The Healing Power of Yogurt

by Sara Klink in Promega Connections

There has been much made of probiotics regulating digestive health in the news and repeatedly hawked by people sharing the benefits of yogurt with special bacteria that will change your life. I was advised by my mother that when I was taking antibiotics, eating yogurt would help counteract some of the negative consequences of oral [...]... Read more »

It’s a Jungle in There: ENCODE and the Redefinition of the Gene

by Isobel Maciver in Promega Connections

September 5th saw the simultaneous publication of more than 30 papers in Nature, Genome Research and Genome Biology detailing the findings of the ENCODE project (Encyclopedia of DNA Elements)—an international collaborative research effort involving the work of more than 400 scientists in 32 groups over the last eight years. Building on the work of the [...]... Read more »

Don’t Wear Your Retro Polyester Pantsuit into the Ecuadorian Rainforest (or a new player in the bioremediation of plastics)

by Promega Corporation in Promega Connections

Plastics are really cool. They keep you from having slippery glass shampoo bottles in the shower that can drop and break. They have allowed us to get rid of glass thermoses from student’s lunches. They are lightweight, making shipping and packaging of goods cheaper and lighter, and often, safer. The plastics industry, according to the [...]... Read more »

Molecular Connections Between Sleep Deprivation and Inflammation

by Isobel Maciver in Promega Connections

Anyone who has travelled across time zones knows how unpleasant it is when the regular rhythm of your biological clock is disrupted. Jetlag results when the body’s internal clock, or circadian rhythm is out of sync with external cues for “day and “night”, resulting in insomnia, extreme tiredness, difficulty concentrating and various other unpleasant symptoms. [...]... Read more »

The Redhead’s Natural Defense Against Melanoma

by Terri Sundquist in Promega Connections

It seems fitting that, as I write this blog entry, I am soaking up a bit of sun on a dock on a small northern Wisconsin lake. I’ve deployed many of my normal defenses against the sun’s harmful rays, including a big floppy hat and plenty of sunscreen. Recently, I learned that, as a redhead, [...]... Read more »

Protein Profiling of a Lung Infection in a 500-Year-Old Mummy

by Sara Klink in Promega Connections

I am fascinated by all the ways that scientists are taking sensitive techniques and using them to look into our past. For example, scientists constructed the entire genome of Yersinia pestis, the caustive agent of the Black Death, from teeth and bone samples of plague victims from the 14th century. Without methods like polymerase chain [...]... Read more »

Hypomethylation in the Hippocampus: Can Age-Related Cognitive Decline in Mice Be Reversed by the Activity of One Gene?

by Promega Corporation in Promega Connections

Buried in the middle of the August issue of Nature Neuroscience is an article (1) by Oliveira, Hemstedt and Bading that caught my eye. It isn’t often that I see a paper about gene rescue in a neuroscience journal, especially in a study about cognitive decline. I looked for a News and Views summary of [...]... Read more »

Curcumin Moderates the Health Effects of Diesel Exhaust

by Sara Klink in Promega Connections

The majority of the ground transporation in the United States runs on diesel fuel. It powers most of the fleet of large vehicles that travel around Wisconsin and across country moving products and people. My family uses diesel fuel in all the large tractors that plant and harvest the 1,200+ acres of crops on the [...]... Read more »

Methylation of Your Genome Decreases as You Age

by Sara Klink in Promega Connections

If asked what are the differences between a grandfather and his newborn granddaughter, I would reply with the obvious ones: size (the grandfather is larger than his granddaughter), condition of the skin (babies have soft, smooth skin and elders have age spots and wrinkles) and life expectancy. Other visual cues may seem more similar than [...]... Read more »

Awwww, Ain’t That Sweet?

by Amy Hendricksen in Promega Connections

There are many things that I love about summer…being out on the water,  puttering around in my garden, and local festivals top the list.  But the best, the absolute best, is the produce.  I could (and have!) spent hours at the farmer’s market, admiring the myriad of colors and varietals laid out under crisp white [...]...

The Fat You Wish You Had

by Kari Kenefick in Promega Connections

Brown fat, white fat…isn’t all adipose tissue the same? Previously thought of as the domain of infants and hibernating bears, brown adipose tissue has been identified in the adult human body as well. Two papers that appeared in The New England Journal of Medicine in 2009 reported that adult humans have brown fat, found in small [...]... Read more »

Forgot Something? Maybe Your Diet, not Your Age, is to Blame

by Terri Sundquist in Promega Connections

Have trouble finding your car keys this morning because you forgot where you left them? Or maybe you can’t remember the name of the new person who just joined the department down the hall? Before you blame age for your faulty memory, take a look at your diet. New research suggests that low levels of [...]... Read more »

Autophagy: The Intersection of Vitamin D, HIV and Tuberculosis

by Sara Klink in Promega Connections

With the warmer season in full swing in Wisconsin, the grass needs mowing and the weeds need pulling. As a consequence, I am outside in the sun, synthesizing Vitamin D (and watching my freckles multiply). The benefits of this vitamin have been discussed in the news (e.g., may help prevent cancer, maintains a healthy working [...]... Read more »

Tracking the Progression of Plague Using Bioluminescence

by Sara Klink in Promega Connections

Sequencing Yersinia pestis, the bacterium that caused the Black Plague in Europe during 1348–50, is an amazing accomplishment. Y. pestis infection still occurs sporatically and causes fatalities despite the Age of Antibiotics. Even with animal models, there are questions remaining about the progression of infection. Nham et al. used in vivo imaging to examine the [...]... Read more »

Making Antibiotics More Effective Against Multidrug-Resistant Bacteria

by Sara Klink in Promega Connections

The Age of Antibiotics may prove to be our downfall as more and more microbes find a way around the compounds we use to treat bacterial infections. A potential antibiotic is no more tested, synthesized, clinically tested and approved than a bacterial strain finds a way to circumvent its action and shares this solution with [...]... Read more »

A Food for Happiness? Go Fish

by Kari Kenefick in Promega Connections

We’ve heard that omega-3 fatty acids, such as those from various fish sources, have important anti-inflammatory, as well as cardiac health benefits. In fact, WebMD has an Omega-3 Fatty Acid Fact Sheet with so much positive health information that you may add “Buy wild-caught salmon” to your list of things to do on the way home [...]...

The Daughters of King Tutankhamun

by Terri Sundquist in Promega Connections

The pharaoh Tutankhamun ruled ancient Egypt during the 18th dynasty of the New Kingdom (circa 1550–1295 BC), one of the most powerful royal houses in ancient Egypt. Although he sat on the throne for only 9 years and died at the young age of 19, he is one of the most well known pharaohs, due [...]... Read more »

Could the Next Chemotherapy be Derived from a Weed?

by Sara Klink in Promega Connections

As much as I may complain about weeds, one that I enjoy (in moderation and not among my vegetables) is dandelions. The bright yellow flowers herald spring, and the seed puffballs, while not as visually interesting, offer entertainment as I watch birds landing on the shaft, bending it and eating the seeds. When I am [...]... Read more »
