[Effects of MD2 gene silencing on high glucose-induced proliferation inhibition, apoptosis and inflammation in rat cardiomyocytes].

Objective: To investigate the effects of myeloid differentiation-2 (MD2) gene silencing on high glucose-induced proliferation inhibition, apoptosis and inflammation in rat cardiomyocytes.

Methods: The immortalized rat cardiomyocyte cell line H9C2 were transfected with MD2 small interfering RNA (si-MD2) and negative control for 24 h, then stimulated with high glucose (HG) for 48 h. RT-qPCR was performed to detect the mRNA levels of MD2 and inflammatory factors TNF-α, IL-1β and IL-6.

Slow cooling and efficient extraction of C-exciton hot carriers in MoS monolayer.

In emerging optoelectronic applications, such as water photolysis, exciton fission and novel photovoltaics involving low-dimensional nanomaterials, hot-carrier relaxation and extraction mechanisms play an indispensable and intriguing role in their photo-electron conversion processes. Two-dimensional transition metal dichalcogenides have attracted much attention in above fields recently; however, insight into the relaxation mechanism of hot electron-hole pairs in the band nesting region denoted as C-excitons, remains elusive. Using MoS monolayers as a model two-dimensional transition metal dichalcogenide system, here we report a slower hot-carrier cooling for C-excitons, in comparison with band-edge excitons.

[The study of the expression and the prognostic value of Survivin and Ki67 in pancreatic endocrine tumors].

Objective: To explore the relationship between the expression of Survivin and Ki67 with prognosis of pancreatic endocrine tumors (PETs).

Methods: Immunohistochemistry for Survivin and Ki67 was performed in 25 cases of normal pancreatic tissues and 81 cases of PETs by tissue microarrays and to observe the expression and evaluate the relationship with prognosis.

Results: (1)The expression of Survivin and Ki67 in PETs was significantly higher than that in normal pancreatic tissues (P <0.

[The effect and mechanism of curcumin derivative B06 on the myocardium from type 2 diabetic rats].

Objective: To investigate the protective effect and mechanism of curcumin derivatives B06 on myocardium from type 2 diabetic rats.

Methods: Thirty-five male SD rats were randomly divided into 5 groups, normal control group (NC group), high fat group (HF group), high fat treatment group (FT group), diabetes mellitus group (DM group) and diabetes treatment group (DT group) (n = 7). The late four groups were fed with high fat food, after four weeks of high fat feeding, the rats from DM group and DT group were injected with low dosage of streptozocin intraperitoneally to induce diabetes mellitus, FT group and DT group were gavaged with curcumin derivatives B06 at the dosage of 0.
