aging coefficient (ac) or aged-child ratio or age composition; takes into account the numbers and areas at both ends of the age distribution simultaneously. ac is the total number of individuals aged 65 years and more, divided by the total number of individuals aged 14 years, multiplied by 100. herein, age composition in iranian popu1ations, according to different provinces, place of residence ...

Influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. High germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...

The aim of the research was to evaluate influence year and seed lots on most important indicators cabbage quality. Quality testing nine different Potomac F1 performed during three years (2019, 2020 2021). Analyses variance showed a significant effect (p<0.01) (Y), while lot (L) their interaction (Y × L) (p<0.05) all observed parameters quality (germination energy, total germination, abnor...

This study was performed in order to evaluate the effects of irrigation and application of Zn fertilizer on  seed storage proteins  in chickpea, Azad cultivar. Experiment was performed in an factorial using randomized complete block design with three replications. In this experiment, two factor consist of irrigation in three levels (I1= non irrigation and I2= irrigation in...

BACKGROUND Skin aging is a natural process that may be aggravated by environmental factors. Topical products are the conventional means to combat aging; however, the use of oral supplements is on the rise to assist in the management of aged skin. OBJECTIVE The purpose of this study was to assess the effects and safety of an oral supplement containing (per tablet) marine protein (105 mg), vita...

Previous neuroimaging studies have suggested that cerebral changes over normal aging are not simply characterized by regional alterations, but rather by the reorganization of cortical connectivity patterns. The investigation of structural covariance networks (SCNs) using voxel-based morphometry is an advanced approach to examining the pattern of covariance in gray matter (GM) volumes among diff...

Seed storage proteins are synthesized as sources of carbon, nitrogen and sulfur for the next generation of plants. Reactive oxygen species serve as second messengers for signal transduction; however, molecular targets of oxidant signaling have not been defined. Here, many researchers showes that ligand–receptor mediated signaling promotes reactive oxygen species– dependent protein carbonylation...
