Weird stuff found in recreational drugs: Cocaine edition
by Rosin Cerate in Rosin Cerate
This is the fifth and final post in a series on strange substances accidentally or intentionally added to street drugs. When you're done here, check out the posts on alcohol, meth, opioids, and pot/LSD.If a drug is being sold illegally, chances are its sellers have added crap to it in order to make more money. Cocaine is no exception to this deception. Substances added to nose candy because they resemble the drug but otherwise don't mimic or influence its effects include talc powder, flour, corn........

The Genetic Architecture of Complex Disease
by Daniel Koboldt in Massgenomics
It’s no secret that while genome-wide association studies (GWAS) have implicated thousands of genetic loci in human phenotypes, the variants uncovered collectively explain only a fraction of the observed variance between individuals. The reasons for this “missing heritability” are a subject of vigorous debate in the scientific community. One possible explanation is that rare (low-frequency) variants […]... Read more »

This is the fourth post in a series on strange substances accidentally or intentionally added to street drugs. When you're done here, check out the posts on alcohol, meth, opioids, and cocaine.In the autumn of 2007, hospitals near Leipzig, Germany admitted 29 people after they inadvertently smoked weed contaminated with lead. Yep, some dealer or grower decided it was a good idea to drop a bunch of small lead particles into the marijuana they were selling, presumably to increase its weight (lead ........ Read more »

by Rosin Cerate in Rosin Cerate
This is the third post in a series on strange substances accidentally or intentionally added to street drugs. When you're done here, check out the posts on alcohol and meth.Opioids are drugs that affect the human body by binding to a group of related proteins conveniently known as opioid receptors. By connecting to these receptors in a certain manner, they convince receptor-bearing cells in the brain, spinal cord, and intestine to do useful things like reduce the sensation of pain (while making ........

Weird stuff found in recreational drugs: Meth edition
by Rosin Cerate in Rosin Cerate
As Breaking Bad has taught us, the clandestine manufacture of methamphetamine is a very dangerous undertaking. It involves the use of many harmful substances, which depending on the synthesis method include highly corrosive acids and bases, cancer-causing benzene, brain-damaging mercury and lead, jaw-wrecking phosphorus, and blood-breaking sodium cyanide. Blending these various substances together can produce noxious fumes, making gas masks and chemical suits a necessity if you want to avoid get........ Read more »

Seeing Through the Skin
by Aurametrix team in Olfactics and Diagnostics
Human skin emits light (albeit the glow is extremely weak) and a wide variety of small molecules that may be sometimes "sniffed" by dogs or even other humans. These chemicals tell a story about our health and wellness, things we eat and drink, touch and breathe. Mosquitoes use such emissions to assess our "attractiveness" from indicators such as Indoles (unpleasantly smelling but healthy "inner soil" biomarker) or carbon dioxide (amount of which correlates with the size of the person........

Weird stuff found in recreational drugs: Alcohol edition
by Rosin Cerate in Rosin Cerate
Today's post is the first in a series I'm going to write about extra ingredients found in illicit recreational drugs. One of the major issues with street drugs is their manufacture and distribution is often poorly regulated. This means they can accidentally become contaminated with all sorts of toxic substances during production. Additionally, a wide range of chemical compounds, some of them harmful, may be intentionally added to dilute a drug (like a bar watering down their drinks to make more ........ Read more »

Friday the 13th
by Aurametrix team in Environmental health
Our health depends on a multitude of environmental factors, day in and day out. And today is a special day - Friday the 13th. How should you feel on this day? Friday the 13th is one of the most feared dates, associated with bad luck in the West. And it is taken cautiously even in cultures that do not fear the 13th - for example, among Chinese mothers avoiding delivering their babies on the 13th. But science says that those born on the 13th and even those born on Friday the 13th are not in ........ Read more »

How to Solve Homicide Crimes
by William Yates, M.D. in Brain Posts
Homicide rates in the U.S. represent a significant public health challenge. Homicide is a top ten leading cause of death in many groups in the U.S.One method to reduce homicide rates is to quickly identify and arrest individuals who have committed homicide. This is due to the fact that individuals committing homicide have a high rate of future homicide.A recent study from Michigan State University and Indiana University examined characteristics of U.S. police departments that have high rates of ........

Left Kidney Donation Preference
by Cristy at Living Donor 101 in Living Donors Are People Too
During living kidney donation, the left kidney is most often taken because the right kidney rests behind the liver. In simple terms, it’s easier to access the left kidney. But it also appears that the left kidney has a longer renal vessel than the right (an important consideration that is rarely, if ever, mentioned during …

"The Biggest Loser": Long-term Effects
by William Yates, M.D. in Brain Posts
Yesterday I posted a link to a New York Times article that posted a summary outcome in fourteen participants in TV's "The Biggest Loser" show.The study found a trend towards post-show weight gain for 13/14 of the participants.Four participants actually gained so much weight that after six years they weighed more than before participating in the show.A key finding from the study was this weight gain could be explained by a metabolic response resulting in up to 800 calories less burned daily ........

Kidney Donors Suffer More Pain
by Cristy at Living Donor 101 in Living Donors Are People Too
The authors compared 30 living kidney donors with 30 other individuals who underwent a nephrectomy (kidney removal) because of a tumor. They found that living kidney donors experienced more pain than the comparison group, and they asked for (and were given) more pain medications. Wang, J., Fu, Y., Yuan, T., & Wang, N. (2015).

Psychiatric Complications in Living Liver Donors

The authors studied 142 donors who underwent live-donor liver transplantation at Nagoya University Hospital between April 2004 and July 2014. None of the living donors had pre-existing psychological complaints prior to donation. 4.2% developed psychiatric complaints after donation, including major depressive disorder, panic disorder, conversion disorder, and substance use disorder. (my emphasis) “all donors received …

Liver Regeneration in Living Donors
by Cristy at Living Donor 101 in Living Donors Are People Too
The authors examined the liver function and liver volume of 91 right liver lobe donors. Within a year of donating, 96% had regained full liver function but only 85% had full pre-donation liver volume. Unfortunately, these results say nothing about the long term risk of scarring (cirrhosis) or otherwise. Duclos J, Bhangui P, …
