REVIEW
Thankamma Ajithkumar, Stephen Price, Gail Horan, Amos Burke, Sarah Jefferies
Neurocognitive dysfunction is the leading cause of reduced quality of life in long-term survivors of paediatric brain tumours. Radiotherapy is one of the main contributors to neurocognitive sequelae. Current approaches for prevention and reduction of neurocognitive dysfunction include avoidance of radiotherapy in young children and reduction of the radiotherapy dose and volume of brain irradiated. Substantial advances have been made in brain imaging, especially with functional imaging and fibre tracking with the use of diffusion tensor imaging...

Open physeal fractures of the distal phalanx of the hallux are the lesser described counterpart to the same fracture of the finger, known by its eponym as a "Seymour fracture". Displaced Salter-Harris phalangeal fractures present with a concomitant nailbed or soft tissue injury. Often these fractures occur in the summer months when open-toe footwear can be worn, however, they may occur indoors as well. Frequently, the injury results from direct axial load of the toe, or "stubbing", which causes the fracture and associated soft tissue injury...

The frequency of sexual victimization in high-risk populations like adolescents in institutional care has hardly been studied. In this study, we report lifetime prevalence and incidence from a nationwide German sample including 322 adolescents (mean age 16.69 years, 43% female) from 20 residential care facilities and 12 boarding schools. Lifetime prevalence for severe sexual victimization (in and outside of institution) was 46.7% for girls and 8.0% for boys. Moreover, 5% of all adolescents experienced severe sexual victimization for the first time after they were admitted to the current institution (mean duration of stay in the current institution 3...

Several locations in the Elizabeth River, VA, USA are highly contaminated with polycyclic aromatic hydrocarbons (PAHs) due to the release of creosote mixtures from wood treatment facilities. Interestingly, some populations of Atlantic killifish (Fundulus heteroclitus) inhabiting the Elizabeth River (ER) are resistant to PAH-induced teratogenesis. However, evolutionary resistance to PAHs due to chronic PAH exposure is associated with reduced fitness and increased susceptibility to other environmental stressors in at least one PAH-resistant ER killifish population...

Herein, we presented a facile strategy for highly sensitive and selective detection of both Cu(2+) and histidine (His) by combining the peroxidase-like nanozyme activity of gold nanoclusters with amino acid's ambidentate nature. The peroxidase-like catalytic ability of histidine-Au nanoclusters (His-AuNCs) can be inhibited by the addition of Cu(2+). The sensitivity of this probe to Cu(2+) is significant with a linear range of 1-100nM, and a low detection limit of 0.1nM. More interestingly, His-AuNC/Cu(2+) undergoes recovery of the activity upon exposure to free His, because His/Cu(2+) complex is more stable due to the participation of the imidazole ring of His...

Since controlling hydrogen ion concentration (i.e. pH) is fairly important in various fields, developing a facile pH detection method is highly desired. Owing to the superior optical properties, semiconductor quantum dots (QDs) have been developed as a promising alternative for organic fluorophores in fluorescence analysis. In this study, a hydrophilic p-aminothiophenol (pATP) capped CdSe/ZnS QDs (denoted as pATP-QDs) as a selective "turn-on" fluorescence probe for pH in aqueous media is reported. The pATP-QDs probe easily obtained via ligand exchange are characterized by various analytic techniques including ultraviolet-visible, fourier transform infrared, fluorescence, time-resolved fluorescence spectroscopies, and transmission electron microscope etc...

Bowl-like monodispersed porous carbon nanoparticles (BMPCNs) have been successfully prepared with a facile and scalable approach, and the as-prepared BMPCNs are examined thoroughly by various physical characterizations. Physical measurements display that BMPCNs have the high surface area (1255m(2)g(-1)), hierarchical porosity, a certain amount of oxygen-containing groups and high graphitization degree. These unique structure features endow BMPCNs with a high capacitance (281Fg(-1) at 0.5Ag(-1)), excellent rate capability (209Fg(-1) at 50Ag(-1)), and outstanding cycling stability (94...

BACKGROUND: Despite emerging drug resistance in Cambodia, artemisinin-based combination therapy (ACT) is still the most efficacious therapy. ACT is available free of charge in the Cambodian public sector and at a subsidized rate in the private sector. However, un- and mistreated cases in combination with population movements may lead to the further spread of resistant parasites, stressing the importance of understanding how the perceived aetiology of malaria and associated health-seeking behaviour may delay access to appropriate treatment...
