查询词典 G-force

However, there are many moreA/T→G/C changes than G/C→A/T in a single arm, which would lead to an increasing trend in GC content and suggest that the composition is not at equilibrium.

然而，在每个臂上，A/T→G/C 的突变数目却大于G/C→A/T的，这表明回文序列的成分并没有达到平衡，并且GC含量有上升的趋势。

As investigated, the shape of the fruit was mainly rotundity, and the color of the fruit were red, black, yellow, mauve. Variation coefficient of mineral elements, which revealed wider variation range and rich genetic diversity. Among them, Fe, the content and the variation coefficient of which was the highest(2.12 mg·100g-1 and 26.99％), it has large potential for futher selection. Ripe fruit of 12 wild myrobalan plum seedlings were analyzed using head space-solid phase microextraction and gas chromatography-mass spectrometry. The results showed considerable genetic variations in these aspects: The total content of volatile components, the classes and contents of each compounds classes, the segregation ratio, and content of main components. There were 83 compounds in total belonging to 6 classes detected in 12 wild myrobalan plum seedlings, including esters, alcohols, ketones, aldehydes, heterocycle and Hydrocarbons. Among them, Formic acid, hexyl ester, the content of which was the highest(4.33 μg·g-1),was important character impact odors.

It is shown that every minimum geodetic set of a graph does not contain its cut-vertices, and if G is a block graph with n≥3 vertices and k≥1 cut-vertices,then g=n-k.

图的每个最小测地集都不包括它的割点，如果图G是一个有n≥3个顶点，k≥1个割点的块图，那么g=n-k。

A549 cell line was stimulated with LPS (10 μg/mL) and then treated with Rs504393 (10 μg/mL) for 6 hours. ALI model was established with intranasal administration of LPS (5 mg/kg) in C57BL/6J mice. RS504393 (5 mg/kg) was administered 30 min before LPS dripped nasally. IL-8, IL-1β, plasminogen activator inhibitor-1, monocyte chemoattractant protein-2, and the expressions of CCR1 and CCR2b were studied by using Realtime-RT-PCR, ELISA and cyto-flowmetry.

Lipids are an energy-dense source of fuel calories (~~9kcal/g) compared with proteins and carbohydrates(both ~~4 kcal/g).It is generally recommended in clinical practice that the lipid supply should provide 15-30%of the total calorie intake,or 30-50%of nonprotein calories.

与蛋白和碳水化合物相比，脂肪乳脂质的能量密度更大(≈9 kcal/g比≈4 kcal/g)，所以在临床上普遍推荐脂质供能应占总热量的15-30%，或非蛋白热量的30-50%。

Methods We adopted four methods that single cpidural block anesthesia or narcotics analgesies were injected into subarachnoid space and epidural space or single narcotics was injected into subarachnoid space (group C fentanly 25μg;group D fentanly 20μg) to study analgesia birth for 130 nullipara women. The analgesia efficacy, side effect, birth time md mode,postpartum haemorrhage and the condition of the fetus and the newborn were compared.
