Plasmodium has a complex life cycle that spans between mosquito and human. For survival and pathogenesis it banks upon dynamic alterations in ionic transport across organelle and plasma membrane. Being a fundamental contributor of crucial biological processes in parasite, ionic balance facilitates parasite invasion, augmentation and transmission. Past few decades have witnessed tremendous advancement in understanding the relevance of ionic transit in parasites. Perhaps, not surprisingly, disruption of ionic homeostasis was thought to be detrimental for parasite...

Consistent between-individual differences in movement are widely recognised across taxa. In addition, foraging plasticity at the within-individual level suggests a behavioural dependency on the internal energy demand. Because behaviour co-varies with fast-slow life history (LH) strategies in an adaptive context, as theoretically predicted by the pace-of-life syndrome hypothesis, mass/energy fluxes should link behaviour and its plasticity with physiology at both between- and within-individual levels. However, a mechanistic framework driving these links in a fluctuating ecological context is lacking...

Cyclones are significant drivers of change within mangrove ecosystems with the extent of initial damage determined by storm severity, location and distribution (exposure), and influenced by species composition and structure (e.g., height). The long-term recovery of mangroves is often dependent upon hydrological regimes, as well as the frequency of storm events. On February 3, 2011, Tropical Cyclone Yasi (Category 5) made landfall on the coast of north Queensland Australia with its path crossing the extensive mangroves within and surrounding Hinchinbrook Island National Park...

Aluminum-based adjuvant (e.g., aluminum oxyhydroxide (AlO(OH), known as the commercial Alhydrogel® (Alum)) is the first adjuvant to be used in human vaccines. Although Alum shows a robust induction of antibody-mediated immunity, its weak stimulation of cell-mediated immunity makes it a questionable adjuvant for cancer immunotherapy. Herein, we described a novel formulation of Alum-based adjuvant by preparing AlO(OH)-modified graphene oxide (GO) nanosheets (GO-AlO(OH)), which, in addition to maintaining the induction of humoral immune response by AlO(OH), could further elicit the cellular immune response by GO...
