Action potentials (APs) and impulse responses in the soma and axon of the rapidly and slowly adapting (SA) abdominal stretch receptor neurons of the crayfish (Astacus leptodactylus) were recorded with single microelectrode current-clamp technique. Impulse frequency response to constant current injection was almost constant in the SA neuron while the response decayed completely in the rapidly ad...
Cadmium injections induced only a single form of metallothionein (MT) in the midgut gland of Potamon potamios, whereas the same treatment induced two isoforms in Astacus astacus. The only difference between the two latter isoforms was that one had an extra N-terminal methionine residue. MT from P. potamios showed structural differences from other decapod crustacean MTs. It contained a Gly-Thr m...
این تحقیق از شهریور ماه سال 1389 تا مرداد ماه سال 1390 به مدت یکسال به منظور بررسی رابطه طول و وزن خرچنگ دراز Astacus leptodactylus رها سازی شده در سد شیان استان کرمانشاه انجام گرفت . نمونه برداری به صورت ماهانه صورت پذیرفت و در مجموع 182 عدد خرچنگ شامل 126 عدد نر و 56 عدد ماده صید گردید. نسبت جنسی نربه ماده درخرچنگ های صید شده 25/2به1(نر ، ماده= 69/0، 31/0) محاسبه گردید. میانگین طول کل خرچ...
White spot syndrome virus, type species of the genus Whispovirus in the family Nimaviridae, is a large, double-stranded DNA (dsDNA) virus that infects crustaceans. The genome of the completely sequenced isolate WSSV-TH encodes 184 putative open reading frames (ORFs), the functions of which are largely unknown. To study the transcription of these ORFs, a DNA microarray was constructed, containin...
The usage of the name Rana ocellata Linnaeus, 1758, is plagued by misidentifications and misinterpretations. After an exhaustive bibliographic review, we conclude that the Linnaeus 1758 name refers to Osteopilus brunneus (Gosse, 1851) from Jamaica, while the taxon currently known as Leptodactylus ocellatus corresponds to Rana latrans Steffen, 1815. Herein, we designate and provide descriptions ...
