Pharmacological activation of a novel p53-dependent S-phase checkpoint involving CHK-1.
We have recently shown that induction of the p53 tumour suppressor protein by the small-molecule RITA (reactivation of p53 and induction of tumour cell apoptosis; 2,5-bis(5-hydroxymethyl-2-thienyl)furan) inhibits...

Maya Pottery Production at Nakum, Guatemala, during the Protoclassic Period (100/50 BC – AD 300/350)
This study investigates the Protoclassic ceramic production at Nakum, Guatemala, using it as a proxy to explore the nature of the transition from the Preclassic to Classic period (100/50 BC – AD 300/350) in Central Maya...

The Role of Language in Structuring Social Networks Following Market Integration in a Yucatec Maya Population.
Language is the human universal mode of communication, and is dynamic and constantly in flux accommodating user needs as individuals interface with a changing world. However, we know surprisingly little about how language...
Changing language input following market integration in a Yucatec Mayan community
Like many indigenous populations worldwide, Yucatec Maya communities are rapidly undergoing change as they become more connected with urban centers and access to formal education, wage labour, and market goods became more...

Elucidation of the mechanisms of action of Bacteriophage K / nano-emulsion formulations against <i>S. aureus</i> via measurement of particle size and zeta potential
In earlier work we have demonstrated the effect that nano-emulsions have on bacterial growth, and most importantly the enhanced bacteriophage infectivity against S. aureus in planktonic culture when phage are carried in...
Examining the Evolution of Interaction between Researchers and Indigenous Populations: An Investigation of Archaeologists and the Maya

Interactions with Indigenous populations around the world have been, and continue to be, riddled with the remnants of colonialist and imperialist ideals. This can be especially true when considering archaeologists and the modern...

Inactivation of the von Hippel-Lindau tumour suppressor gene induces Neuromedin U expression in renal cancer cells.
BACKGROUND: 209 000 new cases of renal carcinoma are diagnosed each year worldwide and new therapeutic targets are urgently required. The great majority of clear cell renal cancer involves inactivation of VHL, which acts as a...
The Serine Protease Homolog, Scarface, Is Sensitive to Nutrient Availability and Modulates the Development of the <i>Drosophila</i> Blood-Brain Barrier.
The adaptable transcriptional response to changes in food availability not only ensures animal survival but also lets embryonic development progress. Interestingly, the CNS is preferentially protected from periods of...
Combined use of bacteriophage K and a novel bacteriophage to reduce <i>Staphylococcus aureus</i> biofilm

Biofilms are major causes of impairment of wound healing and patient morbidity. One of the most common and aggressive wound pathogens is Staphylococcus aureus, displaying a a large repertoire of virulence factors and...
Mixing closures for conservation laws in stratified flows
A closure for shocks involving the mixing of the fluids in two-layer stratified flows is proposed. The closure maximizes the rate of mixing, treating the dynamical hydraulic equations and entropy conditions as constraints. This...
Placental adaptations supporting fetal growth during normal and adverse gestational environments.
NEW FINDINGS: What is the topic of this review? How the placenta, which transports nutrients and oxygen to the fetus, may alter its support of fetal growth developmentally and with adverse gestational conditions. What advances...
The diurnal cycle and the meridional extent of the tropics
An explanation is proposed for the meridional extent of the Hadley cells: the diurnal waves forced by solar heating trapped between −30°and 30°. These baroclinic waves, we propose, give rise to the daily nature of tropical...
Consent in Conversation: Education of Sexual Violence in Maya Angelou's I Know Why the Caged Bird Sings
Emily Benning
Jan 01, 0001
Maya Angelou's memoir, I Know Why the Caged Bird Sings, is just one of many titles challenged and banned in public schools for "sexually explicit" content. On page 71 of her 281 page autobiography, Angelou discloses that she was...

Conservation law modelling of entrainment in layered hydrostatic flows
A methodology is developed for modelling entrainment in two-layer shallow water flows using non-standard conserved quantities, replacing layerwise mass conservation by global energy conservation. Thus, the energy that the...

Jul 10, 2020
Abstract: Insertions and deletions (InDels) are frequently observed in natural protein evolution, yet their potential remains untapped in laboratory evolution. Here we introduce a transposon-based mutagenesis approach (TRIAD) to...

Dec 23, 2014
The use of hydrogels as safe, biocompatible materials for wound healing has been widely utilized in recent years. Here, we investigated the use of a composite hydrogel to impart a “trigger” mechanism into an antimicrobial...
