Mammalian hair, as a key feature related to endothermy, physical protection, and camouflage, has a long geohistorical record that dates back even to the Mesozoic. However, the limited information on the taphonomy of hair hinders the understanding of its evolutionary significance in deep time. To address this, we conducted taphonomic experiments to simulate the transformation process of black hair. The changes in the morphological structure, microscopic characteristics, and chemical composition of hair during the simulated fossilization process were documented by scanning electron microscopy, Fourier transform infrared(FTIR) spectroscopy, and Raman spectroscopy. Our results revealed that damage to the morphology of hair began at a mild temperature(150–175°C), and hair transformed into a fluid-like mass at a relatively high temperature(200°C). In addition, the morphological structure of melanosomes had relatively greater preservation potential than keratins did, and the microscopic features of melanosomes were persistently stable. The Raman and FTIR spectra indicated that the characteristic melanin and keratin peaks changed as the temperature increased. Although the chemical signals were not lost completely, the variations in the characteristic amide bands in the FTIR spectra indicate that the keratins severely degraded at high temperatures(>200°C), whereas the characteristic melanin bands in the Raman spectra suggested that melanin signals were still recognizable, even at high temperatures(>200°C). These results were confirmed by principal component analysis(PCA) and principal component analysis linear discriminant analysis(PCA–LDA). In addition, the Raman signals of all the samples in the simulated experiments were distinguished from the signals of common geological carbonaceous materials(humic acid), which suggested that Raman spectroscopy can be used to detect melanin in fossils.

Explicit exact solution of supersymmetric Toda fields associated with the Lie superalgebra s/（2｜ 1） is constructed. The approach used is a super extension of Leznov-Saveliev algebraic analysis, which is based on a pair of chiral and antichiral Drienfeld-Sokolov systems. Though such approach is well understood for Toda field theories associated with ordinary Lie algebras, its super analogue was only successful in the super Liouville case with the underlying Lie superalgebra osp（1｜2）. The problem lies in that a key step in the construction makes use of the tensor product decom- position of the highest weight representations of the underlying Lie superalgebra, which is not clear until recently. So our construction made in this paper presents a first explicit example of Leznov-Saveliev analysis for super Toda systems associated with underlying Lie superalgebras of the rank higher than 1.

The experimental studies have demonstrated that some statins have an anticancer effect against ovarian cancer in vitro and in vivo, however, the potential molecular mechanism is still unclear. In the present study, high throughput RNA sequencing(RNA-seq) technology was applied to exploring the mRNA changes treated with Simvastatin in the human ovarian cancer SKOV3 cell line. The result of CCK-8 assay shows that Simvastatin inhibits significantly SKOV3 cell viability in a concentration-dependent manner, and cell cycle according to the flow cytometry analysis result shows cell cycle arrest of G1 phase is induced in SKOV3 cells with 10 μg/mL simvastatin added for 24 h. The differential expression genes(DEGs) analysis of RNA-seq data shows that there are a total of 372 DEGs found in the Simvastatin group, of which 150 mRNAs are up-regulated and 222 mRNAs are down-regulated(fold change>2.0, q value < 0.05). Real time reverse transcription-polymerase chain reaction(qRT-PCR) experiment has validated that the expression of KLF2, RHOB and CIDEB is up-regulated while that of DKK1, AMOTL2 and ANKRD1 is down-regulated. The DEGs are enriched in thirteen significant KEGG pathways including cell cycle, DNA replication, apoptosis, etc. This study provides supported useful information about transcriptome profiles of SKOV3 cell treated with simvastatin, and offers an application basis for the further researches on the mechanism of Simvastatin in the treatment of ovarian cancer.
