A rapid and simple immuno-chromatographic assay was developed to detect aflatoxin B1 (AFB1). The assay was based on a modified competitive binding format using colloidal gold and polyclonal antibody (Pab) conjugates. The anti-AFB1 Pab was immobilized to a defined detection zone on a porous nitrocellulose membrane and colloidal gold particles were conjugated to AFB1-BSA which served as a detecti...
A small amount of southern bean mosaic virus was contained in a narrow zone after density-gradient centrifugation, but in a much wider zone after centrifugation with a large amount of a second virus. Zone-spreading of a major component by non-ideal sedimentation in density-gradient centrifugation can cause zone spreading of a minor component that the major component overlaps.
DOUTfinder is a web-based tool facilitating protein domain detection among related protein sequences in the twilight zone of sequence similarity. The sequence set required for this analysis can be provided by the user or will be collected using PSI-BLAST if a single sequence is given as an input. The obtained sequence family is analyzed for known Pfam and SMART domains, and the thereby identifi...
The mechanisms of autowaves propagation through local non-homogeneities in active media relevant to diverse class of physiological systems were studied by means of a computer simulation. The model proposed by Zel'dovich and Frank-Kamenetsky and that of FitzHugh-Nagumo were used for studying autowave tunneling, which in a broad sense implies underbarrier passing. It was shown that for every fixe...
Serum succinate may offer an alternate analyte to lactate for the evaluation of hypoxia. To evaluate the potential uses of succinate, a relatively rapid capillary zone electrophoresis assay was developed for use in the clinical laboratory setting. Employing a simple indirect ultraviolet detection method with commercially available instrumentation, the limit of detection for serum succinate was ...
The cohesive energy of condensed matter in strong magnetic fields is a fundamental quantity characterizing magnetized neutron star surfaces. The cohesive energy refers to the energy required to pull an atom out of the bulk condensed matter at zero pressure. Theoretical models of pulsar and magnetar magnetospheres depend on the cohesive properties of the surface matter in strong magnetic fields....
In this paper we present a multi-pedestrian detection and tracking framework targeting a specific application: detecting vulnerable road users in a truck’s blind spot zone. Research indicates that existing non-vision based safety solutions are not able to handle this problem completely. Therefore we aim to develop an active safety system which warns the truck driver if pedestrians are present i...
Smartphone-based point-of-care testing of salivary α-amylase for personal psychological measurement.
Here we report a smartphone-based potentiometric biosensor for point-of-care testing of salivary α-amylase (sAA), which is one of the most sensitive indices of autonomic nervous system activity, and therefore a promising non-invasive biomarker for mental health. The biosensing system includes a smartphone having a sAA-detection App, a potentiometric reader and a sensing chip with preloaded reag...
چکیده موضوع: مطالعه زیست چینه نگاری سازند گورپی بر اساس فرامینیفرهای پلانکتون در شمال شرق گچساران (تاقدیس آنه) می باشد. سازند گورپی با مختصات جغرافیایی 30 درجه، 30 دقیقه عرض شمالی و 50 درجه، 30 دقیقه طول شرقی در ناحیه مورد مطالعه شامل 112 متر آهکهای خاکستری نازک لایه و آهک با بین لایه های نازک از شیل می باشد. سازند گورپی به طور ناپیوسته بر روی آهکهای ضخیم لایه سازند سروک قرار دارد و در بالابه...
