Abstract: The disclosure generally describes methods of preventing or treating ophthalmic diseases or conditions in a mammalian subject, such as diabetic retinopathy, cataracts, retinitis pigmentosa, glaucoma, macular degeneration, choroidal neovascularization, retinal degeneration, and oxygen-induced retinopathy. The methods comprise administering an effective amount of an aromatic-cationic peptide to subjects in need thereof.

Abstract: An electric air pump includes a housing, a cover body, an inflation module, and a control module. The housing is provided with a first vent port. The cover body covers the housing, and the cover body is provided with a second vent port. The inflation module is disposed in the housing. The control module is disposed in the housing, and the control module comprises a control circuit board and an air pressure detection unit. The air pressure detection unit is disposed on the control circuit board, and the control circuit board is electrically connected to the inflation module and configured for performing controlling.

Abstract: The present disclosure provides a method for assessing hot coal fallout propensity of burning cigarettes based on human behavior features of ash-tapping action. The method is characterized in that the method is accomplished through an apparatus for detecting hot coal fallout propensity based on human behavior features of ash-tapping action, which include behavior features of human action of tapping cigarette ash, features of holding a cigarette, and features of force applying process and other aspects. This method can provide objective and accurate test basis for evaluation of cigarette fallout performance.

Abstract: The present invention discloses a nitrilase mutant and its construction method and its application in the synthesis of chiral intermediate of pregabalin in the technical field of bioengineering. The present invention, respectively, takes turnip nitrilase BrNIT and arabidopsis nitrilase AtNIT as parent, using peptide fragment displacement method, displaces the sites 226-286 of BrNIT amino acid sequence and sites 225-285 of AtNIT amino acid sequence with sites 225-285 of Arabis alpina L. nitrilase AaNIT, obtain nitrilase mutants BrNIT225-285 and AtNIT225-285 of which the amino acid sequence is as shown in SEQ ID NO.1 or SEQ ID NO.3.

Abstract: Provided are an internal and external dual-purpose air pump, an inflatable product and a lifting handle device; the internal and external dual-purpose air pump includes a machine core, including a housing having an accommodating chamber and an inflating device arranged in the accommodating chamber; the housing is provided with an air outlet and an air suction inlet respectively in the bottom and top ends, and the air outlet and the air suction inlet can both communicate with the accommodating chamber; and the housing is slidably connected with a buckling member, which can move relative to the housing, thereby the machine core is buckled into or detached from a product to be inflated through the buckling member; the inflating device works to send air flow out through the air outlet and/or suction air flow through the air suction inlet. The inflatable product includes the internal and external dual-purpose air pump.

Abstract: The present disclosure provides a method for assessing hot coal fallout propensity of burning cigarettes based on human behavior features of ash-flicking action. The method is characterized in that the method is accomplished through an apparatus for detecting hot coal fallout propensity based on human behavior features of ash-flicking action, which include behavior features of human action of flicking cigarette ash, features of holding a cigarette, and features of force applying process and other aspects. This method can provide objective and accurate test basis for evaluation of cigarette fallout performance.
