BACKGROUND: Recent studies have demonstrated that pterygium has a close relationship with dry eye disease. This study is to determine abnormalities in meibomian gland and tear function in patients with pterygium and to assess the relationship between the variables. MATERIALS AND METHODS: Forty eyes from forty patients with primary nasal pterygium and forty eyes from forty volunteers without ocular pathologies were enrolled in this study. Ocular surface disease index scores, meibomian gland expression scores, lid margin abnormality scores, meiboscore, tear film breakup time (BUT), Schirmer test (SIT) value, and the lower tear meniscus height (TMH), tear meniscus depth (TMD), and tear meniscus area (TMA) using Fourier domain optical coherence were performed...

BACKGROUND: Insulin is generally administered to people with type 1 diabetes mellitus (T1DM) using multiple daily injections (MDIs), but can also be delivered using infusion pumps. In the UK, pumps are recommended for patients with the greatest need and adult use is less than in comparable countries. Previous trials have been small, of short duration and have failed to control for training in insulin adjustment. OBJECTIVE: To assess the clinical effectiveness and cost-effectiveness of pump therapy compared with MDI for adults with T1DM, with both groups receiving equivalent structured training in flexible insulin therapy...

Sitting for long periods of time, both during work and leisure times, is the typical behavior of the modern society. Especially at work, where there is not much flexibility, adopting the sitting posture for the entire day can cause some short- and long-term effects. As workers' productivity and well-being relies on working conditions, evaluating the effects caused by the work postures assumes a very important role. The purpose of this paper was to evaluate the variation of some anthropometric measurement during one typical workday to understand if the known long-term effects, can also be seen and quantified in an 8-hour period...

OBJECTIVE: To report the adaptation and cultural validation of the Oral Health Literacy Instrument (OHLI) for the adult Chilean population attending public and university health services. STUDY DESIGN: The original OHLI in English was translated to Spanish and back-translated, then a preliminary version was obtained following review by four experts. A pilot study was carried out in 30 patients, who were asked to assess their understanding of the questionnaire. The following variables were included: sociodemographic factors (sex, age, average monthly income, education and marital status); oral health (history of caries, periodontal disease and oral hygiene); oral health-related quality of life; health literacy; oral health literacy; and psychometric properties (internal consistency, temporal stability, convergent validity and predictive validity)...

The goal of this study was to describe the contribution of outer hair cells (OHCs) and the auditory nerve (AN) to speech understanding in quiet and in the presence of background noise. Fifty-three human subjects with hearing ranging from normal to moderate sensorineural hearing loss were assayed for both speech in quiet (Word Recognition) and speech in noise (QuickSIN test) performance. Their scores were correlated with OHC function as assessed via distortion product otoacoustic emissions, and AN function as measured by amplitude, latency, and threshold of the VIIIth cranial nerve Compound Action Potential (CAP) recorded during electrocochleography (ECochG)...

Host-microbe interactions are influenced by complex host genetics and environment. Studies across animal taxa have aided our understanding of how intestinal microbiota influence vertebrate development, disease, and physiology. However, traditional mammalian studies can be limited by use of isogenic strains, husbandry constraints that result in small sample sizes and limited statistical power, reliance on indirect characterization of gut microbial communities from fecal samples, and concerns whether observations in artificial conditions are actually reflective of what occurs in the wild...

Efforts to understand the influence of historical global warming on individual extreme climate events have increased over the past decade. However, despite substantial progress, events that are unprecedented in the local observational record remain a persistent challenge. Leveraging observations and a large climate model ensemble, we quantify uncertainty in the influence of global warming on the severity and probability of the historically hottest month, hottest day, driest year, and wettest 5-d period for different areas of the globe...

Many genetic alterations have been identified to aid in understanding the genetic basis of male infertility, however, the cause of 30% of male infertility remains unknown. Some studies indicated that subdeletions of Y chromosome may be a reason for male infertility caused by testicular failure. In this regard, we aimed to investigate frequency of AZFc region subdeletions and their clinical effects in patients with idiopathic infertility. A total of 333 male infertile patients with non-obstructive azoospermia (NOA) or oligoasthenoteratozoospermia (OAT), and 87 normozoospermic controls were screened to detect gr/gr, b1/b3 and b2/b3 subdeletions...

BACKGROUND: Individuals with type 2 diabetes have an increased risk for comorbidities such as heart disease, lower limb amputations, stroke, and renal failure. Multiple factors influence development of complications in a person living with type 2 diabetes; however, an individual's self-management behaviors may delay the onset of, or lessen the severity of, these complications. Social support provides personal, informal advice and knowledge that helps individuals initiate and sustain self-management and adherence...

BACKGROUND: Nurses play a pivotal role in determining the efficiency, effectiveness, and sustainability of health care systems. Nurses' job satisfaction plays an important role in the delivery of quality health care. There is paucity of studies addressing job satisfaction among nurses in the public hospital setting in Ethiopia. Thus, this study aimed to assess job satisfaction and factors influencing it among nurses in Jimma zone public hospitals, southwestern Ethiopia. METHODS: An institution-based census was conducted among 316 nurses working in Jimma zone public hospitals from March to April, 2014...

We demonstrate experimentally that the traditional double random phase encoding (DPRE) technique is vulnerable to the cyphertext-only attack (COA). With the statistical ergodic property of the speckle, we show that the plaintext image can be recovered from the cyphertext alone owing to the fact that their energy spectral density functions are identical. Our result reveals the most serious security issue with the DRPE as it suggests that even the one-time-pad does not guarantee its security. This will open up new inside understanding of current optical security techniques...

Auditioning is at the very center of educational and professional life in music and is associated with significant psychophysical demands. Knowledge of how these demands affect cardiovascular responses to psychosocial pressure is essential for developing strategies to both manage stress and understand optimal performance states. To this end, we recorded the electrocardiograms (ECGs) of 16 musicians (11 violinists and 5 flutists) before and during performances in both low- and high-stress conditions: with no audience and in front of an audition panel, respectively...

David M Holloway, Alexander V Spirov
Anterior-posterior (AP) body segmentation of the fruit fly (Drosophila) is first seen in the 7-stripe spatial expression patterns of the pair-rule genes, which regulate downstream genes determining specific segment identities. Regulation of pair-rule expression has been extensively studied for the even-skipped (eve) gene. Recent live imaging, of a reporter for the 2nd eve stripe, has demonstrated the stochastic nature of this process, with 'bursts' in the number of RNA transcripts being made over time. We developed a stochastic model of the spatial and temporal expression of eve stripe 2 (binding by transcriptional activators (Bicoid and Hunchback proteins) and repressors (Giant and Krüppel proteins), transcriptional initiation and termination; with all rate parameters constrained by features of the experimental data) in order to analyze the noisy experimental time series and test hypotheses for how eve transcription is regulated...

Representational models specify how activity patterns in populations of neurons (or, more generally, in multivariate brain-activity measurements) relate to sensory stimuli, motor responses, or cognitive processes. In an experimental context, representational models can be defined as hypotheses about the distribution of activity profiles across experimental conditions. Currently, three different methods are being used to test such hypotheses: encoding analysis, pattern component modeling (PCM), and representational similarity analysis (RSA)...

Infant mortality is considered a basic measure of public health for countries around the world (1-3). Over the past decade, the overall infant mortality rate in the United States has improved, declining 15% from 6.86 infant deaths per 1,000 live births in 2005-a recent high-to 5.82 in 2014 (4). Over the years, many efforts have been made to understand and lower infant mortality (4,5). This report examines the 2014 linked birth/infant death data from the National Vital Statistics System (NVSS) to describe trends in infant mortality in the United States by race and Hispanic origin, state, and leading causes of infant deaths from 2005 through 2014...

Sleeve gastrectomy operations have become popular among restrictive obesity surgeons, due to its effectiveness for losing weight and acceptable complication rates. However, leakage is a significant problem in these operations. In this ex vivo study, we tried to understand mechanisms of leakage and to examine the effects of two different types of frequently referred reinforcement techniques using sutures. The resected gastric specimens that were removed during sleeve gastrectomy operations were used in this ex vivo study...

OBJECTIVE: The primary objective of this study was to evaluate the effects of different speed control measures on the safety of unsignalized mid-block street crossings. METHODS: In China, it is quite difficult to obtain traffic crash and conflict data for pedestrians using such crossings, mainly due to the lack of traffic data management and organizational issues. In light of this, the proposed method did not rely on such data, but considered vehicle speed, which is a leading contributing factor of pedestrian safety at mid-blocks...
