Previous studies have demonstrated that the leukocyte integrin Mac-1 adheres to several cell surface and soluble ligands including intercellular adhesion molecule-1, fibrinogen, iC3b, and factor X. However, experiments with Mac-1-expressing transfectants, purified Mac-1, and mAbs to Mac-1 indicate the existence of additional ligands. In this paper, we demonstrate a direct interaction between Ma...

This paper presents LB-MAC, a new MAC protocol for asynchronous, duty cycle sensor networks. Different from existing sensor network MAC protocols that usually focus on reducing energy consumption and extending lifetime of individual sensor nodes, LB-MAC aims at prolonging the network lifetime through balancing the nodal lifetime between neighboring sensors. LB-MAC is lightweight and scalable as...

Macrophage inhibitory cytokine 1 (MIC-1), a divergent member of the transforming growth factor beta superfamily, plays a role in the progression of a number of cancers, including breast, gastric, prostate and colorectal carcinomas. Serum MIC-1 levels are elevated in patients with metastatic prostate, breast and colorectal carcinomas. In vitro studies have revealed a cell type-specific role for ...

Little is known to date about the in vitro activity of fluoroquinolones against Borrelia species. Our study aimed at determining the in vitro activities of 15 quinolones against nine isolates of the Borrelia burgdorferi sensu lato complex in addition to one Borrelia valaisiana and one Borrelia bissettii tick isolate. For the determination of MICs, a standardized colorimetric microdilution metho...

In rat basophilic leukemia (RBL) cells and Jurkat T cells, Ca(2+) release-activated Ca(2+) (CRAC) channels open in response to passive Ca(2+) store depletion. Inwardly rectifying CRAC channels admit monovalent cations when external divalent ions are removed. Removal of internal Mg(2+) exposes an outwardly rectifying current (Mg(2+)-inhibited cation [MIC]) that also admits monovalent cations whe...

Mobile wireless sensor networks (MWSNs) have become a foremost solution in many emerging applications both industry and academia. Moreover, considering the mobile node WSN is challenging task to designing efficient communication protocols, specifically at medium access control (MAC) layer. Most of existing protocols consider only for static slow mobility. To meet with future MIoT applications, ...

Molecules that target quorum sensing and biofilm inhibition are useful antimicrobials. In this regard, a new diarylhydrazone was synthesized characterized using infrared, high-resolution mass spectrometry nuclear magnetic resonance experiments as N-[( E)-4-bromo-2,5-diheptyloxybenzylideneamino]-2,4-dinitroaniline (BHBANA). Minimal inhibitory concentrations (MICs) vary from 0.625 to 2.5 mg mL −1...
