the reproductive biology of the iranian cichlid, iranocichla hormuzensis coad, 1988, was investigated for 13 consecutive months in lower mehran river, from august 2008 through august 2009. four hundred and eighty six individuals (252 males and 234 females) were captured using a seine net (5 mm mesh size). the observed sex ratio was 1m: 0.93f (χ², df = 1, p = 0.414). mean ± sd of total length (t...
NOTCH signaling is deregulated in the majority of T-cell acute lymphoblastic leukemias (T-ALL) as a result of activating mutations in NOTCH1. Gamma secretase inhibitors (GSI) block proteolytic activation of NOTCH receptors and may provide a targeted therapy for T-ALL. We have investigated the mechanisms of GSI sensitivity across a panel of T-ALL cell lines, yielding an approach for patient stra...
OBJECTIVE The recently developed global synchronization index (GSI) quantifies synchronization between neuronal signals at multiple sites. This study explored the clinical significance of the GSI in Alzheimer's disease (AD) patients. METHODS Electroencephalograms were recorded from 25 AD patients and 22 age-matched healthy normal controls (NC). GSI values were computed both across the entire ...
Some reproduction aspects of the "doctor fish", Cyprinion macrostomum, were examined for the first time from the Tigris River drainage. A total of 316 specimens were caught from Gamasiab River in western Iran, at monthly intervals throughout the year from January to December 2013. Age, sex ratio, fecundity, oocytes diameter, gonado‑somatic (GSI), modified gonado‑somatic (MGSI) and Dobriyal (DI)...
Geospatial Information (GSI) services are a new kind of technological platform that combine accurate mapping services with real-time user location and context data. GSI can power everything from navigation to social and political engagement. Although many GSI services are already in use, little attention has been paid to the implications of the technology and the privacy concerns that it raises...
BACKGROUND In Sardinia, as in other regions of the Mediterranean Sea, sustainable fisheries of the sea urchin Paracentrotus lividus have become a necessity. At harvesting sites, the systematic removal of large individuals (diameter ≥ 50 mm) seriously compromises the biological and ecological functions of sea urchin populations. Specifically, in this study, we compared the reproductive potential...
The giant river prawn (Macrobrachium rosenbergii) is one of the most farmed freshwater crustaceans in the world. Its global production has been stalling in the past decade due to the inconsistent quality of broodstock and hatchery-produced seeds. A better understanding of the role of nutrition in maturation diets will help overcome some of the production challenges. Arachidonic acid (20:4 n-6, ...
Small pelagic fish (SPF) in the western Mediterranean Sea are key elements of marine food web and important terms biomass fisheries catches. Significant declines biomass, landings, changes age/size structure sardine Sardina pilchardus anchovy Engraulis encrasicolus have been observed recent decades, particularly northern area Sea. To understand different patterns SPF populations, we analyzed li...
