To measure alcian blue positive goblet cells, alcian blue staining was modified as previously reported [95]. WT and tp53 mutant larvae in various conditions were fixed in 4% PFA for overnight at 4 C and washed with 1XPBST at least 3 times. 0.05% Alcian blue solution with 1% HCl and 70% EtOH were incubated for 30 min. Then, specimens were cleared in acidic ethanol including 5% HCl, 70% EtOH for overnight at 4 C. Next, Specimens were dehydrated in an ethanol series (25, 50, 75, and 100% ethanol) and stored in 100% glycerol at 4 C before taking images. Alcian blue positive goblet cells in the mid-distal intestine corresponding to the region of 250 μm from the anus were counted using an SZX16 microscope and imaged with a TUCSEN Dhyana 400DC. To cover the total alcian blue positive goblet cells in the mid-distal intestines, at least 4 images having different z-axes were taken at the same location and stacked using a helicon focus 7 software (Heliconsoft).
It differs from its congeners through a complex of characters; high number of ;vertebrae (65) particularly the abdominal vertebrae (12), dorsal fin rays (60), anal fin rays (52), and caudal fin rays (8); comparatively low number of pectoral fin rays (18) which forms a deep notch with two widely spaced non-rudimentary rays; mouth horizontal; Jaw teeth simple and not uniserial; colour in life, blue-black anteriorly becoming pale posteriorly, blue pigment becoming dusky when preserved, peritoneum black.

Why is it that over 50 million individuals have downloaded this simple game? Many paid a few dollars or more for the advanced version. More compelling is the fact that not only do huge numbers download this game, they play it with such focus that the total number of hours consumed by Angry Birds players world-wide is roughly 200 million minutes a DAY, which translates into 1.2 billion hours a year. To compare, all person-hours spent creating and updating Wikipedia totals about 100 million hours over the entire life span of Wikipedia (Neiman Journalism Lab). I say these Angry Birds are clearly up to something worth looking into. Why is this seemly simple game so massively compelling? Creating truly engaging software experiences is far more complex than one might assume, even in the simplest of computer games. Here is some of the cognitive science behind why Angry Birds is a truly winning user experience.
Short-term memory management: It is a well-known fact of cognitive science that human short-term memory (SM), when compared to other attributes of our memory systems, is exceedingly limited. This fact has been the focus of thousands of studies over the last 50 years. Scientists have poked and prodded this aspect of human cognition to determine exactly how SM operates and what impacts SM effectiveness. As we go about our daily lives, short-term memory makes it possible for you to engage with all manner of technology and the environment in general. SM is a temporary memory that allows us to remember a very limited number of discrete items, behaviors, or patterns for a short period of time. SM makes it possible for you to operate without constant referral to long-term memory, a much more complex and time-consuming process. This is critical because SM is fast and easily configured, which allows one to adapt instantly to situations that might otherwise be fatal if one were required to access long-term memory. In computer-speak, human short-term memory is also highly volatile. This means it can be erased instantly, or more importantly, it can be overwritten by other information coming into the human perceptual system. Where things get interesting is the point where poor user interface design impacts the demand placed on SM. For example, a user interface design solution that requires the user to view information on one screen, store it in short-term memory, and then reenter that same information in a data field on another screen seems like a trivial task. Research shows that it is difficult to do accurately, especially if some other form of stimulus flows between the memorization of the data from the first screen and before the user enters the data in the second. This disruptive data flow can be in almost any form, but as a general rule, anything that is engaging, such as conversation, noise, motion, or worst of all, a combination of all three, is likely to totally erase SM. When you encounter this type of data flow before you complete transfer of data using short-term memory, chances are very good that when you go back to retrieve important information from short-term memory, it is gone! 2ff7e9595c
