Manganese is an essential nutrient that may play a role in the production of inflammatory biomarkers. We examined associations between estimated dietary manganese intake from food/beverages and supplements with circulating biomarkers of inflammation. We further explored whether estimated dietary manganese intake affects DNA methylation of selected genes involved in the production of these biomarkers. We analyzed 1023 repeated measures of estimated dietary manganese intakes and circulating blood inflammatory biomarkers from 633 participants in the Normative Aging Study...

Since it was first characterised in 1983, 2-acetyl-1-pyrroline (2AP) has been considered to be the most important aroma compound in rice. In this study, we show four other amine heterocycles: 6-methyl, 5-oxo-2,3,4,5-tetrahydropyridine (6M5OTP), 2-acetylpyrrole, pyrrole and 1-pyrroline, that correlate strongly with the production of 2AP, and are present in consistent proportions in a set of elite aromatic rice varieties from South East Asia and Australia as well as in a collection of recombinant inbred lines (RILs) derived from indica Jasmine-type varieties, Australian long grain varieties (temperate japonica) and Basmati-type rice (Grp V)...

Mechanical loading is necessary for the development and maintenance of the musculoskeletal system. Removal of loading via microgravity, paralysis, or bed rest leads to rapid loss of muscle mass and function; however, the molecular mechanisms that lead to these changes are largely unknown, particularly for the spaceflight (SF) microgravity environment. Furthermore, few studies have explored these effects on the shoulder, a dynamically stabilized joint with a large range of motion; therefore, we examined the effects of microgravity on mouse shoulder muscles for the 15-d Space Transportation System (STS)-131, 13-d STS-135, and 30-d Bion-M1 missions...

Previous studies on taste acceptance have been conducted taste-by-taste and with a cross-sectional design. The aim of this study was to longitudinally evaluate the acceptance of sweet, salty, bitter, sour and umami solutions, and a fat emulsion comparatively in a birth cohort from 3 to 20 months old. The acceptance of each taste relative to water was defined using proportional variables that are based on ingestion (IR) or liking evaluated by the experimenter (LR). These data were analyzed with mixed models that accounted for age and subject effects (minimum 152 observations/age/taste; maximum 216)...

OBJECTIVE Translabyrinthine resection is one of a number of treatment options available to patients with vestibular schwannomas. Though this procedure is hearing destructive, the authors have noted excellent clinical outcomes for patients with small tumors. The authors review their experience at a tertiary acoustic neuroma referral center in using the translabyrinthine approach to resect small vestibular schwannomas. All operations were performed by a surgical team consisting of a single neurosurgeon and 1 of 7 neurotologists...

OBJECTIVE: One of four American cancer patients dies of lung cancer. Environmental factors such as tobacco smoking are known to affect lung cancer risk. However, there is a genetic factor to lung cancer risk as well. Here, we perform parametric linkage analysis on family-based genotype data in an effort to find genetic loci linked to the disease. METHODS: 197 individuals from families with a high-risk history of lung cancer were recruited and genotyped using an Illumina array...

Father support of young people living in out-of-home settings is a neglected area of research. The study examines the moderating role of peer victimization in the association between father support and adjustment difficulties among male and female adolescents in residential care settings. Using random cluster sampling, the study includes the reports of 1,409 young people, in Grades 8 to 12, residing in 16 Israeli educational residential care settings designed for youth from underprivileged backgrounds. The findings show that, on average, fathers are highly involved in these young people's lives...

BACKGROUND AND OBJECTIVES: Prematurity, a strong risk factor for sudden unexpected infant death (SUID), was addressed in recommendations by the American Academy of Pediatrics in 2011 for safe sleep education in NICUs. We documented associations between gestational age (GA) and SUID subsequent to these guidelines. METHODS: Using the 2012-2013 US linked infant birth and death certificate period files, we documented rates per live births of sudden infant death syndrome, ill-defined and unspecified causes, accidental suffocation and strangulation in bed, and overall SUID by GA in postneonatal, out-of-hospital, and autopsied cases; compared survivors and cases; and estimated logistic regression models of associations between GA and SUID...

HIV-1 poorly infects monocyte-derived dendritic cells (MDDCs). This is in a large part due to SAMHD1, which restricts viral reverse transcription. Pseudotyping HIV-1 with VSV-G strongly enhances infection, suggesting that earlier steps of viral replication, including fusion, are also inefficient in MDDCs. The site of HIV-1 fusion remains controversial and may depend on the cell type, with reports indicating that it occurs at the plasma membrane or contrarily, in an endocytic compartment. Here, we examined the pathways of HIV-1 entry in MDDCs...

The development of many sporadic cancers is directly initiated by carcinogen exposure. Carcinogens induce malignancies by creating DNA lesions (i.e., adducts) that can result in mutations if left unrepaired. Despite this knowledge, there has been remarkably little investigation into the regulation of susceptibility to acquire DNA lesions. In this study, we present the first quantitative human genome-wide map of DNA lesions induced by ultraviolet (UV) radiation, the ubiquitous carcinogen in sunlight that causes skin cancer...

AIM: Nitromethane, found in fuels used for short distance racing, model cars, and model airplanes, produces a falsely elevated serum creatinine with standard creatinine analysis via the Jaffé method. Erroneous creatinine elevation often triggers extensive testing, leads to inaccurate diagnoses, and delayed or inappropriate medical interventions. Multiple reports in the literature identify "enzymatic assays" as an alternative method to detect the true value of creatinine, but this ambiguity does not help providers translate what type of enzymatic assay testing can be done in real time to determine if there is indeed false elevation...

INTRODUCTION: Medical educators have been concerned that medical students may decline in empathy for patients during the course of their training, based on studies measuring clinical empathy using psychometrically strong self-report measures. Clinical empathy is a complex construct, incorporating attitudes toward patients but also other components, such as professional detachment. Triangulation of extant measures with instruments based on nonreactive methods could provide a better understanding of whether and how physician attitudes toward patients may be changing during training...

Gaucher disease (GD) is caused by mutations on the GBA1 gene leading to deficiency in acid β-glucosidase (GCase) and subsequent accumulation of its substrates, glucosylceramide (GlcC) and glucosylsphingosine (GlcS). GlcS in plasma has been proposed as a highly sensitive and specific biomarker for the diagnosis of GD and for monitoring disease progression and response to therapy. Here we report a novel robust and accurate hydrophilic interaction liquid chromatography tandem mass spectrometric method (HILIC-MS/MS) for the direct measurement of glucosylsphingosine (GlcS) in dried plasma spots (DPS)...

A significant number of U.S. health sciences libraries have closed since the mid-1990's. A pilot study was conducted with academic physicians to understand the impact of closing the health sciences library in the teaching hospital with which they were affiliated. A brief survey was designed and distributed to fourteen faculty members with thirteen useable responses received. The study elicited a context-sensitive perspective on the closing of the library with the most noteworthy outcome being the additional time required by attending physicians and trainees to perform the work that previously was performed by library staff...

BACKGROUND: The availability of minimal access instrumentation and endoscopic visualization has revolutionized the field of minimally invasive skull base surgery. The transorbital endoscopic approach using an eyelid incision has been proposed as a new minimally invasive technique for the treatment of skull base pathology, mostly extradural tumors. Our study aims to evaluate the anatomical aspects and potential role of the transorbital endoscopic approach for exposure of the sylvian fissure, middle cerebral artery and crural cistern...

Genomic imprinting involves a DNA methylation-dependent and parent-of-origin-specific regulation of gene expression. Clinical assays for imprinting disorders are genomic locus-, disorder-, and molecular defect-specific. We aimed to clinically validate a genome-wide approach for simultaneous testing of common imprinting disorders in a single assay. Using genome-wide DNA methylation arrays, epigenetic profiles from peripheral blood of patients with Angelman, Prader-Willi, Beckwith-Wiedemann, and Silver-Russell syndrome were compared to a reference cohort of 361 unaffected individuals...
