Investigations on 2-(4-Cyanophenylamino) acetic acid by FT-IR,FT-Raman, NMR and UV-Vis spectroscopy, DFT (NBO, HOMO-LUMO, MEP and Fukui function) and molecular docking studies.

Extensive quantum chemical calculation have been carried out to investigate the Fourier Transform Infrared(FT-IR), Fourier Transform Raman(FT-RAMAN) and Nuclear magnetic resonance(NMR), and Ultra Violet-Visible(UV-vis) spectra of 2-(4-Cyanophenylamino) acetic acid. The molecular structure, fundamental vibrational frequencies and intensities of the vibrational bands were interpreted with the aid of optimizations and normal coordinate force field calculations based on density functional theory (DFT) and ab initio HF methods with 6-311++G(d,p) basis set. The theoretical vibrational wavenumbers are compared with the experimental values.

Outcome of early coronary intervention for acute ST elevation myocardial infarction in a tertiary care cardiac centre in Sri Lanka.

Objectives: To describe the outcomes of early percutaneous coronary intervention (PCI) for the treatment of acute ST elevation myocardial infarction (STEMI) in a tertiary care cardiac centre in Colombo, Sri Lanka.

Methods: Medical records of 139 consecutive patients presenting to Cardiology Unit 5, National Hospital of Sri Lanka from March 2013 to June 2014 with acute STEMI, and treated with early PCI as a mode of reperfusion were reviewed. These patients were then followed up for 6 months to determine survival, target-vessel revascularization, in-stent thrombosis and other major adverse cardiac events (MACE).

Experience of peptic ulcer perforation over a decade in a teaching hospital of southern Bangladesh.

Objective: To determine disease characteristics, check the treatment status and compare outcome with other series.

Design And Setting: A retrospective study in a single unit of the Department of Surgery of Khulna Medical College Hospital, south west Bangladesh.

Patients And Methods: After diagnosis by clinical and radiological examination, 491 patients were treated during the period July 1992 to November 2002.

Synergism of ultrasound and solid acids in intensification of Friedel-Crafts acylation of 2-methoxynaphthalene with acetic anhydride.

The Friedel-Crafts acylation of 2-methoxynaphthol is generally carried out by using highly polluting acids such as HF, AlCl(3), BF(3) which are used in more than stoichiometric quantities and are neutralized at the end creating large quantities of waste, corrosion problems and hazard. This paper discusses the use of acid treated clays such as K-10 and Filtrol-24 and cation exchange resins such as Amberlyst-36, Amberlyst-15 and Indion-130 as catalysts at 25 degrees C which have different acid strengths and pore size distributions. The activities were in the following order:Amberlyst-36>Indion-130>Amberlyst-15>K-10clay>Filtrol-24.
