PURPOSE: Previous studies have found that 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF) was associated with diabetes. This study aimed to investigate the relationship between abnormal increased CMPF levels and gestational diabetes mellitus (GDM). METHODS: We recruited 828 pregnant women, and all of them underwent an oral glucose tolerance test (OGTT). We screened out 141 GDM patients and 230 pregnant women with normal glucose tolerance as controls. The serum CMPF concentration in participants was measured, and the relationship between the serum CMPF concentration and various parameters and biochemical indices was analyzed...

Major depressive disorder (MDD) is a growing problem worldwide. Though, the etiology remains unresolved, circadian rhythm disturbances are frequently observed in MDD and thus is speculated to play a key role herein. The present study focuses on circadian rhythm disturbances in the chronic mild stress (CMS) animal model of depression and examined whether the atypical antidepressant, agomelatine, which is mediating its action via melatonergic and serotonergic receptors, is capable of resynchronizing the perturbed rhythm...

Endothelial cell dysfunction in obesity can be reduced by calorie restriction (CR), however it is unclear whether this benefit requires a concomitant weight loss or is it simply related to the reduced calorie intake per se. In our study serum was drawn from 41 obese women who were undergoing an 8-week dietary intervention with 15 - 30% energy deficit, and from 48 age- and sex-matched controls of normal weight. Serum was analysed for biomarkers of endothelial cell function, oxidative stress and inflammation...

Regulatory T cells play a crucial role in the homeostasis of the immune response. In addition to CD4(+)Foxp3(+) regulatory T cells, several subsets of Foxp3(-) regulatory T cells, such as T helper 3 (Th3) cells and type 1 regulatory T (Tr1) cells, have been described in mice and human. Accumulating evidence shows that naïve B cells contribute to tolerance and are able to promote regulatory T cell differentiation. Naïve B cells can convert CD4(+)CD25(-) T cells into CD25(+)Foxp3(-) regulatory T cells, named Treg-of-B cells by our group...

Phenotypic plasticity describes the phenotypic variation of a trait when a genotype is exposed to different environments. Understanding the genetic control of phenotypic plasticity in crops such as maize is of paramount importance for maintaining and increasing yields in a world experiencing climate change. Here, we report the results of genome-wide association analyses of multiple phenotypes and two measures of phenotypic plasticity in a maize nested association mapping (US-NAM) population grown in multiple environments and genotyped with ~2...

Despite recent developments in neuroimaging, alterations of brain functional connectivity in major depressive disorder (MDD) patients with suicidal ideation are poorly understood. This study investigated specific changes of suicidal ideation in functional connectivity of MDD patients. Whole brain functional connectivity in 46 patients with MDD (23 with suicidal ideation and 23 without) and 36 age- and gender- matched healthy controls were compared using resting-state functional Magnetic Resonance Imaging (fMRI) analyzed with network-based statistics (NBS) and graph-theoretical methods...

Macrophages are exquisite sensors of tissue homeostasis that can rapidly switch between pro- and anti-inflammatory or regulatory modes to respond to perturbations in their microenvironment. This functional plasticity involves a precise orchestration of gene expression patterns whose transcriptional regulators have not been fully characterized. We had previously identified the transcription factor NFAT5 as an activator of TLR-induced responses, and in this study we explore its contribution to macrophage functions in different polarization settings...

Plants employ stomatal closure and reduced growth to avoid water deficiency damage. Reduced levels of the growth-promoting hormone gibberellin (GA) lead to increased tolerance to water deficit, but the underlying mechanism is unknown. Here, we show that the tomato (Solanum lycopersicum) DELLA protein PROCERA (PRO), a negative regulator of GA signaling, acts in guard cells to promote stomatal closure and reduce water loss in response to water deficiency by increasing abscisic acid (ABA) sensitivity. The loss-of-function pro mutant exhibited increased stomatal conductance and rapid wilting under water-deficit stress...

The concerted transition model for multimeric proteins is a simple formulation for analyzing the behavior of transmitter-gated ion channels. Here, we use the model to examine the relationship between the EC50 for activation of the GABAA receptor by the transmitter GABA and basal activity employing concatemeric ternary GABAA receptors expressed in Xenopus oocytes. The basal activity reflects receptor function in the absence of transmitter, and can be changed either by mutation to increase constitutive activity, or by addition of a second agonist (acting at a different site) to increase background activity...

Epithelioid hemangioma is a locally aggressive vascular neoplasm, found in bones and soft tissue, whose cause is currently unknown, but may involve oncogene activation. FOS was one of the earliest viral oncogenes to be characterized and normal cellular FOS forms part of the activator protein 1 (AP-1) transcription factor complex which plays a pivotal role in cell growth, differentiation and survival as well as the DNA damage response. Despite this, to date, a causal link between aberrant FOS function and naturally occurring tumors has not been established...

Human Nucleic Acid Binding Protein 1 and 2 (hNABP1 and hNABP2, also known as hSSB2 and hSSB1) form two separate and independent complexes with two identical proteins, integrator complex subunit 3 (INTS3) and C9ORF80. We and other groups have demonstrated that hNABP1 and 2 are single stranded (ss) DNA and RNA binding proteins, and function in DNA repair; however, the function of INTS3 and C9OFR80 remains elusive. In this study, we purified recombinant proteins INTS3 and C9ORF80 to near homogeneity. Both proteins exist as a monomer in solution, however C9ORF80 exhibits anomalous behavior on SDS-PAGE and gel filtration because of 48% random coil present in the protein...

BACKGROUND: Early life events can affect health in later life. We hypothesised that low lung function (FEV1 <80% predicted) in early adulthood (25-40 years) is associated with higher prevalence and earlier incidence of respiratory, cardiovascular, and metabolic abnormalities, and premature death. METHODS: In this cohort analysis, we tested this hypothesis using data from the Framingham Offspring Cohort (FOC) and validated our observations in CARDIA (an independent cohort) and GenIII (which includes the direct descendants of FOC participants)...

Suzanne Vrshek-Schallhorn, Bradley M Avery, Maria Ditcheva, Vaibhav R Sapuram
Various internalizing risk factors predict, in separate studies, both augmented and reduced cortisol responding to lab-induced stress. Stressor severity appears key: We tested whether heightened trait-like internalizing risk (here, trait rumination) predicts heightened cortisol reactivity under modest objective stress, but conversely predicts reduced reactivity under more robust objective stress. Thus, we hypothesized that trait rumination would interact with a curvilinear (quadratic) function of stress severity to predict cortisol reactivity...

We assessed the associations between handgrip strength and functional independence, quality of life and depressive symptoms in 947 participants aged 65 years or over. Handgrip strength was measured with a dynamometer. Use of formal support and family/friend support was self-reported. Activities of daily living (ADL), quality of life and depressive symptoms were assessed using validated scales. Mean handgrip strength was 27.1kg (±10.3). Each 10kg increase in handgrip strength was associated with 39% reduced odds of impaired instrumental ADL...

BACKGROUND: Current practice for selecting pharmacological and non-pharmacological antidepressant treatments has yielded low response and remission rates in Major Depressive Disorder (MDD). Neuroimaging biomarkers of brain structure and function may be useful in guiding treatment selection by predicting response vs. non-response outcomes. METHODS: In this review, we summarize data from studies examining predictors of treatment response using structural and functional neuroimaging modalities, as they pertain to pharmacotherapy, psychotherapy, and stimulation treatment strategies...

BACKGROUND: Sarcopenia is an independent predictor of death after living-donor liver transplantation (LDLT). However, the ability of the Asian Working Group for Sarcopenia criteria for sarcopenia (defined as reduced skeletal muscle mass plus low muscle strength) to predict surgical outcomes in patients who have undergone LDLT has not been determined. METHODS: This study prospectively enrolled 366 patients who underwent LDLT at Kyushu University Hospital. Skeletal muscle area (determined by computed tomography), hand-grip strength, and gait speed were measured in 102 patients before LDLT...
