Eusociality in African mole-rats: new insights from patterns of genetic relatedness in the Damaraland mole-rat ( Cryptomys damarensis ) [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2002
After the discovery of eusociality in the naked mole-rat, it was proposed that inbreeding and high colony relatedness in this species were the major underlying factors driving cooperative breeding in African molerats. By contrast, field and laboratory studies of the eusocial Damaraland mole-rat (Cryptomys damarensis) have raised the possibility that ...

Spatial and temporal activity patterns of the free-living giant mole-rat (Fukomys mechowii), the largest social bathyergid. [PDF]

PLoS ONE, 2013
Despite the considerable attention devoted to the biology of social species of African mole-rats (Bathyergidae, Rodentia), knowledge is lacking about their behaviour under natural conditions.

Energetics and Water Flux in the Subterranean Rodent Family Bathyergidae

Frontiers in Ecology and Evolution, 2022
The doubly labeled water (DLW) technique and indirect calorimetry enable measurement of an animal’s daily energy expenditure (DEE, kJ/day), resting metabolic rate (RMR, kJ/d), sustained metabolic scope (SusMS), body fat content (BF, %) as well as water ...

Hypofunctional TrkA Accounts for the Absence of Pain Sensitization in the African Naked Mole-Rat [PDF]

Cell Reports, 2016
The naked mole-rat is a subterranean rodent lacking several pain behaviors found in humans, rats, and mice. For example, nerve growth factor (NGF), an important mediator of pain sensitization, fails to produce thermal hyperalgesia in naked mole-rats. The sensitization of capsaicin-sensitive TRPV1 ion channels is necessary for NGF-induced hyperalgesia ...

Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

Journal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is

Absence of histamine-induced itch in the African naked mole-rat and "rescue" by Substance P

Molecular Pain, 2010
Recent research has proposed a pathway in which sensory neurons expressing the capsaicin activated ion channel TRPV1 are required for histamine-induced itch and subsequent scratching behavior.

Melatonin secretion in a strictly subterranean mammal, the Damaraland mole-rat (Cryptomys damarensis) [PDF]

, 2003
Subterranean mammals inhabit an environment that is normally devoid of light and are therefore deprived of photoperiodic information that can be used to time important life-history events.

The best of both worlds : no apparent trade-off between immunity and reproduction in two group-living African mole-rat species [PDF]

, 2023
Electronic supplementary material is available online at https://doi.org/10.6084/m9.figshare.c.6662602.Co-operatively breeding mammals often exhibit a female reproductive skew and suppression of the subordinate non-breeding group members.

Advancing Environmental Sustainability: The Role of Artificial Intelligence in Monitoring, Predicting, and Controlling Sulfur Dioxide Emissions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Air pollution from sulfur dioxide (SO2) emissions poses significant threats to environmental sustainability, public health, and climate change efforts. Despite advances in monitoring and regulatory frameworks, traditional methods often fall short in accuracy, scalability, and efficiency.
