Physiologically informed organismal climatologies reveal unexpected spatiotemporal trends in temperature.

Body temperature is universally recognized as a dominant driver of biological performance. Although the critical distinction between the temperature of an organism and its surrounding habitat has long been recognized, it remains common practice to assume that trends in air temperature-collected via remote sensing or weather stations-are diagnostic of trends in animal temperature and thus of spatiotemporal patterns of physiological stress and mortality risk. Here, by analysing long-term trends recorded by biomimetic temperature sensors designed to emulate intertidal mussel temperature across the US Pacific Coast, we show that trends in maximal organismal temperature ('organismal climatologies') during aerial exposure can differ substantially from those exhibited by co-located environmental data products.

Long-term, high frequency in situ measurements of intertidal mussel bed temperatures using biomimetic sensors.

At a proximal level, the physiological impacts of global climate change on ectothermic organisms are manifest as changes in body temperatures. Especially for plants and animals exposed to direct solar radiation, body temperatures can be substantially different from air temperatures. We deployed biomimetic sensors that approximate the thermal characteristics of intertidal mussels at 71 sites worldwide, from 1998-present.

Testicular carcinoma presenting as cutaneous nasal metastasis: case report and review of the literature.

Testicular choriocarcinoma is a highly malignant germ cell neoplasm, which metastasises to lungs, and brain. Spread to the skin, however, is rare, with only 11 cases reported to our knowledge. This is the second reported case of a skin metastasis of choriocarcinoma to the head and neck, and the third in which a cutaneous metastasis was the first finding at initial presentation.

[Testicular choriocarcinoma presenting as cutaneous metastasis. A case report and review of the literature].

Choriocarcinoma are germinal tumors from testicular cells in men or foetal trophoblast in women. Cutaneous metastasis are very rare. The authors report a case of angioma-like tumor in a 22-year-old man which was a cutaneous metastasis of a testicular carcinoma.

Tissue and plasma levels of endothelin in free flaps.

The goal of the study was to assess whether endothelin-1 levels are increased in tissue and plasma in free flaps. To assess this hypothesis, blood samples were taken from the general circulation before and after reperfusion and from the flap after reperfusion in 20 patients undergoing breast reconstruction with free transverse rectus abdominis musculocutaneous or deep inferior epigastric perforator flaps. Tissue samples were also taken from the flap before and after the period of ischemia.
