Molecular cloning and sequence of gilthead sea bream (Sparus aurata) alpha-skeletal actin: tissue and developmental expression
(2001)In the present study, the Sparus aurata alpha -skeletal actin was cloned from a mixed larvae complementary DNA library. The clone isolated was 1523 bp long with an open reading frame of 1134 bp coding for a 377-amino acid ... -
Molecular cloning of four glutathione peroxidase (GPx) homologs and expression analysis during stress exposure of the marine teleost Sparus aurata
(2014)Glutathione peroxidase (GPx; EC 1.11.1.9) is an important family of enzymes that protects organisms from oxidative damage. Four full-length GPx cDNAs were cloned and characterized by rapid amplification of cDNA ends ... -
Morphological study of muscular tissue collagen of wild and reared Cornu aspersum (Muller, 1774)
(2013)Muscular tissue collagen fibrils' diameter and period of reared and wild snails (Cornu aspersum) were measured in order to investigate the role of nutrition on the collagen. Wild adult individuals were collected from Crete ... -
Multiple biomarkers of pollution effects in caged mussels on the Greek coastline
(2010)A suite of biomarkers was measured in caged mussels at areas impacted by different anthropogenic activities along the Greek coastline to assess biological effects of environmental pollution. Mussels were caged at coastal ... -
A new species of Halichondriidae, Topsentia vaceleti n. sp (Halichondrida, Demospongiae, Porifera), collected from coralligenous bottoms of the Aegean Sea
(2012)A new species, Topsentia vaceleti n. sp., was collected from 70m depth, on a coralligenous bed of the Aegean Sea by trawl (sponge fishing gear "gagava"). The specimen is spherical, 8 cm in diameter, with deep surface ... -
Occurrence of non-cerebral coenurosis in sheep
(2013)This study reports seven rare cases of non-cerebral coenurosis in sheep. The sheep were slaughtered in abattoirs of Abu Dhabi (United Arab Emirates) but originated from India, Iran, Oman and Sudan. The prevalence of infection ... -
Patterns of gastric evacuation, digesta characteristics and pH changes along the gastrointestinal tract of gilthead sea bream (Sparus aurata L.) and European sea bass (Dicentrarchus labrax L.)
(2011)A comparative study of gastric evacuation rates (GERs) and digesta content, moisture and pH values along the gastrointestinal tract was performed between gilthead sea bream and European sea bass. In order to distinguish ... -
Pharmacokinetics and clinical assessment of amoxicillin for the control of necrotic enteritis in broiler-breeders under field conditions
(2015)Necrotic enteritis (NE) is an acute clostridium infection characterised by sudden onset, high mortality and severe necrosis of intestinal mucosa. The present study was conducted to clinically assess the efficacy of amoxicillin ... -
Physiological and biological patterns of a highland and a coastal population of the European cherry fruit fly during diapause
(2011)Adult emergence of univoltine temperate insect species and its synchronization with specific host phenological stages is mainly regulated by obligatory pupal diapause. Although a few studies have investigated the factors ... -
Polygyny in the olive fly-effects on male and female fitness
(2015)Polygynous males must balance their limited ejaculate resources between current copulations, with putative future ones. Working on olive flies (Bactrocera oleae), our objectives were to determine (a) how males budget sperm ... -
Prolonged pupal dormancy is associated with significant fitness cost for adults of Rhagoletis cerasi (Diptera: Tephritidae)
(2012)In temperate areas, dormancy (diapause and/or quiescence) enables herbivorous insect species to persist and thrive by synchronizing growth and reproduction with the seasonal phenology of their host plants. Within-population ... -
Proteins from fish eggs that protect DNA from acid precipitation and inhibit DNA synthesis
(2001)We partially characterized proteins that inhibit DNA acid precipitation from various fish eggs (Sparus aurata, Dicentrarchus labrax, Mugil cephalus and Zeus faber). The active proteins were purified by acetone fractionation. ... -
Relationship between morphologic and genetic variation in red mullet (Mullus barbatus) populations from Greek Seas
(1998)Data derived from morphometric, allozymes and RAPD analyses were compared, in order to investigate the possible relationships between morphologic and genetic variation observed in seven Mediterranean red muller (Mullus ... -
Reproductive biology of the marbled goby, Pomatoschistus marmoratus (Pisces, Gobiidae), in a northern Aegean estuarine system (Greece)
(2009)The reproductive biology of the marbled goby, Pomatoschistus marmoratus (Risso, 1810), was studied in the Strymon River estuarine system (northern Greece) between September 1997 and August 1999. Samplings were conducted ... -
The reproductive cycle of Norway lobster
(2009)The reproductive biology of female Norway lobster Nephrops norvegicus was studied throughout an annual cycle from January to December 2007 in Pagasitikos Gulf, a large semi-enclosed Gulf in the central west Aegean Sea, in ... -
Reproductive cycle of the traditionally exploited sea cucumber Holothuria tubulosa (Holothuroidea: Aspidochirotida) in Pagasitikos Gulf, western Aegean Sea, Greece
(2014)The reproductive cycle of the traditionally exploited sea cucumber Holothuria tubulosa was investigated in the Pagasitikos Gulf (39 degrees 18'457 '' N, 23 degrees 05'869 '' E) from June 2007 to July 2008. The study examined ... -
