Cover Image Telipogon peruvianus is a highly restricted Neotropical orchid species, endemic to the southern Peruvian Andes. It is only known from two localities, which are affected by anthropogenic disturbance. The present study investigated whether the restricted distribution of T. peruvianus has led to low genetic diversity and inbreeding, thus threatening its survival. https://doi.org/10.1111/1442-1984.12291

Peptoids belong to a class of sequence-controlled polymers containing N-alkylglycine units. Ren et al. use tandem mass spectrometry to characterize the fragmentation patterns of some singly and doubly protonated peptoids with one basic residue at different positions. Upon collision-induced dissociation, a charged peptoid dissociates into two sets of charged fragments: B-ions, containing the N-terminal residue (structure on the left); and Y-ions, containing the C-terminal residue (structure on the right). The Y-ions are of higher abundance than the B-ions, revealing that the C-terminal fragments have a higher affinity toward the charge carrier, the proton. (DOI: 10.1002/bip.23358 )
A high‐efficiency computer‐aided diagnostic model of ovarian cancer was developed, integrating SHG imaging technology for non‐invasive imaging of living tissue and machine learning method based on radiomics and TPOT. This model can rapidly, non‐destructively, and accurately perform ovarian cancer diagnosis and has great potential in improving diagnostic efficacy and efficiency of medical pathologists. Further details can be found in the article by Guangxing Wang, Yang Sun, Youting Chen, Qiqi Gao, Dongqing Peng, Hongxin Lin, Zhenlin Zhan, Zhiyi Liu, and Shuangmu Zhuo ( e202000050 ).
This study proposed a Sparse‐Graph Manifold Learning (SGML) method to balance the sparseness and morphology preserving for bioluminescence tomography reconstruction. It inherits the benefits of non‐convex sparsity constraint and dynamic Laplacian graph model. The results of numerical simulations and in vivo experiments demonstrate that the proposed method yields accurate and robust results in terms of tumor spatial location and morphology recovery. Further details can be found in the article by Hongbo Guo, Ling Gao, Jingjing Yu, et al. ( e201960218 )

Cover Photograph: Upper left: Newt (P. waltl) juveniles and Xenopus froglets were subjected to agarose-embedded heat-shock (AeHS) method. GFP expression was induced specifically in the regenerating limbs (see Matsubara et al. 86–93). Upper right: Schematic diagram of the intermittent hypoxia exposure model. Pimonidazole-positive cells were detected in the pulmonary tissues of Xenopus laevis during repeated dives, indicating tissue hypoxia (see Fujiyama, 94–99). Lower left: The intercalary element of Zhangixalus schlegelii (arrowheads). Such skeletal elements are seen between the terminal and subterminal phalanges of all the digits of arboreal frogs (see Nakanishi, 100–108). Lower right: Tetraspanin9 expressions in Xenopus laevis (above) and X. tropicalis embryo (below) hybridized in the same tube. (see Kuriyama and Tanaka, 109–119). Bottom right corner: A 48 hpf early four-armed pluteus taken through a confocal microscope. Catecholamine-positive cells are colored in yellow (see Kalachev and Tankovich, 120–131).
A type of compact and cost‐effective light‐sheet imaging device, termed sub‐voxel‐resolving light‐sheet add‐on module (SLAM), is developed to cooperate with conventional 2D epifluorescence microscope, allowing high‐contrast, resolution‐improved 3D imaging of various biological samples at high throughput. Further details can be found in the article by Fang Zhao, Yicong Yang, Yi Li, et al. ( e201960243 ).
