Aspiring While Waiting: Temporality and Pacing of Ghanaian Stayer Youth's Migration Aspirations

Many youth in Global South countries, whose parents have migrated abroad while they have stayed, i.e., "stayer youth," also aspire to migrate. While the current literature depicts stayer youth as "waiting" to emigrate, connoting passivity, recent critical youth studies suggest the importance of centring young people's agency when focusing on their aspirations and experiences. This article investigates how stayer youth in Ghana "pace" their migration aspirations while "waiting." By observing how youth change their aspirations over time, we first distinguish between different aspirations according to when youth first aim to migrate. Second, we "follow" stayer youth after their secondary school graduation to understand how they seek to fulfil their migration aspirations and the strategies they adopt therein. We use ethnographic data from 38 Ghanaian "stayer" young people. Our analyses show that stayer youth adapt their decision‐making when they realise some misalignment between their migration aspirations and capabilities. By analysing their adaptation strategies, we emphasise stayer youth's agency despite structural forces confining them to what has been called "waithood.

Hydrophobic lung surfactant proteins B and C remain associated with surface film during dynamic cyclic area changes

AbstractThe biophysical activity of lung surfactant depends, to a large extent, on the presence of the hydrophobic surfactant proteins B (SP-B) and C (SP-C). The role of these proteins in lipid adsorption and lipid squeeze-out under dynamic conditions simulating breathing is not yet clear. Therefore, the aim of this study was to investigate the interaction of spread hydrophobic surfactant proteins with phospholipids in a captive-bubble surfactometer during rapid cyclic area changes (6 cycles/min). We found that SP-B and SP-C facilitated the rapid transport of lipids into the air–water interface in a concentration-dependent manner (threshold concentration ≥0.05:0.5 mol% SP-B/SP-C). Successive rapid cyclic area changes did not affect the concentration-dependent lipid adsorption process, suggesting that SP-B and SP-C remained associated with the surface film

Antimicrobial host defence peptides: functions and clinical potential

Cationic host defence peptides (CHDP), also known as antimicrobial peptides, are naturally occurring peptides that can combat infections through their direct microbicidal properties and/or by influencing the host's immune responses. The unique ability of CHDP to control infections as well as resolve harmful inflammation has generated interest in harnessing the properties of these peptides to develop new therapies for infectious diseases, chronic inflammatory disorders and wound healing. Various strategies have been used to design synthetic optimized peptides, with negligible toxicity. Here, we focus on the progress made in understanding the scope of functions of CHDP and the emerging potential clinical applications of CHDP-based therapies

Developmental regulation of chicken surfactant protein A and its localization in lung

AbstractSurfactant Protein A (SP-A) is a collagenous C-type lectin (collectin) that plays an important role in the early stage of the host immune response. In chicken, SP-A (cSP-A) is expressed as a 26 kDa glycosylated protein in the lung. Using immunohistochemistry, cSP-A protein was detected mainly in the lung lining fluid covering the parabronchial epithelia. Specific cSP-A producing epithelial cells, resembling mammalian type II cells, were identified in the parabronchi. Gene expression of cSP-A markedly increased from embryonic day 14 onwards until the time of hatch, comparable to the SP-A homologue chicken lung lectin, while mannan binding lectin and collectins CL-L1 and CL-K1 only showed slightly changed expression during development. cSP-A protein could be detected as early as ED 18 in lung tissue using Western blotting, and expression increased steadily until day 28 post-hatch. Our observations are a first step towards understanding the role of this protein in vivo
