Abstract MicroRNAs (miRNAs) are essential nonprotein-coding genes. In a range of organisms, miRNAs has been reported to play an role in regulating gene expressions at post-transcriptional level. They participate most the stress responsive processes plants. Drought is ultimate abiotic that affects crop production. Therefore understanding drought responses improve production agricultural crops. T...

Ruminants are major contributorsof methane (CH4) production. Serious global efforts are required to reduce CH4 produced through their digestive tract, which isgenerally termed as enteric methane production (e.m.p). Feeding diets containing nitrates and/or sulphates could be used to reduce e.m.p. The study was conducted to evaluate the influence of varying levels of sodium nitrate (SN) with or w...

Thyroglobulin may be defined as the iodine-containing protein of the thyroid gland which has a sedimentation coefficient of 4o.w = 19 S, an electrophoretic mobility at pH 8.6 of approximately 5 x 10F5 cm2 volt-l set-1, and a steep salting out curve at about 38% ammonium sulfate saturation at neutral pH (1). Although other iodoproteins, both soluble in neutral salt and attached to cell particles...

We have used Mössbauer emission spectroscopy to study an oxygenated heme complex, produced in a frozen solution by nuclear decay from the isomorphous (57)Co-labeled compound. The Mössbauer parameters agree with those obtained by Mössbauer absorption spectroscopy of oxyhemoglobin. Thus, a nonprotein environment for iron can duplicate the unique oxyhemoglobin Mössbauer spectrum. The electronic st...

Several possible mechanisms of resistance to alkylating agents have been posed and discussed on the basis of presently available experimental data. The two mechanisms that appear to be most plausible are altered cell permeability toward the agents and deactivation of the agents by combination with nonprotein sulfhydnyl groups. These two mechanisms might function simultaneously and might contrib...

The great importance of legume hay is recognized by everyone interested in livestock production. Because of this importance, it is highly desirable to obtain data on the nutritive value of the proteins in these hays when they are fed alone and when fed in combination with the protein of corn and other farm-grown grains. It is apparent that the great value of legume hays in stock feeding is larg...

Before the work of Costantino, the erythrocyte was considered to be impermeable to ammo acids (1, 2). Costantino observed, however, a higher level in the red blood cell than in the serum of groups titratable in the presence of formaldehyde (3). He was also able to demonstrate by this method uptake by red cells in vitro of glycine, asparagine, and the mixture of amino acids contained in a casein...
