The gvfr is a minimum or simple model based only on the assumption that a velocity field may be used effectively to illustrate experimental results concerning the temporal evolution of the size and shape of the organism that reveals the centers of growth and growth gradients first described by huxley (1924, “constant differential growth.
Reproductive senescence and menopause in killer whales killer whales represent a model organism for examining potential benefits of long lived mothers and grandmothers. Like humans, killer whales are extremely long lived, experience differential sex-specific mortality [ 22 ], and females have long post-reproductive lifespans.
Few convincing studies of senescence in perennial herbaceous plants exist. While ramets are known to senesce, whether senescence of bunchgrasses actually occurs is not clear. In this study, we grew a set of plants of elymus excelsus, a bunchgrass, to examine plan.
What is senescence? cellular senescence refers to a state of stable cell cycle arrest in which proliferating cells become resistant to growth-promoting stimuli,.
Cellular senescence is a process that results from a variety of stresses and leads to a state of irreversible growth arrest.
Riabowol and colleagues show that the life spans of widely varying canine breeds correlate well with their average telomere length, supporting suggestions from some studies of human telomeres that telomere length contributes to determining life span. Dog telomeres erode ∼10-fold faster than human telomeres, which is proportional to the average life spans of these species.
In purebred dogs, such evolution is confounded by selection during breeding, which combines genes from different, more ancient, breeds without allowing subsequent counterselection that would offset ill effects in later life. In this paper, we have presented a first report on the distribution of phenotypes that were encountered.
Masle [23] reported that in winter wheat senescence begins with the most recently emerged tiller and proceeds towards the preceding groups of tillers in the order of their age and slackening of growth spreads progressively from the youngest to the oldest tiller in sequence to their initiation time and eventually to the main stem.

Cinerea on floral tissues is to treat them with low concentrations of hypo-chlorite. Floral senescence is an active process with many of the hallmarks of programmed cell death. Molecular analysis has revealed a large number of candidate genes with possible roles in senescence and remobilization.
Quote: cellular senescence is a molecular hallmark of ageing that is associated with multiple pathologies, and dna damage marker γh2ax, together with cell cycle inhibitor p21, have been used as senescence markers in multiple species including dogs.
Organisms cannot allocate unlimited resources to growth, maintenance (repair), and reproduction throughout life. Although large size can increase short-term survival and fecundity, growing large rapidly and maintaining a large body size might come at the cost of reduced survival later in life.
The issue of body size and lifespan is a fascinating topic in biology. It’s strange that across species, at least in mammals, large.
Plant hormonal signals participate in various plant growth and developmental stages, including embryogenesis, seed germination, vegetative growth, fruit ripening and leaf senescence. Therefore, the exploration of plant hormones and their regulatory roles in growth and development of lrs have been extensively reported.

However, it should be noted that the cxcr2/senescence study was performed in vitro in the absence of immune cells, and secretion of cxcr2 ligands was an important component of the response in vivo, this would be expected to initiate local inflammation, which could mask any senescence-related tumor suppressor effects mediated by cxcr2.

Temperature and breeding density significantly affected the growth and development of purebred and crossbred tadpoles. Compared with purebred tadpoles, the hybrids showed heterosis under similar experimental conditions. The genetic diversity of the crossbred tadpoles was higher than that of the parents.
This review questions the old paradigm that describes the heart as a post–mitotic organ and introduces the notion of the heart as a self–renewing organ regulated by a compartment of multipotent.
This paper proposes a single species system under seasonal succession and impulsive perturbations. The system is composed of two processes: one governed by the gompertz equation, and the other modelled by the logistic equation. Some very general, weak criteria on the permanence, existence, uniqueness and global stability of the positive.
