The Medieval Climate Anomaly (MCA) was the most recent pre-industrial era warm interval of European climate, yet its driving mechanisms remain uncertain. We present here a 947-year-long multidecadal North Atlantic Oscillation (NAO) reconstruction and find a persistent positive NAO during the MCA. Supplementary reconstructions based on climate model results and proxy data indicate a clear shift ...

The effect of acute blood glucose elevations on human outer retinal function was examined. Electrooculograms were recorded as the background light cycled on/off with a 2-min period, eliciting rapid changes in the corneo-retinal standing potential known as the fast-oscillation of the electrooculogram. Recordings were made while subjects fasted and after they consumed 100 g of D-glucose. In all s...

As in the proof of Proposition 1, we denote a permutation that changes the ranks of w and w′ in a firm preference list as ρ : (..., w, ..., w′, ...)→ (..., w′, ..., w, ...) and construct preference profile θ′ ∈ Θ from θ∗ as follows: • firm f ’s preferences are the same as in θ∗: θf = θ∗, • workers w and w′ are exchanged in the preference lists of firms −f : ∀f ′ ∈ −f, we have θf ′ = ρ(θf ′), • ...

INVASION of the inside of the eye by squamous cell carcinoma originating in the limbal epithelium is sufficiently rare to warrant brief notice. Duke-Elder (1938) gives seven references to recorded cases, all in the literature of a generation or more ago. There appears to be no recent report of this condition and Reese (1951) refers briefly to its extreme rarity. Parsons (1904) states that invas...

THE treatment of epibulbar growths depends on several factors of which the extent of involvement of the globe itself is the most important; to some extent the line of treatmentadopted depends not only on the preference ofaparticular surgeon but also on the facilities available. Lamellar keratoplasty has often been employed as a therapeutic measure and we have had some experience of it (Sivasubr...

A elderly male presented with painful loss of vision in the left eye for 20 days expulsion intra-ocular content following a blunt trauma. The best corrected visual acuity was counting fingers close to face (CF-CF). Slit lamp examination revealed ciliary tissue prolapse gaping incision scar along posterior synechia, iris pigments, vitreous Anterior chamber, cells and flare. Patients aphakic had ...

AIMS To evaluate the efficacy of amniotic membrane transplantation (AMT) for ocular surface reconstruction. METHODS 10 consecutive patients who underwent AMT were included. The indications were: group A, cases with persistent epithelial defect after corneal abscess (n = 1), radiation (n = 1), or chemical burn (n = 3); group B, cases with epithelial defect and severe stromal thinning and impen...
