Seasonal changes of the thyroid gland structure and hormones secretion was examined in yellowfin seabream (Acanthopagrus latus) in the northwest of Persian Gulf (Musa creek). Thyroid gland composed of follicles scattered around the ventral aorta, near the gills. Follicular cells varied according to secretion of the gland during warm and cold seasons. Thyroid hormones (Triidothyronine [T3] and ...

Historical surface air temperature (SAT) records from 59 Arctic stations north of 64°N show monthly anomalies of several degrees and large spatial teleconnectivity yet major seasonal and regional differences, based on time/longitude plots of SAT anomalies and Principal Component Analysis (PCA). Using monthly station data rather than gridded fields for this analysis highlights the importance of ...

Housing temperature effects on growth, feed utilization and feed digestion of 12, 7-mo-old Standardbred colts were evaluated for 22 wk beginning in late November. Colts were assigned to one of two treatments: housed in a barn heated at 10 degrees C (warm) or housed in a barn with no external heat supply (cold). All horses were allowed outdoors for 4 h daily. Mean temperatures of the warm and co...

As part of the HAUSGARTEN long-term observatory, sediment trap deployments were carried out before, during, and after the anomalously warm Atlantic Water inflow observed from 2005 to 2007 in the eastern Fram Strait. Downward export of particulate organic carbon (POC), zooplankton fecal pellet carbon (FPC), and biogenic particulate silica (bPSi) were measured from August 2002 to June 2003 and fr...

the new line (kauz/pastor//bav92/rayon cmss00m02400s-030m-030wgy-030m-9m-0y) (gaboos cultivar) was evaluated at gachsaran and gonbad agricultural research stations in the first time in 2006-2007. due to optimum earliness, plant height, kernel weight and successful performance of grain yield in observation nursery, preliminary and advanced yield trials (2007-2009), this genotype along to 16 prom...

The aim of the present study was to determine the efficacy of ivermectin against Cyathostominae infections and to describe the drug's pharmacokinetic parameters during two seasonal deworming treatments in horses. The study was performed on warm-blooded mares aged 3-12 years weighing 450-550 kg. A single bolus of an oral paste formulation of ivermectin was administered at a dose of 0.2 mg/kg BW ...
