ACTIV-3/TICO Study Group* Background: Ensovibep (MP0420) is a designed ankyrin repeat protein, a novel class of engineered proteins, under investigation as a treatment of SARS-CoV-2 infection.Objective: To investigate if ensovibep, in addition to remdesivir and other standard care, improves clinical outcomes among patients hospitalized with COVID-19 compared with standard care alone.
An experiment was initiated in April 1972 at the Isabela Substation to evaluate the effect of season of planting and age at harvest on yield and tuber quality of four tanier cultivars. Bimonthly plantings were made from April 1972 to February 1973. Cultivar Kelly was harvested at 8 and 10 months of age, whereas Blanca del País, Morada, and Rascana were harvested at 10 and 12 months. The best planting dates appeared to be from April through August. A sharp reduction in marketable yield was evident for all cultivars planted after this period. For all planting dates the best yields were obtained when both Rascana and Morada were harvested at 12 months of age. Yields of Blanca del País, the standard tanier for the Isabela area, were inferior to those of the other cultivars with the excepton of Kelly. In general all cultivars were favored by the 2-month delay in harvest. However, Rascana was most favored by this delay, which significantly increased the number of marketable tubers. Planting dates and age at harvest had no effect on tuber internal quality. Although the delay in harvest somewhat softened the texture, cooked tubers were rated "acceptable" by a tasting panel.
The effect of various soil acidity factors on yield and foliar composition of sweet potato (Ipomoea batatas (L). Lam) were determined in three Ultisols and one Oxisol. Sweet potatoes responded moderately in yield to variations in soil acidity factors of three Ultisols, but did not on the Oxisol. On the Ultisols, soil acidity factors had very little effect on leaf composition. Yield increased with increasing soil pH, decreasing exchangeable Al content and decreasing exchangeable Al/base ratio. When all the soils, except Coto, were grouped together, the ratio of exchangeable Al to exchangeable bases explained 83% of the variation, the percent Al saturation 79%, and pH only 66%. Highest yields were obtained when pH was above 5, percent AI less than 20% and the Al exchangeable bases ratio less than .2. The lack of response in the Oxisol seems to be related to a reduced Al activity resulting from a high Mn concentration in the soil solution. Apparently sweet potato is very tolerant to high Mn concentrations in the soil solution.
An experiment was conducted to determine if the P fertilizer response of corn planted in sunken bottomless drums was comparable to that in the field. Subsoil and surface of an Ultisol (Orthoxic Palehumults) soil low in available P were placed in sunken drums and planted to corn with and without added P. P response experiments also were carried out with the same soil in the field and in pots in the greenhouse. There was a significant yield and P uptake response to added P in the drum and pot experiments but not in the field, indicating that neither sunken drum experiments nor greenhouse pot tests substitute for field tests in determining response to P by corn.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
