|WASHINGTON Cheap Nike Air Max Online , July 6 (Xinhua) -- British researchers said Thursday that they had identified a possible new target for the development of novel drugs against mosquito-borne malaria.
When malaria parasites invade red blood cells, they form aninternal compartment in which they replicate many times beforebursting out of the cell and infecting more cells, according totheir study published in the journal PLOS Pathogens.
In order to escape red blood cells, the parasites have to breakthrough both the internal compartment and the cell membrane usingvarious proteins and enzymes.
Scientists at the Francis Crick Institute and the London Schoolof Hygiene & Tropical Medicine have identified a key proteininvolved in this process.
Disrupting this protein reduces the efficiency of parasiteescape, slowing down the rate of infection Cheap Air Max 2017 Online , they found.
"The parasite sits in its internal compartment inside the cell,surrounded by lots of proteins, a bit like a baby surrounded byamniotic fluid," Mike Blackman, group leader at the Francis CrickInstitute Cheap Air Max 2018 Online , said in a statement. "We focused on the most commonprotein, known as SERA5, assuming that it probably has an importantrole since there is so much of it."
The team used genetic tools to knock out the gene responsiblefor producing SERA5 in malaria parasites and then took time-lapsevideo of the cells under a microscope.
They found that the parasites broke through the membranes fasterthan normal but many got stuck on their way out, meaning that theywere less likely to invade other red blood cells.
Since malaria parasites don't survive for long outside red bloodcells, getting stuck on their way out means that they might diebefore they have a chance to infect another cell Cheap Air Max Online , the teamsaid.
It turned out that parasites lacking SERA5 were about half asefficient as normal parasites at escaping and infecting newcells.
The team is now working with British pharmaceutical company GSKto see if SERA5 or one of the enzymes that it controls could be apotential drug target.
"Drug resistant malaria is a huge problem, so there is a realpush to develop new drugs that work in a different way," Blackmansaid. "None of the current antimalarials work by preventing theparasites from escaping red blood cells, so we think that theproteins and enzymes that help the parasites break free could bevaluable new targets that we can design drugs for."
MELBOURNE, Nov. 24 (Xinhua) -- Real Madrid will play in a pre-season international tournament at Australia's 100 Cheap Nike Air Max 2017 ,000-capacity Melbourne Cricket Ground next year, organizers said on Monday.
The European champions will play in the July 18-24 International Champions Cup against an English Premier League side and Italian Serie A outfit.
In the 37 years that I have been counseling couples, I have discovered that there are only a few issues that are true relationship deal-breakers. Many of the issues that tear relationships apart are not actual deal-breakers. Rather, most divorces and breakups are the result of one or both partner芒鈧劉s unwillingness to learn from the conflicts that exist in all primary relationships. But some conflicts and differences are actual deal-breakers.HAVING CHILDRENEarly in my career as a psychotherapist, I worked with Mary and Cal. Mary and Cal met when Mary was 38 and Cal was 47. Cal had been married before and had two adult children Cheap Nike Air Max 2018 , while Mary had never been married. Cal made it very clear to Mary that he did not, under any circumstances, want more children. Mary seemed to accept this, but secretly hoped to change Cal芒鈧劉s mind once they were married. A year after they were married, Mary brought up the issue of having children. Cal was appalled. He felt angry Cheap Nike Air Max , trapped and betrayed by Mary芒鈧劉s secret hope, as well as by her dishonesty. Mary begged and pleaded, hoping Cal芒鈧劉s love for her would soften his position. But he stayed committed to his decision not to have any more children.This situation has a very sad ending. Mary was devastated. She loved Cal, but having children was actually extremely important to her. She didn芒鈧劉t want to leave him and she couldn芒鈧劉t let go of wanting a child. The stress of the situation eventually eroded her immune system and she died of ovarian cancer of few years after bringing up the baby issue. I learned a lot from Mary and Cal芒鈧劉s experience. I learned that the baby issue is a deal-breaker. It is not healthy for someone who really wants a baby to give that up, and it is not healthy for someone who does not want a baby to go along with having one. This deep and basic issue needs to be dealt with head-on Cheap Air Max 2017 , early in a relationship, before people move ahead with commitment and marriage.WORKRhonda and Fred fell in love in their late 30芒鈧劉s. Each had jobs that they loved and that were very important to them. Fred was the vice-president of a large company, while Rhonda had a flourishing practice as a pediatrician. They both lived in Los Angeles. All seemed fine until an incredible opportunity opened up for Fred 芒鈧€?one that he had always dreamed of. The problem was that it meant moving to New York. Fred芒鈧劉s work became a deal-breaker.Some people can commute and maintain a relationship, but this was not realistic for Rhonda and Fred, since they both wanted to have children. They realized that if either of them gave up the work they loved Cheap Air Max 2018 , they would feel very resentful. They had no choice but to end the relationship. Even though they loved each other, they recognized that their relationship would soon erode if one of them gave themselves up.BETRAYALDishonesty and infidelity can often be deal-breakers, depending upon the situation. Some people can learn from and grow through these difficult situations, while for others the wound is too deep to repair.Mandy and Hal were in their 50芒鈧劉s when they met and fell in love. Both were in unhappy long-term marriages, which they decided to leav.
