Ghrelin-attenuated cognitive dysfunction in streptozotocin-induced diabetic rats.

Diabetic encephalopathy is clinically characterized by acquired behavior and cognitive dysfunction but its pathogenesis is not clear. This study aimed to explore the pathogenesis of diabetic encephalopathy and the mechanisms of ghrelin to ameliorate cognitive dysfunction in diabetic rats. Thirty-six streptozotocin diabetic rat models were established; 12 weeks later, all the rats were randomly divided into 3 groups [diabetic model group (D), ghrelin treatment group (T1), and ghrelin and D-lys-3-GHRP-6 treatment group (T2)] of 12 each.

[The serological and genetic identification of a CisAB blood sample].

Objective: To verify the DNA sequence of a sample serologically identified as CisAB.

Methods: Forward and reverse group methods were used to determine the blood serological type of that the sample, and PCR-sequence specific primer (PCR-SSP) method was used for genotyping the sample.

Results: Serologically, the forward group test showed that the sample was AB, while the reverse group test showed that the sample had the anti-B and anti-H + + +.

[Preparation and spectral characterization of CdS(y)Te(1-y) thin films].

CdS(y)Te(1-y) (0 < or = y < or = 1) polycrystalline thin films were prepared on glass substrates by co-evaporation of powders of CdTe and CdS. For the characterization of the structure and composition of the CdS(y)Te(1-y) thin films the X-ray diffraction (XRD) and energy-dispersive spectroscopy (EDS) were used. The results indicate that the values of sulfur content y detected and controlled by the quartz wafer detector show good agreement with the EDS results.
