Hairy Boy Bets on Laser Treatment for Cure

..." Naik told IANS. "We will of course do a hormonal assay before deciding the course of action." Despite his unusual problem, Prithviraj has been doing consistently well in his studies. When the father saw that the lanugo hair, as the condition is called in medical jargon, he took his son to a few skin ...

Flash-heating Inactivates HIV in Breast Milk: Study

...s note that they used a reverse transcriptase (RT) assay to test for an enzyme produced by viable HIV since traditional tests for HIV do not distinguish between dead and live viruses. The RT test, however, cannot detect HIV within cells, but preliminary data suggest that flash-heat inactivates cell-associa...

Resistance Already Emerging in First Months of Treatment Despite Viral Load Decline

...03N and M184V (reverse transcriptase), using a PCR assay designed to detect the three specific mutations.The specificity of the assay allowed the detection of mutant virus populations if they comprised no more than 0.01-0.2% of the to...

Nanoparticles can Damage DNA, Increase Cancer Risk

...using the alkaline single-cell gel electrophoresis assay (Comet assay) to quantify breaks in single and double stranded DNA. The team chose these particular nanoparticle types because they are commonly used commercially – in electronics, textiles and sporting goods – and easy to work with in the laboratory...

Research Improves Kidney Transplant Chances for Sensitized Patients

...hile some transplant centers use these same single assay tests to identify HLA antibodies, they don't incorporate the data into their cross-matching process. Prior to the Emory Algorithm, highly sensitized patients may have been at a disadvantage due to the time constraints in the organ donor process, whic...

Olive Leaf Juice Could Be Edible Oil Antioxidant

... they wrote. Using the thiobarbituric acid (TBA) assay to measure lipid oxidation, the researchers report that the 400 ppm level of olive polyphenolics exhibited almost the same antioxidant activity as 200 ppm BHT, while 800 ppm of olive polyphenolics was superior to the synthetic antioxidant. "Therefo...

FDA Clears Breast Cancer Specific Molecular Prognostic Test

...rst cleared in vitro diagnostic multivariate index assay (IVDMIA) device. Several months ago, FDA issued a draft guidance document concerning the need for these complex molecular tests to meet pre-market review and post-market device requirements even when the tests are developed and used by a single labor...

High Levels of Lipoprotein(a) in Women is Associated With Cardiovascular Risk

...ly high levels of lipoprotein(a), measured with an assay independent of apolipoprotein(a) isoform [a type of protein] size, were associated with increased cardiovascular disease risk, particularly in women with high LDL-C levels. This relationship existed independently of traditional risk markers, and CRP....

New Technique Identifies Unknown Genetic Mutations That Can Cause Cancer

...tudy of proteins. "We decided this more functional assay would get us to the disease-causing genes more rapidly," said Druker, who has been studying a group of cell-signalling proteins called tyrosine kinases for 20 years. Tyrosine kinases play a key role in many cancers. In healthy cells, they help form...

IMP3 the Novel Biomarker for Metastatic Cancer

...IMP3 testing is a simple, inexpensive and reliable assay that can be easily applied in routine clinical practice,’ explained Jiang. ‘If we can identify in those patients with early-stage disease the high potential to develop metastasis after surgery, we may be able to alter the course of therapy to improve...

Doubts About In UteroTransmission Of Senile Amyloidosis
