The structures of the lipopolysaccharide (LPS) core and O antigen of Bordetella bronchiseptica and Bordetella parapertussis are known, but how these two regions are linked to each other had not been determined. We have studied LPS from... more
Neutrophil infiltration into inflammatory sites is one of the hallmarks of acute inflammation. Locally produced chemotactic factors are presumed to mediate the sequence of events leading to the infiltration at inflammatory sites.... more
Resveratrol is a natural molecule with antioxidant action. Moreover, resveratrol is also considered to be a molecule with anti-inflammatory action, an effect attributed to suppression of prostaglandin (PG) biosynthesis. The aim of the... more
Phyllanthus amarus is a medicinal herb used in traditional Indian medicine for liver disorders. Several researches also show that it acts primarily in the liver, but still it remains unknown that which of these ingredients has a... more
The Escherichia coli regulatory protein RfaH contributes to efficient colonization of the mouse gut. Extraintestinal pathogenic (ExPEC) as well as non-pathogenic probiotic E. coli strains rapidly outcompeted their isogenic rfaH mutants... more
Preterm birth (PTB) is a major public health problem, with a global prevalence of 9.6% and over a million annual neonatal deaths. In a mouse model of preterm labor (PTL) induced by intravaginal administration of a subclinical dose of... more
Five new meroterpenoids, purpurogenolides A-E (1-5), and four known metabolites (6-9) were isolated from the solid substrate fermentation cultures of the fungus Penicillium purpurogenum MHz 111. The structures of the new meroterpenoids... more
Use of probiotics, alone or as adjunct to other established therapies, has been reported to have potential benefits. Recently, we have reported protective potential of probiotic against Salmonella-induced liver injury. However,... more
Our earlier studies demonstrated that representative microbial substances--lipopolysaccharide, peptidoglycan, and poly-inosine: poly-cytosine (poly(I):(C))--increased the spontaneous discharge rates and sensory-evoked responses of... more
Prior exposure to a stressor can potentiate CNS pro-inflammatory immune responses to a peripheral immune challenge. However, the neuroimmune substrate(s) mediating this effect has not been determined. The present investigation examined... more
Improved methods of cell culture from eye stalk, hepatopancreas, muscle, ovary, and hemocytes of shrimp (Penaeus vannamei) were established using synthetic media and shrimp muscle extract (SME). For hemocytes and ovarian cell cultures,... more
