RoundUp - 1st Week of November 2023






The Mediterranean Diet Improves Your Body’s Insulin Response



The more closely you adhere to the Mediterranean diet, the more effectively your body utilizes insulin.  This is critical for type 2 diabetics who must make the most of the insulin they do produce.  This effect of the Mediterranean diet consisting of fish, whole grains, nuts, seeds, olive oil, fruits, and vegetables was studied in a group of 62 overweight middle-aged participants by Italian public health researchers.


The subjects were divided into high and low Med Diet adherence groups.  The data revealed that high diet adherence was associated with high sensitivity and low resistance to insulin.  This evidence offers continued support for eating a Mediterranean diet, particularly for diabetics.

Newly Discovered: Fetal Fentanyl Syndrome



Just reported is a new syndrome that results from the exposure of a developing  fetus to the opioid fentanyl.  Geneticists at Delaware’s Nemours Children’s Hospital have studied a group of 6 patients with short stature, small heads, unusual facial features, cleft palate, deformed hands and feet, and genital abnormalities.    The study authors also reports 4 additional cases from other institutions.  


Mirroring the fetal alcohol syndrome which also presents with slow physical growth, small heads, brain abnormalities, distinctive facial features, and limb deformities, fetal fentanyl syndrome  results from metabolic aberrations during gestation that result from intentional or accidental exposure to this recreational narcotic. Genetic studies on these infants failed to detect DNA abnormalities that explain these unique features so Fetal Fentanyl Syndrome is the result of the drug’s chemical toxicity.



Abuse of fentanyl, a synthetic opioid 50-100 times more potent than morphine, is the driver for overdose deaths that have surged some 22 fold over a recent 8 year period.  Now we know that exposure to this dangerous drug by pregnant women also results in extreme toxicity to the developing fetus.

Eyes Predict Depression Relief Using Magnetic Brain Therapy



Patients suffering from depression who evidenced greater eye pupillary constriction after exposure to light enjoyed better relief of their depressive symptoms following treatment with transcranial magnetic stimulation or TMS.  UCLA neuroscientists report this finding following their study of 51 patients with major depressive disorders who were undergoing daily TMS.


Their data reveal a direct correlation between the strength of the so-called pupillary light reflex and the percentage of relief from depressive symptoms after magnetic brain stimulation.


Transcranial magnetic stimulation is a non-invasive technique during which focused magnetic fields bathe portions of the brain.  Looking to predict which patients will benefit most from this therapy, clinicians have studied various signals from the human involuntary nervous system including the variability of heart rate and the pupillary light reflex.  These nervous system fluctuations occur involuntarily as responses to stress, fear, and danger.  The pupillary light reflex is easily triggered, occurs rapidly, and is easily measured making it an ideal predictive test.

A Sleepless Night Could Lift Your Spirits



An isolated night with little or no sleep seems to produce a “punch-drunk” state with accompanying mood elevation that lasts for days afterward.  Northwestern University neurobiologists report this seemingly paradoxical effect after reproducing this common human situation in a preclinical mouse model.


After inducing acute sleep deprivation in the animals, analysis shows increased brain dopamine release and enhanced synaptic plasticity.  This biochemical brain rewiring is associated with a persistent happier mood which the animals evidence by hyperactivity and hypersexuality.


The researchers remind us that chronic sleep deprivation is harmful so pulling repeated all nighters is not a strategy for treating a persistent gloomy outlook let alone clinical depression.  On the other hand, the effects of an isolated sleepless night may represent the persistence of a phenomenon whereby animals and prehistoric humans reacted with a predator threat with persisting vigilance and the ability to fight or quickly flee.

Smartphone Use Associated With Diminishing Sperm Numbers



Men on their phones more than 20 times a day have a 21% higher risk of a subnormal absolute sperm count and a 30% higher risk of having a low sperm concentration.  Swiss epidemiologists report these findings following their study of 2886 men 18 to 22 years of age.


All participants submitted semen samples and completed a health and lifestyle questionnaire including their cellphone use habits.  In addition to the worrisome sperm count and concentration findings, the data did show some positives: sperm shape and motility were unaffected by cellphone use.


Among the one in every six couples who experience infertility, the male partner is found be the source of conception problems in about half.  Other studies have reported a significant overall decline in sperm quality over the past decades.  This has been attributed rising rates of obesity, alcohol consumption, stress, and toxins in our environment and food.  In the case of cellphones, studies have shown that the electromagnetic fields the phones produce reduce sperm cell production and trigger sperm cell death.


So…. Guys.  Maybe give your cell phones a break.  At least use them with earphones and keep them as far as possible from your body when they are actively transmitting radio signals.

Anger Can Power Your Best Efforts



Happiness is contentment, but emotion and even angry emotion is what gets things done.  Texas A&M psychologists report this somewhat surprising finding following their completion of six studies involving 1,000 plus participants and their analysis of survey responses from more than 1400 persons.


In each of the studies, an angry emotion was elicited in various ways including exposure to negative illustrations, generation of levels of frustration, and reaction to political situations.  Performance was measured when participants were faced with a variety of challenges including puzzles, performing on a Nintendo Wii, responding quickly in a computer game, or by voting behavior as quantified in survey results.


The trend across the 6 studies was that the participants performed better when in the angry state.  As examples, anger increased the numbers of puzzles solved and the reaction times in the computer games.


Anger and associated frustration can be a powerful motivator.  As those most successful in science, business, and novel writing will tell you, the path to success is often facilitated by multiple failures along the way.  In addition to showing what doesn’t work, these misfires also create stronger emotions that no doubt fuel efforts which eventually pay off.

Using Magnets To Trigger Brain Activity



Bioengineers at Rice University have developed a novel metamaterial that can generate a steady microvolt electrical current when its exposed to an alternating magnetic field.  Implanting this material in select portions of the brain would permit clinicians to stimulate specific neural centers by exposing a patient to a focused magnetic field.  The device requires no internal power source.  So far, the researchers have used the material to wirelessly trigger nerve signals in the peripheral nerves of experimental animals.  With refinement, the technique could come to the clinic…..Someday soon.

Microfluidic Test System Allows Multi-Organ Testing



A literal “body on a chip” permits the testing of drugs and other biologics on multiple organs simultaneously.  Developed at Northwestern University, the so-called Lattice device permits the simultaneous testing of potential therapeutics on up to 8 different organ systems.  The organ tissue samples or artificially-generated organoids are placed in separate wells, and the medications to be tested flow into each well via micro-channels.  Another function of Lattice permits testing the effects of one organ on another or others.  For example, a hormone-producing organ in one well is bathed in nutrient media that picks up the hormones and carries them to other wells containing other organs.  It’s a brave new world, and it’s coming……Someday soon.

AI-Driven ECG Interpretation Detects Heart Disease Earlier



The Mayo Clinic and a biotech spinoff Anuman have developed 3 separate ECG-AI models that together can pinpoint hearts at risk for potentially devastating attacks some 3 years earlier.  These independent AI algorithms look at coronary arterial calcium deposits, coronary arterial blockages, and left ventricular wall movement abnormalities.  To develop these models, the researchers retrospectively analyzed the electronic medical records of more than 7 million patients from across the US.  Anumana specializes in the use of AI to develop enhanced interpretive models for analysis of ECGs and ECHO cardiograms that not only predict coronary artery-related disease but also arrhythmias, degenerative heart disease, valvular disease, and pulmonary hypertension.

Mini-Refrigerator-Sized Bioreactor For Growing Immune Cells



Bioengineeers at the Washington State University have developed a relatively compact machine for rapidly growing the T killer cells employed by many immunotherapeutic regimens to destroy cancer cells.  Their system utilizes centrifugal flow techniques to accelerate immune cell propagation to a speed 30% faster than most current techniques.  Since one popular and effective cancer immuotherapy, the CAR-T strategy used for treating leukemias, requires as many as 250 million modified T-cells for each infusion, rapid amplification of T cell numbers is mandatory.  The researchers are hard at work modifying this initial bioreactor in order to produce greater numbers of cells even faster.  Patents are pending to facilitate commercialization.
