The sequestration of carbon and nitrogen by clay-sized particles in soils is well established, and clay content or mineral surface area has been used to estimate the sequestration potential of soils. Here, via incubation of a sieved (<2 mm) topsoil with labelled litter, we find that only some of the clay-sized surfaces bind organic matter (OM). Surprisingly, <19% of the visible mineral areas sh...
Pediatric cerebral malaria carries a high mortality rate in sub-Saharan Africa. We present our systematic analysis of the descriptive and quantitative histopathology of all organs sampled from a series of 103 autopsies performed between 1996 and 2010 in Blantyre, Malawi on pediatric cerebral malaria patients and control patients (without coma, or without malaria infection) who were clinically w...
Greenhouse gas emissions have several adverse environmental effects, like pollution and climate change. Currently applied carbon capture and storage (CCS) methods are not cost effective and have not been proven safe for long term sequestration. Another attractive approach is CO2 valorization, whereby CO2 can be captured in the form of biomass via photosynthesis and is subsequently converted int...
This study develops an integrated assessment approach for analysis of the economic potential for carbon sequestration in agricultural soils. By linking a site-specific economic simulation model of agricultural production to a crop ecosystem model, the approach shows the economic efficiency of soil carbon (C) sequestration depends on site-specific opportunity costs of changing production practic...
Pulmonary sequestration is an uncommon condition that accounts for 0.5-6% of all pulmonary malformations and is typically diagnosed in childhood. Of the two forms of pulmonary sequestration, intralobar and extralobar, the latter is less frequently encountered. The current report describes the case of a 32-year-old female patient with chest and abdominal pain. Imaging (chest X-rays and CT scans ...
Bronchopulmonary sequestration is a relatively rare medical condition wherein a mass of nonfunctioning primitive lung tissue does not communicate with the tracheobronchial tree and receives its blood supply from an anomalous systemic artery.1-6 It usually manifests at younger ages and is rare in adults. Its clinical presentation varies in adulthood.1-3 We report the case of a young male adult w...
Pulmonary sequestration is an uncommon disease, accounting for only approximately 1.5% of all congenital pulmonary malformations. In most cases, the diagnosis is a result of accidental radiological findings; it is rarely accompanied by clinical symptoms, and is more commonly associated with other congenital malformations. Herein, we reported a case of pulmonary sequestration presented as massiv...
A case is described of a baby boy aged 7 months who was found to have total sequestration of the right lung, the right main bronchus communicating with the lower end of the oesophagus. This was discovered during investigation for supposed asthma, as the child had wheezed since birth. No episodes of cyanosis or difficulties with feeding had occurred. The embryological considerations are discusse...
A localised fibrous mesothelioma arising from an intralobar lung sequestration occurred in a 64 year old Turkish woman. This appears to be the first report of a mesothelioma occurring within a pulmonary sequestration.

Assuming that there is no GZK (Greisen-Zatsepin-Kuzmin) cut-off and that super-GZK cosmic rays correlate with AGN (Active Galactic Nuclei) at cosmological distances, it is speculated that a relic superheavy particle (X) has its lifetime enhanced by sequestration in an extra dimension. This sequestration is assumed to be partially liberated by proximity of merging supermassive black holes in an ...
