The goal of this study was to investigate the status of FEN1 in Colorectal cancer (CRC) and determine the potential correlation between FEN1 expression level and clinicopathological parameters in CRC patients.

Expression of FEN1 in CRC tissue on tissue microarray was detected using immunohistochemistry (IHC). The relationship between FEN1 expression status and clinicopathologic characteristics of CRC was analyzed by Chi-square test. The survival data of TCGA Colon Cancer (COAD) were obtained from ucsc xena browser (https//xenabrowser.net/). Patients were separated into higher and lower expression groups by median FEN1 expression. The association with prognosis of CRC patients was determined by Kaplan-Meier survival analysis with Log-rank test.

FEN1expression level and cellular localization had wide variability among different individuals, we classified the staining results into four types both positive in nucleus and cytoplasm, both negative in nucleus and cytoplasm, only positive in nucleus, only positive in cytoplasm. Moreover, FEN1 expression status only correlated with patient's metastasis status, and the patients in NLCL group showed more risk of cancer cell metastasis.

Our results indicate that FEN1 expression level and cellular localization had wide variability in CRC and is not a good biomarker in CRC.

In recent years, the great progress has been made in the preparation, functionalization and biomedical applications of the AuNCs. In this article, the latest research progress and synthesis methods of the AuNCs have been summarized, emphasizing the preparation using the "bottom-up" synthesis strategy. Furthermore, we introduced the in vivo pharmacokinetic performance of the AuNCs. The last part, we exemplified the applications of the AuNCs in biomedicine, including photothermal therapy (PTT), bioimaging, drug delivery and radiotherapy sensitization, which further confirmed the great potential of the AuNCs in tumor treatment.Focal Adhesion Kinase (FAK) is a non-receptor tyrosine kinase involved in the process of cell proliferation, survival, migration, and invasion. It has become a promising therapeutic target for treatment of human metastatic cancers due to its overexpression and/or activation in multiple cancer types. Since FAK is emerging as a potential cancer target because of its overexpression at both the transcriptional and translational level in cancer, different types of FAK inhibitors with diversified scaffolds have been discovered in the past few years. In this review, the progress of recently discovered small molecule FAK inhibitors was summarized. Major efforts have been focused on the rational design and synthesis of small molecule FAK inhibitors, and their structure-activity relationship (SAR) analysis were also discussed. Among them, while type I inhibitors remain as the major focuses, type II inhibitors and novel allosteric FAK inhibitors (type III inhibitors) have been developed to improve both potency and selectivity. Netarsudil Meanwhile, novel strategies, such as targeting FAK using inhibitors of protein-protein interactions were also discovered. Lastly, some insights and perspectives on the future development of FAK inhibitors as anticancer therapeutics have been provided.Organ shortage is one of the major limitations in the field of liver transplantation, which has led to the consideration of extended criteria donors as a way to expand the donor pool. The use of extended criteria donors in cases of high Model for End-Stage Liver Disease scores or urgent recipients could be complicated by increased postoperative mortality. Donors on left ventricular assist devices could be considered extended criteria donors because of the mechanical circulatory support itself and the potential of chronic liver damage due to right ventricular failure, but experiences in the literature are limited. Here, we report the first case of an urgent liver retransplant procured from a left ventricular assist device donor.Hepatic arterial flow may have a profound influence on the regeneration process and intergraft competition in dual graft liver transplant. Here, we report a case of impaired left hepatic arterial flow and left lobe graft atrophy in a dual graft recipient. A 52-year-old male patient with hepatitis C-related liver cirrhosis received the right liver lobe from his daughter together with the left lobe from his brother to get an adequate graft volume (65.1% of standard liver volume). The left lobe graft was orthotopically placed to the recipient's left lobe position. The left hepatic artery of the graft was anastomosed to the common hepatic artery of the recipient, for which the recipient's great saphenous vein was used as an interposition graft. Impaired left hepatic arterial inflow perfusion was observed on postoperative day 7, whereas right hepatic arterial flow and portal and venous flows in both grafts were excellent. The recipient now has a normal life with normal liver function tests. A computed tomography scan taken 1.5 years posttransplant demonstrated complete atrophy of the left graft and compensatory regeneration of the right graft. The left graft atrophy may be directly attributed to left hepatic arterial inflow failure in this case.

Thin endometrium is a common problem encountered in the field of assisted reproductive technology. We explored the effects of platelet-rich fibrin in a thin endometrium rat model.

Twenty Sprague-Dawley rats were randomly divided into 2 groups. For the thin endometrium group, endometria of left uteri were injected with ethanol. For the experimental group, platelet-rich fibrin was sutured onto the left uteri of endometria injected with ethanol. Right uteri were kept as the normal (control) group. Two weeks after platelet-rich fibrin transplant, uteri were sampled for histology, immunohistochemistry, Western blot, and real-time reverse transcription-polymerase chain reaction.

Endometrium thicknesses in normal, thin endometrium, and experimental groups were 632.2 ± 38.28, 434.80 ± 41.37, and 603.0 ± 40.93 μm, respectively. Endometrium thickness in the experi-mental group was significantly increased versus the thin endometrium group (P = .011). Immunohistochemical examination showed that expression levels of cytokeratin 18, vimentin, and leukemia inhibitory factor in the experimental group were significantly higher versus the thin endometrium group (P < .
