Background: Intracellular Ca cycling determines myocardial contraction and relaxation in response to physiological demands. SERCA2a (sarcoplasmic/endoplasmic reticulum Ca-ATPase 2a) is responsible for the sequestration of cytosolic Ca into intracellular stores during cardiac relaxation, and its activity is reversibly inhibited by PLN (phospholamban). However, the regulatory hierarchy of SERCA2a activity remains unclear.

Arginase, a manganese (Mn)-dependent enzyme, is indispensable for urea generation and ammonia disposal in the liver. The potential role of fructose in Mn and ammonia metabolism is undefined. Here we demonstrate that fructose overconsumption impairs hepatic Mn homeostasis and ammonia disposal in male mice.

The mammalian cochlear epithelium undergoes substantial remodeling and maturation before the onset of hearing. However, very little is known about the transcriptional network governing cochlear late-stage maturation and particularly the differentiation of its lateral nonsensory region. Here, we establish ZBTB20 as an essential transcription factor required for cochlear terminal differentiation and maturation and hearing.

Background: The association between serum erythrocyte immune function indexes and blue light treatment effect and severity in child patients with pathological jaundice was testified.

Methods: One hundred and seven children with pathological jaundice and 69 children with physiological jaundice were enrolled to analyze the association between erythrocyte immune function indexes and blue light treatment or disease progression.

Results: The area under the ROC curve (AUC) of red blood cell immune complex rosettes (RBC-ICR) and red blood cell C3b receptor rosette (RBC-C3bR) in diagnosing pathological jaundice and assessing the efficacy of blue light therapy overweighed 0.

Objective: To investigate the longitudinal prediction of intensity and emotional connection (EC) related to online social networking use at baseline on the risk of incident depression at nine-month follow-up among adolescents.

Methods: A total of 3196 secondary school students, who were online social networking users and free of depression at baseline, were included in this study. Multilevel logistic regression models were applied to investigate the longitudinal prediction of two dimensions of online social networking use intensity (social function use intensity (SFUI), entertainment function use intensity (EFUI)) and EC scores at baseline on incident depression at follow-up.

Background And Aims: Lipoprotein lipase (LPL) is responsible for the lipolytic processing of triglyceride-rich lipoproteins, the deficiency of which causes severe hypertriglyceridemia. Liver LPL expression is high in suckling rodents but relatively low at adulthood. However, the regulatory mechanism and functional significance of liver LPL expression are incompletely understood.

Objective: We aimed to investigate the potential roles of interpersonal psychosocial factors on the association between online social networking use intensity and depressive symptoms among early adolescents.

Methods: A total of 4237 adolescents from a 9-month longitudinal study were included.

The zinc-finger protein ZBTB20 regulates development and metabolism in multiple systems, and is essential for postnatal survival in mice. However, its potential role in the cardiovascular system remains undefined. Here, we demonstrate that ZBTB20 is critically involved in the regulation of cardiac contractility and blood pressure in mice.

Background And Aims: Problematic online social networking use is prevalent among adolescents, but consensus about the instruments and their optimal cut-off points is lacking. This study derived an optimal cut-off point for the validated Online Social Networking Addiction (OSNA) scale to identify probable OSNA cases among Chinese adolescents.

Methods: A survey recruited 4,951 adolescent online social networking users.

Excessive fructose consumption is closely linked to the pathogenesis of metabolic disease. Carbohydrate response element-binding protein (ChREBP) is a transcription factor essential for fructose tolerance in mice. However, the functional significance of liver ChREBP in fructose metabolism remains unclear.

Background: Providing care often causes negative reactions and psychological distress in family caregivers of patients with heart failure. How these 2 constructs are related has not been fully explored.

Objective: The aims of this study were to describe caregiver reactions to caregiving and psychological distress and to determine the associations between caregiver reactions to caregiving and psychological distress in family caregivers of patients with heart failure.

The acquired gene, which encodes a ribosomal protection protein of the ABC-F family, can confer cross-resistance to linezolid and florfenicol, posing a serious therapeutic challenge to both human and veterinary medicine. The objective of this study was to investigate the two () plasmids for their fine structure, their transferability and the presence of mobile antimicrobial resistance loci. To elucidate their fine structure, the two plasmids were completely sequenced and the sequences analysed.

Background And Aims: The aim of this study is to estimate the longitudinal associations between online social networking addiction (OSNA) and depression, whether OSNA predicts development of depression, and reversely, whether depression predicts development of OSNA.

Methods: A total of 5,365 students from nine secondary schools in Guangzhou, Southern China were surveyed at baseline in March 2014, and followed up 9 months later. Level of OSNA and depression were measured using the validated OSNA scale and CES-D, respectively.

Liver has a unique regenerative capacity, however, its regulatory mechanism is not fully defined. We have established the zinc-finger protein ZBTB20 as a key transcriptional repressor for alpha-fetoprotein (AFP) gene in liver. As a marker of hepatic differentiation, AFP expression is closely associated with hepatocyte proliferation.

Hepatic de novo lipogenesis (DNL) converts carbohydrates into triglycerides and is known to influence systemic lipid homoeostasis. Here, we demonstrate that the zinc finger protein Zbtb20 is required for DNL. Mice lacking Zbtb20 in the liver exhibit hypolipidemia and reduced levels of liver triglycerides, along with impaired hepatic lipogenesis.

Long-term exposure to therapeutic doses of glucocorticoids (GCs) results in bone remodeling, which frequently causes osteoporosis and fracture healing retardation because of the abnormality of osteoblastic proliferation and differentiation. The mechanisms of GCs' effect on osteoblasts are largely unknown. In this present study, we found that dexamethasone (Dex) could induce the expression of the small G protein, RhoB, in mRNA and protein levels in the osteoblast-derived osteosarcoma cell lines MG-63.

The anterior pituitary harbours five distinct hormone-producing cell types, and their cellular differentiation is a highly regulated and coordinated process. Here we show that ZBTB20 is essential for anterior pituitary development and lactotrope specification in mice. In anterior pituitary, ZBTB20 is highly expressed by all the mature endocrine cell types, and to some less extent by somatolactotropes, the precursors of prolactin (PRL)-producing lactotropes.

Background: Levetiracetam (Lev) is a new antiepileptic drugs, proved to be effective and tolerance in regulatory trials, but these controlled trials do not always predict how useful a drug will be in day to day clinical practice, Retention rates can provide a better indication of efficacy and tolerability in everyday use.

Methods: Totally 124 patients with more than 3 months disease course were enrolled in the study from June 2007 to December 2007. The LEV dose ranged from 10 to 60 mg/kg per day.

Background: Placental production of corticotrophin releasing hormone (CRH) rises exponentially as pregnancy progresses, and has been linked with the onset of normal and preterm labour. CRH is produced in syncytiotrophoblast cells and production is increased by glucocorticoids and cAMP. It remains unclear whether cAMP acts by inducing differentiation of cytotrophoblasts and/or through induction of syncytialisation.
