[Response of Topsoil Fungal Community Structure to Soil Improvement Measures in Degraded Forest of Red Soil Region].

Soil fungal community structure and diversity are highly sensitive to variations in the external environment, as well as soil improvement measures. In order to clarify the effects of soil improvement measures on topsoil fertility or quality, a field experiment was conducted in eroded forest of a red soil region. Organic fertilizer, biochar, and lime+microbial fertilizer were added to the topsoil, respectively.

Low Serum Superoxide Dismutase Is Associated With a High Risk of Cognitive Impairment After Mild Acute Ischemic Stroke.

Background: Post-stroke cognitive impairment (PSCI) is a common complication after stroke, but effective therapy is limited. Identifying potential risk factors for effective intervention is warranted. We investigated whether serum superoxide dismutase (SOD) levels were related to cognitive impairment after mild acute ischemic stroke (AIS) by using a prospective cohort design.

Effect of photoperiod change on chronobiology of cercarial emergence of Schistosoma japonicum derived from hilly and marshy regions of China.

The chronobiology of cercarial emergence appeared to be a genetically controlled behavior, adapted to definitive host species, for schistosome. However, a few physiological and ecological factors, for example the change of photoperiod, were reported to affect the rhythmic emergence of cercariae. Therefore, the effect of photoperiod change on cercarial emergence of two Schistosoma japonicum isolates, the hilly and the marshland, was investigated.

[Cloning, expression and antigenic analysis of merozoite surface protein MSPDBL2-DBL2 domain from Plasmodium falciparum].

Objective: To clone and express the DBL domain of Plasmodium falciparum merozoite surface protein MSPDBL2(DBL2), and investigate its antigenicity.

Methods: The DBL2 fragment was amplified by PCR and cloned into pET28a vector. The recombinant pET28a-DBL2 plasmid was transformed into E.
