Infection and co-infection with helminths and Plasmodium among school children in Côte d'Ivoire : results from a National Cross-Sectional Survey [PDF]

open access: yes, 2014
Helminth infection and malaria remain major causes of ill-health in the tropics and subtropics. There are several shared risk factors (e.g., poverty), and hence, helminth infection and malaria overlap geographically and temporally.

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

open access: yesAdvanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

open access: yesAngewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Life-history responses, transmission dynamics and epidemiology in a terrestrial gastropod infected with parasitic mites [PDF]

open access: yes, 2010
Parasites are known to influence the life-history of their hosts. A parasite-induced reduction in host fecundity and survival may lead to a reduced rate of increase in the host population.

Adaptation of Echinococcus Multilocularis to Oxidative Stress Depends on EmPDK‐Mediated Metabolic Reprogramming

open access: yesAdvanced Science, EarlyView.
Metabolic adaption presents a vital survival strategy for E. multilocularis. This study identifies EmPDK as a central metabolic regulator governing glucose metabolic reprogramming. Oxidative stress activates EmHIF1α to induce EmPDK expression. Mechanistic characterization reveals this ROS/EmHIF1α/EmPDK axis drives glycolytic reprogramming to sustain ...

Artificial Intelligence‐Guided Phenotypic Drug Repurposing Against Streptococcus pneumoniae

open access: yesAdvanced Science, EarlyView.
Integrated artificial intelligence (AI) ensembles identify highly potent repurposed drugs against Streptococcus pneumoniae. Prospective virtual screening of 6747 drugs uncovers nine active candidates, including thiostrepton. This drug exhibits low picomolar potency and bypasses established resistance in multidrug‐resistant strains, demonstrating an ...

TED1 Promotes the Assembly of SCFD3‐D14‐D53 to Reinforce Strigolactone Signaling in Rice

open access: yesAdvanced Science, EarlyView.
This study identifies TED1 as a positive regulator of strigolactones (SL) signaling in rice. The ted1 mutants display dwarfism and increased tillering with significantly reduced SLs sensitivity. Through its longer C‐terminal region, TED1 interacts with D53 and D14 to promote the assembly of SCFD3‐D14‐D53, thereby facilitating the efficient ...

The evolution of covert, silent infection as a parasite strategy [PDF]

open access: yes, 2009
Many parasites and pathogens cause silent/covert infections in addition to the more obvious infectious disease-causing pathology. Here, we consider how assumptions concerning superinfection, protection and seasonal host birth and transmission rates ...

Immune responses to Fasciola hepatica infection, and Fasciola hepatica derived antigens [PDF]

open access: yes, 2003
The aim of this study was to investigate immune responses as a result of infection with the parasitic helminth, Fasciola hepatica. Analysis of IL-4 and Interferon-y cytokines described a predominant type 2 immune response in BALB/c mice infected with ...
