Having Second Thoughts: What Makes Us Who We Are Is Stunning as Well as Humbling
The first title’s dual meaning says it all. Meaning #1 is figurative: after reading this piece, some readers may have second thoughts about espousing a profound perspective on how we function; one likely never encountered before. Meaning #2 is quite literal: most of what we think we’ve deliberately and rationally produced of our own conscious reasoning is actually secondhand topping. That’s because most thinking begins in brain structures that entail the unconscious mind—the #2-mind whose functions we’re consciously unaware of and cannot access.
Our conscious mind is where our personal awareness of self, our â...

RWMA – Echo
RWMA – Echo
The term regional wall motion abnormality or RWMA can be used in any imaging which shows movements of the myocardial segments like echocardiography, cine cardiac magnetic resonance imaging, cine computed tomography and nuclear cardiology imaging. The left ventricular myocardium has been divided into 17 segments by the American Society of Echocardiography [1]. The true apex is a separate segment in this 17-segment nomenclature. In the previous 16 segment nomenclature, there is no separate true apical segment. True apical segment is beyond the left ventricular cavity towards the apex.

In this study, young adult mice were submitted to endurance exercise training and the function, differentiation, and metabolic characteristics of satellite cells were investigated in vivo and in vitro.
We found that injured muscles from endurance-exercised mice display improved regenerative capacity, demonstrated through higher densities of newly formed myofibres compared with controls (evidenced by an increase in embryonic myosin heavy chain expression), as well as lower inflammation (evidenced by quantifying CD68-marked macrophages), and reduced fibrosis. Enhanced myogenic function was accompanied by an increased ...

Implicating Striosomes in Age-Related Changes in Decision Making
The brain is very complex, and so the ways in which comparatively simple mechanisms of aging lead to alterations in cognitive function are also very complex. The research here picks up the trail of cause and effect relating to changes in approach-avoidance conflict, a part of decision making, a fair way down the line from first causes, as is the case for much of the work taking place on the aging of the brain. It is nonetheless always interesting to see specific age-related changes in complex traits connected to specific cells and their activity, even when the further connections to underlying mechanisms of aging remain ob...

In conclusion, the circulating antibody repertoire has increased binding to thousands of peptides in older donors, which can be represented as an immune age. Increased immune age is associated with autoimmune disease, acute inflammatory disease severity, and may be a broadly relevant biomarker of immune function in health, disease, and therapeutic intervention. The immune age has the potential for wide-spread use in clinical and consumer settings.

Towards a More Sensitive Blood Test for the Earlier Stages of Alzheimer's Disease
The onset of Alzheimer's disease is preceded by years of slowly growing levels of amyloid-β aggregates in the brain. There is an equilibrium between amyloid-β in the brain and amyloid-β in the bloodstream, and so the research community has worked towards blood tests that can determine who is at risk of developing the condition. This goal is complicated by the sensitivity required, given the low levels of amyloid-β in blood samples, but the results here suggest that this problem may be sufficiently well solved to proceed towards an widely used assay. While the failure of clinical trials testing amyloid-clearing immunoth...

Why p values can ’ t tell you what you need to know and what to do about it
Conclusions in the 2017 paper).
If you were willing to assume a 50:50 prior chance of there being a real effect the p = 0.005 would correspond to FPR50 = 0.034, which sounds satisfactory (from Table, above, or web calculator).
But if, for example, you are testing a hypothesis about teleportation or mind-reading or homeopathy then you probably wouldn’t be willing to give a prior of 50% to that being right before the experiment. If the prior probability of there being a real effect were 0.1, rather than 0.5, the Table above shows that observation of p = 0.005 would suggest, in my example, FPR = 0.24 an...

New online model identifies which men can have fewer biopsies on active surveillance
This study underscores the important research that is ongoing to help minimize invasive procedures for clinically localized prostate cancer in men who opt for active surveillance,” said Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of HarvardProstateKnowledge.org. Garnick added that in his practice, patients who have completely stable repeat biopsies for several years, as well as stable prostate MRI studies, are followed with a combination of “PSA values, physical exam, presence or absence of urinary symptoms, ...

Modified Simpson ’ s rule for LVEF
Modified Simpson’s rule for LVEF
Modified Simpson’s rule for LVEF
Modified Simpson’s rule for LVEF (left ventricular ejection fraction) is used not only in echocardiography, but also in cardiac magnetic resonance (CMR) imaging, left ventricular angiography and computed tomography (CT).
Basic assumption in Simpson’s rule is that the shape of the left ventricular cavity is a composite of a cylinder (from base to the level of the mitral valve), a truncated cone from mitral valve level to the level of the papillary muscles and a cone from there to the apex [1].
Volume of the cylinder: Am x L/3

A focal crinkling of the right ventricular outflow tract and subtricuspid regions on MRI in arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVD/C) has been called “accordion sign” [1]. It was observed in 60% of the mutation carriers and none of those without the mutation (p < 0.001).

Swoop Portable MRI Cleared in U.S. for Bedside Scans
Magnetic resonance imaging (MRI) has become an integral part of medical care throughout much of the world, but access to this technology remains limited. Conventional MRI scanners need dedicated rooms with entry protocols, quench venting, and safety measures, and patients have to be taken to where the machine is located, often at a distant corner of a hospital. Earlier this year, Hyperfine, a company with offices in New York City and St Guilford, Connecticut, won the first FDA clearance for a portable MRI that can be taken into patient rooms. Now, the company has obtained FDA clearance for its second generation portable MR...

This is double plus ungood news
It ' s one study, and it isn ' t very long follow-up, just two or three months, butthis is a very ugly result. German researchers did magnetic resonance imaging of the hearts of 100 people who had recovered from Covid-19. Two thirds of them had not been hospitalized. It turned out that 78% of them had abnormal results indicating inflammation of the heart muscle, and/or reduced cardiac functioning, regardless of the severity of their illness. They don ' t fully explain how the sample of patients was obtained but they describe them as " unselected, " in other words they are assumed to be representative of all patients ...
