Evaluation of some essential oils for their toxicity against fungi causing deterioration of stored food commodities.
During screening of essential oils for their antifungal activities against Aspergillus flavus, the essential oil of Cymbopogon citratus was found to exhibit fungitoxicity. The MIC of the oil was… Expand
Effects of gonadotrophin in vivo and 2-hydroxyoestradiol-17beta in vitro on follicular steroid hormone profile associated with oocyte maturation in the catfish Heteropneustes fossilis.
An HPLC method was used to tentatively identify progesterone (P4) and its metabolites (17-hydroxyprogesterone (17-P4) and 17,20beta-dihydroxy-4-pregnen-3-one (17,20beta-P)), corticosteroids (cortisol… Expand
HPLC-electrochemical detection of ovarian estradiol-17beta and catecholestrogens in the catfish Heteropneustes fossilis: seasonal and periovulatory changes.
A high performance liquid chromatography-electrochemical (HPLC-EC) detection method was used to characterize estradiol-17beta (E2) and its metabolites (2-hydroxyE2, 4-hydroxyE2, and 2-methoxyE2) and… Expand
Relative effects of estradiol-17beta (E2), catecholestrogens and clomiphene citrate on in vitro oocyte maturation in the catfish Heteropneustes fossilis (Bloch) and E2 inhibition of…
In vitro effects of estradiol-17beta (E(2)), the catecholestrogens 2-hydroxyE(2) (2-OHE(2)) and 2-methoxyE(2), and the nonsteroidal antiestrogen clomiphene citrate (clomid) on oocyte maturation were… Expand
Toxicity of three herbicides to some nitrogen-fixing cyanobacteria.
The effects of some common rice field herbicides, such as 2,4-dichlorophenoxyacetic acid (2,4-D), Machete, and Saturn, on the paddy field nitrogen-fixing cyanobacteria Nostoc linckia, Nostoc… Expand
Involvement of mitogen-activated protein kinase in 2-hydroxyestradiol-17beta-induced oocyte maturation in the catfish Heteropneustes fossilis and a note on possible interaction with protein…
Mitogen-activated protein kinase (MAPK) was demonstrated in the postvitellogenic follicles (theca-granulosa and oocyte) of catfish by Western blotting using a polyclonal anti-rabbit serum, which… Expand
Contre-coup extradural haematoma : a short report.
An extradural haematoma contralateral to impact site is reported. Review of literature reveals that such phenomenon is extremely rare.

Three pesticides (2,4-D, basalin, aldrin) inhibited L-methionine-DL-sulfoximine (MSX)-induced photoproduction of ammonia by the nitrogen-fixing cyanobacterium Nostoc linckia. Combinations of… Expand
Protection against salt toxicity in Azolla pinnata-Anabaena azollae symbiotic association by using combined-N sources.
Protection from salt stress was observed in the terms of yield (fresh and dry weight, chlorophyll and protein) and nitrogenase activity. Azollapinnata appeared highly sensitive to 40 mM external NaCl… Expand
Ovarian monosaccharides (glucose and fructose): hormonal effects and their role in final oocyte maturation and egg quality in catfish Heteropneustes fossilis, Bloch.
In the catfish H. fossilis, ovarian glucose and fructose levels showed significant annual variations that could be correlated with the gonado-somatic index. The concentration of the sugars, which was… Expand
