1
Many individuals suffering from the medical condition known as diabetes rely on artificial insulin to maintain good health.
2
The principal means of delivering insulin to the body is via injection,
3
but work is being done to develop other reliable means of administering it without having to use a syringe.
4
Charlotte Newman reports.
5
Diabetes is a condition in which the body does not release or properly respond to insulin, a hormone produced in the pancreas.
6
Many diabetics require regular insulin injections to regulate their blood glucose levels, in some cases, as many as 10 or more shots a day.
7
Although insulin injections allow diabetics to live full and active lives, the treatment does have inherent disadvantages.
8
But at Syracuse University in New York, a new delivery method is currently under development.
9
Insulin chewing gum.
10
Chemist Max Garcia is here to tell us more.
11
Well, while many diabetics inject themselves regularly without any real discomfort, some do experience pain and itching where the needle breaks the skin.
12
A condition known as lipodystrophy in which the skin puckers can even develop at the site of multiple injections.
13
At affected areas, the absorption of insulin may be impaired, making it difficult to calculate the correct dosage.
14
Oral delivery of insulin would, therefore, be a preferable treatment.
15
But the development of pills
16
and capsules has been hampered by various problems relating to the physical and chemical stability of the hormone.
17
One major challenge has been to find a way to protect insulin from the hostile conditions in the digestive system.
18
Apparently, insulin molecules delivered by mouth will be broken down by the high acidity they encounter in the digestive tract.
19
Scientists have tried various strategies to overcome this obstacle.
20
And now the team at Syracuse has come up with a potential solution.
21
That's right.
22
Using their knowledge of the digestive system,
23
our scientists realized that the body has a mechanism to protect valuable molecules as they pass through the digestive system.
24
So the team decided to chemically bind insulin molecules to vitamin B12,
25
A protein called haptocorin, present in the saliva in the mouth,
26
joins with this particular vitamin to ensure its safe passage through the stomach to the intestine.
27
The research team's idea was simply for the insulin to hitch a ride, as it were, along with a protected vitamin.
28
This particular vitamin seems to be a very good choice once
29
the b12 reaches the intestine intact another chemical takes over from the haptocorin to help it enter the bloodstream
30
so by binding insulin to vitamin b12 the chances of it
31
being absorbed into the bloodstream are optimized early tests with rats indicate
32
that the researchers are on the right track in these tests the new treatment was administered in liquid form
33
but chewing gum would probably be a more efficient medium for human beings.
34
Through the chewing action, we could ensure sufficient haptocorin is produced.
35
If this solution proves feasible and viable,
36
diabetics might one day be able to throw away their syringes and reach for a pack of 1.
37
What is one reason why researchers want to find an alternative delivery system for insulin?
38
Number 2.
39
What difficulty has impeded attempts to develop an oral insulin treatment?
40
Number 3.
41
What breakthrough did the chemists at Syracuse University make?
42
Number 4.
43
In which part of the body does haptocorin's protective function end?
44
5. What is the current status of the research into chewing gum as a medium for insolent?
45
Number 1.
46
What is one reason why researchers want to find an alternative delivery system for insulin?
47

  3. 自分の声を録音して元の音声と比べます。insulin, vitamin, chewなどの単語に特に注意しましょう。

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
