Background: Iron deficiency and its related anemia, which is the world’s most widespread nutritional deficiency, can be one of the possible consequences of regular blood donation. This research was carried out to compare iron stores in regular blood donors and first-time blood donors in Tehran Regional Blood Transfusion Center. Materials and Methods: This study was carried out on 2,149 male bl...

The ability to store energy in the form of energy-dense TAG (triacylglycerol) and to mobilize these stores rapidly during times of low carbohydrate availability (fasting or famine) or during heightened metabolic demand (exercise or cold-stress) is a highly conserved process essential for survival. Today, in the presence of nutrient excess and sedentary lifestyles, the regulation of this pathway...

Online fashion sales present a challenging use case for personalized recommendation: Stores offer a huge variety of items in multiple sizes. Small stocks, high return rates, seasonality, and changing trends cause continuous turnover of articles for sale on all time scales. Customers tend to shop rarely, but often buy multiple items at once. We report on backtest experiments with sales data of 1...

The increasing gap between fast data processing speed and long access latency has become the bottleneck of memory intensive workloads. One way to reduce average load to use latency is to minimize cache misses. While cold misses can be eliminated via prefetching schemes, conflict misses cannot be avoided without an efficient replacement policy. Given future cache access sequences, Belady’s algor...

For experiments at the torque meter, flies are kept on standard fly medium at 25 degrees C and 60% humidity with a 12hr light/12hr dark regime. A standardized breeding regime assures proper larval density and age-matched cohorts. Cold-anesthetized flies are glued with head and thorax to a triangle-shaped hook the day before the experiment. Attached to the torque meter via a clamp, the fly's int...

White adipose tissue stores energy while brown adipose tissue contributes to body temperature maintenance through non-shivering thermogenesis. In addition, brite (brown-in-white) adipocytes resembling classical brown adipocytes within predominantly white adipose tissue can be found in response to cold adaptation or other stimuli. Even though our understanding of brite adipocyte formation has in...

Red delicious, Kala kulu and Golden delicious apples taken from different marketing locations and retail stores during minimum availability period were analyzed for nutritional and microbial quality. Twenty one samples were analyzed for proximate composition and 72 samples were examined for surface contaminants using standard techniques. The highest weights of large, medium and small sized appl...

Honey bee, Apis mellifera L. (Hymenoptera: Apidae), colonies infested by parasitic mites are more prone to suffer from a variety of stresses, including cold temperature. We evaluated the overwintering ability of candidate breeder lines of Russian honey bees, most of which are resistant to both Varroa destructor Anderson & Trueman and Acarapis woodi (Rennie), during 1999-2001. Our results indica...
