Bridging tumor moats with potent drug delivery particles

Bridging tumor moats with potent drug delivery particles
Despite herculean efforts, cancer remains a formidable disease, with each malignant subtype responding differently to therapeutics. One hurdle specific to treating solid tumors is a protective layer called an extracellular matrix that can prevent chemotherapeutic agents from penetrating the tumor’s core. Scientists now report results in ACS’ Chemistry of Materials showing that, by cloaking anti-cancer drugs in a specially designed particle, they could target and destroy tumor cells deep inside a malignant mass in vitro.

The only video you’ll ever need to watch about gluten

WASHINGTON — Bakers on TV are always talking about whether their goodies have enough gluten. But the masses on Twitter act like gluten is some kind of monster hiding in your bread. So what gives? Is gluten good, or is it bad? This video from Reactions explains what gluten is, how it leads to tasty bread, and the health risks it holds for certain groups of people:

Company-sponsored CRISPR clinical trials set to start in 2018

Company-sponsored CRISPR clinical trials set to start in 2018
This year could be a defining one for CRISPR, the gene editing technique, which has been hailed as an important breakthrough in laboratory research. That’s because the first company-sponsored clinical studies will be conducted to see if it can help treat diseases in humans, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

My Scottish Father Would Roll Over in His Grave

My Scottish Father Would Roll Over in His Grave,
Most people know that obesity is a health issue. But how many know that it’s responsible for 95 percent of Type 2 diabetes? Or that 50 percent of diabetes patients die of heart attack? How many readers know how obesity affects surgery? And what would make my father roll over in his grave?

For 60 years I’ve seen obesity in children and adults increasing in North America and most of the world. It’s tragic that few people fully understand how much this epidemic affects their lives and what it’s costing society.

What Did You Learn From Me in 2017?

What Did You Learn From Me in 2017?
I hope my columns during 2017 have helped readers live longer and healthier. So which of the following are true or false?

  1. There’s evidence that regular activity lowers the risk of dementia. Also a suggestion that high daily doses of vitamin C can decrease the risk of Alzheimer’s disease.
  2. Researchers at The Harvard Medical School report the magical ingredient in fish to decrease the risk of heart disease is omega-3 fatty acids, which like Aspirin, add oil to the blood making it less likely to clot.
  3. The survival rate of cancer of the prostate has little to do with the type of treatment. Rather, it’s related to the biological nature of the malignancy. Some cancers are pussy cats, others raging tigers.

Harnessing sperm to treat gynecological diseases

Harnessing sperm to treat gynecological diseases
Delivering drugs specifically to cancer cells is one approach researchers are taking to minimize treatment side effects. Stem cells, bacteria and other carriers have been tested as tiny delivery vehicles. Now a new potential drug carrier to treat gynecological conditions has joined the fleet: sperm. Scientists report in the journal ACS Nano that they have exploited the swimming power of sperm to ferry a cancer drug directly to a cervical tumor in lab tests.

Blueberry vinegar improves memory in mice with amnesia

Blueberry vinegar improves memory in mice with amnesia
Dementia affects millions of people worldwide, robbing them of their ability to think, remember and live as they once did. In the search for new ways to fight cognitive decline, scientists report in ACS’ Journal of Agricultural and Food Chemistry that blueberry vinegar might offer some help. They found that the fermented product could restore cognitive function in mice.

Want a Pet? The Risk and Benefit

Want a Pet? The Risk and Benefit
Who doesn’t love the pet who lavishes unconditional affection through thick and thin? President Harry Truman, while coping with the lonely responsibilities of his job, remarked, “If you want a friend in Washington, buy a dog!” But there are risks and responsibilities in pet ownership. It’s a matter worth considering since about 57 percent of North Americans own a pet.

In the Canadian Medical Association Journal, Dr. Paul Cherniack and Angela Cherniack discuss some of the infectious risks in owning pets. Yet it’s amazing that, in spite of these risks, studies indicate doctors rarely ask patients about pet ownership of dogs, cats, rabbits, birds, reptiles and rodents.

So what are the main infections to consider? Cats are most likely to infect humans with bacterial disease called Bartonella, usually triggered by a scratch from claws infected with feces of fleas, or a flea bite. This causes the swelling of lymph nodes. In severe cases, this can result in inflammation of the heart, and nerves and cause lesions on the liver, spleen and skin.

We need More Love in the Christmas Stocking

We need More Love in the Christmas Stocking
What does this world need more than anything else this Christmas? It needs gifts of love, empathy, civility, less hatred, less poverty and less environmental pollution, destruction of guns and missiles before it becomes too late. It needs a mindful civilization that cares about every human being. And it must start with individual families and end with politicians throughout the world who control nuclear weapons.     

I enjoy the festivities of the Christmas season. For a short time the world looks less likely to blow itself up. But for people who’ve lost loved ones it’s a grim, lonely time. A Christmas surrounded by possessions, but without family and friends who care is the setting for depression.
