Aims. To describe and explore the distribution of ocular biometric parameters of adult cataract patients in rural China. Methods. Three Lifeline Express Hospital Eye-Train missions of Peking University People's Hospital in China were chosen. 3828 adult cataract patients aged 29 to 88 years with axial length (AL) less than 27.0 mm were enrolled. The ocular biometry including visual acuity (VA), ...

The va por press ure of tungs te n was measured by the Langmuir method in the te mpe rature range 2600 to 3100 K using a vac uum microbala nce. Four se ries of data gave concorda nt result s and three of the fo ur seri es gave second and third law heats of s ublimation in exce llent agreeme nt. A va por pressure equ ation representing the data is log P(atm )=45385/T + 7.87 1, based on our mean ...

Patients receiving circulatory support with peripheral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) are at risk of developing differential hypoxia. This phenomenon occurs in patients with concomitant respiratory failure. Poorly oxygenated blood, ejected into the ascending aorta from the left ventricle, competes with retrograde flow from the ECMO circuit, potentially causing myoca...
