Dengue encephalitis (DE) is characterized as unusual presentation of dengue infection. Despite the reports that DE accounts for only 1-5% of dengue cases, this disease tends to be increasingly reported to threaten global human health throughout dengue endemic areas particularly in Southeast Asia. The molecular information of clinically characterized, neurotropic dengue virus (DENV) in human beings is extremely scarce despite it playing an important role in deciphering the pathogenesis of dengue-related neurological cases. Here we report a case of DE caused by DENV3 genotype III in a male patient with atypical symptoms of DENV infection in Hai Phong, Vietnam in 2013. The virus isolated from the cerebrospinal fluid of this case-patient was closely related to DENV3 genotype III strains isolated from serum of two other patients, who manifested classical dengue in the same year and residing in the same area as the case-patient. It is noteworthy to mention that in 2013, DENV3 genotype III was detected for the first time in Vietnam.

A new class of non facet-to-facet random tessellations in three-dimensional space is introduced -the so-called column tessellations. The spatial construction is based on a stationary planar tessellation; each cell of the spatial tessellation is a prism whose base facet is congruent to a cell of the planar tessellation. Thus intensities and various mean values of the spatial tessellation can be calculated from suitably chosen parameters of the planar tessellation.Keywords: combinatorial topology, random tessellations, stochastic geometry. THE CONTEXT FOR OUR NEW MODELRandom tessellations are classical structures considered by stochastic geometers. Two standard models are the Poisson hyperplane and Poisson Voronoi tessellations (Schneider and Weil, 2008;Chiu et al., 2013). In the planar case these tessellations are side-to-side, that is, each side of a polygonal tessellation cell coincides with a side of a neighbouring cell. In their three dimensional versions they are facetto-facet, meaning that each facet of a polyhedral cell coincides with a facet of a neighbouring cell.In recent years there has been a growing interest in tessellation models that do not have the stated coincidence for all sides or facets. A first systematic study of the effects when a three-dimensional tessellation is not facet-to-facet is given in Weiss and Cowan (2011). A recent study presented in Cowan and Thäle (2014) looks in depth at the planar case, building on results from the 1970s when non side-toside tessellations first attracted attention.Tessellations of that kind arise for example by cell division. Among these models, the iteration stable or STIT tessellation is of particular interest because of the number of analytically available results (Nagel and Weiss, 2005;Mecke et al., 2008;Thäle et al., 2012;Cowan, 2013;Thäle and Weiss, 2013, and the references therein). It serves as a reference model for geological crack and fissure structures (Mosser and Matthäi, 2014) and might have application in the process of biological cell division. The development of new model classes is important for further applications to random structures in materials science, geology and biology -and the current paper contributes to that aim.We consider a new class of non facet-to-facet spatial tessellations, whose construction is based on a stationary planar tessellation Y having convex polygonal cells. From each polygonal cell z of Y we form an infinite column perpendicular to the plane E in which Y lies. Any cross-section of the column parallel to E is congruent to z. To create a spatial tessellation, each infinite column is intersected by many such cross-sections, thereby dividing the column into cells. The spatial cells which arise are prisms and their polygonal base facets (located at the cross-sections) are translations (in the third dimension orthogonal to E ) of the cells of Y . The resulting three-dimensional tessellation Y is called a column tessellation. Column tessellations could be useful to describe crack structures in geology, as for e...

The study aimed to evaluate the influence of various parameters of the blanching and drying condition of small shrimp (Acetes) on some product quality parameters. Some criteria were assessed, such as salt content, astaxanthin content (ATC), and color of small shrimp. The results showed that the blanching time significantly affected the salt content. When increasing the blanching time, the salt content was found to increase from 17.35 ± 2.48 mg/g DW to 39.51 ± 0.45 mg/g DW. The astaxanthin content achieved the highest value (0.026 ± 0.001 mg/g DW) in a 2% salt solution. The study showed that the blanching and drying processes significantly affected the salt content, astaxanthin, and color of the small shrimp, and the optimized temperatures for blanching and drying were 70°C and 60°C, respectively.
