Newswise — Many adult congenital heart patients have undergone multiple heart surgeries by the time they reach their 20s. Each time surgeons operate on the heart, the risk of complications increases. A new valve recently approved by the Food and Drug Administration, now gives these patients a new way to manage their disease without having to undergo open heart surgery.
Many adults with congenital heart disease are born with a malformation of the pulmonary valve, which sits between the heart and lungs. Most have undergone open heart surgery during childhood to restore blood flow to the lungs, and often require a second and third open heart surgery to replace this valve. Because of advancements in heart surgery over the past 50 years, more and more of these patients are making it to the adulthood for the first time in history.
The new Melody Transcatheter Pulmonary Valve, which is delivered through a catheter and requires only a small incision, is a new technique that is bringing new hope to these patients.
The first Melody Valve at Methodist DeBakey Heart & Vascular Center in Houston was recently implanted by Dr. C. Huie Lin, an adult congenital heart disease specialist, in a young man who had already had three open heart surgeries for congenital heart disease. Read the rest at Newswise!
I never thought that I would find a reason to like flies, but this article has me thinking of them in a new way. God has a reason for everything and perhaps we are finally beginning to realize that even flies are important!
Their discovery, detailed this week in the open-access journal PLOS ONE (open access), was made in the laboratory fruit fly Drosophila. But the biologists say many of the same genes that regulate biological processes in the hard exoskeleton, or cuticle, ofDrosophila also control processes in human skin.
“Many of the key molecules and proteins involved in Drosophila wound healing are involved in mammalian wound healing,” says Rachel Patterson, the first author who published the paper with Michelle Juarez and William McGinnis, a professor of biology and interim dean of the Division of Biological Sciences. “The genetics of Drosophila are not as complicated as mammalian genetics, so it’s easier to attribute specific biological functions to individual genes.” Read the rest at Discovery of wound-healing genes in flies could mitigate human skin ailments | KurzweilAI.
A doctor says people can be revived several hours after they have seemingly died, BBC News reports. Should this change the way we think about death?
“While 45 minutes is absolutely remarkable and a lot of people would have written her off, we now know there are people who have been brought back, three, four, five hours after they’ve died and have led remarkably good quality lives,” says Dr Sam Parnia, the director of resuscitation research at Stony Brook University in New York.

Lab-grown livers have come a step closer to reality thanks to a 3D printer loaded with cells, New Scientistreports.
Created by Organovo in San Diego, California, future versions of the system could produce chunks of liver for transplant.
The mini-livers that Organovo made are just half a millimeter deep and 4 millimeters across but can perform most functions of the real thing.Read more at 3D printer makes tiniest human liver ever | KurzweilAI.

Engineers at the University of California, San Diegohave invented a “nanosponge” capable of safely removing a broad class of dangerous toxins from the bloodstream — including toxins produced by MRSA, E. coli, poisonous snakes and bees.
These nanosponges, thus far studied in mice, can neutralize “pore-forming toxins,” which destroy cells by poking holes in their cell membranes. Unlike other anti-toxin platforms that need to be custom-synthesized for individual toxin type, the nanosponges can absorb different pore-forming toxins regardless of their molecular structures.

This image reveals “rootless cones,” which form on lava flows that interact with subsurface water. They are in depressions because subsequent lava flowed around the base of the cones, then “inflated.” Lava inflation is a process where liquid is injected beneath the solid (thickening) crust and raises the whole surface, often raising it higher than the topography that controlled the initial lava emplacement.
This scene is in Amazonis Planitia, a vast region covered by flood lava. The surface is coated by a thin layer of reddish dust, which avalanches down steep slopes to make dark streaks.
New injectable hydrogel encourages regeneration and improves functionality after a heart attack | KurzweilAI
University of California, San Diego bioengineers havedemonstrated in a study in pigs that a new injectable hydrogel can repair damage from heart attacks, help the heart grow new tissue and blood vessels, and get the heart moving closer to how a healthy heart should.
The gel is injected through a catheter without requiring surgery or general anesthesia — a less invasive procedure for patients.
There are an estimated 785,000 new heart attack cases in the United States each year, with no established treatment for repairing the resulting damage to cardiac tissue.
Lead researcher Karen Christman, a professor in the Department of Bioengineering at the UC San Diego Jacobs School of Engineering, said the gel forms a scaffold in damaged areas of the heart, encouraging new cell growth and repair. Because the gel is made from heart tissue taken from pigs, the damaged heart responds positively, creating a harmonious environment for rebuilding, rather than setting off a chain of adverse immune system defenses.
“While more people today are initially surviving heart attacks, many will eventually go into heart failure,” said Christman. “Our data show that this hydrogel can increase cardiac muscle and reduce scar tissue in the region damaged by the heart attack, which prevents heart failure. These results suggest this may be a novel minimally invasive therapy to prevent heart failure after a heart attack in humans.” Read the rest at New injectable hydrogel encourages regeneration and improves functionality after a heart attack | KurzweilAI.

In last 2 days exploding fireballs were reported on all sides of the world – Russia, Kazakhstan, Japan, Australia, Cuba, South Africa, Morocco, Germany, Switzerland, northern Italy, Netherlands, Belgium, UK…
An enormous fireball was reported by numerous witnesses over Belgium, Netherlands and Germany on February 13, 2013. The sight lasted from 10 – 20 seconds. There were two separate fragmentations that shone brightly, one witness reported. Apparently it was part of Soyuz rocked it still remains unclear what it was exactly. One Soyuz was launched but on February 11th: The 1800th flight of a Soyuz launch vehicle was performed on Monday, 11 February 2013 from the Baikonur Cosmodrome in Kazakhstan at 18:41 Moscow time (15:41 Paris time). Arianespace and its Russian partners report that the Progress cargo spacecraft was accurately placed on the target orbit for another mission to the International Space Station. This was the second Soyuz family mission in 2013. Detailed reports here.
Russian exploding fireball was covered in-depth and most people only heard about that one. First reports came early February 15, 2013 at about 01:00 UTC. During the morning hours Russian military discovered a 6-meter crater, normal background radiation was reported. Russian Academy of Science said the meteorite weighed 10 tons before it entered Earth’s atmosphere but some reports mentioned 50 tons. The meteorite exploded nine times, starting at an altitude of 55 kilometers. Read the rest at The Watchers – Exploding fireballs reported all over the globe: Japan, Russia, Cuba….
Scientists determined in human cell culture and animal studies that a protein lures zinc into key cells that are first-responders against infection. The zinc then interacts with a process that is vital to the fight against infection and by doing so helps balance the immune response. This study revealed for the first time that zinc homes in on this pathway and helps shut it down, effectively ensuring that the immune response does not spiral out of control. The team led by Ohio State University researchers also found that if there is not enough zinc available at the time of infection, the consequences include excessive inflammation. In this research, zinc’s activity was studied in the context of sepsis, a devastating systemic response to infection that is a common cause of death in intensive-care unit patients. But scientists say these findings might also help explain why taking zinc tablets at the start of a common cold appears to help stem the effects of the illness. “We do believe that to some extent, these findings are going to be applicable to other important areas of disease beyond sepsis,” said Daren Knoell, senior author of the study and a professor of pharmacy and internal medicine at Ohio State. “Without zinc on board to begin with, it could increase vulnerability to infection. But our work is focused on what happens once you get an infection – if you are deficient in zinc you are at a disadvantage because your defense system is amplified, and inappropriately so. “The benefit to health is explicit: Zinc is beneficial because it stops the action of a protein, ultimately preventing excess inflammation.” While this study and previous work linking zinc deficiency to inflammation might suggest that supplementation could help very sick ICU patients, it’s still too early to make that leap.

It is fairly easy for those who feel no real responsibility for their actions, or those who don’t believe that they will have to face judgment someday, to tell the world that life does not begin at conception and that the baby in the womb is just a bunch of cells. What they neglect to tell is the rest of the story and that is that we are all a bunch of cells but that life itself is scientifically established with the dividing of those cell, at least human life is. They like to convince people that abortion is acceptable not because they don’t believe in life, but because they don’t believe in anything but themselves. To admit to something greater would be to admit to the possibility that they might have to take some responsibility for their actions at some time. They prefer to live a life that is simply filled with whatever they desire, the mentality that says if it feels good, do it. If there is an unwanted reaction to that lifestyle, it is easier to dispose of if you can deny the reality of it. These same people will also argue the worth of life or the quality of life. As if by some accidental arrangement of their brains, they have the right to decide who is worthy and what quality of life they have. They would like to be able to euthanize the disabled, the elderly or simply those that they find burdensome. These are the lawless of our society. The ones who want to do as they will, if they can change the laws they will, if they can not, the laws are something to be gotten around. Their only value on life is what it brings them. They would rather treat the Word of God as a history book that doesn’t fit todays lifestyle, rather than a book by the Creator that emcompasses all of creation itself and warns regularly of the consequences of our actions. Please take time to visit the site and consider the book written by Tommy Mitchell MD and God bless! An excerpt is below!!!
Who Is More Human?
Life is a continuum. From the season of growing in the womb to being born, from playing as a child to growing older, each stage of life seems to blend gracefully (or not so gracefully in my case) into the next. Life progresses and time passes, culminating in death. Death, a very visible end point, is more easily defined than the point at which the continuum of human life begins.
Where is the starting point? If life is indeed a continual process, can we not just work backward to its beginning? There are a variety of opinions about life’s beginnings. Many say life begins at conception. Others argue strongly that life does not start until implantation in the womb. Still others say that human life begins only when the umbilical cord is cut, making the newborn child an independent agent. How is fact separated from opinion?
Perhaps another way to ask the question is, when do we become human? Certainly a child sitting on grandpa’s knee or a fully grown adult would be considered human. Is the adult more human than the child? Of course not. No reasonable person would consider the child to be less human. At what point along the journey did this child become human? Was it at conception, somewhere during his development, or at birth?

Have you ever wondered what triggered the Genesis Flood? Genesis 7:11 tells us that a unique geologic event took place at the same moment as the Flood began: “In the six hundredth year of Noah’s life, in the second month, the seventeenth day of the month, on that day all the fountains of the great deep were broken up, and the windows of heaven were opened.”
Most creation geologists believe that the opening of “the fountains of the great deep” refers to the breakup of the earth’s crust into plates.1The subsequent rapid, catastrophic movement of these plates would have released huge quantities of hot subterranean waters and molten rock into the ocean. As the hot water gushed through the fractured seafloor, the water flashed into superheated steam and shot high into the atmosphere as supersonic steam jets, carrying sea water that eventually fell as rain.
But what catastrophe might God have used to cause the earth’s crust—many miles thick—to crack? Some have suggested a meteorite or asteroid impact of unprecedented size and scope.2Do we find any evidence? Geologists have discovered some gargantuous remnant craters and piles of debris, leftover from massive impacts that easily fit the bill. Read the rest at Answers in Genesis
I think that this is a fascinating story on many levels. We constantly find those who argue with us that “Even God has to obey the laws.” I find that odd because they can’t seem to get their heads around the fact that the One who created the laws surely can fathom what they are and how they work. In their arrogance they assume that man has discovered everything that there is to discover and therefore because they see limits, think that He is limited. The creator of time, the universe and everything in it, is so far beyond what we can perceive that it is foolish to try to bind Him into something that will fit into some small box so that we can bundle Him up and show Him off as some kind of tool that faulty men can use to their own advantage. There are so many things that we are just beginning to understand and the great I am has no need for the limits of time that we see around us.
