Using eDNA tools to examine the impact of kelp farming on underlying sediments.

Using environmental DNA (eDNA)-based tools, we examined sediments underlying a ~ 1.25 hectare commercial kelp farm in the Gulf of Maine growing sugar kelp (Saccharina latissima) for two farming seasons, post-harvest. Two eDNA methods were used: a newly designed S.

Ventricular Arrhythmias in Patients Undergoing Degenerative Mitral Repair: Prevalence and Impact on Survival.

Objective: Ventricular arrhythmias occur in a subset of patients with mitral valve prolapse. However, their impact on post-operative survival after degenerative mitral repair is unclear.

Methods: We compared long-term survival after degenerative mitral repair in patients presenting with and without arrhythmic mitral valve prolapse (defined by degenerative mitral regurgitation and ventricular arrhythmias) in a national insurance database.

The antimethanogenic efficacy and fate of bromoform and its transformation products in rumen fluid.

Enteric methane emissions from ruminant livestock are a significant source of atmospheric methane. Efforts to address rising atmospheric methane concentrations have led to an expansion of research into mitigating enteric methane production. One of the most effective approaches utilizes bromoform-containing feed supplements, such as the algae Asparagopsis spp.

Feeding incremental amounts of the red seaweed Chondrus crispus: Effects on production performance, methane emissions, nutrient utilization, and ruminal and iodine metabolism in dairy cows.

We investigated the effects of feeding incremental amounts (0%, 3%, and 6% of diet DM) of the red seaweed Chondrus crispus on DMI, milk yield and milk components, enteric CH emissions, nutrient utilization, ruminal fermentation and microbiota relative abundance, and I metabolism in dairy cows. Eighteen organic certified Jersey cows (12 multiparous and 6 primiparous) averaging (mean ± SD) 94 ± 45 DIM, 22 ± 5.2 kg of milk/d, and 485 ± 54 kg of BW in the beginning of the study were used in a replicated Latin square design with three 24-d periods (14 d for diet adaptation and 10 d for data and sample collection).
