A New Architecture for DNA-Templated Synthesis in Which Abasic Sites Protect Reactants from Degradation.

The synthesis of artificial sequence-defined polymers that match and extend the functionality of proteins is an important goal in materials science. One way of achieving this is to program a sequence of chemical reactions between precursor building blocks by means of attached oligonucleotide adapters. However, hydrolysis of the reactive building blocks has so far limited the length and yield of product that can be obtained using DNA-templated reactions.

Changes in the metabolic profiles of dairy cows before and after calving that were mainly fed fodder beet ( L.) during the dry period.

: Two commercial pasture-based farms within the North Canterbury district of New Zealand were feeding fodder beet ( L.) as a large proportion of the diet to cows during the dry period. On each farm 25 multiparous cows were blood sampled up to six times from 28 days before, to 21 days after calving (Day 0).

Preliminary investigation of the effect of treating sheep during pregnancy with a vitamin A, D, E formulation on the incidence of vaginal prolapse.

To determine if vitamin D treatment reduced the incidence of vaginal prolapse in pregnant sheep on a North Canterbury sheep breeding property. Pregnant ewes from a single farm were allocated to three treatment groups in May 2018. At this time, the first group (EarlyVitADE; n = 512) received an I/M 1 mL dose of 500,000 IU/mL vitamin D, 60,000 IU/mL vitamin A, and 25 mg/mL vitamin E.
