BMI-1 activates hepatic stellate cells to promote the epithelial-mesenchymal transition of colorectal cancer cells.

Background: Activated hepatic stellate cells (aHSCs) are the major source of cancer-associated fibroblasts in the liver. Although the crosstalk between aHSCs and colorectal cancer (CRC) cells supports liver metastasis (LM), the mechanisms are largely unknown.

Aim: To explore the role of BMI-1, a polycomb group protein family member, which is highly expressed in LM, and the interaction between aHSCs and CRC cells in promoting CRC liver metastasis (CRLM).

Offspring mice (n = 176) from both groups were weaned at postnatal day 21, and for 6 months after postnatal day 21, 96 mice were fed either a standard chow diet (n = 48) or a high-fat diet (n = 48).

Preliminary study on fine structures of subcortical nuclei in rhesus monkeys by 9.4 T MRI.

Changes in fine structures of the brain over a life span can have robust effects on neural activity and brain function, which both play crucial roles in neurodegenerative diseases. Clinically, however, low-resolution MRI only provides limited information about fine brain structures. Here, using high-resolution 9.

Microglial activation and neurobiological alterations in experimental autoimmune prostatitis-induced depressive-like behavior in mice.

Background: Patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) frequently show depressive symptoms clinically and increasing evidence indicates a correlation between CP/CPPS and depression. However, the underlying mechanisms of CP/CPPS-related depression remain poorly understood. Here, we sought to determine the role of hippocampal microglial activation and neurobiological changes in a mouse model of experimental autoimmune prostatitis (EAP)-induced depression and the treatment efficacy of Chinese herb extract baicalein.

Tankyrase Promotes Aerobic Glycolysis and Proliferation of Ovarian Cancer through Activation of Wnt/-Catenin Signaling.

Tankyrase (TNKS) plays important roles in the malignancy of several cancers such as human lung tumor, breast cancer, and hepatocellular cancer. However, its exact functions and molecular mechanisms in ovarian cancer remain unclear. In this study, we found that TNKS was aberrantly overexpressed in human ovarian cancer tissues and associated with poor patient prognosis.

Objectives: To investigate the applicability and value of ultrasound (US) in the diagnosis of anorectal atresia.

Methods: Between January 2008 and January 2016, we prospectively evaluated 63,101 fetuses (gestational age, 20-38 weeks), including low- and high-risk populations using 2-dimensional US scans. An abnormal imaging finding was defined as an anal canal diameter of less than the 95% confidence interval (small anal canal) of the normal range or the absence of an anal canal and rectum.

The local treatment modalities in FIGO stage I-II small-cell carcinoma of the cervix are determined by disease stage and lymph node status.

The purpose of this study was to identify the optimal local treatment modalities for International Federation of Gynecology and Obstetrics (FIGO) stage I-II small-cell carcinoma of the cervix (SCCC), including cancer-directed surgery (CDS) and/or radiotherapy (RT). The Surveillance Epidemiology and End Results (SEER) database was used to identify SCCC patients from 1988 to 2012, and analyzed using Kaplan-Meier survival and Cox regression proportional hazard methods to determine factors significant for cause-specific survival (CSS) and overall (OS). A total of 208 patients of SCCC were enrolled.

Comparison of vitrified outcomes between human early blastocysts and expanded blastocysts.

We compared the vitrified outcomes between early and expanded blastocysts with or without laser drilling. The grade III embryos from the patients undergoing in vitro fertilization-embryo transfer (IVF-ET) in our reproductive center from September 2009 to February 2015 were incubated into early blastocysts and expanded blastocysts. The early blastocysts and expanded blastocysts were, respectively, divided into laser group (vitrification after laser drilling), non-laser group (direct vitrification), and control group (fresh non-vitrified blastocysts).

Role of PAFAH1B1 in human spermatogenesis, fertilization and early embryonic development.

Spermatogenesis, fertilization and subsequent embryonic development are complex processes that require tight regulation. The PAFAH1B1 gene plays important roles in these reproductive events in mice, but its expression and roles in human reproduction have not been investigated. Expression analysis of testicular tissue by reverse transcription quantitative PCR and immunohistochemistry revealed varied expression levels among samples of different spermatogenic abilities (as assessed by the Johnsen score), with protein expression restricted to spermatogonia, spermatocytes and spermatids.

Impact of oxygen concentrations on fertilization, cleavage, implantation, and pregnancy rates of in vitro generated human embryos.

The aim of the present study was to determine the impact of oxygen concentration during in vitro culture of human oocytes and embryos on fertilization, cleavage, implantation, pregnancy, multiple gestation and abortion rates. Women 20-48 years old presenting for infertility treatment and accounting for 3484 in vitro fertilization/intracytoplasmic sperm injection cycles were included in the study. Oocytes/embryos were randomly allocated to be incubated under three different oxygen tension environments: (1) 20% O2 in air; (2) initially 20% O2 in air, followed on day 2 (2-4 cells stage) by 5% CO2, 5% O2 and 90% N2; and (3) 5% CO2, 5% O2 and 90% N2 throughout.
