Megaphyll leaf evolution was a critical event in Earth history that had major consequences for the biotic regulation of the global environment. Zimmermann's telome theory has been widely accepted for over seventy years as the leading explanation for this evolutionary innovation. According to the telome theory, megaphylls evolved from the three-dimensional lateral branches of early vascular land...

Agaporomorphusjulianeae sp. n. is described from the Biological Field Station Panguana, in Huànuco province of central Peru. The new species belongs to the Agaporomorphusknischi-group sensu Miller 2005. Together with Agaporomorphusknischi Zimmermann, 1921 and Agaporomorphuscolberti Miller & Wheeler, 2008 this is the third species of the genus with broadly enlarged male antennomeres. The new spe...

AIM To use a colour matching technique to test the hypothesis that the foveal tritanopic zone is increased in size in diabetes mellitus. METHOD A Wright tristimulus colorimeter was adapted for small field colour matching and colour matches were performed on bipartite fields in the range 12' to 60' of arc. The reference stimulus was 490 nm desaturated with 650 nm and the matching stimulus cons...

The purpose of this investigation was to assess the long-term occlusal stability in a group treated early with headgear (HG) compared with a control group. The total study group comprised 68 children (40 males and 28 females) aged 7.6 years (standard deviation 0.3), randomly divided into two groups of equal size. In the first group, HG treatment was initiated immediately, while in the control g...

Decreasing the population and activation of inflammatory T helper cells in multiple sclerosis (MS) patients using vitamin A derivatives (retinoic acids) has been well documented. The present study determined the effect of vitamin A supplementation on psychiatric signs in MS patients. The subjects were 101 relapsing-remitting MS patients enrolled in a placebo-controlled randomized clinical trial...

The present work aims to present the results of the application of a treatment with high hydrostatic pressure (HHP) on Italian fermented and dry-cured pork products. The products used in this study were portioned cured ham, portioned bacon and salami, vacuumpackaged and produced by a single processing company. Two studies were conducted on a single batch of the three products by means of an art...

This paper uses a non-parametric test, based on consistently estimated discrimination accuracy defined as concordance probability between quantitative predictor and outcome, to compare paired biomarkers in predicting a health outcome, possibly subject to random censoring. Comparing with the Wilcoxon test for paired predictors based on Harrell's C-index, we found that the proposed test is better...

BACKGROUND The Breast Cancer Screening Beliefs Questionnaire (BCSBQ) has been designed as a culturally appropriate instrument for assessing women's beliefs, knowledge and attitudes to breast cancer and breast cancer screening practices. While it has proved to be a reliable instrument when applied to women of Chinese, Arabic and Korean origin living in Australia, its psychometric properties amon...

Introduction Observing the obliquity of stapes by closely scrutinizing the HRCT temporal bone in otosclerosis revealed a reliable and consistent finding. This finding can add to the existing radiological criteria in diagnosis of otosclerosis. Objective The objective of this study is to establish the obliquity of stapes in otosclerosis by radiological measurements using HRCT temporal bone by com...

Dietary patterns are a useful summary measure of diet. Few studies have examined the nutrient profiles underpinning the dietary patterns of young children. The study aim is to determine whether dietary patterns at 6 and 15 months of age are associated with nutrient intakes at 8 and 18 months, respectively. Participants were children from the Avon Longitudinal Study of Parents and Children who h...
