Female phlebotomine sand flies (Diptera: Psychodidae) transmit leishmaniasis as they engorge on vertebrate blood required for egg production. Phlebotomus (Phlebotomus) papatasi (Scopoli, 1786), the vector of Leishmania major (Yakimoff & Schokhor, 1914), the causative agent of cutaneous leishmaniasis (CL) were not attracted to large horizontal sticky traps (LHSTs) unless these ...

Commercial poultry production management practices have been under increased public scrutiny driven by concerns for food safety and animal welfare. Within the United States, wood shavings and raised plastic floors are common flooring systems used in duck production. It is intuitive that each flooring type would present different management challenges ...

Mulch preferences of the Asian cockroach, Blattella asahinai Mizukubo, were determined in a series of laboratory experiments. Because this species is a peridomestic pest, mulch preferences may be a key part of an integrated pest management program for homeowners. Five mulches were used: cypress, oak leaf litter, pine straw, rubber, ...

Ageing on lees involves ageing the wine in contact with yeast cells after fermentation. If combined with the addition of oak chips, it can soften the wood flavour and increase the aromatic complexity of wine. The aim of the present work is to optimise both ageing techniques through selection of ...

We investigate the consequences of population aging for long-run economic growth perspectives. Our framework incorporates endogenous growth models and semi-endogenous growth models as special cases. We show that (1) increases in longevity have a positive impact on per capita output growth, (2) decreases in fertility have a negative impact on ...

Productive vocabulary was measured every four months in 16- to 28-months-olds. Attainment of motor-milestones was also measured. An earlier age of sitting and walking predicted a higher intercept and a larger slope (growth) of productive vocabulary respectively, suggesting that attainment of walking propels linguistic development.

PATIENTS ...

The population of the world is aging. A greater proportion of older people are retaining increasing numbers of natural teeth. Aging is associated with changes in oral architecture and muscle weakness, making personal oral hygiene more difficult, particularly for the oldest and most frail individuals. Furthermore, there is exposure of ...

This study evaluated the interaction between medium voltage electrical stimulation, SmartStretch™ stretching and ageing treatments on key meat quality traits of hot boned sheep m. semimembranosus. Medium voltage stimulation reduced initial pH (P<0.001), but did not impact on other meat quality traits. There was a significant interaction between stretch treatment ...

Adolescence is a relatively short period between childhood and adulthood. It is very difficult to determine adulthood based on biological indicators.

AgI is instable under light irradiation owing to its photosensitive properties, while a supported Ag-AgI composite has been demonstrated to be a stable photocatalyst. However, seldom investigations have been focused on the photocatalytic activity (including deactivation) and photoinduced stability of the photosensitive AgI materials. In this study, the AgI nanoparticles ...

Multipotent postnatal stem cells can be isolated from human periodontal ligaments (PDLs) and have the potential for large-scale expansion, offering a reliable cell source for clinical use in periodontal regenerative therapies. However, the effects of aging on the mesenchymal stem cell (MSC) properties of these cells remain undefined. The aims ...

Nomograms to predict normal aortic root diameter for body surface area (BSA) in broad ranges of age have been widely used but are limited by lack of consideration of gender effects, jumps in upper limits of aortic diameter among age strata, and data from older teenagers. Sinus of Valsalva diameter ...

There are conflicting reports in the past literature documenting the tendency of anemia in patients with periodontitis. Hence, this study was undertaken to assess whether periodontitis may cause an anemic state, by evaluating and comparing the red blood cell count, levels of hemoglobin, hematocrit, erythrocyte sedimentation rate (ESR), serum iron ...

Treatment of impacted maxillary canines frequently requires surgical intervention, which can involve substantial complications. Thus, it is desirable to identify a reliable method for the early diagnosis of canine displacement. In this study, we sought to determine whether impaction of a maxillary canine can be predicted using measurements made on ...

The formation and atom distribution in two-dimensional Pd(x)Ag(1-x)/Pd(111) monolayer surface alloys were studied by high resolution scanning tunnelling microscopy (STM) with chemical contrast. From short-range order (SRO) parameters, we calculate preferences for like or unlike nearest neighbours to elucidate the mixing behaviour of the two components for various sub monolayer ...
