By binding to adjacent subsites in its 21 base-pair operator, Arc represses transcription from two divergent promoters, Pant and Pmnt, in the immunity I operon of bacteriophage P22. Arc dimers bind to each subsite with nanomolar affinities and interact through protein-protein interactions to stabilize binding further. Here, we show that an Arc dimer bound to a single subsite reduces the rate of...

In fetus, while minor degree of hydrocephalus often goes undetected, severe cases of obstructive variety present with the following features: 1 .the head is felt larger, globular and softer than the normal head 2.the head is high up and difficult to push down into pelvis 3.fetal heart sound is situated high up above the umbilicus 4.internal examination during labor may reveal widening of suture...

Vocal interactions, such as call exchanges or choruses, are common behaviours in animals and their function has been often linked to social bonding. In this study, I examined the relationship between two types of vocal behaviour common in chimpanzees, pant hoot chorusing and food calling, and social bonds between males. The results of this study, which was conducted on the Kanyawara community o...

The adenylation (A) domain of the Yersinia pestis nonribosomal peptide synthetase that biosynthesizes the siderophore yersiniabactin (Ybt) activates three molecules of L-cysteine and covalently aminoacylates the phosphopantetheinyl (P-pant) thiols on three peptidyl carrier protein (PCP) domains embedded in the two synthetase subunits, two in cis (PCP1, PCP2) in subunit HMWP2 and one in trans (P...

In this paper we show that the result of Pant Vyomesh [6] is not tenable and prove it when in a more general setting.

Two fields experiments were achieved during the Nili season of 2017 and 2018 at Experimental Farm Faculty Agriculture, Fayoum University, Gornorate to investigate effect soil humic acid rates (0, 25, 50 75 kg fed-1 ), foliar zinc oxide nanoparticles concentrations (50 100 ppm) on tomato hybrid growth productivity. The interaction between kg/fad. spray with ppm increased leaf area / plant canopy...

Audience effects are key in studies of animal social cognition and typically investigated during directed interactions. Male chimpanzees, Pan troglodytes, regularly perform aggressive displays the presence others, often targeting a specific group member, combine this agonistic behaviour with acoustic signals. Here, we were interested whether production structure pant hoots, long-distance signal...
