The objective of this study was to evaluate alternative methods of grassland renewal (reseeding) with perennial ryegrass and quantify their effects on subsequent DM yield, tiller density and nitrate leaching. Two experiments were carried out;the first focused on quantifying the influence of Autumn reseeding (August cultivation), and the second, on Spring reseeding (May cultivation) on sward establishment and grass DM production. The study incorporated six treatments namely: direct drill (DD), disc plus power harrow (DPH), power harrow (PH), conventional-plough, till and sow (PLO), and the chemical application of diquat to suppress the existing sward followed by direct drilling (DIQ), represented a rejuvenation method as opposed to full renewal (Spring trial only). All treatments were compared against a control (old permanent pasture). Reseeded swards produced more seasonal (P < 0.05) and total (P < 0.01 Autumn only) DM yield than the control sward. All reseeding methods increased the perennial ryegrass tiller density of the sward compared to the old permanent pasture (P < 0.05 Autumn trial, P < 0.001 Spring trial). All sward renewal methods evaluated were equally as effective as the conventional method of grassland reseeding with the DIQ rejuvenation method intermediate as measured in terms of DM yield and PRG tiller density. The results of the study show no significant difference in the level of nitrate lost in leachate following reseeding regardless of method used or indeed any difference between reseeded swards and old permanent pasture.

Background: Ingrown toenail often results in a painful cycle of infection and inflammation and can affect the ability to go about everyday activities. In the UK and Europe, there are limited ways to prevent the development of ingrowing toenail without specialist intervention. Treatments are often invasive and may require periods of time off work. This prospective, single-site, non-comparative clinical study evaluates the performance, safety and convenience of a treatment kit that can be applied at home at the earliest signs of ingrowing toenail. Methods: Patients (n = 36) with mild ingrowing toenail used the Scholl Ingrowing Toenail Treatment kit for 6 weeks, with assessments by study investigators at Days 0, 21 and 42. The kit comprised a set of toenail clips and a spray, correct use of which was monitored at site visits and through patient diaries. Results: All patients enrolled in the study completed the 42-day treatment period. Severity of ingrowing toenail was significantly reduced in 88.9% (95% CI: 78.62, 99.15) of patients at the end of the study. Twenty-two patients (61.1%) exhibited full resolution of ingrowing toenail at Day 42 and none showed an increase in severity. Reduction in pain and severity of ingrowing toenail from baseline was significant at Days 21 and 42 (p Conclusions: The ingrowing toenail treatment kit was convenient and easy for patients to use at home and resulted in reduced pain and severity of ingrowing toenail at early stages of the condition.
