Aging and mitochondrial dysfunction in the filamentous fungus Podospora anserina
In the filamentous fungus Podospora anserina, mitochondria play a paramount role in life span control and aging. During aging, these organelles...
-
The human Werner Syndrome as a model system for aging
The aging process is one of the most challenging biological pathways to understand. Applications of model systems for aging have contributed...
-
Aging and the programmed death phenomena
Biochemical mechanisms of the programmed death phenomena are considered at levels of unicellular organisms, mitochondria, cells, groups of cells, and...
-
Energy metabolism, anti-oxidant defense and aging in Caenorhabditis elegans
Food restriction and impaired gene function by mutation or RNAi treatment can extend the lifespan of Caenorhabditis elegans considerably. In contrast...
-
Do green plants age, and if so, how?
Time-dependent ageing-like processes in green plants are discussed and compared to gerontological changes in animals and other organisms. The...
-
Conditional senescence in prokaryotes
Bacteria are immortal in the sense that their capacity for reproduction appears limitless as long as the environment supports growth. However, this...
-
Yeast as a model for ageing and apoptosis research
Apoptosis is a form of programmed cell death with a crucial role in health and disease in metazoans. Recent findings demonstrate the existence of an...
-
Mammalian and bird aging, oxygen radicals, and restricted feeding
In this chapter, the relationship of aging with oxidative stress is reviewed. Endogenous tissue antioxidants do not determine aging because they...
-
Role of subcytotoxic stress in tissue ageing
Most commonly stress-induced premature senescence (SIPS) is defined as the long-term effects of subcytotoxic stress on proliferative cell types,...
-
Mitochondria, metabolism, and aging in yeast
Quantitative and qualitative changes in metabolism take place when the lifespan is extended in yeast either by genetic or nutritional manipulation....

Friends and foes: competition experiments reveal growth facilitation and interference between cyanobacteria and diatom strains in microbial mats
Community dynamics within microbial mat assemblages are complex, likely involving intricate metabolic linkages. Interactions between microbes shape...

Changes in benthic communities in Blagopoluchiya Bay (Novaya Zemlya, Kara Sea): the influence of the snow crab
Until recently, the Kara Sea was a stable ecosystem unaffected by alien species invasions. However, at the beginning of the twenty-first century, the...

Long sediment-laden algal turf likely impairs coral recovery on Florida’s coral reefs
Coral reefs in the Florida Reef Tract have seen protracted loss of coral over the past several decades due to a variety of disturbances from marine...

Efficacy of the dietary Malva parviflora leaves in modulating immune-antioxidant functions, resistance to Candida albicans and Streptococcus agalactiae infection, digestive/absorptive capacity, and growth of Nile tilapia (Oreochromis niloticus)
Recently, the intervention of herbal plants in the fish diet has drawn a lot of interest due to their unique nutritional value and pharmacological...

Rushing and spawning behavior of the Kidako moray Gymnothorax kidako
This study investigated the reproductive behavior of the Kidako moray Gymnothorax kidako in Tateyama, Chiba, Japan and Enoshima Aquarium. Field...

Effects of warm oceanographic anomalies on the foraging variability of northern elephant seals
Evaluation of stable carbon (δ 13 C) and nitrogen (δ 15 N) isotopes in marine organisms over time addresses how environmental variability (e.g., El...
-
Aberrant telomeric structures and serum markers of telomere dysfunction in healthy aging: a preliminary study
Telomeres undergo a progressive shortening process as individuals age, and it has been proposed that severely shortened and dysfunctional telomeres...
-
Comparable foraging effort and habitat use between two geographically proximate tropical seabird colonies
Effective seabird conservation requires understanding their marine spatial ecology. Tracking can reveal details of their foraging ecology and habitat...

The influence of sex-specific factors on biological transformations and health outcomes in aging processes
The aging process demonstrates notable differences between males and females, which are key factors in disease susceptibility and lifespan. The...
