Synthesis, Characterisation, and Preliminary In Vitro Studies of Vanadium(IV) Complexes with a Schiff Base and Thiosemicarbazones as Mixed Ligands

[VO(sal‐L‐tryp)(H2O)] (1, sal‐L‐tryp = N‐salicylidene‐L‐tryptophanate) was used as a precursor to produce the new complexes [VO(sal‐L‐tryp)(MeATSC)]·1.5C2H5OH [2, MeATSC = 9‐Anthraldehyde‐N(4)‐methylthiosemicarbazone], [VO(sal‐L‐tryp)(N‐ethhymethohcarbthio)]·H2O [3, N‐ethhymethohcarbthio = (E)‐N‐ethyl‐2‐(4‐hydroxy‐3‐methoxybenzylidene)hydrazinecarbothioamide] and [VO(sal‐L‐tryp)(acetylethTSC)]·C2H5OH {4, acetylethTSC = (E)‐N‐ethyl‐2‐[1‐(thiazol‐2‐yl)ethylidene]hydrazinecarbothioamide} by reaction with the respective thiosemicarbazone. The chemical and structural properties of these ligands and complexes were characterised by elemental analysis, ESI‐MS, FTIR, UV/Vis, ESR and 1H and 13C NMR spectroscopy and X‐ray crystallography. Dimethyl sulfoxide (DMSO) and [D6]DMSO solutions of 1–4 were oxidised in air to produce vanadium(V) species, which were verified by ESI‐MS and 51V NMR spectroscopy. The anticancer properties of 2–4 were examined with three colon cancer cell lines, HTC‐116, Caco‐2 and HT‐29, and noncancerous colonic myofibroblasts, CCD18‐Co. Compounds 2–3 exhibited less inhibitory effects in the CCD‐18Co cells, which indicates a possible cytotoxic selectivity towards colon cancer cells. In general, compounds that exhibit antiproliferative activity to cancer cells but do not affect noncancerous cells may have a potential in chemotherapy

Why do women invest in pre-pregnancy health and care? A qualitative investigation with women attending maternity services

Background Despite the importance attributed to good pre-pregnancy care and its potential to improve pregnancy and child health outcomes, relatively little is known about why women invest in pre-pregnancy health and care. We sought to gain insight into why women invested in pre-pregnancy health and care. Methods We carried out 20 qualitative in-depth interviews with pregnant or recently pregnant women who were drawn from a survey of antenatal clinic attendees in London, UK. Interviewees were purposively sampled to include high and low investors in pre-pregnancy health and care, with variation in age, partnership status, ethnicity and pre-existing medical conditions. Data analysis was conducted using the Framework method. Results We identified three groups in relation to pre-pregnancy health and care: 1) The “prepared” group, who had high levels of pregnancy planning and mostly positive attitudes to micronutrient supplementation outside of pregnancy, carried out pre-pregnancy activities such as taking folic acid and making changes to diet and lifestyle. 2) The “poor knowledge” group, who also had high levels of pregnancy planning, did not carry out pre-pregnancy activities and described themselves as having poor knowledge. Elsewhere in their interviews they expressed a strong dislike of micronutrient supplementation. 3) The “absent pre-pregnancy period” group, had the lowest levels of pregnancy planning and also expressed anti-supplement views. Even discussing the pre-pregnancy period with this group was difficult as responses to questions quickly shifted to focus on pregnancy itself. Knowledge of folic acid was poor in all groups. Conclusion Different pre-pregnancy care approaches are likely to be needed for each of the groups. Among the “prepared” group, who were proactive and receptive to health messages, greater availability of information and better response from health professionals could improve the range of pre-pregnancy activities carried out. Among the “poor knowledge” group, better response from health professionals might yield greater uptake of pre-pregnancy information. A different, general health strategy might be more appropriate for the “absent pre-pregnancy period” group. The fact that general attitudes to micronutrient supplementation were closely related to whether or not women invested in pre-pregnancy health and care was an unanticipated finding and warrants further investigation.This report is independent research commissioned and funded by the Department of Health Policy Research Programme Pre-Pregnancy Health and Care in England: Exploring Implementation and Public Health Impact, 006/0068

Two cultures, one identity: formulations of Australian Isma'ili Muslim identity

The Shi'a Imami Nizari Isma'ili Muslims have often been considered the "poster child" for pluralistic integration (Cayo 2008). This ethos has been inculcated within members of the community, with its adherents seeing themselves as a diverse and multi-ethnic collective. Nevertheless, despite this purported pluralism, social research on the Isma'ilis has primarily focused on the diasporic and post-diasporic migrant communities of South Asian descent, the 'first and second-generation immigrants,' in the Euro-American context (Mukadam and Mawani 2006, 2009; Nanji 1983, 1986). The experiences of co-religionists in other contexts have often been neglected. This study examines how members of the self-described geographically and socially isolated Isma'ili community in Australia construct their identity vis-à-vis the larger, global, Isma'ili community, and how they have responded to the potential of identity threat given the arrival of another group of Isma’ilis with a differing migratory history integrating into the extant community. Using the approach of identity process theory, this study examines how salient features of identity are constructed amongst the Australian Isma'ilis, how religion and identity take on multiple meanings within the Australian Isma'ili context, and, finally, sheds light on the self-sufficiency of this community despite geographic and social isolation

Fair Trade/Organic Coffee, Rural Livelihoods, and the "Agrarian Question": Southern Mexican Coffee Families in Transition

Summary We use a random sample of coffee producing households in southern Mexico to compare opportunities associated with government subsidies and migration to the role of Fair Trade/organic coffee in household livelihoods. Although land and labor returns among Fair Trade/organic coffee growers are higher than for conventional growers, differences in yields are more important than price premiums. Moreover, investment in education and labor opportunities outside coffee dominate those in Fair Trade/organic coffee. The results highlight the value of an integrated approach to the agrarian question that improves productivity and prices and supports other pathways for improving incomes.Latin America Mexico Fair Trade organic migration education

Fair Trade-Organic Coffee Cooperatives, Migration, and Secondary Schooling in Southern Mexico

From 1995 to 2005 educational attainment of youth in rural Southern Mexico rose dramatically. Three distinct trends emerged in the region that could explain the rise in education. First, thousands of coffee-producing households joined cooperatives that have entered Fair Trade relationships and/or began adopting organic practices. Then, beginning in approximately 2000, US migration took off, while intra-Mexico migration steadily increased, providing remittance income and more lucrative alternatives in labor markets outside of coffee production. Third, Progresa/Oportunidades, a conditional cash transfer program aimed at promoting education, became available to families in the region in 1998 and 1999. Using survey data from 845 coffee farming households in Oaxaca and Chiapas, Mexico, this paper explores how participation in Fair Trade-organic cooperatives coffee price premiums, migration, and Progresa/Oportunidades shape education attainment for young adults (16-25). Results from a household fixed-effects model show that participating in a Fair Trade-organic cooperative contributed to a one-half year increase in schooling for girls over the study period. The impacts of US migration opportunities appear to have even stronger positive impacts on years of schooling for females, while for males increased migration opportunities tend to diminish the positive effects of being in a Fair Trade- organic cooperative on educational attainment.Latin America, Mexico, Fair Trade, Organic, Migration, Education.

Thermotropic Liquid-crystalline Properties of Extended Viologen Bis(triflimide) Salts

A series of extended, symmetric viologen triflimides were synthesised by the metathesis reaction of lithium triflimide with the respective viologen tosyalates in methanol. Their chemical structures were characterised by Fourier Transform Infrared, 1H and 13C Nuclear Magnetic Resonance spectroscopy and elemental analysis. Their thermotropic liquid-crystalline (LC) properties were examined by a number of experimental techniques including differential scanning calorimetry, thermogravimetric analysis, polarising optical microscopy and variable temperature X-ray diffraction. The viologen salts containing alkyl chain of two carbon and three carbon atoms were relatively low melting salts. Those of alkyl chains of four carbon and five carbon atoms formed ionic liquids at 88 and 42°C, respectively. Those of alkyl chain of 9, 10 and 11 carbon atoms were high melting salts, as high as 166°C. Those of higher alkyl chains of 16, 18 and 20 carbon atoms showed thermotropic LC phases forming SmC, SmA and an unidentified smectic (SmX) phases, and showed SmA to isotropic transitions at high temperatures. As expected, all the viologen triflimides had excellent stabilities in the temperature range of 338–365°C
