Zirconium (Zr) hydrides threaten the reliability of fuel assembly and have repeatedly induced failures in cladding tubes and pressure vessels. Thus, they attract a broad range of research interests. For example, delayed hydride cracking induced a severe fracture and failure in a Zircaloy-2 pressure tube in 1983, causing the emergency shutdown of the Pickering nuclear reactor.

In this work, we have designed and synthesized the fluorescent probe 1, which showed a highly selective and sensitive response to Cys over Hcy/GSH in the test. Moreover, the color of probe solution has changed dramatically from colorless to pink with the addition of Cys within 10 min. Meanwhile, the fluorescence intensity exhibited perfectly positive correlation with concentration of Cys from 0 to 200 μM, which offered the important condition for quantitative analysis.

Objective To observe the correlations between heat shock protein 84 ( Hsp84)/ Hsp86 and brain aging in senescence accelerated mouse prone 8 (SAMP8) and the regulation effects of acupuncture. Methods Ten senescence accelerated mouse resistant 1 (SAMR1) were recruited as a normal control group. Another 30 SAMP8 mice were divided into the blank control group, the acupuncture group, and the non-acupoint group by random digit table, 10 in each group.

Phosphodiesterase 9 inhibitors (PDE-9Is) showed memory improving effects in many pharmacological deficit models. However, whether BAY 73-6691 (a selective PDE-9I) may attenuate the oxidative stress during the development of AD is still unclear.

Objective: To reveal the transmembrane signal pathway participating in regulating neuron functions of treating Alzheimer's disease (AD) by acupuncture.
Methods: SAMP8 mice was used for AD animal model. The effect of acupuncture method for qi benefiting, blood regulating, health supporting, and root strengthening on the amount and varieties of transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice was detected using HPLC MS/MS proteomics method.

The acupuncture technique of tonifying qi, regulating blood and strengthening the primary source of human life is established on the base of the new pathology of dementia due to dysfunction of sanjiao by Prof. HAN Jing-xian. It is held that Tanzhong (CV 17), Zhongwan (CV 12), Qihai (CV 6), Xuehai (SP 10), Zusanli(ST 36) and Waiguan (TE 5) were the basic points for treatment of dementia.

Objective: To investigate the preventive action of metformin for atherosclerosis (AS) in patients with type 2 diabetes mellitus (T2DM).
Methods: A total of 140 cases with T2DM were assigned to 2 groups taking metformin (n = 75) or not (n = 65). All cases received intensive control of blood glucose, blood pressure and blood lipids for 100 weeks.

Aim Of The Study: To verify therapeutic effects of Gan-fu-kang (GFK), a traditional Chinese medicine compound, in a rat model and to investigate the underlying mechanisms.
Materials And Methods: Liver fibrosis was established by 12 weeks of carbon tetrachloride (CCl(4)) treatment (0.5mg/kg, twice per week) followed by 8 weeks of "recovery" in rats.
The aim of this study was to evaluate the role of GATA4 in hypertrophy and survival functions of CT-1 in the heart, and to apply chemical inhibitor strategies to assess a possible interaction of signaling pathways involved in these processes. Expression of GATA4 was determined at the mRNA expression (polymerase chain reaction, PCR) and protein binding activity (electrophoretic mobility shift assays, EMSAs) levels. Myocardial apoptosis was detected using the in-situ terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) method.

Objective: To investigate the effect of cardiotrophin-1 (CT-1) on the GATA4 expression and related signaling pathways (JAK-STAT3, ERK1/2 and PI3-K) in rat cardiomyocytes.
Methods: Using semi-quantitative RT-PCR and EMSA, we measured the dose and time dependent effects of CT-1 on GATA4 mRNA and binding activity in cultured rat cardiomyocytes. Parthenolide (a STAT inhibitor), U-0126 (an ERK inhibitor) and LY-294002 (a PI3-K inhibitor) alone or in combination were added to the culture medium to assess the role of above signaling pathways in CT-1 mediated effects.
