Impaired neural development in a zebrafish model for lowe syndrome
No full textLowe syndrome, which is characterized by defects in the central nervous system, eyes and kidneys, is caused by mutation of the phosphoinositide 5-phosphatase OCRL1. The mechanisms by which loss of OCRL1 leads to the phenotypic manifestations of Lowe syndrome are currently unclear, in part, owing to the lack of an animal model that recapitulates the disease phenotype. Here, we describe a zebrafish model for Lowe syndrome using stable and transient suppression of OCRL1 expression. Deficiency of OCRL1, which is enriched in the brain, leads to neurological defects similar to those reported in Lowe syndrome patients, namely increased susceptibility to heat-induced seizures and cystic brain lesions. In OCRL1-deficient embryos, Akt signalling is reduced and there is both increased apoptosis and reduced proliferation, most strikingly in the neural tissue. Rescue experiments indicate that catalytic activity and binding to the vesicle coat protein clathrin are essential for OCRL1 function in these processes. Our results indicate a novel role for OCRL1 in neural development, and support a model whereby dysregulation of phosphoinositide metabolism and clathrin-mediated membrane traffic leads to the neurological symptoms of Lowe syndrome. © The Author 2011.

I remember living at Seabrook, 1945-1953
No full textIn this "I remember" memoir, Ann Mariko Lowe recalls life at Seabrook, which introduced her to many new experiences, including Halloween traditions. She remembers the living conditions in the dorms at Seabrook, where there was little privacy, and poor facilities. Afterwards, her family moved to the apartments, where they were able to form close bonds with other Japanese families. This was especially helpful with expenses. Ann also played basketball at the Community Center, attended Bible study classes, and was a student at Seabrook School. The Seabrook Educational and Cultural Center has been soliciting current and past residents of Seabrook Farms for an "I remember" project. Residents are asked to create narratives regarding their experiences at Seabrook Farms. These memories help preserve the history and multi-cultural heritage of Seabrook Farms

TYPE LOCALITY AND HOLOTYPE DEPOSITORY. Eritrea, Chenafena; MZUT. MATERIAL EXAMINED. Eritrea, Chenafena (14.786N 39.018E), 1♀ (holotype), MZUT; Filfil, Salamuna river, 15°36'34.6"N 38°57'22.8"E, 817 m a.s.l., 3.-4.XI.2015, (Figs. 224–225, Locality No. 15 EH), 3♂ 3♀1♀ im.3juvs. (No. 876, Figs. 28, 36, 219–223, 226–244, 258–251, 258–259), leg. F. Kovařík, FKCP. DIAGNOSIS. Total length of adult males 32–35 mm, adult females 46–52 mm. Coloration yellowish brown to grey with darker markings, chelicerae yellow without or with traces of reticulation. Pedipalp chela manus much wider in male than female, chela length/width ratio 3.42 in males and 4.29 in female; proximal margins of pedipalp fingers of female straight (Figs. 61, 231), of male undulate so as to leave a gap with fingers closed (Figs. 59, 233); dentate margin of movable finger armed with 7 rows of granules, and a short apical row of 3–4 denticles (Fig. 7); most proximal granule row with one external accessory granule. Pectines with 17–19 teeth in both sexes. Hemispermatophore basal lobe a weak, oblique carina (Figs. 28, 36). Metasoma narrow, metasoma V length/width ratio is 2.40–2.46 in males and 2.56–2.58 in females (Figs. 76–77); metasoma I with 10 carinae, II–IV with 8 carinae. Telson setose, bearing numerous long macrosetae and short, pointed subaculear tubercle; vesicle smooth, elongate, ellipsoidal, slightly bulbous, telson length/depth ratio 2.27–2.37 in both sexes; aculeus slender, curved, shorter than vesicle. NOTE. In his original description, Borelli (1902: 3) assumed that the holotype was a male, and this was accepted by most subsequent authors. Only Lowe (2000: 190–191) questioned this assumption, observing that the holotype exhibited some characters more consistent with females of other species of Babycurus sensu lato, and noted that “Study of additional material is needed to clarify variation and sexual dimorphism in B. zambonellii ”. Recently, the first author (F.K.) was able to finally settle this question by collecting additional material representing both sexes of B. zambonellii. The new specimens clearly demonstrated that the holotype is indeed female, not male. B. zambonellii is an Eritrean endemic and the female which Sissom (1994) cited from Yemen represents a new species which we describe here as B. yemenensis sp. n. COMMENTS ON LOCALITY AND LIFE STRATEGY. The first author (F.K.) visited the locality 15EH (Figs. 224–225), a montane, forested habitat along a riverbed of an occasional river, on 3–4 November 2015. At this locality, the author recorded a maximum daytime temperature of 30.3 ºC, and minimum nighttime temperatures of 19.6 ºC. The recorded humidity was between 46% and 92%. In addition to B. zambonellii the first author also recorded Hottentotta minax (L. Koch, 1875) at this locality.Published as part of Kovařík, František, Lowe, Graeme & Šťáhlavský, František, 2018, Review of the genus Babycurus Karsch, 1886 (Arachnida, Scorpiones, Buthidae), with descriptions of Barbaracurus gen. n. and two new species from Oman and Yemen, pp. 1-41 in Euscorpius 267 on pages 33-36, DOI: 10.5281/zenodo.654415

Defining absolute environmental limits for the built environment
No full textThe question addressed is whether it is possible to define working limits on environmental impacts from the built environment in terms of global carrying capacity. The main focus is on energy-related impacts, since these are global and relatively well-understood. Four possible approaches to defining limits are explored: static equilibrium, asymptotic, integral of excess and planned future. The conclusions that emerge from this exploration are that global environmental constraints are very tight, but also that they are dynamically and strongly influenced by the trajectory of social and technological development over the coming century. Their use as the basis for practical, quantitative metrics of sustainability, therefore, involves a large measure of subjectivity. A fifth approach - the developmental approach - is identified, which instead of focusing on long-term external constraints to human activity, focuses instead on the internal, short- to medium-term dynamics of the built environment itself. It appears likely that the developmental approach, guided by qualitative conclusions from the analysis of global carrying capacity, is likely to be most fruitful
