リバーでのトリアシルグリセロール(TAG)合成と分泌は栄養の利用可能性と密接に関連しています。

このQ&Aのポイント
  • 食事後、肝臓での脂肪酸によるTAGの形成は、循環する遊離脂肪酸(FFA)の減少によって大幅に減少します。
  • FFAによるエステル化と酸化が食事後に減少しても、VLDL-TAGの分泌は維持され、末梢脂質の供給と代謝をサポートします。
  • L-Raptor-KOまたは対照の肝細胞研究のための胆管細胞において、4〜9匹のマウスごとに胆管細胞を分離し、技術的な再現をプールしました。

次の文章の日本語訳お願いします。 (1)Liver triacylglycerol (TAG) synthesis and secretion are closely linked to nutrient availability. After a meal, hepatic TAG formation from fatty acids is decreased, largely due to a reduction in circulating free fatty acids (FFA). この文章のcirculating free fatty acids の部分 (2)Despite the postprandial decrease in FFA-driven esterification and oxidation, VLDL-TAG secretion is maintained to support peripheral lipid delivery and metabolism. この文章の FFA-driven の部分 (3)Secreted TAG. n = 3. For hepatocyte studies in L-Raptor–KO or control, hepatocytes from 4 to 9 mice per group were isolated and technical replicates pooled. この文章の technical replicates pooledの部分 (4)While CCTα mRNA levels were equivalent between both genotypes (Figure 5D), protein levels were diminished in liver from the L-Raptor–KO mice to an extent commensurate with the reduction in enzyme activity, suggesting regulation of CCTα stability or translation by mTORC1 at a posttranscriptional site (Figure 5E). (5)Restoration of PC synthesis normalizes hepatic triglycerides and VLDL-TAG secretion in L-Raptor–KO. (6)We reasoned that if mTORC1 regulates TAG secretion by promoting PC biosynthesis, restoration of PC synthesis would rescue the TAG secretion defect induced by loss of raptor. ご回答よろしくお願いします。

1)循環している遊離脂肪酸(つまり血中遊離脂肪酸) 2)FFAはfree fatty acidのことでしょうね。遊離脂肪酸によって駆動される(つまり遊離脂肪酸によって進行する) 3)technical replicateは同一の試料から複数回同じ操作でデータを取ることです。実験操作によるブレを反映します。これで得られた複数のデータをプールして(つまり取りまとめて)、一個のデータにしたということ。ちなみに、これに対してbiological replicateは、同じ処理群の異なる生物試料(個体、あるいは別の培養皿など)からそれぞれデータを取ることです。個体差など生物が持っているバラツキを反映します。 えっ、あと全訳を要求してるの? 文法的には大して難しくないぞ。

    In The World Crisis, Winston Churchill used figures from French parliamentary records of 1920, to give French casualties from 5 August to 5 September 1914 of 329,000 killed, wounded and missing, German casualties from August to November of 677,440 men and British casualties in August and September of 29,598 men. By the end of August, the French Army had suffered 75,000 dead, of whom 27,000 were killed on 22 August. French casualties for the first month of the war were 260,000, of which 140,000 occurred during the last four days of the Battle of the Frontiers. In 2009, Herwig recorded that the casualties in the 6th Army in August were 34,598, with 11,476 men killed and 28,957 in September with 6,687 men killed. The 7th Army had 32,054 casualties in August, with 10,328 men killed and 31,887 casualties in September with 10,384 men killed. In the 1st Army in August there were 19,980 casualties including 2,863 men killed and in the 2nd Army 26,222 casualties. In the last ten days of August, the 1st Army had 9,644 casualties and the 2nd Army had losses of 15,693 men. Herwig wrote that the French army did not publish formal casualty lists but that the Official History Les armées françaises dans la grande guerre gave losses of 206,515 men for August and 213,445 for September. During the battle, French casualties were c. 260,000 men, of whom c. 75,000 men were killed.

    It was agreed in the London Convention of 16 January, that the French assault on the Aisne would begin in mid-April and that the British would make a diversionary attack in the Arras sector approximately one week prior. Three armies of Field Marshal Sir Douglas Haig, the commander of the British Expeditionary Force (BEF) were in the Arras sector, the Fifth Army (General Hubert Gough) in the south, the Third Army (General Edmund Allenby) in the centre and the First Army (General Henry Horne) in the north and the plan was devised by Allenby. In December 1916, the training manual SS 135 replaced SS 109 of 8 May 1916 and marked a significant step in the evolution of the British Expeditionary Force (BEF) into a homogeneous force, well adapted to its role on the Western Front. The duties of army, corps and divisions in planning attacks were standardised. Armies were to devise the plan and the principles of the artillery component. Corps were to allot tasks to divisions, which would then select objectives and devise infantry plans subject to corps approval.

    Joffre set 14 August as the date when the First and Second armies were to invade Lorraine between Toul and Épinal, south of the German fortified area of Metz-Thionville. The First Army was to attack in the south with four corps, towards Sarrebourg 60 kilometres (37 mi) east of Nancy and Donon 25 kilometres (16 mi) south of Sarrebourg. Passes in the Vosges to the south of Donon were to be captured before the main advance began. The Second Army was to attack towards Morhange 45 kilometres (28 mi) north-east of Nancy, with two corps north of the First Army and three advancing successively behind the left flank of the corps to the south, to counter a German attack from Metz. The French offensive was complicated by the two armies diverging as they advanced, on difficult terrain particularly in the south, the combined fronts eventually being 150 kilometres (93 mi) wide. The advances of the First and Second armies were to attract German forces towards the south, while a French manoeuvre took place in Belgium and Luxembourg, to pierce a weak point in the German deployment and then destroy the main German armies.

    All the captured arms and equipment were made in Germany, and the camel-pack machine gun company's equipment had been especially designed for desert warfare. Many of the rifles were of the latest pattern and made of rustless steel. Murray estimated the total German and Ottoman casualties at about 9,000, while a German estimate put the loss at one third of the force (5,500 to 6,000), which seems low considering the number of prisoners. The tactics employed by the Anzac Mounted Division were to prove effective throughout the coming campaigns in the Sinai and in the Levant (also known at the time as Palestine).

    Comparison of a system suffering from western-related conditions (right, in red) and a system with amelioration of western-related conditions (left, in orange). One aspect of a western lifestyle is the higher intake of ω-6 PUFA (depicted as FFA), this enhances the formation of chylomicrons allowing the translocation of LPS, these then activate basolateral TLR which initiates a pro-inflammatory response, one overall consequence is the alteration of the gut epithelium and its permeability (depicted as deteriorated epithelium and compromised tight junctions), exacerbating inflammation by allowing the translocation of more LPS, pro-inflammatory cytokines, FFA, among other luminal compounds (1).

    Under the papacies of Calixtus II, Honorius II, Eugenius III and Innocent II smaller scale crusading continued around the Crusader States in the early 12th century. There were campaigns by Fulk V of Anjou between 1120 and 1129, the Venetians in 1122–24, Conrad III of Germany in 1124 and the Knights Templar were established. The period saw the innovation of granting indulgences to those who opposed papal enemies that marked the beginning of politically motivated crusades. The loss of Aleppo in 1128 and Edessa (Urfa) in 1144 to Imad ad-Din Zengi, governor of Mosul led to preaching for what subsequently became known as the Second Crusade. King Louis VII and Conrad III led armies from France and Germany to Jerusalem and also Damascus without winning any major victories. Bernard of Clairvaux, who had encouraged the Second Crusade in his preaching, was upset with the violence and slaughter directed towards the Jewish population of the Rhineland.

    Joffre had accepted claims by Castelnau, that up to 6.2–7.5 mi (10–12 km) of ground could be gained in twenty-four hours and rejected a methodical battle, which ... would entail a month of combat, with a maximum expenditure of ammunition; at what point would we be able to declare ourselves ready for attack? — Joseph Joffre Ammunition necessary for a methodical battle did not exist and the opportunity to attack the Germans, when so many divisions had been moved to the eastern front, could not be wasted. The offensive had been fought with unprecedented refinements of tactics and supply. Amendments to Note 5779 were suggested, to cover items like the use of 23,000 hand grenades in two days by the 53rd Division and the importance of attention to detail; Pétain of XXXIII Corps had ensured accurate preparatory bombardments and the tactical reflections written by Pétain were added to the thinking in Note 5779. The ideal characteristics of a network of jumping-off trenches and the time and labour necessary to build it were laid down, so that troops could advance simultaneously and reserve troops could be protected as they moved forward. Pétain wrote the plan for the Groupe d'armées du Centre, for the offensive of 25 September and his views were circulated through the French and British armies. The autumn offensive was fought as a breakthrough attempt, with changes to avoid the mistakes made in Artois in May and had significant tactical success but did not achieve a breakthrough, which led to the adoption of limited attacks in 1916. Krause wrote that the formulation Note 5779 showed that the French command system, was staffed by men who tried to improve the performance of the army and contradicts claims by Gudmundsson, that the Allied armies were too centralised to adapt. Lessons had been collected, analysed and distributed in a manner which combined top-down and bottom-up processes. A flaw in Note 5779, was persistence with a concept of rapid breakthrough, even after many soldiers considered that the war had become a siege and that none of the French offensives of 1915, had been intended to return to mobile warfare. Changes made to the plan for the Second Battle of Artois, had been intended to secure the capture Vimy Ridge as a jumping-off point, rather than to achieve a breakthrough and return to mobile warfare. In the autumn offensive which began on 25 September, with the Third Battle of Artois, Battle of Loos and the Second Battle of Champagne, the strategy was intended to make the Noyon salient untenable and regain a large portion of the occupied territories. Tactics used in the battles of May and June were revised and the creeping barrage became a standard method in all the Western Front armies.

    The Sykes–Picot Agreement /ˈsaɪks pi.ko/, officially known as the Asia Minor Agreement, was a secret agreement between the United Kingdom of Great Britain and Ireland and the French Third Republic, with the assent of the Russian Empire, defining their proposed spheres of influence and control in Southwestern Asia should the Triple Entente succeed in defeating the Ottoman Empire during World War I. The negotiation of the treaty occurred between November 1915 and March 1916, the agreement was signed on 16 May 1916, and was exposed to the public in Izvestia and Pravda on 23 November 1917 and in the British Guardian on November 26, 1917. The Agreement is considered to have shaped the region, defining the borders of Iraq and Syria and leading to the current conflict between Israelis and Palestinians.

    Lieutenant-Colonel Freeth (with 18 men) and Major Thompson (with 170 men) held onto the summits of Latema and Reata. Tighe was unable to follow the events of the battle and fearing heavy casualties and possible counterattack, ordered a withdrawal at 4:20am. However, as patrols reached the Nek to order the retreat, they found Freeth and Thompson in command of the heights and the Germans in full retreat. Smuts ordered the 8th South African Regiment to the field in order to consolidate the position. Following the battle the Germans retreated to Lake Kahe in order to prepare further defences. Freeth and Thompson were both awarded the Distinguished Service Order for their decisive roles in the engagement. General Tighe retained his command of the 2nd Division as Mallesons replacement.
