H2S pretreatment significantly attenuated LPS-induced apoptosis and inflammation by decreasing c-Jun and caspase-3 levels and inhibiting TNF-α and IL-6, respectively. The decrease in these markers was supported by H&E and Nissl staining, which confirmed the anti-necrotic activity of H2S. However, there was no significant improvement in LPS-induced increase in AChE activity. These results indicate that chronic systemic inflammation leads to neurodegeneration and MI and H2S exerts its neuroprotective effect due to its anti-oxidative, anti-inflammatory, and anti-apoptotic potential via modulation of JNK and extrinsic apoptosis pathways.

To show the feasibility of 3D-printed fixation masks for whole brain radiation therapy in a clinical setting and perform a first comparison to an established thermoplastic mask system.

Six patients were irradiated with whole brain radiotherapy using individually 3D-printed masks. Daily image guidance and position correction were performed prior to each irradiation fraction. The vectors of the daily position correction were compared to two collectives of patients, who were irradiated using the standard thermoplastic mask system (one cohort with head masks; one cohort with head and neck masks).

The mean systematic errors in the experimental cohort ranged between 0.59 and 2.10mm which is in a comparable range to the control groups (0.18mm-0.68mm and 0.34mm-2.96mm, respectively). The 3D-printed masks seem to be an alternative to the established thermoplastic mask systems. Nevertheless, further investigation will need to be performed.

The prevailing study showed a reliable and reproducible interfractional positioning accuracy using individually 3D-printed masks for whole brain irradiation in a clinical routine. Further investigations, especially concerning smaller target volumes or other areas of the body, need to be performed before using the system on a larger basis.

Nuclear receptors (NRs) are crucial transcription factors involved in cell proliferation, metabolism and homeostasis. Through the development of novel genomic approaches, unknown NR functions have recently been uncovered. NR networks derived from gene expression profiles revealed that NRs are tightly linked to human disease and that targeting these links could provide new therapeutic options. MicroRNAs (miRNAs) have known functions as transcriptional regulators of NR function.

I attempted to construct an NR-miRNA transcriptional network based on genomic data from human cancer.

I performed comprehensive analysis with genomic data. Correlation, clustering and survival analysis were done to identify the NR and miRNA correlation in cancer.

Correlation analysis of genomic data revealed relationships between the expression levels of several NRs and miRNAs in human cancer. Based on my NR-miRNA correlation data, I found that NR3C1 expression was highly correlated with that of miR-200 in colon cancer. In most cases, miRNAs suppress expression of their target genes. Thus, miRNAs function as negative regulators during transcription. My analysis revealed that the miR-200 expression level is negatively correlated with that of NR3C1, demonstrating that miR-200 is a negative regulator of NR3C1 in colon cancer. It is known that miR-200 is a master regulator of EMT and that NR3C1 has a link with an EMT marker.

Overall, my genomic analysis revealed that the NR3C1 expression level is correlated with that of miR-200 and that this functional relationship might contribute to colon cancer cell survival. Modulating this axis could be a promising target for treating colon cancer patients.

Glabridin (GB), a bio-available phytoestrogen, displays various biological properties such as anti-inflammatory, antibacterial, and antiviral.

To explore the role of GB in the process of atopic dermatitis (AD).

CCK8 was used to detect the therapeutic effect of Glabridin in HaCat and NHEK cell inflammatory models. And evaluated the effect on cell proliferation and cell viability. The expression of TLR4, MyD88, P65 and P50 in HaCat and NHEK cell tissues was detected by qRT-PCR and PCR. At the same time, an AD animal model was constructed, and the cell experiment results were verified by hematoxylin-eosin (HE) and Immunohistochemistry staining (IHC).

Enzyme-linked immunosorbent assay (ELISA) demonstrated that IL-1β, IL-6, and TNF-α upregulated by lipopolysaccharide (LPS) was decreased by treatment with GB. AD progression was further confirmed to be regulated by GB by inhibiting the TLR4/MyD88/NF-κB signaling pathway through real-time PCR and Western blot analyses. An AD-like mouse model demonstrated that GB considerably alleviated epidermal injury, relieve edema, and reduced inflammatory cell infiltration by H&E staining. Sunitinib manufacturer Concurrently, IHC staining exhibited GB to reduce AD progression by impeding TLR4 expression.

GB was observed to decrease the AD progression by suppressing the TLR4/MyD88/NF-κB signaling pathway, which may likely serve as a novel therapeutic drug for AD management.

To examine the relationship between circumferential tumor extent of colorectal cancer (CRC) on CT colonography (CTC) and clinicopathological features including patient prognosis after surgery.

This retrospective study performed at our institution from January 2013 to December 2019 enrolled 195 consecutive patients (110 men, 85 women; mean age, 64.7years) with CRC evaluated by contrast-enhanced CTC before surgery. The circumferential tumor extent rate (CER) was measured by CTC in virtual colon dissection (VCD) mode to examine the relation between the CER and clinicopathological features and patient prognosis.

CER had association with tumor invasion depth (T), nodal involvement (N), distant metastasis (M), and stage. The Kruskal-Wallis tests showed significant difference for T, N and the stage (p < 0.0001, p = 0.0021 and p < 0.0001) and Wilcoxon rank sum test showed significant difference for M (p = 0.0015). According to the log-rank test, there were no significant differences in OS or DFS between patients with high and low CER.
