This paper describes an algorithm to improve a computational cost for estimation using the Kriging method with a large number of sampling data. An improved formula to compute the weighting coefficient for Kriging estimation is proposed. The Sherman–Morrison–Woodbury formula is applied to solving an approximated simultaneous equation to determine a weighting(More)
We previously showed the expression of PG-M/versican in embryonic chicken retina. In this study, we characterized the alternatively spliced forms of PG-M/versican and their developmental regulation to investigate the implication of PG-M/versican in neurite outgrowth from retinal cells during development. On day 5, the immunolocalization of PG-M was first(More)
PURPOSE To investigate the chemical toxicity of indocyanine green (ICG). METHODS Surface active and precipitating effects of ICG were quantitatively analyzed by determining bovine serum albumin dissolved or precipitated in the presence or absence of salt solutions. The effects of precipitation on serum and cytotoxicity were evaluated by measuring the(More)
PURPOSE To investigate the two-fold structure of the levator aponeurosis, which is partly composed of independent smooth muscles. MATERIALS AND METHODS Fifteen upper eyelids of 12 Asian postmortems, with age at death ranging from 72 to 91 years, were examined. In 9 eyelids, posterior lamella tissue of the upper eyelid was removed to observe the stratified(More)
PURPOSE To elucidate the microscopic anatomy of the Asian lower eyelid. METHODS Specimens (full-thickness sections of lower eyelids from 19 postmortem lower eyelids) from 11 Asians aged 73 to 96 years at death were fixed in 10% buffered formalin and microscopically examined. After pretreatment, sagittal sliced sections of the central part were stained(More)
PURPOSE To identify microscopically lateral tarsal fixation in Asians. METHODS Specimens from 19 postmortem lateral eyelids and orbits of 11 Asians (11 right, 8 left; aged 45-96 years at death) were used. Samples damaged on sectioning and samples without tarsal plates were excluded. The samples were fixed in 10% buffered formalin and examined under a(More)
PURPOSE To ascertain the cause of undercorrection of the medial palpebral fissure in blepharoptosis surgery. METHODS Twelve upper eyelids of 6 Asian cadavers, 4 male and 2 female (average age at death, 77.5 years), were studied. After exposing the levator muscle by removing bone of the superior orbital rim, the levator muscle and medial and lateral horns(More)
The purpose of this study was to describe the medial horn supporting ligament (MHSL) attached to the medial horn of the levator aponeurosis. The authors examined 3 different groups of specimens: gross cadaveric samples, microscopic cadaveric samples and intraoperative samples from levator resections. In all eyelids in the gross cadaveric samples, the MHSL(More)
This study was performed to elucidate whether the raphe of the orbicularis oculi muscle (raphe) exists or not. Nine upper eyelids of 6 Oriental cadavers with ages at death ranging from 72 to 91 years were dissected; 6 for gross dissections and 3 for histological slice sections. After removing the lateral half of the eyelid skin, the lateral part of the(More)
