Calcium-containing crystal deposition diseases represent a group of clinically heterogeneous calcific diseases that are a significant source of morbidity.1 Phosphorylated carboxylic acids are powerful inhibitors of biological crystallization as it relates to those diseases.2 Phosphocitrate (PC), a naturally occurring compound (Chart 1),3 is particularly potent. It has been demonstrated to inhib...
The biological basis for the development of the cerebro-cerebellar structures required for posture and gait in humans is poorly understood. We investigated a large consanguineous family from Turkey exhibiting an extremely rare phenotype associated with quadrupedal locomotion, mental retardation, and cerebro-cerebellar hypoplasia, linked to a 7.1-Mb region of homozygosity on chromosome 17p13.1-1...
Newly-formed nanometer-sized particles have been observed at coastal and marine environments world wide. Organic species have so far not been detected in those newly-formed nucleation mode particles. In this study, we applied the ultrafine organic tandem differential mobility analyzer method to study the possible existence of an organic fraction in recently formed coastal nucleation mode partic...
Various types of genomic data (e.g., SNPs and mRNA transcripts) have been employed to identify risk genes for complex diseases. However, the analysis of these data has largely been performed in isolation. Combining these multiple data for integrative analysis can take advantage of complementary information and thus can have higher power to identify genes (and/or their functions) that would othe...
The structural behavior of a chromate aluminate sodalite, Ca8[Al12O24](CrO4)2, at room pressure and on heating from 463 to 982°C was determined by using in situ synchrotron X-ray powder-diffraction data [ = 0.91997(4) Å] and Rietveld refinements. The sample was heated at a rate of about 9.5°C/min., and X-ray traces were collected at intervals of about 17°C. The structure at 463°C is a modulated...
In studies using isolated ovarian granulosa and thecal cells it is important to assess the degree of cross contamination. Marker genes commonly used for granulosa cells include FSHR, CYP19A1 and AMH while CYP17A1 and INSL3 are used for thecal cells. To increase the number of marker genes available we compared expression microarray data from isolated theca interna with that from granulosa cells ...
During slow-wave sleep (SWS) following periods of spatial activity, hippocampal place cells that were temporally correlated, by virtue of the overlap of their place fields, exhibit enhanced temporal correlations, even though the animal sleeps in a different location (Wilson and McNaughton [1994] Science 267:676-679). The discharge of cells with overlapped place fields is more correlated in subs...
