The colon is an unusual site of intestinal atresia. Colonic atresia is subdivided into three phenotypes. Type III is the most common phenotype, where the proximal and distal blind sacs are not connected. Here, we report on the presence of colonic atresia with an “inverse apple-peel” appearance in a neonate with gastroschisis. The lack of mesenteric fixation of the entire small intestine, including the proximal colon, and the twisting around the vascular axis of the superior mesenteric artery led to intrauterine volvulus and hemorrhagic infarction of the ileocolic bowel at 34 weeks of gestation. According to the current nomenclature for small bowel atresia, we introduce type IIIB into the current colonic atresia classification. The occurrence of type IIIB has been mentioned in the literature, but no single cases have been reported until now. Patients with this type of atresia are predisposed to the loss of the ileocecal region.

Plants respond to drought stress with different physical manners, such as morphology and color of leaves. Thus, plants can be considered as a sort of living-sensors for monitoring dynamic of soil water content or the stored water in plant body. Because of difficulty to identify the early wilting symptom of plants from the results in 2D （two-dimension） space, this paper presented a preliminary study with 3D （three-dimension）-based image, in which a laser scanner was used for achieving the morphological information of zucchini （Cucurbita pepo） leaves. Moreover, a leaf wilting index （DLWIF） was defined by fractal dimension. The experiment consisted of phase-1 for observing the temporal variation of DLWIF and phase-2 for the validation of this index. During the experiment, air temperature, luminous intensity, and volumetric soil water contents （VSWC） were simultaneously recorded over time. The results of both phases fitted the bisector （line： 1：1） with R2=0.903 and REMS=0.155. More significantly, the influence of VSWC with three levels （0.22, 0.30, and 0.36 cm3 cm-3） on the response of plant samples to drought stress was observed from separated traces of DLWIF. In brief, two conclusions have been made：（i） the laser scanner is an effective tool for the non-contact detection of morphological wilting of plants, and （ii） defined DLWIF can be a promising indicator for a category of plants like zucchini.

Cytokinins are N^6-substituted adenine derivatives that are involved in the regulation of numerous aspects of plant growth and development. These include the control of cell division, leaf senescence, apical dominance, sink^source relationship, vascular and embryonic development, and apical meristem activity （Kieber and Schaller, 2014）. In addition, there is increasing evidence for the function of cytokinins in abiotic stress responses （Zwack and Rashotte, 2015）.

We examine the meandering instability for prismatic lattices formed from triangles,squares and hexagons using a nearest neighbor kinetic Monte Carlo *** the first two cases,which are Bravais lattices,we find that facets with the orientation favored in the equilibrium shape of isolated islands are most prone to this instability,while the analogous facet for the hexagonal lattice is the least *** argue that this is due to a significant difference in the reconstructed/equilibrium versus the non-reconstructed edge energy for non-Bravais ***/edge energy is typically modeled as a single-valued function of *** put forward a simple geometric argument that suggests this picture is inadequate for crystals with a non-Bravais lattice *** the case of a hexagonally structured lattice,our arguments indicate that the non-reconstructed edge energy can be viewed as both discontinuous and multi-valued for a subset of orientations that are commensurate with the crystal *** support these conclusions with density functional theory calculations that also reveal multivalued surface energies for the set of singular orientations.
