Pneumatoceles due to acquired localized overinflation as a form of pulmonery interstitial emphysema are complications of advanced bronchopulmonary dysplasia. Different ventilation modes, selective bronchial intubation, ballon obstruction of the affected bronchus and steroids have been reported with success. Lobectomy has also been used. We present a premature infant with multiple large pneumatoceles causing respiratory compromise. In our case percuteneous decompression under fluoroscopy guidance ...

Abstract The effects of planar defects and composition on Ar mobility in trioctahedral micas have been investigated in samples from a small marble outcrop (∼500 m2) in the Frontenac Terrane, Grenville Province, Ontario. These micas crystallized during amphibolite-facies metamorphism at ∼1170 Ma and experienced a thermal pulse ∼100 Ma later at shallow crustal levels associated with the emplacement of plutons. 87Rb/86Sr ages of the phlogopites range from ∼950 to ∼1050 Ma, consistent with resetting during ...

The continental shelf ecosystem on the Eastern Scotian Shelf (ESS) has experienced drastic changes. Once common top predators are a small fraction of their historical abundance, and much of the current community structure is now dominated by pelagic fishes and invertebrates. Embedded within this food web, Atlantic cod and gray seal populations have recently exhibited nearly opposite trends. Since 1984, cod populations have decreased exponentially at a rate averaging 17% per year, whereas gray seals ...

The use of shear-wave splitting analysis as a tool for fracture analysis is well established. In this article, we discuss the analysis of shear-wave splitting in a relatively new context—shallow heavy oil plays where we believe stress is the dominant cause of the shear-wave splitting, rather than macroscale fracturing. There is clear laboratory evidence in the literature for shear-wave splitting caused by differential stress, which we believe supports this viewpoint. We are particularly interested ...

Processing of low-level visual information shows robust developmental gains through childhood and adolescence. However, it is unknown whether low-level visual processing in the occipital cortex supports age-related gains in memory for complex visual stimuli. Here, we examined occipital alpha activity during visual scene encoding in 24 children and adolescents, aged 6.2-20.5 years, who performed a subsequent memory task while undergoing electrocorticographic recording. Scenes were classified as high- ...

The modulation of the reactivity of metal oxo species by redox inactive metals has attracted much interest due to the observation of redox inactive metal effects on processes involving electron transfer both in nature (the oxygen-evolving complex of Photosystem II) and in heterogeneous catalysis (mixed-metal oxides). Studies of small-molecule models of these systems have revealed numerous instances of effects of redox inactive metals on electron- and group-transfer reactivity. However, the heterometallic ...

The most ubiquitous gap junction protein within the body, connexin 43 (Cx43), is a target of interest for modulating the dermal wound healing response. Observational studies found associations between Cx43 at the wound edge and poor healing response, and subsequent studies utilizing local knockdown of Cx43 found improvements in wound closure rate and final scar appearance. Further preclinical work conducted using Cx43-based peptide therapeutics, including alpha connexin carboxyl terminus 1 (αCT1), ...

Patients with autoimmune and inflammatory conditions often receive long-term immunosuppressive therapy. Some of the largest patient populations with iatrogenic immunosuppression include patients who have received solid-organ transplants or who have rheumatoid arthritis or psoriasis. Although treatments improve patient outcomes, individuals with immunosuppression subsequently may have an increased risk of skin cancer, including squamous cell carcinoma, basal cell carcinoma, and malignant melanoma.

Maternal malaria is a tropical scourge associated with poor pregnancy outcomes. Women become resistant to Plasmodium falciparum pregnancy malaria as they acquire antibodies to the variant surface antigen VAR2CSA, a leading vaccine candidate. Because malaria infection may increase VAR2CSA antibody levels and thereby confound analyses of immune protection, gravidity-dependent changes in antibody levels during and after infection, and the effect of VAR2CSA antibodies on pregnancy outcomes were evaluated. ...

Syntheses of rare examples of U(V) methyl and U(IV) ylide complexes are reported. Reaction of the previously reported U(IV) imido complex [(C5Me5)2U(py)(═NMes)] (py = pyridine, and Mes = 2,4,6-Me3C6H2) with CuI forms the U(V) complex [(C5Me5)2U(I)(═NMes)]. Reaction of the iodo complex with MgMe2 produces the methyl complex [(C5Me5)2U(CH3)(═NMes)]. The methyl complex was reacted with CH2PPh3, surprisingly forming [(C5Me5)2U(CH2PPh3)(═NMes)], a U(IV) ylide. This is formed from a disproportionation of a transient ...
