Welcome! Whether family or friend or stranger, I hope you find something here to amuse, entertain or inform. It's rather an eclectic mix which has lain moribund for quite some time but I hope to get it up and running again!

Any suggestions as to additional content should be emailed to me at roheithir AT gmail DOT com. Recipes are especially welcome!

The two most beautiful places in the world IMHO - Rwanda and the Aran Islands.

These are extracts from the speeches of Donald Rumsfeld written out as poems and published by Hart Seely in 2003. They have also been set to music (follow this link for more info)

As we know,
There are known knowns.
There are things we know we know.

We also know
There are known unknowns.
That is to say
We know there are some things
We do not know.

But there are also unknown unknowns,
The ones we don't know
We don't know.

Glass Box
You know, it's the old glass box at the-
At the gas station,
Where you're using those little things
Trying to pick up the prize,
And you can't find it.

And it's all these arms are going down in there,
And so you keep dropping it
And picking it up again and moving it,

Some of you are probably too young to remember those-
Those glass boxes,

But they used to have them
At all the gas stations
When I was a kid.

We showed previously that this phenotype is associated with a structural gene mutation that produces an exceptionally labile enzyme. We now report on the nature and consequence of this mutation. When the mutant arylsulfatase -a is deglycosylated by endoglycosidase h , only one smaller molecular species was generated, instead of the two from the normal enzyme. This is consistent with the loss of one of the two n-linked oligosaccharide side chains known to be present on the wild-type enzyme. Quantitative analysis of mannose and leucine incorporation showed that the mutant enzyme incorporated two- to tenfold less mannose than the normal enzyme on a molar basis. This deficient glycosylation was specific to arylsulfatase -a. Another lysosomal enzyme not affected in this mutation, beta-hexosaminidase , was glycosylated normally in the mutant cells. The remaining single oligosaccharide side chain released from the mutant arylsulfatase -a by pronase digestio. Department of Defense news briefing
