Oxidative desulfurization of fuels using alcohol-based DESs.

The presence of sulfur-containing compounds in fuel oil has become a major global issue due to their release of toxic sulfur dioxide. Hydrodesulfurization is a commonly used method for removing sulfur from fuel. However, new desulfurization techniques have been developed recently as hydrodesulfurization (HDS) is ineffective in removing refractory sulfur, e.

TNF-α synergises with IFN-γ to induce caspase-8-JAK1/2-STAT1-dependent death of intestinal epithelial cells.

Rewiring of host cytokine networks is a key feature of inflammatory bowel diseases (IBD) such as Crohn's disease (CD). Th1-type cytokines-IFN-γ and TNF-α-occupy critical nodes within these networks and both are associated with disruption of gut epithelial barrier function. This may be due to their ability to synergistically trigger the death of intestinal epithelial cells (IECs) via largely unknown mechanisms.

The protection mechanism offered by Heterophragma adenophyllum extract against Fe-C steel dissolution at low pH: Computational, statistical and electrochemical investigations.

An ethanolic extract of Heterophragma adenophyllum (HA) was investigated as a corrosion inhibitor for Fe-C steel in hydrochloric acid. The inhibition effect of the HA extract was examined using weight deterioration, electrochemical impedance spectroscopy (EIS) and polarization techniques. EIS showed enhanced charge transfer resistance with a maximum protection value of ~96% at 600 ppm concentration.

Effect of anaesthesia on the perioperative outcomes of pelvi-acetabular fracture surgeries in the apex trauma centre of a developing country-a retrospective analysis.

Background: Regional anaesthesia has been proposed to reduce intraoperative blood loss, duration of hospital stay and in-hospital complications with improved postoperative pain control. General anaesthesia is advantageous for prolonged surgeries. We hypothesized that combined regional and general anaesthesia would offer advantages of both in pelvi-acetabular fracture surgeries.

Synthesis, conjugation and relaxation studies of gadolinium(III)-4-benzothiazol-2-yl-phenylamine as a potential brain specific MR contrast agent.

Magnetic resonance (MR) imaging is widely used in clinical research to map the structural and functional organization of the brain. We have designed and synthesized a Gd-based specific MR contrast agent that binds to regions in the brain. The presented compound {4-[(4-benzothiazol-2-yl-phenylcarbamoyl)-methyl]-7,10-bis-carboxymethyl-1,4,7,10-tetraazacyclododec-1-yl} acetic acid (DO3A-BT) was synthesized by conjugating the chloroacetylated product of 4-benzothiazol-2-yl-phenylamine with a trisubstituted cyclen.

Gold nanoparticles: an era in bionanotechnology.

Introduction: Gold nanoparticles have been efficiently and effectively used for the delivery of biomolecules and genes along with the potential to offer extremely sensitive diagnostics and imaging methods.

Areas Covered: This review discusses the historical aspects, synthesis of gold nanoparticles, gold nanoparticles as drug delivery vehicles, photothermal effect of gold nanoparticles and the applications of gold nanoparticles. Gold nanoparticles with their unique optical properties may be useful as biosensors in living cells and has application in the field of drug delivery and photothermal therapy.

Comparative evaluation of ketamine - propofol, fentanyl - propofol and butorphanol-propofol on haemodynamics and laryngeal mask airway insertion conditions.

Background: Laryngeal mask airway is a non invasive supraglottic device which has led to a radical change in the management of modern general anaesthesia. Propofol as a single agent is unsatisfactory and to overcome problems associated with LMA insertions. In the present study, we evaluated the haemodynamic changes and laryngeal mask airway insertion conditions comparing ketamine and opioids as adjuncts to propofol.

Design, synthesis, and fluorescence lifetime study of benzothiazole derivatives for imaging of amyloids.

The imaging of the distribution of β-amyloid plaques in the brain is becoming an important diagnostic modality in Alzheimer's disease. The present study reports the synthesis of novel benzothiazole derivatives. The final products were characterized by spectral techniques such as FTIR, (1)H NMR, and electrospray ionization-mass spectrometry.
