A method for "skinning" arterial smooth muscle is presented which yields isometric tension development typically 60-80% of maximum physiological tension in the presence of micromolar Ca++ and millimolar Mg-ATP, while retaining essentially the native protein content. Using the methods of "CA jump," the time-course of Ca++-activated tension development in the skinned artery can be made identical ...
Skin lightening among Eurasians is thought to have been a convergence occurring independently in Europe and East Asia as an adaptation to high latitude environments. Among Europeans, several genes responsible for such lightening have been found, but the information available for East Asians is much more limited. Here, a genome-wide comparison between dark-skinned Africans and Austro-Asiatic spe...
Fungiform papillae of the tongue are small projections involved in taste function that are typically located on the lateral aspects and tip of the tongue. They are called fungiform papillae because of their close resemblance to a fungus. In fair-skinned individuals, they are usually pink or red, but in dark-skinned individuals, they are frequently pigmented and are considered a variant of norma...
Recent studies have shown that differences in wage-determinant skills between blacks and whites are likely to emerge during a child’s infancy. These findings highlight the role of parental investment decisions and suggest that differences in labor income tend to persist across generations, either because minority parents are limited in their choices, or because they have relatively negative exp...
Generating plausible deformations of a character skin within the standard production pipeline is a challenge. This paper presents a volume preservation method dedicated to skinned characters. As usual, the character is defined by a skin mesh at some rest pose and an animation skeleton. At each animation step, skin deformations are first computed using standard SSD. Our method corrects the resul...
The Frank-Starling relationship of the heart has, as its molecular basis, an increase in the activation of myofibrils by calcium as the sarcomere length increases. It has been suggested that this phenomenon may be due to myofilaments moving closer together at longer lengths, thereby enhancing the probability of favorable acto-myosin interaction, resulting in increased calcium sensitivity. Accor...
Tension outputs were measured in skinned crayfish muscle fibers exposed to solutions variously buffered for both Mg-adenosine triphosphate (ATP) and Ca. Two types of data are shown, relating tension and substrate concentration with different levels of Ca present, or tension and calcium concentration at different levels of substrate. The data are fitted by curves calculated from a general equati...
There has been significant development in the facial recognition technology during past few decades. This widely used by different organizations and governments for defense, security, surveillance projects. Furthermore, it now incorporated into our daily usages, such as consumer applications, personal data protection, or cyber-security, particularly while using smartphones. Most of these system...
Skinned fibers from the normal human heart with the f3-myosin heavy chain (ventricular fibers) revealed both a higher force generation per cross section and a higher Ca2' sensitivity than skinned fibers with the a-myosin heavy chain (atrial fibers). The relation between isometric ATPase activity and isometric tension of atrial fibers was higher than that of ventricular fibers. Since the ATPase-...
