The effect of seeding depth on emergence of red rice (Oryza sativa) ecotypes from Arkansas (AR), Louisiana (LA), and Mississippi (MS) was determined under dry-seeded rice production in clay and silt loam soils in Arkansas. By 21 d after planting (DAP), all red rice ecotypes had emerged from planting depths of 1.3, 2.5, 5.0, and 7.5 cm in both clay and silt loam soils. In silt loam soil, seedlin...

Monophasic ascending ramp (AR) and descending ramp (DR) waveforms are known to have significantly different defibrillation thresholds. We hypothesized that this difference arises due to differences in mechanisms of arrhythmia induction for the two waveforms. Rabbit hearts (n = 10) were Langendorff perfused, and AR and DR waveforms (7, 20, and 40 ms) were randomly delivered from two line electro...

Results: Mean age of the patients was 56.9±11.2 years. Mean AR CAG repeat length and serum testosterone levels were 26.7±8.9 and 5.6±2.3 ng/mL, respectively. A Total of 64 men (26.6%) were diagnosed with MS and 22 men we...

INTRODUCTION Beta-adrenoceptors (β-AR) play an important role in the neurohumoral regulation of cardiac function. Three β-AR subtypes (β(1), β(2), β(3)) have been described so far. Total deficiency of these adrenoceptors (TKO) results in cardiac hypotrophy and negative inotropy. TKO represents a unique mouse model mimicking total unselective medical β-blocker therapy in men. Electrophysiologica...

Testosterone (T) and related androgens are performance enhancing drugs (PEDs) abused by some athletes to gain competitive advantage. To monitor unauthorized androgen abuse, doping control programs use mass spectrometry (MS) to detect androgens, synthetic anabolic-androgenic steroids (AASs) and their metabolites in an athlete's urine. AASs of unknown composition will not be detected by these pro...

Therapeutic drug monitoring is an esential tool for a positive management therapy. The prefered laboratory strategy is immunoassay. Due to the cross-reactivity to other components, alternative approaches, such as LC-MS, are continously under investigation. The paper described briefly the main aspects regarding LC-MS apparatus and technique and recent applications on therapeutic drug monitoring,...

Two experiments evaluated the effects of conventional and natural feedlot management systems (MS) on ractopamine-HCl (RAC) response in yearling steers. Feedlot performance, carcass characteristics, skeletal muscle gene expression, and circulating IGF-I concentrations were measured. The conventional system included a combined trenbolone acetate and estradiol implant, Revalor-S (IMP), as well as ...

normal 0 false false false en-us x-none ar-sa radiation therapies are commonly used for malignant or metastatic brain tumors for curative and palliative use. the radiation-induced neurotoxicity includes both parenchymal and vascular damage. here we report the case of a 43-year-old woman who developed multiple sclerosis (ms) 9 months after she underwent the last session of radiotherapy for the d...
