Prevalence of abnormal glucose metabolism in Chinese renal transplant recipients: a single centre study.

BACKGROUND Post-transplant diabetes mellitus (PTDM) after renal transplantation is associated with adverse outcome on patient and graft survival. Fasting blood glucose alone will underestimate diabetes and also ignores diagnosis of impaired glucose tolerance (IGT). IGT has a strong correlation with diabetes and cardiovascular risk. METHODS In this cross-sectional study, we estimate the prevalence of abnormal glucose metabolism (AGM) using oral glucose tolerance test (OGTT) and identify its predictive factors. Patients who received kidney transplantation in our centre without pre-transplant diabetes were recruited. OGTT was performed in patients with fasting glucose levels between 5.6 and 6.9 mmol/L for at least two occasions 6 months post-transplantation. RESULTS Of 119 patients recruited, 31 had OGTT performed. The prevalence of PTDM, IGT and IFG was 21.8 (26/119)%, 6.7 (8/119)% and 3.4 (4/119)% respectively. Thus the overall prevalence of AGM was 31.9%. Age (P = 0.003), body mass index (P = 0.032), hepatitis B seropositivity status (P = 0.01), CMV infection (P = 0.02) and acute rejection (P = 0.002) were all associated with development of AGM. Using multivariate analysis, only older age at transplant (OR 1.09), history of acute rejection (OR 3.40) and hepatitis B seropositivity (OR 3.13) were significantly associated with the development of AGM. CONCLUSION AGM is common in our renal transplant recipients.

Patients' views regarding choice of dialysis modality.

BACKGROUND Increasing patient numbers have resulted in pressure on dialysis centres and a need to reorganize dialysis treatment. This study explored patients' experiences with different dialysis modalities and investigated issues related to the patient's choice of modality, especially 'out-of-centre' dialysis (i.e. modalities other than CHD). METHODS Six focus group interviews were conducted with 24 dialysis patients, 3 pre-dialysis patients and 18 relatives. Each focus group comprised patients on one type of dialysis, i.e. CHD, self-care CHD, HHD, CAPD/APD, aAPD or pre-dialysis patients. Based on a semi-structured interview guide, the group discussions centred on advantages and disadvantages of dialysis modalities, problems experienced and their (possible) solutions and patient involvement in choice of modality. RESULTS The focus groups participants considered that each dialysis modality has its advantages and disadvantages. Flexibility, independence and feelings of security were key factors in determining choice of modality, with maintenance of a normal life being a major goal. Patients and their relatives want to participate in choice of modality, but a genuine offer of out-of-centre dialysis including professional support and appropriate and timely education is needed to encourage a greater use of modalities other than CHD. CONCLUSIONS No single dialysis modality emerged as offering the best solution for patients with end-stage renal disease. In the absence of absolute clinical contraindications, the treatment of choice should be the modality that best accommodates the patients' preferences for their daily activities and lifestyle. A move towards more patients on out-of-centre dialysis requires a greater focus on pre-dialysis patients and closer consideration of patients' preferences and current lifestyle.
Green-up dates in the Tibetan Plateau have continuously advanced from 1982 to 2011

As the Earth’s third pole, the Tibetan Plateau has experienced a pronounced warming in the past decades. Recent studies reported that the start of the vegetation growing season (SOS) in the Plateau showed an advancing trend from 1982 to the late 1990s and a delay from the late 1990s to 2006. However, the findings regarding the SOS delay in the later period have been questioned, and the reasons causing the delay remain unknown. Here we explored the alpine vegetation SOS in the Plateau from 1982 to 2011 by integrating three long-term time-series datasets of Normalized Difference Vegetation Index (NDVI): Global Inventory Modeling and Mapping Studies (GIMMS, 1982–2006), SPOT VEGETATION (SPOT-VGT, 1998–2011), and Moderate Resolution Imaging Spectroradiometer (MODIS, 2000–2011). We found GIMMS NDVI in 2001–2006 differed substantially from SPOT-VGT and MODIS NDVIs and may have severe data quality issues in most parts of the western Plateau. By merging GIMMS-based SOSs from 1982 to 2000 with SPOT-VGT–based SOSs from 2001 to 2011 we found the alpine vegetation SOS in the Plateau experienced a continuous advancing trend at a rate of ∼1.04 d·y−1 from 1982 to 2011, which was consistent with observed warming in springs and winters. The satellite-derived SOSs were proven to be reliable with observed phenology data at 18 sites from 2003 to 2011; however, comparison of their trends was inconclusive due to the limited temporal coverage of the observed data. Longer-term observed data are still needed to validate the phenology trend in the future.
Proteomic analysis of mononuclear cells of patients with minimal-change nephrotic syndrome of childhood.

UNLABELLED Background/Aims. Recently, peripheral blood mononuclear cell transcriptome analysis has identified genes that are upregulated in relapsing minimal-change nephrotic syndrome (MCNS). In order to investigate protein expression in peripheral blood mononuclear cells (PBMC) from relapsing MCNS patients, we performed proteomic comparisons of PBMC from patients with MCNS in relapse and controls. METHODS PBMC from a total of 20 patients were analysed. PBMC were taken from five patients with relapsing MCNS, four in remission, five patients with other glomerular diseases and six controls. Two dimensional electrophoresis was performed and proteome patterns were compared. RESULTS Automatic heuristic clustering analysis allowed us to pool correctly the gels from the MCNS patients in the relapse and in the control groups. Using hierarchical population matching, nine spots were found to be increased in PBMC from MCNS patients in relapse. Four spots were identified by mass spectrometry. Three of the four proteins identified (L-plastin, alpha-tropomyosin and annexin III) were cytoskeletal-associated proteins. Using western blot and immunochemistry, L-plastin and alpha-tropomyosin 3 concentrations were found to be enhanced in PBMC from MCNS patients in relapse. Conclusions. These data indicate that a specific proteomic profile characterizes PBMC from MCNS patients in relapse. Proteins involved in PBMC cytoskeletal rearrangement are increased in relapsing MCNS. We hypothesize that T-cell cytoskeletal rearrangement may play a role in the pathogenesis of MCNS by altering the expression of cell surface receptors and by modifying the interaction of these cells with glomerular cells.

MAPK phosphatase-1 is required for regulatory natural autoantibody-mediated inhibition of TLR responses

Naturally arising IgM antibodies, which recognize neo-determinants on apoptotic cell (AC) membranes, are present from birth and can be further induced by AC challenge. Such naturally arising IgM antibodies can suppress proinflammatory responses to purified agonists for Toll-like receptors (TLRs), as well as block the induction of IgG immune complex-induced in vitro and in vivo pathogenic responses. To investigate the responsible mechanisms, we studied the regulatory effects of IgM anti-AC antibody on responses in bone marrow-derived dendritic cells mediated by a range of different TLRs and found that addition of IgM anti-AC inhibited the activation of the primary MAPKs: ERK1/2, JNK, and particularly p38. This was dependent on the recruitment of either C1q or mannose-binding lectin, which are both early complement factors that tag ACs for innate immune recognition. Strikingly, MAPK inhibition of responses to TLR agonists, and to lupus IgG autoantibody-chromatin immune complexes, was found to correlate with, and had an absolute requirement for, the induction and nuclear localization of MAPK phosphatase-1, a factor known to mediate glucocorticoid suppression of immune responses. Further experiments showed that natural IgM antibodies in serum exhibited the same inhibitory properties. These studies elucidate a novel homeostatic pathway by which natural antibodies, which are products of the adaptive immune system, can directly blunt inflammatory responses by recruitment and coordination of a primitive regulatory pathway of the innate immune system.
Structural analysis of Stc1 provides insights into the coupling of RNAi and chromatin modification

Noncoding RNAs can modulate gene expression by directing modifications to histones that alter chromatin structure. In fission yeast, siRNAs produced via the RNAi pathway direct modifications associated with heterochromatin formation. siRNAs associate with the RNAi effector protein Argonaute 1 (Ago1), targeting the Ago1-containing RNA-induced transcriptional silencing (RITS) complex to homologous nascent transcripts. This promotes recruitment of the Clr4 complex (CLRC), which mediates methylation of histone H3 on lysine 9 (H3K9me) in cognate chromatin. A key question is how the RNAi and chromatin modification machineries are connected. Stc1 is a small protein recently shown to associate with both Ago1 and CLRC and to play a pivotal role in mediating the RNAi-dependent recruitment of CLRC to chromatin. To understand its mode of action, we have performed a detailed structural and functional analysis of the Stc1 protein. Our analyses reveal that the conserved N-terminal region of Stc1 represents an unusual tandem zinc finger domain, with similarities to common LIM domains but distinguished by a lack of preferred relative orientation of the two zinc fingers. We demonstrate that this tandem zinc finger domain is involved in binding Ago1, whereas the nonconserved C-terminal region mediates association with CLRC. These findings elucidate the molecular basis for the coupling of RNAi to chromatin modification in fission yeast.
The role of the adipokine chemerin in prostate cancer

Obesity is a major health problem worldwide and its effects on the cardiovascular system are well documented. It also leads to the development of metabolic disease such as insulin resistance and diabetes. There is evidence that obesity leads to an increased risk of developing numerous malignancies. Indeed, obese individuals diagnosed with malignancy tend to have poorer outcomes in terms of survival. A possible explanation for this is through the action of obesity-related cytokines (adipokines). These may play a role in either propagating, or perpetuating carcinogenesis and I explored the role of one particular adipokine: chemerin in prostate cancer. Prostate cancer cell lines (PC3 & LNCaP) were used for cell proliferation, migration, invasion and apoptosis assays. Western blot analysis and qRT-PCR techniques were used to evaluate the effects of chemerin on levels of key intracellular agents of carcinogenesis (bcl-2, p53, ERK and AKT) as well as novel, pro-cancerous genes such as anterior gradient 2 (AGR2). Serum samples were obtained from adult men with prostate disease to evaluate whether chemerin is associated with body parameters. Chemerin exerts positive effects on cellular proliferation and migration as well as inhibition of apoptosis in prostate cancer cells. These effects may be mediated by increased expression of the oncogene: bcl-2. Bcl2 expression was elevated in both cell lines after 24 hours stimulation with chemerin at increasing doses. Chemerin also appeared to cause activation of ERK and AKT pathways in prostate cancer cells as well as increased expression of the pro metastatic AGR2 gene at both the mRNA and protein level. An ELISA demonstrated chemerin behaving as an adipokine in adult men with prostate disease in keeping with previously published data. Chemerin certainly appears to play a role in prostate carcinogenesis, at least at the cellular level.
Interobserver variability of clinical scores in hidradenitis suppurativa is low

Background Hidradenitis suppurativa (HS) is a chronic recurrent disease with scars and sinus tract formation that causes substantial impact on quality of life. For evaluation of HS and treatment results, a scoring system for disease severity (Hidradenitis Suppurativa Score, HSS) has been proposed.
Are Pregnant Women Happier? Racial Differences in the Relationsip between Pregnancy and Life Satisfaction

This paper uses data from the Behavioral Risk Factor Surveillance System (BRFSS) to study the relationship between pregnancy and life satisfaction for women of childbearing age. The results show strong differences by race. Pregnancy has the strongest positive correlation with happiness for Whites, a smaller but still statistically significant positive correlation for Hispanics, and no relationship for Blacks. The results cannot be explained by differences in other demographics such age, income, education, or marital status. Within each racial group, the results hold across different categories for all these characteristics. There is evidence that racial differences in the effects of pregnancy on emotional and social support from others can partly explain this result.
TRIM39 regulates cell cycle progression and DNA damage responses via stabilizing p21

The biological function of Tripartite Motif 39 (TRIM39) remains largely unknown. In this study, we report that TRIM39 regulates the steady-state levels of p21 and is a pivotal determinant of cell fate. Ablation of TRIM39 leads to destabilization of p21 and increased G1/S transition in unperturbed cells. Furthermore, DNA damage-induced p21 accumulation is completely abolished in cells with depleted TRIM39. As a result, silencing of TRIM39 abrogates the G2 checkpoint induced by genotoxic stress, leading to increased mitotic entry and, ultimately, apoptosis. Importantly, we show p21 is a crucial downstream effector of TRIM39 mediating G1/S transition and DNA damage-induced G2 arrest. Mechanistically, TRIM39 interacts with p21, which subsequently prevents Cdt2 from binding to p21, therefore blocking ubiquitylation and proteasomal degradation of p21 mediated by CRL4Cdt2 E3 ligase. Strikingly, we found a significant correlation between p21 abundance and TRIM39 expression levels in human hepatocellular carcinoma samples. Our findings identify a causal role for TRIM39 in regulating cell cycle progression and the balance between cytostasis and apoptosis after DNA damage via stabilizing p21.
Splicing program of human MENA produces a previously undescribed isoform associated with invasive, mesenchymal-like breast tumors

Human mena (hMENA), a member of the actin cytoskeleton regulators Ena/VASP, is overexpressed in high-risk preneoplastic lesions and in primary breast tumors and has been identified as playing a role in invasiveness and poor prognosis in breast cancers that express HER2. Here we identify a unique isoform, hMENAΔv6, derived from the hMENA alternative splicing program. In an isogenic model of human breast cancer progression, we show that hMENA11a is expressed in premalignant cells, whereas hMENAΔv6 expression is restricted to invasive cancer cells. “Reversion” of the malignant phenotype leads to concurrent down-regulation of all hMENA isoforms. In breast cancer cell lines, isoform-specific hMENA overexpression or knockdown revealed that in the absence of hMENA11a, overexpression of hMENAΔv6 increased cell invasion, whereas overexpression of hMENA11a reduced the migratory and invasive ability of these cells. hMENA11a splicing was shown to be dependent on the epithelial regulator of splicing 1 (ESRP1), and forced expression of ESRP1 in invasive mesenchymal breast cancer cells caused a phenotypic switch reminiscent of a mesenchymal-to-epithelial transition (MET) characterized by changes in the cytoskeletal architecture, reexpression of hMENA11a, and a reduction in cell invasion. hMENA-positive primary breast tumors, which are hMENA11a-negative, are more frequently E-cadherin low in comparison with tumors expressing hMENA11a. These data suggest that polarized and growth-arrested cellular architecture correlates with absence of alternative hMENA isoform expression, and that the hMENA splicing program is relevant to malignant progression in invasive disease.
Developing academic persistence in first year tertiary students: a case study

Teachers and researchers of undergraduate university students agree that the first year experience can have a major impact on later study participation and academic performance. Specifically, the transition to university study from school or other contexts requires that first year students demonstrate the characteristics of self-directed learners, as they enter an environment with minimal constraints and an expectation of self-motivation and individual effort. Art Costa (1991) identified several such characteristics that he terms habits of mind, suggesting that demonstration of these habits will enhance the academic success of learners. The aim of this research project was to identify teaching and learning strategies that have the potential to assist first year university students to persist at a task. Persistence is one of Costa’s habits, and is related to one of the Seven Principles of Good Practice in Undergraduate Education, recently adopted by Central Queensland University in the pursuit of enhanced teaching and learning outcomes for staff and students alike. This paper outlines the data gathered from a tutor of first year undergraduate teacher education students enrolled in a Queensland regional campus. The data presented here were gathered through a participant journal and an individual interview at the end of the term. Analysis of the data revealed that student persistence can be developed and enhanced through the use of teaching and learning strategies with a focus on explicit teacher talk, reflection on learning, shared experiences and positive feedback.
The Fluid Joint: The Soft Spot of Micro‐ and Nanosystems

Fluid bridges are ubiquitous soft structures of finite size that conform to and link the surfaces of neighboring objects. Fluid joints, the specific type of fluid bridge with at least one extremity constrained laterally, display even more pronounced reactivity and self‐restoration, which make them remarkably suited for assembly, actuation, and manipulation purposes. Their peculiar surface and bulk properties place fluid joints at the rich intersection of diverse scientific interests, and foster their widespread use throughout micro‐ and nanotechnology. A critical survey of the mechanics and of the manifold applications of fluid bridges and joints in micro‐ and nanosystems is presented here, along with current challenges and multidisciplinary perspectives.
Biogeography of time partitioning in mammals

Significance The majority of mammal species are nocturnal, but many are diurnal (active during the day), crepuscular (active mostly during twilight), or cathemeral (active during hours of daylight and darkness). These different strategies for regulating activity over a 24-h cycle are associated with suites of adaptations to light or semidarkness. The biogeography of these time partitioning strategies is, however, poorly understood. We show that global patterns in mammal diversity with different diel activity patterns are constrained by the duration of time that is both (i) illuminated by daylight, moonlight, and/or twilight and (ii) between thermal limits suitable for mammal activity. Many animals regulate their activity over a 24-h sleep–wake cycle, concentrating their peak periods of activity to coincide with the hours of daylight, darkness, or twilight, or using different periods of light and darkness in more complex ways. These behavioral differences, which are in themselves functional traits, are associated with suites of physiological and morphological adaptations with implications for the ecological roles of species. The biogeography of diel time partitioning is, however, poorly understood. Here, we document basic biogeographic patterns of time partitioning by mammals and ecologically relevant large-scale patterns of natural variation in “illuminated activity time” constrained by temperature, and we determine how well the first of these are predicted by the second. Although the majority of mammals are nocturnal, the distributions of diurnal and crepuscular species richness are strongly associated with the availability of biologically useful daylight and twilight, respectively. Cathemerality is associated with relatively long hours of daylight and twilight in the northern Holarctic region, whereas the proportion of nocturnal species is highest in arid regions and lowest at extreme high altitudes. Although thermal constraints on activity have been identified as key to the distributions of organisms, constraints due to functional adaptation to the light environment are less well studied. Global patterns in diversity are constrained by the availability of the temporal niche; disruption of these constraints by the spread of artificial lighting and anthropogenic climate change, and the potential effects on time partitioning, are likely to be critical influences on species’ future distributions.
