Agricultural activities in catchments can cause excessive nutrient loads in waterways. Catchment nitrogen (N) and phosphorus (P) flows may be intercepted and assimilated by riparian vegetation. While prior studies suggest that woody vegetation is preferable for reducing P loads, the question remains: is woody vegetation or grass cover more effective at reducing catchment N and P exports to waterways. To address this we investigated the relative importance of vegetation type, hydrologic and soil microbial processes on N and P losses from soil to a stream...

A series of dimeric isoxazolyl-1,4-dihydropyridines (IDHPs) were prepared by click chemistry and examined for their ability to bind the multi-drug resistance transporter (MDR-1), a member of the ATP-binding cassette superfamily (ABC). Eight compounds in the present study exhibited single digit micromolar binding to this efflux transporter. One monomeric IDHP m-Br-1c, possessed submicromolar binding of 510nM at MDR-1. Three of the dimeric IDHPs possessed <1.5µM activity, and 4b and 4c were observed to have superior binding selectivity compared to their corresponding monomers verses the voltage gated calcium channel (VGCC)...

Cancers are composed of cells with distinct molecular and phenotypic features within a given tumor, a phenomenon termed intratumor heterogeneity (ITH). Previously, we have demonstrated genomic ITH in localized lung adenocarcinomas; however, the nature of methylation ITH in lung cancers has not been well investigated. In this study, we generated methylation profiles of 48 spatially separated tumor regions from 11 localized lung adenocarcinomas and their matched normal lung tissues using Illumina Infinium Human Methylation 450K BeadChip array...

An important mandate when imaging pediatric patients is the reduction of radiation exposure to the lowest possible level consistent with good quality diagnostic imaging, so individual selection of radiopharmaceutical dosage and imaging technique is essential. Although the logistics of image acquisition and the approach to interpretation mirror the more common use in adults, the challenges of imaging young children typically require greater attention to patient preparation, positioning, and supervision during imaging, with the use of parental or family engagement in the procedure, gentle restraint, and occasionally the need for sedation...

Archery has experienced a recent resurgence in participation and has seen increases in archery range attendance and in children and young adults seeking archery lessons. Popular literature and movies prominently feature protagonists well versed in this form of weaponry. Periodic homicide cases in the United States involving bows are reported, and despite this and the current interest in the field, there are no manuscripts published on a large series of arrow wounds. This experiment utilizes a broad selection of modern arrowheads to create wounds for comparison...

Acute external injury to the larynx is both life threatening and a potential long term management challenge. As Otorhinolaryngologist we must be prepared and well versed to manage these patients. In our study seven patients of open laryngeal traumas were managed by primary closure. In five patients nature of injury was known in other two patients exact nature of injury was not known. After primary closure five patients with known injury survived and two patients with unknown injury died. As per our experience, we recommend primary closure, if the exact nature of injury is known as the outcome is definitely favourable...

Normal sleep related rapid eye movement sleep atonia, reduced lung volumes, reduced chemosensitivity, and impaired airway dilator activity, become significant vulnerabilities in the setting of neuromuscular disease. In that context, the compounding effects of respiratory muscle weakness and disease-specific features that promote upper airway collapse or cause dilated cardiomyopathy, contribute to various sleep-disordered breathing events. The reduction in lung volumes with neuromuscular disease is further compromised by sleep and the supine position, exaggerating the tendency for upper airway collapse and desaturation with sleep-disordered breathing events...

The nose is a complex, three-dimensional structure that is supported by a framework of osseous and cartilaginous structures. Disruption of this framework can result in nasal deformity and functional deficits. Nasal reconstruction requires restoration of the osseous and cartilaginous framework. This requires careful preoperative assessment of the nasal defect and understanding the nasal and facial aesthetics that are supported by the osseous and cartilaginous support structures. Structural grafts can be classified as restorative, supportive, or contouring...
