Megarthrus budai Liu and Cuccodoro sp. nov. from Sichuan province in China is described. It is the first record of the genus from Mount Emei, a temperate biodiversity-rich mountain to which this new species seems to be endemic. Megarthrus basicornis Fauvel, 1904, known so far only from India and Nepal, is reported from China for the first time.These two species have many features found mainly in members of the predominantly Holarctic and African M. depressus supergroup of species.Microcambeva bendego, a small psammophilous catfish species, is described from the rio Guapi-Macacu basin at Guanabara Bay in Rio de Janeiro State, an Atlantic Forest remnant. This coastal drainage has been explored by several naturalists and fish researchers since the 19th century. It is a drainage with remarkably high endemism and species richness, and some recently-described and threatened species. The new species is distinguished from all congeners by two distinctive characters long finger-like projections in the branchial isthmus and a large opercular patch of odontodes with 19 odontodes. Due to the paucity of specimens (n=3) osteological features of the new species were accessed by CT-Scan images of the holotype. Microcambeva bendego shares putative synapomorphies with two congeners, M. ribeirae and M. filamentosa, such as the fusion of supraorbital pore s6, the absence of ossification in the anterior autopalatine cartilage, the presence of an elongated and wide posterior process of the autopalatine, and a concavity on the dorsal process of the opercle. Those characters suggest that M. bendego is more closely related to those two species from the rio Ribeira de Iguape basin than to other congeners. The biogeography and conservation status of M. bendego are also discussed.A new calopterygid species Caliphaea hermannkunzi sp. nov. (holotype ♂ China, Yunnan Province, Lufeng County, Chuxiong City, Gaofeng village, 10 June 2019) is described and illustrated for both sexes and compared with its named congeners, from which it differs in the colour pattern of synthorax and the structure of the male anal appendages.Schistura falamensis, a new species of nemacheilid loach, is described from the main channel of the Manipur River in the Irrawaddy River basin, Chin State, western Myanmar. It differs from other congeners of the genus Schistura by a combination of the following characters 5-8 vertical bars on body; indistinct bars in front of dorsal-fin origin; bars on posterior part of body regular, twice as wide as interspace; black caudal basal bar dissociated, short, not reaching ventral extremity; males with suborbital flap; lateral line complete; and processus dentiformis weak. Schistura altuscauda is a new species described from the Htin stream, Mindat Town, Chin State, Myanmar. It can be distinguished from other congeners by a combination of the following characters high caudal peduncle (14.0-20.3% SL), strong processus dentiformis on upper jaw; 7-19 bars on flank of body, bars in front of dorsal fin obviously thinner than those behind, sometimes fused in front of dorsal fin; lateral line complete; males with prominent suborbital flap; and pelvic lobe present.Advikus gen. nov. and three new species, Advikus siddappaji sp. nov. (type species, India Karnataka), A. andamanicus sp. nov. (India Andaman Nicobar Islands) and A. radhamaniae sp. nov. (India Karnataka) are described and illustrated. A key to the known genera of the tribe Scaphoideini from the Indian subcontinent and also the three new species are provided. A lectotype for Gunghuyana cingalensis Distant is designated and the female type is redescribed and illustrated.Natural history museum collections can be a helpful tool in documenting changes in biodiversity throughout decades or even centuries. This article uncovers information on the content of three different museum collections, collected over 100 years. selleck chemicals llc It deepens the knowledge on the distribution of pyraloid moth species occurring predominantly in the Continental parts of Croatia, but also in other areas of this country. The article presents the first published listing of pyraloid moth species held in three museum collections of the Croatian Natural History Museum in Zagreb. The list contains 148 taxa in total, 61 from the Igalffy collection, 96 from the Koča collection, and 96 from the Kučinić collection. Altogether, 96 species from the family Crambidae and 52 species from the family Pyralidae are listed.Species from almost all classes of ciliates are prone to be found inhabiting bromeliads in the Neotropics, from Mexico to Brazil, and the Antilles. Studies of ciliates recorded from bromeliads have been carried out from few bromeliad species, mainly in tropical forest. We compiled all available data of free living and sessile ciliates from bromeliads, including their geographic distribution and bromeliad identity. We provide a list of 170 ciliate species that have been recorded in 52 epiphytic and terrestrial bromeliad species, distributed in ten Neotropical countries . Most of the species belong to the Classes Oligohymenophorea, Colpodea and Spirotrichea. The largest number of ciliate species has been recorded in Brazil and Mexico. Bromeliothrix metopoides and Glaucomides bromelicola were the two species with the widest geographical distribution, 19 species have been recorded only in Mexico, 11 in the Antillean islands, and 89 only in Southamerica. Free living species prevailed over sessile species, and both represent 2% of the total ciliate species number. Sixteen ciliate species have been recorded only inhabiting in bromeliads. Although bromeliads show a high endemicity, their specificity is low in relation to ciliates.

The role of postoperative radiation therapy (PORT) for thymoma is under debate, especially in patients aged ≥60 years with an advanced stage (Masaoka stages III and IV). We aimed to evaluate the efficacy of PORT for thymoma in a population-based registry.

A retrospective analysis of the Surveillance, Epidemiology, and End Results (SEER) database was conducted to compare the outcomes of thymoma patients with or without PORT. The primary outcomes were overall survival (OS) and cancer-specific survival (CSS). Conditional inference tree analyses were performed for risk classification according to the study variables. Cox regression was performed to evaluate the prognostic effect of PORT in the specific subgroups.

A total of 2,236 patients were included. The conditional inference tree analysis identified that an age ≥60, a Masaoka stage ≥3, and the year of diagnosis were important factors when classifying patients into prognostic subgroups. PORT was found to be a protective predictor of OS in patients aged ≥60 years, those with a Masaoka stage III-IV, and those diagnosed after 2005.
