Chitosan functionalized with 2-mercaptobenzimidazole (2-MBI) (i.e. [email protected]) shows high sorption capacity (i.e., 1.28 mmol MB g−1) for methylene blue (MB) (at pH close to 9.3). Sorption is weakly decreased (by less than 25%) by NaCl concentration (up 45 g L−1). The (slightly endothermic) fitted the Langmuir equation. kinetic profile pseudo-first order rate equation (PFORE): equilibrium...

Objective(s): The Janus kinase-signal transducers and activators of transcription signaling pathway (JAK/STAT pathway) play an important role in proliferation of breast cancer cells. Previous data showed that inhibition of STAT3 suppresses the growth of breast cancer cells, but the associated mechanisms are not well understood. This study aims to investigate the effect and associated mechanisms...

background: l-carnitine has been demonstrated to confer cardiac protection against ischemia reperfusion injury in animals. this study evaluates the effects of l-carnitine administration on cardiac biomarkers after coronary artery bypass graft (cabg) surgery. methods: one hundred thirty-four patients undergoing elective cabg surgery, without a history of myocardial ischemia or previous l-carniti...

objective(s): this paper aims to investigate synergistic inhibition of polysaccharide from sepia esculenta ink (sip), a newly isolated marine polysaccharide in our laboratory, on breast cancer mda-mb-231 cells exposed to cisplatin. materials and methods: cell viability of mda-mb-231 cells was determined by cck 8 assay. median-effect concentration was analyzed using chou-talalay method that was ...

We present a universal democratic Lagrangian for the bosonic sector of ten-dimensional type II supergravities, treating "electric" and "magnetic" potentials all RR fields on equal footing. For IIB, this includes five-form whose self-duality equation is derived from Lagrangian. also an alternative form action with manifest $SL(2,\mb R)$ symmetry.

This paper investigates the Multi-band OFDM (MB-OFDM) based physical (PHY) layer proposal for IEEE 802.15.3a working group on short-range high data-rate Ultra-wide-Band (UWB) communications. An overview of the MB-OFDM PHY layer architecture with its various parameters is presented and the optimal choice of critical parameters is discussed. Next, we derive the theoretical un-coded Bit Error Rate...
