The systemic pathology of cerebral malaria in African children

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
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

A unified approach to dissecting biphasic responses in cell signaling

open access: yeseLife, 2023
Biphasic responses are encountered at all levels in biological systems. At the cellular level, biphasic dose-responses are widely encountered in cell signaling and post-translational modification systems and represent safeguards against overactivation or

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

“Gray Carbon” in Sewage Treatment Plants: A Neglected Carbon Sink

open access: yesOcean-Land-Atmosphere Research
This study introduces the concept of “gray carbon,” emphasizing its critical role in carbon sequestration in sewage treatment. By focusing on recalcitrant dissolved organic carbon (RDOC) in sewage effluents and its subsequent transformation in marine ...

Carbon sequestration [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2007
Developing technologies to reduce the rate of increase of atmospheric concentration of carbon dioxide (CO2) from annual emissions of 8.6 Pg C yr–1from energy, process industry, land-use conversion and soil cultivation is an important issue of the twenty-first century.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Biochar conductivity enhances methane generation in paddy soil by facilitating electron transfer mediated by dissolved organic matter

open access: yesBiochar
Biochar can regulate methane (CH4) emissions from paddy soils. However, the mechanism through which biochar conductivity influences methanogenesis in paddy soils remains unclear.

Estimating the costs of atmospheric carbon reductions in Mexico [PDF]

open access: yes, 2003
Trading in carbon emissions is a means of ensuring that supplies with the lowest marginal costs of emissions reduction are commissioned first. To analyse the potential for Mexican suppliers to participate in an emissions trading market, the relative cost-
