Study shows limitations of method for determining protein structure（图）
Study limitation determine protein structure
2019/10/17
A new study by chemists at the University of Arkansas shows that X-ray crystallography, the standard method for determining the structure of proteins, may provide inaccurate information about a critic...
Determining the protein needs of “older” persons one meal at a time
protein requirement older persons
2018/11/12
The determination of protein requirements (need) and “optimal” protein intakes (greater than need but beneficial to health) is complex and currently, insofar as older persons are concerned, without co...
A Test of the Role of Electrostatic Interactions in Determining the CO Stretch Frequency in Carbonmonoxymyoglobin
Electrochemistry Escherichia coli Humans Mutagenesis, Site-Directed Myoglobin Point Mutation Protein Conformation Recombinant Proteins Spectroscopy, Fourier Transform Infrared Vibration
2016/5/23
The vibrational frequency of CO bound to myoglobin can be varied by up to 60 cm-1 by making site-specific mutations in the distal pocket. These changes may result from specific chemical interactions b...
Determining molecular mechanisms of DNA Non-Homologous End Joining proteins
DNA repair non-homologous end joining
2015/5/25
DNA double strand breaks (DSB), particularly those induced by ionizing radiation (IR) are complex lesions and if not repaired, these breaks can lead to genomic instability, chromosomal abnormalities a...
The roles of productivity and ecosystem size in determining food chain length in tropical terrestrial ecosystems
ecosystem size food chain length food web structure islands
2015/11/13
Many different drivers, including productivity, ecosystem size, and disturbance,
have been considered to explain natural variation in the length of food chains. Much remains
unknown about the role o...
Determining of the Effect of Lysine:calorie Ratio on Growth Performance and Blood Urea Nitrogen of Growing Barrows and Gilts in Hot Season and Cool Season in a Commercial Environment
Blood Urea Nitrogen Growing Pigs Growth Performance Lysine:calorie Ratio
2016/5/11
Two experiments were conducted to determine an optimum Lys:calorie ratio (g of total dietary Lys/Mcal of DE) for growing barrows and gilts in cool and hot seasons in a commercial environment. In Exp. ...
Carcass Traits Determining Quality and Yield Grades of Hanwoo Steers
Quality Grade Yield Grade Slaughter Weight Hanwoo
2016/4/13
A group of Hanwoo (Korean cattle) steers (n=14,386) was sampled from a commercial abattoir located in Seoul over one year period (spring, summer, autumn and winter) and their carcass traits were colle...
A Computer Programme for Determining Habitat Preference Based on Dung Frequencies of Some Herbivore Mammals
Dung Counts Red deer Hare Wild boar Habitat selection Component combination Computer programme
2010/3/31
The classic approach for habitat preference of big games is to compare dung density in two different site such as in two habitat types and aspects, or in two altitute or slope classes. Whereas, animal...
Competition Between Strains With Autosomal and Standard Sex-determining Mechanisms in the Housefly (Muscidae)
Musca domestica L. Competition cytogenetics autosomal sex-determining mechanism evolution
2010/3/31
Experimental cages started with a mixture of flies at three different ratios (1:9, 5:5, 9:1) from populations having heterosomal and autosomal sex-determining mechanisms were cytogenetically examined ...
Two New Sex Determining Factors ( M V , F D ) in Housefly, (Musca domestica) Populations in Turkey
Musca domestica sex determination M factor F D factor
2010/3/31
In most strains of the common housefly, Musca domestica, sex is genetically determined by the presence or absence of a Y chromosome with a dominant male determining factor, M. Standard trains have an ...
