Pyrazinamide (PZA) - a frontline tuberculosis (TB) drug - kills dormant persister bacteria and plays a critical role in shortening TB therapy. PZA is used for treating both drug susceptible and multi-drug resistant TB (MDR-TB) but resistance to PZA occurs frequently and can compromise treatment...
i have a circuit with 2 resistors in series (15kohms and the other is only 40ohms) then 3 resistors in parralell and they are (25kohms, 50kohms and 150kohms) the voltage is 24v and thats all the information that is given.
i have to work out the: total resistance of the circuit, the total current...

Re-routing anti-cancer drugs to the "power plants" that make energy to keep cells alive is a promising but long-neglected approach to preventing emergence of the drug-resistant forms of cancer - source of a serious medical problem, scientists are reporting. That's the conclusion of a new study...
A study that aimed to understand how the cancer drug everolimus helps overcome the resistance breast cancers can develop to trastuzumab has left researchers contemplating a puzzle. The study showed a statistically non-significant benefit in clinical response rates for some patients with early...
A study presented at the AACR Annual Meeting 2013 indicates that a DNA blood test using Inostics' BEAMing Digital PCR can detect more mutations associated with secondary drug resistance in GIST patients than testing conventional biopsies. Therapies targeted to specific cancer-causing mutations...
The experimental drug selumetinib may allow some patients with advanced thyroid cancer to overcome resistance to radioiodine (RAI), the most effective therapy for the disease, according to new research from Memorial Sloan-Kettering Cancer Center. Published in the February 14 issue of the New...
In their natural environment bacteria develop by forming communities of micro-organisms called biofilms that afford them greater resistance.These biofilms on farms and premises where food is processed lead to considerable economic losses besides being a potential source of contamination and...
Patients with HER2-positive breast cancer being treated with anti-HER2 therapy may be able to prevent or delay resistance to the therapy with the addition of a phosphatidylinositol-3 kinase inhibitor to their treatment regimens. The data, published in Cancer Research, a journal of the American...
The BBC has a somewhat alarmist new report on the growing strains of antibiotic resistant bacteria in the world. According to the chief medical officer for England, the rise of antibiotic resistant strains is comparable to the threat of global warming. More »

Aerobic training is the best mode of exercise for burning fat, according to Duke researchers who compared aerobic training, resistance training, and a combination of the two. The study, which appears in the Journal of Applied Physiology, is the largest randomized trial to analyze changes in...
Assuming I am doing this workout with a proper diet and cycling at a moderate to high heart rate, is this sufficient for fat loss?

Political measures to reduce antimicrobial resistance in Europe and the UK are in danger of becoming kneejerk reactions that are not based on sound science, the British Veterinary Association (BVA) has warned ahead of European Antibiotic Awareness Day (18 November). The BVA has told vets that...
Antibiotic resistance remains a major threat to public health around the world, and for the large part, the cause is misuse of antibiotics, says the European Centre for Disease Prevention and Control (ECDC). The ECDC put out the message in a statement released on Sunday to coincide with the...
PLEASE HELP? Explain the definition of following:
a) Current in terms of rate of flow of mobile charge carrier
b) Conductance and resistance in relation to density of mobile charge carrier.
Blocking the action of a particular protein in our skin could improve the treatment of skin cancers, according to a study published in Oncogene by Philippe Roux, a researcher at the University of Montreal's Institute for Research in Immunology and Cancer (IRIC). "Our findings reveal part of the...
New research led by the University of Manchester in the UK has found a biomarker or molecular "flag" in women with breast cancer who do not repond, or who have become resistant, to treatment with the hormone drug tamoxifen. The researchers say their discovery will help doctors predict which...
With their excellent sensitivity and specificity, the use of these extremely efficient tests on a world-wide scale would allow us to adapt antibiotic treatments to the individual's needs and to be more successful in controlling antibiotic resistance, particularly in hospitals. These works were...
As a result of concerns about antibiotic resistance, doctors in the United States are increasingly prescribing newer, more costly and more powerful antibiotics to treat urinary tract infections, one of the most common illnesses in women. New research at Oregon State University suggests that the...
