TL;DR: In this article, it was shown that the number of solutions of the equation ω(x 1, x 2,…, x n ) = g, with g ∊ g, defines a character of a finite group.
Abstract: Let G be a finite group and ω(x 1, x 2,…, x n ) denote the product of x 1, x 2,…, x n , in a randomly chosen order. The object of this article is to prove that the number of solutions of the equation ω(x 1, x 2,…, x n ) = g, with g ∊ G, defines a character of G.

TL;DR: An exhaustive exploratory survey on helminth parasite fauna of anuran frogs was carried out in several localities falling under 5 districts of western region of Nagaland state, finding 34 parasite species recovered from a total of 29 host species surveyed.
Abstract: An exhaustive exploratory survey on helminth parasite fauna of anuran frogs was carried out in several localities falling under 5 districts of western region of Nagaland state. Altogether 34 parasite species were recovered from a total of 29 host species surveyed. The parasite spectrum (represented in all the localities by at least one or more parasite species) comprises 2 monogenean, 15 trematode (13 adult and 2 metacercaria stages), 4 cestode (3 adult and 1 larval stages), 12 nematode and 1 acanthocephalan taxa. A checklist of both the parasite and host species with short remarks for each parasite species is provided herein.

TL;DR: Enhanced or decreased production of NO from the perfused liver under osmotic stress, in presence of stress hormones and oxidative stress reflected its potential role in cellular homeostasis and also for better adaptations under environmental challenges.
Abstract: The air-breathing singhi catfish (Heteropneustes fossilis) is frequently being challenged by bacterial contaminants, and different environmental insults like osmotic, hyper-ammonia, dehydration and oxidative stresses in its natural habitats throughout the year. The main objectives of the present investigation were to determine (a) the possible induction of inducible nitric oxide synthase (iNOS) gene with enhanced production of nitric oxide (NO) by intra-peritoneal injection of lipopolysaccharide (LPS) (a bacterial endotoxin), and (b) to determine the effects of hepatic cell volume changes due to anisotonicity or by infusion of certain metabolites, stress hormones and by induction of oxidative stress on production of NO from the iNOS-induced perfused liver of singhi catfish. Intra-peritoneal injection of LPS led to induction of iNOS gene and localized tissue specific expression of iNOS enzyme with more production and accumulation of NO in different tissues of singhi catfish. Further, changes of hydration status/cell volume, caused either by anisotonicity or by infusion of certain metabolites such as glutamine plus glycine and adenosine, affected the NO production from the perfused liver of iNOS-induced singhi catfish. In general, increase of hydration status/cell swelling due to hypotonicity caused decrease, and decrease of hydration status/cell shrinkage due to hypertonicity caused increase of NO efflux from the perfused liver, thus suggesting that changes in hydration status/cell volume of hepatic cells serve as a potent modulator for regulating the NO production. Significant increase of NO efflux from the perfused liver was also observed while infusing the liver with stress hormones like epinephrine and norepinephrine, accompanied with decrease of hydration status/cell volume of hepatic cells. Further, oxidative stress, caused due to infusion of t-butyl hydroperoxide and hydrogen peroxide separately, in the perfused liver of singhi catfish, resulted in significant increase of NO efflux accompanied with decrease of hydration status/cell volume of hepatic cells. However, the reasons for these cell volume-sensitive changes of NO efflux from the liver of singhi catfish are not fully understood with the available data. Nonetheless, enhanced or decreased production of NO from the perfused liver under osmotic stress, in presence of stress hormones and oxidative stress reflected its potential role in cellular homeostasis and also for better adaptations under environmental challenges. This is the first report of osmosensitive and oxidative stress-induced changes of NO production and efflux from the liver of any teleosts. Further, the level of expression of iNOS in this singhi catfish could also serve as an important indicator to determine the pathological status of the external environment.
