Profound hypotonia in an infant with δ-aminolevulinic acid dehydratase deficient porphyria.

δ-Aminolevulinic acid (ALA) dehydratase (ALAD) deficient porphyria (ADP) is an extremely rare form of porphyria, with only eight documented cases. Herein, we report the second known case of ADP in the Western hemisphere and third case with infantile onset of symptoms. A male neonate presented on day three of life with profound hypotonia, pinpoint pupils, absent deep tendon reflexes, and anemia.

Repeat bleaching of a central Pacific coral reef over the past six decades (1960-2016).

The oceans are warming and coral reefs are bleaching with increased frequency and severity, fueling concerns for their survival through this century. Yet in the central equatorial Pacific, some of the world's most productive reefs regularly experience extreme heat associated with El Niño. Here we use skeletal signatures preserved in long-lived corals on Jarvis Island to evaluate the coral community response to multiple successive heatwaves since 1960.

Changes in coral reef communities across a natural gradient in seawater pH.

Ocean acidification threatens the survival of coral reef ecosystems worldwide. The negative effects of ocean acidification observed in many laboratory experiments have been seen in studies of naturally low-pH reefs, with little evidence to date for adaptation. Recently, we reported initial data suggesting that low-pH coral communities of the Palau Rock Islands appear healthy despite the extreme conditions in which they live.

Radiation therapy following resection of non-small cell bronchogenic carcinoma.

Between 1970 and 1982, 102 patients received postoperative radiotherapy after attempted curative resection of bronchogenic carcinoma at The University of Texas M. D. Anderson Cancer Center.
