Results from dyadic analyses indicated that holding back was associated with decreases in one's own marital sati...

Evaluation of Skeletal and Dental Effects of Lower Lingual Arches.

A lower lingual arch is usually recommended as a holding device to maintain arch length and to prevent mesial migration of the mandibular first molars. Despite its widespread use, comparatively little is known about the effects of a lower lingual holding arch on preservation of lower arch dimensions and tooth position and the impact of the device on mandibular growth. The aim of this study is to evaluate the skeletal and dental effects of the lower lingual holding arch with regard to arch dimension, positio...


Lamivudine monotherapy as a holding regimen for HIV-positive children.

In resource-limited settings holding regimens, such as lamivudine monotherapy (LM), are used to manage HIV-positive children failing combination antiretroviral therapy (cART) to mitigate the risk of drug resistance developing, whilst adherence barriers are addressed or when access to second- or third-line regimens is restricted. We aimed to investigate characteristics of children placed on LM and their outcomes.

Motor experience with a sport-specific implement affects motor imagery.

The present study tested whether sport-specific implements facilitate motor imagery, whereas nonspecific implements disrupt motor imagery. We asked a group of basketball players (experts) and a group of healthy controls (novices) to physically perform (motor execution) and mentally simulate (motor imagery) basketball throws. Subjects produced motor imagery when they were holding a basketball, a volleyball, or nothing. Motor imagery performance was measured by temporal congruence, which is the correspondence...

Effects of protein oxidation on the texture and water-holding of meat: A review.

Protein oxidation readily occurs in post-mortem muscle during storage and processing. Over the past decade new analytical methods have been developed and new aspects of protein oxidation in meat have been studied, such as the reaction mechanism, and impacts on eating quality and nutritional value. It is now evident that amino acid side chains in myofibrillar proteins undergoes modifications due to oxidative stress. In turn this will lead to formation of new protein-protein cross-links in structural proteins...

The effect of municipal treated wastewater on the water holding properties of a clayey, calcareous soil.

Wastewater reuse is a practice that has been gaining attention for the past few decades as the world's population rises and water resources become scarce. Wastewater application on soil can affect soil health, and the manner and extent to which this occurs depends heavily on soil type and water quality. This study compared the long-term (15+ years) effects and suitability of using secondary-level treated municipal wastewater and brackish groundwater for irrigation on the water holding capacity of a clayey, ...

Location, seasonal, and functional characteristics of water holding containers with juvenile and pupalAedes aegypti in Southern Taiwan: A cross-sectional study using hurdle model analyses.

Aedes aegypti carries several viruses of public health importance, including the dengue virus. Dengue is the most rapidly spreading mosquito-borne viral disease in the world. Prevention and control of dengue mainly rely on mosquito control as there is no antiviral treatment or a WHO-approved vaccine. To reduce the Ae. aegypti population, studying the characteristics of their habitats is necessary. Aedes aegypti prefer breeding in artificial water holding containers in peridomestic or domestic settings. Thei...

An Innovative and Easy Dome Holding Technique for Transdomal Suture in Rhinoplasty.

Suture tip plasty is one the most used methods in nasal tip surgery. Transdomal suture (TDS) used for this purpose is utilized for providing the dome symmetry, thinning the nasal tip, and enhancing the nasal tip projection and rotation. However, there are not sufficient visual data on what the dome position should be during TDS. In this study, it was aimed to be directive in tip plasty and to define the convenient dome holding technique during TDS. Patients, 510 male and 621 female at the age of 18 to 50 ye...

The experimental results showed that graphite can be oxidized, and forms epoxy groups most easily, followed by hydroxyl and carboxyl groups. The prepared graphene oxide forms a membrane-state as a single layer structure, with an irregular surf...

Associations Between Past-Month Pain and Distress Intolerance Among Daily Cigarette Smokers.

A growing body of research indicates that pain is associated with the maintenance of tobacco smoking. Distress intolerance (DI) may play an important role in the link between pain and smoking. The goal of this study was to examine the association between past-month pain status and DI among a sample of daily cigarette smokers. It was hypothesized that smokers who reported past-month pain (vs. those reporting no past-month pain) would have higher perceived DI (i.e., lower scores on the Distress Tolerance Scal...

In situ Active Poling of Nanofibers Network for Gigantically Enhanced Particulate Filtration.

Enhancing the filtration efficiency of air filtering material without increasing its airflow resistance is of major challenge and of great significance. In this work, we report a type of active-poled nanofibers onto which in situ active poling is applied. It results in significantly enhanced filtration efficiency as well as dust holding capacity while keeping the airflow resistance constant. Owing to the in situ applied electric field, the nanofibers as well as the particulates are polarized. As a result, a...

The home handedness questionnaire: pilot data from preschoolers.

While handedness questionnaires are widely used in adults, there is no comparable measure designed specifically for children. The current study developed the Home Handedness Questionnaire (HHQ), a new measure for preschoolers administered by parents using common household items. The HHQ has two scales that distinguish action types typically combined on other measures: actions performed with only the right or left hand (i.e., unimanual, such as holding a toothbrush), and actions performed with one hand holdi...

Geometric Effects of Colloidal Particles on Stochastic Interface Adsorption.

The stochastic interface adsorption behaviors of ellipsoid particles were investigated using optical laser tweezers. The particles were brought close to the oil-water interface, attempting to attach forcefully to the interface. Multiple attempts of the particle attachments statistically quantified the dependence of the adsorption probability on the particle aspect ratio. It was found that the adsorption probability proportionally increased with the aspect ratio due to the decrease in electrostatic interacti...
