BACKGROUND: Accurate determination of intraocular pressure (IOP) is essential for correct management of glaucoma. Goldmann applanation tonometry (GAT) is the gold standard for measuring IOP despite its limitations due to its dependence on corneal properties. With the aim of improving the accuracy of GAT readings, several correction formulas have been developed. OBJECTIVE: The aim of this study was to investigate the accuracy and clinical relevance of five correction equations for GAT...

OBJECTIVE: Voltage-gated inward Ca(2+) currents (ICa) are triggered by cell depolarization and commonly produce transient increases in the cytoplasmic free Ca(2+) concentration. The CaV1.2 distal C-terminus is susceptible to proteolytic cleavage, which yields a truncated CaV1.2 subunit and a cleaved C-terminal fragment (CCt or DCT). Stem cells from the apical papilla (SCAPs) has a capacity for differentiation into the odontoblastic-like cells in vitro and dentin forming in vivo, which makes SCAPs advantages in tissue engineering and regenerative endodontic...

A compact neutron spectrometer, based on a CH foil for the production of recoil protons and CR-39 detection, is being developed for the measurements of the DD-neutron spectrum at the NIF, OMEGA, and Z facilities. As a CR-39 detector will be used in the spectrometer, the principal sources of background are neutron-induced tracks and intrinsic tracks (defects in the CR-39). To reject the background to the required level for measurements of the down-scattered and primary DD-neutron components in the spectrum, the Coincidence Counting Technique (CCT) must be applied to the data...

Human embryonic stem cells can replicate indefinitely while maintaining their undifferentiated state and, therefore, are immortal in culture. This capacity may demand avoidance of any imbalance in protein homeostasis (proteostasis) that would otherwise compromise stem cell identity. Here we show that human pluripotent stem cells exhibit enhanced assembly of the TRiC/CCT complex, a chaperonin that facilitates the folding of 10% of the proteome. We find that ectopic expression of a single subunit (CCT8) is sufficient to increase TRiC/CCT assembly...
