Purinergic signaling involves the activation of cell surface P1 and P2 receptors by extracellular nucleosides and nucleotides such as adenosine and adenosine triphosphate (ATP), respectively. P2 receptors comprise P2X and P2Y receptors, and have well-established roles in leukocyte and platelet biology. Emerging evidence indicates important roles for these receptors in red blood cells. P2 recept...

The temperature-sensitive mutant CRT46 of Escherichia coli K12 is unable to initiate new rounds of DNA replication at 42 degrees C. Mutants of bacteriophage P2 have been isolated, which, in the prophage state, allow mutant CRT46 to grow at 42 degrees C. The lysogenic bacteria that grow at 42 degrees C are apparently replicating under the control of prophage P2, which substitutes for the bacteri...

The bifurcations of generic heteroclinic loop with one nonhyperbolic equilibrium p1 and one hyperbolic saddle p2 are investigated, where p1 is assumed to undergo transcritical bifurcation. Firstly, we discuss bifurcations of heteroclinic loop when transcritical bifurcation does not happen, the persistence of heteroclinic loop, the existence of homoclinic loop connecting p1 (resp. p2) and the co...

We studied the dephosphorylation pathway for Ins(1,3,4)P3 (inositol 1,3,4-trisphosphate) by liver homogenates and soluble and particulate subfractions incubated in media resembling physiological ionic strength and pH. Ins(1,3,4)P3 was dephosphorylated to two InsP2 (inositol bisphosphate) isomers, one of which is Ins(3,4)P2 [Shears, Parry, Tang, Irvine, Michell & Kirk (1987) Biochem. J. 246, 139...

The reaction: glycerate-1,3-P2 PLUS GLUCOSE-1-P YIELDS TO GLUCOSE-1,6-P2 plus glycerate-P is catalyzed by a distinct enzyme of mouse brain. A divalent metal requirement was shown when the enzyme was treated with imidazole and EDTA. Mg2+, Mn2+, Ca2+, Zn2+, Ni2+, Co2+, and Cd2+ were quite effective cofactors. The enzyme, in better than 50 percent yield, has been purified away from 99 percent of t...

A field study was conducted during Kharif 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P), India. The soil texture the experimental plot sandy loam, with a pH 7.8, low organic carbon (0.35 percent), available N (243 kg/ha), P (20.10 and K (105 kg/ha). Study laid out in Randomized Block Design, nine treatments consists viz., 1 : (RDF 50% + FYM 5t/ha) +P1 -3%, 2 +P2 - ...

Sodium-ion batteries are regarded as a substitution for lithium-ion its abundant resources, wide distribution, low cost, etc. The P2-layered sodium transition metal oxides (P2-NaxTMO2) have attracted extensive attention due to their high rate and cycling properties. However, P2-NaxTMO2 often undergoes structural transformations when exposed in ambient air, which restricts practical applications...

In this paper, a certain new connectedness of L-fuzzy subsets inL-topological spaces is introduced and studied by means of preclosed sets. Itpreserves some fundamental properties of connected set in general topology.Especially the famous K. Fan’s Theorem holds.

When we know the subjective probabilities (degrees of belief) p1 and p2 of two statements S1 and S2 , and we have no information about the relationship between these statements, then the probability of S1 & S2 can take any value from the interval max(p1 + p2 ? 1; 0); min(p1; p2)]. If we must select a single number from this interval, the natural idea is to take its midpoint. The corresponding \...

A property of graphs is any class of graphs closed under isomorphism. Let P1,P2, . . . ,Pn be properties of graphs. A graph G is (P1,P2, . . . ,Pn)-partitionable if the vertex set V (G) can be partitioned into n sets, {V1, V2, . . . , Vn}, such that for each i = 1, 2, . . . , n, the graph G[Vi] ∈ Pi. We write P1◦P2◦ · · · ◦Pn for the property of all graphs which have a (P1,P2, . . . ,Pn)-partit...
