ありがとうございます。あ、先生、どうぞ。あの、ここのセントラルイラストレーションですね。ちょっと今お出ししておりますけれども、今おっしゃっていただいたような背景以外にファラパルス二十八例、もうここはおっしゃっていただきましたね、この七十二例の内訳、それから平均年齢七十歳、男性七十六パーセント、そして発作性心房細動六十一パーセント、持続性 AF が三十九パーセントということだと思いますけれども。そうしましたらですね、あとはこのやっぱりセントラルイラストレーションに今回の論文の内容、ほとんどが積み込まれているという形で、これ見れば結構わかるよっていう状況かもしれませんけども、先生、じゃあ左上の方から順々にですね、ちょっとご解説いただければと思います。

先ほどお話しした通りで、対象群はですね、対象患者は七十二例になりまして、そのデバイスがファラパルスというデバイスが二十八例なんですけども、このファラパルスというのは実は一番パワーが強いものなんですね。で、バリパルスというのが二十一例、これは中間ぐらい。で、パルスセレクトというのがですね、一番エナジーは弱いんですけれども、たくさん打ってもいいよっていうことで、各者いいとこメリットデメリットあるんですけれども、そういった三つのデバイスを使っています。 下のですね、VOM venography というのが実際にマーシャル静脈をはい、写したところになるんですけども。あ、すいません。ちょっと待って。あのマーシャル静脈がこの矢印で示してあるところで、見えますかね、すごくこう細くて、あの非常にtinyな血管になるんですけども、これがマーシャル静脈というもので、ここにですね、あの右側の絵でちょっと見えてますかね、一点六フレンチの電極カテーテルを、この細いのですね、そこですね、それを入れてみます。その上でアブレーションしてるんですけど、この左から出てる、あの、このアブレーションの過程っていうのは、これがパラパルスというやつですね。一番パワーの強いやつを当ててるところの絵になります。はい、そうなります。で、あの、これリアルタイムにあのずっと電気を見ながらあのやっているんですけれども。で、一応結果としましてはですね、右下のアキュート PFA エフェクトオン V1 の右側の方ですねとなります。あ、すいません、その、えーと、そこです。はい、それになりますけども、結果としましては、このいわゆるパルスアブレーションした、そのリアルタイムのその通電中にですね、電位が消えたのが十六例、二十二パーセントで、電位が減光したのも十六例、二十二パーセントということで、合計すると四十四パーセントに、何らかのマーシャル静脈に対する素速-- 束縛ダメージ、束縛のエフェクトがあったということになります。それで、あの、その左のグラフになりますけども、ここはちょっと着目していただきたいのが、今回の研究ではですね、このパルスフリーアブレーションの電極とマーシャル静脈に入れた電極の間の距離をですね、これは透視場で測ってるんですけど、測ったものを計算してるんですけども、距離を直線距離を一応測っておりまして、その結果としましてですね、あの、あのエフェクトがなかった例と、真ん中が減光、電位が減光した例と電位が消えた例で、あの、電位が、あの、どんどんどんどんエフェクトが強くなるにつれて、そのマーシャル静脈とパルスアブレーション電極の距離が短くなったということなんですね。つまりその距離が近ければマーシャル静脈に対するエフェクトも強いということで、要するに PFA エフェクトというのは要するに距離に依存しているというような結果になりました。で、一応ですね、先生、次のじゃあ少しスライドをちょっと出していただいてよろしいでしょうか。えっと、この次の距離の。はい、すみません。
Mitsuaki SawanoHOST
15:13
中川先生、ちょっとだけ質問させていただいてもよろしいですか?ちょっと素朴な疑問なんですけど、この距離ってどういうふうに測定されているのかなというふうに思ったんですけども、このすごく近い距離のところをどういった形で、あの、この PFA と、それからマーシャルベインとの距離ってどういう形で測られてるんでしょうか。
Yosuke NakataniGUEST
15:38
これはですね、透視で測ってるんですね。そこはちょっとあの、少しあのリミテーションになっちゃうかなとは思うんですけれども、あの一応その、いわゆる我々3Dマッピングですね、まああの、いわゆる実際に三次元マッピング上では、このカテを配置して距離って一応測れることは測れるんですけれども、少々難しいのがですね、この各社で、あの、そのアブレーションの時に使うその3Dマッピングシステムが違うんですよね。ですから、このマッピングシステムの違いがですね、この距離の測定に影響してしまう可能性があったもんですから、あの、全てのシステムで同じ透視で測るということで、透視で測った距離をユークリッド距離ですね、直線距離に出し直して測ったという形になります。

Yeah, and the other point, too, I think power is or will become the real bottleneck.
Gary SloperHOST
13:21
So if we dive into electricity overall, because it's a key part of the entire AI infrastructure story, like we've discussed in episode 66, Energy and the AI Race.
Gary SloperHOST
13:32
So if you haven't listened to that episode, go back.
Gary SloperHOST
13:34
That's a good one.

You have to put energy in.
speaker_0UNKNOWN
1:00
Forming bonds releases energy.
speaker_0UNKNOWN
1:03
Energy comes out.
speaker_0UNKNOWN
1:04
The overall energy change of a reaction depends on which of these processes dominates.
speaker_0UNKNOWN
1:08
In an exothermic reaction, more energy is released when bonds form in the products than is taken in to break bonds in the reactants.
speaker_0UNKNOWN
1:16
The result? Energy is transferred to the surroundings, and the surroundings get warmer.
speaker_0UNKNOWN
1:21
the temperature of the solution or the surroundings goes up think of burning wood neutralization reactions or hand warmers these are all exothermic in an endothermic reaction more energy is taken in to break bonds in the reactants than is released when bonds form in the products Energy is taken from the surroundings, and the surroundings get cooler.
speaker_0UNKNOWN
1:43
The temperature goes down.

[upbeat music] Welcome to Project Vanguard Podcast, home of the community of veterans and energy, where we explore the journeys of veterans leading in energy.
Kevin DoffingHOST
0:14
We're building American energy dominance through an all-the-above approach, where energy security is national security, and our mission is to double the number of veterans working in the energy industry.
Kevin DoffingHOST

I'm your host, Kevin Dolphin.
Kevin DoffingHOST
0:30
Today, I'm sitting down with Ryan Lamke, who runs the Veterans Advanced Energy Fellowship at the Atlantic Council.

What came next was working with the Wounded Warrior Project, then attending community college in Georgetown, and even a stretch of running PR on the NASCAR circuit.

Finally, he went to the Department of Energy, where he ended up as a senior advisor on China.
Kevin DoffingHOST
1:04
We talk about why energy is now the thing every piece of modern war fighting depends on, and what he's putting this year's fellows to work on with the Atlantic Council, and why saying, "I don't know," has earned him more trust than any credential on his resume.
Kevin DoffingHOST
1:22
Let's get into it.
Dave FarinaHOST
0:10
Time dilation and length contraction are two of the bizarre ramifications of Einstein's special relativity.
Dave FarinaHOST
0:18
But we have one more to get through, and it comes in the form of his most famous equation, which is arguably the most famous equation in all of science, E equals MC squared.
Dave FarinaHOST
0:30
Almost everyone can recite this equation from memory, but far fewer know precisely what it means.
Dave FarinaHOST
0:36
It outlines the concept of mass-energy equivalence, stating that energy is equal to mass times the speed of light squared.
Dave FarinaHOST
3:09
Beyond this, faster than light travel implies problems with simultaneity, whereby an effect could happen before its own cause, which violates causality.
Dave FarinaHOST
3:21
So we must accept that for all these reasons, the speed of light absolutely can never be attained or surpassed by any massive object, for reasons that are fundamental not just to physics, but to mathematics and logic as well.
Dave FarinaHOST
3:38
E equals MC squared has many implications, given the incredible conclusion that energy and mass are equivalent.
Dave FarinaHOST
3:45
Mass is energy, and incredibly dense energy at that, since to get the energy contained in some amount of matter, you multiply its mass by the speed of light squared, which is a huge number.
Jay FeldmanHOST

So I'll go ahead and read this quote, which states, "Cancer cells cannot effectively use ketone bodies or fatty acids for ATP synthesis through oxidative phosphorylation due to defects in the number, structure, and function of their mitochondria.
Jay FeldmanHOST
4:57
Moreover, ketone bodies and fatty acids cannot be fermented and thus cannot effectively replace glucose and glutamine as an alternative energy source for cancer.
Jay FeldmanHOST
5:06
Bartman et al.
Jay FeldmanHOST
5:07
showed that the major ketone body, beta-hydroxybutyrate, could not stimulate breast tumor growth in vitro.
Jay FeldmanHOST
5:13
Hence, ketogenic metabolic therapy becomes a putative therapeutic strategy for managing most cancers, including breast cancers." He goes on to state, "There have been reports, however, suggesting that some cancers, including breast cancer, can oxidize ketone bodies and fatty acids for growth.
Jay FeldmanHOST
5:28
The uptake of ketone bodies or fatty acids together with oxygen consumption in tumor cells is not proof that the ketone bodies or fatty acids can be used to generate energy through oxidative phosphorylation.
Jay FeldmanHOST
5:40
Fatty acids can stimulate utilization of glucose and glutamine.
Jay FeldmanHOST
5:43
Also, palmitic acid cannot support in vitro tumor growth in the absence of glucose and glutamine.
Michael RussellHOST

Sit back, relax, and let's start talking about chapter three.
Michael RussellHOST
1:05
Electromagnetic energy is the energy that's around us all the time.
Michael RussellHOST
1:10
Some of it we're used to.
Michael RussellHOST
1:12
So, for example, light.
Michael RussellHOST
1:28
And that led into all kinds of interesting discoveries.
Michael RussellHOST
1:31
And then later on, a guy named James Maxwell discovered that visible light is part of the electromagnetic spectrum.
Michael RussellHOST
1:38
Electromagnetic spectrum is actually more than just visible light.
Michael RussellHOST
1:42
It's actually infrared, which is used sometimes to heat food, ultraviolet, which gives me a sunburn when I'm out in the sun too long, but anyway, that's my problem.
Michael LiebreichHOST
0:59
We're filming this episode in front of a live audience on the opening morning of Climate Week in New York.
Michael LiebreichHOST
1:06
There's an old joke that fusion energy is 30 years away and always will be.
Michael LiebreichHOST
1:11
For many decades, the industry did little to spoil the fun, running mammoth and unwieldy research projects, hoovering up a few billion dollars every science funding cycle in the major economies, and announcing breakthroughs that were scientifically interesting, but did little to move us towards actual production of electricity.
Michael LiebreichHOST
1:32
Then three things happened.
Michael LiebreichHOST
1:34
First, perhaps emboldened by Elon Musk's successful disruption of the space industry with SpaceX, a bunch of wealthy investors started to invest in much nimbler startups.
Michael LiebreichHOST
1:47
Then, in December 2022, the National Ignition Facility at the US's Lawrence Livermore National Lab announced that it had finally got more energy out of a fusion experiment than it had put in.
Michael LiebreichHOST
2:00
And third, AI exploded on the scene, offering dramatic acceleration in everything.
Michael LiebreichHOST
2:08
These developments have turned the slow-moving world of Fusion with its foundation stories dating back to Ernest Rutherford, Enrico Fermi, Andrei Sakharov on its head.
Eric DollardGUEST
47:03
What it's doing is taking primary force, for the lack of a better word, primary induction, okay? Which is invisible and insensible to us, and we have no instruments which to measure it.
Eric DollardGUEST
47:17
And it's converting it into energy or, you know, electricity or however you want it.
Eric DollardGUEST
47:23
E-energy is, is not a good dimensional relationship to use.
Eric DollardGUEST
47:27
It's very limited.
Eric DollardGUEST
47:28
There's a, there's a higher up from that, uh, but which electricity occupies.
Caroline AlanGUEST
11:40
So whether it's making thyroid or it's making adrenals or it's making reproductive hormones or it's making digestive enzymes or it's making proteins, it's all of the biosynthesis that happens in your body to regenerate bones, to, to make your body work requires different minerals as co-factors.
Caroline AlanGUEST
11:59
So while we've been focusing mostly in the world now, we focus on macros, carbs, fats, and proteins, guess what? None of those can be utilized by your body if you don't have all of the mineral co-factors necessary to turn those things into energy.
Jennifer NormanHOST
12:15
energy.Mm.
Caroline AlanGUEST
12:16
So that's the next thing.
Caroline AlanGUEST
12:19
So minerals are structure, minerals are co-factors for biosynthesis, and next they are co-factors for most energy generation in the body.
