title: Unique contributions of anxiety, stress and depression to immunity: A cross-cultural investigation

authors: Breeze, Catherine

abstract: While immunity and psychological distress are strongly associated, studies seldom consider how different types of distress relate to immune functioning. The literature tends to emphasis the impact of stress on immunity. The present cross-sectional study estimated the unique contributions of depression, anxiety, and stress on immune function in culturally diverse samples of adults from Italy, New Zealand and India. Participants were Italian (n = 1061), New Zealand (n =1037), and Indian (n =384) volunteers. Stepwise multiple linear regression and dominance analysis were used to analyse differences in immunity uniquely explained by anxiety, depression, and stress. While samples from the three countries differed significantly, anxiety consistently explained the greatest proportion of differences in immunity. After accounting for the effect of anxiety, stress and depression explained only negligible variation in immune functioning. This association of anxiety with immune functioning was consistent across three different countries and this unique impact was further confirmed by the results of dominance analysis. These findings suggest a clear link between anxiety and immunity, which advances the prevailing stress-disease model and foster further experimental and longitudinal research into the impact of anxiety on immunity.

title: Citrate synthases from the Archaea: Development of a bio-specific, affinity chromatography purification procedure

authors: James, Keith D.

subjects: archaea

abstract: Citrate synthases from both thermophilic and halophilic Archaea have been purified to homogeneity using affinity chromatography on Matrex Gel Red A and elution with a combination of substrate (oxaloacetate) and product (coenzyme A). In a number of cases, purification from cell-extract to protein suitable for N-terminal sequencing can be achieved by this single-step procedure. The method is particularly useful in the rapid purification of a thermophilic archaeal citrate synthase from a cloned gene expressed in a mesophilic host.

title: Culturally relevant assessment: Kaupapa Māori assessment in early childhood education

authors: Rameka, Lesley Kay

abstract: This chant according to Maori tradition is part of the dedication used at the birth of Maui-tikitiki-a-Taranga, the demigod, ancestor superhero of the Pacific. It was also sometimes used to welcome visitors on to marae, linking the visitors with the spiritual world and powers of the Maori gods, Tūmatauenga, Rongomatane and Tane Mahuta and to Hawaiki, the spiritual Maori homeland. It also provides a model of the universe that dates back thousands of years (Shirres, 1997); a model made up of two intimately connected worlds: the spiritual and the material. These worlds are closely linked with activities in the everyday material world coming under the influence of and interpenetrated by spiritual powers (Reilly, 2004a; Shirres, 1997). Consequently people are connected with the universe, with the world of spiritual powers, the world of the gods.
