					<description><![CDATA[Some years ago, some Doctor Class here was replying to my comment about Chinese medicine and research on the microbiome. That wasn&#039;t in the medical textbooks apparently for Doctor Class here so... this just sounded like mumbo jumbo chin chin sounds to the Doctor Class Authority.

Meanwhile, in these days, supermarkets have probiotics and doctors are telling their families to use probiotics to... aid their destroyed gut bacteria in the microbiome.

See how you humans are ridiculous over the years?]]></description>

					<description><![CDATA[&lt;i&gt;But, for a while at least, the science was settled.&lt;/i&gt;

I suspected something like that. Great story, though.

Cicero, the cases I was referring to were divided corpus callosum, not hemispherectomy.  They were done for post trauma seizures.  The Argentine boy case was a child of about 5.

					<description><![CDATA[Dr. Mike K:
A relatively small number of cerebral hemispherectomies were done in the 1950s as desperation therapy for glioblastomas (for the rest of you, the malign brain tumor that killed McCain and the &#039;Lion of the Senate&#039;). Yielded the expected profound neuro deficits (hemiplegia, etc,) but did not, repeat not, extend survival over less radical resection. So standard of care became whole brain irradiation, which added some weeks (10-12) to survival over partial resection alone, but at the cost of creating a fair # of human cabbages. Fortunately CT, then MRI came along a generation later, facilitating much more precise resection, but now even with today&#039;s best triple therapy (surg, irradiation, chemo) median survival has been extended only from ~30 weeks to ~65 weeks.  Wow! Median survival has doubled! But it is almost universally fatal in a still rather short time.]]></description>

					<description><![CDATA[A snatch from Wiki on diffusion-weighted MRI:

Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches).[9] MRI can be made sensitive to the motion of molecules. Regular MRI acquisition utilizes the behaviour of protons in water to generate contrast between clinically relevant features of a particular subject. The versatile nature of MRI is due to this capability of producing contrast related to the structure of tissues at microscopic level. In a typical {\displaystyle T_{1}} T_{1}-weighted image, water molecules in a sample are excited with the imposition of a strong magnetic field. This causes many of the protons in water molecules to precess simultaneously, producing signals in MRI. In {\displaystyle T_{2}} T_{2}-weighted images, contrast is produced by measuring the loss of coherence or synchrony between the water protons. When water is in an environment where it can freely tumble, relaxation tends to take longer. In certain clinical situations, this can generate contrast between an area of pathology and the surrounding healthy tissue.

To sensitize MRI images to diffusion, instead of a homogeneous magnetic field, the homogeneity is varied linearly by a pulsed field gradient,
