F-spondin, an extracellular matrix protein, is an important player in embryonic morphogenesis and CNS development, but its presence and role later in life remains largely unknown. We generated a transgenic zebrafish in which GFP is expressed under the control of the F-spondin (spon1b) promoter, and used it in combination with complementary techniques to undertake a detailed characterization of ...

The purpose of this paper is to study very early retirement as an indicator for poor health, with focus on a comparison between the two language groups in Finland. Extensive longitudinal data are analysed with the help of random effects probit models. As expected from previous studies of mortality differences, the rate of retirement is lower among Swedish-speakers than among Finnish-speakers, a...

The vertebrate peripheral nervous system (PNS) originates from neural crest and placodes. While its developmental origin is the object of intense studies, little is known concerning its evolutionary history. To address this question, we analyzed the formation of the larval tail PNS in the ascidian Ciona intestinalis. The tail PNS of Ciona is made of sensory neurons located within the epidermis ...

A new labrid fish Terelabrus dewapyle sp. nov. is described as the second species of the genus, on the basis of five specimens collected from southern Japan, Papua New Guinea, and Fiji in depths of 72-92 m. The sole paratype of T. rubrovittatus Randall & Fourmanoir 1998 is herein identified as T. dewapyle and designated as a paratype of the latter. The new species can be distinguished from T. r...

This study numerically investigates the effects of the number of bottom openings and the fin spacing on both the natural convection heat transfer and airflow field of the handheld projector with various orientations. The horizontally-oriented 120 mm × 53 mm × 19 mm handheld projector, which had 11 bottom openings and was installed with either 7 plate fins or 13 rows of square pin, was considere...

Rajiform locomotion in fishes is dominated by distinctive undulations of expanded pectoral fins. Unlike other fishes, which typically interact with the fluid environment via multiple fins, undulating rays modulate a single control surface, the pectoral disc, to perform pelagic locomotion, maneuvering and other behaviors. Complex deformations of the broad, flexible pectoral fins occur as the und...

The Finnish Rheumatoid Arthritis Combination Therapy Trial (FIN-RACo) started in 1993, in an era of disappointing results in the treatment of rheumatoid arthritis (RA). The FIN-RACo was the first trial aiming at remission and comparing two different treatment strategies: initially triple therapy with compulsory prednisolone (FIN-RACo strategy), or monotherapy with optional prednisolone (SINGLE ...

Accurate prediction of the performance ofcooling coils is fundamental to the design of efficient ventilation and air-conditioning systems. The actual heat transfer that takes place can be considered as the performance evaluating criteria for any system and this can be expressed in terms of fin efficiency. Fin efficiency is a function of ambient conditions and fin geometry parameters. Obtaining ...

The results obtained using morphometric variables which describe fin ray regeneration patterns are reported for individual fin ray amputations in the goldfish (Carassius auratus) and zebrafish (Brachydanio rerio). Classical and updated experiments are compared to verify previous morphogenetic models of cell tractions (Oster et al. 1983) or epidermis-mesenchyme induction (Saunders et al. 1959) a...

Pseudophoxinus burduricus sp. n. is described from drainages of Salda and Burdur lakes, southwestern Turkey. It is distinguished from other Anatolian Pseudophoxinus by a combination of characters: lateral line incomplete, with 21-39 (commonly 26-37) perforated scales and 47-57+1-2 scales in lateral series; 10½-12½ scale rows between lateral line and dorsal fin origin, 3-4(5) scale rows between ...
