Lessons learnt in photocatalysis - the influence of solvent polarity and the photostability of the photocatalyst.

Herein, we show that there is significant variation in both the triplet energies and redox properties of photocatalysts as a function of solvent based on a study of eight PCs in four solvents of varying polarity. A range of photocatalytic electron and energy transfer reactions were investigated using a subset of the PCs. For the photoredox reactions, the yields are not correlated with solvent polarity.

Production, Characterisation and Testing of an Ovine Antitoxin against Ricin; Efficacy, Potency and Mechanisms of Action.

Ricin is a type II ribosome-inactivating toxin that catalytically inactivates ribosomes ultimately leading to cell death. The toxicity of ricin along with the prevalence of castor beans (its natural source) has led to its increased notoriety and incidences of nefarious use. Despite these concerns, there are no licensed therapies available for treating ricin intoxication.

The non-human primate striatum undergoes marked prolonged remodeling during postnatal development.

We examined the postnatal ontogeny of the striatum in rhesus monkeys (Macaca mulatta) to identify temporal and spatial patterns of histological and chemical maturation. Our goal was to determine whether this forebrain structure is developmentally static or dynamic in postnatal life. Brains from monkeys at 1 day, 1, 4, 6, 9, and 12 months of age (N = 12) and adult monkeys (N = 4) were analyzed.

Nursing intuition as an assessment tool in predicting severity of injury in trauma patients.

Emergency nurses assess patients using objective and subjective data. When the charge nurse takes report from a paramedic, another form of assessment occurs. By eliciting apt data and using trauma-scoring criteria, a decision to enact a "trauma code" occurs.
