DNA methylation is an important epigenetic modification that is essential for various developmental processes through regulating gene expression, genomic imprinting, and epigenetic inheritance. Mammalian genomic DNA methylation is established during embryogenesis by de novo DNA methyltransferases, DNMT3A and DNMT3B, and the methylation patterns vary with(More)
Autophagy is related to cancer and other diseases, and compromised autophagy could promote chromosome instability associated with carcinogenesis and tumor progression. The role of autophagy in the growth and metastasis of colorectal cancer (CRC) remains poorly understood. Beclin1 mediates autophagic initiation, and LC3 is a specific marker for autophagy.(More)
INTRODUCTION We present the treatment rationale and study design for the RELAY study (NCT02411448 ). This phase Ib/III study will assess safety, tolerability, and efficacy of the combination of ramucirumab with erlotinib in previously untreated stage IV non-small-cell lung cancer patients with an activating epidermal growth factor receptor (EGFR) mutation.(More)
Mutations in PTEN-induced kinase 1 (PINK1) gene cause PARK6 familial Parkinsonism, and loss of the stability of PINK1 may also contribute to sporadic Parkinson's disease (PD). Degradation of PINK1 occurs predominantly through the ubiquitin proteasome system (UPS), however, to date, few of the proteins have been found to regulate the degradation of PINK1.(More)
OBJECTIVE To describe total drinking water intake among primary and middle school students in one district of Shenzhen and to provide scientific evidence for adequate intakes of drinking water for different people in China. METHOD A total of 816 students from three primary and middle schools of Shenzhen was selected using three-stage random sampling(More)
To maximize their capacity to save lives and optimize resource allocation, animal shelters need to identify highly adoptable animals that are unlikely to be delayed on medical grounds before they can be made available for adoption. In this retrospective cohort study, our objective was to identify risk factors for delays from intake to approval for adoption(More)
BACKGROUND Unmet need for assistance with activities of daily living (ADLs) disability is associated with increased risk for future hospitalization. To further explore the association between unmet ADL need and future health outcomes, we examined the association between unmet need for ADL assistance and 1-year mortality. METHODS A prospective study of(More)
The phosphoinositide 3-kinases (PI3Ks) are a critical family of signaling enzymes that participate in many cellular processes that promote the transformation of a normal cell into a cancer cell. These processes include cancer cell proliferation, migration, and invasion. However, the correlation between PI3Ks and multidrug resistance (MDR) remains unclear.(More)
The field medical station in military hospital plays an important role in the military logistic system. To better accomplish the duty of medical support mission, the problems of medical equipment and material store house management in the field medical station are discussed. Some targeted suggestions are introduced from daily management and the use of(More)
OBJECTIVE To assess the diagnostic utility of transurethral cystoscopic biopsy in dogs with histologically confirmed transitional cell carcinoma (TCC) of the urinary bladder and urethra. DESIGN Retrospective case series. ANIMALS 92 dogs with histologically confirmed TCC. PROCEDURES Information on sex, breed, neuter status, body weight, tumor location,(More)
