An organism's ability to thrive in changing environmental conditions requires the capacity for making flexible behavioral responses. Here we show that, in the nematode Caenorhabditis elegans, foraging responses to changes in food availability require nlp-12, a homolog of the mammalian neuropeptide cholecystokinin (CCK). nlp-12 expression is limited to a(More)
BACKGROUND C-reactive protein (CRP) is useful as marker of severity in malaria. African studies have shown that serum CRP levels correlate with parasite burden and complications in malaria, especially falciparum. However, there are very few data on CRP levels in Indian malaria patients. MATERIALS AND METHODS We assessed CRP levels in malaria patients at(More)
Sulfations of sugars, such as heparan sulfates (HS), or tyrosines require the universal sulfate donor 3'-phospho-adenosine-5'-phosphosulfate (PAPS) to be transported from the cytosol into the Golgi. Metazoan genomes encode two putative PAPS transporters (PAPST1 and PAPST2), which have been shown in vitro to preferentially transport PAPS across membranes. We(More)
Both ischemic stroke (IS) and hemorrhagic stroke (HS) are reported to occur due to thrombosis on the arteries of the brain. As diabetes mellitus is a risk factor for strokes and insulin is reported to prevent thrombosis, the role of insulin in IS and HS was investigated. Forty eight stroke victims (IS = 22, HS = 26) and equal number of aged and sex matched(More)
Paraneoplastic optic neuritis is a rare phenomenon that often presents as a diagnostic challenge. It has been mostly reported with small cell cancers or thymoma. Prompt treatment of the malignancy is the only effective therapy for the condition. Visual loss, once established usually becomes irreversible. We here report a case of paraneoplastic optic(More)
Neuromodulation enables transient restructuring of anatomically fixed neural circuits, generating alternate outputs and distinct states that allow for flexible organismal responses to changing conditions. We recently identified a requirement for the neuropeptide-like protein NLP-12, a Caenorhabditis elegans homolog of mammalian Cholecystokinin (CCK), in the(More)
BACKGROUND Prednisolone and pentoxifylline (PTX) have been shown to be individually useful in severe alcoholic hepatitis with Maddrey discriminant function (MDF) score ≥32. Previous report suggests that PTX is probably superior to prednisolone alone. However the efficacy of PTX and prednisolone combination over PTX alone in the management of acute alcoholic(More)
Introduction Sulfations are ubiquitous modifications of biological macromolecules found in all cells from bacteria to mammals. They occur as post-translational modifications of specific tyrosine residues in proteins (Moore, 2003), of polysaccharides such as heparan sulfates (HS) (Esko and Lindahl, 2001) and of small molecules such as sterols (Strott, 2002).(More)
