Published: February 2019

AbstractObjectiveIn an effort to provide further evidence for the validity of the Lung Cancer Stigma Inventory (LCSI), this paper examined group differences in lung cancer stigma for patients who report clinically significant depressive symptoms and established a suggested scoring benchmark to identify patients with clinically meaningful levels of lung cancer stigma.MethodsPatients (N = 231) who were diagnosed with lung cancer and treated within the past 12 months at one of two National Cancer Institute (NCI)‐designated Cancer Centers located in the northeast and southern parts of the United States completed a single battery of questionnaires examining lung cancer stigma and depressed mood. Group differences, bivariate correlations, and receiver operating characteristic (ROC) analyses were conducted.ResultsSlightly more than a third of patients (35.9%) reported an elevated level of depression. There was a significant correlation (r = 0.44) between lung cancer stigma and depressive mood. The ROC curve analysis indicated an area under curve (AUC) of 0.71. A LCSI cutoff score of 37.5 yielded the optimal ratio of sensitivity (0.93) to specificity (0.70) for identifying patients with clinically meaningful lung cancer stigma.ConclusionsConsistent with prior work, lung cancer stigma, as measured by the LCSI, was found to be moderately associated with depressed mood. Clinical investigators may use an LCSI total score above 37.5 (ie, greater than or equal to 38 on the LCSI scale of integer scores) as a clinical threshold for identifying patients who may be experiencing clinically meaningful stigma and may benefit from stigma‐reducing interventions.

AbstractResearch on the sustainable livelihoods of rural households is of great significance in solving rural poverty and promoting the transfer of rural land management rights, which are necessary for realizing better livelihoods and sustainable development. In this study, we used a partial least squares‐structural equation model to systematically explain the interacting mechanisms of livelihood capital, livelihood strategy, and agricultural land transfer in the mountainous and hilly regions of Sichuan, China, based on survey data from 240 rural households. The results are as follows: (a) land transfer characteristics were negatively affected by farmers' livelihood strategies. The higher the proportion of the nonagricultural labor force/livelihood diversity index, the greater the possibility to roll‐out plots. The lower the proportion of the nonagricultural labor force/livelihood diversity index, the greater the possibility to roll‐in plots. (b) Natural capital was directly and negatively affected by livelihood strategy, and indirectly and positively affected by land transfer. (c) Financial capital insurance was indirectly and positively affected by livelihood strategy. Financial capital insurance had a mediating effect: land transfer not only had a direct negative effect on it but also had an indirect effect through natural capital. (d) Financial capital income was directly positively affected by financial capital insurance, and indirectly negatively affected by land transfer and natural capital. Financial capital income had a mediating effect, and livelihood strategy not only had a direct positive effect on it but also had an indirect positive effect via human capital. (e) Physical capital and human capital were directly positively affected by livelihood strategy. (f) Certain moderating effects were observed. Nonagriculture‐dependent farmers had higher physical capital, greater human capital, higher financial capital income, and more area of roll‐out plots than agriculture‐dependent farmers. This study provides theoretical guidance for the formulation of policies for livelihood improvement and sustainable development.
Carbon Dots for In Vivo Bioimaging and Theranostics
Authors: Du Jianjun , Xu Ning , Fan Jiangli , Sun Wen , Peng Xiaojun 
Published: February 2019

AbstractCarbon dots (CDs), a kind of carbon material discovered accidentally, exhibit unexpected advantages in fluorescence imaging/sensing such as photostability, biocompatibility, and low toxicity. For emerging theranostics, an interdiscipline created by integrating therapy and diagnostics, CDs are good candidates when they are combined with targeted chemo/gene/photodynamic/photothermal therapeutic moieties. Here, the development of CDs in nanomedicine is reviewed from their use as original imaging agents and/or drug carriers to multifunctional theranostic systems. Finally, the challenges and prospects of the next‐generation of CD‐based theranostics for clinical applications are also discussed.

Abstract
Poor cell homing limits the efficacy of cardiac cellular therapy. The homing peptide, cysteine-arginine-glutamic acid-lysine-alanine (CREKA), targets fibrin effectively which is involved in the repair process of tissue injury. Here, we assessed if CREKA-modified stem cells had enhanced fibrin-mediated homing ability resulting in better functional recovery and structural preservation in a rat myocardial injury model. CREKA-modified mesenchymal stem cells (CREKA-MSCs) were obtained via membrane fusion with CREKA-modified liposomes. The fibrin targeting ability of CREKA-MSCs was examined both in vitro and in vivo. Under both static and flow conditions in vitro, CREKA significantly enhanced MSCs binding ability to fibrin clots (2.6- and 2.3-fold, respectively). CREKA-MSCs showed 6.5-fold higher accumulation than unmodified MSCs in injured rat myocardium one day after administration, resulting in better structural preservation and functional recovery. Fibrin is, therefore, a novel target for enhancing homing of transplanted cells to injured myocardium, and the delivery system of fibrin-targeting is on behalf of a universalizable platform technology for regenerative medicine.

High epizoochorous specialization and low DNA sequence divergence in Mediterranean Cynoglossum (Boraginaceae): Evidence from fruit traits and ITS region
Authors: Selvi Federico , Coppi Andrea , Cecchi Lorenzo 
Published: February 2019

AbstractFruit morpho‐anatomy and DNA sequence diversity in Euro‐Mediterranean taxa of Cynoglossum and the closely related genera Solenanthus and Pardoglossum were analysed to assess the structural traits that promote dispersal through transport via the fur of mammals, and to evaluate the phylogenetic value of carpological variation in the group. Electron and light microscopy showed striking epizoochorous adaptations in characters of the pluricellular projections of the epicarp (glo chids), such as multiple apiacl hooks, conical shape, and finely tuberculate surface, as well as the heavy mineralization of the cell walls with especially silicon and calcium revealed by X‐ray microanalysis. The attachment potential of nutlets to sheep fleece, estimated through a General Linear Model, was species‐specific and relatively high in the taxa with small and light diaspores (>60%). ITS sequences from 29 specific and infraspecific accessions were poorly variable, with pairwise genetic distances ranging from 0.002 to 0.097 (mean 0.044). A comparative analysis of ITS sequence diversity in relation to the differ ent dispersal strategies in the four main Boraginaceae tribes revealed substantially higher levels of variation and interspecific genetic distances in the non‐epizoochorous groups, including the Cynoglosseae genera Myosotis and Omphalodes. Bayesian and maximum parsimony tree construction suggested paraphyly of Cynoglossum due to the nested position of Solenanthus apenninus and Pardoglossum. Species‐level relationships remained largely unresolved, preventing an estimation of the phylogenetic significance of fruit characters. Rapid spread across the Mediterranean region via epizoochory by wild mammals is possibly the primary cause for the lack of genetic divergence among species. During the Holocene, nomadic and transhumant pasture by domesticated herbivores has likely contributed to further spreading and mixing of previously isolated taxa, possibly causing events of homoploid hybridization and introgression. More variable molecular markers should be tested to better understand the impact of these processes in the evolutionary history of Cynoglossum and to solve relationships within Cynoglosseae.
Major speciation accompanied the dispersal of Vireya Rhododendrons (Ericaceae, Rhododendron sect. Schistanthe) through the Malayan archipelago: Evidence from nuclear gene sequences
Authors: Goetsch Loretta A. , Craven Lyn A. , Hall Benjamin D. 
Published: February 2019

AbstractThe species within Rhododendron sect. Schistanthe (= sect. Vireya), a taxon unique for its tropical habitat, distinctive leaf scales, and tailed seeds, have diversified greatly in morphological features. The section contains over 300 species, occurring mainly on the Malay Peninsula, New Guinea, and the islands between. An analysis based on the combined sequences of three nuclear genes supports a phylogeny in which sect. Schistanthe (less R. santapaui) is monophyletic, with well‐defined clades corresponding to subsections Euvireya, Malayovireya, Pseudovireya, and Discovireya. Within subsect. Euvireya, molecular‐phylogenetic groupings follow geography more closely than traditional taxonomic groupings based upon morphology. One of the two most derived clades contains exclusively species from New Guinea, Australia, and the Solomon Islands. The results are consistent with a stepwise phylogeographic history of sect. Schistanthe, beginning in Asia, proceeding eastward and reaching New Guinea within the last 15 Ma, when movement of the Australian tectonic plate brought New Guinea into the Malesian domain.
Moranopteris: A new Neotropical genus of grammitid ferns (Polypodiaceae) segregated from Asian Micropolypodium

Published: February 2019

AbstractMoranopteris, a new genus of grammitid ferns here described, is segregated from Micropolypodium on the basis of molecular phylogenetic analyses (plastid sequences including atpB, rbcL, and trnL‐trnF) and morphological characters. Bayesian and maximum parsimony analyses support Moranopteris as sister clade to a group that includes Micropolypodium s.str. and 11 or 12 other genera, mostly from the Old World. A morphological synapomorphy for the species of Moranopteris is the presence of minute and slightly catenate branched hairs (with or without a setiform branch) and sometimes unbranched hairs occurring together on the stipes, costae, and laminar tissues abaxially. In contrast, Micropolypodium s.str. has only minute, catenate, and unbranched hairs borne on the same parts of the leaves. The new genus Moranopteris comprises 28 species—including two new species here described, M. rupicola and M. simplex—and one hybrid, occurring in the Neotropics. The 27 necessary new combinations are here proposed. Our results suggest that Micropolypodium is confined to eastern Asia.

Published: February 2019

AbstractThe classification of Bruniaceae is reviewed based on molecular (matK, ITS, rbcL) and morphological data, and the tribes and genera are redefined as monophyletic, morphologically diagnosable lineages. The family is subdivided into three tribes and six genera with 81 accepted species, Linconieae (Linconia), Audouinieae (Audounia [incl. Tittmannia], Thamnea [incl. Pseudobaeckea teres]), and Brunieae (Berzelia [incl. Brunia p.p.], Staavia [incl. Raspalia staavioides], and Brunia [incl. Nebelia, Pseudobaeckea p.p., Raspalia p.p., Lonchostoma, Mniothamnea]). A key for the new classification, a short description of each genus and an updated nomenclature of all the species are provided. Two new tribes are described and thirty‐eight new combinations and names are provided.
Parashorea chinensis Wang Hsie and P. chinensis var. kwangsiensis Lin Chi: Two exceptional cases of names with a corporate authorship
Authors: Shui Yu-Min , Wen Jun , Chen Wen-Hong 
Published: February 2019

AbstractParashorea chinensis Wang Hsie and Parashorea chinensis var. kwangsiensis Lin Chi (Dipterocarpaceae) are economically and ecologically important tree taxa in China and Vietnam. Their authorship should be "Wang Hsie" and "Lin Chi", respectively, which represent two logograms of working groups that existed in the particular circumstances from the 1960s to the 1970s in China. The author of Parashorea chinensis has sometimes been designated inappropriately as H. Wang. We herein discuss in detail these two unique cases in the context of the International Code of Botanical Nomenclature.
Valid publication of names in Astereae originally proposed in 1990 in a University of Munich dissertation

Published: February 2019

AbstractThe new species names Mairia petiolata, Zyrphelis capensis, Z. glabra, Z. glandulosa, Z. grauii, Z. macrocarpa, Z. nervosa, Z. spathulata, the new subspecies names Mairia hirsuta subsp. robusta, Zyrphelis ecklonis subsp. oligocephala, Z. ecklonis subsp. strictifolia, Z. microcephala subsp. foliosa, Z. microcephala subsp. glandulosa and the new combinations Zyrphelis ciliaris, Z. ciliaris subsp. angustifolia, Z. ciliaris subsp. hirsuta, Z. decumbens, Z. fruticosa, Z. gracilis, Zyrphelis sect. Gymnostephium, Z. leiocarpa, Z. levis, Z. montana, Z. monticola, and Z. outeniquae are validly published. These names originally appeared in the Ph. D. thesis of the second author, Ursula Zinnecker‐Wiegand, submitted to the University of Munich, Germany, in 1990. Being printed and distributed to over 50 libraries, this thesis met the formal requirements for effective publication of the International Code of Botanical Nomenclature then in force, but it is no longer effectively published as a result of a retroactive change in the rules adopted at the International Botanical Congress in Vienna in 2005. As result, the new names appearing in the thesis were not validly published and they are validated here.
Molecular phylogeography of Thymus herba-barona (Lamiaceae): Insight into the evolutionary history of the flora of the western Mediterranean islands

Published: February 2019

AbstractThymus herba‐barona is endemic to Majorca, Corsica, and Sardinia. In order to gain insight into its evolutionary history, we examined the genetic diversity and phylogeography of the species using sequences of the trnT‐trnL intergenic spacer from 106 individuals belonging to 15 populations. We detected high within‐species genetic diversity and strong among‐population differentiation, but no evidence for phylogeographic structure. A haplotype network supported the occurrence of three main clades, the ancestral one being geographically restricted to the Gennargentu massif in Sardinia, while the two derived ones were relatively widespread. Coalescent‐based analyses indicated deep divergence times and limited ongoing gene flow between major clades. The inferred evolutionary history of the species involved an early range expansion followed by successive fragmentation episodes, probably related to progressive climatic aridification since the Pliocene (3.2 Ma). Our data suggest that long‐distance dispersal events played a minor role in the evolutionary history of the species. The exact origin of the species remains unclear. The highly structured pattern of genetic variability detected suggests that random genetic drift played a major role in structuring genetic variation in this endemic plant. The cytogenetic evidence does not support the proposed recognition of three taxonomic entities within T. herba‐barona based on morphological discontinuities associated with different ploidy levels.
Biosystematic studies on the family Tofieldiaceae III. Classification of Tofieldia nuda into three species and three varieties

Published: February 2019

AbstractIn order to reexamine the taxonomic coherence of Tofieldia nuda, which shows wide morphological variation within the species, we analysed sequences of plastid trnK, trnL, and trnL‐F and nuclear ITS of T. nuda and seven further species of Tofieldia. We found that T. nuda contains three different lineages supported with 99% or 100% bootstrap value: one lineage sister to T. coccinea (100%), one linage sister to the Chinese species T. divergens and T. thibetica (98%–100%), and a third lineage sister to the second lineage plus T. divergens and T. thibetica (99%–100%). As the wide morphological gaps among T. nuda, T. coccinea, T. divergens, and T. thibetica prevent us from considering them as conspecific with one another, the three lineages of T. nuda are regarded as different at the species level. The first lineage corresponds to T. nuda s.str., the second to T. furusei (formerly T. nuda var. furusei), and the third to T. yoshiiana, often considered a synonym of T. nuda. Tofieldia yoshiiana is further divided into three varieties, var. yoshiiana, var. kanwonensis comb. nov. and var. hyugaensis var. nov. A key to the three species and varieties is provided.
Morphology‐based phylogenetic binning of the lichen genera Graphis and Allographa (Ascomycota: Graphidaceae) using molecular site weight calibration
Authors: Berger Simon A. , Stamatakis Alexandros , Lücking Robert 
Published: February 2019

AbstractDespite their potential shortcomings for phylogenetic inference, sometimes only morphological data are available for systematic classification. Computational methods are used to determine morphological site patterns congruent with the molecular tree in order to improve the accuracy of the classification of taxa for which only morphological data exist. Here, we used molecular site weight calibration as implemented in RAxML to weight morphological characters based on their distribution on a maximum likelihood tree inferred from molecular data. We subsequently conducted morphology‐based 'phylogenetic binning' (= assignment of morphologically defined taxa that lack molecular data to branches of the molecular reference tree) based on the morphology of the taxa included in the tree. We applied this methodology to the lichen genus Graphis s.l. (Ascomycota: Ostropales: Graphidaceae), which was recently shown to represent two separate, distantly related lineages, Graphis s.str. and Allographa. Of 313 species of Graphis and Allographa included in the study, 16 were represented by molecular sequence data and morphology, and 297 by morphology only. Using maximum likelihood and maximum parsimony site weight calibration and morphology‐based phylogenetic binning, 281–290 of the 297 species represented by morphological data only could be assigned to either Graphis or Allographa with strong support (90%–100%). Two species, G. saxiseda and G. evirescens, were found to represent species of the unrelated genus Carbacanthographis. Our results showed that assignment of taxa to clades based on morphological data only substantially improved with molecular site weight calibration. Both molecular site weight calibration and branch assignment to the molecular reference tree are implemented in the RAxML v.7.2.6 Windows executable and the RAxML v.7.2.8 open‐source code.
Revised lectotypification of Reseda glauca L. (Resedaceae)
Authors: Martín-Bravo Santiago , Jiménez-Mejías Pedro , Jarvis Charles E. 
Published: February 2019

AbstractThe currently accepted lectotype (Herb. Linn. No. 629.4, LINN) of Reseda glauca L. is identifiable as the related species, R. virgata Boiss. & Reuter. The specimen, collected by Löfling in central Spain, was not explicitly cited in Linnaeus's protologue, in contrast to a specimen (at UPS) collected by Burser in the Pyrenees and identifiable as R. glauca of usage. In accordance with Art. 9.10 of the ICBN, we reject the choice of 629.4 (LINN) as lectotype and we designate Burser's specimen as the lectotype of R. glauca L. in its place. This type choice maintains the traditional and current usage of this well‐known and widely used Linnaean name.
Revised lectotypification of Spartium scoparium L. (Fabaceae)
Authors: Auvray Gaëlle , Malécot Valéry 
Published: February 2019

AbstractThe currently accepted lectotype of the Linnaean species Spartium scoparium is a specimen of Cytisus arboreus (Desf.) DC. This lectotype is here superseded in favour of another specimen in the Linnaean collection on the grounds of conflict with the protologue. The current name for the species known as Cytisus scoparius (L.) Link can therefore be maintained.
The valid publication of the name Euaraliopsis (Araliaceae)
Authors: Deng Yun-Fei 
Published: February 2019

AbstractEuaraliopsis was first published by Hutchinson in 1967 who intended it to be a replacement name for "Araliopsis Kurz", which was not, however, a validly published name. As no Latin diagnosis was provided by Hutchinson, he did not validly publish Euaraliopsis. The name was, however, validly published inadvertently through a descriptio generico‐specifico when the new species Euaraliopsis moumingensis Y.R. Ling was described. The correct place of publication, authorship and typification are given for all validly published names in Euaraliopsis, generally considered a synonym of Brassaiopsis.
Changes to publication requirements made at the XVIII International Botanical Congress in Melbourne: What does e‐publication mean for you?
Authors: Knapp Sandra , McNeill John , Turland Nicholas J. 
Published: February 2019

AbstractChanges to the International Code of Botanical Nomenclature are decided on every six years at Nomenclature Sections associated with International Botanical Congresses (IBC). The XVIII IBC was held in Melbourne, Australia; the Nomenclature Section met from 18 to 22 July 2011 and its decisions were accepted by the Congress at its plenary session on 30 July. Several important changes were made to the Code as a result of this meeting that will affect publication of new names. Two of these changes will come into effect on 1 January 2012, some months before the Melbourne Code is published. Electronic material published online in Portable Document Format (PDF) with an International Standard Serial Number (ISSN) or an International Standard Book Number (ISBN) will constitute effective publication, and the requirement for a Latin description or diagnosis for names of new taxa will be changed to a requirement for a description or diagnosis in either Latin or English. In addition, effective from 1 January 2013, new names of organisms treated as fungi must, in order to be validly published, include in the protologue (everything associated with a name at its valid publication) the citation of an identifier issued by a recognized repository (e.g., MycoBank). Draft text of the new articles dealing with electronic publication is provided and best practice is outlined.
