Concurrent ascending colon adenocarcinoma and colonic tuberculosis: a case report from Syria.

Introduction And Importance: Tuberculosis (TB) has been one of the most devastating diseases to humanity in recent decades; although pulmonary infection is the most common, infection of any other organ is familiar as well. Colon cancer is another disease affecting the gastrointestinal (GI) system and mostly targets people over 50. Only a few studies mentioned the co-existence of cancer and TB occurring at the same place and time.

Ion Pair Supramolecular Structure Identified by ATR-FTIR Spectroscopy and Simulations in Explicit Solvent*.

The present work uses ATR-FTIR spectroscopy assisted by simulations in explicit solvent and frequency calculations to investigate the supramolecular structure of carboxylate alkali-metal ion pairs in aqueous solutions. ATR-FTIR spectra in the 0.25-4.

Conformational analysis by UV spectroscopy: the decisive contribution of environment-induced electronic Stark effects.

UV chromophores are frequently used as probes of the molecular structure. In particular, they are sensitive to the electric field generated by the molecular environment, resulting in the observation of Stark effects on UV spectra. While these environment-induced electronic Stark effects (EI-ESE) are already used for conformational analysis in the condensed phase, this work explores the potential of such an approach when performed at much higher conformational resolution in the gas phase.

Adeno-associated virus capsid assembly is divergent and stochastic.

Adeno-associated viruses (AAVs) are increasingly used as gene therapy vectors. AAVs package their genome in a non-enveloped T = 1 icosahedral capsid of ~3.8 megaDalton, consisting of 60 subunits of 3 distinct viral proteins (VPs), which vary only in their N-terminus.

Electronic Stark Effect in Isolated Ion Pairs.

Stark spectral shifts of a molecular probe are commonly used to estimate the local electric field in condensed media. The very large fields reported, typically in the 0.1-10 GV m range, are, however, difficult to reproduce in a controlled manner, limiting the calibration of these molecular probes to ranges below 0.
