Formate dehydrogenase [PDF]

open access: yesFEMS Microbiology Letters, 1990
Formate is a substrate, or product, of diverse reactions catalyzed by eukaryotic organisms, eubacteria, and archaebacteria. A survey of metabolic groups reveals that formate is a common growth substrate, especially among the anaerobic eubacteria and archaebacteria.

Male triploid oysters of Crassostrea gigas exhibit defects in mitosis and meiosis during early spermatogenesis

open access: yesFEBS Open Bio, 2022
The Pacific oyster, Crassostrea gigas, is a successive irregular hermaphrodite mollusk which has an annual breeding cycle. Oysters are naturally diploid organisms, but triploid oysters have been developed for use in shellfish aquaculture, with the aim of

Characteristics of persistent hotspots of Schistosoma mansoni in western Côte d’Ivoire

open access: yesParasites & Vectors, 2020
Background Preventive chemotherapy with praziquantel is the cornerstone of schistosomiasis control. However, in some social-ecological settings, the prevalence and/or intensity of Schistosoma infection does not lower meaningfully despite multiple rounds ...

Galaxy formation [PDF]

open access: yesSymposium - International Astronomical Union, 1987
Theories of galaxy formation via hierarchical clustering of cold dark matter and by fragmentation of gaseous pancakes or shells are reviewed and compared. Dissipative processes are crucial to all theories of galaxy formation, and are discussed in terms of a simple model involving multiple cloud interactions.

Cluster formation versus star formation rates around six regions in the LMC [PDF]

open access: yes, 2004
The stellar population and star clusters around six regions in the Large Magellanic Cloud (LMC) are studied to understand the correlation between star formation and cluster formation rates.

Risk factors associated with house entry of malaria vectors in an area of Burkina Faso with high, persistent malaria transmission and high insecticide resistance

open access: yesMalaria Journal, 2021
Background In rural Burkina Faso, the primary malaria vector Anopheles gambiae sensu lato (s.l.) primarily feeds indoors at night. Identification of factors which influence mosquito house entry could lead to development of novel malaria vector control ...

ANTIBODY FORMATION [PDF]

open access: yesThe Journal of Experimental Medicine, 1963
Injection of a sufficient dose of bacteriophage ϕX 174 into guinea pigs results in the formation of rapidly sedimenting antibody molecules (19S), and later, slowly sedimenting molecules (7S). Above a threshold dose of antigen, the relative rate of 19S formation is maximal and dose-independent; below this dose, slower relative rates are obtained.

Star Formation for Predictive Primordial Galaxy Formation

open access: yes, 2015
The elegance of inflationary cosmology and cosmological perturbation theory ends with the formation of the first stars and galaxies, the initial sources of light that launched the phenomenologically rich process of cosmic reionization. Here we review the

Early planet formation as a trigger for further planet formation [PDF]

open access: yes, 1999
Recent discoveries of extrasolar planets at small orbital radii, or with significant eccentricities, indicate that interactions between massive planets and the disks of gas and dust from which they formed are vital for determining the final shape of ...

In vitro antiplasmodial and cytotoxic properties of some medicinal plants from western Burkina Faso

open access: yesAfrican Journal of Laboratory Medicine, 2013
Background: Resistance of malaria parasites to existing drugs complicates treatment, but an antimalarial vaccine that could protect against this disease is not yet available.
