Introduction: Radiochemical purity (RCP) is a routine quality control test carried out at nuclear medicine to determine the concentration of various chemical species present in the radiopharmaceuticals (RPs). The present work describes three years of experience in a single institute for the measurement of these impurities in the RPs preparations. Methods: </strong...
We screened for natural mutations in Crl:CF1 closed colony mice using an ordinary backcrossing system. Five of 30 CF1 males carried novel genes that caused white spots on colored coats. Their backcross progenies showed a white spot phenotype. The white spot gene was mapped to approximately 39 cM on chromosome 5, where the Kit gene is known to reside. Allelism testing between this spot gene and ...
イムノクロマト法を用いたテトロドトキシン(TTX)検査キットの有効性について検討した。マトリックス非存在下では,0.0125-0.2マウス単位 (MU)/mLの濃度範囲で,テストプレートに形成されるCラインとTラインの強度比(T/C)とTTX濃度の対数の間に強い負の相関が認められ,終濃度約0.06 MU/mLを検出限界として目視によりTTXの有無を判定することができた。一方,マトリックスが存在する場合,その影響を前処理で低減しても偽陽性が出やすかったが,偽陰性は全く認められなかった。
Background: Malaria is still account for 200 million cases annually. Microscopy is the gold standard technique for malaria parasites detection. PCR-based techniques can detect malaria infections with high sensitivity. The study aimed to evaluate the sensitivity of microscopy technique in the detection of P. falciparum and P. vivax, using monoplex real-time PCR, Gezira State, Central Sudan. Met...
cystic hydatid disease (hydatidosis) is the most serious tape-worm infection prevalent in the cattle and sheep raising area of the world. hydatidosis in man (as an accidental host) caused by infection with the ova containing larval stage of echinococcus spp. in the last decade different techniques have been employed for the serological diagnosis of hydatid disease, such as iha, ifa, elisa, ccle...
A new algorithm is proposed which accelerates the mini-batch k-means algorithm of Sculley (2010) by using the distance bounding approach of Elkan (2003). We argue that, when incorporating distance bounds into a mini-batch algorithm, already used data should preferentially be reused. To this end we propose using nested mini-batches, whereby data in a mini-batch at iteration t is automatically re...
given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. this study was conducted during 2012-2013 at the research center of agricultural university of tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. a...
In this review, we examine the greenest nanoparticles of zero-valent metals, metal oxides and metal salts, with emphasis on recent developments routes. Products from nature or those derived from natural products, such as extracts of several plants or parts of plants, tea, coffee, banana, simple amino acids, as well as wine, table sugar and glucose, have been used as reductants and as capping ag...
