No Significant Difference between Plasma miRNAs and Plasma-Derived Exosomal miRNAs from Healthy People

Fei Tian, Yanting Shen, Zhenzhu Chen et al. · 2017 · BioMed Research International

BACKGROUND: MicroRNAs (miRNAs) are small noncoding RNAs that are involved in many biological regulation processes. Studies have reported that miRNAs are enriched in human plasma and plasma-derived exosome as novel diagnostic biomarkers. The aim of this study was to determine whether the miRNA expression levels are different between plasma and plasma-derived exosome. METHODS: We sequenced and quantified the miRNAs in plasma and exosome from healthy blood samples and validated three miRNAs in the two groups of lung cancer samples by qRT-PCR. RESULTS: The sequencing results showed that only sever

Genome-wide association data suggest ABCB1 and immune-related gene sets may be involved in adult antisocial behavior

Jessica E. Salvatore, Alexis C. Edwards, Jeanette N. McClintick et al. · 2015 · Translational Psychiatry

Adult antisocial behavior (AAB) is moderately heritable, relatively common and has adverse consequences for individuals and society. We examined the molecular genetic basis of AAB in 1379 participants from a case-control study in which the cases met criteria for alcohol dependence. We also examined whether genes of interest were expressed in human brain. AAB was measured using a count of the number of Antisocial Personality Disorder criteria endorsed under criterion A from the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV). Participants were genotyped on the Illumi

An optimised patient information sheet did not significantly increase recruitment or retention in a falls prevention study: an embedded randomised recruitment trial

Sarah Cockayne, Caroline Fairhurst, Joy Adamson et al. · 2017 · Trials

BACKGROUND: Randomised controlled trials are generally regarded as the 'gold standard' experimental design to determine the effectiveness of an intervention. Unfortunately, many trials either fail to recruit sufficient numbers of participants, or recruitment takes longer than anticipated. The current embedded trial evaluates the effectiveness of optimised patient information sheets on recruitment of participants in a falls prevention trial. METHODS: A three-arm, embedded randomised methodology trial was conducted within the National Institute for Health Research-funded REducing Falls with ORth

Wisdom of crowds and collective decision-making in a survival situation with complex information integration

Daisuke Hamada, Masataka Nakayama, Jun Saiki · 2020 · Cognitive Research Principles and Implications

BACKGROUND: The wisdom of crowds and collective decision-making are important tools for integrating information between individuals, which can exceed the capacity of individual judgments. They are based on different forms of information integration. The wisdom of crowds refers to the aggregation of many independent judgments without deliberation and consensus, while collective decision-making is aggregation with deliberation and consensus. Recent research has shown that collective decision-making outperforms the wisdom of crowds. Additionally, many studies have shown that metacognitive knowled

No association between serum cholesterol and death by suicide in patients with schizophrenia, bipolar affective disorder, or major depressive disorder

Subin Park, Ki Kyoung Yi, Riji Na et al. · 2013 · Behavioral and Brain Functions

BACKGROUND: Previous research on serum total cholesterol and suicidality has yielded conflicting results. Several studies have reported a link between low serum total cholesterol and suicidality, whereas others have failed to replicate these findings, particularly in patients with major affective disorders. These discordant findings may reflect the fact that studies often do not distinguish between patients with bipolar and unipolar depression; moreover, definitions and classification schemes for suicide attempts in the literature vary widely. METHODS: Subjects were patients with one of the th

Analysis of rare Parkinson’s disease variants in millions of people

Vanessa Pitz, Mary B. Makarious, Sara Bandrés‐Ciga et al. · 2024 · npj Parkinson s Disease

Although many rare variants have been reportedly associated with Parkinson's disease (PD), many have not been replicated or have failed to replicate. Here, we conduct a large-scale replication of rare PD variants. We assessed a total of 27,590 PD cases, 6701 PD proxies, and 3,106,080 controls from three data sets: 23andMe, Inc., UK Biobank, and AMP-PD. Based on well-known PD genes, 834 variants of interest were selected from the ClinVar annotated 23andMe dataset. We performed a meta-analysis using summary statistics of all three studies. The meta-analysis resulted in five significant variants

LAG-3 expression in the inflammatory microenvironment of glioma

Maximilian J. Mair, Barbara Kiesel, Katharina Feldmann et al. · 2021 · Journal of Neuro-Oncology

PURPOSE: Immune modulatory therapies including immune checkpoint inhibitors have so far failed to result in clinically meaningful efficacy in glioma. We aimed to investigate lymphocyte activation gene 3 (LAG-3), an inhibitory receptor on immune cells and target of second-generation immune checkpoint inhibitors, in glioma. METHODS: 97 patients with diffuse glioma (68 with glioblastoma, 29 with WHO grade II-III glioma) were identified from the Neuro-Biobank of the Medical University of Vienna. LAG-3 expression in the inflammatory microenvironment was assessed by immunohistochemistry (monoclonal

Dark chocolate supplementation reduces the oxygen cost of moderate intensity cycling

Rishikesh Kankesh Patel, James Brouner, Owen Spendiff · 2015 · Journal of the International Society of Sports Nutrition

BACKGROUND: Dark chocolate (DC) is abundant in flavanols which have been reported to increase the bioavailability and bioactivity of nitric oxide (NO). Increasing NO bioavailability has often demonstrated reduced oxygen cost and performance enhancement during submaximal exercise. METHODS: Nine moderately-trained male participants volunteered to undertake baseline (BL) measurements that comprised a cycle V̇O(2max) test followed by cycling at 80% of their established gas exchange threshold (GET) for 20-min and then immediately followed by a two-minute time-trial (TT).

Revealing the role of SPP1+ macrophages in glioma prognosis and therapeutic targeting by investigating tumor-associated macrophage landscape in grade 2 and 3 gliomas

Wenshu Tang, Cario W. S. Lo, Wei Ma et al. · 2024 · Cell & Bioscience

BACKGROUND: Glioma is a highly heterogeneous brain tumor categorized into World Health Organization (WHO) grades 1-4 based on its malignancy. The suppressive immune microenvironment of glioma contributes significantly to unfavourable patient outcomes. However, the cellular composition and their complex interplays within the glioma environment remain poorly understood, and reliable prognostic markers remain elusive. Therefore, in-depth exploration of the tumor microenvironment (TME) and identification of predictive markers are crucial for improving the clinical management of glioma patients. RE

Myeloperoxidase-specific antineutrophil cytoplasmic antibody-associated vasculitis

Sabrina Arnold, A. Richard Kitching, Véronique Witko‐Sarsat et al. · 2024 · The Lancet Rheumatology

Myeloperoxidase (MPO)-specific antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (MPO-ANCA-associated vasculitis) is one of two major ANCA-associated vasculitis variants characterised by systemic necrotising vasculitis with few or no immune deposits. MPO-ANCA-associated vasculitis predominantly affects small blood vessels and, in contrast to its counterpart proteinase 3-ANCA-associated vasculitis, is generally not associated with granulomatous inflammation. The kidneys and lungs are the most commonly affected organs. The pathogenesis of MPO-ANCA-associated vasculitis is characte

Ultra-radical upfront surgery does not improve survival in women with advanced epithelial ovarian cancer; a natural experiment in a complete population

Henrik Falconer, Ulrika Joneborg, Kamilla Krawiec et al. · 2020 · Gynecologic Oncology

OBJECTIVE: Ultra-radical surgery to achieve complete resection in advanced epithelial ovarian cancer (EOC) has been widely accepted without strong supporting data. Our objective was to assess overall survival after a structured shift to an ultra-radical upfront surgical treatment algorithm and to investigate changes in the distribution of primary treatments after this shift. PATIENTS AND METHODS: In this population-based cohort study, all women with suspected EOC in the Stockholm-Gotland region of Sweden reported to the Swedish Quality Registry for Gynecologic Cancer (SQRGC) and National Cance
