PURPOSE: To examine whether the effects of psychosocial and vocational interventions delivered in the first 3 mo post-acute myocardial infarction (AMI) are effective for improving work outcomes compared with other interventions. METHODS: A search was completed for English language publications up to March 2016 across 4 electronic databases and gray literature. Inclusion criteria were (1) psychosocial and/or vocational interventions; (2) adults 18 years or older with an AMI who were within the first 3 mo post-AMI; (3) randomized or clinically controlled trials; and (4) reporting of at least 1 return-to-work (RTW) outcome: including return to paid/unpaid employment, either full-time or part-time, to the previous job role or on modified duties...

Amino acids represent an important component in the diet of the Venus flytrap (Dionaea muscipula), and supply plants with much needed nitrogen resources upon capture of insect prey. Little is known about the significance of prey-derived carbon backbones of amino acids for the success of Dionaea's carnivorous life-style. The present study tracked changes in plant amino acid pools and their δ(13) C- and δ(15) N-signatures, after half of all traps per plant had been fed with contrasting amounts of double-labeled insect powder (0, 5, 10 and 20 mg per trap)...

Milk fat determines the quality of milk and is also a main targeted trait in dairy cow breeding. Recent studies have revealed important regulatory roles of microRNAs (miRNA) in milk fat synthesis in the mammary gland. However, the role of miRNA in bovine mammary epithelial cells (BMEC) remains largely unknown. In this study, we found that the overexpression of miR-130a significantly decreased cellular triacylglycerol (TAG) levels and suppressed lipid droplet formation, whereas the inhibition of miR-130a resulted in greater lipid droplet formation and TAG accumulation in BMEC...

Glucocorticoids (GC) are essential regulators of T-cell development and function. Activation of the immune system increases systemic adrenal-derived GC levels which downregulate immune activity as part of a negative feedback control system. Increasing evidence shows, however, that GC can also be derived from extra-adrenal sources such as the thymus or intestine, thus providing local control of GC-mediated effects. The thymus reportedly produces GC, but whether thymic epithelial cells or thymocytes produce GC acting either in an autocrine or paracrine fashion is not clear...

An atom and step economic access to unprotected meta-substituted primary anilines was disclosed via the Semmler-Wolff reaction promoted by molecular iodine, in which noble metal catalysts and inert atmosphere are unnecessary while the forcing reaction conditions and the lengthy synthesis can be avoided. The synthetic utility of this approach is evident in the de novo syntheses of three bioactive molecules with good total yields.

BACKGROUND: Epidermal growth factor receptor (EGFR), a well-known oncogenic driver, contributes to the initiation and progression of a wide range of cancer types. Aberrant lipid metabolism including highly produced monounsaturated fatty acids (MUFA) is recognized as a hallmark of cancer. However, how EGFR regulates MUFA synthesis in cancer remains elusive. This is the focus of our study. METHODS: The interaction between EGFR and stearoyl-CoA desaturase-1 (SCD1) was detected byco-immunoprecipitation...

Circular RNAs (circRNAs), a novel class of long noncoding RNAs, are characterized by a covalently closed continuous loop without 5' or 3' polarities structure and have been widely found in thousands of lives including plants, animals and human beings. Utilizing the high-throughput RNA sequencing (RNA-seq) technology, recent findings have indicated thata great deal of circRNAs, which are endogenous, stable, widely expressed in mammalian cells, often exhibit cell type-specific, tissue-specific or developmental-stage-specific expression...

Serotonin (5-HT) is a neuromodulator involved in several central-mediated mechanisms, such as endocrine processes, behavior, and sleep. Dysfunction of the serotonergic system is mainly linked to psychiatric disorders, but emerging evidence suggests that immune system activation may also alter brain 5-HT signaling. However, whether central 5-HT modulates systemic inflammation (SI) remains unknown. For this purpose, male Wistar rats (280-350 g, 8-9 weeks) were submitted to the experimental protocols beginning between 9 and 10 AM with the performance of injections...

Epithelial to mesenchymal transition (EMT) is a developmental program reactivated by tumor cells that leads to the switch from epithelial to mesenchymal phenotype. During EMT, cells are transcriptionally regulated to decrease E-cadherin expression while expressing mesenchymal markers such as vimentin, fibronectin and N-cadherin. Growing body of evidences suggest that cells engaged in EMT undergo a metabolic reprograming process, redirecting glucose flux toward Hexosamine Biosynthesis Pathway (HBP) which fuels aberrant glycosylation patterns that are extensively observed in cancer cells...

BACKGROUND: The suicidal death of erythrocytes should be considered a possible cause of hemolysis and plasma bilirubin overload when there is no evidence of an immune-mediated hemolytic anemia, no consumptive red blood cell disorder, no morphologic or laboratory data to suggest a problem of the red cell membrane, and no evidence of a quantitative or qualitative defect in hemoglobin synthesis. OBJECTIVE: In neonatal period, xenobiotics, cytokines, osmotic shock, energy depletion, oxidative stress, and variation of temperature may induce an alteration of balance between damaging and protecting factors which can be followed by red cell death...

Autosomal dominant optic atrophy (ADOA) is a dominantly inherited optic neuropathy, affecting the specific loss of retinal ganglion cells (RGCs). The majority of affected cases of ADOA are associated with mutations in OPA1 gene. Our previous investigation identified the c.1198C > G (p.P400A) mutation in the OPA1 in a large Han Chinese family with ADOA. In this report, we performed a functional characterization using lymphoblostoid cell lines derived from affected members of this family and control subjects...

Chronic ACTH exposure (eg Cushings) is associated with adrenal hypertrophy and steroidogenesis. The underlying molecular processes in mice have been analysed by microarray, histological and immunohistochemical techniques. Synacthen infused for 2weeks markedly increased adrenal mass and plasma corticosterone levels. Microarray analysis found greater than 2-fold changes in expression of 928 genes (P<0.001; 397 up, 531 down). These clustered in pathways involved in signalling, sterol/lipid metabolism, cell proliferation/hypertrophy and apoptosis...

BACKGROUND: Advanced analytic methods for synthesizing evidence about complex interventions continue to be developed. In this paper, we emphasize that the specific research question posed in the review should be used as a guide for choosing the appropriate analytic method. RATIONALE: We present advanced analytic approaches that address four common questions that guide reviews of complex interventions: 1) How effective is the intervention?; 2) For whom does the intervention work and in what contexts?; 3) What happens when the intervention is implemented?; and 4) What decisions are possible given the results of the synthesis? DISCUSSION: The analytic approaches presented in this paper are particularly useful when each primary study differs in components, mechanisms of action, context, implementation, timing, and many other domains...
