Sternostylus Baba, Ahyong & Schnabel 2018
No full textSternostylus Baba, Ahyong & Schnabel, 2018 Remarks. The genus Sternostylus, representing the family Sternostylidae, was established very recently based on the unique morphology of the sternal plastron, the proximity of third maxillipeds, being adjacent to each other, and the P2–4 dactyli ending in a spine that is not clearly demarcated from the remainder of the dactylus, and supported by the available molecular data (Baba et al. 2018).Published as part of Baba, Keiji & Wicksten, Mary K., 2019, Chirostyloidean squat lobsters (Crustacea: Decapoda: Anomura) from the Galapagos Islands, pp. 391-421 in Zootaxa 4564 (2) on page 418, DOI: 10.11646/zootaxa.4564.2.5, http://zenodo.org/record/258923
Heteroptychus Baba 2018
No full textGenus Heteroptychus Baba, 2018 Remarks. This genus was recently established for an aberrant group of species in the genus Uroptychus, which is characterized by a well-depressed carapace with laterally or posteriorly inclined antennae, P4 very short, especially the carpus being 0.3–0.5 × as long as the P3 carpus, and the sternal plastron differing between sexes: the female sternal plastron is unusual, strongly excavated on the posterior margin, with the median parts of sternites 5–7 absorbed into sternite 4 (the left and right parts of sternites 5–7 discontinuous, interrupted by loss of median parts). Including the two new species described below, Heteroptychus contains 11 species, one from the western Atlantic, eight from the Indo-West Pacific, and now two from the eastern Pacific. Morphological differences among species are very slight, but molecular data, where available, clearly separate some species (Baba 2018).Published as part of Baba, Keiji & Wicksten, Mary K., 2019, Chirostyloidean squat lobsters (Crustacea: Decapoda: Anomura) from the Galapagos Islands, pp. 391-421 in Zootaxa 4564 (2) on page 397, DOI: 10.11646/zootaxa.4564.2.5, http://zenodo.org/record/258923
Chinese literary works translated into Baba Malay: a bibliographical study
No full textAnalyses 68 unique titles of Baba translated works published between 1889 and 1950. The titles are held in the libraries of the University of Malaya (UM), Science University Malaysia (USM), National University of Malaysia (UKM), the Dewan Bahasa dan Pustaka (DBP), National University of Singapore (NUS), National Library of Singapore (NLS) and the British Library (BL). The results reveal three periods of active publication of Baba translated works. A total of 18 works were translated before World War I, followed by 10 just after the war, 39 titles were published before the break of the World War II and 1 was identified in 1950. There were 103 persons involved in the 68 translated works, some of whom are responsible for more than one title. The most prominent translators were Chan Kim Boon, Wan Boon Seng, Seow Chin San and Lee Seng Poh. Some of the translators were also be editors, illustrators or editors. There were 31 publishers and 21 printing presses involved, all were located in Singapore. The most active publishers were Wan Boon Seng, Kim Seck Chy Press and Nanyang Romanised Malay Book Co. The translated works mainly cover historical classical Chinese stories, chivalrous stories, romances, folklore and legends. The titles were priced between 10 cents to 2 dollars in Straits currency. The University of Malaya Library held the largest number of unique title (62) out of which 15 were unique titles
THE ANATOMY OF FAVORINUS JAPONICUS BABA (NUDIBRANCHIA-EOLIDOIDEA)
No full textFavorinus GRAY, 1850 is a splendid genus, the distinctive characters of which were introduced in parts by ALDER & HANCOCK, 1855, and somewhat more effectively by ODHNER, 1939 (see also MACNAE, 1954a, pp. 17-19). Eolis alba A. & H., 1844, Atlantic, forms the type of the genus. A series of species were added to this genus by the senior author (F. pacificus BABA, 1937; F. japonicus BABA, 1949; F. perfoliatus BABA, 1949; and F. mirabilis BABA, 1955), and it was revealed that the rhinophores in Favorinus are either simple, or bulbed, or even perfoliated according to different species. Here F. japonicus BABA was taken up for special study in anatomy, with the hope to understand the various genetic features more profoundly than before. Apparently this species is one of those nearest to the type of the genus, particularly in having bulbs on the mid-length of the rhinophores
BabA-mediated adherence of pediatric ulcerogenic <i>H. pylori</i> strains to gastric mucins at neutral and acidic pH
No full textHelicobacter pylori infection can result in non-ulcer dyspepsia (NUD), peptic ulcer disease (PUD), adenocarcinoma, and gastric lymphoma. H. pylori reside within the gastric mucus layer, mainly composed of mucins carrying an array of glycan structures that can serve as bacterial adhesion epitopes. The aim of the present study was to characterize the binding ability, adhesion modes, and growth of H. pylori strains from pediatric patients with NUD and PUD to gastric mucins. Our results showed an increased adhesion capacity of pediatric PUD H. pylori strains to human and rhesus monkey gastric mucins compared to the NUD strains both at neutral and acidic pH, regardless if the mucins were positive for Lewis b (Leb), Sialyl-Lewis x (SLex) or LacdiNAc. In addition to babA positive strains being more common among PUD associated strains, H. pylori babA positive strains bound more avidly to gastric mucins than NUD babA positive strains at acidic pH. Binding to Leb was higher among babA positive PUD H. pylori strains compared to NUD strains at neutral, but not acidic, pH. PUD derived babA-knockout mutants had attenuated binding to mucins and Leb at acidic and neutral pH, and to SLex and DNA at acidic pH. The results highlight the role of BabA-mediated adherence of pediatric ulcerogenic H. pylori strains, and points to a role for BabA in adhesion to charged structures at acidic pH, separate from its specific blood group binding activity.</p
The Baba Settlement
No full textThe unedited film footage shows the construction of the functionalist Baba settlement (Osada Baba), which was built in the area between the Church of St. Matthew (Kostel sv. Matěje) in Dejvice and the Baba ruins in 1932. The settlement's urban design was done by architect Pavel Janák. The construction site was visited by Prague Mayor Karel Baxa accompanied by architects Pavel Janák and Josef Fuchs, and publicist Stanislav Mojžíš-Lom. The segment includes wide shots of the construction site overlooking Prague and footage of the application of asphalt roofing on one of the houses
Boosting potato defence against late blight
No full textFor more than one century efforts has been made to obtain potato (Solanum tuberosum) cultivars resistant to late blight. However, introduced resistance has repeatedly been overcome by Phytophthora infestans (Mont) de Bary. Today late blight control is dependent on the frequent use of fungicides, but development of fungicide resistance and increasing fungicide restrictions by EU are of major concern. Methods with less fungicide requirement is therefore of crucial importance for a more environmentally sound and sustainable late blight control in the future.
In this study the potential of integrating BABA-induced resistance in existing late blight management with fungicides was investigated in field. The fungicide dose could be lowered with up to 25% when combined with BABA, without any decrease in late blight control or metabolic cost in terms of tuber yield. BABA was shown to directly activate basal defence responses and hormone signaling in potato. The BABA-induced hypersensitive-like lesions and major changes in the amino acid balance indicate that BABA induces resistance by stress imprinting.
Furthermore the potential of using a biosurfactant, produced by Psuedomonas koreensis strain 2.74, to control late blight in greenhouse was demonstrated. The biosurfactant was shown to have a direct effect on zoospores and also to induce PR-1 accumulation in the apoplast of potato leaves. Future experiments will reveal if the biosurfactant induces other defence mechanisms in potato.
This study demonstrated how integration of different control methods could lead to unchanged or even improved late blight control despite the decrease in fungicide dose

Remarks. Only two specimens referable to this genus are identified as new species, H. galapagos and H. nautilus (see below). These species share a non-articulated antennal scale, which links them to H. lemaitrei Baba, 2018 and H. claudeae Baba, 2018, both from the western Pacific. Heteroptychus galapagos n. sp. differs from H. lemaitrei Baba, 2018 in having two instead of only one protuberance on the carapace lateral margin, in having the rostrum horizontally directed straight forward rather than dorsally directed, in having the anterolateral spine of the carapace directed straight forward and dorsally instead of anteromesially and horizontally, in having the lateral orbital angle rounded instead of bearing a distinct spine, and in having the pterygostomian flap surface with two distinct ridges instead of being smooth without ridges. Heteroptychus claudeae has no protuberance on the carapace lateral margin, the anterolateral spine of the carapace closer to the lateral limit of the orbit, the rostrum more or less depressed distally rather than spiniform, the pterygostomian flap much lower in the posterior half (posterior height/anterior height, 0.1 versus 0.4). Morphological differences between H. galapagos and H. nautilus are outlined under the remarks of H. nautilus (see below). Distribution.
