It is shown that in loach embryos the incorporation of precursors into protein takes place in the blastoderm cells only. The change of the rate of incorporation of labelled amino acids into protein of the blastoderm separated from the yolk at successive developmental stages reflects the changes in the level of protein synthesis in intact embryos of the same developmental stages. Typical periodi...

Two distinct cDNAs encoding aquaporins (mmAQPs 1a and 3a) were isolated and characterized from mud loach Misgurnus mizolepis. The identified mud loach AQP cDNAs encode for polypeptides of 260 and 302 amino acids. Topology predictions confirmed six putative membrane-spanning domains connected by five loops and the Nand C-terminal domains being cytoplasmic. The mud loach AQPs 1a and 3a showed bro...

The concept of strong spined product of semigroups is introduced. We first show that a semigroup S is a rpp-semigroup with left central idempotents if and only if S is a strong semilattice of left cancellative right stripes. Then, we show that such kind of semigroups can be described by the strong spined product of a C-rpp-semigroup and a right normal band. In particular, we show that a semigro...

This study provides new data on chromosomal characteristics and DNA barcoding of three endemic loaches of Iran: spiny southern loach Cobitis linea (Heckel, 1847), Persian stream loach Oxynoemacheilus persa (Heckel, 1848) and Tongiorgi stream loach Oxynoemacheilus tongiorgii (Nalbant & Bianco, 1998). The chromosomes of these fishes were investigated by examining metaphase chromosome spreads obta...
