- Description:
- Adjuvant therapy and radiotherapy improves the survival of patients with metastatic and locally advanced gastric cancer (GC). However, the resistance to radiotherapy limits its clinical usage. Rhotekin 2 (RTKN2) functions as an oncogene and confers resistance to ultraviolet B-radiation and apoptosis- inducing agents. Here, the role of RTKN2 in radiosensitivity of GC cell lines was investigated. RTKN2 was found to be elevated in GC tissues and cells. A series of functional assays revealed that overexpression of RTKN2 induced GC cell proliferation, promoted GC cell migration and invasion, while inhibiting GC cell apoptosis. However, silence of RTKN2 promoted GC cell apoptosis, while repressing GC cell proliferation, invasion and migration. GC cells were exposed to irradiation, and data from cell survival and apoptotic assays showed that knock-down of RTKN2 enhanced radiosensitivity of GC through up-regulation of apoptosis and down-regulation of proliferation in irradiation-exposed GC cells. Moreover, the protein expression of β-catenin and c-Myc in GC cells was enhanced by RTKN2 over-expression, but reduced by RTKN2 silence. Interference of RTKN2 down-regulated nuclear β-catenin expression, while up-regulating cytoplasmic β-catenin in GC. In conclusion, RTKN2 contributed to cell growth and radioresistance in GC through activation of Wnt/β-catenin signalling.

- Description:
- Ruavermis mikebargeri gen. et sp. n. infects the yellow-headed temple turtles Heosemys annandalii (Boulenger et Robinson) in the Mekong River Basin. It resembles Platt Roberts et Bullard, 2018 and Coeuritrema Mehra, 1933 by having the anterior to posterior anatomical sequence of a ventral sucker, external seminal vesicle, cirrus sac, anterior testis, ovary, transverse vitelline duct, and posterior testis. These genera are further similar by having the combination of an elongate/ovoid aspinous body, a ventral sucker at the level of the body constriction, an oesophagus that terminates in the anterior 1/5 of the body and that is ventral to the anterior nerve commissure, intestinal caeca that bifurcate in the anterior 1/3 of the body (not immediately anterior to the ventral sucker), a sinistral caecum that bends toward the midline at level of the cirrus and common genital pore, an external seminal vesicle that abuts the anterodextral margin of the cirrus sac, an oviduct that emerges from the dextral margin of the ovary, and an oviducal seminal receptacle that comprises the middle portion of the oviduct. These genera lack lateral oesophageal diverticulae and a median oesophageal diverticulum. The new genus is unique by having a papillate ventral body surface, an external seminal vesicle lateral to the cirrus sac, vasa efferentia that are ventral to the gonads, an oviduct that is convoluted, a Laurer's canal pore that is preovarian, a Laurer's canal that extends anterolaterad, and an excretory vesicle that is Y-shaped. The 28S rDNA phylogenetic analysis recovered the new species sister to Coeuritrema platti Roberts et Bullard, 2016, with that clade sister to Hapalorhynchus spp. and Platt spp. The new turtle blood fluke is the fourth from Vietnam, second from a Vietnam geomydid, and first from Heosemys Stejneger as well as the first endohelminth from the yellow-headed temple turtle., Haley R.

33335. Rubidium marking of Aphidius rhopalosiphi (Hymenoptera: Braconidae) on Sitobion avenae (Hemiptera: Aphididae) reared on a diet supplemented with RbCl

- Description:
- Markers are essential to study movements of insects in their natural habitat. Among the available techniques, trace elements may be applied to insects as small as parasitoids. Rubidium is the most common element used for marking insects. In this study, we propose a simple marking technique for Aphidius rhopalosiphi De Stefani Perez with Rb, when reared on the grain aphid Sitobion avenae Fabricius (Hemiptera: Aphididae) marked on a RbCl incorporated diet. Our results show that the rubidium in an artificial diet is transferred to the aphid and eventually to the parasitoid. The content in rubidium marking did not differ between genders. The aphids stung by a marked parasitoid could not be distinguished from unmarked aphids on the basis of their rubidium content. There were no effects of rubidium on size, fecundity, longevity and sex ratio of the parasitoid, but the marked individuals emerged significantly later than the unmarked. We did not detect differences concerning host acceptance by marked and unmarked parasitoids. This technique may be applicable to other aphidophagous insects after some preliminary evaluations.

- Type:
- article and TEXT
- Subject:
- Austria, batology, Czech Republic, ecology, phytosociology, Rosaceae, Rubus, sect. Corylifolii, and taxonomy
- Language:
- English
- Description:
- A new species of bramble, Rubus kletensis, of the section Corylifolii Lindley, series Sepincola (Focke) E. H. L. Krause occurring in South Bohemia and Upper Austria is described. The distance between the most distant localities exceeds almost 150 km. This distinct and relatively easily recognizable species grows in rather moist, eutrophic, synanthropic and sunny biotopes, and occurs most frequently in the vegetation of the class Galio-Urticetea, less frequently in that of the alliances Trifolion medii, Pruno-Rubion radulae, Sambuco-Salicion capreae, Berberidion and exceptionally in forest plantations and growths of pioneer saplings. A distribution map for this species and a list of all known localities are included, as well as a drawing of the species.

- Language:

- Description:
- Rubus silvae-bohemicae is described as a new regional apomictic species belonging to the subgen. Rubus sect. Rubus ser. Micantes Sudre. It is a nemophilous bramble occurring in south-western and southern Bohemia (Czech Republic) and adjacent parts of Bavaria (Germany). It differs from the somewhat similar species, R. indusiatus Focke, by having no stellate hairs on the undersides of the leaves and a lower number of shorter stalked glands and lower number of prickles on first-year stems. An illustration of the new species (including a photograph of the type specimen), a list of localities and a distribution map are presented.

33340. Rubus silvae-norticae, a new species from Bohemia, Austria and Bavaria and the significance of brambles for regional migrations
- Creator:

- Type:
- article and TEXT
- Subject:
- Austria, batology, Czech Republic, ecology, Germany, migration, phytogeography, Rosaceae, Rubus, and taxonomy
- Language:
- English
- Description:
- A new bramble species, Rubus silvae-norticae, section Rubus, subsection Hiemales E. H. L. Krause in Prahl, series Micantes Sudre, which occurs in S Bohemia, Upper Austria and Lower Bavaria, is described. It is recorded at 130 localities. The distance between the most remote localities is ca 100 km. The species grows most frequently in forest habitats (as a distinctly nemophilous ecoelement) such as ditches and edges of forest roads, plantations, forest margins and clearings. It mainly grows in mesic, acid and mineral-poor soils. Like, for example, R. clusii or R. ser. Glandulosi and unlike other relatively thermophilous Rubus species, it is able to grow and propagate itself at rather high altitudes, up to the mountain vegetation belt. The diagnostic characters that separate R. silvae-norticae from its most similar and sympatrically occurring species, R. clusii and R. muhelicus, are provided. In Austria R. silvae-norticae and some other brambles were mistakenly considered as R. helveticus, a bramble (probably a single biotype) described from Switzerland in 1870. The lectotype of Rubus helveticus is designated here and a photograph of the specimen presented. Also included is a distribution map of R. silvae-norticae, a list of revised herbarium specimens, a photograph of the type specimen and a pen drawing of the species. The significance of regional brambles for plant migrations and phytogeography is shown, based on the distribution of selected regional Rubus species occurring in the Czech and Austrian border area, which is a known mountain barrier to migration. The distribution patterns of the brambles support a theory about the routes of plant migration and the florogenetic connection between Austria and the Czech Republic. Rubus silvae-norticae, R. muhelicus and R. vestitus f. albiflorus are regarded as Danubian migrants (distributed from Upper Austria to S Bohemia), whereas R. gothicus s. l. (“south Moravian type”) and R. austromoravicus are considered to be Dyje-Kamp migrants (distributed from Moravia and Lower Austria to S Bohemia) within the Bohemian flora. Rubus kletensis is supposed to be a Vltava migrant within the Austrian flora (distributed from S Bohemia to Upper Austria).
