Alterations in air-sac and skeleton of triploid Heteropneustes fossilis
(BLACKWELL PUBLISHING LTD, 2004-01)Triploid stinging catfish Heteropneustes fossilis, when produced by cold shock, showed abnormalities in their air-sacs and skeletons. -
Putative L-triiodothyronine receptors in the liver nuclei of mature tropical toad, Bufo melanostictus
(VERLAG Z NATURFORSCH, 2004-01)Thyroid hormones exert a major role in growth and differentiation of almost all types of tissues in animals, particularly in amphibian metamorphosis, through its specific nuclear receptor activation followed by gene ... -
Stimulation of AChE activity in relation to changes in electron microscopic structure of adult rat cerebrocortical synaptosomes pretreated with 3-5-3 '-triiodo-L-thyronine
(LIPPINCOTT WILLIAMS & WILKINS, 2003-08-06)Triiodothyronine (T-3) stimulated AChE activity in depolarization-induced intact synaptosomes (isolated from adult rat cerebral cortex) suspended in calcium-supplemented choline chloride buffer in a time-dependent manner ... -
The biology of triploid fish
(SPRINGER, 2004-12)This review deals with major areas of triploidy research in fish. It includes not only methods for induction and detection of triploidy but also the impact of triploidy on morphology, anatomy, growth, haematology, energetics, ... -
Thyroid hormone profile during annual reproductive cycle of diploid and triploid catfish, Heteropneustes fossilis (Bloch)
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-06)Triploid fishes generally show sterility along with retarded gonadal development and aneuploid gametes. In teleosts, thyroid hormones influence seasonal adaptations and annual events such as reproduction. In addition, ... -
Maintenance of brain thyroid hormone level during peripheral hypothyroid condition in adult rat
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-09-05)Thyroid hormones are essential for normal functioning of adult mammalian brain. The present investigation deals with the understanding of the time course of thyroid hormone homeostasis in adult rat brain. Animals were ... -
Alterations in enzyme activities in vital organs of triploid female catfish Heteropneustes fossilis (Bloch)
(SPRINGER, 2006-03)Triploid Heteropneustes fossilis (Bloch) showed sterility and higher growth potential than the normal diploid fish. Activities of some metabolic enzymes such as cytosolic NADP-malate dehydrogenase (NADP-MDH), mitochondrial ... -
Estradiol-17 beta: Tracing its metabolic significance in female fatbody of fifth instar larvae of silkworm, Bombyx mori L (race : Nistari)
(PERGAMON-ELSEVIER SCIENCE LTD, 2007-01-09)In recent years, various vertebrate peptide and steroid hormones have been identified in invertebrates, estradiol-17 beta (E-2) being a major one. We have specifically shown NADP-malate dehydrogenase (NADP-MDH) activity ... -
Maintenance of homeostasis for thyroid hormone in the adult rat brain: Possible involvement of a nuclear-mediated phenomenon
(KARGER, 2007)During adult-onset peripheral hypothyroidism, the brain maintains normal levels of thyroid hormone for some time through a mechanism of 'central homeostasis'. Although onset, duration, and termination of such a homeostatic ... -
Variations in hepatic estradiol-17 beta receptor concentrations during the annual reproductive cycle of diploid and triploid female catfish, Heteropneustes fossilis (Bloch)
(PERGAMON-ELSEVIER SCIENCE LTD, 2007-04-17)Concentrations of hepatic estradiol-17 beta (E2) receptors (ER) in cytosolic and nuclear fractions were evaluated in diploid and triploid female catfish Heteropneustes fossilis (Bloch) during four different reproductive ... -
Thyroid Hormone Homeostasis in Brain: Possible Involvement of Adrenergic Phenomenon in Adult Rat
(KARGER, 2009)Background: Imbalance in thyroid hormone concentrations has been linked with profound neurobehavioral alterations in the adult. Peripheral hypothyroidism is associated with a phenomenon of central thyroid hormone homeostasis ... -
Thyroid Hormone Homeostasis in Adult Mammalian Brain: A Novel Mechanism for Functional Preservation of Cerebral T3 Content During Initial Peripheral Hypothyroidism
(Dr.B.S.Patil, 2010)The essential role of thyroid hormone (TH) on the maturation and differentiation of the mammalian brain is well known. But the action of THs in the adult brain was not widely a focus of study by endocrinologists based ...
