Schistosomiasis affects more than 250 million people worldwide and is one of the neglected tropical diseases. Currently, the treatment of schistosomiasis relies on a single drug-praziquantel-which has led to increasing pressure from drug resistance. Therefore, there is an urgent need to find new treatments.

Article Synopsis
  • Pomacea canaliculata, an invasive South American species, is highly adaptable and genetically diverse across East and Southeast Asia, with 173 genomes studied.
  • The species' dispersal is linked to climate change and human activities, and researchers identified specific genes, like Csde1, that aid in low temperature adaptation.
  • Selection processes, such as positive and balancing selection, play a crucial role in the rapid environmental adaptation of P. canaliculata, particularly involving energy metabolism and immune response genes.

Background: Schistosomiasis is a disease primarily caused by eggs laid by pathogens called schistosomes. Among the schistosome species infecting humans, Schistosoma japonicum possesses the largest fecundity; each adult female produces an average of 3500 eggs per day. The lack of proper culture conditions supporting continuous oviposition in vitro has precluded detailed investigation of mechanisms regulating sexual maturation and egg production in Schistosoma japonicum.

Schistosomes are flatworm parasites that undergo a complex life cycle involving two hosts. The regulation of the parasite's developmental processes relies on both coding RNAs and non-coding RNAs. However, the roles of non-coding RNAs, including long non-coding RNAs (lncRNAs) in schistosomes remain largely unexplored.

Eggs laid by mature female schistosomes are primarily responsible for the pathogenesis of schistosomiasis and critical for transmission. Consequently, elucidating the mechanism of sexual maturation as well as egg production may lead to new strategies for the control of schistosomiasis. MicroRNAs (miRNAs) are involved in multiple biological processes including reproduction in many organisms, yet their roles have not been well characterized in schistosomes.

Schistosomiasis is a zoonotic parasitic disease caused by schistosome infection that severely threatens human health. Therapy relies mainly on single drug treatment with praziquantel. Therefore, there is an urgent need to develop alternative medicines.

Article Synopsis
  • Schistosomiasis is a serious parasitic disease that negatively affects health in tropical and subtropical areas, with Schistosoma japonicum having different ferritin isoforms (SjFer0, SjFer1, SjFer2) whose roles in parasite growth are not well understood.
  • Researchers constructed a phylogenetic tree to examine the evolutionary relationships of these ferritins, used RNA interference to study the effect of SjFer0 on parasite development, and employed immunofluorescence and RNA-sequencing for further analysis.
  • The findings showed that SjFer0 is distinct from the other isoforms and plays a crucial role in schistosomula growth, while SjFer1 and SjFer2 do not significantly influence growth or egg production

The evolution and adaptation of S. japonicum, a zoonotic parasite that causes human schistosomiasis, remain unclear because of the lack of whole-genome data. We construct a chromosome-level S.

Schistosoma japonicum is prevalent in Asia with a wide mammalian host range, which leads to highly harmful zoonotic parasitic diseases. Most previous transcriptomic studies have been performed on this parasite, but mainly focus on stages inside the mammalian host. Moreover, few larval transcriptomic data are available in public databases.

To investigate the effect of tension on the contractive force of muscle and nerve conduction velocity of the repaired nerve, this study was designed. Fifty-four Sprague-Dawley (SD) rats were randomly divided into 3 groups. The left gastrocnemius muscles of the rats were dissected with the neurovascular pedicles intact; the tibial nerves were cut and immediately repaired by epineurial suture.

Unlabelled: Fifteen patients with 26 nonunions of diaphyseal forearm fractures were treated with interlocking intramedullary nails and iliac bone grafts. The purpose of our study was to evaluate the rate of successful healing and complications that developed after using this technique. The mean followup was 31 months (range, 25-38 months).
