The effects of finishing rolling temperature on the microstructure and mechanical properties of a direct quenched and partitioned (DQ&P) steel were investigated by a thermal simulation machine, a field emission scanning electron microscope (FE-SEM), electron backscattering diffraction (EBSD), and a transmission electron microscope (TEM). The results show that the original austenite grain size was refined by 31% as the finishing rolling temperature decreased from 920 °C to 840 °C, leading to the formation of the finest martensite lath at 840 °C. At the same time, the lower finishing rolling temperature resulted in a higher dislocation density, and consequently improved the stability of the retained austenite.

Identification of immune-related eRNAs (ireRNAs) in melanoma can provide novel insights into the mechanisms underlying its genesis and progression, along with potential therapeutic targets.
Aim: To establish an ireRNA-related prognostic signature for melanoma and identify potential drug candidates.
[Expression of α(5) subunit of extrasynaptic GABA(A) receptor in insular-kindled rats].

Article Synopsis
- The study investigates the expression of the α(5) subunit of extrasynaptic GABA(A) receptors in rats with induced insular epilepsy, using various control groups for comparison.
- Results showed no significant difference in the number of hippocampal neurons across groups, but both mRNA levels and protein expression of the α(5) subunit were significantly lower in the kindled group compared to control and sham-operated groups at two different time points.
- The findings suggest that decreased expression of the α(5) subunit in the hippocampus may be linked to the development and progression of insular epilepsy, indicating its potential role in this condition.

Objective: To observed the post-seizure expression level of neuropeptides ghrelin and Nesfatin-1 between the untreated and treated groups in kainic acid-kindling rats and understand the significance of their basic expressions.
Methods: The male S-D rats were divided randomly into NS and VPA groups after seizure. Each group was divided into 7 subgroups of 3 h, 6 h, 12 h, 24 h, 3 d, 7 d and 14 d.
Objective: To investigate the expression of Arc mRNA in insular electrical kindled and single electrical stimulated rats and its significance.
Methods: Male SD rats were divided randomly into kindled group, single electrical stimulated group, sham-operated group and control group. Each group was divided into 2 sub-groups at different time points.
