Establishment of the nitrogen-fixing nodulation symbiosis between legumes and rhizobia requires plant-wide reprogramming to allow infection and development of nodules. Nodulation is regulated principally via a mechanism called autoregulation of nodulation (AON). AON is dependent on shoot and root factors and is maintained by the nodulation autoregulation receptor kinase (NARK) in soybean. We de...
This paper reports the development, characterization, and application of a separation-free, homogeneous, and simple to perform fluorescence polarization bioassay for paclitaxel. The bioassay is based on the binding interaction of paclitaxel to tubulin, the receptor protein on which this drug acts. The bioassay was carried out in a competitive format where the paclitaxel and a synthetic fluoresc...
PubChem's BioAssay database (https://pubchem.ncbi.nlm.nih.gov) has served as a public repository for small-molecule and RNAi screening data since 2004 providing open access of its data content to the community. PubChem accepts data submission from worldwide researchers at academia, industry and government agencies. PubChem also collaborates with other chemical biology database stakeholders with...
A laboratory bioassay was developed for testing tarnished plant bug populations for resistance development to the neonicotinoid insecticides imidacloprid and thiamethoxam. The bioassay allows for the determination of LC50 values by feeding known doses of the insecticides to adult tarnished plant bugs in a honey-water solution. Field populations of plant bugs from several locations in the mid-So...
-Peripheral-blood basophils were counted, in thick smears, in samples from patients with primary bronchial carcinoma, from patients in the same wards and from normal individuals. The median counts for patients with other chest conditions (15-5/4d) and bronchial-carcinoma patients free of tumour months to years after resection (16/1l) did not differ from those for normal individuals (19/1,u), bu...
BACKGROUND Experimental investigation of stroke, in particular the evaluation of therapeutic maneuvers, is difficult because even well-controlled experiments show considerable variability. Optimal use of resources requires efficient statistical analysis. SUMMARY OF REVIEW A body of experience in pharmacology that is directly applicable to stroke studies is reviewed. The general approach, thou...
The primary focus of this study is to assess the toxicity chemical corexit 9527 28 day old fresh water tilapia guineensis fingerlings. fingerlings was studied in static renewal bioassay glass tank, using tap water. collected from Ikpoba HillRiver, Edo State used access lethal concentrations dispersant 9527. Differential sensitivity test organisms observed.This achieved by predictive application...
an agar well diffusion bioassay method for determination of clarithromycin in human plasma, using micrococcus luteus atcc 9341 as the assay organism, was compared with a selective high-performance liquid chromatographic (hplc) method with uv detection. spiked plasma was used to prepare standard and control samples for both methods. the results of the bioassay analyses with spiked plasma samples...
ناکاملی هندسی در ستون ها از مواردی می باشد که وجود آن در اعضای سازه ای را نمی توان نادیده گرفت، در هر عضو سازه ای ناکاملی هندسی هر چند بسیار کوچک وجود خواهد داشت از این رو بررسی تاثیرات این ناکاملی ها و همچنین پیدا کردن مقدار مجاز برای آنها در طراحی سازه های فولادی دارای اهمیت خاصی می باشد. هدف این پژوهش بررسی رفتار قاب های فولادی با ناکاملی در مختصات گرهی به میزان 3، 6 و 9 میلی متر بوده که برا...
