Ptisana soluta Murdock & Perrie 2023, comb. nov., stat. nov.
No full textPtisana soluta (Compton) Murdock & Perrie, comb. nov., stat. nov. (Figs 3; 5) Ptisana soluta (Compton) Murdock & Perrie comb. nov., stat. nov. differs from Ptisana attenuata (Labill.) Murdock in bearing leaves with smooth, mottled green-brown stipes, and laminae that are 3-pinnate proximally, 2-pinnate distally, and differs from Ptisana salicina (Sm.) Murdock in bearing synangia that are removed from the margin, and laminar division as previously described. Marattia smithii Mett. ex Kuhn forma soluta Compton, Journal of the Linnean Society, Botany 45: 456 (Compton 1922). — Type: New Caledonia. Ignambi, 1500 ft., 4.VIII.1914, Compton 1674 (holo-, BM [BM000787128]!). ETYMOLOGY. — Compton (1922) originally described this species as Marattia smithii Kuhn forma soluta Compton and noted the lamina character that distinguishes this taxon. The Latin “ soluta ” means “separate from adjacent parts, breaking up”, presumably in reference to its transition between 2- and 3-pinnate states. HABITAT AND DISTRIBUTION. — Based on available collections, Ptisana soluta comb. nov., stat. nov. is endemic to New Caledonia, where it is widespread but uncommon on Grande Terre. It is known from Mt. Ignambi and Mt. Panié in the northeast, near Canala in the central-east, and near Nouméa in the southwest (Fig. 4). One collection from Sommet Arago (Compton 1442, BM) may be this species, but was described as being from a population of 2-pinnate plants; this requires further investigation. Several collections note a (rain-) forest and/or mountain habitat, with recorded elevations ranging from 200 m to 800 m. Based on Fig. 4, it seems to be on non-ultramafic substrates, although it may come at least close to ultramafics on Koghis. At Koghis, P. soluta comb. nov., stat. nov. grows intermixed with P. attenuata and Angiopteris evecta. Additional study of the ecological range of P. soluta comb. nov., stat. nov., and how it may differ from P. attenuata, is needed. CONSERVATION ASSESSMENT. — We suggest that Ptisana soluta comb. nov., stat. nov. be ranked as Vulnerable (VU B1ab(i,i i,iii,iv,v)+2ab(i,ii,iii,iv,v), IUCN 2012), with this provisional until verified by the New Caledonia Plants Red List Authority. The estimates of 60 km 2 for area of occupancy and 4236 km 2 for extent of occurrence are well under the thresholds for criterion B of the Vulnerable category. The subcriteria 1b and 2b are met because of ongoing, substantive predation by rusa deer and feral pigs, as is the case with P. attenuata (Endemia Red List Authority 2022). The subcriteria 1a and 2a both invoke “no more than 10 locations”. The exact number of locations is unclear, particularly with the imprecision of earlier collections, but given the mobility of the deer and pig threats, known locations could be defined as: 1-2 in the southwest, one in the central-east, and 2-4 in the northeast (see Fig. 4). Ptisana soluta comb. nov., stat. nov. is unprotected by legislation, but occurs within reserves at Thy Valley and Mt. Panié. The priority for its management should be searching for new sites and surveying known localities, particularly the accessible Koghis and also Ignambi, where Compton (1922) said this form was “abundant”. DESCRIPTION Fronds 3-pinnate proximally, transitioning to 2-pinnate distally, at least 4 m long, bearing 4-6 pairs of opposite pinnae on mature fronds, the terminal pair forking at the frond apex. Stipe circular in cross-section, smooth, mottled green-dark brown, subtended by paired stipules, round, shallowly divided to nearly entire with ragged margins. Swollen pulvini present at the base of all segments, green, smooth. Ultimate segments 35-104 mm long × 6.5-19.1 mm wide on 3-pinnate portions, 163-295 mm long × 13.7-35.6 mm wide on 2-pinnate portions, oblong with acuminate apices. Laminae dark green above, lighter below, herbaceous-coriaceous, with occasional ciliate scales abaxially along veins and midribs. Veins free, c. 2 mm apart, occasionally dividing once. Leaf margin sub-entire-minutely serrate, more clearly serrate near apex. Synangia green when immature, tan-brown after opening, one per vein, submarginal, set back from leaf margin by 1-3 mm, 2-3.5 mm long × c. 1 mm wide, longer and with more locules on larger segments, receptacles bearing short, branched, uniseriate hairs.

Applications of AFM in pharmaceutical sciences
No full textAtomic force microscopy (AFM) is a high-resolution imaging technique that uses a small probe (tip and cantilever) to provide topographical information on surfaces in air or in liquid media. By pushing the tip into the surface or by pulling it away, nanomechanical data such as compliance (stiffness, Young’s Modulus) or adhesion, respectively, may be obtained and can also be presented visually in the form of maps displayed alongside topography images. This chapter outlines the principles of operation of AFM, describing some of the important imaging modes and then focuses on the use of the technique for pharmaceutical research. Areas include tablet coating and dissolution, crystal growth and polymorphism, particles and fibres, nanomedicine, nanotoxicology, drug-protein and protein-protein interactions, live cells, bacterial biofilms and viruses. Specific examples include mapping of ligand-receptor binding on cell surfaces, studies of protein-protein interactions to provide kinetic information and the potential of AFM to be used as an early diagnostic tool for cancer and other diseases. Many of these reported investigations are from 2011-2014, both from the literature and a few selected studies from the authors’ laboratories

От поэтики литературы к истории крестьянства: мои ранние приключения в области русистики
No full textThe article was submitted on 30.01.2015.The Editorial Board of the journal is rightly proud that it managed to persuade Professor Maureen Perrie, the eminent British historian of Russia, to write this memoir, intriguingly entitled ‘From Poetry to Peasantry: my Early Adventures in Russian Studies’. The memoir is written with such candour, and in such a lively and entertaining style, that its appeal will extend beyond specialists in the humanities. The reader is presented with a portrait of an entire generation, with its insights and its delusions, its loyalty to its parents’ moral code and its aspiration towards new visions of humanity. Maureen Perrie’s remarkable memory for detail enables her to create a complex and dynamic picture of the attitude of British society towards Russia, of cultural interactions and the cruel political prejudice that played such a pernicious role. At the same time we have a valuable account of her youthful enthusiasms, heartfelt experiences and the role of personal relationships in her development as a historian. The author followed a complex path, beginning with an interest in Russian literature and the Symbolists (her favourite poet was Alexander Blok), and leading on to research on the Russian peasantry, pretenderism and the Russian monarchy. This trajectory provides evidence of her inquiring mind and her desire to get to the very heart of a phenomenon – because a true understanding of Russia involves first and foremost an understanding of the patriarchal mindset, the peasant world, popular utopias and the cruelty of the regime towards its own people. Maureen Perrie has brilliantly succeeded in her task. Her publications make a major contribution to international Russian Studies; and this autobiographical essay, which is so revealing of the author’s personality, provides entertaining and moving reading for all lovers of Russian culture. Translated by Elena Galitsyna.Редколлегия журнала по праву гордится тем, что ей удалось заинтересовать выдающегося английского профессора истории России Морин Перри предложением написать воспоминания, интригующе озаглавленные «От поэтики литературы к истории крестьянства: мои ранние приключения в области русистики». Воспоминания написаны с таким доверительным чувством, настолько живо и занимательно, что должны привлечь внимание не только специалистов в сфере гуманитарной науки. Перед читателем возникает портрет целого поколения с его проницательностью и заблуждениями, верностью родительской морали и устремлением к новым горизонтам человечности. Удивительная память Морин Перри на детали позволяет воспроизвести объемную и динамичную картину отношения британского общества к России, культурных взаимодействий и политической античеловеческой ангажированности, играющей губительную роль. Вместе с тем перед нами драгоценные страницы, описывающие увлечения юности, тонкие переживания, роль человеческих взаимоотношений в формировании историка. Проделанный автором непростой путь, начавшийся с интереса к русской литературе и младосимволистам (любимый поэт – А. Блок) и приведший к изучению русского крестьянства, самозванчества и российской монархии, свидетельствует о пытливости ума и стремлении проникнуть в самую глубь явления, потому что действительно понять Россию – это, в первую очередь, понять патриархальное сознание, крестьянский мир, народные утопии и жестокость режима к своему народу. Это блестяще удалось Морин Перри. Ее работы являются важной страницей мировой русистики, а ее биографические заметки, раскрывающие личность автора, представляют занимательное и эмоциональное чтение для всех любящих русскую культуру

The relationships of Microsorum (Polypodiaceae) species occurring in New Zealand
No full textRelationships of the three species of Microsorum occurring in New Zealand, M. novae-zealandiae, M pustulatum, and M scandens, were explored using evidence from four chloroplast genomic markers: rbcL, rps4, rps4-trnS intergenic spacer, and trnL-F intergenic spacer. All three species were nested in a strongly supported lecanopteroid clade together with the ant-fern genus Lecanopteris and several species accepted as belonging to the polyphyletic genus Microsorum. M scandens is sister to M varians from New Caledonia, and in turn both are sister to M linguiforme. M novae-zealandiae and M. pustulatum form a clade together with the New Caledonian endemic M viellardii. Support from morphological features is discussed, as is the possibility of a diversification of the lecanopteroids in Eastern Malesia and/or adjacent areas to the south after the collision of Australia and south-east Asia
