医学論文訳

医学論文訳 During compoud infusion, animals received intraperitoneal (IP) injection daily with the thymidine analog bromodeoxyuridine (BrdU, 50 mg/kg) to score birth and survival of proliferating hippocampal neural precursor cells. Because social interaction and voluntary exercise stimulate hippocampal neurogenesis, mice were housed individually without access to running wheels starting 1 week prior to screening in order to ensure a low baseline of neurogenesis. After 1 week of compound administration, BrdU immunohistochemistry was used to quantify neurogenesis in the SGZ of the brain hemisphere contralateral to the side of infusion. Every fifth section throughout the rostral-caudal extent of hippocampus was analyzed, and the number of BrdU+ cell was normalized against the volume of the dentate gyrus. もう・・いや・・。難しずぎル。 なにか、うまく読むコツとかあるんですかね? 数行読むのにすごい時間かかるんですけど。。

BrdUを注入してBrdU陽性細胞数を調べた..だけなので訳しませんが 私が医学論文など生物系の論文を読むときは、 1.abstractを読みます。 2.結果を示した図や表を探します。その図や表を見て、 3.どういう結果が観測されたかを見ます 4.その結果から、どういう結論をだしたかを見ます。 5.そして、考えます。実験方法は妥当か?他に考えられる結論はないか? 6.そして、前にさかのぼって実験方法や試験方法を読みます そうすると、意味がわかってきます。 例えば、BrdU陽性細胞数を数えているけど、でっかいmouseとちいさいmouseでは陽性細胞数で比較してももともとの細胞数が違うからそのまま比較してはまずいのでは? という疑問がでてきます。そういう疑問が読者からでてくるのを予測して number of BrdU+ cell was normalized against the volume of the dentate gyrus という文があります。 さらに、神経の発達なんてお互いに刺激しあったりとか、そういう外的な要因でも、変動するんじゃないの?という疑問に対して、 mice were housed individually without access to running wheels starting 1 week prior to screening in order to ensure a low baseline of neurogenesis. という文があります。 このように、筆者は実験方法に対していろんなつっこみがあるのを予測して、それに対して反論を既に記載しているのです。 論文を受動的に読まずに、能動的に読むには上記1~6の順で読むのは有効です。 そもそも私たちが抄読会で皆に配るプリントには、abstractと実験結果を示した図や表くらいしか載せません。実験の条件などは口頭でいいます。英語の勉強会でない限りはそれで十分です。

During compoud infusion, animals received intraperitoneal (IP) injection daily with the thymidine analog bromodeoxyuridine (BrdU, 50 mg/kg) to score birth and survival of proliferating hippocampal neural precursor cells. 辞書を調べて単語の意味だけまず確認しておくと手が付けられるかもしれません。時間がないので回答者は調べていませんが、 compoud infusionの間に、動物はintraperitoneal(iP)注入を毎日受けます。それはthymidineアナログ bromodeoxyuridine (BrdU,50 mg/kg)を注入することで誕生と生存の記録を取るためです。つまり、proliferatingする hippocampal 神経の先行カーソル cellsの生存記録を取るためです。 頭から固まりごと訳してみました。従いまして、文言が重複していますが、何となく不明な英単語を調べれば解るような気がします。これが通常英文を読むときの私の方法です。後ろから決して訳しません。単語がその順番にあるのは理由があるかららです。意味が成り立つ固まり毎に区切って訳すということかもしれません。 後は医学用語に詳しい方にお任せします。

ありがとうございます。 なるほど、頭から固まりごとに訳せばわかりやすいですね。 私は頭から訳しつつも、結局後ろから訳して・・いつも頭が混乱していましたw

    "医学論文訳" Male Wistar rats (Charles River Laboratories) weighing 300?320 g were surgically prepared with silastic catheters in the jugular vein and trained to respond on an ‘active’ lever for food pellets (45 mg; 60 min sessions) under a fixed ratio 5 timeout 20 s (FR5TO20) schedule of reinforcement. Rats then responded for cocaine on the FR5TO20 reinforcement schedule during 1-h daily testing sessions for at least seven consecutive days. Cocaine hydrochloride was dissolved in sterile saline solution (0.9% w/v). Each cocaine infusion earned resulted in the delivery of 0.5 mgkg21 per infusion cocaine (0.1 ml injection volume delivered over 4 s), and initiated a 20-s timeout period signalled by a light cue located above the active lever during which responding on the lever was without consequence. In all cases, a control group of rats were surgically prepared with jugular catheters and trained to respond for food reinforcement as described above, but remained cocaine-naive for the duration of the experiment. To determine the cocaine dose? response curve, the unit dose of cocaine available for self-administration was adjusted upward or downward during 3-h testing sessions every other day between regular 6-h self-administration sessions; for detailed description see ref. 7. Doses of cocaine were tested once, and in the following order: 0.5, 0.0625, 0.25, 0.125 and 0 mgkg21 per infusion.

    "医学論文訳" It is thought to increase sensitivity to the motivational effects of cocaine and associated environmental stimuli, culminating in a loss of control over intake. However, recent findings support a more nuanced view in which cocaine also triggers adaptations in brain reward systems that decrease responsiveness to the drug.

    ”医学論文訳”(暇な人) Armed with these genotype- and region-specific deficits in neuron morphology and electrophysiological activity, we set out to test whether prolonged administration of P7C3 might repair either or both deficits in npas3/ mice. We first verified that P7C3 was capable of enhancing hippocampal neurogenesis in npas3/ mice (Figure S3B). Knowing that formation of the dentate gyrus initiates in the mouse embryo around embryonic day 14 (Stanfield and Cowan, 1988), we sought to expose animals to P7C3 for as extended a period of time as possible in order to give the compound the best possible chance for success. After oral gavage of pregnant female mice, day 14 embryos were recovered, dissected, and processed by acetonitrile: water extraction so that P7C3 levels could be measured in the embryonic brain. Daily administration of 20 mg/kg of P7C3 to pregnant females yielded appreciable levels of the compound in the brain tissue of developing embryos. It was similarly observed that oral administration of the compound to lactating females led to delivery of P7C3 to the brain tissue of weanling pups. In both cases, LC-MS-based quantitation of P7C3 revealed levels of compound accumulation at or above the 1.35 mMlimit required to support adult neurogenesis (Figure 1C). Finally, it was observed that daily IP administration of P7C3 to weaned pups at 20 mg/kg yielded brain levels of P7C3 at or above the level required to enhance adult neurogenesis.
