Three series of experiments on 72 rabbits have shown that lens tumor immunity is not related to the anaerobic nature of its energy metabolism and is not a consequence of lens capsule impermeability for chemical cancer genes. Ionizing radiation causes cataracts without malignancy of lens epithelial
In radiotherapy for eyelid tumors, a sufficient dose is required in the target tissue while preserving the crystalline lens. A I-mm thick, 20-mm diameter lead contact lens was prepared for crystalline lens protection. The lens was coated with an acrylic polymer and weighted 5.5 g. Six MeV electron
BACKGROUND
Colorectal cancer (CRC) is a major global health problem with survival varying according to stage at diagnosis. The incidence of CRC is much higher in patients with lower bowel symptoms. The symptoms are non-specific and are commonly experienced in the general population. Biological and
Determining whether alpha-crystallin (the major lens protein) affects the photophysics of hypericin, a photosensitizing agent found in various plants, such as St. John's Wort, is important. Hypericin shows promise in cancer and human immunodeficiency virus therapy but may harm individuals taking St.
Of a 61-year-old woman with bilateral high myopia and bilateral juvenile cataract (which had been operated upon over 40 years ago), the blind and painful left eye was removed because of a tumour-like mass protruding from the pupil into the anterior chamber. Histological examination revealed this
1. The indications for removing an intraocular lens (IOL) are: A. Chronic uveitis B. Endothelial corneal dystrophy C. Uncontrollalbe glaucoma D. Metal loop cutting pupillary sphincter E. Gross decentration of IOL (fibrous bands) F. Extraocular dislocation of IOL G. Recurrent severe hyphema H.
Using relatively primitive tools in the 1920s, Otto Warburg demonstrated that tumor cells show an increased dependence on glycolysis to meet their energy needs, regardless of whether they were well-oxygenated or not. High rates of glucose uptake, fueling glycolysis, are now used clinically to
Many Siglecs function as inhibitory receptors on innate and adaptive immune cells and may contribute to the attenuation of immune responses to tumors. Siglec 9 on neutrophils and Siglec 7 on NK cells are prominent examples of inhibitory Siglecs that can potentially dampen anti-tumor immunity. CD169
OBJECTIVE
To compare values of the human lens autofluorescence and back light scatter measurements with the improved Lens Opacities Classification System, LOCS III.
METHODS
We measured autofluorescence and back light scatter of the lens from 122 smoking males aged 57 to 76 years who participated in
OBJECTIVE
To demonstrate a rare complication in contactology.
METHODS
A 26-year-old female had "lost" her hard contact lens in the right eye 2 years previously. Afterwards, new contact lenses were not tolerated. The patient had a slight intermittent epiphora but no further complaints. She consulted
The eye lens is unique among tissues: it is transparent, does not form tumors, and the majority of its cells degrade their organelles, including their cell nuclei. A mystery for over a century, there has been considerable recent progress in elucidating mechanisms of lens fiber cell denucleation
Artificial left-handed metamaterial (LHM) provides a new perspective for microwave hyperthermia. Four flat LHM slab lenses can be used to form a focus-flexible applicator for breast tumour hyperthermia. By adjusting microwave sources behind the four flat LHM lenses, microwaves emitted from the
Background: To assess the functional outcomes after combined iris and intraocular lens (IOL) repair in aniridia patients.
Methods: Retrospective observational study in 59
