Abstract: OBJECTIVE: To explore the effects of exercise and Danzhi Jiangtang Capsule (DJC), a compound traditional herbal medicine, on the JNK signaling pathway in pancreatic tissues of diabetic rats and to investigate the possible mechanisms of exercise and DJC in treating diabetes. METHODS: Seventy-eight male Wistar rats were injected with low dose of streptozotocin and fed a high-fat diet to establish a diabetic model in rats. Then 60 diabetic rats were divided into diabetes group, exercise group, DJC group and exercise combined with DJC group. Another twelve rats were used as normal control. After eight months of treatment, the expression levels of phosphor-c-Jun N-terminal kinase (p-JNK), pancreatic and duodenal homeobox-1 (PDX-1), and insulin protein in pancreatic tissues from rats were detected by immunohistochemical method and Western blotting. RESULTS: In pancreatic tissues of diabetes group, the expression level of p-JNK protein was significantly higher than that in the normal group (P<0.01), and the expression levels of PDX-1 and insulin protein were significantly decreased (P<0.01). After administration of exercise and DJC, the expression level of p-JNK protein in pancreatic tissues of the diabetes group was decreased significantly, while the expression levels of PDX-1 and insulin protein were increased significantly (P<0.05 or P<0.01). CONCLUSION: Exercise and DJC effectively protect islet β-cell function in diabetic rats, which might be due to a decreased JNK signaling pathway.

Abstract: Using a stable human kidney embryonic cell line HEK-293-M-REV3- in which the REV3 gene expression is suppressed by antisense RNA, we measured cell cycle progression and proliferation in an attempt to valuate the roles of REV3 in mutagenesis and tumorigenesis. HEK-293-M-REV3- cells were untreated or treated with DNA damaging agent UVB irradiation or methyl methanesulfonate (MMS), followed by flow cytometry and cell counting to determine the cell cycle distribution and proliferation index (PI). This study revealed that suppression of REV3 delayed spontaneous S phase pro-gression. When treated with MMS or UVB, HEK-293-M-REV3- cells were arrested at S or G2-M phase of the cell cycle, resulting in an increased PI. In light of our previous report that suppression of REV3 limits spontaneous and DNA dam-age-induced mutagenesis, we speculate that failure in translesion synthesis due to the abolation of DNA Polymerasex may cause frequent replication fork arrest and account for the prolonged cell cycle, which is further manifested by external sources of DNA damage. Furthermore, persistent replication fork arrest may evoke cell death or apoptosis.

Abstract: In this paper, a low-complexity blind channel estimation technique is proposed for long-code MIMO CDMA systems. Simply based on the first-order statistic of the decorrelating matched filter output, the channel parameters can be estimated effectively without training sequences. Computer simulations show that the proposed algorithm offers good estimation behavior for MIMO CDMA systems.
The annular gap model for gamma-ray emission from young and millisecond pulsars

Abstract: Pulsed high energy radiation from pulsars is not yet completely understood. In this paper, we use the 3D self-consistent annular gap model to study light curves for both young and millisecond pulsars observed by the Fermi Gamma-ray Space Telescope. The annular gap can generate high energy emission for short-period pulsars. The annular gap regions are so large that they have enough electric potential drop to accelerate charged particles to produce gamma-ray photons. For young pulsars, the emission region is from the neutron star surface to about half of the light cylinder radius, and the peak emissivity is in the vicinity of the null charge surface. The emission region for the millisecond pulsars is located much lower than that of the young pulsars. The higher energy gamma-ray emission comes from higher altitudes in the magnetosphere. We present the simulated light curves for three young pulsars (the Crab, the Vela, the Geminga) and three millisecond pulsars (PSR J0030+0451, PSR J0218+4232, PSR J0437-3715) using the annular gap model. Our simulations can reproduce the main properties of observed light curves.
