We investigated the interactions between the cold-water coral Lophelia pertusa and its associated polychaete Eunice norvegica by quantifying carbon (C) and nitrogen (N) budgets of tissue assimilation, food partitioning, calcification and respiration using (13)C and (15)N enriched algae and zooplankton as food sources. During incubations both species were kept either together or in separate cham...

The hypothesis that local changes in extracellular calcium may serve a physiological role in regulating osteoblast, osteoclast, and cartilage function through the extracellular cation-sensing receptor, CasR, is gaining widespread support, but lacks definite proof. To examine the effects of CasR deficiency on the skeleton, we performed a detailed analysis of the skeleton in CasR knockout mice (C...

Since Neuhauser (I1944) drew attention to the radiological features of intra-abdominal calcification associated with meconium peritonitis, this condition has been diagnosed with increasing frequency. However, all cases showing intra-abdominal calcification at birth are not due to meconium peritonitis. Up to the present time four cases have been reported which show calcification within the lumen...

Ocean acidification, as a result of increased atmospheric CO2, is predicted to lower the pH of seawater to between pH 7.6 and 7.8 over the next 100 years. The greatest changes are expected in polar waters. Our research aimed to examine how echinoid larvae are affected by lower pH, and if effects are more pronounced in polar species. We examined the effects of lowered pH on larvae from tropical ...

Abstract Ocean acidification typically reduces the calcification rates of massive Porites spp. corals, but increasing seawater temperatures (below stress and bleaching threshold) can offset this effect. Here, we use δ 11 B to reconstruct pH media (pH ECM ) used precipitate skeleton in poritid corals cultured over a range pCO 2 at 25 °C 28 °C. Increasing temperature had no significant effect on ...

a detailed description of the osteological structure of kiabi loach ( oxynoemacheilus kiabii ), a recently described endemic species caught from gamasiab river, iran, is provided. seven specimens were collected by electrofishing in june 2013 and cleared and stained and its osteological structures were described. the results showed that o. kiabii can be distinguished from other members of the ge...

Extraosseous accumulation of technetium-99m-methyl diphosphonate (99mTc-MDP) on bone scan is not common. This phenomenon is often attributed to abnormality of calcium metabolism and has been reported in a variety of conditions including metabolic diseases and malignancies. A five years old boy is presented here, who was admitted to the pediatric emergency suffering from fatigue, respiratory sym...
