Direct measurement of hydrogen diffusivity and solubility limits in Zircaloy 2 (formula unit of ZrH) using incoherent quasi-elastic neutron scattering.

The diffusivity of hydrogen is an important property of light water nuclear reactor (LWR) fuel cladding. LWR cladding absorbs hydrogen during normal operation, a contributing factor to embrittlement that decreases the lifetime of the fuel. Mass transport of hydrogen is dictated by an Arrhenius behavior typical of solid state diffusion and the associated activation energy is therefore a property relevant to LWR fuel performance.

Danhong Huayu Koufuye combined with metformin attenuated diabetic retinopathy in Zucker diabetic fatty rats.

Aim: To evaluate effects of Danhong Huayu Koufuye (DHK, a Chinese medicinal formulae) alone or combined with metformin on diabetic retinopathy (DR) in Zucker diabetic fatty (ZDF) rats, an animal model of obese type-2 diabetes, and then to investigate the mechanisms.

Methods: ZDF (fa/fa) rats were administered with vehicle (distilled water), metformin, DHK, and DHK plus metformin. Electrophysiological and histological analysis were applied to evaluated effects of DHK alone or combined with metformin on DR.

[Effect of danhong huayu oral liquid combined with insulin on prevention and progression of early diabetic cardiomyopathy in rats].

Objective: To investigate effects of Danhong Huayu Koufuye (DHK), insulin and their combination on diabetic cardiomyopathy (DC) in streptozotocin (STZ, 50 mg/kg, ip)-induced diabetic rats.

Methods: Rats were divided into five groups: normal control, diabetic treated with vehicle, insulin, DHK, and DHK plus insulin. The animals were treated once daily for 15 weeks starting one week after STZ injection.

Protective effects of naringenin eye drops on N-methyl-N-nitrosourea-induced photoreceptor cell death in rats.

Aim: To investigate the effects of naringenin eye drops on N-methyl-N-nitrosourea (MNU)-induced photoreceptor cell death in rats.

Methods: Photoreceptor cell death was induced by single intraperitoneal injection of MNU (60 mg/kg) in rats. Both eyes of all animals were instilled with one drop of vehicle, 0.

Preventive effect of danhong huayu koufuye on diabetic retinopathy in rats.

Aim: To study the effects of danhong huayu koufuye (DHK) on fasting blood glucose (FBG) and diabetic retinopathy (DR) in streptozotocin (STZ)-induced type 1 diabetic rats to facilitate the rational usage of this drug.

Methods: Diabetic rats were induced by injection of a single dose of STZ intraperitoneally at 50mg/kg. Flash electroretinogram (FERG) and oscillatory potentials (OPs) were used to measure retinal function.
