What an MLB source said about the D-backs’ trade haul for Greinke D-backs president Derrick Hall: Franchise ‘still focused on Arizona’ Peterson’s defensive teammate, Darnell Dockett, also wasn’t shy on sharing his feelings regarding the NFL’s replacement officials on his Twitter account, @ddockett.This is what the NFL has come down to, &yet they tell you to respect the shield! Lol. But they’ll try to fine us for everything thing we do.— DARNELL DOCKETT (@ddockett) September 25, 2012 0 Comments Share Cardinals expect improving Murphy to contribute right away Nevada officials reach out to D-backs on potential relocation Then there’s safety Rashad Johnson, who decided to call out the Packers’ offensive line.

Take some responsibility on ur own faults!! #9— Rashad Johnson (@49foyamind49) September 25, 2012 Top Stories The controversial final play in the Seattle-Green Bay game marks the end of a wild weekend in the NFL and highlights the on-going divide between the league and its players regarding the current in-game officials.As ESPN senior analyst Chris Mortensen reported, commissioner Roger Goodell and league negotiators met for 10 hours with the NFL Referees Association in New York on Sunday. Both sides are still far apart on a new CBA agreement, and as of now the replacement officials are scheduled to work through Week 5. And fresh off his game-changing, 93-yard fumble return for a touchdown, safety James Sanders (@JamesSanders36) shared his teammates sentiments following the final play in Seattle.The NFL players and the fans of the NFL deserve better then this!!!!— James Sanders (@JamesSanders36) September 25, 2012 Here’s cornerback Patrick Peterson’s thoughts on his official Twitter page,@RealPeterson21. Com’on can we please get the real refs back. Destroying the game that we all grew to love. WOW!!!!!!— Patrick Peterson (@RealPeterson21) September 25, 2012 Even with a nice 3-0 start to their season, plenty of Cardinal players had their eyes glued to the television on Monday night, as their NFC West rivals, the Seahawks, took on the Green Bay Packers.And after the game ended on a controversial game-winning touchdown pass from Russell Wilson to Golden Tate – that appeared to be intercepted by the Packers’ M.D. Jennings – several Redbirds weren’t exactly rejoicing with their division brethren.
May 4 2018While the global health community has made great strides toward eradicating malaria through prevention and treatment strategies, rapid and inexpensive methods to diagnose submicroscopic malaria in individuals who have no clinical symptoms and undetectable levels of disease-causing parasites in their blood remain an unmet need.With the unexpected discovery of a panel of peptides from several proteins encoded by the parasite that causes malaria, new research underway at Seattle Children’s Research Institute could pave the way for a rapid screening test capable of diagnosing submicroscopic infections.Such a diagnostic test could permit the widespread screening of all individuals in high-risk regions – a practice global health experts agree is likely required to eradicate malaria. It could also provide a way to diagnose submicroscopic malaria infections during pregnancy, which bring substantial health risks for the pregnant woman, her fetus, and the newborn child.Exosomes as a marker of infectious diseaseA team led by Dr. Serge Barcy, a principal investigator in the Center for Global and Infectious Disease Research at Seattle Children’s, first uncovered the novel proteins associated with malaria in their study of a promising source of diagnostic biomarkers known as exosomes.Healthy and infected cells continuously secrete exosomes carrying genetic information or protein content as a way to communicate with other cells. Previous studies have also suggested that exosomes from infected cells may play a significant role in disease progression.Since many of the rapid tests in use today need high levels of the disease-causing parasite, virus or bacteria circulating in the blood to detect disease, scientists believe that identifying changes in the expression of the always present exosomes circulating in human plasma could offer a better way to detect submicroscopic infections.Unexpected finding leads researchers to malariaIn his study, Barcy initially set out to determine if changes in the expression of a type of small RNA frequently found in exosomes and associated with disease known as microRNA (miRNA) could provide a reliable way to detect Kaposi’s sarcoma-associated herpesvirus infection (KSHV or HHV-8). In individuals infected with HIV, KSHV commonly progresses into a cancer known as Kaposi’s sarcoma, which remains prevalent in Sub-Saharan African populations.Related StoriesScientists identify malaria’s Achilles’ heelNew diagnostic tool helps develop improved RDTs and support public health surveillanceProteasome inhibitors show potential for combating multidrug-resistant malariaThe study took an unexpected turn when researchers analyzed the genetic content of exosomes present in blood samples from a Uganda study population. Since miRNAs are typically found in plasma exosomes, researchers expected to find a high percentage of the small RNA in the exosomes purified from the plasma of study participants.Instead, researchers were perplexed to find another type of small RNA in abundance, leading them to look at the protein content of the exosomes. It was here they discovered several peptides associated with a separate infection – Plasmodium falciparum, the primary parasite responsible for malaria in Africa.Follow-up studies supported by renowned malaria expertAccording to a paper published in the scientific journal, PLOS One, none of the protein biomarkers revealed in this study have previously been detected in blood samples from patients diagnosed with malaria.To test the diagnostic potential of the new biomarkers, Seattle Children’s is collaborating with a research group from Osaka City University in Japan led by the world-renowned malaria expert, Dr. Akira Kaneko. Kaneko’s lab has provided malaria samples that researchers in Seattle can analyze for the presence of the newly identified biomarkers.If their research is successful, it could lead to the development of a rapid diagnostic test to identify malaria infections in individuals without any symptoms. Currently, no rapid screening method exists to diagnose malaria infection in individuals with low levels of parasites in their blood.Implications for malaria eradication effortsThe results from Barcy’s study also indicate that ongoing efforts to eliminate endemic disease may benefit from addressing the dynamic interactions between infections, especially in geographic regions where multiple infections are widespread.”While many have the goal to eradicate malaria, it’s unlikely we’ll achieve optimal prevention and treatment strategies by focusing on malaria in isolation,” Barcy said. “Our work shows we can’t simply extract one disease to study. We must look at the interactions of all infections taking place in the host.”Source: http://pulse.seattlechildrens.org/surprising-discovery-could-improve-malaria-detection-worldwide/
