The Japanese Society of Hypertension (JSH) updated its hypertension management guidelines in 2009. One of the most significant changes with respect to the 2004 version was the stance towards the use of diuretics: in 2004, their use was cautioned against, but in 2009, it was actively promoted. The purpose of ...

Thermal Bergman cyclization of Pt(ii) dialkynylporphyrins reveals a marked reduction in the cyclization temperature relative to the free base and Zn(ii) derivatives. In contrast, photogenerated (3)ππ* population produces no detectable Bergman photocyclization, suggesting that the photoreactivities of the related free base and Zn(ii) derivatives occurs via the (1)ππ* state.

When exposed to a cold environment, a barehanded person experiences pain, cold sensation, and reduced manual dexterity. Both acute (e.g. exercise) and chronic (e.g. cold acclimatization or habituation) processes might lessen these negative effects. The purpose of this experiment was to determine the effect of cold habituation on physiology, perception, ...

A pyrimidine-naphthalene anchored Schiff base (receptor ) showed Al(3+) selective conformational arrest by inhibition of its C[double bond, length as m-dash]N isomerization (cis-trans) leading to its fluorescent switching in aqueous medium. Nevertheless the H(2)PO(4)(-)/HSO(4)(-) bailed receptor from the Al(3+) arrest leading to its switching 'off'. This conformational arrest and bail ...

It has been argued that people in areas with high pathogen loads will be more likely to avoid outsiders, to be biased in favor of in-groups, and to hold collectivist and conformist values. Cross-national studies have supported these predictions. In this paper we provide new pathogen codes for the 186 ...

We have studied the self-assembly of aqueous dispersions of amphiphilic di- and triblock copolyelectrolytes using static and dynamic light scattering. The hydrophobic blocks contained both ionisable and hydrophobic units rendering the association dynamic and thus ensuring that thermodynamic equilibrium was reached. The incorporation of ionisable units into the hydrophobic blocks ...
