Tbx5 plays a pivotal role in vertebrate forelimb initiation, and loss-offunction experiments result in deformed or absent forelimbs in all taxa studied to date. Combining single-cell fate mapping and threedimensional cell tracking in the zebrafish, we describe a Tbx5adependent cell convergence pattern that is both asymmetric and topological within the fin-field lateral plate mesoderm during ear...

the distribution of yellowfin seabream populations in estuaries and inland rivers in coastal area of the persian gulf and strait of hormuz is presented. based on morphological and mersitic characteristics and also color pattern, these populations are assigned to the recently described sparid fish, acanthopagrus arabicus iwatsuki, 2013 which is distinguished by pelvic and anal fins vivid or stro...

In the article concepts and facts necessary to continue formalization of theory of continuous lattices according to [11] are introduced. and [4] provide the notation and terminology for this paper. 1. PRELIMINARIES The following two propositions are true: (1) For all sets X, A, B such that A ∈ Fin X and B ⊆ A holds B ∈ Fin X. (2) For every set X and for every family F of subsets of X such that ...

Sinocyclocheilus brevifinus sp. nov. is described from a subterranean river at Maohedong Village, Guangxi Zhuang Autonomous Region, Southern China. The new species can be distinguished from all congeners in having functional eyes, last simple dorsal fin ray soft and without serrations along posterior margin, eye diameter small (3.4-5.0 %SL), tip of depressed dorsal fin not reaching vertical at ...

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 ...
