A search was conducted for grains of the potential core-collapse supernova (SN) condensate minerals corundum (Al2O3), hibonite (CaAl12O19), and spinel (MgAl2O4) among grains filtered from the 308.6 m Guliya ice core recovered from the Qinghai-Tibetan plateau in China. Simple models are developed and calculations are presented to estimate the number of Al2O3 grains that would be deposited per cm...

Some geometric inequalities for convex bodies, where the equality cases characterize simplices, are improved in the form of stability estimates. The inequalities all deal with covering by homothetic copies. Mathematics Subject Classification (2000). Primary 52A40, Secondary 52A21.

We show that every upper semicontinuous and equi-affine invariant valuation on the space of d-dimensional convex bodies is a linear combination of affine surface area, volume and the Euler characteristic. 1991 AMS subject classification: Primary 52A20; Secondary 53A15.

Inclusion bodies are insoluble aggregates that are formed by bacteria to store excess recombinant protein produced during expression. The structure of the protein in inclusion bodies is poorly understood but it has been hypothesized that the protein may form misfolded beta sheet aggregates. This paper presents an isotopic labeling and solid-state nuclear magnetic resonance approach to determine...

Nuclei of higher organisms are well structured and have multiple, distinct nuclear compartments or nuclear bodies. Paraspeckles are recently identified mammal-specific nuclear bodies ubiquitously found in most cells cultured in vitro. To investigate the physiological role of paraspeckles, we examined the in vivo expression patterns of two long noncoding RNAs, NEAT1_1 and NEAT1_2, which are esse...

A total of 49 Late Ptolemaic-Roman Period mummies excavated from Kellis-1 cemetery at Ismant el-Kharab in Egypt's Dakhleh Oasis were examined by gross dissection in 1993 and 1998. Of these, 35 were sufficiently intact to reconstruct their mummification methodology. Most of these bodies had been looted at least once in antiquity with consequent damage to their integrity. The bodies of three bund...

BACKGROUND Cytoplasmic inclusion bodies within hepatocytes may have different etiologies, including the Endoplasmic Reticulum Storage Diseases (ERSDs). ERSD is a pathological condition characterized by abnormal accumulation of proteins destined for secretion in the endoplasmic reticulum of hepatocytes; it may be congenital (primary) or acquired (secondary). Fibrinogen storage disease is a form ...
