School-age Children as Asymptomatic Malaria Reservoir in Tribal Villages of Bastar Region, Chhattisgarh.

Malaria is a major health concern in India, especially in regions populated by tribals. In this cross-sectional survey carried out in Bastar region of Chhattisgarh, 35 Plasmodium infections were detected in 451 participants screened during the non-transmission season; 27 (77.1%) were asymptomatic. Participants with age 6-14 years were at high risk of asymptomatic infection [OR 4.09, 95% CI, 1.69 to 9.89, P=0.001], and may act as an under-appreciated reservoir for sustained malaria transmission.

Micro-RNAs in inflammatory diseases and as a link between inflammation and cancer.

OBJECTIVE: The objective of this review is to examine the role of miRNA in various inflammatory diseases and in inflammatory diseases progressing to cancer. INTRODUCTION: MicroRNAs are small, conserved, non-coding RNA molecules which are present in most of the eukaryotes. miRNA have been reported to play a major role in the physiological control of gene expression and in the pathogenesis of various diseases. They regulate the gene expression mainly at the post-transcriptional level. miRNA expression profile is reported to be altered in various inflammatory diseases and subsequently affects the expression of genes, which is important in disease pathogenesis. METHODS: A Pubmed database search was performed for studies related to miRNA studies in inflammatory disease, cancer and in inflammatory diseases progressing to cancer. CONCLUSION: The evidence shows very important role of miRNA in inflammatory diseases. Few miRNAs involved in common inflammatory process and suggest miRNA as a link between inflammation and cancer. Future research should be directed to use miRNA therapeutically to target common inflammatory pathway and to develop miRNA as biomarker to detect development of cancer at early stages.
