Nutrition has a significant effect on reproduction and lactation in Ruminant. Supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. Negative energy balance may sometimes result in reduced livestock production an...

The colony-stimulating factors (CSFs) form a family of hemopoietic growth factors controlling the survival, proliferation and differentiation of hemopoietic progenitor cells as well as the functional activities of the mature cells in the tissues [1]. In the mouse, four distinct CSFs controlling granulocyte and macrophage production have been identified, purified and, in two cases, molecularly c...

Abstract. The continuous increasing of Earth observations benefits geosciences and seismicity study but increases greatly the difficulties in understanding discriminating multiple source data. Although lithosphere–coversphere–atmosphere-ionosphere (LCAI) coupling paradigm deviation–time–space (DTS) criterion were presented for better searching potential seismic anomalies from observations, stri...

This study investigated the role of three genes comprising part of the operon which encodes CS5 pili from enterotoxigenic Escherichia coli. In-frame gene deletions were constructed, and the effects on biogenesis of the pili were examined. A deletion in csfB abolished CsfA major subunit accumulation in the periplasm, which could be restored by trans-complementation with a complete copy of the cs...

We have sequenced the entire region of DNA required for the biosynthesis of CS5 pili from enterotoxigenic Escherichia coli O115:H40 downstream of the major subunit gene, designated csfA (for coli surface factor five A). Five more open reading frames (ORFs) (csfB, csfC, csfE, csfF, and csfD) which are transcribed in the same direction as the major subunit and are flanked by a number of insertion...
