From 230,000 patients to extinct in 15 years: pathology and new drugs key to defeating hepatitis C

An estimated 230,000 Australians have chronic hepatitis C, and a quarter of cases are undiagnosed.

Hepatitis C inflames the liver and unlike the A and B viruses there is no vaccine available. Pathology is important for diagnosing the virus.

Many people with hepatitis C may not experience symptoms, but left untreated the disease can cause cirrhosis (scarring of the liver), which in a small number of cases can lead to liver cancer.

Sauna: What are the Health Benefits?

Saunas have been used for hundreds of years and still continue to be popular today. Many people enjoy sitting in a sauna to unwind and relax.

Spending time in a sauna can feel good, and there may be additional health benefits to be had beyond relaxation.

Many people enjoy relaxing and unwinding in a sauna. Steam rooms involve high humidity and
moist heat as opposed to the dry heat of traditional Finnish saunas. It is vital to drink plenty of
water after using a sauna.

A Lab Manager's Guide to Getting Ahead

Being motivated and showing resourcefulness are what separate a star from the pack

Hard Work, Resourcefulness, and Great Mentors Required

When Lydia Coleman was 25 years old and worked as a staff member in a laboratory, before a surveyor’s visit she asked her then-boss whether managers had done anything in advance to prepare for the survey and had thought about what kinds of questions might arise. Coleman’s boss immediately realized that her employee’s questions showed initiative and enthusiasm for making the workplace run more smoothly, and she expressed her opinion of what a good idea that was. Six years later, Coleman had showed so much enterprise and learned enough to apply for and land a laboratory supervisor’s position, and for the past 35 years she has been either a manager or a director in the health care laboratory industry.

Transfusion-Related Thrombocytopenia In a Chronic Renal Failure Patient

Hemostasis is a process to stop bleeding that requires coordinated activities of vascular, platelet, and plasma factors. Under normal conditions, blood vessel injury will trigger endothelial cells to secrete factors that promote adhesion and activation of platelets. First, platelets bind to von Willebrand’s factor (vWF) secreted by endothelial cells through vWF receptors. Attached platelets then undergo degranulation and release factors such as serotonin, which causes vascular constriction. Activated platelets also release other mediators to attract additional platelets for aggregation at the injured sites.

Swarms of Magnetic Bacteria Could be Used to Deliver Drugs to Tumors

One of the biggest challenges in cancer therapy is being able to sufficiently deliver chemotherapy drugs to tumors without exposing healthy tissues to their toxic effects.

Researchers funded in part by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have recently shown that magnetic bacteria are a promising vehicle for more efficiently delivering tumor-fighting drugs. They reported their results in the August 2016 issue of Nature Nanotechnology.

What Do We Really Need To Know About Platelets And The Laboratory?

What is a platelet? The anatomic definition of a platelet is well established: According to MedicineNet.com, it is “an irregular, disc-shaped element in the blood that assists in blood clotting. During normal blood clotting, the platelets clump together (aggregate). Although platelets are often classed as blood cells, they are actually fragments of large bone marrow cells called megakaryocytes.” This definition, however, does not do justice to our rapidly expanding understanding of the platelet’s roles, functions, and laboratory applications.

What the numbers say

Laboratories with the ability to detect platelet function defects still tend to focus on identifying the two percent of the population that have heritable platelet function defects and von Willebrand Disease.

Curiosity About Cigarettes, Cigars Falling among Students

Fewer middle and high school students in the United States have ever used or are curious about using cigarettes or cigars, according to new research published in the journal Preventing Chronic Disease.

However, the study - conducted by researchers from the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) - identified no change in the percentage of American students who have ever used or are curious about smokeless tobacco.

Research Antibody Reproducibility

It’s All About Validation

The reproducibility of scientific studies has become a major issue, leading to a lack of trust in scientific results from the academic and pharmaceutical research communities. While issues around reproducibility have been discussed for years, calls for action have been infrequent and half-hearted. Beginning in about 2012, a number of articles, letters, and editorials started appearing in Nature, Science and other publications, with some going so far as to call this a “reproducibility crisis.”

Cancer: Shutting Down Fat Synthesis In Cancer Cells Stunts Tumor Growth

Tumors have a voracious appetite for fat and rely on hastened fat synthesis in cancer cells to satisfy their need. Now, a new study shows it is possible to use drugs to shut down fat synthesis in cancer cells to stunt tumor growth without harming healthy cells.

A report on the study is published in the journal Nature Medicine.

The discovery - by researchers at the Salk Institute in La Jolla, CA, and collaborators - represents a new frontier in the search for targeted treatments against cancer, a leading cause of disease and premature death worldwide.

This Type Of Vitamin E Could Predict Your Risk For Alzheimer's—And You're Probably Not Getting Enough Of It

Vitamin E is essential for normal neurological function, according to a 2013 Journal of Internal Medicine study, which found that low levels of some types of the vitamin could help predict your risk for Alzheimer's disease. Looking to take back control of your health? 

Some types? That's right: There are different types of vitamin E. In fact, there are 8 varieties or "isoforms" of E, and research suggests your brain needs all of them for optimal health and function.
