    Description: The gene responsible for Friedreich's ataxia, a disease characterized by neurodegeneration and cardiomyopathy, has recently been cloned and its product designated frataxin. A gene in Saccharomyces cerevisiae was characterized whose predicted protein product has high sequence similarity to the human frataxin protein. The yeast gene (yeast frataxin homolog, YFH1) encodes a mitochondrial protein involved in iron homeostasis and respiratory function. Human frataxin also was shown to be a mitochondrial protein. Characterizing the mechanism by which YFH1 regulates iron homeostasis in yeast may help to define the pathologic process leading to cell damage in Friedreich's ataxia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Babcock, M -- de Silva, D -- Oaks, R -- Davis-Kaplan, S -- Jiralerspong, S -- Montermini, L -- Pandolfo, M -- Kaplan, J -- DK30534/DK/NIDDK NIH HHS/ -- DK49219/DK/NIDDK NIH HHS/ -- NS34192/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 Jun 13;276(5319):1709-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, School of Medicine, University of Utah, Salt Lake City, UT 84132, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9180083" target="_blank"〉PubMed〈/a〉

    Description: Over the last century humans have altered the export of fluvial materials leading to significant changes in morphology, chemistry, and biology of the coastal ocean. Here we present sedimentary, paleoenvironmental and paleogenetic evidence to show that the Black Sea, a nearly enclosed marine basin, was affected by land use long before the changes of the Industrial Era. Although watershed hydroclimate was spatially and temporally variable over the last ~3000 years, surface salinity dropped systematically in the Black Sea. Sediment loads delivered by Danube River, the main tributary of the Black Sea, significantly increased as land use intensified in the last two millennia, which led to a rapid expansion of its delta. Lastly, proliferation of diatoms and dinoflagellates over the last five to six centuries, when intensive deforestation occurred in Eastern Europe, points to an anthropogenic pulse of river-borne nutrients that radically transformed the food web structure in the Black Sea.

    Description: Biological sounds produced on coral reefs may provide settlement cues to marine larvae. Sound fields are composed of pressure and particle motion, which is the back and forth movement of acoustic particles. Particle motion (i.e., not pressure) is the relevant acoustic stimulus for many, if not most, marine animals. However, there have been no field measurements of reef particle motion. To address this deficiency, both pressure and particle motion were recorded at a range of distances from one Hawaiian coral reef at dawn and mid-morning on three separate days. Sound pressure attenuated with distance from the reef at dawn. Similar trends were apparent for particle velocity but with considerable variability. In general, average sound levels were low and perhaps too faint to be used as an orientation cue except very close to the reef. However, individual transient sounds that exceeded the mean values, sometimes by up to an order of magnitude, might be detectable far from the reef, depending on the hearing abilities of the larva. If sound is not being used as a long-range cue, it might still be useful for habitat selection or other biological activities within a reef.

    Notes: [Auszug] Sir—In a recent Nature Genetics paper, Morral et al. suggested that the ΔF508 mutation, responsible for 70% of the cases of cystic fibrosis (CF), is at least 2,600 generations old. This is far greater than the usually accepted figure of a few hundred generations2. Morral et al. ...

    Notes: [Auszug] UNLIKE LOVE, HERPES is forever, but the question remains what to do about it. Episodic outbreaks of genital herpes lesions caused by herpes simplex virus type 2 (HSV-2) can be treated with acyclovir, a drug that also offers benefits if used pro-phylactically. Unfortunately, widespread treatment ...
