Heat stress-induced or stress-accelerated leaf senescence is related to the accumulation of ethylene and loss chlorophyll in cool-season grass species. The objective this study was determine whether foliar-spraying inhibitor, aminoethoxyvinylglycine (AVG), may suppress heat-induced through effects on synthesis degrading enzymes creeping bentgrass ( Agrostis stolonifera ). Plants were maintained...
Abstract Pre-synchronization strategies with prolonged exposure to exogenous progesterone have the potential alter estrus expression and improve fertility in beef cows. The objective of this study was evaluate response pregnancy rate suckled cows enrolled two fixed-time artificial insemination (TAI) protocols. A total 1,216 (angus-crossed) at 10 locations across VA were study. Within location, ...
The aims of this study were, first, to evaluate the effects of climatic variables on daily feed intake of lactating sows and, second, to establish whether the response of sows to variation in temperature on feed intake during lactation was heritable. A total of 82,614 records for daily feed intake during lactation were available for 848 sows with 3,369 litters farrowing from January 2000 to Dec...
BACKGROUND Left atrioesophageal fistula is a rare but devastating complication that may occur after catheter ablation of atrial fibrillation. We used capsule endoscopy to assess esophageal injury after catheter ablation for atrial fibrillation in a population randomized to undergo general anesthesia or conscious sedation. METHODS AND RESULTS Fifty patients undergoing atrial fibrillation ablat...
In order to investigate the relative impacts of increases in day and night temperature on tree carbon relations, we measured night-time respiration and daytime photosynthesis of leaves in canopies of 4-m-tall cottonwood ( Populus deltoides Bartr. ex Marsh) trees experiencing three daytime temperatures (25, 28 or 31 ∞ C) and either (i) a constant nocturnal temperature of 20 ∞ C or (ii) increasin...
The maintenance of the quality and storage life of perishable fruits and vegetables is a major challenge for the food industry. In this study, the effects of different temperatures, packaging materials and storage time on the stability of capsaicinoids and antioxidants, such as total carotenoids, ascorbic acid and total phenolic compounds, were studied in three commercially cultivated hot peppe...
OBJECTIVE To evaluate the pharmacokinetics of TX-004HR vaginal estradiol softgel capsules when used for treating moderate-to-severe dyspareunia in postmenopausal women with vulvar and vaginal atrophy. METHODS A substudy of the REJOICE trial (multicenter, double-blind, placebo-controlled, phase 3) evaluated the pharmacokinetics of 4, 10, and 25-μg TX-004HR doses once/d for 2 weeks, followed by...
As the risk of open-field cultivation increases with climate change, some analysts say that day when ordinary vegetables will be produced at home is not far away. Moreover, due to recent coronavirus outbreak, outdoor activities are becoming difficult, leisure can done have become more necessary, and demand for gardening has increased. This study was conducted improve technology hydroponics home...
Stem tissues of red-osier dogwood (Cornus stolonifera Michx.) acclimated from -3 C to -40 or -50 C in 8 to 10 weeks under a short photoperiod (9 hours) and controlled temperature conditions. During the summer months plants did not acclimate as well as at other times. The sequence of day/night temperature regimes which induced maximum acclimation was 20/15 C for 5 to 6 weeks; 15/5 C for 2 to 3 w...
The survival of selected viruses in Lactobacillus- and yeast-fermented edible waste material was studied to determine the feasibility of using this material as a livestock feed ingredient. Five viruses, including Newcastle disease virus, infectious canine hepatitis virus, a porcine picornavirus, frog virus 3, and bovine virus diarrhea, were inoculated into a mixture of ground food waste (collec...
