人Alpha-2-巨球蛋白（humanalpha-2-macroglobulin，简称hA2M）是一种重要的广谱抑制小蛋白酶的大型糖蛋白（四聚体，分子量720KD），在人体血液中含量丰富。hA2M可以抑制几乎所有种类的小蛋白酶（分子量在80KD以下），以防止它们在血液中过量存在。同时，hA2M也是人身体内最“多才多艺”的蛋白之一，比如hA2M可以调节多种免疫细胞的功能，影响中性粒细胞的迁移和粘附并...
An MspI PCR-RFLP detecting a single nucleotide polymorphism at alpha-lactalbumin gene in goat
goat alpha-lactalbumin gene polymorphism Single Nucleotide Polymorphism (SNP) PCR-RFLP
2015/6/4
Alpha-lactalbumin (α-LA, LALBA) was strongly correlated with the nutritional value and the functional properties of whey and whey products. However, there are not many studies of goat LALBA gene and i...
Effects of Dietary L-carnosine and Alpha-lipoic Acid on Growth Performance, Blood Thyroid Hormones and Lipid Profiles in Finishing Pigs
Alpha-lipoic Acid L-carnosine Thyroid Hormones Lipid Profiles Finishing Pigs
2016/5/19
The present study was conducted to determine the effects of L-carnosine (LC) and/or alpha-lipoic acid (ALA) supplementation on growth performance, blood thyroid hormones and lipid profiles in finishin...
Simulations of damped Ly alpha and Lyman limit absorbers in different cosmologies: Implications for structure formation at high redshift
formation large scale structure of the Universe
2014/12/26
We use hydrodynamic cosmological simulations to study damped Lyα (DLA) and Lyman limit (LL) absorption at redshifts z = 2-4 in five variants of the cold dark matter scenario: COBE-normalized (CCDM), c...
We examine the cooling radiation from forming galaxies in hydrodynamic simulations of the LCDM model (cold dark matter with a cosmological constant), focusing on the Lyα line luminosities of high-reds...
Comparing simulations and observations of the Ly alpha forest. I. Methodology
data analysis N-body simulations
2014/12/26
We describe techniques for comparing spectra extracted from cosmological simulations and observational data, using the same methodology to link Lyα properties derived from the simulations with propert...
Lyman Alpha Absorber Correlations and the Bias of the Lyman Alpha Forest
BIAS THE Lyman Alpha Forest
2014/12/26
Lyman alpha absorber correlations contain information about the underlying density distribution associated with a particular class of absorbers. As such, they provide an opportunity to independently m...
Toward a precise measurement of matter clustering: Ly alpha forest data at redshifts 2-4
absorption lines large scale structure of universe
2014/12/26
We measure the filling factor, correlation function, and power spectrum of transmitted flux in a large sample of Lyα forest spectra, comprised of 30 Keck HIRES spectra and 23 Keck LRIS spectra. We inf...
We review recent developments in the theory of the Ly forest and their implications for the role of the forest as a test of cosmological models. Simulations predict a relatively tight correlation betw...
We use hydrodynamic cosmological simulations to predict correlations between Lyα forest absorption and the galaxy distribution at redshift z 3. The probability distribution function (PDF) of Lyα flux ...
We analyse the flux power spectrum and its covariance using simulated Lyα forests. We find that pseudo-hydro techniques are good approximations of hydrodynamical simulations at high redshift. However,...
Measuring the halo mass of z similar to 3 damped Ly alpha absorbers from the absorber-galaxy cross-correlation
high-redshift absorption lines
2014/12/24
We test the reliability of a method to measure the mean halo mass of absorption-line systems such as damped Lyα absorbers (DLAs). The method is based on measuring the ratio of the cross-correlation be...
Spatial correlation between submillimetre and Lyman-alpha galaxies in the SSA 22 protocluster
submillimetre Lyman-alpha galaxies
2014/12/23
Lyman- emitters are thought to be young, low-mass galaxies with ages of 108 yr (refs 1, 2). An overdensity of them in one region of the sky (the SSA 22 field) traces out a filamentary structure in the...
COMPARISON OF H alpha AND UV STAR FORMATION RATES IN THE LOCAL VOLUME: SYSTEMATIC DISCREPANCIES FOR DWARF GALAXIES
evolution dwarf
2014/12/23
Using a complete sample of ~300 star-forming galaxies within 11 Mpc of the Milky Way, we evaluate the consistency between star formation rates (SFRs) inferred from the far ultraviolet (FUV) non-ionizi...
DUST-CORRECTED STAR FORMATION RATES OF GALAXIES. I. COMBINATIONS OF H alpha AND INFRARED TRACERS
ISM evolution
2014/12/22
We combine Hα emission-line and infrared (IR) continuum measurements of two samples of nearby galaxies to derive dust attenuation-corrected star formation rates (SFRs). We use a simple energy balance ...
