Arctic Heart

Professor Quignard and his team of researchers have been studying "PPM", an immunizing protein produced by penguins, for a Nobel Prize research project. Christophine, a shy and young PhD student who is secretly in love with Quignard, decides to inject herself with the penguin genome, in an attempt to advance the professor's research and to get closer to him. Amidst all the experiments she wants him more and more, whereas the professor is always concerned about the results of his experiments. It breaks her heart that even after all she has done for him, he is so indifferent towards her but she decides to keep her feelings to herself. The results finally lead him to his goals, and he is selected to win the Nobel Prize, but Christophine realises that her body is changing and reacting to the experiments, and she decides to stay alone, closing herself to everything. When the professor finds out, he tries every possible way to save her but he has no option left other than sending her to Antarctica to live with penguins. The professor then injects himself with the same drug that Christophine took and goes and lives with her in Antarctica, after having grasped his feelings for her.

President Biden's administration is just one step away from approving ConocoPhillips' dangerous Willow Oil Project in the heart of America's Arctic. Let the White House and the Department of the Interior know you want President Biden and Secretary of the Interior Debra Haaland to continue to show climate leadership and reject this climate disaster. A final decision will be made on Willow by EARLY MARCH 2023! Don't delay taking the actions below!

Aortic valve stenosis causes a thickening and narrowing of the valve between the heart's main pumping chamber (left ventricle) and the body's main artery (aorta). The narrowing creates a smaller opening for blood to pass through. Blood flow from the heart to the rest of the body is reduced or blocked. Typically, the aortic valve has three cusps (tricuspid aortic valve), but some people are born with an aortic valve that has two cusps (bicuspid aortic valve).

Aortic valve disease is a type of heart valve disease. In aortic valve disease, the valve between the lower left heart chamber (left ventricle) and the main artery to the body (aorta) doesn't work properly.

Make an appointment with a health care provider if you have signs or symptoms of valve disease, such as shortness of breath, fatigue after activity, or sensations of a pounding or an irregular heartbeat. Sometimes the first signs of aortic valve disease are related to heart failure. See a health care provider if you have fatigue that doesn't get better with rest, shortness of breath, and swollen ankles and feet, which are common symptoms of heart failure.

A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings.

In aortic valve stenosis, the aortic valve opening is narrowed (top row). The narrowing requires increased pressure within the heart to pump blood across a smaller opening. Eventually this reduces the heart's ability to pump blood to the body. This is similar to attaching smaller and smaller nozzles to the end of a garden hose (bottom row). The narrowing from the nozzle slows the forward flow of water and results in pressure buildup within the garden hose.

Each valve has flaps (cusps or leaflets) that open and close once during each heartbeat. Sometimes, a valve doesn't open or close properly. This can reduce or block blood flow through the heart to the rest of the body.

In aortic valve disease, the valve between the lower left heart chamber (left ventricle) and the body's main artery (aorta) doesn't work properly. The valve may be thickened and stiff (stenosis) or it may not close properly, causing blood to flow backward.

John Englander is an oceanographer, consultant and leading expert on sea level rise. His broad marine science background coupled with explorations to Greenland and Antarctica allows him to see the big picture of sea level rise and its societal impacts.

Materials and methods: In order to study ANS responses during diving in Arctic water temperatures, we retrospectively analyzed repeated 5-min heart rate variability (HRV) measures and the mean body temperature from dives at regular intervals using naval diving equipment measurement tests in 0C water. Three divers performed seven dives without physical activity (81-91 min), and two divers performed four dives with physical activity after 10 min of diving (0-10 min HRV recordings were included in the study).

Nearly 60 million people worldwide1 are affected by atrial fibrillation (AF). AF is a progressive disease, meaning over time patients can experience more frequent, and longer episodes, and medication as well as catheter ablation can become less effective. Additionally, AF is associated with serious complications including heart failure, stroke and increased risk of death2-5.

Time-domain measures were recorded: (a) Mean heart rate (HRmean) (bpm), (b) Standard deviation of NN intervals (SDNN) (ms), and (c) Root mean square of successive RR interval differences (RMSSD) (ms).

When estimating the SNS activity of the diver from the LF-band and the LF/LH ratio, these did not show a significant increase at the beginning of the dives. This finding is in line with an earlier finding with experienced divers (Schipke and Pelzer, 2001). On the other hand, SNS activity is only one of the factors that contribute to the LF band. The significant increase in mean heart rate at the beginning of the dives suggests that there actually was a strong activation of the SNS. This is in line with most earlier observations of the diving reflex and sensation of cold also causing an SNS activation (Boussuges et al., 2007; Buchholz et al., 2017). After the first SNS response, the mean heart rate and LF/LH ratio suggested that SNS activity actually decreased over time. Our finding indicated that, for our experienced subjects, cold was, after the first responses to diving, neither a physiological nor a psychological stress factor. On the other hand, the dives were not deep nor demanding. Physical stress at the beginning of a cold-water dive, together with the diving reflex and cold stress-induced SNS activation, leads to a quick concurrent increase in both PNS and SNS activity. This, in turn, is a known risk factor for arrhythmia and sudden death (Buchholz et al., 2017; Kane and Davis, 2018). For this reason, at the beginning of a cold-water dive, we recommend an adaptation phase before tasks requiring physical stress. Furthermore, we recommend that special emphasis be placed on evaluating cardiovascular risk factors and incipient signs of heart disease for persons who dive in Arctic conditions. In the fit-to-dive evaluations of Naval divers, we recommend strict cardiovascular criteria.

Stith is a firm believer that a truthful story from the heart is the one people most need to hear. If you're ready to meet the Arctic heart to heart, and to learn what you can do to support the people who live there, allow these stories to guide you.

This is the winter world in which the wood frog must survive. Remember, frogs are cold blooded, so their body temperature is about the same as the surrounding air. How do these delicate little creatures endure the intense, protracted, iron-cold subarctic winter?

Researchers are also interested in how the wood frog's body can stop blood circulation and start it again many months later without blood clots or other injuries. Understanding the mechanism which allows this could be valuable for treating people after their blood flow is temporarily halted by heart attack or stroke.

We recently watched a show about arctic animals and my kids thought the Arctic Fox was adorable. We decided it would be fun to make one as a craft so we put together this Paper Plate Arctic Fox Craft. If your kids love arctic animals, you might also enjoy our Polar Bear Mask or Newspaper Polar Bear Craft.

The Arctic region, commonly referred to as the High North, is becoming more contested than ever before. The Arctic encompasses the lands and territorial waters of eight countries on three continents. Unlike the Antarctic, the Arctic has no land mass covering its pole (the North Pole), just ocean. The region is home to some of the roughest terrain and harshest weather on the planet.
