[AstroDigi] [en.ASTRODIGI.com] MANDY SELLARS, A British Woman with Gigantic Legs

Most-expensive.net | September 20, 2008 | Russian woman Svetlana
Pankrtova stunned the world for her longest legs of any woman
recognized by Guinness World Records. British woman Mandy Sellars now
also attracted the similar international attention for her own
(gigantic) legs, but apparently the latter is not as lucky as the
former.

Mandy Sellars (pictured here), 33, from Lancashire of England, may be
suffering from an extremely rare disease called Proteus syndrome
[wikipedia] that left two of her legs weighing 92-98kg out of total
body weight about 130kg. What’s the worse, the abnormal legs never
stops growing, and one day, they may have to be amputated.



Sellars is 33 years old and weighs 285 pounds [129kg]. Her upper torso
is a petite size 8 and accounts for only about 70 or 80 pounds
[31~36kg] of her weight. The rest is in her legs and feet.

“When I was born, there was a noticeable difference between my upper
body and my lower body,” Sellars said. “They didn’t actually expect me
to live further than about a few, a few days or so.”

A Tough Job for the Shoemaker

Throughout her childhood, the growth of her legs continued to outpace
the rest of her body until she could no longer move on her own. She
walks now with the aid of crutches and drives a specially equipped
automobile.

Near her home in northwestern England, Sellars goes to a private
shoemaker. Her right foot is 16 inches [41 cm] long and 7 inches [18
cm] wide, and her legs are of differing lengths because the left foot —
a club foot, 11 inches [28 cm] long — faces backward.


So the fittings are delicate. It takes weeks of trial and error to
produce the final molds for a pair of boots, and they will cost around
$4,000 — money she has to raise because she is unemployed.

Because her condition remained such a mystery, she often seemed to be
on the edge of disaster. In college, she was once suddenly paralyzed
because of a blood clot that required 10 weeks of hospitalization. When
a plastic surgeon tried liposuction to reduce the bulk in her legs,
more tissue grew back than had been removed.

“In my mind, the condition has a mind of its own,” Sellars said,
“because whatever you take away grows back bigger and bigger.”

It was through the Internet that she finally began to get a clue about
what her condition might be. A friend of hers came across the site of
an organization in Great Britain called the Proteus Syndrome Foundation
U.K.. That finally led to a diagnosis, one that Sellars had been
waiting years to receive. The unusual growth of her legs and knees was
common to people with Proteus syndrome

“This is a very rare disorder. Certainly, less than one in a million,”
said Dr. John Graham, director of clinical genetics at Cedars-Sinai
Medical Center in Los Angeles. “Proteus syndrome is named for the Greek
God who could change his form. And because it was such an apt
description of how these individuals rapidly change form from appearing
relatively normal as young children to this startling overgrowth, the
name has remained with the disorder ever since then.”

The most famous case of Proteus syndrome in history was that of Joseph
Merrick, also known as the Elephant Man, who died in 1890 and was the
subject of a well-known movie about his life.

Thinking Ahead

Sellars lives independently in a home that has been only slightly
modified for her, but even common household tasks — fixing a cup of tea
— can be exhausting. She visits a nutritionist, hoping she can lessen
the effects of Proteus syndrome through diet, but so far, it hasn’t
helped. She has been told that eventually she may need to amputate her
legs. She’s already considering how she will live her life then and has
even thought about entering the London Marathon as a wheelchair racer.

“I’d love to do that,” Sellars said, “and hopefully then be able to
wheel myself and train hard enough to be able to do that, and raise
money for charity that’s helped me.”

[AstroDigi] BAGHEERA KIPLINGI, Laba-laba Vegetarian

2010-08-27 Terurut Topik NINO
KOMPAS.com | Rabu, 14 Oktober 2009 | Laba-laba Bagheera kiplingi yang
hidup di Meksiko dan Kosta Rika merupakan laba-laba vegetarian pertama
di dunia.
Hampir semua spesies laba-laba merupakan jenis predator yang memangsa
hewan lainnya, dari serangga sampai burung. Di antara lebih dari 40.000
spesies laba-laba yang ada di dunia, laba-laba yang baru ditemukan ini
mungkin jenis pertama diketahui makan tumbuh-tumbuhan.

Hewan berkaki delapan yang diberi nama Bagheera kiplingi itu, hidup di
Amerika Tengah khususnya Meksiko dan Costa Rika. Laba-laba vegetarian
yang besar tubuhnya hanya seukuran kuku orang dewasa itu memangsa ujung
daun akasia.

Ini benar-benar laba-laba pertama yang diketahui memangsa
tumbuh-tumbuhan. Ia juga laba-laba pertama yang diketahu menjadikan
tumbuh-tumbuhan sebagai mangsa pokoknya, ujar Christopher Meehan dari
Universitas Villanova, Pennsylvania, AS yang melaporkan penelitian
tersebut bersama peneliti lainnya dalam jurnal Current Biology edisi
teranyar. Ia mengatakan hampir semua buku teks laba-laba tak ada yang
pernah menyatakan ada laba-laba pemakan tumbuh-tumbuhan.

Dalam memperoleh sumber makanan ia cukup dibantu peran semut penjaga
yang hidupnya juga di pohon akasia. Pasalnya dengan semut yang
menguasai akasia, tidak ada herbivora lainnya yang berani mendekat.
Namun, karena semut juga makan ujung daun, selain nektar, laba-laba
harus melakukan strategi khusus.

Saat berburu mangsa, laba-laba tersebut harus menghindari smeut penjaga
dengan memanfaatkan jaringnya untuk bergerak naik turun. Laba-laba juga
membangun sarangnya di pangkal daun akasia tua yang jarang sekali
dilalui semut.

Selain memangsa ujung daun, laba-laba tersebut sebenarnya masih
memangsa lainnya seperti larva semut dan nektar. Saat memengsa semut
mereka akan berpura-pura menjadi semut dengan melakukan gerakan zig-zag.

Meski demikian, pengamatan yang dilakukan menggunakan rekaman video dan
analisis kimia menunjukkan laba-laba tersebut tetap mendapatkan
sebagian besar makanan dari tumbuhan. Populasi di Meksiko memperoleh 90
persen makanan dari jaringan tumbuhan dan sisanya larva semut, nektar,
dan lainnya. Sementara populasi di Kosta Rika memperoleh 60 persen
makanan dari daun akasia.
