Background: Much research has focused on stress related to deployments; however, a substantial proportion of soldiers never deploy. In a study of 1.3 million veterans, suicide risk was higher among veterans who had never deployed. Thus, not being deployed may have an impact on soldiers' well-being; however, no measures exist to assess emotions regarding non-deployment. We aimed to develop and test an original measure of non-deployment emotions. Methods: We examined the Non-Deployment Emotions (NDE) questionnaire, a novel four-item measure of guilt, unit value, unit camaraderie, and unit connectedness in a sample of never-deployed male and female US Army Reserve/National Guard (USAR/NG) soldiers (N = 174)...

BACKGROUND: Universities' responsibility to ensure academic integrity is frustrated by software and communication tools that facilitate content reuse coupled with a growing international essay writing economy. A wide range of behaviours constitute academic dishonesty and while a complex phenomenon to examine, existing evidence suggests that there is sufficient proliferation (both in volume and variety) of these behaviours among Australian university students to warrant concern. This proliferation presents faculty and staff with new challenges in ensuring academic integrity...

PURPOSE: Magnetic resonance spectroscopic imaging (MRSI), under low-spatial resolution settings, often suffers signal contamination from neighboring voxels due to ringing artifacts. Spatial localization can be improved by constraining the point-spread-function (PSF). Here the effectiveness of the two-dimensional PSF-Choice technique in providing improved spatial localization for MRSI is demonstrated. THEORY AND METHODS: The PSF-Choice technique constrains the PSF to a desired shape by manipulating the weighting of RF excitation pulse throughout phase-encode steps...

BACKGROUND: Gait modification is a treatment approach often used for a variety of neuromuscular and musculoskeletal pathologies. Gait modification is commonly applied to a single limb, as is done with foot rotation (FR) in people with knee osteoarthritis (KOA). However, the extent to which gait changes observed in the trained limb are also exhibited in the untrained, contralateral limb during a training session is unknown. RESEARCH QUESTION: The purpose of this study was to examine the within-limb FR differences across four unilateral FR modifications compared to natural walking...

Studies demonstrate that first-year university students are at high risk for weight gain. These reports typically rely on self-selected participants. The purpose of this study was to explore if students who chose to participate in a health-based research study had more desirable health measures and behaviors than students who completed health assessments as part of a first-year seminar course. Health measures included blood pressure (BP), body mass index (BMI), and percent body fat. Health behaviors included dietary patterns (Starting the Conversation questionnaire) and alcohol use (Alcohol Use Disorders Identification Test-Consumption)...

INTRODUCTION: HIV-1-infected men who have sex with men (MSM) more often experience sexual dysfunctions than the general population. We assessed associations between HIV-1 status and decreased sexual functioning among MSM. METHODS: We used cross-sectional data from 399 HIV-1-infected MSM mostly on combination antiretroviral therapy (cART) and 366 HIV-1-uninfected MSM aged ≥45 years participating in the AGEhIV Cohort Study. The study questionnaire included questions on erectile function, sexual satisfaction, and sexual desire...

Priapism is characterized by persistent penile erection in the absence of sexual arousal or desire that does not subside with orgasm. Although relatively uncommon, it is a genitourinary emergency that necessities prompt work-up and appropriate management, as there is a time-dependent relationship between total duration of erection and an increasing risk of permanent erectile dysfunction. Confirming the type of priapism is key to proper management, but the majority of cases presenting to the emergency department are ischemic in nature...

Phototoxicity occurs when UV irradiation causes otherwise benign compounds to become irritant, sensitizers or even genotoxic. This toxicity is particularly a concern after topical application and in dermatological programs where skin irritation can be incompatible with the desired therapeutic outcome. This brief article establishes that the intrinsic Property Forecast Index (iPFI) can be used to evaluate the probability of a compound being phototoxic and gives medicinal chemists a practical tool to handle this liability...

A novel synthetic methodology for the preparation of 1,3-disubstituted pyrazoles from in situ generated nitrile imines and acetylene is reported. The reactions are performed in a simple two-chamber reactor. One part of the reactor is loaded with hydrazonoyl chloride precursors of active nitrile imine species and a base. The other part is used to generate acetylene from CaC2 and water. Partitioning of the reactants improves the yields of desired pyrazoles up to 99% and simplifies their isolation to a simple procedure of solvent evaporation...

The propulsion of micro- and nanoparticles using ultrasound is an attractive strategy for the remote manipulation of colloidal matter using biocompatible energy inputs. However, the physical mechanisms underlying acoustic propulsion are poorly understood, and our ability to transduce acoustic energy into different types of particle motions remains limited. Here, we show that the three-dimensional shape of a colloidal particle can be rationally engineered to direct desired particle motions powered by ultrasound...

A high throughput synthesis method of graphene has been required for a long time to apply graphene to industrial applications. Of the various synthesis methods, the chemical exfoliation of graphite via graphene oxide (GO) is advantageous as far as productivity is concerned; however, the quality of the graphene produced by this method is far inferior to that synthesized by other methods, such as chemical vapor deposition on metals. Developing an effective reduction and restoration method for GO on dielectric substrates has been therefore a key issue...

BACKGROUND: In order to optimize outcomes of novel therapies for cerebellar ataxias (CAs), it is desirable to start these therapies while declined functions are restorable: i.e. while the so-called cerebellar reserve remains. OBJECTIVE: In this mini-review, we tried to define and discuss the cerebellar reserve from physiological and morphological points of view. METHOD: The cerebellar neuron circuitry is designed to generate spatiotemporally organized outputs, regardless of the region...

The Completeness of Revascularization in patients with multivessel coronary artery disease (CAD) remains an unanswered question. Despite 20 years of investigation there are still major doubts in this topic, reaching as far as to the lack of a standardized definition. The employment of different definition and the multiplicity of confounding variables that in general favor patients who receive a complete revascularization (CR) are the reason of difficult comparisons between studies. The complexity of coronary anatomy diseases and the clinical features play important role in the revascularization strategy...

PURPOSE: The standard clinical treatment of Twin-to-Twin transfusion syndrome consists in the photo-coagulation of undesired anastomoses located on the placenta which are responsible to a blood transfer between the two twins. While being the standard of care procedure, fetoscopy suffers from a limited field-of-view of the placenta resulting in missed anastomoses. To facilitate the task of the clinician, building a global map of the placenta providing a larger overview of the vascular network is highly desired...

In recent years, the joint models have been widely used for modeling the longitudinal and time-to-event data simultaneously. In this study, we proposed an approach (PA) to study the longitudinal and survival outcomes simultaneously in heterogeneous populations. PA relaxes the assumption of conditional independence (CI). We also compared PA with joint latent class model (JLCM) and separate approach (SA) for various sample sizes (150, 300, and 600) and different association parameters (0, 0.2, and 0.5). The average bias of parameters estimation (AB-PE), average SE of parameters estimation (ASE-PE), and coverage probability of the 95% confidence interval (CP) among the three approaches were compared...
