purpose: to present a patient with localized corneal edema due to a small retained fragment of nucleus in the anterior chamber after uncomplicated phacoemulsification. case report: a 74-year-old female subject with history of phacoemulsification in her right eye about 1.5 years ago complained of foreign body sensation, pain and decreased vision in the same eye. visual acuity of that eye had dec...

The role of receptor tyrosine kinases (RTKs) in transmembrane signaling is well established. Recently, ligand-dependent translocation of RTKs to the nucleus has been reported, but the functional importance of this process remains unclear. In this issue, Sardi et al. (2006) provide evidence for direct signaling in the nucleus by an intracellular ErbB4 receptor fragment that is released upon rece...

A series of N,N?-disubstituted selenoureas containing an adamantane fragment have been synthesized in 23–75% yields. Procedures for the isolation and purification aromatic isoselenocyanates improved. The chemical shift C=Se carbon nucleus 13C NMR spectra has refined. found to be promising as inhibitors not only epoxide hydrolase (sEH-H) but also phosphatase domains (sEH-P) human soluble hydrola...

Configurational information entropy (CIE) theory was employed to determine the neutron-skin thickness of neutron-rich calcium isotopes. The nuclear density distributions and fragment cross sections in 350 MeV/u $$^{40-60}$$ Ca + $$^{9}$$ Be projectile fragmentation reactions were calculated using a modified statistical abrasion-ablation model. CIE quantities determined from density, isotopic, m...

in the present research, we want to simulate the fission process of the excited nucleus 207at produced in fusion reaction 19f+188os in the framework of the modified statistical model with considering the effects of projection of spin about the symmetry axis, k, and temperature. in our simulation, we calculate the fission cross section and anisotropy of the fission fragment angular distribution ...

Histone deacetylases (HDACs) are important regulators of gene expression as part of transcriptional corepressor complexes. Here, we demonstrate that caspases can repress the activity of the myocyte enhancer factor (MEF)2C transcription factor by regulating HDAC4 processing. Cleavage of HDAC4 occurs at Asp 289 and disjoins the carboxy-terminal fragment, localized into the cytoplasm, from the ami...
