Food allergies have seriously affected the life quality of some people and even endangered their lives. At present, there is still no effective cure for food allergies. Avoiding the intake of allergenic food is still the most effective way to prevent allergic diseases. Therefore, it is necessary to develop rapid, accurate, sensitive, and reliable analysis methods to detect food allergens from different sources. Aptamers are oligonucleotide sequences that can bind to a variety of targets with high specificity and selectivity, and they are often combined with different transduction technologies, thereby constructing various types of aptamer sensors. In recent years, with the development of technology and the application of new materials, the sensitivity, portability, and cost of fluorescence sensing technology have been greatly improved. Therefore, aptamer-based fluorescence sensing technology has been widely developed and applied in the specific recognition of food allergens. In this paper, the classification of major allergens and their characteristics in animal and plant foods were comprehensively reviewed, and the preparation principles and practical applications of aptamer-based fluorescence biosensors are summarized. In addition, we hope that this article can provide some strategies for the rapid and sensitive detection of allergens in food matrices.

<p class="Abstract">During the recent years, maritime surveillance has been receiving a growing interest. Ship detection and identification are parts of maritime surveillance in order to dealing with illegal fishery, maritime traffic, sea border activity, or oil spill detection and monitoring. Nowadays, Synthetic Aperture Radar (SAR) as one of active remote sensing technology provide signals to penetrate cloud, can be advantage to be used in tropical region with the intention to monitor sea objects on the sea surface from the space. The availability of Sentinel-1 as SAR imaging mission, providing continuous all-weather, day-and-night imagery, makes it ideal for precise cueing and location of ship activities at sea. Utilization of CFAR (Constant False Alarm Rate) algorithm provided by SNAP (Sentinel Application Platform) software from ESA show rapid detection of ship in the study areas (Madura Strait and Lamong Gulf). Compared with manual ship extraction method, it gives sufficient results.<o:p></o:p></p>

Rapid Switching

Electron microscopy is frequently used in preliminary diagnosis of plant virus diseases by surveying negatively stained preparations of crude extracts of leaf samples. A major limitation of this method is the time required to survey grids when the concentration of virus particles (VPs) is low. A rapid survey of grids for VPs is reported here; the method employs a low magnification, out-of-focus Search Mode similar to that used for low dose electron microscopy of radiation sensitive specimens. A higher magnification, in-focus Confirm Mode is used to photograph or confirm the detection of VPs. Setting up the Search Mode by obtaining an out-of-focus image of the specimen in diffraction (K. H. Downing and W. Chiu, private communications) and pre-aligning the image in Search Mode with the image in Confirm Mode facilitates rapid switching between Modes.

Detection And Identification

There is a variety of methods available for the rapid detection and identification of viruses by electron microscopy as described in several reviews. The predominant techniques are classified as direct electron microscopy (DEM), immune electron microscopy (IEM), liquid phase immune electron microscopy (LPIEM) and solid phase immune electron microscopy (SPIEM). Each technique has inherent strengths and weaknesses. However, in recent years, the most progress for identifying viruses has been realized by the utilization of SPIEM.

Rotavirus is one of the leading causes of pediatric diarrhea globally. Accurate and rapid diagnosis of Rotavirus diarrhea should reduce unnecessary use of antibiotics and ultimately reduce drug resistance. Study was designed for rapid diagnosis of Rotavirus antigen in stool sample by ICT (Immunochromatographic test) as well as to observe the seasonal variation of rotavirus infection. This cross sectional study was carried out in the department of Microbiology, Dhaka Medical College from January 2011 to December 2011. Eighty stool samples were collected from Dhaka Shishu Hospital and Dhaka Medical College Hospital. All samples were tested for rotavirus antigen by ICT. Among 80 patients, 42 (52.5%) samples were positive for rotavirus antigen. Among these 42 positive samples, 30 (71.43%) were from 0-12 months of age group, 10 (23.81%) from 13 to 24 months of age group and rest 2 (4.76%) from 25 to 36 months of age group. Rotavirus Ag was detected in stool samples from January to April and another peak episode from October to December. Considering the importance of Rotavirus associated diarrhea, rapid detection of Rotavirus infection in human is substantially needed and should be routinely practiced.DOI: http://dx.doi.org/10.3329/bjmm.v6i1.19354 Bangladesh J Med Microbiol 2012; 06(01): 11-13
