Researchers Develop Herpes Evolution Model
March 28th 2017It's an axiom of the infectious disease research community that wherever humans go, germs are likely to follow. Such is the case with the herpes virus family. There are two main strains, herpes simplex virus 1 and 2 (HSV 1 and 2). HSV1 is mostly transmitted by mouth, and seen most often in the common cold sores (affecting two-thirds of the world's population). HSV-2 is the main culprit of genital herpes (global prevalence of 11 percent), but has even been used to help verify the accepted ancient migrations of humans "Out of Africa" dogma that began about 80,000 to 50,000 years ago.
TSRI Researchers Develop New Method to 'Fingerprint' HIV
March 28th 2017HIV is a master of disguise. The virus uses a shield of sugar molecules, called glycans, to hide from the immune system and block antibodies from attacking it. Now, scientists at the Scripps Research Institute (TSRI) have developed a method to analyze the glycan shield on HIV's protective outer glycoprotein, developed as a potential HIV vaccine candidate.
Researchers Identify Proteins That Enable Malaria Parasites to Penetrate Cell Walls
March 28th 2017Researchers have identified proteins that enable deadly malaria parasites to 'walk through cell walls' - a superpower that was revealed using the Institute's first insectary to grow human malaria parasites. The research has identified two parasite proteins that are the key to this superpower. The proteins could be targeted to develop much-needed antimalarial drugs or vaccines.
Antimicrobial Resistance Diagnostic Challenge Selects 10 Semifinalists in First Phase of Competition
March 28th 2017Ten semifinalists have been selected in the first phase of the Antimicrobial Resistance Diagnostic Challenge, a federal prize competition that will award up to a total of $20 million in prizes, subject to the availability of funds, for innovative rapid, point-of-need diagnostic tests to combat the emergence and spread of drug-resistant bacteria. The semifinalists were selected for their concepts for a diagnostic based on a technical and programmatic evaluation from among 74 submissions. While semifinalists will each receive $50,000 to develop their concepts into prototypes, anyone can submit a prototype to compete in the second phase of the challenge to win up to $100,000.
Scientists Discover How Chlamydia Bacteria Take Control
March 28th 2017When Chlamydia trachomatis infects a human cell, it faces a huge challenge: It must prevent the cell from triggering programmed cell death to prevent the bacteria from replicating and spreading throughout the body. Since numerous metabolic processes are either missing or fragmented in the pathogen, it is reliant on the host cell to supply the vital nutrients on a permanent basis.
'Flying Syringes' Could Detect Emerging Infectious Diseases
March 28th 2017Blood-sucking flies can act as 'flying syringes' to detect emerging infectious diseases in wild animals before they spread to humans, according to research published in the journal eLife. The discovery has significant implications for our ability to control the global outbreak of new and re-emerging infections such as the Ebola and Zika viruses.
Compliance With the Manufacturer's Instructions for Use
March 28th 2017Q: Recently, I refused to process a device based on the following manufacturer’s instructions provided: “The xxx parts are made of durable aluminum and can be cleaned with ultrasound and any cleaning agents. Any standard sterilization technique is acceptable. There are no moving parts to maintain.” I contacted the company to alert them the instructions for use (IFUs) were insufficient. The company replied that “reprocessing is a different concept from cleaning and sterilizing a simple instrument for reuse.” They stated that the particular instrument in question “is a simple "instrument" like a retractor or a mallet. These instruments are reused; do not have critical "parts" that need to be retested between uses. They need to be cleaned and sterilized. It is a simple device with no moving parts or cavities or other complicating factors. How does one handle this?
Researchers Crack Structure of Key Protein in Zika Virus
March 27th 2017Zika virus (ZIKV), which causes Zika virus disease, is spread to people primarily through the bite of an infected Aedes aegypti or Aedes albopictus mosquito. An infected pregnant woman can pass ZIKV to her fetus during pregnancy or around the time of birth. Sex is yet another way for infected persons to transmit ZIKV to others.
NUS Pharmacy Team Develops Calculator to Predict Risk of Early Hospital Readmission
March 27th 2017Patients who are discharged after a hospital stay will want to stay away from the hospital for as long as possible. However, in Singapore, approximately 15 percent of patients who have been discharged from hospitals will succumb to a readmission within 30 days, while globally, readmission rates within 30 days can be as high as 20 percent.
