PRIMARY OBJECTIVE: To investigate the neural substrates of visual memory in a sample of patients with traumatic brain injury (TBI). We hypothesized that patients with decreased grey and white matter volume in frontal and parietal cortices as well as medial temporal and occipital lobes would perform poorly on the tests of visual memory analysed. METHODS AND PROCEDURES: 39 patients and 53 controls were assessed on tests of visual memory and learning from the Cambridge Neuropsychological Test Automated Battery (CANTAB)...

BACKGROUND: Alcohol use among underage youth is a significant public health concern. According to the National Institute on Alcohol Abuse and Alcoholism, alcohol is the "drug of choice" among adolescents, meaning more youth use and abuse alcohol than any other substance. Prevalence of alcohol use is disproportionately higher among sexual minority youth (SMY) than among their heterosexual peers. We examined sexual identity and sexual behavior disparities in alcohol use, and the mediational role of bullying in a sample of high school students...

INTRODUCTION: Cross-sectional research has found that young men who have sex with men (YMSM) are more likely to engage in heavy drinking and to have higher rates of marijuana and other illicit drug use compared to their heterosexual peers, but considerably less is known about their patterns of substance use over time. METHODS: In this study, we combined two longitudinal samples of racially diverse YMSM (N=552) and modeled their substance use trajectories from late-adolescence to young adulthood, including their frequency of alcohol use, frequency of marijuana use, and poly-drug use, using piecewise latent curve growth modeling to model change from ages 17-21 and change from ages 22-24...

OBJECTIVE: The aim of this study was to compare anatomic results after vaginal uterosacral ligament suspension with absorbable versus permanent suture. METHODS: We performed a retrospective cohort study of women who underwent vaginal uterosacral ligament suspension, from 2006 to 2015. We compared 2 groups: (1) absorbable suspension suture and (2) permanent suspension suture (even if accompanied by absorbable suture). Our primary outcome was composite anatomic failure defined as (1) recurrent prolapse in any compartment past the hymen or (2) retreatment for prolapse...

BACKGROUND: In naturally occurring numbers the frequencies of digits 1-9 in the leading position are counterintuitively distributed because the frequencies of occurrence are unequal. Benford-Newcomb's law describes the expected distribution of these frequencies. It was previously shown that known fraudulent articles consistently violated this law. OBJECTIVE: To compare the features of 12 known fraudulent articles from a single Japanese author to the features of 13 articles in the same research field from other Japanese authors, published during the same time period and identified with a Medline database search...

Water within and surrounding the structure of a biological system adopts context-specific dynamics that mediate virtually all of the events involved in the inner workings of a cell. These events range from protein folding and molecular recognition to the formation of hierarchical structures. Water dynamics are mediated by the chemistry and geometry of interfaces where water and biomolecules meet. Here we investigate experimentally and computationally the translational dynamics of vicinal water molecules within the volume of a supramolecular peptide nanofiber measuring 6...

INTRODUCTION: The goal of burn care is that 'the quality of the outcome must be worth the pain of survival'. More research is needed to understand how best to deliver care for patients with burns to achieve this aim. Loss of independence, function as well as loss of income for patients with burns and carers cause a significant burden at both individual and societal levels. Much is being done to advance knowledge in the clinical care field; however, there has been a paucity of research exploring psychosocial outcomes...

Purpose Regular use of aspirin is associated with improved survival for patients with colorectal cancer (CRC). However, the timing of and the subtype of CRC that would benefit the most from using aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) in relation to survival is unclear. Patients and Methods In all, 2,419 patients age 18 to 74 years with incident invasive CRC who were diagnosed from 1997 to 2008 were identified from population-based cancer registries in the United States, Canada, and Australia...

Many viruses migrate between different cellular compartments for successive stages of assembly. The HSV-1 capsid assembles in the nucleus and then transfers into the cytoplasm. First, the capsid buds through the inner nuclear membrane, becoming coated with nuclear egress complex (NEC) protein. This yields a primary enveloped virion (PEV) whose envelope fuses with the outer nuclear membrane, releasing the capsid into the cytoplasm. We investigated the associated molecular mechanisms by isolating PEVs from US3-null-infected cells and imaging them by cryo-electron microscopy and tomography...

Animals are frequently used for the development and testing of new hearing devices. Dimensions of the middle ear and cochlea differ significantly between humans and commonly used animals, such as rodents or cats. The sheep cochlea is anatomically more like the human cochlea in size and number of turns. This study investigated the middle-ear ossicular velocities and intracochlear sound pressure (ICSP) in sheep temporal bones, with the aim of characterizing the sheep as an experimental model for implantable hearing devices...

The appropriate orchestration of different arms of the immune response is critical during viral infection to promote efficient viral clearance while limiting immunopathology. However, the signals and mechanisms that guide this coordination are not fully understood. IFNs are produced at high levels during viral infection and have convergent signaling through STAT1. We hypothesized that STAT1 signaling during viral infection regulates the balance of innate lymphoid cells (ILC), a diverse class of lymphocytes that are poised to respond to environmental insults including viral infections with the potential for both antiviral or immunopathologic functions...

Findings from epidemiological studies have found that physical activity (PA) is associated with a lower risk of colorectal cancer (CRC). Recent studies have found an increased CRC risk with higher sitting time (ST); however, many studies did not include PA as a potential confounder. The objective of this project was to investigate the independent and combined associations of ST and PA with the risk of incident CRC, specifically colon and rectal cancer. Participants in the Women's Health Initiative Observational Study (n=74 870), 50-79 years of age self-reported ST and PA at baseline, years 3 and 6...

BACKGROUND/AIM: The safety of amateur and professional boxing is a contentious issue. We hypothesised that advanced magnetic resonance imaging and neuropsychological testing could provide evidence of acute and early brain injury in amateur boxers. METHODS: We recruited 30 participants from a university amateur boxing club in a prospective cohort study. Magnetic resonance imaging (MRI) and neuropsychological testing was performed at three time points: prior to starting training; within 48 h following a first major competition to detect acute brain injury; and one year follow-up...

Knowledge about the transmission, prevention, and treatment of HIV remains a critical element in psychosocial models of HIV risk behavior and is commonly used as an outcome in HIV prevention interventions. However, most HIV knowledge questions have not undergone rigorous psychometric testing such as using item response theory. The current study used data from six studies of men who have sex with men (MSM; n = 3565) to (1) examine the item properties of HIV knowledge questions, (2) test for differential item functioning on commonly studied characteristics (i...
