this technology may not be appropriate, and its use may instead conflict with socio-political and cultural norms and structures of power. Using examples primarily from Cambodia and Iraq this article will explore what these conflicts may be, and in doing so, question the expanding assumption that DNA analysis is a universally appropriate intervention in disaster victim identification. It will argue instead that its use may be a result of a desire for the political and social capital that this highly prestigious technological intervention offers rather than a solely humanitarian intervention on behalf of survivors and the dead
Fertility in female survivors of hodgkin's lymphoma.
Currently, Hodgkin's lymphoma is one of the most curable types of cancer. Patients are often young and so the long-term morbidities of treatment have become of increasing concern. Among these, infertility is one of the most challenging consequences for patients in reproductive age. Premature ovarian failure in premenopausal women is a serious long-term sequel of the toxicity of chemotherapy. The main consequence of this syndrome is infertility, but women also present other symptoms related to estrogen deprivation. Different rates of impaired gonadal function are reported, depending on the patient's age, stage of disease, dose and intensity of chemotherapy and the use of radiation therapy. The most established strategy in female infertility is cryopreservation of embryos after in vitro fertilization. Additionally, the use of oral contraceptives or gonadotropin-releasing hormone analogs (GnRH-a) during treatment is under study. This review will provide a general overview of the main studies conducted to evaluate the infertility rate among female Hodgkin's lymphoma survivors and risk factors associated to treatment, different end-pointg definitions for evaluating fertility and also a brief description of the available strategies for fertility preservation
Continuum removal in H\alpha\ extragalactic measurements
We point out an important source of error in measurements of extragalactic
H-alpha emission and suggest ways to reduce it.
The H-alpha line, used for estimating star formation rates, is commonly
measured by imaging in a narrow band and a wide band, both which include the
line. The image analysis relies on the accurate removal of the underlying
continuum. We discuss in detail the derivation of the emission line's
equivalent width and flux for extragalactic extended sources, and the required
photometric calibrations. We describe commonly used continuum-subtraction
procedures, and discuss the uncertainties that they introduce.
Specifically, we analyse errors introduced by colour effects. We show that
the errors in the measured H-alpha equivalent width induced by colour effects
can lead to underestimates as large as 40% and overestimates as large as 10%,
depending on the underlying galaxy's stellar population and the
continuum-subtraction procedure used. We also show that these errors may lead
to biases in results of surveys, and to the underestimation of the cosmic star
formation rate at low redshifts (the low z points in the Madau plot). We
suggest a method to significantly reduce these errors using a single colour
measurement.Comment: 8 pages, 3 figures, MNRAS in pres
