Fasting-induced increases in food hoarding are dependent on the foraging effort level
No full textTwo strategies that have evolved to help animals meet energy demands are increases in body fat and in hoarded food. Reliance on each varies, but both are characterized by energy stored in excess of current demands for future use. Fasted Siberian hamsters decrease their lipid stores and, upon refeeding, food hoarding rather than food intake increases. Here, we tested the effect of foraging-effort level on fasting-induced increases in food hoarding and whether decreases in total body fat or individual fat pad masses were associated with the hoarding increases. This was accomplished by housing female Siberian hamsters in a foraging/hoarding system where they earned food pellets upon completion of a programmed number of wheel revolutions (10, 75 or 200 per 75-mg pellet), or had no foraging requirement (free food and an active or blocked running wheel). After baseline, half the hamsters in each group were food deprived for 32 h and then refed (control hamsters were killed after the fast without refeeding). Fasted –refed hamsters increased foraging and food hoarding, especially at the lowest foraging effort, but not food intake, with few exceptions. These responses became progressively smaller as foraging effort increased. Fasting induced similar losses in carcass lipid across foraging efforts, but the lipid loss was not uniform across the fat pads and was not clearly related to hoard size. Collectively, the fasting-induced, increased food hoarding may be triggered by an overall change in energy metabolism rather than by a general or fat-pad-specific decrease in lipid stores.

Baldy #1: Heart-Stopper
No full textHello, my name is Zita. But here, at the La Gaufre hospital, everyone calls me "Baldy" I have a type of leukemia that seems to be especially fond of my body. Because of all the treatments I have undergone, I now only have a few tufts of hair left on my head. So I prefer to shave my head bald. Hence my nickname
A Search for Cosmic Ray Bursts at 0.1 PeV with a Small Air Shower Array
No full textThe Cosmic Ray Extremely Distributed Observatory (CREDO) pursues a global research strategy dedicated to the search for correlated cosmic rays, so-called Cosmic Ray Ensembles (CRE). Its general approach to CRE detection does not involve any a priori considerations, and its search strategy encompasses both spatial and temporal correlations, on different scales. Here we search for time clustering of the cosmic ray events collected with a small sea-level extensive air shower array at the University of Adelaide. The array consists of seven one-square-metre scintillators enclosing an area of 10 m × 19 m. It has a threshold energy ~0.1 PeV, and records cosmic ray showers at a rate of ~6 mHz. We have examined event arrival times over a period of over 2.5 years in two equipment configurations (without and with GPS timing), recording ~300 k events and ~100 k events. We determined the event time spacing distributions between individual events and the distributions of time periods which contained specific numbers of multiple events. We find that the overall time distributions are as expected for random events. The distribution which was chosen a priori for particular study was for time periods covering five events (four spacings). Overall, these distributions fit closely with expectation, but there are two outliers of short burst periods in data for each configuration. One of these outliers contains eight events within 48 s. The physical characteristics of the array will be discussed together with the analysis procedure, including a comparison between the observed time distributions and expectation based on randomly arriving events
A New Insight on the Radioprotective Potential of Epsilon-Aminocaproic Acid
No full textThe aim of the study was to scrutinize the ability of epsilon-aminocaproic acid (EACA) to prevent radiation-induced damage to human cells. Materials and Methods: Human peripheral blood mononuclear cells (PBMCs) were exposed to ionizing radiation at three low doses (22.62 mGy, 45.27 mGy, and 67.88 mGy) in the presence of EACA at the concentration of 50 ng/mL. Results: EACA was able to prevent cell death induced by low-dose X-ray radiation and suppress the formation of reactive oxygen species (ROS). EACA also demonstrated a capacity to protect DNA from radiation-induced damage. The data indicated that EACA is capable of suppression of radiation-induced apoptosis. Comparative tests of antioxidative activity of EACA and a range of free radical scavengers showed an ability of EACA to effectively inhibit the generation of ROS. Conclusions: This study showed that the pretreatment of PBMCs with EACA is able to protect the cells from radiation-elicited damage, including free radicals’ formation, DNA damage, and apoptosis

The Smurfs Anthology #5
No full textSmurf vs. Smurf and Smurf Soup get the Anthology treatment! While Papa Smurf works in his laboratory, two Smurfs begin arguing about the proper use of the word "smurf." Smurfs that live in the northern part of the village use it as a verb (as in "bottle smurfer"), while the southerners use it as a noun (as in "smurf opener"). Without Papa Smurf around to calm things down, the argument quickly escalates until the northern and southern smurfs divide themselves along the village lines! Plus, another never-before-seen Johan & Peewit comic, featuring the Smurfs
