OBJECTIVE: Childhood trauma is common and associated with both worse cognitive performance and disruption to the hypothalamic-pituitary-adrenal axis in younger adults. The extent to which these associations persist into older adulthood remains unknown. The aim of this study was to investigate self-reported childhood trauma in relation to cognitive performance, and the extent to which cortisol explained this association, in 2 independent samples of older adults. METHODS: In this cross-sectional study, participants in the discovery sample (N = 76) consisted of older adults with a DSM-IV diagnosis of generalized anxiety disorder (N = 57) and age-equated psychiatrically healthy comparison subjects (N = 19) who were referred largely through primary care clinics between 2004-2006...

Background: Migraine pathophysiology involves a neuronal mechanism that is closely associated with the neuronal activation of peripheral trigeminal nociceptive pathways. It also involves a vascular mechanism that is supported by studies concerning the presence of migraine with aura in various vascular diseases. Migraine is associated with silent infarct-like lesions and white matter hyperintensities (WMHs) that can be encountered during magnetic resonance imaging. In this study, we aimed to demonstrate the migraine-WMH link based on pain lateralization...

Human rhinoviruses (HRVs) are the commonest cause of the common cold. While less pathogenic compared to other respiratory viruses, it is frequently associated with exacerbation of chronic respiratory diseases such as rhinosinusitis and asthma exacerbation. Currently, there are limited studies on HRV infection of nasal epithelial cells despite being the first site of viral contact, immune initiation, and airway inter-connectivity. Hence, we established a model of HRV infection of in vitro differentiated human nasal epithelial cells (hNECs) derived from multiple individuals...

Ovarian folliculogenesis is always of great interest in reproductive biology. However, the molecular mechanisms that control follicle development, particularly the early phase of follicle activation or recruitment, still remain poorly understood. In an attempt to decipher the gene networks and signaling pathways involved in such transition, we conducted a transcriptomic analysis (RNA-seq) on zebrafish primary growth (PG, stage I; inactive) and pre-vitellogenic (PV, stage II; activated) follicles. A total of 118 unique microRNAs (miRNAs) (11 down-regulated and 83 up-regulated during PG/PV transition) and 56711 unique messenger RNAs (mRNAs) (1839 down-regulated and 7243 up-regulated during PG/PV transition) were identified...

Neutrophils are found to be infiltrated in tumour tissues of patients with colitis-associated cancer (CAC) and colorectal cancer (CRC), and CD177 is mainly expressed in neutrophils. In our study, expression of CD177 in tumour tissues from patients with CAC or CRC was analysed by qRT-PCR, flow cytometry, and immunohistochemistry. We recruited 378 patients with CRC, determined CD177 expression in tumours, and examined its correlation with clinicopathological features. Moreover, CAC model was induced in wild type (WT) and CD177-/- mice by azoxymethane (AOM)/dextran sodium sulfate (DSS)...

Importance: Multiple disease processes are associated with cognitive impairment in Parkinson disease (PD), including Lewy bodies, cerebrovascular disease, and Alzheimer disease. It remains unknown whether tau pathology relates to cognition in patients with PD without dementia. Objective: To compare tau aggregation in patients with PD who are cognitively normal (PD-CN), patients with PD with mild cognitive impairment (PD-MCI), and healthy control participants, and evaluate the relationships between β-amyloid (Aβ), tau, and cognition in patients with PD who did not have dementia...

Chronic inflammation results when the immune system responds to trauma, injury or infection and the response is not resolved. It can lead to tissue damage and dysfunction and in some cases predispose to cancer. Some viruses (including Epstein-Barr virus (EBV)) can induce inflammation, which may persist even after the infection has been controlled or cleared. The damage caused by inflammation, can itself act to perpetuate the inflammatory response. The latent membrane protein 1 (LMP1) of EBV is a pro-inflammatory factor and in the skin of transgenic mice causes a phenotype of hyperplasia with chronic inflammation of increasing severity, which can progress to pre-malignant and malignant lesions...

Employment discrimination causes problems at the labor market, and is hard to combat. Can increasing the degree of structure when selecting applicants increase fairness? Students were asked to perform a computerized selection task and were either provided with tools for systematizing information about the applicants (structured selection) or no such tools (unstructured selection). We hypothesized and found that a structured process, where employing recruitment tools rather than the recruiter's impressionistic judgment is key, improves the ability to identify job-relevant criteria and hence selecting more qualified applicants, even when in-group favoritism is tempting (e...

BACKGROUND: Iron deficiency (ID) may impair long-term neurological development when it occurs in young infants. In cohort studies, it is sometimes necessary to evaluate ID with sera kept frozen for several years. To assess ID, learned societies recommend measuring serum ferritin (SF) level combined with C-reactive protein level. The long-term stability of C-reactive protein in frozen samples is well established but not ferritin. METHODS: We measured SF level (immunoturbidimetric assay; in micrograms per liter) immediately after collection from 53 young adults recruited and followed-up in Porto, Portugal, from 2011 to 2013 (SF1), and then, in 2016 in two aliquots kept frozen at- 80°C for 3 to 5 years: one without (SF2A) and one with (SF2B) intermediate thawing in 2014...

Familial hypercholesterolemia (FH) is an inherited disorder characterized by elevation of serum cholesterol bound to low-density lipoprotein. Mutations in LDLR are the major factors responsible for FH. In this study, we recruited a four-generation Chinese family with FH and identified the clinical features of hypercholesterolemia. All affected individuals shared a novel indel mutation (c.1885_1889delinsGATCATCAACC) in exon 13 of LDLR. The mutation segregated with the hypercholesterolemia phenotype in the family...

BACKGROUND: Giardia intestinalis is a non-invasive protozoan parasite that causes giardiasis in humans, the most common form of parasite-induced diarrhea. Disease mechanisms are not completely defined and very few virulence factors are known. METHODOLOGY: To identify putative virulence factors and elucidate mechanistic pathways leading to disease, we have used proteomics to identify the major excretory-secretory products (ESPs) when Giardia trophozoites of WB and GS isolates (assemblages A and B, respectively) interact with intestinal epithelial cells (IECs) in vitro...

Robust DNA double strand break (DSB) repair and stabilized telomeres help maintain genome integrity, preventing the onset of aging or tumorigenesis. POT1 is one of the six factors in the shelterin complex, which protects telomeres from being recognized as DNA damages. TRF1 and TRF2, two other shelterin proteins, have been shown to participate in DNA DSB repair at non-telomeric regions, but whether POT1, which binds to single strand telomeric DNA at chromosomal ends, is involved in DNA DSB repair has not been assessed...
