Whiteheart denned 120 yards from a house with a telephone and electricity. The homeowner let Ely researchers and Discovery Channel install an infra-red den cam and send images of Whiteheart to Discovery Channel headquarters in Maryland and on to the internet.
Ely researchers and the public learned together as they watched this hibernating bear from indoor comfort. The web site received over a million hits as people downloaded images of Whiteheart from December 6, 1999, to April 8, 2000.

Whiteheart had entered the den with a good layer of fat, which gave her energy to burn, so she did not have to reduce her metabolism as much as skinny bears do. She turned three years old in January, raising the possibility of cubs, but she did not give birth.
Since that time, only one bear has denned close enough to a telephone and electricity to repeat the project. In the fall of 2007, gentle Solo and her nearly year-old cubs denned under an unoccupied cabin. However, the owner was concerned about liability and the bears were removed.

Objective: This study tested four hypotheses: (1) a high percentage of 9- and 10-year-old girls are already trying to lose weight; (2) more white tha black girls are trying to lose weight; (3) more black than white girls are trying to gain weight; and (4) weight modification efforts of preadolescent girls are influenced by factors other than race, such as maternal criticism, body dissatisfaction, and socioeconomic status.
Results: Black girls were taller and heavier and showed earlier signs of puberty than white girls but were less dissatisfied with their weight, body shape, and body parts. Approximately 40% of 9- and 10-year-old girls reported that they were trying to lose weight. Of those girls classified in the fourth quartile of body mass index (BMI), approximately 75% were trying to lose weight. After adjusting for BMI, no significant black and white differences in the prevalence of those trying to lose weight were seen, but significantly more black than white girls were trying to gain weight. Multiple logistic regression identified a high BMI, the mother telling her she was too fat, and body dissatisfaction as the major factors associated with trying to lose weight. However, chronic dieting was only associated with a high BMI and the mother telling her she was too fat. An important predictor of girls who were trying to gain weight was being black, along with having a low BMI and the mother telling her she was too thin.
Conclusions: Attempts at gaining weight are much more frequent among black preadolescent girls than their white counterparts. No racial difference was found between black and white girls in their efforts to lose weight or to practice chronic dieting. Because approximately 40% of 9- and 10-year-old girls are already trying to lose weight, pediatricians should capitalize on this concern by providing information on proper weight control techniques. Educational efforts should be directed to both the mother and the child, because weight control efforts of preadolescent girls are stimulated by their mothers' admonitions of being too fat or too thin. The high prevalence of dieting among the thinnest adolescent girls also needs to be addressed by pediatricians.
Currently none of these little heart card symbols is displayed in color as an emoji icon on any device or software. Just black on white like the usual text symbols. I also listed the symbols for the four playing card suits, including the heart symbol suit and including the white variation. The non-white variation is usually rendered in color as a text emoji icon where emoji text font is available.
I think, everybody who ever fell in love knows that it gives a strong feeling of harmony. Of calming safety and satisfaction. You feel as if you have ultimately found the right person you can share your life with.
And this feeling is present in your very heart, because of the hormonal, neuromediatory and whatever influences your brain makes upon on it.This is the key to why heart symbol is so popular. It's symmetric aesthetically pleasing shape that looks a lot like human heart, although it's far from being exactly like it. Interestingly, because of the symbolic symmetry and division in the middle - it takes two halfs to make the whole. This gives birth to further symbolic interpretations.
A comparison of the first-ever image of a black hole released this week by the Event Horizon Telescope collaboration et al. and a cardiac nuclear imaging exam. Left is the black hole, and right is a similar nuclear imaging exam of the heart showing a similar ischemic perfusion defect to the black hole.
This week, cardiologists learned for the first time they have been examining black holes for decades and did not know it. Many cardiologists and radiologists did a double take when they saw the ground-breaking first image of a black hole released by the U.S. National Science Foundation. While the unclear image of the dark circle surrounded by a bright neon orange and yellow was a new sight for many in science, it looked suspiciously similar to the standard nuclear myocardial perfusion imaging (MPI) exams many physicians have been looking at daily for the past 40 years.
Nuclear imaging scans are a little less mysterious and technically challenging to those in the know. But the close similarities to this image and nuclear MPI prompted many cardiologists and radiologists to post comments about it on clinical social media group pages. Many offered a preliminary diagnosis for the Messier 87 galaxy.
At first glance, the galaxy appears to have a perfusion defect on the anterior wall of the left ventricle. However, several others piped in with comments that the galaxy clearly has large breasts and the perceived perfusion defect is actually an attenuation artifact caused by overlapping breast tissue, which causes issues with detection/photon counts to render the image properly, a common issue in this type of nuclear imaging.
No one really wants to get their medical diagnosis from people they don't know on the internet, so I was really looking for a top expert's opinion to help with the clinical diagnosis of the Messier 87 galaxy black hole. I reached out to Kim Allan Williams, Sr., M.D., MACC, FAHA, MASNC, FESC, James B. Herrick Professor, chief, Division of Cardiology, Rush University Medical Center, and former president of both the American College of Cardiology (ACC) and American Society of Nuclear Cardiology (ASNC).
Nuclear perfusion scans use SPECT or PET imaging detectors to visualize the radioactivity from radio tracers injected into the patient. The images show blood perfusion in the tissue and metabolic uptake of the radiotracer by the heart muscle.
Ironically to see the same image, all she had to do was visit with any cardiology department and they could have fixed her up with a rarely easy to open CD of a similar image of the "black hole of the left ventricle," complete with quantification of the defect in the imaging report.
Problem/Condition: Heart disease is the leading cause of death in the United States. In 2015, heart disease accounted for approximately 630,000 deaths, representing one in four deaths in the United States. Although heart disease death rates decreased 68% for the total population from 1968 to 2015, marked disparities in decreases exist by race and state.
At the national level, heart disease death rates for blacks and whites were similar at the start of the study period (1968) but began to diverge in the late 1970s, when rates for blacks plateaued while rates for whites continued to decrease. Heart disease death rates among blacks remained higher than among whites for the remainder of the study period. Nationwide, the black-white ratio of heart disease death rates increased from 1.04 in 1968 to 1.21 in 2015, with large increases occurring during the 1970s and 1980s followed by small but steady increases until approximately 2005. Since 2005, modest decreases have occurred in the black-white ratio of heart disease death rates at the national level. The majority of states had increases in black-white mortality ratios from 1968 to 2015. The number of states with black-white mortality ratios >1 increased from 16 (40%) to 27 (67.5%).
Interpretation: Although heart disease death rates decreased both for blacks and whites from 1968 to 2015, substantial differences in decreases were found by race and state. At the national level and in most states, blacks experienced smaller decreases in heart disease death rates than whites for the majority of the period. Overall, the black-white disparity in heart disease death rates increased from 1968 to 2005, with a modest decrease from 2005 to 2015.
Public Health Action: Since 1968, substantial increases have occurred in black-white disparities of heart disease death rates in the United States at the national level and in many states. These increases appear to be due to faster decreases in heart disease death rates for whites than blacks, particularly from the late 1970s until the mid-2000s. Despite modest decreases in black-white disparities at the national level since 2005, in 2015, heart disease death rates were 21% higher among blacks than among whites. This study demonstrates the use of NVSS data to conduct surveillance of heart disease death rates by race and of black-white disparities in heart disease death rates. Continued surveillance of temporal trends in heart disease death rates by race can provide valuable information to policy makers and public health practitioners working to reduce heart disease death rates both for blacks and whites and disparities between blacks and whites.
Heart disease is the leading cause of death in the United States (1). In 2015, heart disease accounted for approximately 630,000 deaths, representing one in four deaths (1). Nationally, racial disparities in heart disease mortality have persisted since at least the 1980s (2) and have been documented as the leading contributor to differences between blacks and whites in life expectancy (3). The National Academy of Medicine (NAM), formerly known as the Institute of Medicine, and Healthy People 2020 have both called for increased understanding of health disparities by race and geographic area (4,5). NAM has called for surveillance systems that can measure disparities in heart disease by race and by contextual factors such as place of residence (4). Documenting trends in heart disease death rates by race and state provides valuable information to policy makers and public health practitioners for promoting continued decreases both for blacks and whites, along with decreases in disparities between blacks and whites, in heart disease mortality. 152ee80cbc
