to study the effects of different levels of seed ageing and bacteria inoculation on yield of common bean at field conditions, an experiment was carried out as factorial arranged in rcbd design with three replications at research farm of university of tehran (karaj-iran) in 2012. treatments consisted of four levels of seed ageing (0 (control), 3, 6 and 9 days at 41°c and 90-100% relative humidit...

objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

Given the myriad of age-related changes and the many proposed mechanistic theories of ageing, a major problem in gerontology is distinguishing causes from effects. This review aims to identify and evaluate those mechanisms which have gathered experimental support in favour of seeing them as a cause rather than an effect of ageing. Recent results related to energy metabolism and ageing, the free...

ageing is a complex process and a broad spectrum of physical, psychological, and social changes over time. accompanying diseases and disabilities, which can interfere with cancer treatment and recovery, occur in old ages. micrornas (mirnas) are a set of small non-coding rnas, which have considerable roles in post-transcriptional regulation at gene expression level. in this review, we attempted ...

Ageing is a leading risk factor for many debilitating diseases. While age-related diseases have been the subject of over a century of intense investigation, until recently, physiological ageing was considered unavoidable. Pharmacological and genetic studies have since shown that ageing is a malleable process and that its abrogation can prevent its associated diseases. This review summarises a s...

Ageing describes the progressive functional decline of an organism over time, leading to an increase in susceptibility to age-related diseases and eventually to death, and it is a phenomenon observed across a wide range of organisms. Despite a vast repertoire of ageing studies performed over the past century, the exact causes of ageing remain unknown. For over 50 years it has been speculated th...

Human ageing is a global problem that will have a large socio-economic impact. A better understanding of ageing can direct public policies that minimize its negative effects in the future. Over many years, several longitudinal studies of human ageing have been conducted aiming to comprehend the phenomenon, and various factors influencing human ageing are under analysis. In this review, we categ...

In this article, we develop a tentative philosophy to orchestrate and support possibilities for artful ageing. This effort argues that older adults need broader range of opportunities explore the manifold ephemeral, non-rational, in-between elements an ageing life. The is rooted in notion space (literally metaphorically) process their existence engaging such processes can entail emancipatory ef...

The overall aim of this thesis was to investigate genetic and ageing effects on beef quality. To study the genetic effects, association analyses were carried out between single nucleotide polymorphisms (SNPs) at DGAT1, LEP, SCD1, CAPN1 and CAST genes with colour, marbling, water holding capacity (WHC) and tenderness in meat from young bulls of the beef cattle population in Sweden. In total 243 ...
