The Impact of Stress on Telomeres and Aging
- Each time a cell in our body is replaced, part of our DNA, called telomeres, shorten.
- Stress accelerates the process of cell reproduction and replacement, leading to the shortening of telomeres.
- Short telomeres result in cells ceasing reproduction and accelerate the aging process.

英語長文 の質問です。 Each time a cell in our body is replaced, part of our DNA, called telomeres, shorten. この文章で、何がshortenなのか（何がshortになるのか）わからず、この文章が訳せません。アドバイスお願いしますm(_ _)m ちなみにこれはストレスが寿命を縮めるという説明文で、前後関係はこうなってます。↓ The researchers discovered in their tests that the system of cell reproduction and replacement, which of couse keeps us going, becomes faster under times of stress. 【Each time a cell in our body is replaced, part of our DNA, called telomeres, shorten. 】When they become too short, cells stop reproducing and our bodies continue aging. This means longer telomeres lengthen our lives. Stress makes them shorter, and so we die earlier. The simple message, therefore,is to take it easy. 長くてすみません；； よろしくお願いします。

>何がshortenなのか（何がshortになるのか）わからず 間にcalled telomeresが入っているから分かりにくくなってますが、part of our DNAが主語でshortenは動詞です。 体内の細胞が置き換わるたびに(置き換えられるたびに）、DNAの一部（テロメアと呼ばれる部位）が短くなる。 位の意味でしょう。専門分野は門外漢なので後は適当に補ってください。

要するに、Each time a cell in our body is replaced, part of our DNA, called telomeres, shorten. という文の shorten の主語が分らないということですね？ part of our DNA, called telomeres の部分が主語です。 文意は、「細胞が再生される毎に、DNAの一部、つまりテロメアと呼ばれる部分が、短くなる」ということでしょう。

1.4 DNA structure and function DNA is huge ladder-like molecule made up of sugar , phosphate and four organic bases called Adenine, Guanine, Cytosine and Thymine.The bases will only join up in the pairs A to T and G to C. The two halves of the ladder can also un-zip between the pairs of bases.They do this: (a) At mitosis: each half ladder forms the other half on itself.So two ladders,which are identical, result.This is the reason why a chromosome that splits in mitosis forms two identical chromosomes. (b) When genes make proteins: each half ladder forms a related substance, RNA(very similar to DNA) on it.This then detaches, passing to the ribosomes.RNA carries the sequence of bases that were in the DNA.Each three letter ‘word’(triplet),e.g.AGC attracts particular amino acid to the ribosome. The sequence of the hundreds of triplets is what determines the kind of protein formed at the ribosomes-each protein has its own unique DNA sequence. Thus a length of DNA with its own unique sequence is a gene; and a gene is what is used to make its own, unique,protein by linking a particular sequence of amino acids together at ribosome. The‘ladder’structure of DNA is in fact turned into a spiral(double helix) thread,with 10 base pairs per complete 360°turn.This has little to do with the function of DNA but it was a crucial fact, discovered by Franklin, Wilkins, Watson and Crick, in determining its structure. かなり長いですがお願いします。 すごく急いでます。

A spotless Rose is blowing, Sprung from a tender root, Of ancient seers' foreshowing, Of Jesse promis'd fruit; Its fairest bud unfolds to light A mid the cold, cold winter, And in the dark midnight. The Rose which I am singing, Whereof Isaiah said, Is from its sweet root springing In Mary, purest Maid; For through our God's great love and might, The blessed Babe she bare us In a cold, cold winter's night この歌詞の中から名詞だけ抜き出してほしいです。 お願いします。

【本文】 “We wish to suggest a structure for the salt of deoxyribonucleic acid （DNA). This structure has novel features which are of considerable biological interest.” This is how James Watson and Francis Crick announced in 1956 that they had worked out the structure of the “molecule of life”. Many scientists regard it as the most important scientific discovery of the 20th century. The DNA molecule is like a ladder that has been twisted into a spiral like a corkscrew. Four base molecules are spread along the legs of the ladder: A （adenine）, T（thymine）, C（cytosine）， and G（guanine）. The rungs of the ladder are bonds linking the four base molecules on the ladder legs. A is always linked with T and C is always linked with G. The DNA molecule reproduces itself by unwinding the two legs of the ladder. Each leg then combines with a new leg and two identical molecules are formed. This is how living organisms are able to reproduce. Each cell in our body is about one millionth of a meter in diameter, but contains about two meters of DNA. Every living organism, plant or animal, is determined by its DNA and the way the four base molecules are arranged. The arrangement of those four base molecules determines whether the organism is, for example, a plant or an animal, a mosquito, an elephant or a human being. And each individual within a species has its own DNA, which determines whether that individual has straight or curly hair, or fair or dark skin. Scientists are now using DNA to study our history. In the 19th century, anthropologists found fossil remains of what they thought were early human beings. They called them “Neanderthal man” after the valley in which their remains were first found. It was thought that they were our ancestors and that we had evolve from them. However, comparisons of Neanderthal DNA with DNA of modern humans showed that while we do have an ancestor in common, we developed from this common ancestor separately. We now know that the Neanderthal line of development split from the human one about 500,000 years ago. Neanderthals and humans are different species just as chimpanzees and humans are different species. DNA studies show that all modern humans descended from one woman who lived about 200,000 years ago. In the movie Jurassic Park, scientists bring extinct dinosaurs back to life. They use dinosaur DNA taken from preserved mosquitoes that fed on dinosaur blood. This may no longer be science fiction. The first successful extraction of DNA from an extinct animal was done in 1984. The quagga was an African animal very closely related to the zebra, with very similar DNA. The quagga used to be common in Africa, but became extinct in 1887. In 1984 scientists at The University of California extracted quagga DNA from a skin preserved in a museum. The South African Museum has set up a program to clone the quagga using zebras as host mothers. Scientists at the Australian Museum in Sydney have isolated the DNA of a Tasmanian Tiger, which became extinct in 1936, aiming to bring it back as well. The problem with bringing dinosaurs back is that they have been extinct for 65 million years. It is unlikely that any dinosaur DNA has survived. 問題のURLはこちらです。http://detail.chiebukuro.yahoo.co.jp/qa/question_detail.php?qid=1027265645 この問題の自分の答えがd.a.b.c.d.a.になりました。 答え合わせよろしくお願いします。

As the axial load is gradually increased in increments, the total elongation over the gauge length is measured at each increment of the load and this is continued until failure of the specimen takes place. Knowing the original cross-sectional area and length of the specimen, the normal stress and the strain can be obtained. The graph of these quantities with the stress along the y-axis and the strain along the x-axis is called the stress-strain diagram. The stress-strain diagram differs in form for various materials. The diagram shown below is that for a medium-carbon structural steel. Metallic engineering materials are classified as either ductile or brittle materials. A ductile material is one having relatively large tensile strains up to the point of rupture like structural steel and aluminum, whereas brittle materials has a relatively small strain up to the point of rupture like cast iron and concrete. An arbitrary strain of 0.05 mm/mm is frequently taken as the dividing line between these two classes. Stress-strain diagram of a medium-carbon structural steel Proportional Limit (Hooke's Law) From the origin O to the point called proportional limit, the stress-strain curve is a straight line. This linear relation between elongation and the axial force causing was first noticed by Sir Robert Hooke in 1678 and is called Hooke's Law that within the proportional limit, the stress is directly proportional to strain or The constant of proportionality is called the Modulus of Elasticity or Young's Modulus and is equal to the slope of the stress-strain diagram from O to P.

Research projicts follow the trends of their times, and life span psychology has developed as the post-war baby boom generation has matured. The current wave of research into ageing and care of the elderlu, for example, can be seen as directly resulting from that generation reaching retirement age. LIFE-TRANSITIONS Gould(1978) developed the idea that adult life consists of a series of transitions, or life changes, which occur ar different times in our lives. The first of these is that of adjusting to the responsibilities of being independent and living away from parental care. Looking after ourselves without someone in the background is quite different from the kinf of independence which occurs when living as part of family group, where there is always someone to fall back on, or to look after you if you become ill. This transition, Gould argued takes place usually between the ages of 16 and 22. Then there is another transition, which takes place during our twenties, in which we develop our own competences and autonomy, and choose our rulus to live by, rather than simply conforming to our parents' rules and principles. A third transition, according to Gould, happens between 28 and 34, as we come to know ourselves better, and learn to come to terms with aspects of our nature which we weren't really aware of before. And the final transition involves accepting that life isn't going to last for ever━that is, developing a sence of our own mortality. This final transition, Gould argued, happens between the ages of 35 and 45.

訳も解釈も難しいです... 長いので手間がかかるとは思いますが 確認したい箇所がたくさんあるので、 どうかよろしくお願いいたします！！ (1)The Internet promises to have particularly far-reaching effects on cognition. In a paper published in 1936, the British mathematician Alan Turing proved that a digital computer, which at the time existed only as a theoretical machine, could be programmed to perform the function of any other information-processing device. And that's what we're seeing today. The Internet, an immeasurably powerful computing system, is subsuming most of our other intellectual technologies. It's becoming our map and our clock, our printing press and our typewriter, our calculator and our telephone, and our radio and TV. (2)When the Net absorbs a medium, that medium is re-created in the Net's image. It injects the medium's content with hyperlinks, blinking ads, and other digital gewgaws, and it surrounds the content with the content of all the other media it has absorbed. A new e-mail message, for instance, may announce its arrival as we're glancing over the latest headlines at a newspaper's site. The result is to scatter our attention and diffuse our concentration.

POINT LATTICES AND THE UNIT CELL Let’s consider the three-dimensional arrangement of points in Fig.15.This arrangement is called a point lattice. If we take any point in the point lattice it has exactly the same number and arrangement of neighbors(i.e.,identical surroundings) as any other point in the lattice. This condition should be fairly obvious considering our description of long-range order in Sec. 2.1 We can also see from Fig. 15 that it is possible to divide the point lattice into much smaller untils such that when these units are stacked in three dimensions they reproduce the point lattice. This small repeating unit is known as the unit cell of the lattice and is shown in Fig.16 A unit cell may be described by the interrelationship between the lengths(a,b,c) of its sides and the interaxial angles (α,β,γ)between them. (α is the angle between the b and c, axes,β is the angle between the a and c axes, and γ is the angle between the a and b axes.)The actual values of a,b,and c, and α,β and γ are not important, but their interrelation is. The lengths are measured from one corner of the cell, which is taken as the origin. These lengths and angles are called the lattice parameters of the unit cell, or sometimes the lattice constants of the cell. But the latter term is not really appropriate because they are not necessarily constants; for example, they can vary with changes in temperature and pressure and with alloying. [Note: We use a,b and c to indicate the axes of the unit cell; a,b and c for the lattice parameters, and a,b and c for the vectors lying along the unit-cell axes.]
