The evil circle of poverty: a qualitative study of malaria and disability
<p>Abstract</p> <p>Background</p> <p>This article discusses the link between disability and malaria in a poor rural setting. Global malaria programmes and rehabilitation programmes are organized as vertical and separate programmes, and as such they focus on prevention, cure and control, and disability respectively. When looking at specific conditions and illnesses, the impairing long-term consequences of illness incidents during childhood are not questioned.</p> <p>Methods</p> <p>The study design was ethnographic with an open, exploratory approach. Data were collected in Mangochi District in Malawi through qualitative in-depth interviews and participant observation.</p> <p>Results</p> <p>Despite a local-based health service system, people living in poor rural areas are confronted with a multitude of barriers when accessing malaria prevention and treatment. Lack of skilled health personnel and equipment add to the general burden of poverty: insufficient knowledge about health care, problems connected to accessing the health facility in time, insufficient initiatives to prevent malaria attacks, and a general lack of attention to the long term disabling effects of a malaria attack.</p> <p>Conclusions</p> <p>This study points to the importance of building malaria programmes, research and statistics that take into consideration the consequences of permanent impairment after a malaria attack, as well as the context of poverty in which they often occur. In order to do so, one needs to develop methods for detecting people whose disabilities are a direct result of not having received health services after a malaria episode. This may be done through qualitative approaches in local communities and should also be supplemented by suitable surveys in order to estimate the problem on a larger scale.</p
Optimality of broken extremals
In this paper we analyse the optimality of broken Pontryagin extremal for an
n-dimensional affine control system with a control parameter, taking values in
a k- dimensional closed ball. We prove the optimality of broken normal
extremals when n = 3 and the controllable vector fields form a contact
distribution, and when the Lie algebra of the controllable fields is locally
orthogonal to the singular locus and the drift does not belong to it. Moreover,
if k = 2, we show the optimality of any broken extremal even abnormal when the
controllable fields do not form a contact distribution in the point of
singularity.Comment: arXiv admin note: text overlap with arXiv:1610.0675
Genetic regulation of glucoraphanin accumulation in BenefortĆ©Ā® broccoli
Diets rich in broccoli (Brassica oleracea var italica) have been associated with maintenance of cardiovascular health and reduction in risk of cancer. These health beneļ¬ts have been
attributed to glucoraphanin that speciļ¬cally accumulates in broccoli. The development of broccoli with enhanced concentrations of glucoraphanin may deliver greater health beneļ¬ts.
Three high-glucoraphanin F1 broccoli hybrids were developed in independent programmes through genome introgression from the wild species Brassica villosa. Glucoraphanin and other metabolites were quantiļ¬ed in experimental ļ¬eld trials. Global SNP analyses quantiļ¬ed the differential extent of B. villosa introgression
The high-glucoraphanin broccoli hybrids contained 2.5ā3 times the glucoraphanin content of standard hybrids due to enhanced sulphate assimilation and modiļ¬cations in sulphur partitioning between sulphur-containing metabolites. All of the high-glucoraphanin hybrids possessed an introgressed B. villosa segment which contained a B. villosa Myb28 allele. Myb28
expression was increased in all of the high-glucoraphanin hybrids. Two high-glucoraphanin hybrids have been commercialised as Beneforte broccoli.
The study illustrates the translation of research on glucosinolate genetics from Arabidopsis to broccoli, the use of wild Brassica species to develop cultivars with potential consumer beneļ¬ts, and the development of cultivars with contrasting concentrations of glucoraphanin for use in blinded human intervention studie
