Eclipta prostrata (L.) L. belonging to the Astearaceae family has been long used worldwide by various communities as a traditional medicine. We studied antibacterial activity of different extracts from against Aeromonas hydrophila, dhakensis, and Vibrio parahaemolyticus . The processing this extract using repeated column thin layer chromatographic techniques resulted in isolation three compound...

We develop a randomized approximation algorithm for the size of set union problem |A1∪A2∪...∪Am|, which is given list sets A1,...,Am with approximate mi Ai mi∈((1−βL)|Ai|, (1+βR)|Ai|), and biased random generators probability Prob(x=RandomElement(Ai))∈[1−αL|Ai|,1+αR|Ai|] each input element x∈Ai, where i=1,2,...,m αL,αR,βL,βR∈(0,1). The ratio |A1∪A2∪...∪Am| in range [(1−ϵ)(1−αL)(1−βL),(1+ϵ)(1+αR...

It is known that the branching time language ACTL and the linear time language ∀LTL of universally quantified formulae of LTL have incomparable expressive powers, i.e., Sem(ACTL) and Sem(∀LTL) are incomparable sets. Within a standard abstract interpretation framework, ACTL can be viewed as an abstract interpretation LTL∀ of LTL where the universal path quantifier ∀ abstracts each linear tempora...

The accepted model for the interaction of α and β integrins in the transmembrane (TM) domain is based on the pair αIIbβ3. This involves the so-called outer and inner membrane association clasps (OMC and IMC, respectively). In the α chain, the OMC involves a GxxxG-like motif, whereas in the IMC a conserved juxtamembrane GFFKR motif experiences a backbone reversal that partially fills the void ge...

We develop an randomized approximation algorithm for the size of set union problem |A1 ∪ A2 ∪ ... ∪ Am|, which given a list of sets A1, ..., Am with approximate set size mi for Ai with mi ∈ ((1− βL)|Ai|, (1 + βR)|Ai|), and biased random generators with Prob(x = RandomElement(Ai)) ∈ [ 1−αL |Ai| , 1+αR |Ai| ] for each input set Ai and element x ∈ Ai, where i = 1, 2, ..., m. The approximation rati...

The tris(pentafluoroethyl)silanol, Si(C2F5)3OH, flashes out of the shadows silanol derivatives in cover image, paving way to its disiloxane and disilanolate. Oxidation tris(pentafluoroethyl)silane, Si(C2F5)3H, with NO2 provides which readily condenses (C2F5)3SiOSi(C2F5)3. Deprotonation situ generated Si(C2F5)3OH yields disilanolate [{Si(C2F5)3O}2]2− underlining formally Lewis amphoteric charact...

Integrins play important roles in regulating a diverse array of cellular functions crucial to the initiation, progression, and metastasis of tumors. Previous studies have shown that a majority of integrins are folded by the endoplasmic reticulum chaperone gp96. Here, we demonstrate that the dimerization of integrin αL and β2 is highly dependent on gp96. The αI domain (AID), a ligand binding dom...

Notable biological activities including brains protective have made carbohydrate esters as a topic of great interest over the past several decades. In this context, unimolecular treatment methyl α-L-rhamnopyranoside (3) with dibutyltin oxide gave corresponding 2,3-O-(dibutylstannylene) derivative which was then allowed to react 3-chlorobenzoyl chloride. The reaction regioselectively furnished 3...
