BACKGROUND: The success of an area-wide sterile insect technique (SIT) programme against Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) relies on the mating success of sterile males in the field. Limited information is available about the effectiveness of sterile males in achieving mates with wild females and how these matings contribute to ...

The experience of positive affect is essential for healthy functioning and quality of life. Although there is a great deal of research on ways in which people regulate negative states, little is known about the regulation of positive states. In the present study we examined age differences in the types ...

Pathogenic mutations of the APP gene, leading to early-onset Alzheimer's disease (AD) have been known for more than 20 years. Recently, it was discovered that APP mutations might also be protective. A rare variant A673T reportedly protects against AD and age-related cognitive impairment and might functionally inhibit proteolytic cleavage at ...

Nitric oxide synthase-1 (NOS1) is involved in several forms of plasticity including hippocampal-dependent learning and memory, experience-dependent plasticity in the barrel cortex, and long-term potentiation (LTP) in the hippocampus and neocortex. NOS1 also contributes to ischemic damage during stroke and has a stronger deleterious effect in males than females. We ...

Vocal duetting occurs in many taxa, but its function remains much-debated. Like species in which only one sex sings, duetting birds can use their song repertoires to signal aggression by singing song types that match those of territorial intruders. However, when pairs do not share specific combinations of songs (duet ...

Aging is one of the best, but rarely referred, risk factors for various types of cancer including lung cancer, because age could be a surrogate for accumulation of genetic events in cancers. Smoking inversely associates with the presence of epidermal growth factor receptor (EGFR) mutation in lung cancer, but its ...

Vitamin D deficiency is a serious global issue. Although the serum 25-hydroxyvitamin D [25(OH)D] test is generally the most accurate way to assess vitamin D levels, the optimal range of 25(OH)D has yet to be established. Moreover, the optimal level may vary according to race, region, and age. Suboptimal vitamin ...

We have previously shown that aging is associated with weakened rat mesenteric lymphatic vessel (MLV) contractility. However, the specific mechanisms contributing to this aging-associated contractile degeneration remain unknown. Aging is often associated with elevations in oxidative stress, and reactive oxygen species (ROS) have been shown to reduce the contractility of ...
