A Situation Analysis of Ley Pasture Utilisation in the Western Downs and Maranoa Regions of S Queensland, Australia

Previous studies have shown that the uptake of ley pasture systems in S Queensland\u27s grain growing region has been slow when compared with mixed farming systems in S Australia. This is despite their demonstrated benefits to subsequent crops, livestock production and the environment. A survey was conducted that aimed to determine the level of utilisation of ley pastures in the Western Downs and Maranoa regions of S Queensland, and the possible constraints to their adoption, and benefits arising from their use. The survey also aimed to determine the commonly used pasture species, the reasons for their use and their contribution to the livestock component of mixed farms

Rhizobial and Nutritional Responses of Desmanthus Clay Soils of Queensland

The objective of these studies was to determine the reasons for chlorosis of desmanthus observed at some sites in southeast Queensland. Inoculation with Rhizobium increased growth of desmanthus in 2 of 4 soils in the field and 4 of 8 soils in pots. Greatest responses occurred in soils with few or no effective native Rhizobium. Most soils however, contained native strains that were effective. Omission of sulphur significantly reduced dry weight of desmanthus grown in pots in 5 of 7 soils by 30-51% relative to plants supplied with all nutrients. Omission of P and Mo resulted in similar yield reductions in one soil each. Both S and Mo deficiency significantly reduced nitrogen concentrations in leaf tissue. Chlorosis therefore appears to be due to low or absent native Rhizobium and/or deficiency of S or Mo. More work needs to be done in the field to determine the extent of nutrient deficiencies and to improve methods of inoculation

A new simple diagnostic assay for the identification of the major CYP2D6 genotypes by DNA sequencing analysis

AIM: To establish a method suitable for diagnostic genotyping of CYP2D6 alleles by DNA sequencing. METHODS: Initial PCR reactions were performed to specifically amplify exons 3, 4, 5 and 6 of the CYP2D6 gene using primers previously published. New primers were used to identify *2, *3, *4, *6, *7, *8, *9 and *41 in 2 sequencing reactions. Additional primers were designed for reverse sequencing in samples with 1 or 3 b.p. deletions. Previously published assays were used to detect *5, *10 and *16 alleles to complete genotype assignment. RESULTS: We reliably detected the nonfunctional alleles, *3, *4, *6, *7 and *8, which are associated with the poor metabolizer phenotype, and 2 important alleles associated with decreased enzyme activity, *9 and *41. Observed allele frequencies were comparable to those found previously in Caucasian populations. CONCLUSION: CYP2D6 genotype has been shown in previous clinical studies to be a good predictor of CYP2D6 phenotype and, therefore, related to therapeutic response and the risk of drug toxicity. This genotyping method is simple and reliable, and, therefore, can be routinely performed on an isolated patient sample, providing a relatively quick turnaround time needed for clinical practice. In addition, the simultaneous drawing of blood with the commencement of drug therapy will allow dosage adjustment on the basis of the CYP2D6 genotype to reduce the risk of adverse drug reactions.H.M.

Using Small-Sided Games in Field Hockey: Can They Be Used to Reach Match Intensity?

Duthie, GM, Thomas, EJ, Bahnisch, J, Thornton, HR, and Ball, K. Using small-sided games in field hockey: Can they be used to reach match intensity? J Strength Cond Res XX(X): 000–000, 2019—Small-sided games (SSGs) are commonly used in field hockey to replicate or overload physical and tactical competition demands; however, little evidence is available regarding if specific SSG formats achieve this. This research investigated how speed and acceleration differed between 5-minute SSG formats (2v2, 3v3, and 4v4) and also compared with competition. Elite male field hockey athletes (n = 10) participated in the SSGs with standard rules, on pitches of 30 × 20, 35 × 25, and 40 × 30 m, respectively (∼150 m2 per athlete excluding goal keepers). Global Positioning System devices measured speed (m·min−1) and acceleration (m·s−2). Differences between mean speed and acceleration during SSGs and 5-minute maximal mean values from competition (calculated using moving averages) were quantified using linear mixed models and described using standardized effect sizes (ES) and 90% confidence intervals. Between SSG formats, there were nonsubstantial differences for mean speed and acceleration (ES range −0.4 to 0.8). Compared with competition, mean speed was substantially lower for all SSG formats (ES range −1.4 to −1.8), whereas mean acceleration was higher (ES range 3.9–4.8). The SSG formats examined had a lower mean speed and higher mean acceleration than the maximal mean observed in competition. Therefore, these SSGs are an effective training drill for the development and overload of acceleration. However, manipulating SSG constraints to expose athletes to the maximal mean competition speed is required
