Ultrasound Imaging Using Only Piezoelectric Organic LEDs
At North Carolina State University, researchers have performed a remarkable trick, namely producing ultrasound images using nothing but piezoelectric organic light emitting diodes. This may be a big deal, as existing ultrasound devices rely on electronics and image reconstruction algorithms to convert sonic waves captured by transducers into intuitive renderings. Avoiding these altogether may allow for much cheaper, smaller, and more capable ultrasound systems, potentially revolutionizing the entire industry. The researchers believe that conventional devices, that currently cost tens of thousands of dollars, may soon be re...

What ’ s the relationship between JVP and PCWP/LVEDP?
This study elegantly shows a correlation (or lack of it) in different subsets of heart failure. It tells us very clearly If JVP(RAP) is not correlating or disproportionate to PCWP, it implies RV dysfunction.
2. This paper suggests a really useful scheme to classify heart failure as concordant and discordant with reference to right and left heart.
It throws some interesting facts. I guess it will help us guide diuretic management and prognosticate chronic heart failure. (Source: Dr.S.Venkatesan MD)

The Baseline of Order
I live in a gated community with fairly strict standards that all homes have to follow. Anyone who wants to live in the neighborhood must contractually agree to these standards. If anyone falls short of them, they’ll get a letter from the community management association with a request to bring their property up to standard. If they don’t comply, the community association has the authority to fine them and to seek other remedies.
We’re not even allowed to park our own cars on the street, only in our driveways or garages, so there are hardly any cars on the streets. No one can park an RV on the street, ...

Forgiveness: Yes? No? Maybe?
“My step-father abused me, and my mother is always telling me to forgive and forget.” Jodie shook her head ruefully.
“And how is that going for you?” I ask.
“Not so good,” Jodie replies, “I’m not doing a good job at all.”
Alex shares, “My counselor told me if I don’t forgive my uncle for raping me, then I’m allowing him to live rent-free in my head.”
“And how is that going for you?” I ask.
“Not so good,” Alex cries, “I feel like I’m failing at recovery!”
Both Jodie and Alex — and countless other survivors I work with — have been instructed that to forgive and to forget is...

Fight Aging! Newsletter, July 27th 2020
In this study, we applied a well studied prediction model developed on data from five CpG sites, to increase the practicability of these tests.
We have determined the biological age of the heart, specifically of the right atrium (RA) and left atrium (LA), and of peripheral blood leucocytes, by measuring the mitotic telomere length (TL) and the non-mitotic epigenetic age (DNAmAge). We found that DNAmAge, of both atrial tissues (RA and LA), was younger in respect to the chronological age (-12 years). Furthermore, no significant difference existed between RA and LA, suggesting that, although anatomically diverse and ex...

Plant “Cognition” Deserves Greater Attention In Comparative Psychology, Paper Argues
In this study, each plant’s roots were split between two different pots, one of which received a constant level of nutrients, the other a variable level. The overall level of nutrients in these pairs of pots was also varied, so that some pairs had high levels, and some low.
In overall low-nutrient situations, the plants went for the safe option of the pot with the stable (if unsatisfying) level of nutrients, focusing root growth in this pot. But in higher nutrient conditions, they took a punt on the variable-level pot. As Castiello writes: “The experiment showed that plants are able to respond to risk and to switch to ...

Overexpression of Exercise-Related Gpld1 Increases Neurogenesis in Old Mice
Studies based on the transfer of blood or plasma from young mice to old mice are resulting in a number of interesting discoveries regarding important differences in the cell signaling environment that occur with age. Whether it is possible to exploit this knowledge to produce significant gains in human health remains an open question. Early tests of plasma transfer did not produce compelling results, while efforts focused on specific proteins have yet to reach the point of clinical trials. The research noted here is illustrated of many lines of inquiry presently underway, in which a novel signal molecule is identified and ...

Visualizing Energy Flows
Visualizing your goals can be helpful, but don’t limit your visualizations to the same types of scenes you’re accustomed to seeing with your eyes. Your mind is a lot more powerful than your eyeballs.
Note also that your visual cortex is only about 0.5% of your brain. Consider what more is possible if you could invite yourself to visualize with some of the other 99.5% – which may have capabilities extending far beyond what the visual cortex can do. Your computer is more than just a webcam and a screen.
I often find it more powerful and effective to visualize energy flows instead of actual scenes I might ...

The Purposeful Parenting Mindset
July is National Purposeful Parenting month. Purposeful Parenting is a movement that has gained popularity over the last decade. It is based on the belief that when the parental role is established with proactive intentionality and thorough understanding about child development, the ability of children to fulfill their potential and have more options available to them increases.
Purposeful Parenting has strong roots in the age-old debate between the roles of nature versus nurture in development. Prior to this movement, many parents and professionals viewed growth as a kind of predetermined outcome that naturally evolved....

Injectable Liquid Prosthesis to Treat Retinal Diseases Developed
Retinal prostheses promise the restoration of vision to people with age-related macular degeneration, retinitis pigmentosa, and other conditions that lead to the loss of functional photoreceptors. A number of technologies are already in existence that mimic the functionality of the retina by stimulating the inner retinal network, but most of these rely on wearable cameras, special glasses, computers, and wiring to interface with the eye. Moreover, the results are highly lacking and the achieved vision is extremely low resolution. At the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology), scientists have ...

Lifestyle Medicine Could Be The Key For Digital Health Adoption
I’ve been wearing my Fitbit for a couple of years and only remove it when I shower. I use it to track my sleep and its smart alarm wakes me up at the optimal time every morning. With the pocketable Kardia, I regularly check my ECG at home to detect any anomalies. For an in-depth analysis of what my genetic makeup predisposes me to, I had my whole genome sequenced. And I bring relevant data to my general practitioner during my checkups so that we can decide on preventive measures. In short, I’m trying to live like the patient of the future.
However, posing as such a patient is not feasible for many among us. Firs...

The Sweet Psychology of Indulging During a Pandemic
The pandemic has ushered in an era of relentless challenges, from everyday inconveniences to unimaginable pain and hardship. But not for the processed food industry. The titans of that sector are salivating over their great good fortune.
Processed foods include all sorts of treats we are not supposed to eat: Sweet things and salty things, packaged for convenience and designed for a long shelf life and maximum irresistibility. Things like grocery store cookies and cakes, canned soups and breakfast cereals and frozen waffles. And chips. Lots and lots of chips. Sales of those kinds of foods are surging.
Cooped up Americans ...
