Cell-free virus is a well-recognized and efficient mechanism for the spread of hepatitis B virus (HBV) infection in the liver. Cell-to-cell transmission (CCT) can be a more efficient means of virus propagation. Despite experimental evidence implying CCT occurs in HBV, its relative impact is uncertain. We develop a 3-D agent-based model where each hepatocyte changes its viral state according to ...

PURPOSE To obtain descriptive statistics of central corneal thickness (CCT) in a large population of normal eyes undergoing refractive surgery and study the relationship of 2 variables, age and refraction, with CCT. SETTING Cornea and Laser Eye Institute, Hersh Vision Group, Teaneck, NJ. METHODS The CCT of 5158 patients was measured using an ultrasound pachymeter. Age and preoperative spher...

PURPOSE To examine the relationship between office-hour changes in IOP, measured with the Goldmann applanation tonometer (GAT) and dynamic contour tonometer (DCT), and the corneal characteristics central corneal thickness (CCT) and corneal hysteresis (CH). METHODS Sixty-two eyes of 62 untreated normal subjects and patients with untreated glaucoma had IOP measurements performed with the GAT (m...

The cornea is a transparent structure that permits the refraction of light into the eye. Evidence from a range of studies indicates that central corneal thickness (CCT) is strongly genetically determined. Support for a genetic component comes from data showing significant variation in CCT between different human ethnic groups. Interestingly, these studies also appear to show that skin pigmentat...

BACKGROUND Central corneal thickness (CCT) is an important indicator of corneal status. Its measurement provides valid information about corneal physiological condition and possible changes associated with diseases, traumas, and hypoxia. It is an integral part for interpretation of intraocular pressure and glaucoma patient management and in prerefractive procedure assessment. OBJECTIVE The ai...

BACKGROUND/AIM To compare the central corneal thickness (CCT) of type II diabetes mellitus patients with age- and sex-matched healthy subjects and to determine the association of the severity of diabetic retinopathy and CCT. MATERIALS AND METHODS Type II diabetes mellitus patients without retinopathy, with nonproliferative retinopathy, and with proliferative retinopathy were organized as the ...

Natural outdoor illumination daily undergoes large changes in its correlated color temperature (CCT), yet existing equations for calculating CCT from chromaticity coordinates span only part of this range. To improve both the gamut and accuracy of these CCT calculations, we use chromaticities calculated from our measurements of nearly 7000 daylight and skylight spectra to test an equation that a...

Critical care transport (CCT) is the segment of the Emergency Medical Services (EMS) system that transports patients who are critically ill or injured. Nearly 1,000 medical helicopters affiliated with over 300 transport programs, hundreds of fixed-wing aircraft, and many, many ground ambulances assisting adult, pediatric and neonatal CCT teams are operating in the United States.1 This article r...

The eukaryotic cytosolic chaperonin containing TCP-1 (CCT) has an important function in maintaining cellular homoeostasis by assisting the folding of many proteins, including the cytoskeletal components actin and tubulin. Yet the nature of the proteins and cellular pathways dependent on CCT function has not been established globally. Here, we use proteomic and genomic approaches to define CCT i...

BACKGROUND Concurrent chemoradiotherapy (CCRT) is the standard treatment for limited-stage small-cell lung cancer (LD-SCLC). However, the efficacy of consolidation chemotherapy (CCT) in LD-SCLC remains controversial despite several studies that were performed in the early years of CCT use. The aim of this study was to reevaluate the effectiveness and toxicities associated with CCT. METHODS Th...
