Introduction: Breast cancer is the most common malignancy amongst women and has a higher incidence rate than lung cancer. Its tumor progression partially results from inactivation of p53 which is caused by overexpression of ubiquitous regulatory proteins possessing p53-binding domain. RBBP6 is regarded as one of the ubiquitous proteins because of its RING finger-like domain which enables it to possess E3 ligase activity.

The aim of this paper was to establish whether the differences in the risks of union dissolution between cohabitors and non-cohabitors in Uganda have converged over time using event history data. Data were collected in 2013 from 1200 women in central Uganda using retrospective methods. Of these, 839 provided information on three types of first union: women who married directly (without first cohabiting), those who married following cohabitation and those who were still cohabiting.

Probing Molecular Interactions between Ammonium-Based Ionic Liquids and N,N-Dimethylacetamide: A Combined FTIR, DLS, and DFT Study.

J Phys Chem B

December 2016

Department of Chemistry, School of Mathematical and Physical Sciences, Materials Science Innovation & Modelling (MaSIM) Research Focus Area, Faculty of Agriculture, Science and Technology, North-West University (Mafikeng Campus), Private Bag X2046, Mmabatho 2735, South Africa.

The present study investigates the effects of the alkyl chain length of the cationic head-group of some ammonium-based ionic liquids (ILs) (having the same anion) on the interaction between the ILs and N,N-dimethylacetamide (DMA). The molecular interactions between the studied ILs, tetraethylammonium hydroxide (TEAH), tetrapropylammonium hydroxide (TPAH), tetrabutylammonium hydroxide (TBAH), and their binary mixtures with DMA were studied using the Fourier transform infrared spectroscopy (FTIR) technique, dynamic light scattering (DLS) experiments, and quantum chemical calculations. It was observed from both experimental FTIR analysis and theoretical studies that the strength of intermolecular interactions, such as hydrogen bonding, ion-ion interactions, and induced dipole interactions, between the ILs and DMA depends on the alkyl chain length of the IL cation head-group.

This study used data from the 2008 Ghana Demographic and Health Survey to investigate the association between selected socio-demographic factors and dietary behaviour as measured by fruit and vegetable consumption among a sample of 6139 young people aged 15-34 years in Ghana. Overall, fruit and vegetable consumption was low in young people, but females were likely to consume more fruit and vegetables than their male counterparts. Respondents from the Mande ethnic group, those who resided in rural areas and those living in the Brong/Ahafo, Ashanti and the Eastern regions consumed more fruit and vegetables than those from other regions.
